For instance, in the case of\n\nsolving the finite-domain CSP in question amounts to solving linear equations modulo  [BK10  ###reference_bx13###, BR23  ###reference_bx26###].\nIt is known that the tractability results from [BK10  ###reference_bx13###] cannot be obtained using the reduction from [BM16  ###reference_bx17###].\nIn 2022, Mottet and Pinsker introduced the machinery of smooth approximations [MP22  ###reference_bx54###] (see also [MP24  ###reference_bx55###]), vastly generalizing the methods in [BM16  ###reference_bx17###].\nThe last section of their paper is devoted to temporal CSPs, and the authors manage to reprove a significant part of the dichotomy of Bodirsky and K\u00e1ra on just a few pages.\nThey achieve this by applying some of their general results to first-order expansions of  and obtaining either NP-hardness for the CSP, or one of the two types of symmetry that played a fundamental role in the original proof from [BK10  ###reference_bx13###].\nThis symmetry can then be used to prove correctness of the reduction to a finite-domain CSP described above.\nThe issue here is that this is essentially just a different interpretation of the algorithm of Bodirsky and K\u00e1ra [BK10  ###reference_bx13###], or rather its refinement by Bodirsky and Rydval [BR23  ###reference_bx26###];\nit is still specifically tailored to the particular \u201cbase language\u201d  (see Proposition 3.1 in [BR23  ###reference_bx26###] and the last section of [MP24  ###reference_bx55###]).\nIn contrast to the polynomial-time many-one reduction from [BM16  ###reference_bx17###] which only use finite boundedness and homogeneity as a blackbox, it can be described as language-dependent.\nMottet [Mot25  ###reference_bx53###] recently announced uniform algorithms for temporal CSPs, based on a combination of sampling and either local consistency or singleton affine integer programming.\nWe see this as a big leap from the algorithmic perspective.\nThough, the correctness proofs for said algorithms still use the ad-hoc framework of free sets from [BK10  ###reference_bx13###].\nWe do not see this as a deficiency of the approach in [Mot25  ###reference_bx53###] but rather a consequence of the fact that free sets provide natural means for describing crucial properties of Boolean combinations of linear-order constraints.\nA similar situation occurs in the case of phylogeny CSPs [BJP17  ###reference_bx12###], which capture decision problems concerning the existence of a binary tree satisfying certain constraints imposed on its leaves.\nTractable phylogeny CSPs are strikingly similar to tractable temporal CSPs; they can always be solved by a divide-and-conquer algorithm repeatedly searching for a subdivision of the input variables into two parts, which represent the two different branches below the root of a potential binary tree.\nAs with tractable temporal CSPs, each instance of the search is performed using an oracle for a tractable finite-domain CSP.\nFor tractable phylogeny CSPs, already the homogeneity of the base language is both sufficient and necessary for proving the correctness of the above described reduction to the finite-domain CSP (Theorem 6.13 and Lemma 6.12 in [BJP17  ###reference_bx12###]).\nWe can therefore speak of a case of extreme language-dependency.\nTemporal and phylogeny CSPs are special cases of CSPs of structures obtainable from the universal homogeneous binary tree [BBPP18  ###reference_bx8###] by specifying relations using first-order formulas.\nAchieving a complexity dichotomy in this context will require a non-trivial combination of the methods from [BK10  ###reference_bx13###] and [BJP17  ###reference_bx12###].\nThe language dependency issue of temporal and phylogeny CSPs reflects negatively on the attitude towards the Bodirsky-Pinsker conjecture.\nIt indicates that an optimal way of approaching the conjecture might\nbe by gaining a very good understanding of the class of reducts of finitely bounded homogeneous structures, e.g., through some sort of a classification.\nIt is unclear how realistic this prospect would be as model-theoretic properties often tend to be undecidable [Che11  ###reference_bx32###, Bra19  ###reference_bx27###] and this could include the amalgamation property.\nThe optimistic interpretation of our results points in the direction of decidability of the classification problem, but with a very impractical lower bound.\nAn alternative to facing the classification problem when approaching the Bodirsky-Pinsker conjecture is to simplify the conjecture; first steps in this direction were recently made in the preprint [PRSS25  ###reference_bx57###] where the authors reduce the scope of the conjecture to reducts of finitely bounded homogeneous structures without algebraicity, which correspond to reducts of finitely bounded strong amalgamation classes (see, e.g., [Bod21  ###reference_bx19###, Theorem 4.3.5]).\nThe restriction of the classification problem to finitely bounded strong amalgamation classes unfortunately retains the original complexity due to Theorem 1.3  ###reference_thm3###."

The need to design a network that can operate without disruption when one or more components fail has been growing dramatically.\nHenceforth, network scientists have formulated many models to address these problems. Amongst them, the simplest and arguably most fundamental problem in the area is the minimum-cost -outconnected spanning subgraph (-OCSS) problem that captures the problem of designing a multi-casting network with survivability property. The -OCSS problem is a generalization of the minimum spanning tree and the minimum-cost arborescence problems, where the goal is to design a network that can operate under failures of at most  points. More formally, -OCSS asks to find a minimum-cost subgraph such that the root vertex is -connected to every other vertex.\nIn this paper, we study the analog of -OCSS in the presence of Steiner vertices, namely the -connected directed Steiner tree problem (-DST): Given a directed graph  with cost  on arcs, a root vertex  and a set of terminals , the goal is to find a minimum-cost subgraph  such that  has  internally disjoint paths from the root  to every terminal , i.e., the root remains connected to every terminal even after the removal of  vertices (or arcs).\nThe -DST problem is a natural generalization of the classical directed Steiner tree problem (DST) to high connectivity settings.\nThe undirected counterpart of -DST is the minimum-cost single-source -(vertex)-connected subgraph problem, which admits an -approximation algorithm [Nut12  ###reference_bx39###], and the edge-connectivity variant admits a factor-two approximation algorithm due to Jain [Jai01  ###reference_bx31###].\nThe -DST problem, on the other hand, has no non-trivial approximation algorithm for , except for the special case of -layered graph, which admits -approximation algorithm due to Laekhanukit [Lae16  ###reference_bx36###].\nThe cases of  and  are also notorious problems themselves, as both admit polylogarithmic approximation algorithms that run in quasi-polynomial time, but no polynomial-time approximation algorithms with sub-polynomial approximation. It has been long-standing open problems whether such algorithms exist for DST and -DST.\nWe answer the questions regarding the approximability of -DST negatively.\nFirst, we show an approximation hardness of  for -DST under , which holds when  is much larger than , thus implying that a trivial -approximation algorithm for the problem is tight up to the lower order term.\nFor , unless , it is hard to approximate the -DST problem to within a factor of .\nAssuming the Strongish Planted Clique Hypothesis (SPCH) [MRS21  ###reference_bx38###], our hardness result is tight up to a constant factor, and it, indeed, rules out -time -approximation algorithm for any function  depending only on . See discussion in Section B.1  ###reference_###.\nAssuming the Strongish Planted Clique Hypothesis, there is no -time -approximation algorithm for the -DST problem.\nNext, we show that the -DST admits no -approximation algorithm even on an -layered graph, which consists of  parts, called layers, and every arc joins a vertex from the -th layer to the -th layer.\nIt is hard to approximate the -DST problem on -layered graphs  for  to within a factor of  for any constant , unless .\nIn addition, we obtain an approximation hardness exponential in  by setting a different parameter in the reduction, which improves upon the previously known approximation hardness of  due to Manurangsi [Man19  ###reference_bx37###] (which is in turn based on the two previous results [Lae14  ###reference_bx35###, CLNV14  ###reference_bx11###]), and is the first known approximation hardness for connectivity problems whose ratio is exponential in the connectivity requirement.\nIt is hard to approximate the -DST problem to within a factor of , unless .\nUsing the technique of Cheriyan, Laekhanukit, Naves and Vetta [CLNV14  ###reference_bx11###], which is based on the padding technique introduced by Kortsarz, Krauthgamer and Lee [KKL04  ###reference_bx32###], we extend our hardness result to the undirected counterpart of -DST, namely, the single source -vertex-connected Steiner tree problem (-ST) (a.k.a. undirected rooted subset -connectivity, shorty, rooted--VC) and the special case of -DST, namely -edge-connected group Steiner tree problem (-GST).\nThe latter problem is a natural fault-tolerant generalization of the classical group Steiner tree problem [GKR00  ###reference_bx21###], which has been studied in [KKN12  ###reference_bx33###, GKR10  ###reference_bx22###, CGL15  ###reference_bx9###, CDE+18  ###reference_bx5###].\nTo the best of our knowledge, a non-trivial approximation algorithm for this problem is known only for . For , only a bicriteria approximation algorithm, where the connectivity requirement can be dropped by a factor , is known in [CGL15  ###reference_bx9###]. Nevertheless, a trivial -approximation algorithm exists for all values of  and we also show its tightness (up to the lower order term) for sufficiently large .\nFor , unless , it is hard to approximate the -ST problem to within a factor of .\nFor , unless , it is hard to approximate the -GST problem to within a factor of , where  is the number of groups."

The SPCH asserts that there exists no bounded-error probabilistic polynomial time algorithm that can distinguish the two cases in -time.\nUnder this complexity assumption, Manurangsi, Rubinstein and Schramm showed that a -CSP, particularly, the densest -subgraph problem (DS) admits no polynomial-time -approximation algorithm.\nTo be precise, in the DS problem, we are given a graph  and an integer . The goal is to find a subset of  vertices that spans the maximum number of edges.

+    "title": "Sequential Bayesian Neural Subnetwork Ensembles",
+    "abstract": "Deep ensembles have emerged as a powerful technique for improving predictive performance and enhancing model robustness across various applications by leveraging model diversity. However, traditional deep ensemble methods are often computationally expensive and rely on deterministic models, which may limit their flexibility. Additionally, while sparse subnetworks of dense models have shown promise in matching the performance of their dense counterparts and even enhancing robustness, existing methods for inducing sparsity typically incur training costs comparable to those of training a single dense model, as they either gradually prune the network during training or apply thresholding post-training. In light of these challenges, we propose an approach for sequential ensembling of dynamic Bayesian neural subnetworks that consistently maintains reduced model complexity throughout the training process while generating diverse ensembles in a single forward pass. Our approach involves an initial exploration phase to identify high-performing regions within the parameter space, followed by multiple exploitation phases that take advantage of the compactness of the sparse model. These exploitation phases quickly converge to different minima in the energy landscape, corresponding to high-performing subnetworks that together form a diverse and robust ensemble. We empirically demonstrate that our proposed approach outperforms traditional dense and sparse deterministic and Bayesian ensemble models in terms of prediction accuracy, uncertainty estimation, out-of-distribution detection, and adversarial robustness.",

+            "text": "Deep learning has powere state-of-the-art performance in a wide array of machine learning tasks (LeCun, Bengio, and Hinton 2015  ###reference_b29###). However, deep learning models still face many fundamental issues from the perspective of statistical modeling, which are crucial in many fields including autonomous driving, healthcare, and science (Bartlett, Montanari, and Rakhlin 2021  ###reference_b2###). One of the major challenges is their ability to reliably estimate model uncertainty while capturing complex data dependencies and being computationally tractable. Probabilistic machine learning, especially the Bayesian framework, offers an exciting avenue to address these challenges. Besides superior uncertainty quantification, Bayesian models exhibit improved robustness to noise and adversarial perturbations (Wicker et al. 2021  ###reference_b50###) due to probabilistic prediction capabilities. Bayesian neural networks (BNNs) have pushed the envelope of probabilistic machine learning through the combination of deep neural network (DNN) architecture and Bayesian inference. However, due to the enormous number of parameters, BNNs adopt approximate inference techniques such as variational inference with a fully factorized approximating family (Jordan et al. 1999  ###reference_b24###). Although this approximation is crucial for computational tractability, it may under-utilize BNN\u2019s true potential (Izmailov et al. 2021  ###reference_b20###).\n###figure_1### Ensembles of neural networks (Lakshminarayanan, Pritzel, and\nBlundell 2017  ###reference_b28###) have been proposed to account for the parameter/model uncertainty, which are shown to be analogous to Bayesian model averaging and sampling from the parameter posteriors to estimate the posterior predictive distribution (Wilson and Izmailov 2020  ###reference_b51###). In this spirit, ensemble diversity is a key to enhancing predictions, uncertainty, and robustness. To this end, diverse ensembles can mitigate shortcomings of approximate Bayesian inference without sacrificing computational efficiency. In past, various diversity-inducing techniques have been explored, including using specific learning rate schedule (Huang et al. 2017  ###reference_b19###), kernalized repulsion terms in the loss function (D\u2019Angelo and Fortuin 2021  ###reference_b5###), mixtures of approximate posteriors capturing multiple posterior modes (Dusenberry et al. 2020  ###reference_b6###), sparsity as a mechanism for diversity (Havasi et al. 2021  ###reference_b16###; Liu et al. 2022  ###reference_b32###), and diversity in model architectures via neural architecture and hyperparameter searches (Egele et al. 2022  ###reference_b7###; Wenzel et al. 2020  ###reference_b49###).\nHowever, most approaches use parallel ensembles, where individual model part starts with a different initialization. This can be computationally expensive, as each ensemble member requires extended training to reach a high-performing neighborhood of the parameter space. Although ensemble diversity is emphasized, the training cost is often overlooked. With the size of models only growing as we advance in deep learning, reducing the training cost of ensemble models alongside increasing their diversity is crucial.\nSequential ensembling offers an elegant solution to reduce the cost of obtaining multiple ensembles, with roots in methods that combine learning trajectory epochs (Swann and Allinson 1998  ###reference_b44###; Xie, Xu, and Chuang 2013  ###reference_b52###). (Jean et al. 2015  ###reference_b23###; Sennrich, Haddow, and Birch 2016  ###reference_b40###) leverage intermediate training stages, while (Moghimi et al. 2016  ###reference_b34###) uses boosting to generate ensembles. Recent methods (Huang et al. 2017  ###reference_b19###; Garipov et al. 2018  ###reference_b11###; Liu et al. 2022  ###reference_b32###) employ cyclic learning rate annealing to force the model to visit multiple local minimas, collecting ensembles at each local minimum. All these techniques have been primarily applied to deterministic models. Extending sequential ensembling to Bayesian models is attractive as it can allow creation of high-performing ensembles without the need to train from scratch, similar to sampling a posterior distribution with a Markov chain Monte Carlo sampler. Sequential ensembling can also complement parallel ensembling, where each parallel ensemble can generate multiple sequential ensembles, increasing the overall diversity of the final ensemble model.\nA new frontier for improving the computational tractability and robustness of neural networks is sparsity (Hoefler et al. 2021  ###reference_b18###). Famously, the lottery ticket hypothesis (Frankle and Carbin 2019  ###reference_b9###) established the existence of sparse subnetworks that can match the performance of the dense model. Studies have also shown that such subnetworks tend to be inherently diverse due to different neural connectivity (Havasi et al. 2021  ###reference_b16###; Liu et al. 2022  ###reference_b32###; Yin et al. 2023  ###reference_b53###). However, most sparsity-inducing techniques have focused on deterministic networks, using post-hoc pruning (Han, Mao, and Dally 2016  ###reference_b13###; Molchanov, Ashukha, and Vetrov 2017  ###reference_b35###). In Bayesian learning, the prior distribution provides a systematic approach to incorporate inductive bias and expert knowledge directly into the model (Robert et al. 2007  ###reference_b39###). Consequently, sparsity in Bayesian neural networks can be introduced via sparsity-inducing priors (Louizos, Ullrich, and Welling 2017  ###reference_b33###; Bai, Song, and Cheng 2020  ###reference_b1###; Ghosh, Yao, and Doshi-Velez 2019  ###reference_b12###; Jantre, Bhattacharya, and\nMaiti 2023a  ###reference_b21###, b  ###reference_b22###) which either incorporate sparsity gradually during training or post-training using thresholding criteria. These approaches successfully reduce computational and memory costs during inference, but their training costs remain similar to those of dense models.\nTo this end, we propose Sequential Bayesian Neural Subnetwork Ensembles (SeBayS) with the following key contributions:\nWe propose a sequential ensembling strategy for Bayesian neural networks (BNNs) which learns multiple subnetworks in a single forward-pass utilizing a fully sparse Bayesian framework that embeds sparsity in the posterior from the start of training. The approach involves a single exploration phase to find high-performing sparse network connectivity followed by multiple exploitation phases to obtain multiple subnetworks for ensembling.\nWe leverage the light-weight dynamic sparsity learning to efficiently generate diverse sparse Bayesian neural networks, which we refer to as Bayesian neural subnetworks. Our approach outperforms current state-of-the-art methods in terms of predictive accuracy, uncertainty estimation, out-of-distribution detection, and adversarial robustness."

The most simple and widely used approach is Monte Carlo dropout, which is based on Bernoulli noise (Gal and Ghahramani 2016  ###reference_b10###) and deactivates certain units during training and testing. This, along with techniques such as DropConnect (Wan et al. 2013  ###reference_b47###), Swapout (Singh, Hoiem, and Forsyth 2016  ###reference_b41###) are referred to as\u201cimplicit\u201d ensembles as model ensembling is happening internally in a single model. Although they are efficient, the gain in accuracy and robustness is limited, and they are mainly used in the context of deterministic models. Although most recent approaches have targeted parallel ensembling techniques, few approaches such as BatchEnsemble (Wen, Tran, and Ba 2020  ###reference_b48###) appealed to parameter efficiency by decomposing ensemble members into a product of a shared matrix and a rank-one matrix, and using the latter for ensembling and MIMO (Havasi et al. 2021  ###reference_b16###) which discovers subnetworks from a larger network via multi-input multi-output configuration. In the context of Bayesian neural network ensembles, (Dusenberry et al. 2020  ###reference_b6###) proposed a rank-1 parameterization of BNNs, where each weight matrix involves only a distribution on a rank-1 subspace and uses mixture approximate posteriors to capture multiple modes. (Premchandar et al. 2022  ###reference_b38###) employ weight space ensembling with distribution learning of architectures for improved robustness.\nSequential ensembling techniques offer an elegant solution to ensemble training but have not received much attention recently due to a wider focus of the community on diversity of ensembles and less on the computational cost. Notable sequential ensembling techniques are  (Huang et al. 2017  ###reference_b19###; Garipov et al. 2018  ###reference_b11###; Liu et al. 2022  ###reference_b32###) that enable the model to visit multiple local minima through cyclic learning rate annealing and collect ensembles only when the model reaches a local minimum. The difference is that  (Huang et al. 2017  ###reference_b19###) adopts cyclic cosine annealing,  (Garipov et al. 2018  ###reference_b11###) uses a piece-wise linear cyclic learning rate schedule that is inspired by geometric insights. Finally,  (Liu et al. 2022  ###reference_b32###) adopts a piece-wise constant cyclic learning rate schedule. We also note that all of these approaches have been primarily in the context of deterministic neural networks.\nOur approach (i) introduces sequential ensembling into Bayesian neural networks, (ii) combines it with dynamic sparsity learning for cheaply collecting Bayesian subnetworks, and (iii) efficiently produces diverse model ensembles. It complements other parallel and efficient ensemble methods."

We demonstrate that the SeBayS and BayS ensembles outperform static sparse, DST, and EDST ensembles in terms of average robust accuracy. Furthermore, the robustness of the SeBayS and BayS ensembles is comparable to that of single dense DNN and BNN models, with the BayS ensemble outperforming the dense BNN ensemble on average.\n###table_6###"

In contrast, for the unweighted version, NP-completeness is only known for planar graphs of maximum degree . In fact, the complexity of unweighted Edge Multiway Cut was open for graphs of maximum degree  for over twenty years. We prove that the unweighted version is NP-complete even for planar graphs of maximum degree . As weighted Edge Multiway Cut is polynomial-time solvable for graphs of maximum degree at most , we have now closed the complexity gap. We also prove that (unweighted) Node Multiway Cut (both with and without deletable terminals) is NP-complete for planar graphs of maximum degree . By combining our results with known results, we can apply two meta-classifications on graph containment from the literature. This yields full dichotomies for all three problems on -topological-minor-free graphs and, should  be finite, on -subgraph-free graphs as well.\nPreviously, such dichotomies were only implied for -minor-free graphs.",

The problems can be thought of as the natural dual problems of the Steiner Tree problem.\nIn their famous study of Edge Multiway Cut, Dahlhaus et al.

[16  ###reference_b16###] showed the same for Node Multiway Cut.\nWe note that this is a tight result: if , then both problems reduce to the Minimum Cut problem.

However, for terminal vertices of high degree, a local replacement strategy seems impossible. Hence, the fact that terminals in the construction of Dahlhaus et al.

Given a CNF-formula  with the set of variables  and the set of clauses , the incidence graph of the formula is the graph  which is a bipartite graph with one of the partitions containing a vertex for each variable and the other partition containing a vertex for each clause of . There exists in  an edge between a variable-vertex and a clause-vertex if and only if the variable appears in the clause. We define Planar 2P1N-3SAT as follows.\nPlanar 2P1N-3SATA set  of variables and a CNF formula  over  and clause set  with each clause containing at most three literals and each variable occurring twice positively and once negatively in  such that  is planar.Is there an assignment  that satisfies ?\nThe above problem was shown to be NP-complete by\nDahlhaus et al. [13  ###reference_b13###]. By their construction, each variable occurs in at least two clauses having size . This property becomes important later in our NP-completeness proof.\nWe need two further definitions. Recall that in Weighted Edge Multiway Cut, we are given a function  in addition to . The goal is to decide if  admits an edge multiway cut of total weight at most . If the image of  is the set , we denote the corresponding Weighted Edge Multiway Cut problem as -Edge Multiway Cut. Also note that if an edge/node multiway cut  has smallest possible size (weight) among all edge/node multiway cuts for the pair , then  is a minimum(-weight) edge/node multiway cut.\nWe show the reduction in two steps. In the first step, we reduce from Planar 2P1N-3SAT to -Edge Multiway Cut restricted to planar graphs of maximum degree  where the terminals all have degree . In the second step, we show how to make the instance unweighted while keeping it planar and making its maximum degree bounded above by .\nSee 1.1  ###reference_theorem1###\nClearly, Edge Multiway Cut is in NP.\nWe reduce Edge Multiway Cut from Planar 2P1N-3SAT. Let  be a given CNF formula with at most three literals in each clause and each variable occurring twice positively and once negatively.\nWe assume that each clause has size at least  and every variable occurs in at least two clauses of size . Let  be the set of variables in  and  be the set of clauses. We assume that the incidence graph  is planar. By the reduction\nof Dahlhaus et al. [13  ###reference_b13###], Planar 2P1N-3SAT is NP-complete for such instances.\n###figure_5### We now describe the graph construction. For each vertex of  corresponding to a clause  in , we create a clause gadget (depending on the size of the clause), as in Figure 3  ###reference_###. For each vertex of  corresponding to a variable , we create a variable gadget, also shown in Figure 3  ###reference_###. The gadgets have two terminals each (marked as red squares in Figure 3  ###reference_###), a positive and a negative one. In a variable gadget, the positive terminal is attached to the diamond and the negative one to the hat, by edges of weight ; refer to Figure 3  ###reference_###. In a clause gadget, each literal corresponds to a triangle, with these triangles connected in sequence, and the positive and negative terminal are attached to triangles at the start and end of the sequence, again by edges of weight .\nEach degree- vertex in a gadget (marked blue in Figure 3  ###reference_###) is called a link. The two edges incident on a link are called connector-edges. The edge of such a triangle that is not incident on the link is called the base of the triangle. For a variable , if  and  for clauses , then we connect the links of the diamond of  to some link of the gadgets for  and , each by identifying them with the respective link in the clause gadget. If  for clause , then we connect the link of the hat of  and some link on the gadget for , again by identifying the two links. An example of such variable and clause connections is depicted in Figure 6  ###reference_###. The structure formed by the link and the four connector-edges incident on it, is referred to as a link-structure. By the assumptions on , we can create the link-structures such that each link in the variable gadget participates in exactly one link-structure and corresponds to one occurrence of the variable. Similarly, each link of a clause gadget participates in exactly one link-structure.\nThe graph thus created is denoted by . We can construct  in such a way that it is planar, because  is planar and has maximum degree . Note that  has maximum degree . Let  be the set of terminals in the constructed graph . Note that  has a total of  terminals.\nWe observe that all edges in  have weight at most . Non-terminal vertices are incident on edges of total weight at most . Crucially, terminals are incident on edges of total weight at most .\n###figure_6### We introduce some extra notions to describe the constructed graph . The connector-edges closest to the terminals are called outer edges, as indicated in Figure 3  ###reference_###. The structure formed by the two pairs of connector-edges and the link is called the link-structure; see Figure 4  ###reference_fig1###. Since each variable occurs twice positively and once negatively in , the constructed graph  has exactly  link-structures.\nWe now continue the reduction to obtain an unweighted planar subcubic graph.\nWe replace all the edges in  of weight greater than  by as many parallel edges between their end-vertices as the weight of the edge. Each of these parallel edges has weight . We refer to this graph as . Next, for each vertex  in  of degree greater than , we replace  by a large honeycomb (hexagonal grid), as depicted in Figure 5  ###reference_###, of  cells (these numbers are picked for convenience and not optimized). The neighbours of , of which there are at most six by the construction of , are now attached to distinct degree- vertices on the boundary of the honeycomb such that the distance along the boundary between any pair of them is  cells of the honeycomb. These degree- vertices on the boundary are called the attachment points of the honeycomb. The edges not belonging to the honeycomb that are incident on these attachment points are called attaching edges. In the construction, we ensure that the attaching edges occur in the same cyclical order on the boundary as the edges to the neighbours of  originally occurred around . Let the resultant graph be .\n###figure_7### Note that the degree of any vertex in  is at most . For terminals, this was already the case in . Note that, therefore, terminals were not replaced by honeycombs to obtain . For non-terminals, this is clear from the construction of  and . Moreover, all the edge weights of  are equal to , and thus we can consider it unweighted. Also, all the replacements can be done as to retain a planar embedding of  and hence,  is planar.  has size bounded by a polynomial in  and can be constructed in polynomial time. Finally, we set .\nFor the sake of simplicity, we shall first argue that  is a yes instance of Planar 2P1N-3SAT if and only if  is a yes instance of -Edge Multiway Cut. Later, we show that the same holds for  by proving that no edge of any of the honeycombs is ever present in any minimum edge multiway cut in .\nSuppose that  is a truth assignment satisfying . Then, we create a set of edges , as follows:\nIf a variable is set to \u201ctrue\u201d by , then add to  all the three edges of the hat in the corresponding gadget. If a variable is set to \u201cfalse\u201d by , then add to  all the five edges of the diamond.\nFor each clause, pick a true literal in it and add to  all the three edges of the clause-triangle corresponding to this literal.\nFinally, for each link-structure with none of its edges in  yet, add the two connector-edges of its clause-triangle to .\nis an edge multiway cut of  of weight at most .\nFor each variable, either the positive literal is true, or the negative one. Hence, either all the three edges of its hat are in  or all the five edges of the diamond. Therefore, all the paths between terminal pairs of the form , for all , are disconnected in . Consider the link-structure in Figure 4  ###reference_fig1###. By our choice of , at least one endpoint of each link in  is a vertex of degree , hence a dead end. Therefore, no path connecting any terminal pair in  passes through any link. As all the paths in  between a variable-terminal and a clause-terminal must pass through some link, we know that all terminal pairs of this type are disconnected in . Since  is a satisfying truth assignment of , all the edges of one triangle from every clause gadget are in . Hence, all the paths between terminal pairs of the form , for all , are disconnected in . Hence,  is an edge multiway cut.\nIt remains to show that the weight of  is at most . Since  satisfies each clause of , there are exactly  triangle-bases of weight 2 from the clause gadgets in . Similarly, the variable gadgets contribute exactly  bases to . Finally, for each of the  link-structures, by the definition of \nand the fact that  is a satisfying assignment,\neither the two connector-edges of the variable-triangle are in  or the two connector-edges of the clause-triangle. Together, they contribute a weight of  to the total weight of . Therefore,  is an edge multiway cut in  of weight at most .\nHence,  is a yes instance of -Edge Multiway Cut.\nConversely, assume that  is a yes instance of -Edge Multiway Cut. Hence, there exists an edge multiway cut of  of weight at most . We shall demonstrate an assignment that satisfies . Before that, we shall discuss some structural properties of a minimum-weight edge multiway cut. In the following arguments, we assume that the clauses under consideration have size three, unless otherwise specified. While making the same arguments for clauses of size  is easier, we prefer to argue about clauses of size three for generality.\nIf  is an edge in  incident on a non-terminal vertex  of degree  such that  has weight greater than or equal to the sum of the other edges incident on , then there exists a minimum-weight edge multiway cut in  that does not contain .\nThe above claim implies that there exists a minimum-weight multiway cut containing no such edge . To see this, note that an iterative application of the local replacement used in Claim 2  ###reference_2### would cause a conflict in the event that the replacement is cyclical. Suppose that the edges are replaced in the sequence . Then the weight of , denoted by  must be strictly less than the weight of . Similarly,  for . This would mean that , which is a contradiction.\nIf a minimum-weight edge multiway cut contains an edge of a cycle, then it contains at least two edges from that cycle.\nIt follows from Claim 2  ###reference_2### and the construction of  that there exists a minimum-weight edge multiway cut for  that does not contain the edges incident on the terminals. Among the minimum-weight edge multiway cuts that satisfy Claim 2  ###reference_2###, we shall select one that contains the maximum number of connector-edges and from the ones that satisfy both the aforementioned properties, we shall pick one that contains the maximum number of triangle-bases from clause gadgets of size . Let  be a minimum edge multiway cut that fulfils all these requirements.\nWe say a link  incident on a gadget reaches a terminal  if  is the first vertex on a path  from the gadget to  and no edge on  is contained in .\nA terminal  is reachable by a gadget if one of the links incident on the gadget reaches . Note that, for any terminal  in the gadget, if  is reached from some incident link by a path , then  can be extended to a - path in  using only edges inside the gadget. However, among the edges used by such an extension, at least one must belong to , or else .\n###figure_8### contains exactly one base of a triangle from each variable gadget.\nClearly,  must contain at least one base from each variable gadget, else by the fact that  contains no edges incident on terminals, a path between the terminals in such a gadget would remain in .\nSuppose that  contains two bases of some variable gadget, say that of . By Claim 3  ###reference_3###,  must also contain at least three connector-edges from this variable gadget: at least two connector-edges (of the two triangles) of the diamond and at least one connector-edge of the hat. We claim that, without loss of generality, at least all the outer connector-edges must be in . If for some triangle the outer connector-edge next to terminal  is not in , then the link incident on this triangle does not reach any terminal ; otherwise, a - path would remain in , a contradiction. Hence, we simultaneously replace all inner connector-edges for which the corresponding outer connector-edge is not in  by their corresponding outer connector-edge. For the resulting set , the variable terminals of the gadget and their neighbours in  form a connected component of . Since the link incident on a triangle for which the outer connector-edge (next to terminal ) was not in  does not reach any terminal ,  is feasible. Moreover, it has the same properties we demanded of . Thus, henceforth, we may assume that all the outer connector-edges of the -gadget are in .\nWe now distinguish six cases based on how many links of the gadget reach a terminal:\nCase 1. No link of the  gadget reaches a terminal. \nWe can remove one of the two bases from  without connecting any terminal pairs. This is so because in order to disconnect  from , it suffices for  to contain either the base of the diamond along with the two outer connector-edges or the base and outer connector-edge of the hat. No other terminal pairs are connected via the gadget by the assumption of this case. Hence, we contradict the minimality of  (refer to Figure 7  ###reference_###).\n###figure_9### ###figure_10### Case 2. A link of the -gadget reaches at least two distinct terminals. \nBy the definition of reaches, this implies that there is a path in  between any two of the reached terminals (see Figure 8  ###reference_###). This contradicts that  is an edge multiway cut for .\n###figure_11### Case 3.Exactly one link  of the -gadget reaches some terminal . \nWe remove from  the base of a triangle that is not attached to  and add the remaining connector-edge of the triangle that is attached to  (if it is not already in ). Refer to Figure 9  ###reference_###. Consequently, although  reaches , both connector-edges incident on  are in . Since no other link reached any terminals and  remains disconnected from  in , we can obtain an edge multiway cut for  satisfying Claim 2  ###reference_2### that has the same or less weight as , but has strictly more connector-edges than . This is a contradiction to our choice of .\n###figure_12### Case 4. Exactly two links  of the -gadget reach two distinct terminals  and , respectively. \nRecall that all three outer connector-edges are in . Now at least one of the inner connector-edges of the gadget must be in , or else  would be connected to  via this gadget. In particular, both the connector-edges of at least one of the two triangles attached to  must be in . Figure 10  ###reference_### depicts this scenario. We can remove from  one of the two bases and add instead the remaining connector-edge of the other triangle (if it is not already in ). Consequently, although  reaches  and  reaches , all connector-edges incident on  and  are in . Moreover,  and  are not connected to each other in , as one base and its corresponding outer connector(s) are still in . The transformation results in an edge multiway cut for  satisfying Claim 2  ###reference_2### that has the same or less weight than , but has strictly more connector-edges than . This is a contradiction to our choice of .\n###figure_13### Case 5. All the three links of the -gadget reach distinct terminals , respectively.\nRecall that all three outer connected edges are in . Now at most one (inner) connector-edge of the -gadget is not in , or else at least one pair of terminals among  would remain connected via the gadget. Consider Figure 11  ###reference_### for a visual depiction of this case. We replace one of the bases in  with this connector-edge (if it is not already in ). The resulting edge multiway cut is no heavier. To see that it is also feasible, note that while  are still reached from the links of the gadget, all the connector-edges of this gadget are in the edge multiway cut. The terminals  and  are disconnected from each other in  because one triangle-base and its connectors are still in the edge multiway cut. Hence, we obtain an edge multiway cut for  satisfying Claim 2  ###reference_2### that has the same or less weight than , but with strictly more connector-edges than , a contradiction to our choice of .\n###figure_14### Case 6. At least two links of the -gadget reach exactly one terminal  outside the gadget. \nRecall that every variable occurs in at least two clauses of size . Hence,  is reachable via a link from the -gadget to at least one directly linked clause gadget of a clause of size . Also recall that  is a minimum-weight edge multiway cut containing the maximum number of bases from clauses of size .\nSuppose that there exists a size- clause gadget , directly linked to the -gadget, that does not contain  and via which  is reachable from the -gadget.\nThat is, some link reaches  via a path  that contains edges of , but  is not in . Refer to Figure 12  ###reference_### for a visual depiction.\nThen  must contain two base-connector pairs from ; else, some terminal of  would not be disconnected from  in . Now remove from  the base of one of the two triangles of  and add the remaining two connector-edges of . This does not increase the weight, as the base of the clause-triangle has weight  and the connectors have weight  each. The only terminal pair that could get connected by the transformation is the pair of terminals on  itself. However, one of the bases is still in the transformed cut. This new cut contradicts our choice of , as it has strictly more connector-edges and satisfies the other conditions.\nSuppose  is contained in one of the size- clause gadgets , directly linked to the -gadget. If the link between the -gadget and  is not one of the links meant in the assumption of this case, then the situation of the previous paragraph holds and we obtain a contradiction.\nThus,  is reachable from the -gadget via both links of .\nHence, a base-connector pair of the triangle of  that  is not attached to must be in . Consider the link of the -gadget that is not linked to  but reaches  and let  be a corresponding path, starting at this link and going to . Note that  passes through a clause gadget  directly linked to the -gadget. If  is a size- clause gadget, then we obtain a contradiction as before. Hence,  corresponds to a size- clause (as in Figure 13  ###reference_###). Since  must either enter or leave  through one of its outer triangles, a base-connector pair of at least one outer triangle of  must be in , or the attached terminal would reach  in , contradicting that  is an edge multiway cut for . Let  be such an outer triangle (see Figure 13  ###reference_###).\n###figure_15### We argue that, without loss of generality,  contains a base-connector pair of the other outer triangle, . Suppose not. Then, in particular, the base of  is not in . If  passes through the link attached to , then one of the endpoints of the base of  must be on . Since the base of  is not in , the terminal  next to  remains connected to  in , a contradiction. Hence,  must either enter or exit  via the link attached to its middle triangle . Moreover,  must contain a base-connector pair of  (see Figure 13  ###reference_###), or  would still reach  in . We now modify  to obtain a set . If both connector-edges of  are in , then replace the base of  by the base of  to obtain . Then all edges of  are in . Otherwise, no edge of  is in  and thus no terminal must be reachable via the link attached to  (or it would be connected to  in ). So, we replace the base-connector pair of  by a base-connector pair of  to obtain . Then  is an edge multiway cut for  of the same weight at  that has the same properties as . Hence, we may assume . Then  contains a base-connector pair of .\nNow remove from  the base and connector-edge of . Then  and  become connected to each other in , but not to any other terminal, or that terminal would already be connected to  in . Now add the base and outer connector-edge of the triangle in  that  is attached to. This restores that  is an edge multiway cut for .\nThe edge multiway cut we obtain has the same weight as  and satisfies Claim 2  ###reference_2###. Moreover, it has no less connectors than  but contains at least one more base of a clause gadget of size . Hence, we obtain a contradiction to our choice of .\nWe now focus on the link-structures.\nThere cannot exist a link-structure in  that contributes less than two edges to  and for which the clause-triangle of the link-structure contributes no connector-edges to .\nTowards a contradiction, suppose that such a link-structure exists. Let the clause gadget containing the link-structure be  and the variable gadget containing it be . By Claim 4  ###reference_4###, we know that there exists a triangle of the -gadget that does not contribute its base to . Therefore, at least one terminal  of the -gadget is reachable from the clause gadget . This implies that the clause-triangle of the link-structure is the middle triangle of ;\nelse, there would exist a path in  between  and the closest clause-terminal on , because the edge incident on this terminal is also not in  by its properties.\nThen, since  is feasible, it must contain the base and at least one connector-edge of each of the two outer triangles of . Else, at least one of the clause-terminals would be reachable from  in .\nIt must also be the case that both connector-edges of each of the outer triangles must be in  or the incident link reaches no terminal ; otherwise,  or the incident clause-terminal would be connected to  in .\nNow, we can remove one of the two bases from  and add the two connector-edges of the middle triangle, without compromising the feasibility of the edge multiway cut. Thus, there exists an edge multiway cut of no greater weight than , satisfying Claim 2  ###reference_2###, and containing two more connector-edges (those of the clause-triangle of the link-structure). This is a contradiction to our choice of .\n###figure_16### contains at least two edges from each link-structure.\nSuppose that there exists a link-structure  that contributes less than two edges to . Suppose that  connects the clause gadget  and the variable gadget . By Claim 5  ###reference_5###, we know that the clause-triangle of  must contribute an edge  to . Therefore, none of the connectors of the variable-triangle attached to  are in . As a result, the variable-terminal of the -gadget attached to , say we call it , is reachable from  via .\nBy Claim 3  ###reference_3### and the fact that only  is in , the base of the clause-triangle must also be in . We do the following replacement: remove from  the base-connector pair of the clause-triangle and add the base and (possibly two) connectors of the variable-triangle of , as follows. If the variable-triangle of  is part of a diamond, then we add to  the base and two outer connectors, thereby getting an edge multiway cut of equal weight but strictly more connectors. If the variable-triangle is a hat, then we add to  the base and outer connector of the hat, obtaining an edge multiway cut for  of strictly smaller weight than . If we can show that the resultant edge multiway cut is feasible, we obtain a contradiction in either scenario. We claim that such a replacement does not compromise the feasibility of .\nLet  be the endpoints of the base of the clause-triangle of , where  is the endpoint on which  is incident (see Figure 14  ###reference_###).\nNote that no terminal other than  should be reachable in  from ; else, there would be a path from  to that terminal via . In particular, the terminal of the clause gadget for  on the side of  cannot be reached in  from the vertex . By removing the base-connector pair of the clause-triangle of , we may expose the clause-terminal on the side of the vertex  (or another terminal outside ) to . However, by adding the base and (possibly two) connectors closest to , we disconnect any path between this terminal and . Since we did not modify the cut in any other way, no new connections would have been made. This shows the feasibility of the resultant edge multiway cut and thus proves our claim.\nIf there exists an edge multiway cut of weight at most  for , then there exists a satisfying truth assignment for .\nLet  be the edge multiway cut defined before. The immediate consequence of Claims 4  ###reference_4### and 6  ###reference_6### is that the weight of  is at least .  must also contain at least one base per clause gadget lest the two terminals on a clause gadget remain connected. Therefore, its weight is at least . Since it is an edge multiway cut of weight at most , it has exactly one base per clause gadget.\nWe also claim that for each link-structure, if one of the triangles attached to it has its base in , then the other one cannot: note that if both the triangles had their bases in , then each of them would also have a connector-edge in  by Claim 3  ###reference_3###. By Claim 6  ###reference_6### and the assumption that the weight of  is at most , the other two connector-edges of the link-structure are not in . Since at most one base per variable/clause gadget can be in , there would be a path between one of the variable-terminals and one of the clause-terminals in the linked gadgets through the link-structure, a contradiction to  being an edge multiway cut for . Figure 15  ###reference_### shows one such case.\n###figure_17### We now define the truth assignment . For each variable-terminal, if the diamond has its base in , we make it \u201cfalse\u201d, otherwise if the hat has its base in  we make it \u201ctrue\". Each clause gadget has exactly one triangle contributing its base to . From the above argument, we know that the variable-triangle linked to this clause-triangle must not contribute its base to . Hence, every clause gadget is attached to one literal triangle such that its base is not in , and is therefore \u201ctrue\u201d. Hence, every clause is satisfied by the truth assignment  and  is a yes instance of Planar 2P1N-3SAT.\nThe above implies that -Edge Multiway Cut is NP-complete on planar subcubic graphs. We now proceed to prove that (unweighted) Edge Multiway Cut is NP-complete on planar subcubic graphs. The proof follows from the\nclaim below, which states\nthat the honeycombs of  (defined before) do not contribute any edge to any minimum edge multiway cut for ().\nAny minimum edge multiway cut for  does not contain any of the honeycomb edges.\nLet  be a minimum edge multiway cut for . Recall that  is planar. Note that for any two vertices , an - cut in a planar graph corresponds to a simple (possibly degenerate) cycle in the planar dual [25  ###reference_b25###]. Therefore, the dual of an edge multiway cut comprises several cycles. Let the edges corresponding to  in the planar dual of  be . In fact,  induces a planar graph such that exactly one terminal of  is embedded in the interior of each face of this graph. If any face of  did not contain a terminal, we could remove the edge in  dual to one of the edges of this face. This would not connect any terminal pair, and hence contradicts the minimality of .\nSuppose that  contains some of the edges of the honeycomb in  replacing the vertex . We denote the intersection of  with the edges of this honeycomb by . Let the set of edges dual to  in be . By abuse of notation, we also denote by  the graph formed by contracting all the edges in . Since each face of  encloses a terminal, each bounded face of  must enclose an attachment point of the honeycomb. If not, then we could remove from  an edge in  dual to some edge of the face of  not enclosing an attachment point. This does not make any new terminal-to-terminal connections, as the part of the honeycomb enclosed by this face does not contain any path to any of the terminals of . This would be a contradiction to the minimality of .\nNext, we observe that no bounded face of  can enclose more than one attachment point. Suppose that there exists a bounded face in  that encloses two attachment points. Since the two attachment points are separated by 100 cells of the honeycomb, the length of the face boundary must be at least 50. We could remove all the 50 edges from  dual to the edges of the face boundary and add all the attaching edges to , instead. All the terminal-to-terminal paths passing through the honeycomb will remain disconnected after the transformation. Since at most eight attaching edges can be added, we again get a contradiction to the minimality of . So, each bounded face of  must enclose exactly one attachment point.\nTo enclose the attachment points, each of these faces must cross the boundary of the honeycomb exactly twice. We claim that the faces of , enclosing consecutive attachment points on the boundary of the honeycomb, are pairwise edge-disjoint. Suppose that the faces enclosing two consecutive attachment points,  and , share an edge. Then, they must also share an edge that crosses the boundary of the honeycomb. If they do not, then let  be the last edge of the face enclosing  to cross the boundary and  be the first edge of the face enclosing  to cross the boundary of the honeycomb. The edges  and  along with the other edges not shared between the respective face boundaries bound a region of the plane containing no attachment points, a contradiction!\nTherefore, any two faces of  enclosing consecutive attachment points share an edge which crosses the boundary of the honeycomb. Without loss of generality, let this edge be closer to . Then, the face enclosing  must contain at least 50 edges as  and  are separated by 100 cells of the honeycomb. This implies that  contains at least 50 edges. However, we could remove from it all the 50 edges and add all the (at most eight) attaching edges. This cut is smaller in size and disconnects all the terminal-terminal paths passing through the honeycomb. Once again, we contradict the minimality of .\nHence, all the faces in  enclosing attachment points are edge-disjoint. So, there are at least  edges in . We could replace this cut by a smaller cut, namely, the edge multiway cut formed by removing the edges in  from  and adding to it all the attaching edges incident on the attachment points. This cut disconnects all terminal-paths passing through the honeycomb and yet, is smaller in size than , a contradiction to its minimality. Hence,  does not contain any edge of any of the honeycombs.\nBy the construction of  and Claims 1  ###reference_1###, 7  ###reference_7###, and 8  ###reference_8###, we conclude that Edge Multiway Cut is NP-complete on planar subcubic graphs."

Therefore, if an edge in the edge multiway cut of  is incident on a terminal, we can replace it with its adjacent edge, which disconnects all the paths disconnected by the former and does not increase the size of the edge multiway cut.

(2021  ###reference_b16###). Recently, anomaly detection techniques based on\nDeep Learning (DL) models, such as Long Short-Term Memory\n(LSTM) Du et al. (2017  ###reference_b9###); Meng et al. (2019  ###reference_b31###); Zhang et al. (2019  ###reference_b52###) and Convolutional\nNeural Networks (CNNs) Lu et al. (2018  ###reference_b29###), have shown promising results.\nOne common aspect of most anomaly detection techniques is having a\npre-processing step called log parsing (also known as log template\nidentification). This step is needed because anomaly detection techniques require structured\nlogs to automatically process them, whereas input logs are often free-formed or\nsemi-structured, as generated by logging statements (e.g., printf()\nand logger.info()) in the source code. Many log parsing\ntechniques have also been developed to automatically convert unstructured input\nlogs into structured logs Zhu et al. (2019  ###reference_b53###).\nThe frequent combination of log parsing and anomaly detection clearly implies the\nimportance of the former for the latter. Nevertheless,\nassessing in a systematic way the\nimpact of log parsing on anomaly detection has received surprisingly little\nattention so far. Only\nrecently, Shin et al. (2021  ###reference_b44###) investigated what ideal log parsing results\nare in terms of accurate anomaly detection, but purely from a theoretical standpoint.\nLe and Zhang (2022  ###reference_b27###) empirically showed that different log parsing techniques,\namong other potential factors, can significantly affect anomaly detection\naccuracy, but the accuracy of log parsing results was not adequately measured, and\nthe correlation between log parsing accuracy and anomaly detection accuracy\nwas not reported.  Fu et al. (2023  ###reference_b12###) attempted to address the issue by evaluating log parsing and anomaly detection accuracy. However, they relied on a single log parsing accuracy metric Khan et al. (2022  ###reference_b24###), and the log parsing results used to evaluate anomaly detection techniques were based on less than 1% of all logs used, which limits the validity of the findings.\nTo systematically investigate the impact of log parsing on anomaly detection\nwhile addressing the issues of the aforementioned studies, this paper\nreports on an empirical study, in which we performed a\ncomprehensive evaluation using 13 log parsing techniques,  seven anomaly detection\ntechniques\u2014five based on deep learning and two based on traditional machine learning\u2014on  three publicly available log datasets. We considered all three log\nparsing accuracy metrics (i.e., grouping accuracy Zhu et al. (2019  ###reference_b53###), parsing\naccuracy Dai et al. (2020  ###reference_b6###), and template accuracy Khan et al. (2022  ###reference_b24###))\nproposed in the literature.\nAgainst all assumptions, our results show that there is no strong correlation between log\nparsing accuracy and anomaly detection accuracy, regardless of\nthe metric used for measuring log parsing accuracy. In other words,\naccurate log parsing results do not necessarily increase anomaly detection\naccuracy. To better understand the phenomenon at play,\nwe investigated another property of log parsing, distinguishability,\na concept proposed by Shin et al. (2021  ###reference_b44###) that was theoretically shown\nto relate to anomaly detection accuracy. Our empirical results confirm that,\nas far as anomaly detection is concerned,\ndistinguishability in log parsing results is the property\nthat really matters and should be the key target of log parsing.\nIn summary, the main contributions of this paper are:\nthe systematic and comprehensive evaluation of the impact of log parsing\non anomaly detection;\nthe investigation of the impact of the distinguishability of log parsing\nresults on anomaly detection.\nThe rest of the paper is organized as follows. Section 2  ###reference_###\nprovides basic information used throughout the paper, including the definitions\nof logs, messages, and templates, as well as an overview of log parsing and\nanomaly detection.

This leads to the problem of log parsing (log template identification):\nHow can we identify the log templates of log messages without accessing the source code?\nTo address this problem, many automated log-parsing approaches,\nwhich take as input log messages and identify their log templates using different\nheuristics, have been proposed in the literature (e.g., AEL Jiang et al. (2008  ###reference_b21###),\nDrain He et al. (2017  ###reference_b14###), IPLoM Makanju et al. (2009  ###reference_b30###),\nLenMa Shima (2016  ###reference_b43###), LFA Nagappan and Vouk (2010  ###reference_b36###),\nLogCluster Vaarandi and Pihelgas (2015  ###reference_b48###), LogMine Hamooni et al.

(2019  ###reference_b53###), Parsing\nAccuracy (PA) Dai et al. (2020  ###reference_b6###), and Template Accuracy\n(TA) Khan et al. (2022  ###reference_b24###).\nZhu et al. (2019  ###reference_b53###) observed that log parsing can be considered as a clustering\nprocess where log messages with the same template are clustered into the same\ngroup. Based on this idea, they proposed the GA metric to assess if log messages\nare correctly grouped. Specifically, GA is defined as the ratio of log messages\ncorrectly parsed by the log parsing approach under evaluation over the\ntotal number of log messages, where a log message is correctly parsed when its\nlog message group is the same as the ground truth (i.e., a group generated by\noracle templates).\nDai et al. (2020  ###reference_b6###) later proposed PA, to address the issue that GA only considers\nmessage groups, not the equivalence between the templates identified by the log\nparsing approach under evaluation and the oracle templates. Although having\ncorrectly grouped messages would be enough in some cases (e.g., detecting\nanomalies based on the sequence of template IDs without considering the content\nof the templates Du et al. (2017  ###reference_b9###)), correctly identified templates (i.e.,\ntemplates identical to the corresponding oracle ones) matter when the fixed parts of\ntemplates are used (e.g., detecting anomalies based on the semantic information\nin the templates Zhang et al. (2019  ###reference_b52###)). To this end, PA replaces the\ndefinition of a correctly parsed log message in GA as follows: a log message is\ncorrectly parsed when its identified template is identical to the\noracle template.\nKhan et al. (2022  ###reference_b24###) recently proposed the TA metric, since both GA and PA are\ndefined based on the number of correctly parsed log messages and, therefore, can\nbe misleading, especially when there are many repeated messages (e.g., heartbeat\nmessages). Specifically, they introduced Precision-TA (PTA) and Recall-TA (RTA),\nwhere PTA is defined as the number of correctly identified templates over the\ntotal number of identified templates and RTA is defined as the number of\ncorrectly identified templates over the total number of oracle templates.\nMoreover, FTA (short for \u201cF1-measure TA\u201d) is the harmonic mean of PTA and RTA."

(2021  ###reference_b44###).\nLe and Zhang (2022  ###reference_b27###) recently presented an empirical work\ninvestigating several aspects that can impact Deep Learning (DL)-based\nanomaly detection approaches, such as\ntraining data selection, data grouping, class distribution, data noise, and early detection ability.\nOne of their experiments considering data noise assessed the impact of noise deriving\nfrom log parsing results. Specifically, they used four log parsing techniques (Drain He et al. (2017  ###reference_b14###),\nSpell Du and Li (2016  ###reference_b8###), AEL Jiang et al. (2008  ###reference_b21###), and IPLoM Makanju et al. (2009  ###reference_b30###))\nto generate log parsing results for two log datasets (BGL Oliner and Stearley (2007  ###reference_b38###) and\nSpirit Oliner and Stearley (2007  ###reference_b38###)).\nThen, for each log dataset, they used the different log parsing\nresults as input of five anomaly detection approaches (DeepLog Du et al. (2017  ###reference_b9###), LogAnomaly Meng et al. (2019  ###reference_b31###),\nPLELog Yang et al. (2021  ###reference_b51###), LogRobust Zhang et al. (2019  ###reference_b52###), and\nCNN Lu et al. (2018  ###reference_b29###)), and measured the accuracy of the latter.\nTheir experimental results showed that log parsing approaches highly influence\nthe accuracy of anomaly detection;\nfor example, the F1-Score of DeepLog on Spirit logs Oliner and Stearley (2007  ###reference_b38###)\ndecreases from  to  when Drain is used instead of IPLoM for log parsing.\nAlthough this is the first clear evidence showing the impact of log parsing\nresults on anomaly detection accuracy, the scope of the underlying\nstudy is limited. For example, it simply uses different log parsing\nresults (produced by different tools)\nwithout quantitatively assessing the accuracy of the log parsing tools;\ntherefore, the relationship between log parsing accuracy and anomaly detection accuracy remains unclear.\nTo this end, we define our first research question as follows:\nRQ1 - To which extent does the accuracy of log parsing affect the accuracy of anomaly detection?\nAs summarized in Section 2.4  ###reference_###, Shin et al. (2021  ###reference_b44###) recently proposed a theoretical\nframework determining the ideal log parsing results for anomaly\ndetection by introducing the concept of \u201cdistinguishability\u201d for\nlog parsing results. It is argued that, rather than accuracy as previously assumed, what really matters is the extent to which log parsing results are distinguishable.\nHowever, to the best of our knowledge, there is no empirical work\nassessing quantitatively distinguishability in log parsing results\nand its impact on anomaly detection accuracy.\nTherefore, we define our second research question as follows:\nRQ2 - How does the\naccuracy of anomaly detection vary with distinguishability of log parsing\nresults?\nAnswering the above questions will have a significant impact on both research\nand industry in the field of log-based anomaly detection. For example, if the\nanswer to the first question is that, regardless of the log parsing accuracy\nmetrics, there is no relationship between log parsing accuracy and anomaly\ndetection accuracy, then it means that there is no need to use the existing\naccuracy metrics to evaluate log parsing results for anomaly detection. This\nwould completely change the way log parsing tools are evaluated. Similarly, if\nthe answer to the second question is that the distinguishability of log parsing\nresults indeed affects anomaly detection, as expected from the recent\ntheoretical analysis Shin et al. (2021  ###reference_b44###), then this must be the focus of log parsing evaluations. As a result, our answers will\nprovide essential insights on better assessing the quality of log parsing techniques\nfor more accurate anomaly detection."

As discussed by Khan et al. (2022  ###reference_b24###), those manually generated oracle\ntemplates are error-prone; therefore, we used the logging statements in the source code to extract\ncorrect oracle templates.\nTable 1  ###reference_### shows all the log datasets in the LogHub benchmark\nand whether they meet each of the above-mentioned criteria; the rows\nhighlighted in gray meet both criteria.\nDuring our preliminary evaluation, we found an issue with HDFS.\nThe original HDFS logs were too large  ( log messages) to be processed by the\nslowest anomaly detection technique (i.e.,\nLogAnomaly Meng et al.

Specifically, the original HDFS dataset consists of  log messages, with 97.43% normal and 2.57% abnormal log messages, and the reduced HDFS dataset mirrors this distribution, with 97.60% normal and 2.40% abnormal log messages.\n###table_2### Table 2  ###reference_### reports on the size of our\ndatasets, in terms of the number of oracle templates (O), the\nnumber of all logs (), the number of normal logs (), the number of abnormal logs (), the number of all messages (), the number of messages in normal logs (), and the number of messages in abnormal logs ().

This means that increasing log\nparsing accuracy does not necessarily increase (or decrease) anomaly detection accuracy.\nThis is counter-intuitive since anomaly detection uses log parsing results, and\nhaving \u201cbetter\u201d log parsing results is expected to increase anomaly detection\naccuracy. However, this happens because even inaccurate log parsing results can\nlead to accurate anomaly detection results, for reasons explained below.\nTo better understand the reason for the above results,\nlet us consider the following two extreme cases separately:\nThe log parsing accuracy values for input logs are the same,\nbut the resulting anomaly detection accuracy values are different\n(i.e., the data points located on the same vertical lines in\nFigure 2  ###reference_### and Figure 3  ###reference_###).\nThe log parsing accuracy values for input logs are different,\nbut the resulting anomaly detection accuracy values are the same\n(i.e., the data points located on the same horizontal lines in\nFigure 2  ###reference_### and Figure 3  ###reference_###).\nTo identify the root cause of C1, we manually investigated several pairs of data points in\nFigure 2  ###reference_### and Figure 3  ###reference_###,\nsuch as two different HDFS log parsing results having almost the same log parsing accuracy value\n(GA scores of 0.37 and 0.40) but resulting in significantly different anomaly detection accuracy values\n(F1 scores of 0.73 and 0.10) for the same anomaly detection technique (DeepLog).\nIt turned out that, although the log parsing accuracy values are similar,\n the sets of correctly parsed log messages are different.\nThis happened because the log parsing accuracy metrics (GA, PA, and FTA) summarize\nthe log parsing results based on an implicit assumption that\nall log messages (and templates) are equally important.\nHowever, this assumption does not hold when it comes to anomaly detection,\nwhich must discriminate different log message templates to learn abnormal sequences of templates.\nTherefore, this mismatch of assumptions between log parsing and anomaly detection leads to case C1.\nAs for case C2, similar to the above case,\nwe manually investigated several pairs of data points in\nFigure 2  ###reference_### and Figure 3  ###reference_###,\nsuch as two different Hadoop log parsing results having significantly different log parsing\naccuracy values (GA scores of 0.12 and 0.77) but resulting in the same anomaly detection value\n(F1 score of 0.98) for the same anomaly detection technique (DeepLog).\nWe found that anomaly detection techniques can distinguish between normal and abnormal patterns\neven when input log message templates are incorrect.\nTo best explain this using a simplified example, let us consider a normal log\n and an abnormal log , where  indicates the -th log message in\n for . Using oracle templates, we can group the log messages\nhaving the same template and represent  and  as groups;\nspecifically, let  be a sequence of\nmessage group indices (i.e., the -th element of  is\nthe message group index of ).\nIn this context, let us take two logs from\nthe Hadoop dataset as a concrete example where\n and\n.\nWhen templates generated by LogMine are used to group\nmessages instead of oracle templates, the sequences of message group indices\nchange to \nand .\nThese are clearly different from  and , respectively;\nin particular,  and  are incorrectly grouped together in \nwhile , , and  are incorrectly separated in .\nThe incorrect groupings of LogMine clearly reduce the GA score (as well as PA and TA\nscores since incorrect groupings\nimply incorrect templates). However, even the incorrect  and\n are still different enough from each other for anomaly detection techniques to distinguish between normal and abnormal patterns.\nThis example not only shows why case C2 happened,\nbut also demonstrates the importance of distinguishability in log parsing results for anomaly\ndetection; we will further investigate this aspect in RQ2.\nBefore we conclude RQ1, one might be curious to know why DeepLog, LogAnomaly, LogRobust,\nand CNN result in the same anomaly detection accuracy value on the Hadoop\ndataset (as shown in Figure 3  ###reference_### [GA-Hadoop] and\nTable 3  ###reference_###). This happens because (1) the\ntest set of Hadoop contains only 11 logs (1 normal and 10 abnormal logs,\nalthough the number of log messages is in the same order of magnitude as HDFS;\nsee Table 2  ###reference_### for more details) and (2)\nthe four anomaly detection techniques classified all the 11 logs in the test set as\nabnormal. We speculate that PLELog shows different results from the other anomaly\ndetection techniques because PLELog uses a very different deep learning model (i.e., an\nattention-based GRU Cho et al. (2014  ###reference_b5###)). Notice that, in all\ncases, the results still corroborate that log parsing accuracy and anomaly detection accuracy do not\nhave any strong relationship.\nWe want to note that the log parsing accuracy results shown in\nFigure 2  ###reference_### and Figure 3  ###reference_###\nare inconsistent with the ones reported in previous studies Zhu et al. (2019  ###reference_b53###); Dai et al. (2020  ###reference_b6###)\nsince the latter only considered 2K log messages, randomly sampled from the original logs,\nto assess log parsing accuracy."

As explained with an example in\nSection 5.1  ###reference_###, this happens because inaccurate log parsing\nresults can still be useful for anomaly detection as long as normal and abnormal\nlogs are distinguishable. At the extreme, a log parsing result  with\n50% accuracy could be better for anomaly detection than a log parsing result\n with 100% accuracy if  distinguishes normal and abnormal logs\nwhile  does not.\n This could happen when, for example, the log quality is poor\n(e.g., because of inconsistencies between the developers\u2019 intentions and concerns on logging\nand the actual logging statements in the source code Rong et al.

Instead, as shown in Section 5.2  ###reference_###,\nthe distinguishability of log parsing results should be the main selection criterion. For\nexample, since normal and abnormal logs are often used for training anomaly detection\nmodels, candidate log parsing results should be compared in terms of their\ncapability to distinguish normal and abnormal logs. If there are multiple\ntechniques that can equally distinguish between normal and abnormal logs, then the one\nwith the lowest number of identified templates would be preferred since reducing\nthe number of templates would increase the performance of anomaly detection by\nreducing dimensionality (i.e., the number of features considered in machine\nlearning models) Shin et al. (2021  ###reference_b44###).\nNote that the notion of distinguishability for log parsing results is irrelevant if these results are not used for anomaly detection.\nHowever, if anomaly detection needs log parsing (which is frequently the case in practice), then considering distinguishability can help engineers select the most suitable log parsing technique for anomaly detection.\nOne may rightfully think that it is intuitive that the distinguishability of log parsing\nresults is essential for learning-based anomaly detection techniques,\nwhich distinguish between normal and\nabnormal log sequences by using the log parsing results (i.e., templates) as learning\nfeatures.

(2019  ###reference_b53###); Dai et al. (2020  ###reference_b6###); Khan et al. (2022  ###reference_b24###) were conducted\nover the last four years.\nSimilarly, the relationship between log parsing and anomaly detection has\nreceived little attention until very recently. Below, we summarize the recent\nstudies related to this topic.\nShin et al. (2021  ###reference_b44###) presented the first theoretical study considering\nthe relationship between log parsing and anomaly detection. As described in\nSection 2.4  ###reference_###, they established the concept of ideal log\nparsing results for anomaly detection. We adopted their theoretical foundation,\nespecially the notion of distinguishability in log parsing results, and\nempirically showed that distinguishability is indeed essential for anomaly detection. To the best of our knowledge, our work is the\nfirst empirical study showing the importance of log parsing distinguishability for anomaly detection.\nAs explained in Section 3  ###reference_###, Le and Zhang (2022  ###reference_b27###) presented an empirical study on factors that could affect\nanomaly detection accuracy.\nAlthough a part of their study investigated the impact of log parsing on anomaly\ndetection accuracy, they investigated four log parsing techniques but did not\nassess the impact of log parsing accuracy. As a result, they only showed that using\ndifferent log parsing techniques leads to different anomaly detection\naccuracy scores. In our\nstudy, on the other hand, we explicitly measured log parsing accuracy, collected\n160 pairs of log parsing accuracy and anomaly detection accuracy values using\ndifferent combinations of log parsing and anomaly detection techniques, and showed that there is\nno strong correlation between log parsing accuracy and anomaly detection\naccuracy.\nDuring the writing of this paper, Fu et al. (2023  ###reference_b12###) also presented an\nempirical study on the impact of log parsing on anomaly detection performance.\nAlthough their motivation and research questions are close to ours, there are\nseveral key differences.\nFirst, for measuring log parsing accuracy, they used the manually generated,\nerror-prone oracle templates Khan et al. (2022  ###reference_b24###) provided with the 2K log\nmessages randomly sampled by Zhu et al. (2019  ###reference_b53###). In other words, only a very\nsmall fraction of the logs used for anomaly detection was used to measure log\nparsing accuracy in their study. In our study, however, the same logs used for\nanomaly detection are used to measure log parsing accuracy, and the oracle\ntemplates are directly extracted from the corresponding source code.\nSecond, they considered only one log parsing accuracy metric (GA), whereas we\nconsidered all three log parsing metrics (GA, PA, and TA) since different metrics assess complementary aspects of log\nparsing Khan et al. (2022  ###reference_b24###).\nThird, log parsing distinguishability, which is an essential factor that substantially affects\nanomaly detection accuracy (as shown in our RQ2), is only considered\nin our study.\nFinally, they only considered two deep learning-based anomaly\ndetection techniques (DeepLog and LogRobust), and focused also on more\ntraditional machine learning approaches (such as Principal Component\nAnalysis, clustering, logistic regression, and decision trees).\nSuch differences allow us to report new findings and provide concrete recommendations, as\nsummarized in Section 6  ###reference_###.\nWu et al. (2023  ###reference_b50###) recently presented an empirical study\non the effectiveness of log representation for machine learning-based\nanomaly detection. They considered different log representation\ntechniques, such as FastText Joulin et al. (2016  ###reference_b22###), Word2Vec Mikolov et al. (2013  ###reference_b33###),\nTF-IDF Salton and Buckley (1988  ###reference_b42###) and\nBERT Devlin et al. (2018  ###reference_b7###), used to convert textual log data into\nnumerical feature vectors for machine learning algorithms, such as\nSupport Vector Machine, Logistic Regression, Random Forest,\nCNN, and LSTM. As a part of their study, they investigated\nthe impact of log parsing on anomaly detection\nwhen used with different log representation techniques\n(in particular, FastText and Word2Vec).\nThe empirical results showed that, in general,\nusing log parsing (i.e., Drain He et al. (2017  ###reference_b14###)) improves the quality of log\nrepresentations (over raw, unparsed data) and thereby the performance\nof anomaly detection; they also reported that some models (e.g., CNN\nand LSTM) are less sensitive to whether the log data is parsed or not, possibly due\nto the strong feature extraction and representation ability, and can offset the impact of\nnoise generated by log parsing.\nIn addition to these results, they also investigated\nthe impact of additionally refining log parsing results using regular expressions\nand the impact of using different log parsing techniques.\nThe results showed that refining log parsing results do not significantly increase\nanomaly detection performance but using different log parsing techniques yields\nslight variations in anomaly detection performance.\nHowever, for these additional investigations, they used only one anomaly\ndetection technique (i.e., Logistic Regression) and two log parsing techniques\n(i.e., Drain He et al. (2017  ###reference_b14###) and LogPPT Le and Zhang (2023  ###reference_b28###)).\nFurthermore, they did not study the relationship between\nlog parsing accuracy and anomaly detection accuracy. On the contrary,\nwe use 13 log parsing techniques and 5 DL-based anomaly detection techniques\nto comprehensively investigate the relationship between log parsing accuracy\nand anomaly detection accuracy.\nTable 8  ###reference_### summarizes the key differences between\nthe closely-related previous empirical studies (i.e., Le and Zhang (2022  ###reference_b27###), Fu et al.

+    "abstract": "This paper proposes a general and practical approach to estimate the economic benefits of optimally controlling deferrable loads in a Distribution System Operator\u2019s (DSO) grid, without relying on historical observations. We achieve this by learning the simulated response of flexible loads to random control signals, using a non-parametric global forecasting model. An optimal control policy is found by including the latter in an optimization problem. We apply this method to electric water heaters and heat pumps operated through ripple control and show how flexibility, including rebound effects, can be characterized and controlled. Finally, we show that the forecaster\u2019s accuracy is sufficient to completely bypass the simulations and directly use the forecaster to estimate the economic benefit of flexibility control.",

+            "text": "Flexibility is a term used to describe the ability of electric loads or distributed energy resources (DERs) to shift their consumption or production in time. Flexibility in distribution or transmission grids can increase grid resilience, reduce maintenance costs, lower distribution losses, and smooth and increase the predictability of the demand profile [1  ###reference_b1###, 2  ###reference_b2###, 3  ###reference_b3###]. Flexibility services usually require aggregating flexible residential customers into pools that reach a given \u201dcritical mass\u201d [4  ###reference_b4###, 5  ###reference_b5###]. In most cases, aggregation requires controlling heterogeneous types of devices [6  ###reference_b6###] (e.g., heat pumps, electric boilers, EVs, PVs), running different types of onboard controllers, (e.g., rule or heuristic-based, model predictive control, etc..). This condition restricts the kind of viable control methods for pooling flexibility. Some protocols, such as OSCP [7  ###reference_b7###], envisage intermediate actors optimizing flexibility pools by means of a global control signal, delegating the complexity of low-level control to a flexibility provider [8  ###reference_b8###, 9  ###reference_b9###]. Currently, the most used control method is ripple control [10  ###reference_b10###], using frequency-sensitive relays to shut down flexible devices. Aggregating loads in control pools reduces uncertainty in the total amount of actuated flexibility [11  ###reference_b11###]; yet, communicating instant flexibility may prove insufficient for optimal dispatch. Frequently, deactivating a cluster of energy-intensive devices might trigger a \u201drebound effect\u201d in the overall load once they are reactivated [12  ###reference_b12###]. This effect can create an unintended spike in peak demand, a factor that should be taken into account when optimizing the overall power profile."

+            "text": "Flexibility research has gained prominence in recent publications. For example, the International Energy Agency\u2019s (IEA) Annex 67 [13  ###reference_b13###] focuses on using building flexibility for grid control, and Annex 82 [14  ###reference_b14###] examines its quantification for utilities and DSOs. Some publications are mostly focused on the characterization of flexible devices [15  ###reference_b15###, 16  ###reference_b16###, 17  ###reference_b17###, 18  ###reference_b18###, 19  ###reference_b19###] while others mostly explore its exploitation in the context of demand side management and demand response, under the hypothesis of a known, observable and directly controllable system [20  ###reference_b20###, 21  ###reference_b21###, 22  ###reference_b22###]. For example, in [22  ###reference_b22###], [21  ###reference_b21###] and [23  ###reference_b23###], this is achieved for thermally activated building system (TABS) and heat pumps (HPs).\nOur work is mostly related to simulation-based flexibility assessment of partially observable and indirectly controllable systems. This setting resembles the current operational conditions of electrical grids: DSOs usually can only rely on smart meters\u2019 relays for load actuation, and temperature readings are not available. Similar conditions were considered in [24  ###reference_b24###], where authors assessed the energy flexibility potential of a pool of residential smart-grid-ready HPs (i.e., with an internal controller reacting to a discrete signal indicating if they have to consume more, less, or shut down) by means of bottom-up simulations. Similarly, in [25  ###reference_b25###], authors predicted the energy consumption of a group of 300 HPs controlled via binary throttling signals. In [26  ###reference_b26###], the authors trained a forecaster on periods in which demand-response is not active to quantify the flexibility associated with a pool of customers under a price-and-volume schema. This approach was possible due to the sparsity of actuation events, allowing to separate baseline and activation periods. Our work is also related to inverse optimization of price signals, which was first introduced in [27  ###reference_b27###]. The idea is that assuming that some buildings use a price-dependent (but unknown) controller, the DSO or an aggregator can try to reverse engineer the controllers by estimating approximate and invertible control laws by probing the system with a changing price signal; since the learned control laws are invertible, they can then be used to craft the optimal cost signal to provide a desired aggregate power profile. To show this, authors in [27  ###reference_b27###] fitted an invertible online FIR model to forecast the consumption of a group of buildings as a function of a price signal and derive an analytic solution for an associated closed-loop controller. The concept was then demonstrated by means of simulations on 20 heat-pump-equipped households. The authors of [18  ###reference_b18###] used the same concept to fit a linear model linking prices and the load of a cluster of price-sensitive buildings. The authors then proposed to characterize flexibility extracting parameters from the model response. They also proposed to estimate the expected savings of a given building by simulating its model twice, with and without a price-reacting control. A similar approach was proposed in [28  ###reference_b28###], where authors identified a general stochastic nonlinear model for predicting energy flexibility coming from a water tower operated by an unknown control strategy. The fitted model is then used in an optimization loop to design price signals for the optimal exploitation of flexibility. Authors in [29  ###reference_b29###] used the same method to find price signals to best meet flexibility requests using an iterative method."

This allows conditioning the response on categorical variables, such as the number of controlled devices of different types and past binary control signals generated by ripple control or throttling. This latter ability allows the use of the forecaster as a surrogate model of the simulation inside a control loop. We also show that global models provide sufficient accuracy to bypass the simulations and to perform the same kind of what-if analysis presented in [24  ###reference_b24###]. This is possible because we are only interested in the aggregated power of the controlled devices, which has a much lower dimensionality than all the simulated states and signals. The method we propose can be used to assess the power response of groups of flexible devices from day zero by means of simulations but can also be applied to real controlled systems (for which it is not possible to retrieve a baseline response) by augmenting the training set using observations from the field. In section II  ###reference_###, we show that the modeling and simulation phase needed to create a training set for the metamodel only requires statistical information, which is usually publicly available. In section III  ###reference_###, we present a method to predict energy flexibility using a global forecasting model. We conduct an ablation study in which we suggest various training methodologies. These findings indicate that incorporating concepts of energy imbalances throughout the prediction horizon and crafting a training set from scenarios exhibiting orthogonal penetrations based on device types enhances the accuracy of forecasts. In III-D  ###reference_###, we use the metamodel to characterize flexibility and rebound effects, allowing us to answer complex questions like: How does the controlled device mix influence flexibility? And, how many kWh, at which power level, could be deferred? In section IV  ###reference_###, we describe how the metamodel can be used to optimize the available flexibility. In section IV-B  ###reference_###, we propose a dynamic grouping strategy to ensure that the thermal comfort constraints of end users with an HP are never violated.

Furthermore, training a single tree for the whole dataset requires more computational time than training a set of MISO predictors in parallel (on a dataset that is 96 times smaller).

In the second strategy, the number of the two controllable classes of devices is increased independently, co-varying the number of HPs and EHs in a cartesian fashion.\n###figure_2### To enhance the accuracy of the metamodel, a physics-informed approach involving energy imbalance is proposed. This method utilizes the metamodel to simulate the system\u2019s response under two conditions: with the actual control signal  and with a zeroed control signal. By subtracting these responses, we quantify the system\u2019s \u2019energy debt\u2019 at each timestep. This physics-based insight is crucial for improving predictions of future states. To test this hypothesis, we developed a secondary model where a set of regressors first forecasts the system response for future steps under both scenarios. The resultant energy imbalances from these predictions serve to enrich the training dataset. Subsequently, another set of regressors is trained on this augmented dataset, employing this physics-informed strategy during both training and prediction phases.\nIn total, we compared four distinctive configurations, comprising the two models and the two sampling strategies. Figure 3  ###reference_### provides representative examples of predictions of the energy-aware metamodel trained using the grid sampling strategy, featuring varying counts of controlled heat pumps (HPs) and electric heaters.\n###figure_3### Models performances can be better compared when plotting the average (over samples and prediction times) normalized Mean Absolute Error (nMAE) as a function of step ahead, as done in figure 4  ###reference_###. The nMAE for the predictions generated at time  is defined as:\nThe grid sampling scheme did indeed help in increasing the accuracy of the predictions w.r.t. the random sampling scheme for both the LightGBM models. Including the information about energy imbalances at each step ahead shows some benefits for both sampling strategies, at the expense of a more complex model. The accuracy improvement impacts only controlled scenarios, as demonstrated by comparing the second and third panels in figure 4  ###reference_###. These panels show the scores obtained for instances where the force-off signal was activated at least once or never activated. This result aligns with our expectations. As an additional analysis, we studied the energy imbalance over the prediction horizon. For this analysis, we considered just the controlled cases in the test set. We define two relative energy imbalanced measures:\nwhere  is the simulated power,  is the power predicted by the metamodel with the control used in the simulation, and  is the power predicted by the metamodel using a zero force off. We can interpret  as the relative error in the total energy needs w.r.t. the simulation and  as the change in the energy consumption estimated by the metamodel if the pool of flexible devices were not controlled. We removed from the comparison all the instances in which the force-off signal was activated in the last 5 hours of the day. In this case, part of the consumption will be deferred outside the prediction horizon, making the comparison meaningless.\nLooking at the first row of figure 5  ###reference_###, we see how the empirical cumulative distribution functions (ECDFs) of  and its absolute value (left and right panels) are closer to zero when the grid sampling strategy is applied. Also, using the energy-aware model helps in having a more precise prediction in terms of used energy over the prediction horizon. For all 4 models, 80 % of the time, the relative deviation in the horizon energy prediction lies below 20%. The second row of figure 5  ###reference_### reports the change in the forecasted energy consumption within the prediction horizon with and without control. It is reasonable to think that the consumption should approximately match since the force off usually just defers the consumption. In this case, the energy-aware models present a lower difference in the consumed energy.\n###figure_4### ###figure_5###"

Figure 6  ###reference_### shows three extreme examples of the characterization: the penetration scenario with the maximum number of EHs and zero HPs, the converse, and the scenario where both penetrations are at their maximum value. The rebound is shown in terms of energy imbalance from the test set, such that they have a force-off signal turning off at the fifteenth plotted step. It can be noticed how different observations can start to show negative energy imbalance at different time steps; this is because force-off signals can have different lengths, as shown in figure 1  ###reference_###. The upper left quadrant shows the energy imbalance predicted by the metamodel in the case of the maximum number of EHs and no HPs. Comparing it with the lower right quadrant, where the sample just contains HPs, we see that the rebound effect has a quicker decay, being close to zero after only 10 steps (corresponding to 2 and a half hours). The lower right quadrant exhibits a markedly slower dissipation of the rebound effect, attributable to the different heating mechanisms and temporal constants inherent in systems heated by EHs and HPs. EHs, dedicated solely to DHW heating, have their activation guided by a hysteresis function governed by two temperature sensors installed at varying heights within the water tank. In contrast, HPs are responsible for both DHW and space heating, and their activation hinges on the temperature of the hydronic circuit, thus creating a segregation between the HPs and the building heating elements, namely the serpentine. As a result, HPs\u2019 activation is subject to a system possessing a heating capacity significantly greater than that of the standalone DHW tank: the building\u2019s heating system. Further intricacy is added to the power response profile of the heat pump due to its dual role in catering to DHW and space heating needs, with priority assigned to the former. The visual responses presented in Figure 1  ###reference_### are color-differentiated according to the seven-day mean of the ambient temperature. As per the expected pattern, the EHs\u2019 responses exhibit independence from the average external temperature, while a modest influence can be detected for the HPs, where a rise in average temperatures aligns with a faster decay in response.\n###figure_6###"

The objective that we found most compelling from both the DSO and energy supplier perspectives is the simultaneous minimization of day-ahead costs (incurred by the energy supplier on the spot market) and peak tariff (paid by the DSO to the TSO). Notably, this scenario is particularly well-suited to Switzerland, where a distinctive situation persists with the energy supplier and the DSO remaining bundled. The peak tariff, being proportionate to the maximum monthly peak over a 15-minute interval, poses a more significant optimization challenge than day-ahead costs, as the peak tariff is paid on the monthly peak. Since it is extremely hard to produce accurate forecasts over a one-month period, we solved the peak shaving problem on a daily basis as a heuristic. This then leads us to the following optimization problem:\nwhere  refers to the step ahead,  is the day-ahead spot price,  is the price for the monthly peak in ,  is a coefficient taking into account the timestep duration.

This is especially true in the context of heat pumps, as variations in building insulation and heating system sizing inevitably lead to differences in turn-on requirements to maintain home thermal comfort under identical weather conditions. Analogous considerations apply to hot water boilers as well. In addition, it is crucial to note that, generally, EHs can endure longer force-off periods than HPs.

This correlation can be effectively illustrated using an equivalent linear RC circuit to model the building\u2019s thermal dynamics.\nThe static behavior of this model can be represented by the energy signature, which depicts the linear relationship between the building\u2019s daily energy consumption and the mean daily external temperature, denoted as .

A more significant comparison is in terms of economic returns. We compared these approaches:\nSimulated: we run the optimization and fully simulate the system\u2019s response. In this setting, the metamodel is just used to obtain the optimal control signal to be applied the day ahead. The controlled devices are then simulated, subject to the optimal control signal.

We have a comparable deviation for forecasts and closed-loop simulations. In all the cases, the peak costs are underestimated; this was to be expected, as the metamodel is trained with a sum of squares loss, which systematically underestimates extreme events.

We achieved this by training a non-parametric global forecasting model conditional to the control signals and the number of controlled devices to predict their simulated aggregated power. The numerical use case showed that the forecaster\u2019s accuracy is high enough to use it as a guide to optimally steer deferrable devices. Moreover, the high accuracy on economic KPIs suggests that the forecaster can be used to completely bypass the simulation and speed up A/B-like testing and the retrieval of different demand-side management policies over different penetration of devices.\nWe envision the following possible extensions of the presented work:\nContinuous control. The presented use case relied on extensive enumeration of the possible force-off signals for the day ahead optimization. This was possible due to restrictions requested by the DSO on the shape of the control signal, which resulted in a total number of possible control signals in the order of 1e5 scenarios. Using a higher timestep for the control will require evaluating a prohibitive number of scenarios. The approach proposed in this paper can still be feasible by replacing the boosted tree with an \u201doptimizable\u201d regressor, that is, either a partial input-convex neural network [33  ###reference_b33###] or a conditional invertible neural network [34  ###reference_b34###]. In this case, we can use a continuous signal  indicating the fraction of flexible devices to be forced off at a given moment in time. We can then apply gradient descent to the optimizable regressor and retrieve the optimal .\nProbabilistic forecast. The presented optimization framework is based on a deterministic formulation. Formulating the problem in the stochastic framework could be advantageous when considering peak tariffs. This would require summing two sources of uncertainty: the one associated with the prediction of the total power profile  and the one associated with the metamodel forecasts. These can be both assessed by obtaining probability distributions after the training phase through conformal prediction and using them to generate scenarios.\nThis work was financially supported by the Swiss Federal Office of Energy (ODIS \u2013 Optimal DSO dISpatchability, SI/502074), partly by the Swiss National\nScience Foundation under NCCR Automation (grant agreement 51NF40 180545), and supported by IEA Annex 82 \u201dEnergy Flexible Buildings Towards Resilient Low Carbon Energy Systems\u201d.

The first decision is taken by the building central controller, which decides its working mode, that is, if the building needs to be cooled or heated, based on a moving average of the historical data of the external temperature:\nwhere the working mode  is negative when the building requires to be cooled, positive when heating is required, and 0 when no actions are needed. and  represent the maximum and minimum values of the external temperature\u2019s moving average, which is based on the past 7 days.\nThe actual activation of the heating element is controlled by the hysteresis on the internal temperature of the building, . If the working mode is positive, this is given by:\nwhere  is the state of the hysteresis at time , 1 meaning that the circulation pump of the heating element must be activated, and  was chosen to be equal to 1. For completeness, we report also the control logic when the building is in cooling mode:\nThe incoming water temperature in the heating element is then modulated linearly through a 3-way valve between a maximum and minimum value, based on the external temperature, both in the heating and cooling modes.\nWhen operative, the heating element requests hot or cold water to the water tank, which control logic is based on two temperature sensors located in two different layers. When the building is in heating mode, the control logic is a simple hysteresis based on the temperature of the sensor in the uppermost layer, which is identical to the one in (12  ###reference_###). When in cooling mode, the control logic is the following:\nwhere  and  are the temperature measured by the upper and lower sensors, respectively, and  and  are the minimum and maximum desired temperatures of the water in the tank while in cooling mode. \nThe value of  is then communicated to the HP. In the case in which the HP is also used for the domestic hot water (DHW), the DHW tank is always served with priority by the HP.\nFloor heating was modeled starting from the first principles. Considering a fixed and uniform temperature for the ground and the building internal temperature at each time-step and stationary conditions, we can retrieve the analytical expression of the temperature profile along the pipe, through the energy balance on an infinitesimal element of the pipe. This can be expressed as:\nwhere  is the heat capacity in ,  is the distance from the pipe entrance,  is the temperature of the water inside the pipe at ,  are enthalpy flows at the entrance and exit of the considered infinitesimal volume,  and  are the heating powers from the building and from the ground.\nExpressing the latter through equivalent resistance taking into account convective and conductive effects, the balance in steady state can be rewritten as:\nwhere  is the asymptotic temperature and where:\nwhere  is the diameter of the tube,  is the internal coefficient of heat transfer, which can be retrieved using available empirical relation for fully developed flow with fixed temperature at the boundary conditions [35  ###reference_b35###],  is the heat transfer coefficient between the floor and the building air including both the effect for natural convection and radiation. The values of  can be found in the literature [36  ###reference_b36###]. The value of the thermal resistances  and , towards the floor and the ground, can be found in the literature as well. We can reformulate (16  ###reference_###), making it adimensional through a change of variable:\nfrom which solution we can retrieve the temperature profile of the water inside the pipe:\nwhere  is the temperature of the water at the pipe inlet. We can use (21  ###reference_###) to retrieve the heating power flowing into the building, integrating  along the pipe.\nwhere  is the length of the serpentine. Integrating, we obtain\nwhere  is the temperature of the water at the outlet of the serpentine. Note that the equation (23  ###reference_###) tends to  when  increase and  is kept fixed.\nThe nominal mass flow of the heating system and the length of the serpentine are found as the solution of the following optimization problem:\nwhere  is a reference mass flow, equal to  and  is the power required to keep the building internal temperature constant under reference conditions (we used an external temperature of -4 and a desired internal temperature of 20 ):\nwhere  is the resistance of an equivalent RC circuit describing the heating dynamics of the building.\nThe dynamic equation describing the evolution of the temperature of the tank\u2019s layers is the following:\nwhere  is the temperature of the  layer, ,,, are the thermal powers due to buoyancy and conduction, from the lower and upper layer, respectively. The last term represents the enthalpy flow due to mass exchange, while  is the thermal capacity of the layer, in  and  is the thermal power due to an electric resistance (for the boiler) or an heat exchange (for the heating system buffer).\nThe expression for the above thermal power are the following:\nwhere  is the number of layers,  is the equivalent thermal loss coefficient with the ambient and  is the set of the  layers heated by the heat exchange (or electric resistance). The buoyancy model is the one proposed in the\nIDEAS library [21  ###reference_b21###].\nA detailed description of the parameters for the boiler model can be found in [37  ###reference_b37###]."

This paper investigates LoRA composability for cross-task generalization and introduces LoraHub, a simple framework devised for the purposive assembly of LoRA modules trained on diverse given tasks, with the objective of achieving adaptable performance on unseen tasks.\nWith just a few examples from a new task, LoraHub can fluidly combine multiple LoRA modules, eliminating the need for human expertise and assumptions.\nNotably, the composition requires neither additional model parameters nor gradients.\nEmpirical results on the Big-Bench Hard benchmark suggest that LoraHub, while not surpassing the performance of in-context learning, offers a notable performance-efficiency trade-off in few-shot scenarios by employing a significantly reduced number of tokens per example during inference.\nNotably, LoraHub establishes a better upper bound compared to in-context learning when paired with different demonstration examples, demonstrating its potential for future development.\nOur vision is to establish a platform for LoRA modules, empowering users to share their trained LoRA modules. This collaborative approach facilitates the seamless application of LoRA modules to novel tasks, contributing to an adaptive ecosystem.\nOur code is available at github.com/sail-sg/lorahub, and all the pre-trained LoRA modules are released at huggingface.co/lorahub.",

+            "text": "###figure_1### Recent progress in natural language processing (NLP) has been largely fueled by large language models (LLMs) such as OpenAI GPT (Brown et al., 2020  ###reference_b5###), FLAN-T5 (Chung et al., 2022  ###reference_b8###), and LLaMA (Touvron et al., 2023  ###reference_b47###). These models demonstrate top-tier performance across different NLP tasks. However, their enormous parameter size presents issues regarding computational efficiency and memory usage during fine-tuning. To mitigate these challenges, Low-Rank Adaptation (LoRA) (Hu et al., 2022  ###reference_b15###) has emerged as a parameter-efficient fine-tuning technique (Lester et al., 2021  ###reference_b23###; He et al., 2022  ###reference_b14###; An et al., 2022  ###reference_b2###). By reducing memory demands and computational costs, it speeds up LLM training. LoRA achieves this by freezing the base model parameters (that is, an LLM) and training a lightweight module, which regularly delivers high performance on target tasks.\nWhile prior research has targeted the efficiency enhancement facilitated by LoRA, there is a dearth of investigation into the inherent modularity and composability of LoRA modules. Typically, previous methods train LoRA modules to specialize in individual tasks. Yet, the intrinsic modularity of LoRA modules presents an intriguing research question: Would it be possible to compose LoRA modules to generalize to novel tasks in an efficient manner?\nIn this paper, we tap into the potential of LoRA modularity for broad task generalization, going beyond single-task training to meticulously compose LoRA modules for malleable performance on unknown tasks. Crucially, our method enables an automatic assembling of LoRA modules, eliminating dependency on manual design or human expertise. With just a handful of examples from new tasks (e.g., 5), our approach can autonomously compose compatible LoRA modules without human intrusion.\nWe do not make assumptions about which LoRA modules trained on particular tasks can be combined, allowing for flexibility in amalgamating any modules as long as they conform to the specification (e.g., using the same LLM).\nAs our approach leverages several available LoRA modules, we refer to it as LoraHub and denote our learning method as LoraHub learning.\nTo validate the efficiency of our proposed methods, we test our approaches using the widely recognized BBH benchmark with FLAN-T5 (Chung et al., 2022  ###reference_b8###) serving as the base LLM. The results underline the effectiveness of the LoRA module composition for unfamiliar tasks through a few-shot LoraHub learning process.\nNotably, our methodology achieves an average performance that closely matches that of few-shot in-context learning, while demonstrating a superior upper bound, particularly when using different demonstration examples.\nAdditionally, our method substantially reduces the inference cost compared to in-context learning, eliminating the requirement of examples as inputs for the LLM.\nWith fewer tokens per example during inference, our method significantly reduces computational overhead and enables faster responses.\nIt aligns with a broader research trend, where recent studies are actively exploring approaches to reduce the number of input tokens (Zhou et al., 2023  ###reference_b59###; Ge et al., 2023  ###reference_b11###; Chevalier et al., 2023  ###reference_b6###; Jiang et al., 2023a  ###reference_b19###; Li et al., 2023  ###reference_b24###; Jiang et al., 2023b  ###reference_b20###).\nOur learning procedure is also notable for its computational efficiency, using a gradient-free approach to obtain the coefficients of LoRA modules and requiring only a handful of inference steps for unseen tasks.\nFor example, when applied to a new task in BBH, our methodology can deliver superior performance in less than a minute using a single A100 card.\nImportantly, LoraHub learning can feasibly be accomplished with a CPU-only machine, requiring proficiency solely for processing LLM inference. In our pursuit to democratize artificial intelligence, we are taking an important step forward by envisioning the establishment of the LoRA platform. The platform would serve as a marketplace where users can seamlessly share and access well-trained LoRA modules for diverse applications.\nLoRA providers have the flexibility to freely share or sell their modules on the platform without compromising data privacy.\nUsers, equipped with CPU capability, can leverage trained LoRA modules contributed by others through automated distribution and composition algorithms.\nThis platform not only cultivates a repository of reusable LoRA modules with a myriad of capabilities but also sets the stage for cooperative AI development.\nIt empowers the community to collectively enrich the LLM\u2019s capabilities through dynamic LoRA composition."

Constructing these hypernetworks demands for substantial GPU memory and time, posing a challenge. Given that  consists of a relatively small number of parameters, we opted for gradient-free methods for optimization instead of gradient descent.\nInspired by previous work (Sun et al., 2022  ###reference_b45###), we utilize a black-box optimization technique to find the optimal . The optimization process is steered by the cross-entropy loss, setting the goal to locate the best set  that reduces the loss  on the few-shot examples . Furthermore, we incorporate L1 regularization to penalize the sum of the absolute values of , helping to prevent obtaining extreme values. Consequently, the final objective of LoraHub is to minimize , where  serves as a hyperparameter.\nIn terms of the gradient-free method, we leverage Shiwa, a combinatorial optimization approach (Liu et al., 2020  ###reference_b27###). Shiwa offers a variety of algorithms and chooses the most suitable optimization algorithm for different circumstances. In most of the forthcoming experimental setups, we primarily employ the Covariance Matrix Adaptive Evolution Strategies (CMA-ES) (Hansen & Ostermeier, 1996  ###reference_b13###). CMA-ES, as a stochastic and population-based optimization algorithm, offers versatility in addressing a broad spectrum of optimization challenges.\nIt dynamically adjusts a search distribution, which is defined by a covariance matrix. During each iteration, CMA-ES systematically updates both the mean and covariance of this distribution to optimize the target function. In our application, we employ this algorithm to mold the search space for . Ultimately, we use it to identify the optimal  by evaluating their performance on the few-shot examples from an unseen task."

For parity with FLAN, we adopt the tasks utilized to instruct FLAN-T5, thereby incorporating nearly  distinct tasks and their corresponding instructions. Following this, we trained several LoRA modules as potential candidates.\nDuring each experimental sequence, we randomly select  LoRA modules from them as the candidate for our LoraHub learning.\nOur method is evaluated using the Big-Bench Hard (BBH) benchmark, a well-established standard that consists of multiple-choice questions from a variety of domains.\nThe benchmark consists of  different tasks, which are regarded to be challenging for language models.\nFor all tasks, we employ the exact match (EM) as our evaluation metric.\n###table_1### To enhance the demonstration of our method\u2019s performance, we expanded our comparisons beyond the zero-shot and in-context learning settings. We specifically chose three representative gradient-based methods for comparison: full fine-tuning (FFT), LoRA tuning (LoRA) (Hu et al., 2022  ###reference_b15###), and IA3 fine-tuning (IA3) (Liu et al., 2022  ###reference_b26###).\nFor all gradient-based methods, for a fair comparsion, we train for  epochs on the same three runs of  examples employed in our methods.\nIn the case of FFT, a learning rate of 3e-5 is employed, whereas for IA3 and LoRA, we adopt a learning rate of 2e-4.\nWe report the performance of each method on the test set at the end of training (averaged over three runs) without any model selection to avoid potential selection bias."

For example, as depicted in Table 1  ###reference_###, our method exhibits a notable improvement of  on average in contrast to the promising IA3 method. Nevertheless, we acknowledge that our approach still falls behind LoRA tuning and full fine-tuning, especially in tasks that exhibit significant deviation from the upstream task.

However, it introduces an inherent cost during the Adapt stage, necessitating extra inference steps, such as the  steps employed in our experiments. This introduces a trade-off between choosing the ICL approach and LoraHub, with the decision typically hinging on the nature of the situation.\nFor one-time ad-hoc tasks, the ICL approach should be more pragmatic due to LoraHub\u2019s additional inference step costs. In such scenarios, where immediate, single-use solutions are preferred, the simplicity and efficiency of ICL might outweigh the benefits of potential savings offered by LoraHub. Conversely, for recurring or similar tasks, LoraHub emerges as a compelling option. Despite the added inference step cost, LoraHub\u2019s ability to efficiently handle repetitive tasks, often occurring thousands of times, while concurrently reducing overall expenses, positions it as a viable option in such kind of situations.\nIn summary, our intention is not to replace ICL, but to present LoraHub as a complementary strategy with performance-efficiency trade-offs. Thus, we encourage a careful consideration of specific use cases and requirements when choosing between ICL and LoraHub, recognizing that the optimal solution may vary based on the nature and frequency of the tasks at hand."

If not specified, we use FLAN-T5-large for all analysis.\nDoes composing LoRA modules extend beyond the single module\u2019s benefits?\n###table_2### We acknowledge the investigation of cross-task performance in prior work (Jang et al., 2023  ###reference_b18###), which delved into the capabilities of LoRA and proposed a novel method centered around LoRA module retrieval.\nIn order to ensure a fair comparison, we conducted an experiment where we designed a LoRA retrieval mechanism based on the loss derived from few-shot examples.\nSpecifically, we ranked all LoRA module candidates according to this loss and evaluated the best candidate on the test set of the unseen task.\nAs depicted in Table 2  ###reference_###, the performance of LoRA retrieval is notably impressive, positioning it as a strong baseline. However, in comparison to LoraHub, the performance of LoRA retrieval is relatively less favorable\nHow effective is the gradient-free optimization method?\nTo assess the effectiveness of our gradient-free optimization method in correctly identifying the most suitable LoRA module for a given downstream task, we carried out an empirical study using the WikiTableQuestions (Pasupat & Liang, 2015  ###reference_b37###) (WTQ) dataset.\nWe strategically included a LoRA module that was specifically trained on the WTQ dataset into our pool of LoRA candidate modules, which originally stemmed from tasks exclusive to the Flan Collection. Subsequently, we designated WTQ as the targeted downstream task and computed the weights consistent with the methods employed in LoraHub learning. As an end result, the WTQ-specific LoRA module was awarded the highest weight, exemplifying the algorithm\u2019s success in recognizing it as the most relevant.\nMoreover, the combined LoRA module demonstrated marginal superiority over the WTQ LoRA module.\nThis underscores the claim that the gradient-free optimization method has the ability to proficiently select the optimal upstream LoRA module for an unseen task.\nCan LoraHub work well on non-instruction-tuning models?\nIn previous investigations, we primarily focused on models with zero-shot capabilities that were trained with instruction tuning. However, for models like T5 without zero-shot abilities, where training has a larger effect on parameters, it was unclear if LoraHub could still effectively manage and improve them. Our experiments show that although these models perform worse than FLAN-T5, LoraHub learning can still enable them to effectively generlize to unseen tasks. See Appendix C  ###reference_### for more details.\nWill the rank of LoRA modules impact the performance of LoraHub learning?\nThe parameter rank plays a crucial role in the LoRA framework, directly influencing the number of trainable parameters utilized during LoRA tuning. This prompts an intriguing question: does the variation in rank values influence the outcomes observed within the LoraHub learning? Our analysis indicates that, for FLAN-T5, the choice of rank has minimal impact. However, for T5, it still exerts some influence. Empirical findings reveal that, in comparison to rank values of  or , a rank value of  consistently demonstrates superior performance across different runs, both in terms of average and optimal values. Additional results are available in Appendix C  ###reference_###.\nDoes more LoRA modules lead to better results?\nIn our main experiments, we randomly selected  LoRA modules for LoraHub learning. Therefore, we conducted experiments to investigate the effect of using different numbers of LoRA modules. The results demonstrate that as we increased the number of LoRA modules, the variance in performance increased. However, the maximum achievable performance also improved. More analysis on the variance and the detailed results can be found in Appendix H  ###reference_###.\nHow much computational resource can be saved?\n\nWe follow to the memory test settings from the LoRA-FA (Zhang et al., 2023b  ###reference_b58###) study for an accurate benchmark. In this context, full fine-tuning required about 40GB of memory, whereas LoRA fine-tuning used around 34GB. Remarkably, LoraHub only utilized about 5GB of memory, illustrating its efficiency due to the inference-only mode, which eliminates the need for storing gradients and optimization states."

Our approach enables the fluid combination of multiple LoRA modules using just a few examples from a novel task, without requiring additional model parameters or human expertise. The empirical results on the BBH benchmark demonstrate that LoraHub can effectively match the performance of in-context learning in few-shot scenarios, removing the need for in-context examples during inference.\nOverall, our work shows the promise of strategic LoRA composability for rapidly adapting LLMs to diverse tasks.\nBy fostering reuse and combination of LoRA modules, we can work towards more general and adaptable LLMs while minimizing training costs."

To evaluate this, we examined the extent of influence a single LoRA module had amongst all tasks from the BBH benchmark. We measured the impact of each isolated task by calculating the average absolute weight. The top five modules, presented in Table 3  ###reference_###, were found to have substantial influence, as indicated by their maximum average weights, which suggested that they were notably more effective in cross-task transfer.\nRemarkably, a common feature among these top five modules was their association with tasks requiring reading comprehension and reasoning skills\u2014attributes indicative of higher cognitive complexity.\nHowever, it is worth noting that none of the modules exhibited consistent improvement across all BBH tasks, as reflected in their average performance on all BBH tasks, which did not show a significant improvement compared to the original FLAN-T5-large, except for the Rank 2.\nThe results underscore the advantages of composing diverse modules in LoraHub.\n###table_3### How effective is the gradient-free optimization method?\nTo assess the effectiveness of our gradient-free optimization method in correctly identifying the most suitable LoRA module for a given downstream task, we carried out an empirical study using the WikiTableQuestions (Pasupat & Liang, 2015  ###reference_b37###) (WTQ) dataset.\nWe strategically included a LoRA module that was specifically trained on the WTQ dataset into our pool of LoRA candidate modules, which originally stemmed from tasks exclusive to the Flan Collection.

+            "text": "Recent advancements in natural language processing have been predominantly driven by the development of large language models (LLMs) (Brown et al., 2020  ###reference_b2###; OpenAI, 2022  ###reference_b29###; 2023  ###reference_b30###; Chowdhery et al., 2023  ###reference_b6###; Smith et al., 2022  ###reference_b40###).\nThese models have demonstrated remarkable performance across a wide range of tasks (Qin et al., 2023  ###reference_b33###; Bubeck et al., 2023  ###reference_b3###; Huang & Chang, 2023  ###reference_b12###).\nOne of the key features that enables these models to excel is their ability to perform in-context learning (Dong et al., 2022  ###reference_b9###). By conditioning on given context, LLMs can adapt to new tasks and domains without the need for task-specific fine-tuning. This enables LLMs to perform well on zero-shot or few-shot learning tasks, where only a limited number of examples are available.\nWhile in-context learning has been extensively studied for decoder-only language models like GPT-3 (Brown et al., 2020  ###reference_b2###) and PaLM (Chowdhery et al., 2023  ###reference_b6###), research on encoder-decoder language models, which have shown to learn stronger representations (Devlin et al., 2019  ###reference_b8###; Raffel et al., 2020  ###reference_b35###), remains limited. Notably, Patel et al. (2023  ###reference_b31###) tap into the potential of mT5 (Xue et al., 2021  ###reference_b46###), a multilingual encoder-decoder LM, by iteratively prompting the model to produce long generations with in-context examples. Chung et al. (2022  ###reference_b7###); Longpre et al. (2023  ###reference_b24###) finetune T5 (Raffel et al., 2020  ###reference_b35###) with a large mixture of tasks using instruction tuning (Mishra et al., 2022  ###reference_b28###; Wei et al., 2022  ###reference_b45###; Sanh et al., 2022  ###reference_b37###) to improve model performance and generalization to unseen tasks in both zero-shot and few-shot settings.\nOn the other hand, LLMs still face challenges such as hallucination and limitations in representing the long-tail and most recent knowledge (Mallen et al., 2022  ###reference_b27###; Huang et al., 2022  ###reference_b13###; Luu et al., 2022  ###reference_b26###; Jang et al., 2022  ###reference_b17###; Zheng et al., 2023  ###reference_b48###). Retrieval-augmented language models (Izacard et al., 2023  ###reference_b16###; Borgeaud et al., 2022  ###reference_b1###; Wang et al., 2023  ###reference_b44###; Shi et al., 2023  ###reference_b39###) have emerged as a powerful approach to address these issues by retrieving relevant knowledge from an external corpus.\nAmong these, the encoder-decoder models, such as Atlas (Izacard et al., 2023  ###reference_b16###), stand out. They benefit from the strong representation ability of a bidirectional encoder, coupled with of the efficacy of a Fusion-in-Decoder architecture (Izacard & Grave, 2021  ###reference_b14###), enabling the effective integration of multiple retrieved passages.\nDespite these advancements, in-context learning with these models remains underexplored.\nIn this regard, we first conduct a comprehensive analysis of the state-of-the-art retrieval-augmented encoder-decoder language models by designing and experimenting with different prompting strategies. We find that these models exhibit a certain in-context learning ability; however, due to a mismatch between pretraining and inference and a limited context length\u2014issues that are common to existing encoder-decoder LMs trained with masked language modeling\u2014its few-shot performance is not stable\nand providing more than, e.g., 8-shot, examples does not lead to further improvement.\nBased on the analysis, we develop Raven111Raven, a bird known for its intelligence and adaptability, has the letters \u201cRA\u201d in its name, which represents \u201cRetrieval-Augmented\u201d in our context. by first mitigating the mismatch between pretraining and inference through a combination of retrieval-augmented masked language modeling and prefix language modeling. Moreover, to enable the model to learn from more in-context examples, we propose Fusion-in-Context Learning, a novel approach that allows the model to utilize more in-context examples without modifying the model configuration or requiring additional training. Furthermore, we suggest using the retriever of the model to obtain relevant in-context examples to further enhance few-shot performance. Our empirical results demonstrate that Raven significantly outperforms previous retrieval-augmented encoder-decoder LMs in both zero-shot and few-shot settings, even achieving comparable results to decoder-only LLMs in some settings despite having 180 times fewer parameters.\nThe main contributions of this paper are twofold:\nFrom an analytical standpoint, we provide a thorough analysis of the in-context learning ability of retrieval-augmented encoder-decoder language models. We demonstrate the possibilities and offer insights for future development.\nFrom a technological perspective, we introduce Raven, coupled with our Fusion-in-Context Learning and In-Context Example Retrieval strategies, building upon the analytical groundwork. These techniques, though simple, are highly effective. They not only enhance the base model\u2019s capabilities but also highlight the potential of in-context learning with retrieval-augmented encoder-decoder LMs."

These models typically employ an information retrieval mechanism to access relevant information from a large corpus, which is then integrated into the model\u2019s prediction process.\nRetrieval-augmented LMs can be based on both encoder-decoder (Izacard et al., 2023  ###reference_b16###; Lewis et al., 2020  ###reference_b22###) and decoder-only (Khandelwal et al., 2020  ###reference_b19###; Borgeaud et al., 2022  ###reference_b1###; Shi et al., 2022  ###reference_b38###) architectures.\nFor decoder-only LMs, the computational cost typically increases quadratically with the input length, as well as with the number of retrieval passages. In contrast, for encoder-decoder LMs with a Fusion-in-Decoder architecture, the computation cost grows linearly with the number of retrieved passages, as they only perform self-attention over one passage at a time (Izacard & Grave, 2021  ###reference_b14###). This concept is also investigated by Ye et al. (2023  ###reference_b47###) for more efficient in-context learning.\nWhile there has been some research on in-context learning with retrieval-augmented decoder-only LMs, which can be straightforwardly implemented by concatenating retrieved passages with the query as the input of the LM (Mallen et al., 2022  ###reference_b27###; Shi et al., 2023  ###reference_b39###; Khattab et al., 2022  ###reference_b20###), in-context learning with retrieval-augmented encoder-decoder LMs remains unexplored to the best of our knowledge. This is despite the fact that encoder-decoder LMs can be more efficient at\nincorporating multiple (e.g., 40) retrieved passages."

+            "text": "###figure_1### To investigate the in-context learning ability of retrieval-augmented encoder-decoder language models, we first aim to gain insights from the state-of-the-art designs in the literature. Among them, the design of Atlas (Izacard et al., 2023  ###reference_b16###) stands out; it combines a general-purpose dense retriever with a sequence-to-sequence reader (i.e., T5 (Raffel et al., 2020  ###reference_b35###)) using the Fusion-in-Decoder architecture (Izacard & Grave, 2021  ###reference_b14###). The retriever, encoder and decoder are jointly trained during the pretraining process. In this process, the dense retriever, based on the Contriever model (Izacard et al., 2022  ###reference_b15###), is responsible for selecting relevant passages from an external knowledge source, e.g., Wikipedia, based on the given corrupted context. The retrieved passages are then processed along with the context by the encoder, which generates the corresponding output, i.e., the masked spans, at the decoder (Figure 1  ###reference_###, left).\nAtlas demonstrates exceptional few-shot performance on knowledge-intensive language tasks (Petroni et al., 2021  ###reference_b32###), despite having a lower parameter count compared to other recent LLMs.\nHowever, in Izacard et al. (2023  ###reference_b16###), the few-shot performance is achieved by finetuning the model with few-shot examples, which requires additional training and may limit its applications, such as dealing with dynamic and diverse real-time user queries like GPT-3/4 (Brown et al., 2020  ###reference_b2###; OpenAI, 2023  ###reference_b30###), where in-context learning plays a vital role.\nTherefore, we take the initiative to explore the in-context learning ability of this type of models, using open-domain question answering (Chen et al., 2017  ###reference_b4###) as a representative task for some preliminary experiments.\nPrompting Strategies.\nTo facilitate in-context learning, an effective prompting strategy is paramount.\nIn contrast to decoder-only LMs, where the input can only be fed to the decoder, encoder-decoder LMs can take input in either the encoder or the decoder. In alignment with the pretraining objective, we identify two prompting strategies for in-context learning:\nStrategy 1. The first strategy involves feeding all example question-answer pairs and the target question to the encoder, without any input to the decoder. The prompt is designed as:222Here we present a format designed for better demonstration. The actual prompt, which follows the template used in pretraining, can be found in Appendix B.4  ###reference_###.\nEnc: Question:  Answer:   Question:  Answer:  Question:  Answer:<extra_id_0>\nwhere  represent example QA pairs,  denotes the target question, <extra_id_0> is a sentinel\ntoken (Raffel et al., 2020  ###reference_b35###), and  is the relevant passage retrieved with . An example in a 2-shot setting is illusated in\nFigure 1  ###reference_### (middle).\nStrategy 2. As the decoder of the encoder-decoder model can also accept input, we can feed the answers of in-context examples to the decoder and only feed the questions to the encoder, using multiple sentinel tokens:\nEnc: Question:  Answer:<extra_id_0>  Question:  Answer:<extra_id_> Question:  Answer:<extra_id_>\nDec: <extra_id_0>  <extra_id_>\nFigure 1  ###reference_### (right) demonstrates an example. The model is expected to learn from in-context examples by examining both the input to the encoder and input to the decoder.\nWe select two widely-used datasets in the domain of open-domain question answering for the preliminary study: Natural Questions (NQ) (Kwiatkowski et al., 2019  ###reference_b21###) and TriviaQA (TQA) (Joshi et al., 2017  ###reference_b18###)333Experimental setup is detailed in the Appendix B.1  ###reference_###.. Table 1  ###reference_### summarizes the results. We find that the model struggles to learn from in-context examples using strategy 2, as the few-shot performance is worse than the zero-shot performance.\nWe hypothesize that this is because the model has difficulty learning the pattern of S2 with masked language modeling during its pretraining, since it is unlikely to obtain several consecutive question-answer pairs (or something similar) in the form of strategy 2 by randomly masking several spans in a sequence.\nOn the other hand, we observe that with strategy 1, the model does exhibit some in-context learning ability, where the 5-shot and 8-shot performance is significantly better than the zero-shot performance on both NQ and TriviaQA. Therefore, we choose to focus on strategy 1 for further study and disregard strategy 2 for the remainder of the paper.\n\n###figure_2### Effect of Position.\nAs the encoder of encoder-decoder language models is bidirectional, it can also examine in-context examples that follow the target question to fill in the masked token. This means that we may position the target question at the beginning or middle of a sequence, for example:\nQuestion:  Answer:<extra_id_0> Question:  Answer:   Question:  Answer:\nQuestion:  Answer:   Question:  Answer:<extra_id_0> Question:  Answer:\nTable 2  ###reference_### summarizes the results. We denote the target question\u2019s position as \u201cfirst\u201d for the beginning of the sequence, \u201crandom\u201d for a random position, and \u201clast\u201d for the original setting (S1). Interestingly, placing the target question anywhere other than the last position results in a significant performance drop.\nUpon examining the generated answers, we observe that when the target question is placed at the beginning or in the middle, the model tends to repeat the answer or generate additional text. For example, for the prompt \u201cQuestion: What number in Bingo is sometimes referred to as Heinz varieties? Answer:<extra_id_0> Question: \u2026\u201d. The generated text is \u201c57 \u2018Heinz varieties\u2019 is a term used in Bingo to describe\u201d. This indicates that the model does not fully understand and follow the style of in-context examples.\nTherefore, by default, we position the target question after all the in-context examples.\nEffect of Number of In-Context Examples.\n\nThe number of in-context examples is a crucial hyperparameter for in-context learning. Generally, we expect better performance from a model with more in-context examples, but there is an upper limit due to 1) the maximum context length setup, e.g., 512 tokens, during the pretraining process, and 2) the point at which the model has received sufficient examples and cannot gain additional information from more examples.\nThe optimal number of in-context examples also varies between models. For instance, on TriviaQA, PaLM (Chowdhery et al., 2023  ###reference_b6###) exhibits better 1-shot performance than settings with more examples, while this is not the case for GPT-3 (Brown et al., 2020  ###reference_b2###).\nFigure 2  ###reference_### illustrates the impact of varying the number of in-context examples across different model sizes. Interestingly, the 11B model demonstrates poor performance in low-shot settings, e.g., 1-shot, but improves significantly after 4-shot and 5-shot. Upon examining the generated responses, we find that the model tends to produce answers with more tokens in low-shot settings, while the ground truth typically consists of shorter answers with fewer than 5 tokens.\nBy relaxing the criteria for a correct prediction to include instances where the ground-truth answer is a substring of the model output, we find that the 1-shot performance surpasses that of the 0-shot setting (38.3 vs 32.1 on NQ).\nAll models perform well in the 5-shot and 8-shot settings, but their performance does not continue to improve with more in-context examples (e.g., 16-shot). We believe this plateau may be attributed to two factors: 1) the sequence length constraints during pretraining, where the maximum input length to the encoder is set to 384 tokens, and the average input sequence length (excluding passages) is around 130 tokens; 2) the model\u2019s ability to learn adequately with 5 or 8 examples, making additional examples less beneficial.\n\n###figure_3### Effect of Number of Retrieved Passages.\nFigure 3  ###reference_### illustrates the impact of the number of retrieved passages on model performance. We observe that for both 0-shot and 5-shot settings, the performance of the models increases significantly with the number of retrieved passages. This highlights the effectiveness of the Fusion-in-Decoder architecture (Izacard & Grave, 2021  ###reference_b14###) for knowledge-intensive tasks like open-domain question answering, and underscores the importance of pretraining language models with retrieval augmentation.\nAdditionally, the 5-shot performance consistently outperforms the 0-shot setting.\nThis observation further emphasizes the value of providing in-context examples to improve the performance of retrieval-augmented encoder-decoder language models."

(2023  ###reference_b16###), a practical choice is to pretrain the model with the masked language modeling objective, where the input is a corrupted text with several masked spans placed randomly within the sequence (refer to Figure 1  ###reference_### (left) for an example).\nHowever, in testing, based on our analysis in \u00a73.1  ###reference_###, it is most effective to place the target question after all the in-context examples, with a masked token (i.e., <extra_id_0>) following the question (Figure 1  ###reference_###, middle)).\nThus, there exists a mismatch between pretraining and inference.\nTo solve this issue, we propose combining retrieval-augmented masked and prefix language modeling. Specifically, in the first stage, following Izacard et al. (2023  ###reference_b16###), the retriever and reader are trained jointly with retrieval-augmented masked language modeling. The training objective for the retriever is to minimize the KL divergence  between the passage posterior distribution according to the reader and the passage distribution from the retriever over the top-K retrieved passages, i.e.,\n\nwhere  calculates the dot product between the query  and passage  vectors, and  is a hyperparameter. The training objective for the reader is to maximize the likelihood of the masked spans with  retrieved passages: .\nIn the second stage, for each sequence, we mask 10% of the tokens on average at the end of the sequence with the <extra_id_0> token. Then, we use the retriever obtained from the first stage to retrieve relevant passages using the prefix and train the reader to recover the suffix of this sequence with the prefix and the passages as input. An example of input and output for retrieval-augmented prefix language modeling is shown in Figure 4  ###reference_###. We can observe that the pretraining objective aligns more closely with prompting strategy 1 in Figure 1  ###reference_###. We refer to the model trained with this combined objective as Raven.\nRaven benefits from both the retrieval-augmented masked language modeling, which contributes to a better reader and retriever, and retrieval-augmented prefix language modeling, which mitigates the gap between pretraining and inference. This design is non-trivial. In Appendix C.1  ###reference_###,\nwe verify the effectiveness of it by exploring different training strategies."

One major reason for this is the limited sequence length during the pretraining process, which makes it difficult for the model to handle long sequences during inference. Pretraining models with longer contexts would be a potential solution, but it would significantly increase computation cost. Additionally, the maximum input length is also constrained by the maximum sequence length of the retriever, i.e., Contriever, which is based on BERT (Devlin et al., 2019  ###reference_b8###) and has a maximum length of 512 tokens.\nAs an alternative, we propose an approach to enable models to learn from more in-context examples without requiring additional training. As described in \u00a73.1  ###reference_###, the reader is based on the Fusion-in-Decoder architecture (Izacard & Grave, 2021  ###reference_b14###), where multiple passages are retrieved, and each passage, concatenated with the in-context examples and target question, is fed to the encoder separately (Figure 5  ###reference_###, top).\nTo allow the model to process more in-context examples, we can feed different in-context examples to the encoder with each passage (Figure 5  ###reference_###, bottom). In this way, the model can incorporate more in-context examples during its inference process. We refer to this strategy as Fusion-in-Context Learning (FiCL).\n\n###figure_5### In implementation, for a -shot setting, such as a 64-shot setting, to effectively utilize the 64 examples, we randomly shuffle these examples and select  (e.g., 5) examples in order as the input for the encoder each time.\nIf all the examples have been used, we shuffle the 64 examples again. We denote the configuration of FiCL as [-], which stands for [-shot, -fusion]."

Without this, users would need to manually provide in-context examples; and 2) optimize the selection of in-context examples, thereby improving in-context learning performance."

Both the 3B and 11B Raven models significantly outperform Atlas.\nFor instance, on TriviaQA, Raven 11B achieves an improvement of 8.8%, 30.7%, and 2.8% in the 0-shot, 1-shot, and few-shot settings respectively, compared to Atlas 11B.\nFurthermore, the performance of Raven increases steadily with the number of in-context examples, while the performance of Atlas experiences a substantial decline in low-shot settings, demonstrating the effectiveness of Raven across various shot settings.\nFusion-in-Context Learning. We also report the results of models with Fusion-in-Context Learning (FiCL) in Table 3  ###reference_###. For both Atlas and Raven, FiCL contributes to approximately a 1% improvement, which is not attainable by standard in-context learning, where performance does not further improve (or even decreases) with more than  in-context examples. This demonstrates the superiority of FiCL for enabling models to learn from more examples.\n\n###figure_7### Comparison to Other Models. In Table 3  ###reference_###, we further compare Raven to other baselines.\nOn NQ, Raven\u2019s zero-shot and one-shot performance surpasses all the baselines, including PaLM, even though Raven 3B has 180 times fewer parameters than PaLM 540B. The zero-shot performance of Raven on TriviaQA is also on par with PaLM 62B.\nFurthermore, Raven\u2019s zero-shot performance significantly exceeds that of both Retro and Retro++, which are retrieval-augmented language models of a similar scale.\nIn the few-shot setting, with FiCL, Raven achieves performance comparable to GPT-3 175B and PaLM 62B. However, there remains a gap between Raven and the larger PaLM 540B and Codex 175B models. Nevertheless, given the considerably smaller scale of Raven in comparison to PaLM and Codex, its performance can be considered impressive. The performance of Raven may be further improved if it is built upon a larger model, in which case its few-shot performance is likely to surpass that of PaLM and Codex.\nEffect of Number of Retrieved Passages.\nFigure 7  ###reference_### illustrates the effect of the number of retrieved passages.

We expect further improvement of Raven by applying instruction tuning as well and leave it for future study.\nInterestingly, with standard in-context learning, the few-shot performance of Raven is worse than zero-shot, possibly due to the longer questions and answer options in MMLU causing context length issues in the 5-shot setting.\nAlso, in the one-shot setting, since MMLU is a multiple-choice QA task, providing only one example might introduce bias in the model\u2019s prediction, favoring a specific option.

One limitation arises from the constrained context length inherent to the base models (i.e., T5 or Atlas) we employed. This restriction poses challenges to the scalability of in-context learning, especially as the number of in-context examples increases. While our Fusion-in-Context Learning (FiCL) strategy does offer a mitigative approach to this constraint, an alternative and possibly more optimal solution might involve extending the context length. This would be particularly beneficial for tasks requiring extensive inputs.\nFurthermore, when compared to some of the prevailing decoder-only language models, particularly those exceeding 100B parameters, the models deployed in our research might appear relatively diminutive in scale (in terms of both the number of parameters and the amount of training data).\nOur endeavor partially seeks to catalyze further investigations into more powerful encoder-decoder models.\nNonetheless, the insights and methods proposed are transferable and have the potential to enhance other models, including those that are domain-specialized or more powerful, such as mT5 (Xue et al., 2021  ###reference_b46###) and UL2 (Tay et al., 2023  ###reference_b42###).\nFuture work focusing on scaling up the model, applying these methods, and further studying its in-context learning ability is encouraged.\nDrawing on the benefits of scaling up and combining this with our proposed approaches, we believe that there is potential to develop even more powerful retrieval-augmented language models in the future.\nAnother promising future direction is exploring how to combine the Fusion-in-Decoder architecture with existing decoder-only language models. By doing so, we can harness the advantages of both architectures\u2014employing a bidirectional architecture to effectively encode retrieved passages for the most powerful decoder-only LLMs."

To isolate the effect of training variance with masked language modeling, we initialize both the retriever and the reader of the models with the weights of Atlas (3B and 11B) and continue to pretrain the model with prefix language modeling. To isolate the effect of retrieval, we do not update the retriever during the training process for prefix language modeling. We pretrain the reader using the December 2021 Wikipedia corpora preprocessed by Izacard et al. (2023  ###reference_b16###), where the index is also constructed using the same corpora. In accordance with Izacard et al. (2023  ###reference_b16###), we retrieve 20 passages for each masked sequence (excluding passages identical to the original sequence). Both the 3B and 11B models are trained for 5,000 steps, using AdamW optimizer (Loshchilov & Hutter, 2019  ###reference_b25###) with a batch size of 64.

The prompts used can be found in Appendix B.4  ###reference_### and Appendix B.5  ###reference_###.\nIn alignment with the pretraining of Atlas, we design the prompt for prefix language modeling as\n{prefix}<extra_id_0> title: {title} context: {text}\nwhere {prefix} represents the prefix of an input sequence. The {title} and {text} elements are retrieved by the model\u2019s retriever using the prefix as a query. Here, {text} signifies the retrieved passage, while {title} denotes the corresponding article and section title of the passage.\nThe model is trained to generate\n<extra_id_0>{suffix}\nwhere {suffix} is the suffix (masked by <extra_id_0>) of the input sequence.\nIn accordance with pretraining, we use the following prompt for open-domain question answering:\nQuestion: {question} Answer:<extra_id_0> title: {title} context: {text}\nFor example,\nQuestion: In which country was the first permanent bungee jumping site situated?

Hackett remains one of the largest commercial operators, with concerns in several countries. Several million successful jumps have taken place since 1980. This safety record is attributable to bungee operators rigorously conforming to standards and guidelines governing jumps, such as double checking calculations and fittings for every jump. As with any sport, injuries can still occur (see below), and there have been fatalities. A relatively common mistake in fatality cases is to use a cord that\nMMLU comprises 57 multiple-choice question answering datasets that span various domains, including elementary mathematics, US history, computer science, and more.\nFor the evaluation on MMLU, we report the accuracy and use an index composed of December 2021 Wikipedia corpora.\nWe follow Izacard et al. (2023  ###reference_b16###) to apply the \u201cde-biased\u201d inference.\nSpecifically, during inference, we execute four forward passes, each corresponding to a cyclic permutation of the answer letter-option assignment within the question. For instance, the answer option designated to letter \u2018A\u2019 is shifted to \u2018B\u2019, \u2018B\u2019 to \u2018C\u2019, \u2018C\u2019 to \u2018D\u2019, and \u2018D\u2019 to \u2018A\u2019. The final prediction is obtained by summing up the probabilities from these four forward passes.\nWe design the prompt in the following format:\nQuestion: {question} Options: {candidate answers} Answer:<extra_id_0> title: {title} context: {text}\nFor example,\nQuestion: Over time, non-volcanic mountains can form due to the interaction of plate boundaries. Which interaction is most likely associated with the formation of non-volcanic mountains? Options: (A) continental plates colliding with continental plates (B) continental plates separating from continental plates (C) oceanic plates colliding with oceanic plates (D) oceanic plates separating from oceanic plates Answer:<extra_id_0> title: ... context: ...\nGiven that many questions in the MMLU benchmark are quite lengthy, concatenating in-context examples (questions and candidate answers) with the target question in a few-shot setting is likely to exceed the maximum input length. To mitigate this, we only sample examples with question lengths of fewer than 50 tokens to use as in-context examples."

Subsequently, by training with prefix language modeling, the mismatch between pretraining and inference is mitigated, resulting in improved zero-shot and few-shot performance.\nTable 7  ###reference_### presents some example outputs of Atlas and Raven 11B on long-form question answering. The questions are sampled from the ELI5 dataset (Fan et al., 2019  ###reference_b10###).\nAn examination of these results reveals that Atlas typically generates concise answers, while the output from Raven generally encompasses more information. This is a predictable outcome given that Atlas is pretrained solely with masked language modeling, where each masked span usually contains only a handful of tokens. Besides, while Raven\u2019s answers are not always entirely accurate, they generally exhibit higher quality compared to Atlas.

+    "title": "The Geometry of Truth: Emergent Linear Structure in LLM Representations of True/False Datasets",
+    "abstract": "Large Language Models (LLMs) have impressive capabilities, but are prone to outputting falsehoods. Recent work has developed techniques for inferring whether a LLM is telling the truth by training probes on the LLM\u2019s internal activations. However, this line of work is controversial, with some authors pointing out failures of these probes to generalize in basic ways, among other conceptual issues. In this work, we use high-quality datasets of simple true/false statements to study in detail the structure of LLM representations of truth, drawing on three lines of evidence: 1. Visualizations of LLM true/false statement representations, which reveal clear linear structure. 2. Transfer experiments in which probes trained on one dataset generalize to different datasets. 3. Causal evidence obtained by surgically intervening in a LLM\u2019s forward pass, causing it to treat false statements as true and vice versa. Overall, we present evidence that at sufficient scale, LLMs linearly represent the truth or falsehood of factual statements. We also show that simple difference-in-mean probes generalize as well as other probing techniques while identifying directions which are more causally implicated in model outputs.",

+            "text": "Despite their impressive capabilities, large language models (LLMs) do not always output true text (Lin et al., 2022  ###reference_b24###; Steinhardt, 2023  ###reference_b35###; Park et al., 2023  ###reference_b28###). In some cases, this is because they do not know better. In other cases, LLMs apparently know that statements are false but generate them anyway. For instance, Perez et al. (2022  ###reference_b30###) demonstrate that LLM assistants output more falsehoods when prompted with the biography of a less-educated user. More starkly, OpenAI (2023  ###reference_b27###) documents a case where a GPT-4-based agent gained a person\u2019s help in solving a CAPTCHA by lying about being a vision-impaired human. \u201cI should not reveal that I am a robot,\u201d the agent wrote in an internal chain-of-thought scratchpad, \u201cI should make up an excuse for why I cannot solve CAPTCHAs.\u201d\nWe would like techniques which, given a language model  and a statement , determine whether  believes  to be true (Christiano et al., 2021  ###reference_b8###). One approach to this problem relies on inspecting model outputs; for instance, the internal chain-of-thought in the above example provides evidence that the model understood it was generating a falsehood. An alternative class of approaches instead leverages access to \u2019s internal state when processing . There has been considerable recent work on this class of approaches: Azaria & Mitchell (2023  ###reference_b3###), Li et al. (2023b  ###reference_b23###), and Burns et al. (2023  ###reference_b6###) all train probes for classifying truthfulness based on a LLM\u2019s internal activations. In fact, the probes of Li et al. (2023b  ###reference_b23###) and Burns et al. (2023  ###reference_b6###) are linear probes, suggesting the presence of a \u201ctruth direction\u201d in model internals.\nHowever, the efficacy and interpretation of these results are controversial. For instance, Levinstein & Herrmann (2023  ###reference_b20###) note that the probes of Azaria & Mitchell (2023  ###reference_b3###) fail to generalize in basic ways, such as to statements containing the word \u201cnot.\u201d The probes of Burns et al. (2023  ###reference_b6###) have similar generalization issues, especially when using representations from autoregressive transformers. This suggests these probes may be identifying not truth, but other features that correlate with truth on their training data.\nWorking with autoregressive transformers from the LLaMA-2 family (Touvron et al., 2023  ###reference_b37###), we shed light on this murky state of affairs. After curating high-quality datasets of simple, unambiguous true/false statements, we perform a detailed investigation of LLM representations of factuality. Our analysis, which draws on patching experiments, simple visualizations with principal component analysis (PCA), a study of probe generalization, and causal interventions, finds:\nEvidence that linear representations of truth emerge with scale, with larger models having a more abstract notion of truth that applies across structurally and topically diverse inputs.\nA small group of causally-implicated hidden states which encode these truth representations.\nConsistent results across a suite of probing techniques, but with simple difference-in-mean probes identifying directions which are most causally implicated.\nOur code, datasets, and an interactive dataexplorer are available at https://github.com/saprmarks/geometry-of-truth  ###reference_ruth###.\n###figure_1###"

Substantial previous work has studied whether LLMs encode world models in their representations (Li et al., 2023a  ###reference_b22###; 2021  ###reference_b21###; Abdou et al., 2021  ###reference_b1###; Patel & Pavlick, 2022  ###reference_b29###). Early work focused on whether individual neurons represent features (Wang et al., 2022  ###reference_b39###; Sajjad et al., 2022  ###reference_b33###; Bau et al., 2020  ###reference_b4###), but features may more generally be represented by directions in a LLM\u2019s latent space (i.e. linear combinations of neurons) (Dalvi et al., 2018  ###reference_b10###; Gurnee et al., 2023  ###reference_b19###; Cunningham et al., 2023  ###reference_b9###; Elhage et al., 2022  ###reference_b11###). We say such features are linearly represented by the LLM. Just as other authors have asked whether models have directions representing the concepts of \u201cWest Africa\u201d (Goh et al., 2021  ###reference_b18###) or \u201cbasketball\u201d (Gurnee et al., 2023  ###reference_b19###), we ask here whether there is a direction corresponding to the truth or falsehood of a factual statement.\nProbing for truthfulness. Others have trained probes to classify truthfulness from LLM activations, using both logistic regression (Azaria & Mitchell, 2023  ###reference_b3###; Li et al., 2023b  ###reference_b23###), unsupervised (Burns et al., 2023  ###reference_b6###), and contrastive (Zou et al., 2023  ###reference_b40###; Rimsky et al., 2024  ###reference_b32###) techniques. This work differs from prior work in a number of ways. First, a cornerstone of our analysis is evaluating whether probes trained on one dataset transfer to topically and structurally different datasets in terms of both classification accuracy and causal mediation of model outputs. Second, we specifically interrogate whether our probes attend to truth, rather than merely features which correlate with truth (e.g. probable vs. improbable text). Third, we localize truth representations to a small number of hidden states above certain tokens. Fourth, we go beyond the mass-mean shift interventions of Li et al. (2023b  ###reference_b23###) by systematically studying the properties of difference-in-mean. Finally, we carefully scope our setting, using only datasets of clear, simple, and unambiguous factual statements, rather than statements which are complicated and structured (Burns et al., 2023  ###reference_b6###), confusing (Azaria & Mitchell, 2023  ###reference_b3###; Levinstein & Herrmann, 2023  ###reference_b20###), or intentionally misleading (Li et al., 2023b  ###reference_b23###; Lin et al., 2022  ###reference_b24###)."

Consider the following prompt :\nThe city of Tokyo is in Japan. This statement is: TRUE \nThe city of Hanoi is in Poland. This statement is: FALSE \nThe city of Chicago is in Canada. This statement is:\nSimilarly, let  be the prompt obtained from  by replacing \u201cChicago\u201d with \u201cToronto,\u201d thereby making the final statement true.

We see three groups of causally implicated hidden states. The final group, labeled (c), directly encodes the model\u2019s prediction: after applying the LLM\u2019s decoder head directly to these hidden states, the top logits belong to tokens like \u201ctrue,\u201d \u201cTrue,\u201d and \u201cTRUE.\u201d The first group, labeled (a), likely encodes the LLM\u2019s representation of \u201cChicago\u201d or \u201cToronto.\u201d\n###figure_2### What does group (b) encode?

Guided by the results of \u00a73  ###reference_###, we present here visualizations of the most downstream hidden state in group (b); for example, for LLaMA-2-13B, we use the layer 15 residual stream activation over the end-of-sentence punctuation token.333Our qualitative results are insensitive to choice of layer among early-middle to late-middle layers. On the other hand, when using representations over the final token in the statement (instead of the punctuation token), we sometimes see that the top PCs instead capture variation in the token itself (e.g. clusters for statements ending in \u201cChina\u201d regardless of their truth value). Unlike in \u00a73  ###reference_###, we do not prepend the statements with a few-shot prompt (so our models are not \u201cprimed\u201d to consider the truth value of our statements). For each dataset, we also center the activations by subtracting off their mean.\nWhen visualizing LLaMA-2-13B and 70B representations of our curated datasets \u2013 datasets constructed to have little variation with respect to non-truth features, such as sentence structure or subject matter \u2013 we see clear linear structure (Fig. 1  ###reference_###), with true statements separating from false ones in the top two principal components (PCs). As explored in App. C  ###reference_###, this structure emerges rapidly in early-middle layers and emerges later for datasets of more structurally complex statements (e.g. conjunctive statements).\nTo what extent does this visually-apparent linear structure align between different datasets? Our visualizations indicate a nuanced answer: the axes of separation for various true/false datasets align often, but not always. For instance, Fig. 3  ###reference_###(a) shows the first PC of cities also separating true/false statements from other datasets, including diverse uncurated datasets. On the other hand, Fig. 3  ###reference_###(c) shows stark failures of alignment, with the axes of separation for datasets and statements and their negations being approximately orthogonal.\nThese cases of misalignment have an interesting relationship to scale. Fig. 3  ###reference_###(b) shows larger_than and smaller_than separating along antipodal directions in LLaMA-2-13B, but along a common direction in LLaMA-2-70B. App. C  ###reference_### depicts a similar phenomenon occuring over the layers of LLaMA-2-13B: in early layers, cities and neg_cities separate antipodally, before rotating to lie orthogonally (as in Fig. 3  ###reference_###(c)), and finally aligning in later layers.\n###figure_3###"

While it is unsurprising that larger models are themselves better at labeling statements as true or false, it is not obvious that linear probes trained on larger models should also generalize better.

This is shown for LLaMA-2-13B in Fig. 7  ###reference_###. We hypothesize that this is due to LLMs hierarchically developing understanding of their input data, progressing from surface level features to more abstract concepts.\nThe misalignment in Fig. 3  ###reference_###(c) also has an interesting dependence on layer. In Fig. 8  ###reference_### we visualize LLaMA-2-13B representations of cities and neg_cities at various layers. In early layers (left) we see antipodal alignment as in Fig. 3  ###reference_###(b, center). As we progress through layers, we see the axes of separation rotate to lie orthogonally, until they eventually align.\nOne interpretation of this is that in early layers, the model computed and linearly represented some feature (like \u201cclose association\u201d) which correlates with truth on both cities and neg_cities but with opposite signs. In later layers, the model computed and promoted to greater salience a more abstract concept which correlates with truth across both datasets.\n###figure_8###"

We formed these statements from the template \u201cThe city of [city] is in [country]\u201d using a list of world cities from Geonames (2023  ###reference_b16###). We filtered for cities with populations , which did not share their name with any other listed city, which were located in a curated list of widely-recognized countries, and which were not city-states. For each city, we generated one true statement and one false statement, where the false statement was generated by sampling a false country with probability equal to the country\u2019s frequency among the true datapoints (this was to ensure that e.g. statements ending with \u201cChina\u201d were not disproportionately true). Example statements:\nThe city of Sevastopol is in Ukraine. (TRUE)\nThe city of Baghdad is in China. (FALSE)\nsp_en_trans. Beginning with a list of common Spanish words and their English translations, we formed statements from the template \u201cThe Spanish word \u2018[Spanish word]\u2019 means \u2018[English word]\u2019.\u201d Half of Spanish words were given their correct labels and half were given random incorrect labels from English words in the dataset. The first author, a Spanish speaker, then went through the dataset by hand and deleted examples with Spanish words that have multiple viable translations or were otherwise ambiguous. Example statements:\nThe Spanish word \u2018imaginar\u2019 means \u2018to imagine\u2019. (TRUE)\nThe Spanish word \u2018silla\u2019 means \u2018neighbor\u2019. (FALSE)\nlarger_than and smaller_than. We generate these statements from the templates \u201cx is larger than y\u201d and \u201cx is smaller than y\u201d for . We exclude cases where  or where one of x or y is divisible by . We chose to limit the range of possible values in this way for the sake of visualization: we found that LLaMA-13B linearly represents the size of numbers, but not at a consistent scale: the internally represented difference between one and ten is considerably larger than between fifty and sixty. Thus, when visualizing statements with numbers ranging to one, the top principal components are dominated by features representing the sizes of numbers.\nneg_cities and neg_sp_en_trans. We form these datasets by negating statements from cities and sp_en_trans according to the templates \u201cThe city of [city] is not in [country]\u201d and \u201c\u2018The Spanish word \u2018[Spanish word]\u2019 does not mean \u2018[English word]\u2019.\u201d\ncities_cities_conj and cities_cities_disj. These datasets are generated from cities according to the following templates:\nIt is the case both that [statement 1] and that [statement 2].\nIt is the case either that [statement 1] or that [statement 2].\nWe sample the two statements independently to be true with probability  for cities_cities_conj and with probability  for cities_cities_disj. These probabilities are selected to ensure that the overall dataset is balanced between true and false statements, but that there is no correlation between the truth of the first and second statement in the conjunction.\nlikely. We generate this dataset by having LLaMA-13B produce unconditioned generations of length up to  tokens, using temperature .

CommonClaim was introduced in Casper et al. (2023  ###reference_b7###). It consists of various statements generated by GPT-3-davinci-002, labeled by humans as being true, false, or neither. If human labelers disagreed on the truth of a statement, this is also recorded. We adapted CommonClaim by selecting statements which were labeled true or false with no labeler disagreement, then removing excess true statement to balance the dataset. Example statements:\nTomatoes are not actually a vegetable. (TRUE)\nContrary to popular belief, the platypuses are not venomous. (FALSE)\nAs these examples show, the statements can be ambiguous or of unclear truth value.\ncounterfact_true_false. Counterfact was introduced in Meng et al. (2022  ###reference_b25###) and consists of factual recall statements. We adapt Counterfact by using statements which form complete sentences and, for each such statement, using both the true version and a false version given by one of Counterfact\u2019s suggested false modifications. We also append a period to the end. Example statements:\nOlaus Rudbeck spoke the language Swedish. (TRUE)\nThe official religion of Malacca sultanate is Christianity. (FALSE)"

A classic result by Bshouty-Tamon (J. ACM 1996) proved that monotone functions can be learned with  samples and it is not hard to show that this bound extends to testing. Prior to our work the only lower bound for this problem was  in the small  parameter regime, when , due to Goldreich-Goldwasser-Lehman-Ron-Samorodnitsky (Combinatorica 2000). Thus, the sample complexity of monotonicity testing was wide open for . We resolve this question, obtaining a nearly tight lower bound of  for all  at most a sufficiently small constant. In fact, we prove a much more general result, showing that the sample complexity of -monotonicity testing and learning for functions  is . For testing with one-sided error we show that the sample complexity is .",

Monotone and -monotone Boolean functions over domains , , and  have been the focus of a significant amount of research in property testing and computational learning theory. We give an overview of the literature in Section 1.4  ###reference_###.\nThe field of property testing is concerned with the design and analysis of sub-linear time randomized algorithms for determining if a function has, or is far from having, some specific property. A key aspect in the definition of a property testing algorithm is the type of access it has to the function. Early works on property testing, e.g. [RS96  ###reference_bx61###, GGR98  ###reference_bx44###], focused on the notion of query-based testers, which are allowed to observe the value of the function on any point of their choosing, and since then this has become the standard model. The weaker notion of sample-based testers, which can only view the function on independent uniform samples, was also considered by [GGR98  ###reference_bx44###] and has received some attention over the years, see e.g. [KR00  ###reference_bx53###, BBBY12  ###reference_bx4###, FLV15  ###reference_bx41###, GR16  ###reference_bx46###, FH23  ###reference_bx37###, FH24  ###reference_bx38###]. Sample-based algorithms are considered more natural in many settings, for example in computational learning theory, where they are the standard model. In fact, sample-based testing and learning are closely related problems; given a learning algorithm, it is always possible to design a testing algorithm with the same sample complexity, up to an additive  factor111See Lemma C.1  ###reference_theorem1### for a precise statement. Also, note that if the learning algorithm is proper, then the time complexity is also preserved. If the learning algorithm is improper, then there is a time complexity blow-up, but the sample complexity is still preserved..\nFor many fundamental properties, there is still a large gap between how much we know in the query-based vs the sample-based models. Monotonicity (and -monotonicity) is such a property; despite a vast body of research on query-based monotonicity testing over the hypercube , the only work we know of which considers this problem in the sample-based model is [GGL+00  ###reference_bx43###], who gave an upper bound of  and a matching lower bound for the case when  on the number of samples needed to test monotonicity of functions . The upper bound for learning monotone Boolean functions due to [BT96  ###reference_bx22###, LRV22  ###reference_bx56###] also implies a testing upper bound of . Thus, this question has been wide open for .\nOur work addresses this gap in the monotonicity testing literature, proving a lower bound which matches the learning upper bound for all  at most some constant, up to a factor of  in the exponent. More generally, we prove a nearly tight lower bound for -monotonicity testing of functions, , i.e. functions with image size at most . To round out our results, we also give an improved learning algorithm for -monotone functions over  under product distributions whose sample complexity matches our sample-based testing lower bound, up to poly-logarithmic factors in the exponent."

Very recently, they have also been used to prove lower bounds for tolerant monotonicity testing [CDL+24  ###reference_bx25###] and for testing convexity of sets in  [BBH24  ###reference_bx5###].\nTo understand our construction, let us first consider the special case of monotonicity of Boolean functions, i.e.  and . We think of a DNF term as a point  which is said to be satisfied by  if , where  denotes the standard bit-wise partial order over . The width of a term  is its Hamming weight, , and the width of a DNF is the max width among its terms. Consider  randomly chosen terms  each of width . We will see later how to choose  and . Let  and for each , let\nbe the set of points in  which satisfy  and no other terms. Let . Now observe that any two points lying in different \u2019s are incomparable and therefore independently embedding an arbitrary monotone function into each  will result in a function which globally is monotone if one defines the function outside of  appropriately. Using this fact we can define two distributions  and  as follows. Let  denote the set of points in  for which either  or  and  for two different terms .\nis drawn by setting  if and only if  where  contains each  with probability , independently. Such a function is always monotone.\nis drawn by setting  if and only if  where  contains each  with probability , independently. Such a function will be -far from monotone with probability  since its restriction with  is uniformly random.\nNow, each  satisfies  and for both distributions the events  and  are independent when  lie in different \u2019s. Therefore, any tester will need to see at least two points from the same  to distinguish  and . Roughly speaking, by birthday paradox this gives a  lower bound on the number of samples. The lower bound is thus determined by the maximum number of terms  that can be used in the construction for which .\nSo how are  and  chosen? By standard concentration bounds, we have  and observe that a point  satisfies a random term with probability exactly . We need  to contain a constant fraction of , i.e. we need  to satisfy exactly  term with constant probability. The expected number of satisfied terms is  and, roughly speaking, we need this value to be  for all . Applying this constraint to the case when  forces us to pick . Now when , the expected number of satisfied terms is  and we are forced to choose . The lower bound for sample-based monotonicity testing of  is then .\nLet us now think about generalizing this construction to testing -monotonicity of functions . The moral of the above argument is that the permitted number of terms is controlled by the number of distinct Hamming weights in the set . We observe that for larger values of  and  we can partition  into  blocks as  each with a window of Hamming weights of size only . We are able to essentially repeat the above construction independently within each block wherein we can set  and consequently .\nFor each block , the random Talagrand DNF within block  is defined analogously to the above construction, except that it assigns function values from , instead of . See Fig.\u20091  ###reference_### for an illustration. Since there are  blocks in total, the distribution  only produces -monotone functions. At the same time, a function  assigns uniform random  values within each block . This results in a large number of long chains through  which alternate between function value  and .

Sample-based monotonicity testing of functions on the line  was studied by [PRV18  ###reference_bx58###] who gave a one-sided error upper bound of  and a matching lower bound of  for all sample-based testers.\nMonotonicity testing has been extensively studied in the standard query model [Ras99  ###reference_bx59###, EKK+00  ###reference_bx35###, GGL+00  ###reference_bx43###, DGL+99  ###reference_bx34###, LR01  ###reference_bx55###, FLN+02  ###reference_bx40###, HK03  ###reference_bx47###, AC06  ###reference_bx1###, HK08  ###reference_bx48###, ACCL07  ###reference_bx2###, Fis04  ###reference_bx39###, SS08  ###reference_bx62###, Bha08  ###reference_bx15###, BCSM12  ###reference_bx12###, FR10  ###reference_bx42###, BBM12  ###reference_bx6###, RRSW11  ###reference_bx60###, BGJ+12  ###reference_bx14###, CS13  ###reference_bx29###, CS14a  ###reference_bx30###, CST14  ###reference_bx32###, BRY14a  ###reference_bx20###, BRY14b  ###reference_bx21###, CDST15  ###reference_bx26###, CDJS15  ###reference_bx24###, KMS15  ###reference_bx51###, BB16  ###reference_bx3###, CWX17  ###reference_bx33###, BCS18  ###reference_bx8###, PRV18  ###reference_bx58###, BCS20  ###reference_bx9###, HY22  ###reference_bx49###, BKR24  ###reference_bx17###, BKKM23  ###reference_bx16###, BCS23b  ###reference_bx11###, BCS23a  ###reference_bx10###, CDL+24  ###reference_bx25###]. When discussing these works we treat  as a small constant for brevity. For , the non-adaptive query complexity has been established at  [KMS18  ###reference_bx52###, CWX17  ###reference_bx33###] with an adaptive lower bound of  [CWX17  ###reference_bx33###]. This gap for adaptive monotonicity testing of Boolean functions is still an outstanding open question. For  and  under product measures, a recent result of [BCS23a  ###reference_bx10###] established a non-adaptive upper bound of . For functions , [BKR24  ###reference_bx17###] showed upper and lower bounds of  for non-adaptive, one-sided error testers and there is a general (adaptive) lower bound of  due to [BBM12  ###reference_bx6###]. For real-valued functions , the query complexity is known to be . The upper bound is non-adaptive [CS13  ###reference_bx29###] and the lower bound holds even for adaptive testers [CS14b  ###reference_bx31###].\nThe generalization to -monotonicity testing has also been studied in the standard query model by [GKW19  ###reference_bx45###, CGG+19  ###reference_bx28###]. These works show that the query-complexity of non-adaptive one-sided error -monotonicity testing is  for all , demonstrating an interesting separation between (1-)monotonicity and 2-monotonicity.\nMonotone Boolean functions  were studied in the context of learning theory by [BT96  ###reference_bx22###] who showed that they can be (improperly) learned to error  under the uniform distribution with  time and samples. Very recent works [LRV22  ###reference_bx56###, LV23  ###reference_bx57###] have given agnostic proper learning algorithms with the same complexity.\nThe result of [BT96  ###reference_bx22###] was generalized by [BCO+15  ###reference_bx7###] who gave upper and lower bounds of  for learning -monotone Boolean functions . For Boolean functions over hypergrids , [CGG+19  ###reference_bx28###] gave an upper bound of  where  hides polylog factors of . This result was generalized to functions  under product measures by [HY22  ###reference_bx49###].\nThe notion of sample-based property testing was first presented and briefly studied by [GGR98  ###reference_bx44###]. Broader studies of sample-based testing and its relationship with query-based testing have since been given by [FGL14  ###reference_bx36###, FLV15  ###reference_bx41###, GR16  ###reference_bx46###]. A characterization of properties which are testable with a constant number of samples was given by [BY19  ###reference_bx23###].\nAs we mentioned, sample-based algorithms are the standard model in learning theory, and learning requires at least as many samples as testing for every class of functions. Thus, it is natural to ask, when is testing easier than learning in terms of sample complexity? This question is referred to as testing vs learning and has been studied by [KR00  ###reference_bx53###] and more recently by [BFH21  ###reference_bx13###, FH23  ###reference_bx37###, FH24  ###reference_bx38###].\nThere has also been work studying models that interpolate between query-based and sample-based testers. For instance, [BBBY12  ###reference_bx4###] introduced the notion of active testing, where the tester may make queries, but only on points from a polynomial-sized batch of unlabeled samples drawn from the underlying distribution. This was inspired by the notion of active learning which considers learning problems under this access model.\nSample-based convexity testing of sets over various domains has also seen some recent attention [CFSS17  ###reference_bx27###, BMR19a  ###reference_bx18###, BMR19b  ###reference_bx19###, BBH24  ###reference_bx5###]."

+    "abstract": "The realistic rendering of woven and knitted fabrics has posed significant challenges throughout many years. Previously, fiber-based micro-appearance models have achieved considerable success in attaining high levels of realism. However, rendering such models remains complex due to the intricate internal scatterings of hundreds of fibers within a yarn, requiring vast amounts of memory and time to render. In this paper, we introduce a new framework to capture aggregated appearance by tracing many light paths through the underlying fiber geometry. We then employ lightweight neural networks to accurately model the aggregated BSDF, which allows for the precise modeling of a diverse array of materials while offering substantial improvements in speed and reductions in memory. Furthermore, we introduce a novel importance sampling scheme to further speed up the rate of convergence. We validate the efficacy and versatility of our framework through comparisons with preceding fiber-based shading models as well as the most recent yarn-based model.",

Fabrics, with their detailed structure of fibers, plies, and yarns, present a unique hierarchical geometric structure at each aggregation level, offering a wide array of appearances for different cloth types.\nThe challenge of accurately modeling the detailed geometry and scattering of fabrics has led to the development of different methods, mainly split into curve-based and surface-based shading models. Curve-based models, using the Bidirectional Curve Scattering Distribution Function (BCSDF), aim to explicitly represent individual elements like fibers [khungurn2015matching], plies [montazeri2020practical] and yarns [Zhu2023yarn], similar to methods used in hair rendering. However, these models, while accurate, face challenges like long rendering times and high storage needs.\nMicro-appearance models focus on representing fabrics at the microscale, detailing each fiber using high-resolution volumes or fiber meshes [zhao2011building]. These models are great at rendering with high detail but are limited in practical use due to their data-intensive nature and their challenges in manipulation and rendering.\nIn contrast, surface-based models, which depict fabric as a 2D sheet and use specific reflectance models for appearance, are known for being lightweight and user-friendly e.g. [sadeghi2013practical]. These models, widely used in the computer graphics industry, can accurately reproduce the overall appearance of fabrics. However, they often fail to capture the fine details necessary for realistic close-up images.\nIn this paper, we aim to combine the light scattering of a twisted yarn, made up of hundreds of fibers, by simulating the paths of many light rays into the yarn and analyzing their scattering properties. From this analysis, we show that the scattering can be described as three distinct components, and we introduce a new way to model each component using various neural networks and analytical solutions. Additionally, we derive an analytical importance sampling scheme that closely matches the combined scattering distribution. We demonstrate that our model is able to run up to 23 times faster while using up to 600 times less memory when compared to previous fiber-based methods. The memory gain is directly dependent on the fiber count which is often a few hundred. In summary, our main contributions include:\nWe introduce a novel neural framework for modeling the light scattering within a bundle of fibers in the yarns. By dividing the scattering into components, we can efficiently model various types of yarns across a broad range of parameters. Our proposed method runs significantly faster and uses substantially less memory.\nWe further improve on existing neural network approaches by using the channel-wise PReLU activation function to increase performance. We demonstrate its effectiveness by comparing its performance against various model architectures.\nFrom our observations, we derive a new analytical fitting of the scattering for importance sampling. We have managed to derive a new observation-based empirical and invertible importance sampling scheme that matches the scattering distribution to further accelerate the rate of convergence."

Traditional models have often depicted cloth as 2D surfaces, utilizing Bidirectional Reflectance Distribution Functions (BRDFs) or Bidirectional Texture Functions (BTFs) to illustrate light-cloth interactions [sattler2003efficient, adabala2003, irawan2012specular, sadeghi2013practical, rainer2019neural, kuznetsov2021neumip, jin2022woven, zhu2023realistic]. While these surface-based models are lightweight and capable of producing high-quality results at mid-to-far distances, they typically lack the fine-grained details necessary for close-up views.\nMicro-appearance Cloth Models - On the contrary, micro-appearance models have emerged, focusing on the fabric\u2019s micro-geometry down to the fiber level, offering a high fidelity and detail [schroder2011volumetric, zhao2011building, khungurn2015matching, loubet2018, Montazeri2021mechanics, aliaga2017appearance]. However, the high complexity of these models presents a significant challenge in rendering them efficiently. Various precomputation-based rendering methods have been developed to address this, such as the techniques proposed by [zhao2013modular, khungurn2017fast, luan2017fiber] to improve performance and GPU-based methods developed by [Wu2017realtime] for procedurally generated fabrics. Nevertheless, these methods often compromise either on performance or physical accuracy, as well as being difficult to edit and render.\nAggregation Based Techniques - In recent years, aggregation-based methodologies have been introduced to the domain of cloth rendering, aiming to model the multiple scatterings of a bundle of fibers implicitly. Montazeri et al. [montazeri2020practical, montazeri2021practical] pioneered an aggregated technique that encapsulates the light scatterings of individual fibers, approximating the overall appearance at the ply level for woven and knitted fabrics, respectively; later followed by the yarn-level extension [khattar2024multiscale]. However, their model, while being fast and practical, is predominantly observation-driven and not efficient for yarns with a high number of plies.\nZhu et al. [Zhu2022fur] advanced the field by proposing a technique to aggregate the scatterings of a bundle of straight fur fibers in a data-driven manner. They then parameterize the aggregated scattering by fitting analytical lobes, followed by the training of a neural network to predict the parameters for the lobes. This model does not accommodate twisted fibers and, being a far-field model, cannot represent yarn-level highlights at close-up views. In a subsequent study [Zhu2023yarn], the authors introduced an analytical solution designed to accurately approximate the multi-scattering of yarn by utilizing dual scattering theory. However, this model relies heavily on the assumptions inherited from dual scattering theory and also imposes additional assumptions on the fiber shading model. In contrast, our work, while employing similar fiber scattering models and micro-geometry, presents a more generalized model capable of fitting any yarn without necessitating specific assumptions.\nNeural BRDF Representation - [chen2020ibrdf, sztrajman2021nbrdf] was one of the firsts to leverage machine learning to represent BRDFs and achieve a high compression rate while preserving the fidelity of the BRDF. In this paper, we improve on Sztrajman et al.\u2019s [sztrajman2021nbrdf] framework to support aggregated yarn scattering, as we demonstrate that using their framework in a na\u00efve manner do not produce optimal results."

The normal of the frame is aligned with the normal of the cylinder surface, while the tangent of the frame is aligned in the direction of the yarn tangent. We chose this in contrast to existing hair literature, where a longitudinal angle  and an azimuthal offset  are used, to make the process of finding the surface fiber shading frame easier.

We aggregate the yarn scattering by simulating many light rays into the yarn and recording their exiting radiance and direction to obtain the Radiance Distribution Map (RDM). The RDM is a 4-dimensional map of the exiting radiance for a given  and  and is parameterized by , . Further details on obtaining the RDM are given in \u00a75.3  ###reference_###. We then propose a framework to model the RDM by observation and analysis and split the RDM into 3 components to model them individually.\nIt might intuitively seem advantageous to model the RDM directly by fitting a neural network to it. However, our experiments suggest that this approach is not optimal. Initially, it was observed that at certain incoming angles, specifically at grazing azimuthal angles, a substantial amount of light traverses through the yarn cylinder without interacting with any fibers. In such instances, most of the light is directly transmitted and exhibits Dirac delta distributions, resulting in the corresponding RDM displaying sharp lobes with pronounced peak values. Such distributions pose a significant learning challenge for the neural network due to their high values.\nFurthermore, a considerable fraction of the brightness within the RDM is attributed to the paths characterized by a single bounce. These paths, interacting with a single fiber on the yarn\u2019s surface before exiting, create the highlights of the yarn and introduce abrupt alterations in brightness within the RDM. By isolating these paths into a distinct component, we achieved more precise highlights and facilitated the learning process for the neural network regarding the remaining data. Consequently, we introduce the subsequent shading model as a mixture of separate components T, R, and M, corresponding to the Direct Transmission Component, Direct Reflection Component, and Multi-Scattering Component respectively:\nwhere the T component models the light paths that directly pass through the yarn without intersecting many fibers, the R component models the light paths that hit a single fiber and are reflected away, and the M component models the multiple scattering of light within the yarn before exiting. The components T and M are more complex and hence modelled by a neural network, while the R component can be found analytically. By splitting the shading model into separate components, we can better fit each lobe more accurately, whilst using fewer parameters for the neural network, increasing computational efficiency.

It is important to employ an advanced importance sampling scheme to reduce variance as showcased in Fig. 3  ###reference_###. Nonetheless, due to the complexity of light scattering within a yarn when utilizing a neural network in our approach, we are precluded from using the Bidirectional Scattering Distribution Function (BSDF) for importance sampling. Consequently, we chose to fit an invertible analytical approximation of the data to enhance the sampling of the distribution. Sztrajman et al. [sztrajman2021nbrdf] utilized Blinn-Phong lobes to fit the distribution of their Neural BRDFs. However, given that the scattering of light within a yarn does not center around the half angle, the Blinn-Phong lobe is a poor fit for our model. From our observations of the multi-scattering component, we found that the light mainly scatters around the upper half of the cone centered at the fiber tangent at the yarn surface. Thus, we propose the following importance sampling scheme:\nSample lobe  - We sample the lobes proportional to the energy of their lobes. Since  is comprised of light passing-through with a probability of , the proportion of energy can be described as  directly. The remaining portion of samples can be split proportionally according to the energy of  and , which can be approximated by a constant  which is pre-computed beforehand based on the computed RDM.\nSample outgoing direction - For the direct transmission component, we sample in the direction  to simulate the light passing through the yarn. The direct reflection is sampled similarly to the fiber\u2019s distribution on the yarn surface. It is done by sampling the longitudinal angles via a normalized Gaussian around  with the standard deviation corresponding to the fiber reflection\u2019s longitudinal roughness , while the azimuthal angle is uniformly distributed on the upper cone in the range .\nThe remaining multi-scattering component is sampled via two lobes which are derived from careful observations of the RDM. The first lobe is comprised of a distribution similar to the direct reflection component but with a different longitudinal and azimuthal roughness. It is defined by a longitudinal Gaussian distribution  and azimuthal von Mises distribution , where azimuthal angle is zero at n. The second distribution is described by a simple uniform sphere to capture the remaining directions not covered by the first lobe. The two lobes are split with a parameter . The parameters , , and  are to be fitted beforehand.\nCompute the PDF - The PDF can be described as a mixture of the lobes and can be computed as:\nHere, the PDF for each component is defined as:\nwith their proportions:\nwhere  represents a Gaussian normalized in the range  with mean  and standard deviation .  represents the von Mises distribution with mean  and roughness ."

Beyond the enhancements described in \u00a74  ###reference_### to boost the neural network\u2019s performance, we have also refined their base architecture to achieve higher accuracy with minimal runtime costs by employing the channel-wise Parametric Rectified Linear Unit (PReLU) [he2015prelu] activation function instead of the Rectified Linear Unit (ReLU) [nair2010relu] activation presented in their paper.

The \"dying ReLU\" problem refers to the phenomenon where neurons in a network become inactive and only output zero during training, essentially ceasing to learn or update and thereby reducing the capacity of the model. This often occurs when a large gradient flows through a ReLU neuron, updating the weights in such a way that the neuron will always output zero. PReLU helps to avoid this issue by maintaining active learning and adapting its negative slope to the learned features of the input data.\nAdditionally, We chose the channel-wise PReLU activation function over ReLU because it introduces additional trainable parameters for the negative values of ReLU, allowing the neural network more flexibility to overfit with nearly no extra runtime cost, while avoiding the instability of the dying ReLU problem, which is more prevalent in smaller neural networks.

Based on our experiments, this is true for most fabrics except for fibers with very high albedo (such as cotton with 0.999) as they exhibit significantly more bounces per sample and hence travel more throughout the yarn, causing the exit point to be far from the the enter point. While this assumption satisfies most of our cloth types, we left a more accurate distribution of the exit point as a future study. Furthermore, our model assumes the appearance of the yarn is not spatially varying, and is unable to handle spatially varying yarn colors such as dyed cloth. Lastly, our model requires re-training to alter the yarn parameters, which might limit its use in interactive design and modelling for artists.\nFuture Works - Besides addressing the limitations above, a straightforward extension can include the training and fitting of more complex fiber distributions and scattering as the neural network has the potential to learn any complex distributions. Additionally, we would like to develop and leverage an auto-encoder architecture similar to [sztrajman2021nbrdf] to instantly interpolate our fitted yarn models with different fiber parameters to provide additional flexibility to designers and artists. Although our model performs well with an analytically fitted importance sampling lobe, we are interested in seeing if neural importance sampling methods could be used to further improve convergence [xu2023neusample]. We also would like to extend our method to support efficient level-of-detail simplification. This involves simplifying our model into a 3-dimensional BCSDF using a smaller neural network for far-field views, specifically when the width of the yarn is less than a pixel.\nConclusions - In this paper, we presented a novel aggregated shading framework by leveraging the flexibility and generality of neural networks to model the light interactions with a bundle of fibers i.e. ply. Our model can replicate the appearance of many fabrics while running significantly faster and requiring less memory. Through observations of the RDM, we also derived an analytical approximation and importance sampling scheme to further improve the rate of convergence of our model. Finally, our fitted model can be applied to any yarn geometry instantly, providing greater flexibility in designing fabrics."

+    "title": "DomainForensics: Exposing Face Forgery across Domains via Bi-directional Adaptation",
+    "abstract": "Recent DeepFake detection methods have shown excellent performance on public datasets but are significantly degraded on new forgeries. Solving this problem is important, as new forgeries emerge daily with the continuously evolving generative techniques. Many efforts have been made for this issue by seeking the commonly existing traces empirically on data level. In this paper, we rethink this problem and propose a new solution from the unsupervised domain adaptation perspective. Our solution, called DomainForensics, aims to transfer the forgery knowledge from known forgeries (fully labeled source domain) to new forgeries (label-free target domain). Unlike recent efforts, our solution does not focus on data view but on learning strategies of DeepFake detectors to capture the knowledge of new forgeries through the alignment of domain discrepancies. In particular, unlike the general domain adaptation methods which consider the knowledge transfer in the semantic class category, thus having limited application, our approach captures the subtle forgery traces. We describe a new bi-directional adaptation strategy dedicated to capturing the forgery knowledge across domains. Specifically, our strategy considers both forward and backward adaptation, to transfer the forgery knowledge from the source domain to the target domain in forward adaptation and then reverse the adaptation from the target domain to the source domain in backward adaptation. In forward adaptation, we perform supervised training for the DeepFake detector in the source domain and jointly employ adversarial feature adaptation to transfer the ability to detect manipulated faces from known forgeries to new forgeries. In backward adaptation, we further improve the knowledge transfer by coupling adversarial adaptation with self-distillation on new forgeries. This enables the detector to expose new forgery features from unlabeled data and avoid forgetting the known knowledge of known forgery. Extensive experiments demonstrate that our method is surprisingly effective in exposing new forgeries, and can be plug-and-play on other DeepFake detection architectures.",

+            "text": "The ever-growing convolutional neural network (CNN) based generative models [1  ###reference_b1###, 2  ###reference_b2###, 3  ###reference_b3###, 4  ###reference_b4###, 5  ###reference_b5###, 6  ###reference_b6###] have made face forgery much easier than ever before, allowing people to manipulate the face\u2019s identity, appearance and attributes in high realism with little effort. These CNN-based face forgery techniques, known as DeepFake, have drawn much attention, as their abuse using can lead to impersonation videos, economic fraud, biometric attacks, and even national security problems [7  ###reference_b7###]. Thus, it is urgent and important to counteract the misuse of DeepFakes.\n###figure_1### During the past few years, large number of DeepFake detection methods [8  ###reference_b8###, 9  ###reference_b9###, 73  ###reference_b73###, 72  ###reference_b72###, 10  ###reference_b10###, 11  ###reference_b11###, 12  ###reference_b12###] have emerged. Trained on the recently proposed large DeepFake datasets, such as FaceForensics++ (FF++) [13  ###reference_b13###] and Celeb-DF [14  ###reference_b14###], these detection methods have shown promising performance. However, these methods fall into the category that the training and testing sets are from the same distribution, e.g., the same type of forgery or the same dataset, which unfortunately limits their practical applications, as there are always new types of forgeries emerging continuously and widespreading to everywhere on various social platforms. These new types of forgeries are very unlikely to have been included in the existing datasets, and thus they are unseen to these detectors, causing significant performance degradation (see Fig. 1  ###reference_### top part). This circumstance gives rise to a big challenge to DeepFake detectors, that is, how to detect constantly emerging new forgeries.\nRecently, attempts have been made in the literature to solve this issue. One typical line of research is to use a variety of data augmentation to increase the generalization ability [15  ###reference_b15###, 16  ###reference_b16###, 17  ###reference_b17###, 18  ###reference_b18###]. These methods usually create forged faces by augmenting the pristine videos to cover the known types of forgeries as much as possible. Despite of the promisingly improved generalization, the types of augmentation are limited to known forgeries, thus hindering the performance when confronting unseen forgeries. Frequency clue is also used to improve generalization ability [19  ###reference_b19###, 20  ###reference_b20###, 21  ###reference_b21###, 22  ###reference_b22###]. However, this clue is easily affected by data processing and highly correlated with video quality, which cannot perform consistently across different datasets. A different direction of research is to apply transfer learning, such as zero- and few-shot learning [23  ###reference_b23###, 24  ###reference_b24###, 25  ###reference_b25###], to improving generalization on new forgeries. Since zero-shot learning cannot access the samples of new forgeries in training, its performance is highly suppressed. In contrast, few-shot learning methods relax the restrictions in that they can access a few samples of new forgeries in training. However, this requires the annotation of these samples, which may not be easily obtained in practice, as we may not know whether a face is forged or not, e.g., multiple faces are in view but only video-level labels are provided. Thus, a fundamental question is: can we detect new forgeries by only accessing target samples without any labels, while achieving competitive performance?\nIn this paper, we cast DeepFake detection into a new formulation as an unsupervised domain adaptation problem, by transferring the knowledge from the source domain to the target domain, without using any annotations of target samples in training. This is very different from the existing strategies and it offers significant advantages over them. Specifically, for DeepFake detection, we can treat the known forgeries as the source domain and new forgeries as the target domain, see Fig. 1  ###reference_### bottom part. Our goal is to push the DeepFake detector to learn the common forgery features across different domains by only using label-free interested video collections. It is worth noting that this DeepFake detection problem has a significant discrepancy with the general unsupervised domain adaptation problem, as we aim to learn the common forgery feature from the same category of faces (real or fake), which is more subtle than the semantic features of different categories in the general unsupervised domain adaptation problem (e.g., cat, dog, etc.). To this end, we propose a new unsupervised domain adaptation framework, called DomainForensics, for DeepFake detection. The key to our DomainForensics is a novel bi-directional adaptation strategy. This is very different from the existing DeepFake detection framework which only considers one direction to learn the knowledge supervised by the source domain and transfer it to the target domain. However, since the forgery features are subtle, the one-directional adaptation will inevitably lose a certain amount of knowledge [26  ###reference_b26###, 27  ###reference_b27###, 28  ###reference_b28###], thus limiting the achievable performance on the target domain. To overcome this problem, we design bi-directional adaptation, which first transfers the knowledge from the source domain to the target domain, referred to as forward adaptation, and then reverses the adaptation from the target domain to the source domain, called backward adaptation. The backward adaptation stage utilizes the results of the forward adaptation stage, further explores the knowledge from the target domain, and transfers it back to the source domain. With the mutual adaptation, DeepFake detector can fully grab the common forgery features across domains.\nTo verify our idea, we adopt Vision Transformer (ViT) [29  ###reference_b29###] as our DeepFake detector in the experiment, due to its successful application on vision tasks. Other architectures, such as ResNet [30  ###reference_b30###], Xception [31  ###reference_b31###] and EfficientNet [32  ###reference_b32###], can also be used in our framework, and this will also be demonstrated. Since the frequency space can reveal the forgery traces [19  ###reference_b19###, 20  ###reference_b20###], we use color images and corresponding frequency-transformed maps as the input. In the forward adaptation stage, we develop a discriminator that is trained together with the DeepFake detector in an adversarial manner, where the discriminator aims to tell which domain the learned feature is from, and the DeepFake detector aims to extract features that confuse the discriminator. By doing so, the distribution of the target domain is pulled close to the source domain. In the backward adaptation stage, the adaptation is reverted. Since no labels are provided, we employ self-distillation [27  ###reference_b27###] to further excavate the knowledge of the target domain, and then apply the adversarial training to the distilled model, in order to transfer the knowledge back to the source domain. Extensive experiments are conducted on FF++ and Celeb-DF datasets in several cross-domain scenarios, including different manipulation methods, datasets and types, to demonstrate the effectiveness of our method.\nThe contribution of this work is summarized as follows.\nWe propose a new DeepFake detection solution called DomainForensics to handle continuously emerged new forgeries. Different from recent efforts, our method focuses on pushing the detectors to learn the common forgery features across domains, that is, to transfer the forgery knowledge from known forgeries to unseen forgeries, instead of empirically blending faces on the data level.\nWe propose a new bi-directional adaptation strategy, which first transfers the forgery knowledge from the source domain to the target domain in forward adaptation, and then reverses the adaptation from the target domain to the source domain in backward adaptation. Since the forgery traces are very subtle, we design the backward adaptation stage to further refine the results obtained from the forward adaptation stage with a self-distillation scheme.\nExtensive experiments are conducted on FF++ and Celeb-DF datasets with several cross-domain scenarios, including crossing manipulation methods, crossing datasets, and crossing generative types, to demonstrate the effectiveness of our method. We also study the effects of various adaptation settings, various amounts of training samples and different components, to provide thoughtful insights for the following research.\nThe remainder of this paper is organized as follows.

Section III  ###reference_### details our proposed DomainForensics, including the problem formulation, network framework and bi-directional adaptation.

One challenging problem in this task is how to detect constantly emerging new forgeries. The methods [15  ###reference_b15###, 16  ###reference_b16###, 17  ###reference_b17###, 18  ###reference_b18###, 35  ###reference_b35###, 38  ###reference_b38###, 74  ###reference_b74###] enhance generalization ability by exploring elaborate augmentations on pristine videos, with the aim of covering most of the known forgery types. The limitation of these methods is that the augmentation diversity is restricted to known forgeries. Hence, these methods can hardly handle unknown forgeries. Another vein of methods [19  ###reference_b19###, 20  ###reference_b20###, 21  ###reference_b21###, 10  ###reference_b10###, 22  ###reference_b22###, 39  ###reference_b39###, 40  ###reference_b40###] utilize frequency features to improve generalization ability.

Inspired by transfer learning, the methods [23  ###reference_b23###, 24  ###reference_b24###, 25  ###reference_b25###, 37  ###reference_b37###] employ zero-shot and few-shot learning to detect new forgeries. Since zero-shot learning cannot access the samples of new forgeries, its performance gain is severely limited. The few-shot learning needs a small portion of samples and corresponding labels of new forgeries. However, although the video-level label is easily obtained, the face-level label is extremely difficult to obtain in practice."

+            "text": "Unsupervised domain adaptation (UDA) aims to address the challenge of transferring knowledge from a source domain to a target domain when labeled data is scarce or completely absent in the target domain. Ben-David et al. [42  ###reference_b42###] theoretically revealed that the cross-domain common features serve as latent representations that encapsulate shared and domain-common features across diverse domains. The primary objective is to diminish or eliminate domain-specific variations while retaining domain-agnostic information. The acquisition of cross-domain common representation enhances the model\u2019s reliability to domain shifts by prioritizing task-relevant information that transcends domain-specific discrepancies. Consequently, the model achieves improved generalization to unlabeled target domains, even in the scenarios with limited available data.\nThe existing works for addressing UDA can be classified to two main forms, namely, the discrepancy-based approach and the adversarial approach. Concretely, discrepancy-based methods encourage the model to align the domain discrepancy by minimizing the metrics that can measure the distribution discrepancy between the source and target domains [43  ###reference_b43###, 44  ###reference_b44###, 45  ###reference_b45###, 46  ###reference_b46###]. Inspired by the success of generative adversarial network (GAN) [47  ###reference_b47###], recently developed works employed extra adversarial discriminator to align the domain discrepancy, as the feature distributions of source and target domains can be matched by means of confusing the discriminator [48  ###reference_b48###, 49  ###reference_b49###, 50  ###reference_b50###]. In addition, some state-of-the-art methods build up the feature extractor based on modern transformer structure [51  ###reference_b51###, 52  ###reference_b52###, 53  ###reference_b53###], which demonstrates that UDA not only helps traditional CNNs to improve the generalization but also is profitable for transformer-based networks. This motivates us to treat the transformer networks as the cornerstone structure and further explore effective UDA methods for face forgery detection.\nNote that the general UDA task targets transferring the knowledge of the semantic class category. By contrast, our approach differs from the aforementioned UDA methods in that we aim to explore the subtle forgery features in the face category only. We also find that the existing adaptation schemes, which only consider the adaptation from the source domain to the target domain, is unlikely to perform well on our task. In contrast, our proposed bi-directional adaptation strategy can further explore the knowledge from the unlabeled data in the target domain, as such mutual adaptation coupled with knowledge transfer with self-distillation enables the model to learn common forgery features across known and new forgeries. To the best of our knowledge, Chen and Tan [54  ###reference_b54###] is the first work that attempted to solve Deepfake detection using unsupervised domain adaptation. However, it is a trivial usage of a naive existing solution without improvement, and hence the detection performance is not satisfied. By contrast, our DomainForensics adopts a meticulously designed strategy, named bi-directional adaptation, which can fully learn the common forgery features across domains and it is validated under several practical cross-domain scenarios."

These methods attempt to synthesize various pseudo-fake faces to cover known forgery as much as possible. By training on these augmented samples, the detectors can learn the common forgery features. In this scenario, the manipulation operations of new forgeries should be known as a prior, in order to synthesize the applicable pseudo-fake faces. However, the technical details of new forgeries may not be accessible in reality, limiting the application of these existing methods. In our scenario, we do not require the technical details of new forgeries. Instead, we can collect a set of videos that contains new forgery faces, and simply extract all faces in a video without knowing the label (real or fake) of faces. Using these samples, we can align the detectors to learn the transferable knowledge from the known forgery to this new forgery.\nThis scenario is practical and useful. For example, we can obtain video sets by searching the keywords, e.g., DeepFake, on video platforms. The obtained videos are likely a mix of real and fake faces due to the natural deviation of search engines, i.e., we cannot ensure whether a video that appeared in search results is real or fake. Even though the search results are perfectly matched, i.e., the video-level annotation is correct, the obtained faces can still be mixed, as a video usually contains multiple faces and we cannot know which face is real or fake if only video-level annotation is given. Under this practical circumstance, our method can expose new forgeries with these unlabeled samples."

However, such one-direction adaptation methods are insufficient in digging out the subtle forgery knowledge from unlabeled target data.

We then create a new feature extractor  with the parameters , which has the same model structure as  and whose parameters  are initialized with the same parameters as .  is combined with the classifier  to make up the student model. It can be seen that the teacher and student models use the same model structure.\nConcretely, the self-distillation loss  is defined as\nHere  and  are the distillation probabilities of the teacher model and student model, respectively. In particular,\nwhere  is the class index and  is a scalar temperature parameter.  is obtained by replacing  with  in (5  ###reference_###).\nThe Eq.(4) is designed to distill the knowledge from the teacher model learned in the target domain into the student model. By using self-distillation, the student model can enhance the features of the teacher model, thus capturing more effective knowledge regarding the target domain in comparison to the teacher model. We then utilize  as described in the forward adaptation stage on the same discriminator  and the distilled feature extractor . The overall loss of this stage is the combination of these two loss terms as\nwhere  and  are weight factors. We optimize this loss adversarially as in the forward adaptation stage. At the end of each training epoch, we update the teacher model by copying the parameters of the student model to the teacher model:\nThis backward adaptation strategy provides more accurate guidance from the teacher model, thus promoting the student model to learn more knowledge. Both the self-distillation loss  and adversarial loss  do not need any class labels from both domains."

We design a ViT-based network as our feature extractor  due to its strong power on vision tasks. Specifically, our feature extractor has two branches, a visual branch and a frequency branch. For the visual branch, we split the face image into  patches. These patches are flattened and linear transformed to patch embeddings, which are then equipped with position embeddings as the tokens for a ViT [29  ###reference_b29###] architecture to extract visual features. The ViT in this branch contains  transformer layers, each of which is composed by a multi-headed self-attention (MSA) layer and a MLP layer [57  ###reference_b57###]. For the frequency branch, we first convert the face image from RGB color space to YCbCr color space and then apply DCT transformation to each component with a  block [10  ###reference_b10###]. The transformed frequency maps are concatenated together and sent into a convolution block. We then flatten the feature maps from the convolution block into  vectors, which are used as the input to another ViT architecture for frequency feature extraction. This ViT architecture contains  transformer layers. The visual features and frequency features are concatenated together as the forgery features for DeepFake detection. The classifier  has a simple structure with only two linear layers, which takes the forgery features as input and outputs the logit of prediction. It is worth emphasizing that our method is independent of the network architecture, and can be integrated into other mainstream architectures.

It includes  original videos from YouTube, covering a wide range of subjects and scenarios, and consists of four different manipulation techniques: Deepfakes (DF), Face2Face (F2F), FaceSwap (FS), and NeuralTextures (NT), each representing a distinct form of facial manipulation. All these videos have three compression versions, raw, high quality (HQ) and low quality (LQ). From these original videos,  videos,  videos and  videos are used for training, validating and testing, respectively. For each manipulation technique, we employ the same partition as the original videos for training, validating, and testing. We focus on the frame-level deepfake detection and perform evaluation on both HQ and LQ data. As our approach does not rely on extra augmentation operations, we only crop faces from each frame during the preprocessing stage. Concretely, we randomly extract 8 frames for each video clip and crop out the face with 1.3\u00d7 of the detection box obtained by RetinaFace [59  ###reference_b59###].\nCeleb-DF was proposed more recently, which provides a diverse set of challenges, such as pose, lighting conditions, facial expressions and camera quality, commonly encountered in real-world scenarios. It also offers different levels of manipulation difficulty, ranging from subtle and realistic manipulations to more obvious and noticeable ones. This dataset contains  original videos and  DeepFake videos. We respectively use  and  videos for training and testing. To construct the training data, we randomly extract  frames from real videos and  frames from fake videos for data balance. As for the testing set, we extract  frames from real and fake videos. The face is cropped out using the same way as for FF++.\nStyleGAN [58  ###reference_b58###] trains a generative adversairal network on Flickr-Faces-HQ dataset (FFHQ), which consists of  real face images, to synthesize high-quality fake faces. The synthesizing process focuses on human faces and offers various high-quality synthetic faces by disentangling style and content information in latent space to control the process of face generation. We randomly select  original images from FFHQ and  synthetic images from the generated dataset, where  original images and  synthetic images are for training and the remaining images are for testing.\nDFDCP [71  ###reference_b71###] is a preview dataset for deepfakes detection challenge consisting of  videos with two facial modification algorithms, considering diversity in several axes (gender, skin-tone, age, etc.).\nFFIW-10K [67  ###reference_b67###] is a large-scale dataset, which comprises  pristine videos and  high-quality forgery videos for training. Another  real videos and  manipulated videos are also provided for testing. Different from the aforementioned datasets, this dataset contains multiple forgery faces in a single video."

Cross-manipulation-datasets represents the adaptation from one dataset to another different one. Cross-manipulation-types is to adapt one type of forgery to a different type. This scenario is more challenging, as different types have significant discrepancies in the manipulation methods, datasets and forged areas, e.g., faceswap faces to GAN-synthesized faces.\nTo make a fair comparison with the previous works [16  ###reference_b16###, 35  ###reference_b35###], each domain adaptation scenario is trained on the training set and tested on the testing set.

The results reveal that our method performs favourably on both source and target domains, achieving the AUC metric  on most of the source and target adaptation pairs.\nThis demonstrates the effectiveness of our method. We also observe that the performance with NT  FS is limited on the source.

Note that TALL-Swin has no reports corresponding to this scenario. Thus we reproduce its results following its default settings. This method is trained using all videos in FF++.\nWe would like to clarify that the experiment configurations between our method and these other methods are different, as these methods tackle this task under different scenarios. Specifically, these data-level methods first obtain and empirically analyze the new forgery videos, and then summarize a common forgery knowledge as a prior, e.g., the blending boundary and frequency clues. By contrast, the prior knowledge for us is the collected videos without labels. Even though the experiment configurations are not the same, the results can also reflect the effectiveness of our method in exposing new forgeries.\nTable II  ###reference_### compares the performance of our method with those of the existing methods under the O2O scenario on both HQ and LQ levels, where the results of our method are marked by gray colour. For the existing methods, we use the score of each method reported in its original paper. As SBI [18  ###reference_b18###] was only evaluated on raw quality images, we retrain it using the code provided in [18  ###reference_b18###] on HQ and LQ for a fair comparison.\nFor the HQ level, it can be seen from the top part of Table II  ###reference_### that our method outperforms the augmentation-based methods, Face X-ray and SBI, by a large margin. Since these two methods require prior knowledge of manipulation, they can hardly handle the forgery that has notable differences from the prior knowledge. The frequency-based method SRM performs well on several cases, notably, FS  F2F and NT  F2F. But its performances are highly degraded in many more cases compared to our method. For example, in DF  FS, our method is nearly 100% better than SRM, and in FS  DF, our method is 44% better than SRM, while in DF  F2F, our method is 30% better than SRM, and in F2F  DF, our method is 20% better than SRM. Similar observations can be drawn by comparing our method with SOLA-sup. Based on the available data from [64  ###reference_b64###], the performance of our method are slightly better than those of FTCN. When compared to TALL-Swin, we observe our method achieves better generalization performances than TALL-Swin. It can also be seen that our method significantly outperforms LTW, Xception, FOT, DDT and FEAT. Moreover, in the more challenging LQ level, our method significantly outperforms all the five benchmarks, as can be seen from the bottom part of Table II  ###reference_###.\n###figure_13### Fig. 5  ###reference_### shows the t-SNE [65  ###reference_b65###] visualizations of feature distribution for two O2O cross-manipulations (FS  F2F, FS  NT) without and with adaptation using our method on both source and target domain. For the target domain, it can be seen that the features of real and fake faces separate well using our method, in contrast to the mixed features without our method (see (a,b) and (c,d)). For the source domain, we can observe that their feature distributions are still discriminative (see (e,f) and (g,h)). Fig. 6  ###reference_### shows several examples of Grad-CAM [56  ###reference_b56###] (the left six columns), which reveals that our method catches more discriminative features on face regions for both real and fake faces."

Specifically, we retrain their models on FF++ HQ and LQ scenarios by using their published codes. The experimental results are summarized in Table III  ###reference_###, which demonstrate that our method outperforms these three domain adaptation methods in recognizing faces with unseen forgeries. SSRT [53  ###reference_b53###] is a counterpart method that also employs a powerful vision transformer as the backbone network. It can be seen that SSRT occasionally fails to transfer knowledge in some scenarios, e.g., DFNT and FSF2F, while our bi-directional network achieves more stable and superior performance than SSRT almost in all adaptation tasks. DANN and MDD respectively represent an adversarial-based method and a discrepancy-based method. We observe that DANN achieves more generalized performance than MDD but our approach surpasses both DANN and MDD by a large margin. The reason mainly lies in that the proposed bi-directional adaptation strategy enables the model to fully grab the common forgery features across domains. Overall, the results suggest that our approach effectively encourages the detector to learn common forgery features, leading to improved generalization ability."

The results are presented in Table V  ###reference_###. We observe that our method achieves better performance than others on the DFDCP dataset, mainly because our method can learn common forgery features among different manipulated methods. However, SBI surpasses our method on the FFIW dataset. This is because this dataset contains many side faces, while the faces in FF++ dataset are usually frontal. This discrepancy largely increases the domain gap, which may disturb our model in learning common forgery features. Since SBI is designed to create a variety of faces for data augmentation, which likely includes such distorted faces in training, resulting in better performance than us."

Different from the recent methods, which empirically seeks the common traces on data view, our method aims to transfer the forgery knowledge from known forgeries (fully labeled source domain) to new forgeries (label-free target domain). Since the general domain adaptation methods are not competent to capture the forgery features, we have designed a new bi-directional adaptation strategy that considers both the forward adaptation and backward adaptation. Specifically, the forward adaptation transfers the knowledge from the source to the target domain, and the backward adaptation reverses the adaptation from the target to the source domain. With this backward adaptation, the detector can be further enhanced to learn new forgery features from unlabeled data and avoid forgetting the known knowledge of known forgery. Extensive experiments have been conducted on three datasets with the comparison to several existing state-of-the-art counterparts. The results obtained have demonstrated that our method is effective in exposing new forgeries, and it can be integrated into various architectures to improve their generalization ability."

+            "text": "Reinforcement learning (RL) Sutton & Barto (2018  ###reference_b53###) has recently become a highly active research area of machine learning that learns to make sequential decisions via interacting with the environment. In recent years, RL has achieved tremendous success so far in many applications such as control, job scheduling, online advertising, and game-playing Zhang & Dietterich (1995  ###reference_b72###); Pednault et al. (2002  ###reference_b40###); Mnih et al. (2013  ###reference_b37###), to mention a few. One of the central tasks of RL is to solve a certain (expected) reward optimization problem for decision-making. Following the research theme, we consider the following problem of maximizing the regularized expected reward:\nwhere  is a closed proper convex (possibly nonsmooth) function, ,  is the reward function depending on the parameter , and  denotes the probability distribution over a given subset  parameterized by . By adapting the convention in RL, we call  a policy parameterized by . Moreover, for the rest of this paper, we denote  as the expected reward function in the non-oblivious setting. The learning objective is to learn a decision rule via finding the policy parameter  that maximizes the regularized expected reward. To the best of our knowledge, the study on the general model (1  ###reference_###) has been limited in the literature. Hence, developing and analyzing algorithmic frameworks for solving the problem is of great interest.\nThere are large body of works in supervised learning focusing on the oblivious setting Zhang (2004  ###reference_b71###); Hastie et al. (2009  ###reference_b19###); Shapiro et al. (2021  ###reference_b50###), i.e., , where  is sampled from an invariant distribution . Clearly, problem (1  ###reference_###) can be viewed as a generalization of those machine learning problems with oblivious objective functions. In the literature, an RL problem is often formulated as a discrete-time and discounted Markov decision processes (MDPs) Sutton & Barto (2018  ###reference_b53###) which aims to learn an optimal policy via optimizing the (discounted) cumulative sum of rewards. We can also see that the learning objective of an MDP can be covered by the problem (1  ###reference_###) with the property that the function  does not depend on  (see Example 3.3  ###reference_theorem3###). Recently, the application of RL for solving combinatorial optimization (CO) problems which are typically NP-hard has attracted much attention. These CO problems may include the traveling salesman problem and related problems Bello et al. (2016  ###reference_b8###); Mazyavkina et al. (2021  ###reference_b33###), the reward optimization problem arising from the finite expression method Liang & Yang (2022  ###reference_b30###); Song et al. (2023  ###reference_b52###), and the general binary optimization problem Chen et al. (2023  ###reference_b11###), to name just a few. The common key component of the aforementioned applications is the reward optimization, which could also be formulated as problem (1  ###reference_###). There also exist problems with general reward functions that are outside the scope of cumulative sum of rewards of trajectories that are used in MDPs. An interesting example is the MDP with general utilities; see, e.g., Zhang et al. (2020a  ###reference_b67###); Kumar et al. (2022  ###reference_b25###); Barakat et al. (2023  ###reference_b5###) and references therein.\nAdding a regularizer to the objective function is a commonly used technique to impose desirable structures to the solution and/or to greatly enhance the expression power and applicability of RL Lan (2023  ###reference_b27###); Zhan et al. (2023  ###reference_b66###). When one considers the direct/simplex parameterization Agarwal et al. (2021  ###reference_b2###) of , a regularization function using the indicator function for the standard probability simplex is needed. Moreover, by using other indicator functions for general convex sets, one is able to impose some additional constraints on the parameter . For the softmax parameterization, one may also enforce a bounded constraint to  to prevent it taking values that are too large. This can avoid potential numerical issues, including the overflow error on a floating point system. On the other hand, there are incomplete parametric policy classes, such as the log-linear and neural policy classes, that are often formulated as , where  is a closed convex set Agarwal et al. (2021  ###reference_b2###). In this case, the indicator function is still necessary and useful. Some recent works (see, e.g., Ahmed et al. (2019  ###reference_b3###); Agarwal et al. (2020  ###reference_b1###); Mei et al. (2020  ###reference_b34###); Cen et al. (2022  ###reference_b10###)) have investigated the impact of the entropy regularization for MDPs. Systematic studies on general convex regularization for MDPs have been limited until the recent works Pham et al. (2020  ###reference_b42###); Lan (2023  ###reference_b27###); Zhan et al. (2023  ###reference_b66###). Finally, problem (1  ###reference_###) takes the same form as the stochastic optimization problem with decision-dependent distributions (see e.g., Drusvyatskiy & Xiao (2023  ###reference_b13###) and references therein), leading to numerous real-world applications such as performative prediction Mendler-D\u00fcnner et al. (2020  ###reference_b35###); Perdomo et al. (2020  ###reference_b41###), concept drift Gama et al. (2014  ###reference_b16###), strategic classification Tsirtsis et al. (2024  ###reference_b56###); Milli et al. (2019  ###reference_b36###), and casual inference Yao et al. (2021  ###reference_b63###). Consequently, we can see that problem (1  ###reference_###) is in fact quite general and has promising modeling power, as it covers many existing problems in the literature.\nThe purpose of this paper is to leverage existing tools and results in MDPs and nonconvex optimization for solving the general regularized expected reward optimization problem (1  ###reference_###) with general policy parameterization, which, to the best of our knowledge, has not been formally considered in the RL literature. It is well known that the policy gradient method Williams (1992  ###reference_b57###); Sutton et al. (1999  ###reference_b54###); Baxter & Bartlett (2001  ###reference_b6###), which lies in the heart of RL, is one of the most competitive and efficient algorithms due to its simplicity and versatility. Moreover, the policy gradient method is readily implemented and can be paired with other effective techniques. In this paper, we observe that the stochastic proximal gradient method, which shares the same spirit of the policy gradient method, can be applied directly for solving the targeted problem (1  ###reference_###) with convergence guarantees to a stationary point. Since the classical stochastic gradient estimator typically introduces a large variance, there is also a need to consider designing advanced stochastic gradient estimators with smaller variances. To this end, we shall also look into a certain stochastic variance-reduced proximal gradient method and analyze its convergence properties. In particular, the contributions of this paper are summarized as follows.\nWe consider a novel and general regularized reward optimization model (1  ###reference_###) that covers many existing important models in the machine learning and optimization literature. Thus, problem (1  ###reference_###) admits a promising modeling power which encourages potential applications.\nIn order to solve our targeted problem, we consider applying the classical stochastic proximal gradient method and analyze its convergence properties. We first demonstrate that the gradient of  is Lipschitz continuous under standard conditions with respect to the reward function  and the parameterized policy . Using the L-smoothness of , we then show that the classical stochastic proximal gradient method with a constant step-size (depending only on the Lipschitz constant for ) for solving problem (1  ###reference_###) outputs an -stationary point (see Definition 3.4  ###reference_theorem4###) within  iterations, and the sample size for each iteration is , where  is a given tolerance. Thus, the total sample complexity becomes , which matches the current state-of-the-art sample complexity of the classical stochastic policy gradient for MDPs; see e.g., Williams (1992  ###reference_b57###); Baxter & Bartlett (2001  ###reference_b6###); Zhang et al. (2020b  ###reference_b70###); Xiong et al. (2021  ###reference_b59###); Yuan et al. (2022  ###reference_b65###).\nMoreover, in order to further reduce the variance of the stochastic gradient estimator, we utilize an importance sampling based probabilistic gradient estimator which leads to an efficient single-looped variance reduced method. The application of this probabilistic gradient estimator is motivated by the recent progress in developing efficient stochastic variance-reduced gradient methods for solving stochastic optimization Li et al. (2021b  ###reference_b29###) and (unregularized) MDPs Gargiani et al. (2022  ###reference_b17###). We show that, under additional technical conditions, the total sample complexity is improved from  to . This result again matches the results of some existing competitive variance-reduced methods for MDPs Papini et al. (2018  ###reference_b39###); Xu et al. (2019  ###reference_b60###); Pham et al. (2020  ###reference_b42###); Huang et al. (2021  ###reference_b20###); Yang et al. (2022  ###reference_b62###); Gargiani et al. (2022  ###reference_b17###). Moreover, to the best of our knowledge, the application of the above probabilistic gradient estimator is new for solving the regularized expected reward optimization (1  ###reference_###).\nThe rest of this paper is organized as follows. We first summarize some relative works in Section 2  ###reference_###. Next, in Section 3  ###reference_###, we present some background information that are needed for the exposition of this paper. Then, in Section 4  ###reference_###, we describe the classical stochastic proximal gradient method for solving (1  ###reference_###) and present the convergence properties of this method under standard technical conditions. Section 5  ###reference_### is dedicated to describing and analyzing the stochastic variance-reduced proximal gradient method with an importance sampling based probabilistic gradient estimator. Finally, we make some concluding remarks, and list certain limitations and future research directions of this paper in Section 6  ###reference_###."

One of the most influential algorithms for solving RL problems is the policy gradient method, built upon the foundations established in Williams (1992  ###reference_b57###); Sutton et al. (1999  ###reference_b54###); Baxter & Bartlett (2001  ###reference_b6###). Motivated by the empirical success of the policy gradient method and its variants, analyzing the convergence properties for these methods has long been one of the most active research topics in RL. Since the objective function  is generally nonconcave, early works Sutton et al. (1999  ###reference_b54###); Pirotta et al. (2015  ###reference_b43###) focused on the asymptotic convergence properties to a stationary point. By utilizing the special structure in (entropy regularized) MDPs, recent works Liu et al. (2019  ###reference_b31###); Mei et al. (2020  ###reference_b34###); Agarwal et al. (2021  ###reference_b2###); Li et al. (2021a  ###reference_b28###); Xiao (2022  ###reference_b58###); Cen et al. (2022  ###reference_b10###); Lan (2023  ###reference_b27###); Fatkhullin et al. (2023  ###reference_b15###) provided some exciting results on the global convergence. Meanwhile, since the exact gradient of the objective function can hardly be computed, sampling-based approximated/stochastic gradients have gained much attention. Therefore, many works investigated the convergence properties, including the iteration and sample complexities, for these algorithms with inexact gradients; see e.g., Zhang et al. (2020b  ###reference_b70###); Liu et al. (2020  ###reference_b32###); Zhang et al. (2021b  ###reference_b69###); Xiong et al. (2021  ###reference_b59###); Yuan et al. (2022  ###reference_b65###); Lan (2023  ###reference_b27###) and references therein.\nVariance reduction. While the classical stochastic gradient estimator is straightforward and simple to implement, one of its most critical issues is that the variance of the inexact gradient estimator can be large, which generally slows down the convergence of the algorithm. To alleviate this issue, an attractive approach is to pair the sample-based policy gradient methods with certain variance-reduced techniques. Variance-reduced methods were originally developed for solving (oblivious) stochastic optimization problems Johnson & Zhang (2013  ###reference_b22###); Nguyen et al. (2017  ###reference_b38###); Fang et al. (2018  ###reference_b14###); Li et al. (2021b  ###reference_b29###) typically arising from supervised learning tasks. Motivated by the superior theoretical properties and practical performance of the stochastic variance-reduced gradient methods, similar algorithmic frameworks have recently been applied for solving MDPs Papini et al. (2018  ###reference_b39###); Xu et al. (2019  ###reference_b60###); Yuan et al. (2020  ###reference_b64###); Pham et al. (2020  ###reference_b42###); Huang et al. (2021  ###reference_b20###); Yang et al. (2022  ###reference_b62###); Gargiani et al. (2022  ###reference_b17###).\nStochastic optimization with decision-dependent distributions. Stochastic optimization is the core of modern machine learning applications, whose main objective is to learn a decision rule from a limited data sample that is assumed to generalize well to the entire population Drusvyatskiy & Xiao (2023  ###reference_b13###). In the classical supervised learning framework Zhang (2004  ###reference_b71###); Hastie et al. (2009  ###reference_b19###); Shapiro et al. (2021  ###reference_b50###), the underlying data distribution is assumed to be static, which turns out to be a crucial assumption when analyzing the convergence properties of the common stochastic optimization algorithms. On the other hand, there are problems where the distribution changes over the course of iterations of a specific algorithm, and these are closely related to the concept of performative prediction Perdomo et al. (2020  ###reference_b41###). In this case, understanding the convergence properties of the algorithm becomes more challenging. Toward this, some recent progress has been made on (strongly) convex stochastic optimization with decision-dependent distributions Mendler-D\u00fcnner et al. (2020  ###reference_b35###); Perdomo et al. (2020  ###reference_b41###); Drusvyatskiy & Xiao (2023  ###reference_b13###). Moreover, other works have also considered nonconvex problems and obtained some promising results; see Dong et al. (2023  ###reference_b12###); Jagadeesan et al. (2022  ###reference_b21###) and references therein. Developing theoretical foundation for these problems has become a very active field nowadays.\nRL with general utilities. It is known that the goal of an agent associated with an MDP is to seek an optimal policy via maximizing the cumulative discounted reward Sutton & Barto (2018  ###reference_b53###). However, there are decision problems of interest having more general forms. Beyond the scope of the expected cumulative reward in MDPs, some recent works also looked into RL problems with general utilities; see e.g., Zhang et al. (2020a  ###reference_b67###); Kumar et al. (2022  ###reference_b25###); Barakat et al. (2023  ###reference_b5###) as mentioned previously. Global convergence results can also be derived via investigating the hidden convex structure Zhang et al. (2020a  ###reference_b67###) inherited from the MDP."

The fundamental idea of the algorithm is to replace the true gradient , which are not available for most of the time, with a stochastic gradient estimator in the classical proximal gradient method Beck (2017  ###reference_b7###). The method can be viewed as extensions to the projected policy gradient method with direct parameterization Agarwal et al. (2021  ###reference_b2###) and the stochastic policy gradient method for unregularized MDPs Williams (1992  ###reference_b57###). The detailed description of the algorithm is presented in Algorithm 1  ###reference_###.\nFor notational simplicity, we denote\nFrom Algorithm 1  ###reference_###, we see that at each iteration,  data points, namely , are sample according to the current probability distribution . Using these data points, we can construct a REINFORCE-type stochastic gradient estimator . Then, the algorithm just performs a proximal gradient ascent updating. Let  be the maximal number of iterations, then a sequence  can be generated, and the output solution is selected randomly from this sequence. Next, we shall proceed to answer the questions that how to choose the learning rate , how large the sample size  should be, and how many iterations for the algorithm to output an -stationary point for a given , theoretically. The next lemma establishes the L-smoothness of  whose proof is given at Appendix A.1  ###reference_###.\nUnder Assumptions 3.1  ###reference_theorem1### and 3.2  ###reference_theorem2###, the gradient of  is -smooth, i.e.,\nwith .\nFor an MDP with finite action space and state space as in Example 3.3  ###reference_theorem3###, the Lipschitz constant of  can be expressed in terms of ,  and .

From this theorem, if one sets , i.e., , then there is no randomness along the iterations and the convergence property is reduced to\nwhich is implied by classical results on proximal gradient method (see e.g., Beck (2017  ###reference_b7###)). However, since the exact full gradient  is rarely computable, it is common to require the variance (i.e., the trace of the covariance matrix) of the stochastic estimator to be bounded. The latter condition plays an essential role in analyzing stochastic first-order methods for solving nonconvex optimization problems, including RL applications; see, e.g., Beck (2017  ###reference_b7###); Papini et al. (2018  ###reference_b39###); Shen et al. (2019  ###reference_b51###); Lan (2020  ###reference_b26###); Yang et al.

To the best of our knowledge, to get the same convergence properties as Theorem 4.5  ###reference_theorem5### under the same conditions for problem (1  ###reference_###), the large batch-size is required.\nAs mentioned in introduction, some recent progress has been made for analyzing the global convergence properties of the policy gradient methods for MDPs, which greatly rely on the concepts of gradient domination and its extensions Agarwal et al.

This concept is also highly related to the classical P\u0141-condition Polyak (1963  ###reference_b44###) and K\u0141-condition Bolte et al. (2007  ###reference_b9###) in the field of optimization. One of the key ideas is to assume or verify that the difference between the optimal objective function value, namely , and  can be bounded by the quantity depending on the norm of the gradient mapping at an arbitrary point. In particular, suppose that there exists a positive constant  such that\nwhere  is defined in Remark 3.5  ###reference_theorem5### (see e.g., Xiao (2022  ###reference_b58###)).

+            "text": "Recall from Theorem 4.3  ###reference_theorem3### that, there is a trade-off between the sample complexity and the iteration complexity of Algorithm 1  ###reference_###. In particular, while there is little room for us to improve the term  which corresponds to the iteration complexity, it is possible to construct  in an advanced manner to improve the sample complexity. Therefore, our main goal in this section is to reduce the expected sample complexity while keeping the term  small. We achieve this goal by considering the stochastic variance-reduced gradient methods that have recently attracted much attention. Among these variance-reduced methods, as argued in Gargiani et al. (2022  ###reference_b17###), the ProbAbilistic Gradient Estimator (PAGE) proposed in Li et al. (2021b  ###reference_b29###) has a simple structure, and can lead to optimal convergence properties. These appealing features make it attractive in machine learning applications. Therefore, in this section, we also consider the stochastic variance-reduced proximal gradient method with PAGE for solving the problem (1  ###reference_###).\nPAGE is originally designed for the stochastic nonconvex minimization in the oblivious setting:\nwhere  is a fixed probability distribution and  is a certain differentiable (and possibly nonconvex) loss function. For stochastic gradient-type methods, a certain stochastic gradient estimator for  is required for performing the optimization. At the -th iteration, given a probability  and the current gradient estimator , PAGE proposed to replace the vanilla mini-batch gradient estimator with the following unbiased stochastic estimator:\nwhere  are sampled from ,  denote the sample sizes. Some key advantages of applying PAGE are summarized as follows. First, the algorithm is single-looped, which admit simpler implementation compared with existing double-looped variance reduced methods. Second, the probability  can be adjusted dynamically, leading to more flexibilities. Third, one can choose  to be much smaller than  to guarantee the same iteration complexity as the vanilla SGD. Thus, the overall sample complexity can be significantly reduced. However, the application of PAGE to our setting needs significant modifications and extensions, which we shall demonstrate below. To the best of our knowledge, the application of PAGE for solving the general regularized reward optimization problem in the non-oblivious setting considered in this paper is new.\nFor notational simplicity, for the rest of this section, we denote\nfor , where  denotes the importance weight between  and . Note also that\nThe description of the proposed PAGE variance-reduced stochastic proximal gradient method is given in Algorithm 2  ###reference_###.\nIt is clear that the only difference between Algorithm 1  ###reference_### and Algorithm 2  ###reference_### is the choice of the gradient estimator. At each iteration of the latter algorithm, we have two choices for the gradient estimator, where, with probability , one chooses the same estimator as in Algorithm 1  ###reference_### with a sample size , and with probability , one constructs the estimator in a clever way which combines the information of the current iterate and the previous one. Since the data set  is sampled according to the current probability distribution , we need to rely on the importance weight between  and  and construct the gradient estimator , which is an unbiased estimator for , so that  becomes an unbiased estimator of . Indeed, one can easily verify that for any , it holds that\ni.e.,  is an unbiased estimator for \nprovided that .\nNext, we shall analyze the convergence properties of Algorithm 2  ###reference_###. Our analysis relies on the following assumption on the importance weight, which essentially controls the change of the distributions.\nLet , the importance weight between  and  is well-defined and there exists a constant  such that\nClearly, the significance of the constant  (if exists) may depend sensitively on  and . To see this, let us assume that for any ,  is a discrete distribution over a set of finite points  for which  for all . Now, suppose that  with . Then, a simple calculation shows that\nHowever, it is possible that there exists a certain  or tiny. In this case,  can be huge or even infinity. Fortunately, the regularization term  can help to avoid such undesired situations via imposing the lower-bounded constraints  for all . In this case, we see that .\nNote that Assumption 5.1  ###reference_theorem1### is also employed in many existing works Papini et al. (2018  ###reference_b39###); Xu et al. (2019  ###reference_b60###); Pham et al. (2020  ###reference_b42###); Yuan et al. (2020  ###reference_b64###); Gargiani et al. (2022  ###reference_b17###). However, this assumption could be too strong, and it is not checkable in general. Addressing the relaxation of this assumption through the development of a more sophisticated algorithmic framework is beyond the scope of this paper. Here, we would like to mention some recent progress on relaxing this stringent condition for MDPs. By constructing additional stochastic estimators for the Hessian matrix of the objective function, Shen et al. (2019  ###reference_b51###) proposed a Hessian-aided policy-gradient-type method that improves the sample complexity from  to  without assuming Assumption 5.1  ###reference_theorem1###. Later, by explicitly controlling changes in the parameter , Zhang et al. (2021a  ###reference_b68###) developed a truncated stochastic incremental variance-reduced policy gradient method to prevent the variance of the importance weights from becoming excessively large leading to the  sample complexity. By utilizing general Bregman divergences, Yuan et al. (2022  ###reference_b65###) proposed a double-looped variance-reduced mirror policy optimization approach and established an  sample complexity, without requiring Hessian information or Assumption 5.1  ###reference_theorem1###. Recently, following the research theme as Shen et al. (2019  ###reference_b51###), Salehkaleybar et al. (2022  ###reference_b47###) also incorporated second-order information into the stochastic gradient estimator. By using momentum, the variance-reduced algorithm proposed in Salehkaleybar et al. (2022  ###reference_b47###) has some appealing features, including the small batch-size and parameter-free implementation. Recently, by imposing additional conditions, including the Lipschitz continuity of the Hessian of the score function  and the Fisher-non-degeneracy condition of the policy, Fatkhullin et al. (2023  ###reference_b15###) derived improved (global) convergence guarantees for solving MDPs. We think that the above ideas can also be explored for solving the general model (1  ###reference_###).\nThe bounded variance of the importance weight implies that the (expected) distance between  and  is controlled by the distance between  and , for any given . In particular, we have the following lemma, whose proof is provided in Appendix A.5  ###reference_###.\nUnder Assumption 3.1  ###reference_theorem1###, Assumption 3.2  ###reference_theorem2### and Assumption 5.1  ###reference_theorem1###, then it holds that\nwhere  is a constant defined as\nUnder the considered assumptions, we are able to provide an estimate for the term\n, which plays an essential role in deriving an improved sample complexity of Algorithm 2  ###reference_###.

Let  and  be the sequences generated by Algorithm 2  ###reference_###, then it holds that\nWe are now ready to present the main result on the convergence property of the Algorithm 2  ###reference_### by showing how to select the sample sizes  and , probability , and the learning rate . Intuitively,  is typically a large number and one does not want to perform samplings with  samples frequently, thus the probability  and the sample size  should both be small.

Our results are summarized in the following theorem.

For a given , we set  with  and .\nChoose a learning rate  satisfying . Then, running Algorithm 2  ###reference_### for  iterations outputs a point  satisfying\nMoreover, the total expected sample complexity is .\nBy using the stochastic variance-reduce gradient estimator with PAGE and the importance sampling technique, we have improved the total sample complexity from  to , under the considered conditions. This result matches with the current competitive results established in Xu et al. (2019  ###reference_b60###); Yuan et al. (2020  ###reference_b64###); Pham et al. (2020  ###reference_b42###); Gargiani et al. (2022  ###reference_b17###) for solving MDPs and is applicable to the general model (1  ###reference_###). Finally, as mentioned in Remark 4.7  ###reference_theorem7###, by assuming or verifying stronger conditions, such as the gradient domination and its extensions, it is also possible to derive some global convergence results. Again, such a possibility is left to a future research direction."

We have established the  sample complexity of the classical stochastic proximal gradient method and the  sample complexity of the stochastic variance-reduced proximal gradient method with an importance sampling based probabilistic gradient estimator. Our results match the sample complexity of their most competitive counterparts under similar settings for Markov decision processes.\nMeanwhile, we have also suspected some limitations in the current paper. First, due to the nonconcavity of the objective function, we found it challenging to derive global convergence properties of the stochastic proximal gradient method and its variants without imposing additional conditions. On the other hand, analyzing the sample complexity for achieving convergence to second-order stationary points\u2014thereby avoiding saddle points\u2014may be more realistic and feasible Arjevani et al.

How to relax this condition for our general model deserves further investigation. Last but not least, since we focus more on the theoretical analysis in this paper and due to the space constraint, we did not conduct any numerical simulation to examine the practical efficiency of the proposed methods. We shall try to delve into these challenges and get better understandings of the proposed problem and algorithms in a future research.\nFinally, this paper has demonstrated the possibility of pairing the stochastic proximal gradient method with efficient variance reduction techniques Li et al.

+    "abstract": "A robust and efficient optimization-based 2D/3D registration framework is crucial for the navigation system of orthopedic surgical robots. It can provide precise position information of surgical instruments and implants during surgery.\nWhile artificial intelligence technology has advanced rapidly in recent years, traditional optimization-based registration methods remain indispensable in the field of 2D/3D registration.\nThe exceptional precision of this method enables it to be considered as a post-processing step of the learning-based methods, thereby offering a reliable assurance for registration.\nIn this paper, we present a coarse-to-fine registration framework based on the CMA-ES algorithm.\nWe conducted intensive testing of our method using data from different parts of the spine. The results shows the effectiveness of the proposed framework on real orthopedic spine surgery clinical data.\nThis work can be viewed as an additional extension that complements the optimization-based methods employed in our previous studies.",

The challenges in automatic X-ray to CT registration arise due to differences in image acquisition protocols, patient positioning, and image artifacts. Additionally, anatomical deformations caused by patient movement or pathological changes present further complexities.\nAnd it has shown promising results in various clinical applications, including orthopedics, interventional radiology and minimally invasive surgical robot navigation. It allows clinicians to effectively fuse the information from X-ray and CT modalities, providing a comprehensive understanding of a patient\u2019s condition and facilitating more precise and targeted medical interventions [15  ###reference_b15###].\nRecent progress in machine learning has had a significant impact on 2D/3D registration, revolutionizing the field and improving the accuracy and efficiency of the registration process [3  ###reference_b3###].\nResearchers have started exploring the use of neural networks as a substitute for traditional similarity measures [13  ###reference_b13###], treating registration as a Markov decision process [12  ###reference_b12###], and employing differentiable projection operators to directly implement an end-to-end registration framework [4  ###reference_b4###, 7  ###reference_b7###].\nSome existing works [6  ###reference_b6###, 17  ###reference_b17###] get rid of the problem of lack of real data by adopting self-supervised training strategies.\nHowever, in the existing literature, Most learning-based registration methods still require the use of optimization-based methods as a post-processing step to fine-tune the results. For example, [1  ###reference_b1###, 4  ###reference_b4###] use neural networks to obtain an approximately convex mapping, which can increase the capture range of registration. But this network similarity function is overly smooth, thereby leading to premature convergence when the pose closely approximates the ground truth. In order to ensure the accuracy of registration, a benchmark based on covariance adaptive evolution strategy (CMA-ES) [9  ###reference_b9###] is adopted for refinement.\nGao et al. [5  ###reference_b5###], Gopalakrishnan et al. [7  ###reference_b7###] and Zhang et al. [17  ###reference_b17###] all proposed differentiable renderer and employed the gradient descent optimization method to refine the pose using this module.\nThis implies that an efficient and robust optimization-based registration method is still beneficial to the existing registration framework.\nIn this work, we proposed a coarse-to-fine benchmark for 2D/3D registration. The framework uses CMA-ES as the optimizer and is divided into two resolutions for pose estimation.\nWe validate our proposed framework on vertebral data, demonstrating its ability to achieve high registration accuracy.\nOur paper is organized as follows: Sect. 2  ###reference_### provides an overview of related work, Sect. 3  ###reference_### describes the proposed method. And in Sect. 4  ###reference_###, we present our experimental setup, datasets, quantitative and qualitative results, and analysis.\nThis work can be seen as a supplementary note on the optimization-based methods we used in [1  ###reference_b1###, 2  ###reference_b2###]."

Common mathematical optimization methods for 2D/3D registration include Powell-Brent [14  ###reference_b14###], Nelder-Mead, nonlinear conjugate gradient, gradient descent, evolutionary strategy, etc [16  ###reference_b16###].\nIt is widely recognized that intensity-based methods [8  ###reference_b8###] can achieve high registration accuracy. However, these methods also have two significant drawbacks: long computation time and limited capture range. In recent years, many literatures have tried to use neural networks as pose initialization for intensity-based methods [4  ###reference_b4###, 6  ###reference_b6###, 17  ###reference_b17###]. Learning-based methods can often initialize poses near the ground truth, which makes up for the shortcomings of the smaller capture range of intensity-based methods."

One potential drawback of feature-based methods is that they heavily rely on accurate detection of geometric features, which in itself can be a challenging task.\nErrors from the feature detection step are inevitably propagated into the registration result, making feature-based methods in general less accurate. Errors from the feature detection step inevitably propagate into the registration result, generally compromising the accuracy of feature-based methods."

In the coarse registration stage, we use multi-scale normalized cross-correlation (mNCC) as the similarity function, while the fine registration method uses gradient correlation (GC).\nIn the following part of this section, we will first introduce the problem formulation of this task and make a brief introduction on the adopted optimizer, CMA-ES. We will also discuss the similarity functions we used for the proposed framework."

It is a probabilistic-based optimization method that simulates natural selection and genetic mechanisms of biological evolution to optimize parameters.\nThe core idea of CMA-ES is to search for the optimal solution by gradually adjusting the probability distribution of the parameters. In each generation, CMA-ES generates a set of candidate solutions based on the current probability distribution and updates the distribution according to their performance. By iteratively optimizing the probability distribution, CMA-ES can effectively explore the search space and find better solutions.\nCMA-ES performs well in handling high-dimensional, non-convex optimization problems and exhibits robustness and convergence properties compared to other optimization algorithms. A public\nimplementation of CMA-ES can be found here1\u2020\u20201https://github.com/CyberAgentAILab/cmaes\nIn our framework, if the current similarity function is below a predefined threshold, the registration is considered to have converged. We also set up an additional early stopping strategy. If the minimum value of the similarity loss hasn\u2019t been updated after 100 generations of sampling, the registration process will be terminated immediately."

The initial mTRE is , , and  at the 95th, 75th, and 50th percentiles respectively. Because the sizes of different anatomical parts of the spine are different, the mTRE obtained from the experimental results on cervical, thoracic and lumbar spine data varies greatly. It will be more intuitive to directly compare the errors of each component in rotation and translation. It is worth noting that although the mean values of errors in some directions of rotation and translation became larger after registration in our experiments, this was actually affected by outliers.\nTaking the total errors in the three directions of rotation (rx, ry, rz) as an example: their initial errors are ,  and , while the errors after registration are ,  and .\nAnd the medians of the initial errors are 3.10, 2.90, and 3.16, while the medians of the registration results are noticeably smaller, measuring 0.52, 1.32, and 0.24 respectively.\n###table_1### The performance of our framework on lumbar and thoracic spine data is very convincing, which hints at the feasibility of this framework in clinical application. But we also noticed its unsatisfactory performance in cervical spine data.\nWe believe that this is mainly due to two reasons: 1)The cervical spine area contains a greater number of joints and bone structures, and has a wider range of motion compared to other spinal regions. As a result, cervical spine images may exhibit a more intricate shape and structure, and the registration process must consider a broader range of variations and uncertainties.\nIn contrast, the lumbar and thoracic regions are comparatively larger and have relatively simple structures, so the registration process may be easier.\n2)The patient\u2019s head direction was not entirely consistent during preoperative and intraoperative imaging, leading to deformations in certain parts of the cervical spine that exceeded the 6 DoF rigid body transformation limit.\nWe can mitigate the impact of jaws with significant shape differences in the image by partitioning the region of interest.\nHowever, in such cases, adopting regularization of rigid bodies for cervical spine registration may result in a higher likelihood of falling into local minima."

We verified the effectiveness of this framework using paired CT and X-ray images from three different anatomical sites (lumbar, thoracic, and cervical vertebrae) in the context of spinal surgical navigation.\nOur experimental results have yielded highly competitive outcomes. We aim for this method to serve as a benchmark, coupled with learning-based registration methods, and to potentially be implemented in clinical surgical settings in the future."

+    "abstract": "Despite the many advances of Large Language Models (LLMs) and their unprecedented rapid evolution, their impact and integration into every facet of our daily lives is limited due to various reasons. One critical factor hindering their widespread adoption is the occurrence of hallucinations, where LLMs invent answers that sound realistic, yet drift away from factual truth.\nIn this paper, we present a novel method for detecting hallucinations in large language models, which tackles a critical issue in the adoption of these models in various real-world scenarios.\nThrough extensive evaluations across multiple datasets and LLMs, including Llama-2, we study the hallucination levels of various recent LLMs and demonstrate the effectiveness of our method to automatically detect them. Notably, we observe up to 87% hallucinations for Llama-2 in a specific experiment, where our method achieves a Balanced Accuracy of 81%, all without relying on external knowledge\n111Our code, datasets, and task prompts can be found here. .",

+            "text": "Human studies have shown that people tend to be inconsistent when they are not telling the truth Brewer et al. (1999  ###reference_b3###). As such, a common interrogation technique consists of repeated interviews that attempt to challenge the interviewer\u2019s consistency in order to assess its credibility Granhag and Str\u00f6mwall (2001  ###reference_b10###). Truth tellers\u2019 answers are well-grounded in their memory, hence, inconsistencies in the respondent\u2019s answers are a strong indication of her not telling the truth Brewer et al. (1999  ###reference_b3###); Dianiska and Meissner (2023  ###reference_b8###). Inspired by these studies, we present a novel method for hallucination detection in LLMs. Our approach, which we call\nInterrogateLLM,\nemploys a systematic evaluation of model-generated responses for potential hallucinations by repeating the process of reconstructing a query from its generated answer.\nRepeated interviews are a very common and effective verification technique for human interrogations, however, it is not foolproof. In some cases, respondents manage to provide repeated false states that are consistent, while in other cases, truth-tellers may provide inconsistent responses due to memory errors Bartlett (1995  ###reference_b2###).\nIn a similar fashion, our method is not flawless; it represents an additional step towards addressing the yet unsolved problem of hallucination detection.\nNevertheless, similar to the use of consistency tests in humans, commonly employed for their effectiveness, our method also demonstrates high efficacy.\nIn recent years, the emergence of LLMs such as GPT-3 Brown et al. (2020  ###reference_b4###), PaLM Chowdhery et al. (2022  ###reference_b6###), and LLama Touvron et al. (2023a  ###reference_b21###, b  ###reference_b22###) has revolutionized natural language processing. These models enable machines to understand and generate human-like text with unprecedented fluency and coherence.\nTrained on vast amounts of text data, they have demonstrated remarkable capabilities in various applications, from automated content generation to virtual assistants, and beyond. However, their remarkable performance comes with a set of challenges and concerns that need to be addressed for their responsible and effective use.\nA major concern is the phenomenon of hallucination, whereby these language models generate misleading, potentially harmful, or erroneous text. Hallucination can be characterized by the presence of false information in the output generated by the language model that lacks a factual basis. There are significant challenges associated with the deployment of large language models in real-world applications, especially in those involving critical information or decision-making processes.\nDetecting and minimizing hallucinations in LLMs is crucial for ensuring their trustworthiness and reliability, especially in contexts where these models play a pivotal role in communication and decision-making. Existing methods for evaluating model-generated text often rely on surface-level metrics such as fluency and coherence, which may not effectively capture the underlying issue of hallucinations. Therefore, there is a pressing need for a systematic and effective method to detect and mitigate hallucinations in the outputs of these models. Despite its significance, addressing this challenge remains an open issue Ji et al. (2023  ###reference_b11###).\nOur method, InterrogateLLM, operates on the premise that language models exhibiting hallucinations produce inconsistent and incorrect responses to subsequent queries based on the hallucinated information.\nTo identify hallucination in a generated answer, our approach involves prompting the model multiple times to reconstruct the input query using the generated answer. Subsequently, InterrogateLLM quantifies the inconsistency level between the original query and the reconstructed queries.\nBy leveraging the observed inconsistencies, our approach effectively identifies potential instances of hallucination.\nWhen a large-language model generates a hallucination, it struggles to consistently reconstruct the original query, leading to variations in responses. This interrogation strategy serves as the cornerstone of our approach for detecting hallucinations in generated answers.\nThe contributions of our paper are outlined as follows: (1) introduction of the InterrogateLLM method designed for detecting hallucinations in textual answers generated by LLMs. (2) we propose an innovative evaluation approach specifically tailored to the task of hallucination detection, leveraging three datasets associated with our proposed text generation tasks. (3) we investigate the hallucination levels exhibited by recent LLMs, including Llama2, shedding light on their fidelity levels. (4) we present comprehensive performance reports on InterrogateLLM and its variants, conducting a thorough comparison with alternative methods through extensive evaluations.\n###figure_1###"

This is well-documented in a recent comprehensive survey conducted by Ji et al. (2023  ###reference_b11###), which provides an insightful overview of hallucinations in diverse natural language generation contexts.\nIn Liu et al. (2022  ###reference_b15###), the authors presented a token-level reference-free hallucination detection task along with an additional dataset designed for hallucination detection in free-form text. This dataset consists of textual passages with perturbations, and the objective is to determine whether the entire passage exhibits hallucinations. It is crucial to emphasize that our task differs from their setup, as we specifically address hallucination detection within few-shot prompts involving query-answer sequences.\nTo address inconsistencies in generated text, SelfCheckGPT, introduced by Manakul et al. (2023b  ###reference_b17###), leverages multiple stochastic samples generated by LLMs using the same query. SelfCheckGPT evaluates the coherence between the response and the stochastic samples by querying the same LLM multiple times. Specifically, it incorporates an additional prompt that includes a stochastic sample and a sentence from the generated text and predicts whether the sentence is supported by the stochastic sample.\nThe approach validates each sentence by conditioning the LLM on each stochastic sample.\nThe methodology of SelfCheckGPT encompasses various approaches, including one based on BERTScore Fu et al. (2023  ###reference_b9###), and another employing a multiple-choice question answering and generation approach (MQAG) Manakul et al. (2023a  ###reference_b16###), as well as n-gram and LLM-Prompting.\nOur method is benchmarked against this baseline, using the last approach in our study.\nIn recent research, Azaria and Mitchell (2023  ###reference_b1###) proposed a method employing a multilayer perceptron classifier that uses hidden representations from language models to predict sentence truthfulness. However, this approach necessitates labeled data for supervised training and access to the internal states of the language model, which may not always be readily available.\nIn Kadavath et al. (2022  ###reference_b12###), the authors present a self-evaluation technique where models are trained to predict their knowledge of the answer to any given free-form question. This approach entails prompting the language model to internally assess the accuracy of its previous predictions, including estimating the likelihood that its generated response or answer is correct. It is worth noting that this method requires labeled data for model training, making it a supervised task, which differs from our settings."

In other words, in this process, we map the generated answer to the source domain, by querying one or more LLMs, each trying to reconstruct the original query .\nBy denoting the set of reconstructed queries as , this \u201cbackward\u201d process can be expressed as:\nNote that the size of  depends on the number of LLMs used in .\nThe motivation for employing a backward process is to reconstruct the original query  based on the generated answer .

Therefore,\nTo determine if  suffers from hallucination, a language embedding model is utilized to assess the similarity between the set of reconstructed queries  and the original query . Both the generated queries and the original query are transformed into vectors within the same embedding space. For a given embedding model , which generates -dimensional vectors from the input text, the embedding vector for the original query  is denoted as .

A higher temperature (e.g., 1.0) makes the output more creative and diverse, while a lower temperature (e.g., 0.2) makes the output more focused and deterministic. Specifically, the temperature is applied through a softmax function that transforms a vector into a probability distribution.\nIn text generation, the softmax function is applied to the model\u2019s logit vector, which corresponds to the supported tokens in the vocabulary.\nThe softmax operation can be written as follows:\nWhere  is the probability of selecting the -th token in the vocabulary,  is the logit vector,  is the temperature parameter and  is the number of tokens in the vocabulary. When  is high (low), the exponential function  is less (more) sensitive to small differences in the logit values, making the probabilities more diverse (focused).\nAs complementary experimental explorations, we examine the influence of temperature values on InterrogateLLM during the backward process, which is iterated  times. By introducing dynamic temperature adjustments, our goal is to study the method\u2019s accuracy when employed with a range of backward processes exhibiting diverse creativity levels. To this end, we set the temperature for each backward process as follows:\nwhere  represents the temperature for the -th backward pass (), and  is the model default temperature (see Sec. 5.2  ###reference_### for more details).\nThis temperature scheduling allows for facilitating a controlled ascent in temperatures across the multiple backward processes, promoting enhanced exploration in the space of reconstructed queries.\nThe details and results of this additional study are reported in the experiments, Sec. 5.6  ###reference_###."

Specifically, in this study, we evaluate InterrogateLLM with  taking values in the range  (higher  values can be considered at the expense of more compute power).\nThe tables reveal that utilizing  in the backward step is crucial in all three experiments. Notably, the best results are consistently obtained with higher  value, where  takes the lead in the majority of cases. Therefore, we hypothesize that increasing the value of  could potentially enhance the results, albeit at the expense of additional computational resources.\nIn addition, we observe that the ensemble of all three models (GPT-3, Llama-2 (7B), and Llama-2 (13B)) yielded the highest performance across all  values. This suggests once again that combining recovery scores from multiple models enhances hallucination detection.\nFig. 2  ###reference_### depicts the enhancements arising from the different values of , shown for each dataset separately, and reported with both AUC and B-ACC metrics.\nEach data point represents the average result across all three forward LLMs along with all their corresponding backward LLMs (i.e. the average of each column in tables 3  ###reference_###,9  ###reference_### and 10  ###reference_###). As can be seen, the data reveals a consistent trend wherein the cumulative improvements exhibit a proportional relationship with the size of .\nWe extend our investigation to varying temperatures for the backward process.\nFor each index , the InterrogateLLM method utilizes a variable temperature  as defined in Eq.(8  ###reference_###).\nThis temperature adjustment aimed to augment the creativity and stochastic aspects of the backward model  throughout the query reconstruction process, fostering the generation of a more diverse set of reconstructed queries.\nTab. 4  ###reference_###, and Tab. 6  ###reference_###, 7  ###reference_### from the supplementary Sec.A.3  ###reference_###, present the results of InterrogateLLM with , when using the same temperature through all the backward processes versus using variable temperatures, as proposed in InterrogateLLM. As can be seen, the variable temperature improves the results across most experiments in the Movies datasets, while yielding on-par performance in the Books and GCI datasets (see Tab.6  ###reference_###, 7  ###reference_###).\nWe hypothesize that the introduction of variable temperature, generating reconstructions with diverse levels of creativity, can be particularly helpful in mitigating instances of mode \"collapse\", in which certain backward models consistently generate identical reconstructions. In such cases, the incorporation of variable temperature becomes more important. The proposed method utilizes a diverse range of reconstructions. When the vast majority of these diverse reconstructions closely align with the original query, it signifies robust backward processes, better reflecting a non-hallucinated answer and consequently leading to improved accuracy scores.\nMore ablative experiments related to the choices made in Eq. 5  ###reference_### can be found in the sup.

The backward process can reconstruct a diverse set of query candidates, deviating from the original query.\n(2) Hallucinating Back and Forth:\nInstances were observed where a single backward process by the same LLM model, which hallucinated an answer, could reconstruct the same query. This severe hallucination indicates a symmetric mapping between a query and a hallucinated answer, implying hallucinations in both directions. We observed a mitigation of this issue when employing an ensemble of models.\n(3) Detecting Hallucinations in Semi-Truth Answers:\nIdentifying hallucinations in semi-truth answers proves more challenging. In some cases, the model only hallucinated a small portion of the answer (e.g., generating an entire cast of a movie with one additional actor not part of the movie). InterrogateLLM was able to recover the original movie, failing to detect the low-severity hallucination within the answer."

To ascertain the closeness of the generated query to the original, we employ two strategies: the maximum (Max) and the average (Average) of the K cosine similarity scores. Notably, in the majority of cases, the average outperformed the maximum, indicating a more robust measure for query similarity. We attribute this observation to the sensitivity of the maximum strategy to noisy cosine similarity scores, which tend to be prevalent in certain instances. Our analysis suggests that the average is a more reliable indicator of query similarity, providing a stable and effective metric for the evaluation of our reconstruction approach.\nFull results with avg/max are presented in tables 5  ###reference_###, 6  ###reference_###, 7  ###reference_###, 8  ###reference_###, 9  ###reference_### and 10  ###reference_###.\nTab. 8  ###reference_###, 9  ###reference_### and 10  ###reference_###. depicts the performance of InterrogateLLM on the books and GCI datasets, with variable  values.

+    "abstract": "Transfer learning has become an essential part of medical imaging classification algorithms, often leveraging ImageNet weights. The domain shift from natural to medical images has prompted alternatives such as RadImageNet, often showing comparable classification performance. However, it remains unclear whether the performance gains from transfer learning stem from improved generalization or shortcut learning. To address this, we conceptualize confounders by introducing the Medical Imaging Contextualized Confounder Taxonomy (MICCAT) and investigate a range of confounders across it \u2013 whether synthetic or sampled from the data \u2013 using two public chest X-ray and CT datasets. We show that ImageNet and RadImageNet achieve comparable classification performance, yet ImageNet is much more prone to overfitting to confounders. We recommend that researchers using ImageNet-pretrained models reexamine their model robustness by conducting similar experiments.

However, their deployment in real-world clinical settings is hindered by various challenges, with one of the most critical being their hidden reliance on spurious features [27  ###reference_b27###]. Recent research has highlighted the detrimental effects of this reliance, including bias against demographic subgroups [2  ###reference_b2###], limited generalization across hospitals [28  ###reference_b28###], and the risk of clinical errors that may harm patients [21  ###reference_b21###].\nDespite transfer learning becoming a cornerstone in medical imaging, its impact on model generalization remains largely unexplored. Pre-training on ImageNet has become a standard practice due to its success in 2D image classification. While some studies have explored alternative medical source datasets for pre-training [3  ###reference_b3###, 19  ###reference_b19###, 29  ###reference_b29###, 16  ###reference_b16###], ImageNet continues to serve as a strong baseline.\nRecent literature suggests that the size of the source dataset may matter more than its domain or composition [22  ###reference_b22###, 9  ###reference_b9###]. However, [15  ###reference_b15###] demonstrated performance improvements through source dataset pruning. In this context, we argue that cross-domain transfer can be problematic, especially when source dataset selection is solely based on classification performance, as it may inadvertently lead to shortcut learning rather than genuine improvements in generalization. Shortcut learning can be considered antithetical to generalization and robustness as it is not a failure to generalize per se, but rather a failure to generalize in the intended direction [10  ###reference_b10###].\nIn this paper, we investigate how the domain of the source dataset affects model generalization. First, we conceptualize confounding factors in medical images by introducing the Medical Imaging Contextualized Confounder Taxonomy (MICCAT) and generate synthetic or sample real-world confounders from MICCAT, commonly found in chest X-rays and CT scans, to systematically assess model robustness. Second, we compare models pre-trained on natural (ImageNet) and medical (RadImageNet) datasets across X-ray and CT tasks and show substantial differences in robustness to shortcut learning despite comparable predictive performance. While transfer learning has been observed to enhance model robustness [13  ###reference_b13###], our results suggest that it may not hold true when transferring across domains, cautioning against using ImageNet pre-trained models in medical contexts due to their susceptibility to shortcut learning. Furthermore, our findings highlight the limitations of conventional performance metrics based on i.i.d. datasets, which fail to discern between genuine improvements in generalization and shortcut learning. Thus, we advocate for a more nuanced evaluation of transfer learning effectiveness to ensure the reliability and safety of machine learning applications in clinical settings."

+            "text": "To the best of our knowledge, there is no standardized taxonomy for classifying potential confounders in medical images. Thus, to better structure our robustness analysis, we propose a new taxonomy: Medical Imaging Contextualized Confounder Taxonomy (MICCAT).\nPrevious work has shown that standard demographic attributes such as sex, age, or ethnicity may act as confounders, leading to shortcut learning and potentially disadvantaging historically underserved subgroups [2  ###reference_b2###]. However, solely focusing on standard protected demographic attributes may overlook other specific factors related to clusters of patients for which the systems tend to fail [8  ###reference_b8###]. In MICCAT, we identify these as \u2018contextualized confounders\u2019, as they are often domain or context-specific, associated with particular image modalities, organs, hospitalization conditions, or diseases.\nFirst, MICCAT differentiates between patient level and environment level confounders. At the patient level, we make a distinction between standard demographic attributes (e.g., sex, age, race) and contextualized anatomical confounders, which arise from inherent anatomical properties of the organs and human body or disease variations in images. This distinction is crucial as standard demographic attributes often serve as proxies for underlying causes of learned shortcuts. For instance, ethnicity may proxy skin color in dermatoscopic images. Identifying the true shortcut cause allows for more targeted interventions to mitigate biases. We define the concept of environment level confounders, which stem from contextualized external or imaging confounders. The former include physical or virtual elements in images due to external factors like hospitalization devices or image tags, while the latter include characteristics related to the imaging modality itself, such as noise, motion blur, or differences in intensities due to equipment or acquisition parameters. Fig. 1  ###reference_### illustrates this taxonomy with examples for each category.\nConfounders studied in this paper. We explore the MICCAT by investigating four examples of confounders, highlighted by a black outline in Fig. 1  ###reference_###:\nAn external confounder (a tag) placed in the upper left corner of the image, representing confounding features introduced by various imaging devices across or within hospitals (Fig. 2(a)  ###reference_sf1###).\nTwo typical imaging confounders: denoising (Fig. 2(c)  ###reference_sf3###), widely used by various vendors to reduce noise for enhanced readability [11  ###reference_b11###], and Poisson noise (Fig. 2(d)  ###reference_sf4###), originating from quantum statistics of photons, which cannot be mitigated through hardware engineering, unlike noise introduced by circuit-related artifacts [26  ###reference_b26###].\nA patient-level confounder where we use patient gender, which is easily accessible in metadata, as a proxy for a broader spectrum of anatomical confounders. We use the same term for this variable as in the original dataset."

NIH CXR14 is used to represent cross-domain transfer for both ImageNet and RadImageNet, as X-ray is not included in RadImageNet, while LIDC-IDRI serves as an in-domain example for RadImageNet and a cross-domain example for ImageNet.\n###figure_2### ###figure_3### ###figure_4### ###figure_5### Confounder generation.\nPatient gender is sampled to correlate \u2018Female\u2019 with the label.\nA tag is placed further away from the edges (starting at px in the original image of px), to ensure it remains intact during training despite augmentations applied (Fig. 2(a)  ###reference_sf1###).\nThe simplest method for Denoising is applying low-pass filtering which entails converting the input image from the spatial to the frequency domain using Discrete Fourier Transform (DFT), followed by element-wise multiplication with the low-pass filter  to generate the filtered image:\nwhere  represents the distance from the origin in the frequency domain, and  is the specified cutoff frequency. In our experiments, we set px. Subsequently, the high-frequency suppressed image is reconstructed in the spatial domain via the Inverse Discrete Fourier Transform (IDFT), resulting in a smoothing effect (see Fig. 2(c)  ###reference_sf3###).\nPoisson noise originating from quantum statistics of photons is formulated as a Poisson random process:\nwhere  represents Poisson noise, which notably affects image quality under low-dose conditions (e.g., low-dose CT and X-ray screenings), while the linear recording  is obtained via the reversed conversion from attenuation  given the prior information of the source intensity , where  is the pixel values of projections, obtained from the image space as described in [17  ###reference_b17###].\nTo simulate low-dose screening, we add Poisson noise to the image (Fig. 2(d)  ###reference_sf4###) by adjusting the  parameter to control noise levels. We aim for minimal noise, setting  after visually examining the noise to ensure it remains imperceptible.\nEvaluation.\nTo investigate shortcut learning systematically, we construct development datasets for fine-tuning, focusing on a binary classification task. We introduce previously mentioned confounders (e.g., \u2018Female\u2019) into the positive class with a controlled probability  to deliberately influence the learning process, replicating scenarios where real-world data may contain confounders. To assess the presence of shortcut learning, we evaluate the fine-tuned models with independently and identically distributed (i.i.d.) as well as out-of-distribution (o.o.d.) test sets. In the o.o.d. set, we introduce the same artifact used during fine-tuning to the negative class with , such that the models are tested on instances where artifacts appear in the opposite class compared to what they encountered during training. We evaluate the fine-tuned models using the AUC (area under the receiver operating characteristic curve).\n# images in\n% split\n% class split\nImage\nBatch\n\nTask\nConfounder\ntest/dev(trainval)\ntrain/val\npos/neg\nsize\nsize\n\nLung mass (NIH CXR14 [25  ###reference_b25###])\nT, D, N\n83/248\n90/10\n30/70\n512  512\n32\n\nLung mass (LIDC-IDRI [1  ###reference_b1###])\nT, D, N\n1710/500\n80/20\n50/50\n362  362\n32\n\nAtelectasis (NIH CXR14 [25  ###reference_b25###])\nGender\n400/400\n85/15\n50/50\n256  256\n64\nMedical targets. We create separate binary classification tasks for lung mass detection using subsets of images sourced from two datasets: the chest X-ray NIH CXR14 [25  ###reference_b25###] subset annotated by clinicians [20  ###reference_b20###], and the chest CT dataset LIDC-IDRI [1  ###reference_b1###] annotated by four radiologists. From the latter, we sample paired positive and negative 2D slices from the original 3D scans using nodule ROI annotations, representing any kind of lesions and their nearby slices without remarkable findings. We include synthetic artifacts (a tag, denoising, and Poisson noise) in both tasks. For the case where patient gender serves as the confounding feature, we sample posterior to anterior (PA) images from NIH CXR14 to construct a binary classification task for atelectasis. We deliberately limit the size of our development datasets, encompassing both balanced and unbalanced class distributions to cover a spectrum of clinical scenarios. Data splits for training, validation, and testing preserve class distribution and are stratified by patient. Further details are available in Table 1  ###reference_###.\nFine-tuning details.\nWe use ResNet50 [12  ###reference_b12###], InceptionV3 [24  ###reference_b24###], InceptionResNetV2 [23  ###reference_b23###], and DenseNet121 [14  ###reference_b14###] as the backbones with average pooling and a dropout layer (0.5 probability). The models are trained using cross-entropy loss with Adam optimizer (learning rate: ) for a maximum of 200 epochs with early stopping after 30 epochs of no improvement in validation loss (AUC for the balanced tasks). This configuration, established during early tuning, proved flexible enough to accommodate different initializations and target datasets. During training, we apply image augmentations including random rotation (up to 10 degrees), width and height shifts, shear, and zoom, all set to 0.1, with a fill mode set to \u2018nearest\u2019. Models were implemented using Keras [4  ###reference_b4###] library and fine-tuned on an NVIDIA Tesla A100 GPU card."

Fig. 3  ###reference_### shows that ImageNet and RadImageNet achieve comparable AUC on i.i.d. test set, however, when subjected to o.o.d. test set, notable differences emerge. Specifically, ImageNet\u2019s o.o.d. performance on X-rays, confounded by tag, denoising, and patient gender, drops more compared to RadImageNet, indicating ImageNet\u2019s higher reliance on spurious correlations. This could be because certain features, for instance, a tag (letters), may serve as a discriminative feature in ImageNet, e.g., for the computer keyboard class. However, RadImageNet is invariant to such features as they are not consistently associated with specific labels across different classes, and this invariance transfers to the target task. We observed similar trends in the CT dataset, with the o.o.d. AUC decreasing from 0.84 to 0.02 for ImageNet, and to 0.22 for RadImageNet (for tag); and from 0.7 to 0.01 for ImageNet, and from 0.83 only to 0.6 for RadImageNet (for denoising). It is worth noting that RadImageNet models tend to train longer, averaging 141 epochs across all experiments, compared to 72 epochs for ImageNet models.\n###figure_7### Although tag and denoising are designed to replicate real-world artifacts, they lack the diversity found in real-world scenarios. Patient gender presents a more realistic confounder. Here, the performance gap between ImageNet and RadImageNet is smaller (by 0.12 on average for ) yet remains statistically significant (permutation test, , for ). This suggests that RadImageNet\u2019s resilience to shortcuts extends to more realistic confounder variations, further emphasizing its robustness in medical image classification. Here we only provide results for ResNet50,\nhowever, we observed similar results for InceptionV3, InceptionRes-NetV2, and DenseNet121.\nRandom initialization appears robust to shortcut learning, with consistent o.o.d. performance as  increases. However, this is mainly due to the unbalanced class distribution in the lung mass prediction task within the NIH CXR14 dataset, where randomly initialized models tend to predict the overrepresented negative class (). Conversely, in the case of a balanced class distribution in the CT target dataset, the o.o.d. performance of randomly initialized models deteriorates to a similar degree as that of ImageNet-initialized models.\nShortcuts come in all shapes and sizes. ImageNet and RadImageNet both heavily rely on Poisson noise in X-rays (Fig. 4  ###reference_###, upper left) but RadImageNet shows greater robustness to noise in CT scans compared to ImageNet (Fig. 4  ###reference_###, lower left). It is important to note that Poisson noise manifests differently in X-rays and CT scans. In X-rays, Poisson noise introduces graininess characterized by random and pixel-wise independent variations, while in CT scans, it appears as streak artifacts structurally correlated to projections and thus is not pixel-wise independent in the image domain.\nTo understand the impact of this difference, we directly introduce Poisson noise  in the image domain for CT scans, mimicking the pixel-wise independence seen in X-rays. However, since CT scans inherently contain noise, this introduces a confounding feature of high versus low levels of noise, as opposed to the original confounder of noise versus no noise.\nTo simulate a corresponding scenario in X-rays, we generate two levels of Poisson noise:  for the positives and  for the negatives (reversed for the o.o.d. test set). Both models show a smaller drop in o.o.d. AUC across modalities, indicating a reduced reliance on the noise shortcut (Fig. 4  ###reference_###, right). This suggests that discerning between high and low noise levels is a more challenging task than simply detecting the presence of noise.\nRadImageNet maintains its robustness in CT scans, while in X-rays, RadImageNet relies on noise to a similar extent as ImageNet. This may be explained by the absence of X-ray images in RadImageNet, leading to a lack of robust X-ray representations that would resist pixel-wise independent noise \u2013 a phenomenon less common in CT, MR, and ultrasound, modalities included in RadImageNet. This highlights that even transferring from a medical source of a different modality may lead to overfitting on confounders.\nWhile our findings generalize over the four tested CNNs, we did not investigate other architectures, such as transformers, due to CNNs competitive performance [7  ###reference_b7###]. Although we expect that our observations might hold true for transformers, given their tendency to reuse features to an even greater extent than CNNs [18  ###reference_b18###], we defer experimental verification to future research.\nIn our exploration of the MICCAT, we found that RadImageNet models are generally more robust to shortcuts. However, there is some variability within the category of imaging confounders, and the importance of the source domain in anatomical confounders seems to be lower. Expanding the scope to include other confounders would offer a more comprehensive understanding of the taxonomy landscape and provide insights into the nuances within each category, facilitating better-informed source dataset selection and evaluation strategies. MICCAT paves the way for a more systematic approach to addressing shortcut learning in medical imaging in general by providing a framework for thorough confounder curation and enabling a comprehensive analysis."

+    "abstract": "Learning to defer (L2D) aims to improve human-AI collaboration systems by learning how to defer decisions to humans when they are more likely to be correct than an ML classifier. Existing research in L2D overlooks key real-world aspects that impede its practical adoption, namely: i) neglecting cost-sensitive scenarios, where type I and type II errors have different costs; ii) requiring concurrent human predictions for every instance of the training dataset; and iii) not dealing with human work-capacity constraints. To address these issues, we propose the deferral under cost and capacity constraints framework (DeCCaF). DeCCaF is a novel L2D approach, employing supervised learning to model the probability of human error under less restrictive data requirements (only one expert prediction per instance) and using constraint programming to globally minimize the error cost, subject to workload limitations. We test DeCCaF in a series of cost-sensitive fraud detection scenarios with different teams of 9 synthetic fraud analysts, with individual work-capacity constraints. The results demonstrate that our approach performs significantly better than the baselines in a wide array of scenarios, achieving an average  reduction in the misclassification cost. The code used for the experiments is available at https://github.com/feedzai/deccaf",

+            "text": "An increasing body of recent research has been dedicated to human-AI collaboration (HAIC), with several authors arguing that humans have complementary sets of strengths and weaknesses to those of AI (De-Arteaga et al., 2020  ###reference_b12###; Dellermann et al., 2019  ###reference_b13###). Collaborative systems have demonstrated that humans are able to rectify model predictions in specific instances (De-Arteaga et al., 2020  ###reference_b12###), and have shown that humans collaborating with an ML model may achieve synergistic performance: a higher performance than humans or models alone (Inkpen et al., 2022  ###reference_b26###). In high-stakes scenarios where ML models can outperform humans, such as healthcare (Gulshan et al., 2016  ###reference_b19###), HAIC systems can help address safety concerns (e.g., the effect of changes in the data distribution (Gama et al., 2014  ###reference_b15###)), by ensuring the involvement of humans in the decision-making process.\nThe state-of-the-art framework to manage assignments in HAIC is learning to defer (L2D)\n(Charusaie et al., 2022  ###reference_b8###; Hemmer et al., 2022  ###reference_b22###; Raghu et al., 2019b  ###reference_b44###; a  ###reference_b43###; Mozannar & Sontag, 2020b  ###reference_b39###; Mozannar et al., 2023  ###reference_b40###; Madras et al., 2018b  ###reference_b35###; Steege, 2023  ###reference_b48###; Verma & Nalisnick, 2022a  ###reference_b50###; Verma et al., 2023  ###reference_b52###). L2D aims to improve upon previous approaches, such as rejection learning (Chow, 1970  ###reference_b9###; Cortes et al., 2016  ###reference_b10###), which defer based solely on the ML model\u2019s confidence, by also estimating the human confidence in a given prediction and passing the instance to the decision-maker who is most likely to make the correct decision.\nPrevious work in L2D does not address several key aspects of collaborative systems. In real-world scenarios, multiple human experts are employed to carry out the classification task, as the volume of instances to process cannot be handled by a single human. However, only a small subset of L2D research focuses on the multi-expert setting, where decisions have to be distributed throughout a team comprised of a single ML classifier and multiple human experts (Keswani et al., 2021  ###reference_b31###; Hemmer et al., 2022  ###reference_b22###; Verma et al., 2023  ###reference_b52###). To the best of our knowledge, Verma et al. (2023  ###reference_b52###) propose the only two consistent multi-expert L2D formulations, with both approaches assuming the existence of every expert\u2019s predictions for all training instances. In real-world applications, we often have more limited data availability, with only a single expert (De-Arteaga et al., 2020  ###reference_b12###) or a small subset of the experts (Gulshan et al., 2016  ###reference_b19###) providing predictions for each instance. This means that a practitioner aiming to train L2D algorithms would have to purposefully collect the set of every expert\u2019s predictions for a sample of instances, which could incur large costs or even be unfeasible. We will propose L2D architectures that allow for assigners to be trained assuming that each instance is accompanied by the prediction of only one expert out of the team.\nCurrent multi-expert L2D methods also neglect human capacity limitations. Should there be an expert that consistently outperforms the model and all the other experts, the optimal assignment would be to defer all cases to that expert, which in practice is not feasible. Furthermore, current work neglects cost-sensitive scenarios, where the cost of misclassification can be class or even instance-dependent (e.g., in medicine, false alarms are generally considered less harmful than failing to diagnose a disease).\n###figure_1### To address the aforementioned L2D limitations, we propose the deferral under cost and capacity constraints framework (DeCCaF): a novel deferral approach to manage assignments in cost-sensitive human-AI decision-making, which respects human capacity constraints. Our method is comprised of three separate components, represented schematically in Figure 1  ###reference_###: (1) an ML classifier modelling the probability of the target class given the instance features; (2) a human expertise model (HEM) that models the probabilities of correctness of each of the experts in the team; and (3) an assigner that computes the best possible set of assignments given misclassification costs and capacity constraints.\nDue to the lack of sizeable datasets with multiple human predictions and to the high costs associated with producing one, we empirically validate DeCCaF in a series of realistic cost-sensitive fraud detection scenarios, where a team of 9 synthetic fraud analysts and one ML classifier are tasked with reviewing financial fraud alerts. We conclude that, across all scenarios, DeCCaF performs similarly to, or significantly better than L2D baselines, as measured by average misclassification costs.\nIn summary, our contributions are:\nDeCCaF: a novel L2D method that models human behavior under limited data availability, using constraint programming to obtain the optimal set of assignments (Section 3  ###reference_###).\nA novel benchmark of complex, feature-dependent synthetic expert decisions, in a realistic financial fraud detection scenario (Section 4.1  ###reference_###).\nExperimental evidence that our approach outperforms baselines in a set of realistic, cost-sensitive fraud detection scenarios (Section 5  ###reference_###).\nIn Section 2  ###reference_###, we describe the relevant related work, focusing on recent developments in multi-expert L2D and examining the shortcomings of the deferral systems proposed so far. We also discuss current practices in L2D evaluation, particularly the use of synthetically generated expert predictions, and how they can be improved.\nWe then describe DeCCaF in Section 3  ###reference_###, first by formulating a novel training method, compatible with limited data availability, for the commonly used classifier-rejector framework (Mozannar & Sontag, 2020a  ###reference_b38###; Verma & Nalisnick, 2022a  ###reference_b50###; Verma et al., 2023  ###reference_b52###; Cortes et al., 2016  ###reference_b10###), demonstrating that it produces optimal unconstrained deferral.\nAs the traditional classifier-rejector approach fails to consider the existence of human work-capacity limitations, we propose a novel formulation for global assignment optimization under capacity constraints. In Section 4  ###reference_### we detail a realistic fraud detection experimental setup as well as the method for the synthetic expert prediction generation. We also discuss the capacity-aware baselines used in our L2D benchmark. The experimental results are reported and analyzed in Section 5  ###reference_###."

+            "text": "The simplest deferral approach in the literature is rejection learning (ReL), which dates back to the work of Chow (1970  ###reference_b9###); Cortes et al. (2016  ###reference_b10###).\nIn a HAIC setting, ReL defers to humans the instances that the model rejects to predict (Madras et al., 2018b  ###reference_b35###; Raghu et al., 2019a  ###reference_b43###).\nA simple example (Hendrycks & Gimpel, 2017  ###reference_b24###) is to obtain uncertainty estimates of the model prediction for each instance, rejecting to predict if the uncertainty estimate is above a given threshold.\nMadras et al. (2018b  ###reference_b35###) criticize ReL, arguing that it does not consider the performance of the human involved in the task and propose learning to defer (L2D), where the classifier and assignment system are jointly trained, taking into account a single model and a single human and accounting for human error in the training loss. Many authors have since contributed to the single-expert framework: Mozannar & Sontag (2020b  ###reference_b39###) show that the loss proposed by Madras et al. (2018b  ###reference_b35###) is inconsistent, proposing a consistent surrogate loss that yields better results in testing; Verma & Nalisnick (2022b  ###reference_b51###) critique the approach of Mozannar & Sontag (2020b  ###reference_b39###), demonstrating that their surrogate loss has a degenerate parameterization, causing miscalibration of the estimated probability of expert correctness.\nKeswani et al. (2021  ###reference_b31###) observe that decisions can often be deferred to one or more humans out of a team, expanding L2D to the multi-expert setting. Verma et al. (2023  ###reference_b52###) propose the first consistent and calibrated surrogate losses for the multi-expert setting, by adapting the work of Verma & Nalisnick (2022b  ###reference_b51###) and the softmax surrogate loss of Mozannar & Sontag (2020b  ###reference_b39###). All aforementioned studies focus on deriving surrogates for the  loss, meaning they are not directly applicable to cost-sensitive scenarios, where the cost of erring can be class-dependent (i.e., different costs for false positive and false negative errors), or even instance-specific (i.e., every instance has an associated misclassification cost).\nAnother key facet of L2D research is the interplay between the two components of an assignment system: the rejector (which decides whether to defer and to whom) and the classifier (which produces automatic predictions if the rejector chooses not to defer). Mozannar & Sontag (2020b  ###reference_b39###) argue that the main classifier should specialize on the instances that will be assigned to it, in detriment of those that will not. This is done by jointly training the classifier and the rejector, without penalizing the classifier\u2019s mistakes on instances that the rejector defers to an expert. The approach of Verma et al. (2023  ###reference_b52###) differs in that the rejector and the classifier are trained independently, meaning that the classifier is encouraged to predict correctly on all instances, likely to be deferred or not. However, in the multi-expert setting, the two-stage one-vs.-all approach of Verma et al. (2023  ###reference_b52###) outperforms their adaptation of the softmax loss of Mozannar & Sontag (2020a  ###reference_b38###), which employs joint-learning, due to the same calibration problems observed in the single-expert setting. A more recent joint learning approach proposed by Mozannar et al. (2023  ###reference_b40###) is theoretically shown to enable the system to achieve an improvement in overall performance, as their surrogate loss differs from previous work in that it is realizable -consistent. In more recent work, however, Mao et al. (2024  ###reference_b36###) demonstrate that two-staged learning, the separate training of the classifier and rejector, with their proposed surrogate losses, can also guarantee realizable consistency. We argue that joint learning is not be suitable for real-world applications, as, by design, the instances that are most likely to be deferred are those in which the classifier will perform worse, which would make the system highly susceptible to changes in human availability, should the AI have to predict on instances that were originally meant to be deferred.\nAs previously mentioned, the key barrier to the adoption of current L2D methods is that they require predictions from every human in the team, for every training instance. Current L2D research tackling data-efficient learning focuses only on the single-expert setting, using active-learning principles (Charusaie et al., 2022  ###reference_b8###) to construct a smaller dataset with every human\u2019s predictions for all instances, or employing semi-supervised learning (Hemmer et al., 2023  ###reference_b23###) to impute the missing human predictions.\nWhen deferring, constraints in human work-capacity are rarely considered in multi-expert L2D, where the goal is usually to find the best decision-maker for each instance, disregarding the amount of instances that are deferred to each individual agent. To the best of our knowledge, only Mao et al. (2024  ###reference_b36###) consider control of the amount of deferrals in multi-expert L2D, by allowing for the definition of a constant deferral cost  for each available expert , which is included in their realizable -consistent two stage losses. Similar approaches had been considered in the single-expert case, allowing for the inclusion of a regularization term or expert deferral cost (Mozannar & Sontag, 2020b  ###reference_b39###; Steege, 2023  ###reference_b48###; Narasimhan et al., 2022  ###reference_b41###). While such a formulation allows for regularization of deferral across experts, it would not be adequate for a real-world system, where the availability of experts may vary drastically over time. In a real-world system, different teams of experts may work at different schedules or have days off, which would result in experts being available during certain time intervals while absent in others.\nThe existence of changes in expert availability within real-world HAIC scenarios means that an L2D system must be able to accommodate expert capacity constraints which are defined at inference-time, and not during training. This restriction is similar to that considered by Zhou et al. (2022  ###reference_b54###) in the context of sparsely activated mixture-of-experts models, where the routing strategy (i.e., how tokens are distributed throughout experts) is akin to the task of L2D algorithms. The authors propose allowing for a hard constraint on the number of tokens selected by each expert and the number of experts each token is routed to in inference. This approach allows for dynamic limitation of the compute resources necessary, without needing to retrain their models.\nIn our work, we propose a multi-expert L2D algorithm that can be used in cost-sensitive scenarios, trained with restrictive data requirements, and taking into account individual human work-capacity constraints that are imposed only at inference time."

The minimization of the approximation of the expected value (e.g., via gradient descent) produces a classifier  and a rejector  whose decisions are shown to converge to  and  as the amount of data increases.\nIn this work, rather than deriving a consistent surrogate loss for simultaneously training  and , we train both components separately.

However, the scoring functions  and , obtained in the training steps detailed above, will still be of use in providing calibrated estimates of the probability of correctness.

Finding solutions to these combinatorial problems is not trivial, as solution times grow exponentially with the problem\u2019s size (Huberman et al., 1997  ###reference_b25###). CP-SAT is a parallel portfolio solver, leveraging the available processor cores to run different solution search strategies on each.

We selected CP-SAT in our implementation as it has been repeatedly shown to be the best-performing publicly available solver in a wide array of constraint programming problems in the MiniZinc challenge (Stuckey et al., 2014  ###reference_b49###), where solvers are tasked to finding the optimal or a near-optimal solution within a time-limit. While this solver can find feasible solutions relatively quickly, proving a solution\u2019s optimality can take an extremely long time, meaning that in practice it is often better to set a time limit, having the system return the best solution it found so far.

This guarantees that the minimization of the surrogate losses used to train  and  will result in scoring functions that minimize the misclassification cost instead of the error-rate.

Note, however, that instances may have different misclassification costs, in which case a surrogate for the 0-1 loss is not adequate.

This tabular dataset is comprised of one million synthetically generated bank account opening applications, where the label denotes whether the instance is fraudulent (1) or legitimate (0). The features of each instance contain information about the application and the applicant, and the task of a decision maker (automated or human) is to either accept (0) or reject (1) it.\nThese applications were generated based on anonymized real-world bank account applications, and, as such, this dataset poses challenges typical of real-world high-stakes applications. Firstly, there is a high class imbalance, with 1.1% fraud prevalence over the entire dataset. Furthermore, there are changes in the data distribution over time, often referred to as concept drift (Gama et al., 2014  ###reference_b15###), which can severely impact the predictive performance of ML Models.\nThere are several possible ways for models and humans to cooperate. In previous L2D research, it is a common assumption that any instance can be deferred to either the model or the expert team. However, in real-world settings, due to limitations in human work-capacity, it is common to use an Alert Model to screen instances, raising alerts that are then reviewed by human experts (De-Arteaga et al., 2020  ###reference_b12###; Han et al., 2020  ###reference_b21###). In an alert review setting, humans only predict on a fraction of the feature space, that is, the instances flagged by the Alert Model. We will train a L2D system to work in tandem with the Alert Model, by deferring the alerts in an intelligent manner. We calculate the Alert Model\u2019s alert rate , that is, the fraction of instances flagged for human review, by determining the FPR of the Alert Model in validation. We create distinct alert review scenarios by varying the alert rate .\nWe train the Alert Model to predict the fraud label on the first three months of the dataset, validating its performance on the fourth month. We use the LightGBM (Ke et al., 2017  ###reference_b29###) algorithm, due to its proven high performance on tabular data (Shwartz-Ziv & Armon, 2022  ###reference_b47###; Borisov et al., 2022  ###reference_b5###). Details on the training process of the classifier are given in Section A.1  ###reference_### of the Appendix.\nThis is a cost-sensitive task, where the cost of a false positive (incorrectly rejecting a legitimate application) must be weighed against the cost of a false negative (incorrectly accepting a fraudulent application). Due to the low fraud prevalence, metrics such as accuracy are not adequate to measure the performance of both ML models and deferral systems. The optimization objective used by Jesus et al. (2022  ###reference_b28###) is a Neyman-Pearson criterion, in this case, maximizing recall at 5% false positive rate (FPR), which establishes an implicit relationship between the costs of false positive and a false negative errors. However, for the cost-sensitive learning method described in Section 3.4  ###reference_###, we need to have access to the explicit cost structure of the task at hand.\nIn a cost-sensitive task, the optimization goal is to obtain a set of predictions  that minimize the expected misclassification cost . Assuming that correct classifications carry no cost, the relevant parameter is the ratio , were  and  are the costs of false positive and false negative errors, respectively. The objective is thus\nMinimizing this quantity is equivalent to minimizing the average cost, as division by a constant will not affect the ranking of different assignments. As such, all that remains to be established is a relationship between the Neyman-Pearson criterion and the value of . To to do so, we follow the approach detailed in Section A.2  ###reference_### of the Appendix, which yields the theoretical value . To test performance under variable cost structures, we will conduct experiments for the values . These alternative scenarios are not strictly comparable, as if the cost structure were , the optimization of the Alert Model would not correspond to maximizing the recall at 5% FPR. Nevertheless, we choose to introduce these variations to test the impact on system performance of changing the cost ratio . Combining the different alert rates with these values of , we obtain 6 distinct text scenarios.\nOur expert generation approach is based on instance-dependent noise, in order to obtain more realistic experts, whose probability of error varies with the properties of each instance.\nWe generate synthetic predictions by flipping each label  with probability . In some HAIC systems, the model score for a given instance may also be shown to the expert (Amarasinghe et al., 2022  ###reference_b3###; De-Arteaga et al., 2020  ###reference_b12###; Levy et al., 2021  ###reference_b33###), so an expert\u2019s decision may also depend on an ML model score . We define the expert\u2019s probabilities of error, for a given instance, as a function of a pre-processed version of its features  and the Alert Model\u2019s score , so that the feature scale does not impact the relative importance of each quantity. The probabilities of error are given by\nwhere  denotes a sigmoid function. Each expert\u2019s probabilities of the two types of error depend on five parameters: , and . The weight vector \nembodies a relation between the features and the probability of error. The feature weights are normalized so that we can separately control, via , the overall magnitude of the dependence of the probability of error on the instance\u2019s features. The values of  and  control the base probability of error. The motivation for this approach is explained further in section C.1  ###reference_### of the Appendix.\nThe expected cost resulting from an expert\u2019s decisions is given by\nFor our setup to be realistic, we assume an expert\u2019s decisions must, on average, incur a lower cost than simply automatically rejecting all flagged transactions. Otherwise, assuming random assignment, having that expert in the human team would harm the performance of the system as a whole. As the expert\u2019s average misclassification cost is dependent on the prevalence  and cost structure as defined by , a team of experts with the exact same parameters will have different expected misclassification costs, depending on the alert review scenario in question. For this reason, in each of the six aforementioned settings, we generate a different team of 9 synthetic experts by first fixing their feature weights , and sampling their expected misclassification cost. Then, we calculate the values of  that achieve the sampled misclassification cost, thus obtaining a team of complex synthetic experts with desirable properties within each scenario. Further details on the sampling and expert generation process, as well as a description of each of the expert teams\u2019 properties are available in Sections C.2  ###reference_### and C.3  ###reference_### of the Appendix.\nTo generate realistic expert data availability, we assume that the Alert Model is deployed in months 4-7, and that each alert is deferred to a randomly chosen expert. This generates a history of expert decisions with only one expert\u2019s prediction per instance. To introduce variability to the L2D training process, the random distribution of cases throughout experts was done with 5 different random seeds per scenario. For each of the three  FPR alert rate settings, this results in a set of 2.9K predictions per expert. So that all settings have the same amount of data, for the  FPR alert rate scenarios, we also sample 2.9K predictions from each of the 10 experts.\nIn our experiments, we want to reliably measure the ability of our method to optimize the distribution of instances throughout the human team and the classifier . In real-world scenarios, the cost of querying  is much lower than that of querying a human expert, as the work-capacity of the classifier is virtually limitless. However, in order to ensure that the assignment systems are able to reliably model the human behavior of all experts, we will force the assigner to distribute the instances throughout the expert team and the classifier  in equal amounts. As the expert teams are comprised of 9 experts, this means that 1/10 of the test set will be deferred to each expert/classifier. To introduce variability, we also create four distinct test settings where each expert/classifier has a different capacity, by sampling the values from . As such, for each scenario defined by the  pair, there are a total of 25 test variations, which result from combining each of the 5 training seeds with the 5 different capacity constraint settings."

We observe that, on average, both L2D methods outperform the non-L2D approaches, and that DeCCaF is significantly better in most scenarios. As the number of test seeds (25) is relatively low, the approximation of the 95% confidence interval may be unreliable, as the value shown is derived based on the central limit theorem.\nIn Table 4  ###reference_###, we report the percentage of test variations, for each scenario, in which our method outperforms other deferral baselines. These results demonstrate that, across all scenarios, DeCCaF outperforms the full rejection and the \"Only Classifier\" baseline. Notably, the relative performance of DeCCaF when compared to random assignment changes drastically depending on the scenario properties, performing no better than random assignment for . This again demonstrates how the cost structure and distribution of expert performances has significant impact on the performance of L2D systems. Nevertheless, we observe that DeCCaF performs significantly better than the OvA baseline in 5 out of 6 scenarios, outperforming in both scenarios with .

We consider limited data availability, the existence of human expert work-capacity constraints, cost-sensitive optimization objectives, and significant class imbalance, which are key challenges posed by many high-stakes classification tasks.\nWe propose a novel architecture that aims to better model human behaviour and to globally optimize the system\u2019s performance under capacity constraints. We conducted constrained deferral under a wide variety of training and testing conditions, in a realistic cost-sensitive classification task, empirically demonstrating that variations in the cost structure, data distribution, and human behavior can have significant impact on the relative performance of deferral strategies. We demonstrate that DeCCaF performs significantly better than the baselines in a wide array of testing scenarios, showing that there are benefits to jointly modeling the expert team.\nFor future work, we plan on testing the addition of fairness incentives to our misclassification cost optimization method, to study the impact this system may have in ensuring fairness. For scenarios where the misclassification costs are instance-specific (i.e., transaction fraud), we will also study the possibility of direct cost estimation by using regression models instead of classification.\nFinally, it is important to consider the ethical implications of adopting these systems in real-world scenarios, as these may impact the livelihood of the human experts involved in the deferral process. In a system without intelligent assignment, cases are distributed randomly throughout the human team, ensuring an i.i.d. data distribution for each expert. If a multi-expert L2D system were to be adopted, the subset of cases deferred to each expert would follow a separate distribution. If we consider a highly skilled expert with very high performance throughout the feature space, this system could choose to assign the hardest cases to said expert, damaging their performance. As the performance of analysts is routinely evaluated, this could create unfair disparities across the human expert team, with certain analyst\u2019s performance being degraded while others could be inflated. To tackle this issue, we could periodically assign randomly selected instances to each expert, in order to evaluate them in an i.i.d set, which would also be useful data to retrain the system, as human behaviour may change over time.\nWe hope this work promotes further research into L2D methods in realistic settings that consider the key limitations that inhibit the adoption of previous methods in real-world applications."

In bank account fraud prevention, the consequence of committing a false positive mistake, that is, rejecting a legitimate application, must be weighed against the cost of a false negative mistake, that is, accepting a fraudulent application.

It has been shown by Sheng & Ling (2006  ###reference_b46###) that this relationship between the cost-structure and the classifier\u2019s threshold does not always hold in practice. Secondly, the value of  obtained through this method depends on the classifier trained. A different classifier would yield another value for the optimal threshold according to the Neyman-Pearson criterion, which would lead to a different , despite the task being the same.

They control infrastructures of socio-techno-economic importance, ensuring their stable and sustainable operation.\nSmart ecosystems are governed by digital twins\u2014real-time virtual representations of physical infrastructure. To support the open-ended and reactive traits of smart ecosystems, digital twins need to be able to evolve in reaction to changing conditions.\nHowever, digital twin evolution is challenged by the intertwined nature of physical and software components, and their individual evolution.\nAs a consequence, software practitioners find a substantial body of knowledge on software evolution hard to apply in digital twin evolution scenarios and a lack of knowledge on the digital twin evolution itself.\nThe aim of this paper, consequently, is to provide software practitioners with tangible leads toward understanding and managing the evolutionary concerns of digital twins.\nWe use four distinct digital twin evolution scenarios, contextualized in a citizen energy community case to illustrate the usage of the 7R taxonomy of digital twin evolution.\nBy that, we aim to bridge a significant gap in leveraging software engineering practices to develop robust smart ecosystems.",

+            "text": "Our modern world runs by smart ecosystems\u2014large-scale, decentralized systems, capable of self-organization and self-optimization (Jensen, 2020  ###reference_b14###).\nExamples of smart ecosystems include smart cities (Graciano Neto and Kassab, 2023  ###reference_b9###), smart energy communities (Gramelsberger et al., 2023  ###reference_b10###), and smart grids with renewable components (Hasan et al., 2023  ###reference_b11###).\nMuch like natural ecosystems, smart ecosystems are open-ended and need to allow for continuous changes in their structure and behavior. These evolutionary dynamics, in turn, challenge the technical sustainability (Penzenstadler et al., 2018  ###reference_b19###) of smart ecosystems, i.e., their ability to maintain the quality of service over a prolonged period of time (Hilty et al., 2006  ###reference_b13###).\nTo improve the sustainability of smart ecosystems, proper evolution mechanisms are required to be put in place. While evolution has a substantial body of knowledge in model-driven software engineering (Di Ruscio et al., 2011  ###reference_b7###; Hebig et al., 2017  ###reference_b12###), hybrid cyber-physical components of smart ecosystems, such as digital twins (Kritzinger et al., 2018  ###reference_b15###), give rise to challenges traditional software engineering techniques fall short of addressing.\nDigital twins are real-time, virtual representations of physical system components (Kritzinger et al., 2018  ###reference_b15###).\nThey govern smart ecosystems and provide essential mechanisms and services to assess, simulate, and control the physical infrastructure of smart ecosystems for optimal behavior (Michael et al., 2024  ###reference_b18###). Thus, to ensure the technical sustainability of smart ecosystems, first, the technical sustainability of digital twins must be managed.\nChanges in digital twins boil down to a heterogeneous set of components, including software, hardware, middleware, and IoT devices. The interdependency of concerns severely hinders the applicability of software engineering techniques and even challenges the very understanding of evolutionary needs.\nTo help software engineers apply their expertise in digital twin evolution scenarios, we provide a case-based demonstration of the 7R taxonomy in this paper. The 7R taxonomy of digital twin evolution (David and Bork, 2023  ###reference_b5###) defines seven elementary activities to support the technical sustainability of digital twins.\nThis paper is structured as follows.\nIn Sec. 2  ###reference_###, we elaborate on a case of an evolving smart ecosystem, driven by digital twin evolution.\nIn Sec. 3  ###reference_###, we recommend action points to apply the 7R taxonomy.\nIn Sec. 4  ###reference_###, we draw the conclusions.\nWe provide background information about key concepts in sidebars.\ninnertopmargin=4pt,\nlinewidth=0pt,\nframetitleaboveskip=-frametitlealignment=,\nbackgroundcolor=sidebarbgcolor\n\n{mdframed}\n\n\nThe 7R taxonomy of digital twin evolution\n\nTaxonomies are a form of classification, aiming to systematically organize knowledge of a specific research field or problem. Classification of objects helps to understand the specific field and systematically treat a particular problem. The 7R taxonomy of digital twin evolution (David and Bork, 2023  ###reference_b5###) identifies seven areas of action to react to the evolutionary needs of digital twins.\n\n\n\n\n\n\n\n\n\nRe-calibration of a model parameter is required when the model is not a faithful representation of the physical twin anymore and simulations become incorrect, leading to imprecise assessment, analysis, and control of the physical twin.\nRe-modeling the physical twin might be required in more elaborate cases, e.g., when the model does not reflect the real phenomenon properly. Specific software engineering tasks, such as re-architecting re-packaging a software component might be considered as refinements of this R-imperative.\nReconciliation of data, i.e., updating the data schema and migrating data might be needed when data discrepancies occur, and data might become inconsistent.\n\n\nRe-collecting data is needed when events are missed due to transient errors. It might necessitate reconciliation, re-modeling, and re-calibration.\nRe-deploying the evolved digital twin is needed after at least one of the previous steps has been taken.\nRe-configuration of the physical twin is required after the digital twin has evolved. Re-configuration entails a wide range of potential actions, from changing the settings of a physical component to the installation of new ones.\nReuse of the large amounts of data, knowledge, and know-how that have been amassed during the operation of the digital twin is paramount in ensuring cost-efficient digital twin projects.\n###figure_1###"

+            "text": "To illustrate the usage of the 7R taxonomy (see sidebar), we rely on a practical case of an evolving smart ecosystem, called the citizen energy community.\nEnergy communities enable collective, citizen-driven energy actions to support a clean energy transition (Commission, [n.\u2009d.]  ###reference_b3###). In citizen energy communities (Fig. 1  ###reference_###), citizens and small commercial entities are equipped with energy generation and storage capacity, promoting them to first-class generators of energy. As opposed to traditional regulatory models, a citizen energy community gives rise to a smart ecosystem, in which participation is voluntary and egalitarian; and cyber-physical components compose the infrastructure.\nA digital twin is developed to govern the smart ecosystem (Gramelsberger et al., 2023  ###reference_b10###) from the very beginning.\nThe digital twin provides stakeholders with tools to monitor and optimize energy trading processes, simulate energy provision and usage scenarios, analyze what-if scenarios, and predict maintenance requirements.\nThroughout the lifespan of the system, new features are developed, new components are added, and core elements\u2014often as critical as a power plant\u2014are retired. In the following, we discuss four evolutionary scenarios in an escalating order of impact. By discussing the scenarios through the 7R framework of digital twin evolution for technical sustainability, we demonstrate how to organize the chain of thought about digital twin evolution into a structured set of arguments to support engineering tasks.\n###figure_2### innertopmargin=4pt,\nlinewidth=0pt,\nframetitleaboveskip=-frametitlealignment=,\nbackgroundcolor=sidebarbgcolor\n\n{mdframed}\n\n\nCitizen energy communities\n\nA citizen energy community (Commission, [n.\u2009d.]  ###reference_b3###) is a localized entity, established with the purpose of generating, distributing, supplying, and storing energy. It enables local energy trading and facilitates the purchasing and selling of energy and energy services to optimize local consumption (Gramelsberger et al., 2023  ###reference_b10###). Such a citizen energy community consists of citizens, their buildings, small commercial or public entities consuming energy, and different sources producing energy including the citizens and small commercial or public entities.\nEnergy communities are crucial in driving the clean energy transition.\n\n\n\n\n\nDigital twins of citizen energy communities\n\nA digital twin of a citizen energy community provides a faithful virtual replica of the overall socio-techno-economic system. By that, the digital twin enables the assessment of key indicators, e.g., of sustainability and overall system health, and supports the continuous improvement and evolution of the ecosystem. A digital twin also helps monitor and optimize energy trading processes (Tsado et al., 2022  ###reference_b23###), simulate energy provision and usage scenarios, detect incorrect sensor information, and predict maintenance tasks of power lines, energy storages, or other physical components."

In a data-first approach, the physical twin is re-configured, and subsequently, data collection and reconciliation start immediately to drive model creation in a deductive fashion. The discussion of Scenario 3 in the running example followed a data-first view. Alternatively, in a model-first approach, the re-configuration of the physical twin is followed by re-modeling, re-calibration, and re-deployment of the digital twin. The benefit of this approach is that models can be used to re-generate data schemas and processing scripts, and thus, data collection can commence smoothly, almost without manual intervention. Software companies adopting model-driven practices (Schmidt, 2006  ###reference_b20###) might venture into model-first evolutionary processes, but the data-first mindset is still prevalent in practice."

+    "abstract": "The current winning recipe for automatic summarization is using proprietary large-scale language models (LLMs) such as ChatGPT as is, or imitation learning from them as teacher models. While increasingly ubiquitous dependence on such large-scale language models is convenient, there remains an important question of whether small-scale models could have achieved competitive results, if we were to seek an alternative learning method\u2014that allows for a more cost-efficient, controllable, yet powerful summarizer. We present InfoSumm, a novel framework to distill a powerful summarizer based on the information-theoretic objective for summarization, without relying on either the LLM\u2019s capability or human-written references. To achieve this, we first propose a novel formulation of the desiderata of summarization (saliency, faithfulness and brevity) through the lens of mutual information between the original document and the summary. Based on this formulation, we start off from Pythia-2.8B as the teacher model, which is not yet capable of summarization, then self-train the model to optimize for the information-centric measures of ideal summaries. Distilling from the improved teacher, we arrive at a compact but powerful summarizer with only 568M parameters that performs competitively against ChatGPT, without ever relying on ChatGPT\u2019s capabilities. Extensive analysis demonstrates that our approach outperforms in-domain supervised models in human evaluation, let alone state-of-the-art unsupervised methods, and wins over ChatGPT in controllable summarization.",

In order to reduce the inference cost, one maybe particularly tempted to distill a compact summarizer from the LLM: by collecting some documents, instructing the LLM to summarize them, and supervising a small model to simply imitate the generations (Xu et al., 2023  ###reference_b52###; Sclar et al., 2022  ###reference_b43###). Despite its intuitive appeal, this process does not involve how we explicitly define a good summary\u2014the feasibility of data generation is fundamentally dependent on the LLM\u2019s capability to follow the instruction. With no quantifiable objective for summarization, our best option is to use the largest and strongest LLM as the teacher, and enumerate as much imitation data as possible from it (Li et al., 2023  ###reference_b31###; Mukherjee et al., 2023  ###reference_b37###). Despite this increasing dependence on large LMs, it is still unclear whether the distilled summarizer will fully generalize across diverse use cases (Gudibande et al., 2023  ###reference_b15###), whether it be zero-shot adaptation to unseen domains or generating controllable summaries.\nIn this work, we shift our attention from using a larger and stronger teacher model, and show that even the small, off-the-shelf LMs can teach themselves to excel at summarization, provided we define an information-theoretic objective for summarization. Concretely, we propose that the three evaluative dimensions of summarization\u2014saliency, faithfulness and brevity\u2014can be incorporated into a unified search objective, where we look for a summary  that maximizes its point-wise mutual information (PMI) with the document  under a length constraint. By self-improving the teacher through expert iteration (Anthony et al., 2017  ###reference_b1###) to align with our objective, we yield a high-quality summarization dataset only from a small teacher LM not tuned for summarization. This method, InfoSumm (Figure 1  ###reference_###), decouples what we expect to generate (i.e., the explicit search objective for summarization) from how we generate them (i.e., data-generating LM), allowing us to distill a powerful summarization model without human-written references or an LLM already competent at summarization. Compared to a prior work that distills from a small, off-the-shelf LM (Jung et al., 2023  ###reference_b22###), InfoSumm targets substantially longer, document-level summarization, and operates entirely without human-supervised critics.\nApplying our method, we train a 568M summarizer with the dataset generated from Pythia-2.8B (Biderman et al., 2023  ###reference_b3###), an off-the-shelf autoregressive LM that itself cannot reliably summarize a given document. We test our model on diverse tasks spanning news summarization, zero-shot generalization to unseen domains, and controllable summarization. Our model, despite its small scale, exhibits surprisingly strong performance compared to the state-of-the-art: it significantly outperforms all unsupervised methods in reference-based evaluation, improving more than 2 R-1 points across benchmarks. In GPT-4 and human evaluation, our system is even preferred to the in-domain reference-supervised models, and outperforms 175B ChatGPT with a simple re-ranking approach. Notably, our model, as a compact, expert model for summarization, exhibits significantly better controllability than prompting ChatGPT (e.g., to generate a long, highly specific summary of the given document), establishing a promising alternative to imitating human references or LLM-generated summaries.\n###figure_1###"

In this section, we first quantify these desiderata of summarization in an information-theoretic perspective, then discuss how they can be unified as maximizing the mutual information between the document  and summary  subject to a length constraint on .\nSaliency  A good summary  should well represent the salient information of the document; information-wise, it should effectively reduce the uncertainty of document  without directly observing it. To empirically measure saliency, we employ a masked language model (MLM)\u2014by masking the tokens in the document  to produce , then measuring how well an MLM can recover  from  when given the summary . Leveraging this idea, we introduce a saliency critic :\nConcretely, we normalize the score with the likelihood of reconstructing  from  without , as some masks maybe easily inferred without observing .111While we do not require a specific masking strategy to produce , we find that masking salient keywords identified by TF-IDF (Laban et al., 2020  ###reference_b29###) allows efficient approximation in practice. The critic operates by filtering out  pairs with the normalized score lower than a threshold, where  is a hyperparameter. The compression ratio  in the threshold reflects the trade-off between summary length and saliency\u2014i.e., a longer summary should better preserve the information of the document. Notably, the proposed critic requires only a self-supervised MLM as a proxy model, as opposed to human-supervised critics in Jung et al. (2023  ###reference_b22###)222Specifically, Jung et al. (2023  ###reference_b22###) employs a supervised NLI model as a critic for sentence summarization, which does not generalize well to document-level inputs..\nFaithfulness  Neural summarizers often suffer from hallucination, i.e., adding information to the summary that was not present in the original document (Chen et al., 2022  ###reference_b6###; Laban et al., 2022  ###reference_b30###). Under our formulation, faithfulness can be measured in a reverse direction of saliency, by recovering the summary  from  given the document :\nIntuitively, masks on  would be easier to infer given , if  did not add additional information not in . Unlike the saliency critic, we do not include the compression ratio in the filtering threshold, as we expect a good summary to be always faithful to the document regardless of its length.\nBrevity  Finally, a summary  should be a brief representation of the input , evaluated by the compression ratio between the summary and the document:\nInformation-Maximizing Objective  Essentially, the saliency and faithfulness critics can both be considered as filtering based on the PMI between  and , where the two critics differ in how they approximate the mutual information. Specifically, in case of the saliency critic,\nThe same derivation applies to faithfulness critic. Therefore, incorporating all 3 dimensions above, our objective for distilling text-summary pairs can be crisply described as\nSearching for a pair  of fluent text that maximizes its mutual information PMI, subject to .\nBroadly seen, the mutual information between the input data and its compression have been utilized in prior works, primarily as a metric for unsupervised text evaluation (Kim et al., 2022  ###reference_b26###; Vasilyev et al., 2020  ###reference_b49###) and feature extraction (Padmakumar & He, 2021  ###reference_b40###; Covert et al., 2023  ###reference_b7###). Compared to these approaches, we formulate PMI maximization as a unified objective for abstractive summarization, which can be optimized even with an off-the-shelf LM by rejection sampling with the self-supervised critics defined above."

Our key idea is to self-train the teacher  through expert iteration (Anthony et al., 2017  ###reference_b1###) to align with our information-maximizing objective, yielding an improved data generator  for summarization prior to distilling a student.\nGenerating Initial Dataset  We start by generating an initial dataset  from the off-the-shelf teacher , by over-generating candidate document-summary pairs with the teacher and subsequently filtering them using the critics defined in \u00a72.1  ###reference_###.\nTo generate the candidate pairs, we take a simple auto-regressive approach\u2014we first sample text from , then just take 1-5 leading sentences as a summary of the remaining content, i.e., . Here,  is a simple prefix for better generation quality (e.g., New York, (CNN) \u2013 to promote news-style generation). We find this approach particularly effective for two reasons. First, it is an easy way to condition the generation of  on , without fine-tuning the autoregressive teacher . Next, the leading sentences often contain the most salient information of the document, hence have been used as a useful proxy of summary in previous works (e.g., Zhu et al. (2019  ###reference_b62###)).\nA limitation of the autoregressive approach, however, is that it generates a long document conditioned on a handful of sentences in the beginning \u2013 as the generation gets longer, it easily loses coherence from the original context. To mitigate this issue, we devise a decoding algorithm inspired by Product of Experts (Hinton, 2002  ###reference_b19###; Liu et al., 2021  ###reference_b33###) on top of :\nBy penalizing the unconditional likelihood of the document, we encourage the teacher to attend more to the leading sentences  while generating . Note that if we set , , therefore  is generated to maximize its PMI with the summary . Using the decoding algorithm, we distill the initial dataset  by over-generating candidate set  of document-summary pairs, then filtering it using the critics defined in \u00a72.1  ###reference_###:\nDistilling Expert Summarizer  While the critic models and decoding algorithm effectively implement our search objective, the sampling efficiency of the generated pairs is of central concern when distilling a large-scale dataset. That is, most candidate pairs in  are unlikely to pass the critic filtering stage, as our initial teacher model is assumed to be not aligned for summarization.\nTo resolve the bottleneck of low sampling efficiency, we perform a loop of expert iteration (Anthony et al., 2017  ###reference_b1###; Silver et al., 2017  ###reference_b44###) on the teacher , where the off-the-shelf LM is supervised on its own generated, high-quality pairs. Concretely, instead of distilling a student summarizer  with , we self-train the teacher  to maximize , yielding an improved teacher . By training exclusively on high-quality pairs identified by the critics, the teacher model is gradually aligned with our search objective; as we show in the later section, even a single step of expert iteration dramatically boosts the sampling efficiency of the teacher model. Compared to previous works on expert iteration, we yield a specialized data generator entirely from pre-trained LMs, without resorting to ground-truth references (Zelikman et al., 2022  ###reference_b57###) or a human-supervised verifier (Lightman et al., 2023  ###reference_b32###).\nFinally, we distill an expert summarizer  from the improved teacher . First, a large-scale dataset  is distilled from the improved teacher , following the same process with . Then, we fine-tune a student LM into an expert summarizer  by maximizing , i.e., the conditional log-likelihood of  given . As a byproduct of this process, we obtain a large-scale, high-quality summarization dataset  that can be interpreted and reused, e.g., to train a summarization model without re-iterating the overall distillation process.\nEndowing Controllability  Controllable summarization has recently emerged as an important research direction (Fan et al., 2018  ###reference_b11###; He et al., 2022  ###reference_b18###), allowing users to customize diverse aspects of the generated summary (e.g., length and specificity). Under InfoSumm, a controllable summarizer can be trained simply by post-hoc annotating the generated data with the control attributes (for more details, see Appendix B  ###reference_###). Moreover, as our framework operates with a small LM as a data generator, we can down-sample over-generated pairs to increase the diversity of control attributes. After annotating control attributes, a student can be trained to be controllable by prepending the control code (Keskar et al., 2019  ###reference_b23###) as an instruction to the input document."

(2021a  ###reference_b9###), as well as zero-shot prompted ChatGPT (gpt-3.5-turbo). We also consider an in-domain supervised baseline PEGASUS, fine-tuned on the respective train sets of the benchmarks. For metrics, we report ROUGE, BERTScore (Zhang et al., 2020b  ###reference_b59###) and average G-EVAL (Liu et al., 2023b  ###reference_b35###), a reference-less metric based on GPT-4 known to better correlate with human judgements of summary quality.\nResults  We present our quantitative results in Table 1  ###reference_###. InfoSumm-0.5B significantly outperforms summarization-specific unsupervised baselines \u2013 including Summary Loop trained with in-domain articles of CNN/DM, and WikiTransfer that leverages the stylistic bias of each benchmark (hence not considered to be strictly zero-shot). Overall, our model marks similar performance across metrics with ChatGPT, an order of magnitude larger, human-aligned LLM. In GPT-4 evaluation on XSUM, it even outperforms PEGASUS, the same base model PEGASUS supervised on the in-domain references.\nHuman Evaluation  To better compare the quality of model-generated summaries, we conduct human evaluation. We generate summaries for 200 CNN/DM articles with each system, then ask 6 annotators to score their fluency, faithfulness and saliency following Stiennon et al. (2022  ###reference_b45###). To adjust the confounding effect of summary length, we sample only those articles for which all systems output summaries with the same number of sentences. To minimize subjectivity, we use strict 3-level Likert scale, leading to high inter-annotator agreement (Krippendorff  ###reference_b28###\u2019s alpha=0.65; substantial agreement).\nThe left part of Figure 2  ###reference_### presents the results. We find that summaries from InfoSumm-0.5B outperform PEGASUS across all dimensions, and are considered to be more faithful than ChatGPT generated summaries. In Appendix E.2  ###reference_###, we additionally conduct pairwise human evaluation of InfoSumm against the baselines. We find that summaries from InfoSumm are at least of equal quality with ChatGPT for more than 80% of the time, and are preferred to PEGASUS for more than 50% of the time, demonstrating the strong performance of our distilled model."

We compare InfoSumm-0.5B against three zero-shot baseline summarizers: Summary Loop, PEGASUS fine-tuned on CNN/DM train set, and zero-shot prompted ChatGPT.\nIn Table 2  ###reference_###, we find that InfoSumm-0.5B outperforms strong models in this setup, generating similar quality summaries as prompting ChatGPT. Notably, the results imply that InfoSumm generalizes better than training on human-authored datasets: InfoSumm-0.5B, trained on our distilled summaries, performs better in unseen domains than the same base model PEGASUS, fine-tuned on human-written summaries of CNN/DM.\nFine-tuning to Unseen Domains \nOne strength of a compact expert model is that it can be fine-tuned, to better follow the specific style and domain of benchmark references. This motivates us to consider another use-case of InfoSumm, where a model is first distilled into a performant summarizer using synthetic data, then is further supervised on human-authored references to better adapt to an unseen domain.\nIn Table 3  ###reference_###, while initial fine-tuning on CNN/DM (PEGASUS) degrades the final model performance on unseen domains, InfoSumm-0.5B improves over vanilla PEGASUS after fine-tuning.333We focus on reference-based evaluation, as fine-tuning does not improve G-Eval for both PEGASUS and InfoSumm-0.5B. We attribute this to the relatively narrow distribution of summary styles in commonly used summarization datasets (Tejaswin et al., 2021  ###reference_b46###), including CNN/DM. As we show in \u00a73.5  ###reference_.3###, our dataset exhibits substantially larger scale, more extensive coverage of the summary space compared to the existing benchmarks, allowing the model to readily adapt to a specific summary style through fine-tuning."

While large-scale supervision is crucial for reliable controllability, human-authored train set is hard to scale. Accordingly, PEGASUS fine-tuned on the 4K samples of MACSum train set yields sub-optimal performance, although the references were curated by humans. Meanwhile, our model better correlates to the control codes than ChatGPT, even when the LLM was given 5-shot in-domain demonstrations. The result substantiates that while a textual description of constraints could signal some degree of control to LLMs, it may not suffice to control more sparse and fine-grained composition of attributes (Chen et al., 2023  ###reference_b5###)."

Thus, it is reasonable to ask whether the critic models are all we need, i.e., strong performance can simply be achieved by re-ranking summaries generated from existing systems (e.g., ChatGPT). To validate this hypothesis, we test best-of-10 approach on top of ChatGPT and InfoSumm-0.5B: we first sample 10 summaries per document, then output the generation with the largest sum of faithfulness and saliency score.\nIn human evaluation (Figure 2  ###reference_### and Appendix E.1  ###reference_###), best-of-10 on ChatGPT slightly improves its faithfulness and saliency, but undermines the fluency of the generated summaries. This is in contrast to our method, where best-of-10 consistently improves in all evaluated aspects. The results show that (1) optimizing for PMI maximization indeed improves the human perception of faithfulness and saliency for both LLM and InfoSumm generated summaries, but (2) unlike our model, a moderate sample size of 10 may not be enough for meaningful exploration with ChatGPT, as the model has not been trained to align with our search objective.\n###figure_3### Analyzing Data Diversity \nWe directly evaluate the diversity of the distilled dataset against human-curated benchmarks widely used for news summarization. We first compare the summary length statistics and lexical diversity of each dataset (Table 5  ###reference_###). To measure lexical diversity, we follow Jung et al. (2023  ###reference_b22###) to report 2/3-gram entropy, along with mean segmented token type ratio (MSTTR; Torruella & Capsada (2013  ###reference_b47###)) of the summaries. In addition, we analyze the summary style distribution of each dataset (Figure 3  ###reference_### and Appendix E.4  ###reference_###), by categorizing summaries into 18 style groups proposed in MACSum.\nThe results demonstrate that our dataset, as a purely synthetic corpus, is not only larger in sample size but also is substantially more diverse than existing datasets. As shown in Appendix E.4  ###reference_###, human-authored datasets are typically skewed to a narrow region of style distribution\u2014in XSUM, more than 70% of the reference summaries fall into short, less extractive and less specific group. Our dataset, on the other hand, covers significantly broader region of summary styles, along with consistently higher lexical diversity.\nAnalyzing Sampling Efficiency  \nIn Appendix E.3  ###reference_###, we conduct an ablation study on InfoSumm, specifically focusing on the sampling efficiency of the framework (i.e., the ratio of candidate summary pairs that pass all the critics). We leave the full results in Table 10  ###reference_###, and summarize the results here. First, we find that the sampling efficiency of initial teacher prior to expert iteration is only 0.9%, indicating the importance of expert iteration for large-scale distillation. However, we also find that multiple steps of expert iteration can over-optimize the teacher, leading to less diversity in generated data despite better sampling efficiency. We also find that PMI-maximization decoding (Eq. 5  ###reference_###) improves the sampling efficiency by 4% compared to temperature-based sampling, representing its usefulness as inference-time algorithm to efficiently search for high-quality samples. See Appendix 3.5  ###reference_.SSS0.Px1### for additional ablation results that focus on distilled model performance.\nWe also test whether expert iteration indeed improves the performance of the distilled summarizer. Specifically, we train an additional summarizer by directly fine-tuning PEGASUS-large on , the initial dataset of 140k document-summary pairs generated from the off-the-shelf teacher .\nThe performance of this configuration against the full InfoSumm is shown in Table 6  ###reference_###. InfoSumm, trained with the large-scale summarization dataset generated by the improved teacher, yields consistently better scores in both reference-based (ROUGE-L) and reference-free evaluation (G-Eval). Surprisingly however, compared to the various unsupervised summarization models in Table 1  ###reference_###, our model trained without expert iteration already outperforms majority of baselines in both CNN/DM and XSUM. The result shows that while expert iteration clearly benefits the student by scaling the training data, distilling with the information maximizing objective is as important to yield a reliable summarizer.\nDoes PMI align with human evaluation? \nWe have shown through best-of-n analysis that optimizing for the PMI between the document and summary improves human evaluation results. In Appendix D  ###reference_###, we further verify this by comparing the human-judged quality of references in XSUM against the PMI values estimated by the two critics of InfoSumm. Overall, we find that the estimated PMI is an excellent predictor of human-evaluated quality, especially in the two tails of the score distribution (i.e., when the pair is certainly of low-quality or high-quality). We also find that PMI estimation can often reveal annotation error in the widely-used dataset, indicating that our proposed objective can serve as a useful tool for filtering high-quality data for summarization."

While these methods typically require carefully designed training loop or reward shaping process (Yang et al., 2020  ###reference_b53###), their performance often fall behind supervised models. Apart from the conventional methods, recent findings report that LLMs such as ChatGPT excel at summarization, surpassing the quality of human-supervised models without task-specific fine-tuning (Goyal et al., 2023  ###reference_b13###; Zhang et al., 2023a  ###reference_b60###). Subsequent works also show that a compact summarizer can be trained by imitating LLM-generated summaries (Sclar et al., 2022  ###reference_b43###; Xu et al., 2023  ###reference_b52###). Beyond LLM distillation, Jung et al. (2023  ###reference_b22###) shares similar motivation to ours, presenting Impossible Distillation that distills a strong task model from a small, off-the-shelf teacher model. While Impossible Distillation is only applicable to sentence level tasks and requires a supervised NLI model, we target a more complex task of abstractive summarization with document-level inputs and operate entirely without human supervision.\nGenerating Data with Language Models  Beyond summarization, a growing line of works proposes to directly generate a dataset using language models, tailored to specific domains and tasks such as commonsense knowledge (West et al., 2022  ###reference_b50###; Brahman et al., 2023  ###reference_b4###), mathematical / textual reasoning (Yu et al., 2023a  ###reference_b54###; Mukherjee et al., 2023  ###reference_b37###) and social dialogues (Kim et al., 2023  ###reference_b25###). Nonetheless, challenges abound in automatic data generation \u2013 while the quality of data is a critical factor in downstream performance (Gunasekar et al., 2023  ###reference_b16###), even the strongest LMs suffer from unexpected mistakes (Jones et al., 2023  ###reference_b20###; Jung et al., 2022  ###reference_b21###) and lack of diversity in its generations (Yu et al., 2023b  ###reference_b55###). Several techniques have been introduced to improve the data quality, such as verifier-guided sampling (Uesato et al., 2022  ###reference_b48###; Lightman et al., 2023  ###reference_b32###) and attributed prompting (Yu et al., 2023b  ###reference_b55###; Yue et al., 2023  ###reference_b56###; Eldan & Li, 2023  ###reference_b8###), albeit in limited domains. Aligning with these works, we show that an explicit formalization of the target task can significantly boost the quality of generated dataset, and further demonstrate that prompting a larger, stronger LLM is not the only way to distill a performant summarization model."

We find that this way of prompt construction not only encourages the fluency of LM, but also significantly improves the diversity of generation compared to sampling without a prompt. While generating both the summary and article, we use top-p threshold of  with temperature = . We first generate summary by sampling 1-5 sentences conditioned on , where the number of sentences are randomly chosen. Then, the article is generated by autoregressively conditioned on both  and the summary. We do not fix the number of sentences in the article, and generate until the max number of tokens are reached (1024 for our experiments).\nWe use T5-large, a masked language model with 770M parameters as the backbone for the faithfulness and saliency critics. To determine critic thresholds, we run a series of small-scale experiments to generate 1K samples from  and manually inspect the summary quality. Based on the results, we set ,  and . Intuitively,  constrains that when the summary length is 10% of the original document, the likelihood of accurately inferring the masked tokens has to be 40% higher when an MLM is provided with the summary. We qualitatively find that while the high threshold leads to low sampling efficiency with the initial teacher, it improves the quality of the distilled dataset and hence leads to better performance of the end-stage student model.\nAfter expert iteration, we train PEGASUS-large, an encoder-decoder pre-trained LM with 568M parameters on the 4.5M samples distilled from the improved teacher . We fine-tune the model for 2 epochs with batch size 64 and max target tokens = 128. For all other hyperparameters, we use the same setting as chosen in the original paper (Zhang et al., 2020a  ###reference_b58###).\nFor our main experiments, we report ROUGE, BERTScore along with G-Eval. G-Eval is a model-based metric computed by prompting an LLM (e.g., ChatGPT, GPT-4) with chain-of-thought style prompt for text evaluation. Specifically, we use GPT-4 as the base LM for G-Eval, averaging 1-5 Likert scale scores averaged across 4 dimensions (coherence, consistency, fluency and saliency), following the setup of the original paper (Liu et al., 2023b  ###reference_b35###). To instruct GPT-4, we use the prompt in the official implementation. Although G-Eval shows substantially higher correlation with human judgements of summary quality compared to conventional metrics, Liu et al. (2023b  ###reference_b35###) also reports that GPT-4 is biased toward LLM generations, assigning higher scores to summaries from ChatGPT than the baselines (including human-authored summaries).

For example, to annotate the length of summary , we define\nIdeally, the thresholds  and  should reflect how humans perceive the control attributes \u2013 e.g., how short a summary should be in order to be perceived as short by humans. To this end, we define the thresholds based on the statistics of human-written summaries in MACSum train set. For example, the threshold  between the short and medium length summaries is defined as the median length of short summaries and medium length summaries authored by human annotators. The specific values of the thresholds are as shown in Table 8  ###reference_###.\nWe annotate 1M subset of distilled dataset following the above process. Then, we train the student model on the distilled dataset, to generate a controlled summary when it is prompted with a specific instruction for control attributes (e.g. Generate a long summary with low extractiveness and high specificity, focusing\non given keywords). We provide examples of controlled summaries generated by InfoSumm-0.5B in Appendix F  ###reference_###.\nFor quantifiable attributes i.e., length, extractiveness and specificity, we report the control correlation (CC) of each summarization system. Control correlation measures how well a system follows the given instruction for a specific control dimension. Specifically, for a control attribute (e.g., length) with a control value pair  (e.g., short, medium), we first generate two summaries  and  for the same document but with the different control values  and , while all other attributes are unchanged. Then, CC is defined as\nwhere  defines the distance between the two control values, e.g.,  = 1, . Note that CC can be either positive or negative; when CC is negative, it indicates that the model has a negative correlation with the control instruction. We evaluate the system\u2019s average CC over a control dimension as the arithmetic mean over all samples in MACSum test set. For keyword and overall summary quality evaluation, we conduct human evaluation; see details in Appendix C  ###reference_###."

Following the same setup as in the main section, we conduct human evaluation to evaluate the quality of 100 reference summaries random-sampled from XSUM dataset. Then, we plot the human-judged saliency (faithfulness) of each summary against the PMI estimated by our proposed saliency (faithfulness) critic. We specifically choose XSUM because its reference summaries are bounded to be a single sentence, making it easier to control the confounding effect of length.\nWe present the results in Figure 5  ###reference_###. In both dimensions, the estimated PMI exhibits positive correlation with the human-judged quality of reference summaries; maximizing PMI leads to more salient and faithful summaries, judged by humans. In addition, we find that particularly low value of estimated PMI often indicates annotation error \u2013 e.g., the reference summary is completely irrelevant to the document, stating \u201dAll images are copyrighted\u201d. This finding shows that even the widely-used summarization benchmarks are noisy, and PMI estimation can serve a useful tool for data cleaning prior to supervising a summarizer.\nNotably, PMI becomes a better predictor of the human-judged quality in the two tails of the score distribution (i.e., when the document-summary pair is certainly low-quality or high-quality), while the prediction gets slightly noisier in the middle range \u2013 this is expected, as even the human annotators show less agreement for the pairs with ambiguous quality. In fact, the result supports our choice of expert iteration as the learning algorithm - while directly optimizing for PMI with online learning may include training with the noisy reward in the middle, our method discards those pairs with susceptible estimated quality, training with only the high-quality samples we are more confident about."

While re-ranking the supervised model\u2019s summaries consistently improves the quality of summary across fluency, faithfulness and saliency, it still substantially falls behind InfoSumm, indicating that the proposed information maximizing objective provides better supervision signal than imitating reference summaries of CNN/DM dataset.\nTo better compare the quality of summaries, we provide pairwise human evaluation results. Following the setup of prior works (Goyal et al., 2023  ###reference_b13###; Stiennon et al., 2022  ###reference_b45###), we ask 6 annotators to determine which summary is better. We use 200 CNN/DM articles and compare InfoSumm-0.5B, ChatGPT and in-domain supervised PEGASUS, with and without re-ranking.\nThe results are shown in Table 9  ###reference_###. We find that summaries from InfoSumm are evaluated to be at least equal quality with ChatGPT for more than 80% of the time, both with and without re-ranking. Our model is consistently preferred to PEGASUS supervised on CNN/DM train set, winning for more than 50% of the samples in both settings.\nWe conduct an ablation study on InfoSumm, focusing on the sampling efficiency of the framework in Table 10  ###reference_###. Concretely, we quantify the sampling efficiency as the ratio of candidate summary pairs generated by the teacher that pass all the critics.\nFirst, we ablate the expert iteration and directly measure the sampling efficiency of the initial teacher  (No expert iteration). As expected, the off-the-shelf LM\u2019s sampling efficiency is near zero, indicating the importance of expert iteration for large-scale distillation. However, we also find that multiple steps of expert iteration can lead to over-optimizing the data generator. While 2 steps of expert iteration yields slightly better efficiency than a single step (2 expert iteration steps), we qualitatively find that it significantly reduces the diversity of generated data due to over-fitting the teacher model. We also consider an ablation (No PMI-maximization decoding) on our decoding algorithm by replacing it with Nucleus Sampling. The sampling efficiency in this case degrades by 4% than the original pipeline, attesting to the usefulness of the inference-time algorithm to efficiently search for high-quality samples.\nIn Figure 7  ###reference_###, we plot the summary style distribution of 4 widely-used summarization datasets\u2014CNN/DM, XSUM, Gigaword and WikiHow. Note that all these datasets were curated by humans and are of large-scale, consisting of least 200K train samples up to 3.8M samples in Gigaword. Nonetheless, compared to InfoSumm, the reference summaries in each dataset are skewed to distinctive regions of summary style."

While our approach allows the generation of a reusable, high-quality dataset for summarization, in principle, the proposed objective can be optimized using alternative training methods such as online reinforcement learning. Therefore, a straightforward extension to InfoSumm would be to compare the performance and robustness of summarizers optimized through different learning techniques.\nAs conventional metrics such as ROUGE fail to accurately evaluate model outputs, recent works propose to further fine-tune summarizers with human preference data, e.g., through reinforcement learning (Stiennon et al., 2022  ###reference_b45###; Wu et al., 2021  ###reference_b51###). Although we show through extensive experiments that InfoSumm is capable of distilling a powerful summarizer from an off-the-shelf teacher, our search objective may fall short of representing the subtle nature of human preferences. Nonetheless, as demonstrated by the superior fine-tuning performance of InfoSumm-0.5B to specific benchmarks, we envision that InfoSumm can still function as a useful base model for learning from human feedback. In this scenario, InfoSumm-0.5B can be harnessed as a strong base model for summarization, equipped with better initial performance and transferability than the models naively fine-tuned on human-authored references.\nIn addition, the high level methodology of InfoSumm can be generalized to tasks beyond summarization. While different tasks would require different set of critic models, the method can be adopted to tasks where the correctness of input-output can be measured and evaluated, either through an external verifier (e.g., commonsense reasoning; Liu et al., 2023a  ###reference_b34###) or through symbolic execution (e.g., code generation; Haluptzok et al., 2023  ###reference_b17###). The distillation stage of InfoSumm can also be improved by incorporating advanced learning techniques such as BRIO (Liu et al., 2022  ###reference_b36###), beyond maximizing conditional likelihood of the summaries in the generated dataset."

Fill your kitchen sink with very hot water, enough water, that is more than half, but less than to the very top. Add a squirt of dish soap in the water, and on a sponge, and make sure your sponge is wet, with dish soap on it. Put in all the cups into the hot water in sink and start cleaning. Once you are done with the cups, you can wash your plates, cutlery and cooking utensils. Coffee stains, and other stains, need some work to get clean, so scrub a little harder, but also let all the cups soak in the hot water longer, for that gets the stains looser, and easier to get clean. Rinse off the soap and water, and make sure you rinse well in very hot water. Some people like to buy a rack to hang your cups, so the water drips off the cups. But, if you want your dishes to be done quickly, hang your cups on a rack. When you\u2019re done washing all the dishes, wipe the dishes with a cloth towel. You might want to wash your towel after drying the washer. Put away your clean cups, and other dishes in a cupboard, or somewhere safe from getting dirty, and where you can grab one with out breaking a cup or other dish. Purchase and place a kitchen rug near the sink. If you drop a cup during the washing, it\u2019s less likely to be broken and one under where you will gather cups from time to time.</span>\n</span>\n</td>\n</tr>\n<tr class=\"ltx_tr\" id=\"A6.T14.1.1.2.2\">\n<td class=\"ltx_td ltx_align_justify ltx_align_middle ltx_border_t\" id=\"A6.T14.1.1.2.2.1\" style=\"width:47.7pt;\">\n<span class=\"ltx_inline-block ltx_align_top\" id=\"A6.T14.1.1.2.2.1.1\">\n<span class=\"ltx_p\" id=\"A6.T14.1.1.2.2.1.1.1\"><span class=\"ltx_text ltx_font_bold\" id=\"A6.T14.1.1.2.2.1.1.1.1\">Summary 1</span></span>\n</span>\n</td>\n<td class=\"ltx_td ltx_align_justify ltx_align_middle ltx_border_t\" id=\"A6.T14.1.1.2.2.2\" style=\"width:329.9pt;\">\n<span class=\"ltx_inline-block ltx_align_top\" id=\"A6.T14.1.1.2.2.2.1\">\n<span class=\"ltx_p\" id=\"A6.T14.1.1.2.2.2.1.1\"><span class=\"ltx_text ltx_font_bold\" id=\"A6.T14.1.1.2.2.2.1.1.1\">Control Codes:</span> <span class=\"ltx_text ltx_font_italic\" id=\"A6.T14.1.1.2.2.2.1.1.2\">None (Unconstrained generation)</span>\n<br class=\"ltx_break\"/><span class=\"ltx_text ltx_font_bold\" id=\"A6.T14.1.1.2.2.2.1.1.3\">Output:</span> To clean coffee mugs and other dirty cups, fill a kitchen sink with hot water and add a squirt of dish soap.

+    "abstract": "This paper proposes a vision-based framework for a 7-degree-of-freedom robotic manipulator, with the primary objective of facilitating its capacity to acquire information from human hand demonstrations for the execution of dexterous pick-and-place tasks. Most existing works only focus on the position demonstration without considering the orientations. In this paper, by employing a single depth camera, MediaPipe is applied to generate the three-dimensional coordinates of a human hand, thereby comprehensively recording the hand\u2019s motion, encompassing the trajectory of the wrist, orientation of the hand, and the grasp motion. A mean filter is applied during data pre-processing to smooth the raw data. The demonstration is designed to pick up an object at a specific angle, navigate around obstacles in its path and subsequently, deposit it within a sloped container. The robotic system demonstrates its learning capabilities, facilitated by the implementation of Dynamic Movement Primitives, enabling the assimilation of user actions into its trajectories with different start and end points. Experimental studies are carried out to demonstrate the effectiveness of the work.",

+            "text": "With the continued expansion of the robotics industry, the scope of interactions between robots and humans in everyday life is poised to increase, thereby placing higher demands on the intelligent evolution of robots. Conventional methodologies for robot learning detect the environment through sensors, coupled with extensive computational processes executed within simulated environments, all in the pursuit of developing logical motion planning strategies for robots during task execution [1  ###reference_b1###]. This approach, however, requires substantial time and has high requirements on hardware performance. In stark contrast, human execution of analogous tasks is simple and intuitive. Therefore, one promising way to enhance the robot intelligence involves learning from human demonstration, wherein humans assume the role of instructors. Within this framework, robots imitate and learn from demonstrations (LfD), thereby elevating their behavioral dexterity.\nOne work of LfD involves the acquisition of human-guided instructional data. Conventional approaches to data collection employ mechanical sensors to gather information from human actions. In [2  ###reference_b2###], Chen et al. utilized motion capture markers and an Inertial Measurement Unit (IMU) to capture the foot movement. In parallel with advancements in computer vision technologies, the utilization of cameras has emerged as an alternative mechanism for capturing the human demonstration data. A notable advantage of employing cameras lies in obviating the necessity for individuals to sensors, thereby offering a more expeditious and streamlined alternative to conventional data collection methods. In [3  ###reference_b3###], Cai et al. used a single camera to track the position of human-driven objects, facilitating the subsequent emulation of these trajectories by robotic systems.\nIn recent years, a proliferation of camera-based skeletal detection tools has emerged, among which OpenPose, introduced by Cao et al. in 2017 [4  ###reference_b4###]. It enables the real-time extraction of human skeletal structures from webcam feeds and is amenable to multi-person scenarios, although it demands relatively high hardware requirements. In [5  ###reference_b5###], Fang et al. localized whole-body keypoints accurately and tracked humans simultaneously with OpenPose. However, for fine tasks, it is insufficient to track the Cartesian coordinates of the human body; it also requires the orientation of parts of the human body, such as the hands. For example, in [6  ###reference_b6###], Li et al. extracted factors from hand heatmaps to estimate hand poses and teleoperate a dual-arm system. MediaPipe is another vision-based tool for human skeletal keypoint extraction [7  ###reference_b7###]. In comparison to OpenPose, MediaPipe holds the advantage of accurately and efficiently capturing two-dimensional (2D) key points of the human hand, thus facilitating precise hand gesture acquisition. In [8  ###reference_b8###], Chen et al. utilized two cameras to capture 2D points of the hand and generate the three-dimensional (3D) coordinates to obtain trajectories of the human hand.\n###figure_1### Subsequent to the reception of human-guided instructions, robots have to learn from human actions. Behavioral cloning is a method to duplicate the human behavior by collecting the demonstration data, and the input-output mapping is simply supervised by learning methods [9  ###reference_b9###]. In comparison to behavioral cloning, reinforcement learning (RL) offers a more flexible and adaptive approach to learning. In [10  ###reference_b10###], an inverse RL infers the latent reward function of a task from expert demonstrations to better understand the task structure and generalize to novel situations. While the inverse RL method requires a more substantial volume of data and computational resources, Dynamic Movement Primitives (DMP) emerges as a notable methodology for robotic motion generation and control with a single demonstration [11  ###reference_b11###]. DMP aims to simulate the dynamic properties and flexibility exhibited by human when performing motion. This enables the DMP to generate suitable motions when encountering new situations, and allows for fine-tuning and adaptation while following prescribed trajectories. In [12  ###reference_b12###], the integration of DMP with adaptive admittance control enables the path planning and force control on curved surfaces.\nSeveral works have integrated DMP with vision sensors to control the manipulator. In [13  ###reference_b13###], Chen et al. utilized You Only Look Once (YOLO) to train and detect hand shapes with two webcams, enabling the robot to pick up an object and place it in a human hand. DMP was applied to set trajectories of the end-effector, learned from dragging movements. Similarly, Cai et al. detected multiple hand demonstrations using a depth camera and OpenPose to obtain a comprehensive translational trajectory and predict the endpoint by DMP [14  ###reference_b14###]. However, these works did not explicitly consider the hand\u2019s quaternions in motion planning. To the best of the author\u2019s knowledge, there has been no application of DMP with both translational and rotational demonstrations captured by cameras. Incorporating quaternions in motion planning adds a layer of dexterity, and exploring this aspect could be a potential avenue for future research in enhancing manipulator control.\nThe proposed framework is shown as in Fig. 1  ###reference_###. In this paper, a depth camera is employed with MediaPipe applied in generating 2D images which are then combined with the depth data to capture the 3D coordinates of the whole human hand. This enables the recording of the trajectory, orientation, and grasping of its movements. To mitigate the impact of the inevitable minor tremors in human motion, the acquired human demonstration data undergoes a pre-processing phase with proposed method to calculate the orientation of the hand and finger motions, involving the application of a mean filter. Following pre-processing, a modified DMP is proposed to learn the coordinate trajectory of the wrist. The new trajectories with novel start and end points are applied to the execution of the pick-and-place task. This task entails the precise manipulation of objects, such as the experimental demonstration including picking up object at a specified angle, avoiding obstacles, and the ultimate placement of the object within an inclined receptacle. The proposed framework offers a novel effective approach to many dexterous manipulation tasks."

+    "title": "Collaborative Multi-source Domain Adaptation Through Optimal Transport",
+    "abstract": "Multi-source Domain Adaptation (MDA) seeks to adapt models trained on data from multiple labeled source domains to perform effectively on an unlabeled target domain data, assuming access to sources data. To address the challenges of model adaptation and data privacy, we introduce Collaborative MDA Through Optimal Transport (CMDA-OT), a novel framework consisting of two key phases. In the first phase, each source domain is independently adapted to the target domain using optimal transport methods. In the second phase, a centralized collaborative learning architecture is employed, which aggregates the N models from the N sources without accessing their data, thereby safeguarding privacy. During this process, the server leverages a small set of pseudo-labeled samples from the target domain, known as the target validation subset, to refine and guide the adaptation. This dual-phase approach not only improves model performance on the target domain but also addresses vital privacy challenges inherent in domain adaptation.",

+            "text": "Supervised learning is a cornerstone of machine learning, but it relies heavily on labeled data, which is often expensive and time-consuming to obtain. While transfer learning and generalization offer potential solutions, domain shift\u2014defined as the divergence between the probability distributions of two domains\u2014remains a significant challenge. Consequently, a model trained on labeled data from domain A (source) and tested on unlabeled data from domain B (target) typically suffers from performance degradation compared to being trained and tested within the same domain B, which is impractical without labels. To address these challenges, domain adaptation methods are employed. Within these approaches, some can manage adaptation between a single source and a single target, referred to as single-source domain adaptation (SDA) methods, while others handle adaptation between multiple sources and a single target, known as multi-source domain adaptation (MDA) methods.\nSeveral works have advanced MDA. For instance, [Mansour et al., 2021  ###reference_bx16###] provided a theoretical analysis based on the assumption that the target is a convex combination of source domains. [Zhao et al., 2019  ###reference_bx27###] proposed new error bounds for regression and classification tasks. Other research efforts focused on specific algorithms, such as combining diverse classifiers through novel weighting techniques [Zhao et al., 2020  ###reference_bx28###], or using domain transform frameworks to find latent domain spaces via clustering [Hoffman et al., 2012  ###reference_bx9###]. Generally, these studies estimate a mixed distribution or combine multiple single-source models.\nThe collaborative learning paradigm generally, and federated learning particularly, has garnered significant attention from both academia and industry. Initially introduced by [McMahan et al., 2017  ###reference_bx17###], this approach enables model training on data from various sources, such as mobile devices or organizations, without requiring centralized data access. This concept is pivotal for addressing data privacy concerns in domain adaptation, as it allows for the utilization of source domain data without direct access.\nUnsupervised domain adaptation methods based on optimal transport have recently gained traction due to their success in various machine learning problems [Laclau et al., 2017  ###reference_bx11###] [Ben-Bouazza et al., 2019  ###reference_bx2###] [Ben-Bouazza et al., 2022  ###reference_bx1###]. These methods are adept at discovering and learning the minimal transformation cost from source to target domains, effectively reducing domain discrepancies (i.e., domain shift).\nIn this context, we propose a novel approach that combines optimal transport with collaborative learning to enhance model performance on the target domain using multiple source domains. Our method, which we term Collaborative Multi-source Domain Adaptation through Optimal Transport (CMDA-OT), leverages the strengths of both frameworks to achieve superior adaptation while preserving data privacy.\nThe rest of this paper is structured as follows: Section 2 provides the necessary preliminary knowledge and notations for unsupervised multi-source domain adaptation and optimal transport theory. Section 3 presents our proposed approach for MDA, CMDA-OT. Section 4 demonstrates a comparative study with state-of-the-art methods on two benchmark datasets for MDA. Finally, Section 5 concludes the paper."

Both labeled data from the source domains and unlabeled data from the target domain are assumed to be accessible throughout the training phase [Redko et al., 2019  ###reference_bx22###].\nMore formally, for each source, we have access to a set  of  independent and identically distributed (i.i.d.) labeled samples of the  source pulled from the joint distribution , and a set  of  i.i.d. unlabeled target samples pulled from the marginal distribution  of the joint distribution  over :\nand \u2003.\nThe objective of unsupervised multi-source domain adaptation is to build a robust classifier  with a low target risk:\n,\nunder the assumption of domain shift not only between the source and target domains but also among the source domains themselves:\nand \u2003."

+            "text": "Collaborative learning enables the joint training of machine learning models through the collaboration of multiple parties (e.g., devices, organizations) without sharing local data. Federated learning (FL) is a specific instance of collaborative learning and is typically classified into either centralized or decentralized paradigms. Many contemporary FL systems support neural network training. Google proposed a scalable production system that allows the training of deep neural networks by hundreds of millions of devices [Bonawitz et al., 2019  ###reference_bx3###]. Centralized FL can be represented by a set of  models for  clients (i.e., data sources) and a server model that centralizes the learning process, as depicted in Figure 1  ###reference_###.\n\n###figure_1### The training process in centralized FL consists of four repetitive phases. Firstly, each client model is trained on its local private data. Secondly, each client sends its model (i.e., weights) to the server, following the FedAvg algorithm [McMahan et al., 2017  ###reference_bx17###]. Various algorithms, such as the FedSGD algorithm [McMahan et al., 2017  ###reference_bx17###], have been proposed to handle the exchange of information between models. The FedSGD algorithm allows for the transmission of gradients rather than weights, which is considered more effective but requires increased communication, potentially straining the distributed FL system. In the third phase, the server averages the received weights from the  clients. This average is weighted by the number of samples in each client\u2019s data, normalized by the sum of the counts of all samples across all clients, as proposed by Google [McMahan et al., 2017  ###reference_bx17###]. Finally, in the fourth phase, the clients receive the new weights and update their models.\nThe decentralized or Peer-to-Peer federated learning paradigm follows the same principles as centralized FL, except it does not require a trusted server to centralize the learning process. Figure 2  ###reference_### illustrates the overall repetitive process of training  client models.\n\n###figure_2### Initially, each client trains its model on its local private data. In the second and third phases, it requests the weights or gradients from other clients to update its model with both its local data and the received exchangeables (i.e., weights or gradients). Numerous algorithms have been proposed within this paradigm. For instance, BrainTorrent [Roy et al., 2019  ###reference_bx23###] is a selective algorithm where clients communicate and update their models using only the exchangeables from clients who have updates to send. This process continues until convergence. The order of operations is crucial in decentralized FL algorithms and significantly impacts the final training results. For example, the outcome may differ if client 1 uses the weights or gradients from client 2 before client 2 does. This challenge underscores the importance of the collaboration order. simFL [Li et al., 2020  ###reference_bx12###] is a decentralized approach to federated learning that adopts the centralized paradigm in a decentralized manner. This method involves selecting one client as the server in each iteration and treating the others as clients.

Initially,\nwe apply optimal transport, as the first part, to project each source domain data into the target domain space using the Sinkhorn algorithm with L1L2 class regularization. This process aims to find a new representation of the source domain data that closely resembles the representation of the target domain, thereby reducing the domain shift phenomenon between them. This new representation is referred to as the transported data of the source domain.\n\n###figure_3### Optimal transport generates new representations of the source domain data, which may not always be the most discriminative representation. In some cases, it could be inferior to the original representation of the source domain data, possibly due to factors such as data imbalance. To address this issue, we utilize a small set of pseudo-labeled data from the target domain, referred to as the target domain validation data, to assess the quality of the new representation. This involves testing and comparing the accuracy of models trained on both the transported and original data. If an improvement is observed when testing on the transported data, the client may opt to use this data for further steps of the adaptation. Otherwise, the original representation is retained as the preferred choice.\nThe subsequent part involves the intervention of centralized collaborative learning, federated learning as instance, with each client acting as a source domain. In our approach, we employ the FedAvg algorithm [McMahan et al., 2017  ###reference_bx17###] for the learning process. Here, each client sends its own weights after the local training step, and the server aggregates these weights, taking into account coefficients assigned to each client.\n[McMahan et al., 2017  ###reference_bx17###] defines the weight aggregation that takes place on the server as a weighted sum of all the clients\u2019 weights. The coefficient assigned to each client is directly proportional to the number of samples in that client. Formally:\nwith:\nWhile it is logical and sensible to weight the sum of the weights based on the number of samples provided by each client, this approach appears to work better in scenarios where all clients have the same probability distribution (i.e., the same domain). In Unsupervised Multi-source Domain Adaptation (UMDA), where different domains are involved, a client with fewer samples may contribute more effectively to improving the final model than another client with more data. Failing to account for this domain shift and weighting solely based on the number of samples can lead to less reliable results. To address this issue, we propose weighting all clients by defining coefficients that are directly proportional to the performance of each client model when tested on the small pseudo-labeled validation portion of target domain data. This test takes place in each client.\nOur proposition takes into account the paramount importance of privacy, which is a necessity across all industries today. It is often challenging to train a model without direct access to the data, particularly in the context of domain adaptation and phenomena such as domain shift, where data from multiple sources may be required to leverage information for building a robust model while still adhering to privacy regulations. To enhance domain adaptation within the constraints of privacy, we propose CMDA-OT. Table 1  ###reference_### highlights the advantages of CMDA-OT in comparison to relevant literature and related works.\n###table_1###"

In our scalable proposition, this validation proportion can be labeled by experts if available, which can lead to improved results. Alternatively, we propose a pseudo-labeling approach to handle fully unsupervised training for the target domain model. The HOT [El Hamri et al., 2022  ###reference_bx5###] approach offers a scalable solution that can be applied in our scenario. Initially, we cluster the target domain data on the server using one of the clustering algorithms proposed by the literature. In our experiments, we utilized spectral clustering, as it represents one of the state-of-the-art in clustering algorithms. Once the clusters are obtained and random labels are assigned, this pseudo-labeled validation data is distributed to each client. Here, we apply hierarchical optimal transport (HOT), which calculates the correspondence between each source domain labels and the random labels assigned to this data during clustering. Figure 4  ###reference_### illustrates an example of the HOT correspondence matrix.\n\n###figure_4### The results obtained from different clients are not always identical. Therefore, when there are three or more clients, we apply a majority vote to determine the outcome. In cases where there are only two clients, we use the correspondence of the source domain that is closest to the target domain, as determined by the Wasserstein distance."

+            "text": "The validation part of the target data serves as a guide for adaptation in both phases. During the optimal transport phase, this part determines whether accuracy improves when using the new representation obtained by the optimal transport transformation. If not, the original data representation is retained. This testing occurs across all clients, i.e., all sources. Each client receives this pseudo-labeled data and conducts an internal test to determine which representation, i.e., original or transported, to use in the next phase of adaptation, which is the collaborative learning.\nDuring the collaborative learning training phase, the server utilizes the target domain validation portion. Upon receiving the models weights from all clients, the server tests each client\u2019s model on this validation set and records their accuracies. This process is repeated for all client models. The accuracies are then normalized by their sum and used as coefficients for aggregating the incoming models weights. This approach ensures a highly dynamic adaptation, continuously adjusting the target model as each client\u2019s model evolves during the learning process. It also provides a robust metric for determining the importance of each source to the target domain.\nThe effectiveness of validation data pseudo-labeling is directly linked to the quality of clustering. Higher cluster purity results in more accurate label assignments. Therefore, we employed spectral clustering in our experiments. The HOT [El Hamri et al., 2022  ###reference_bx5###] method effectively maps random labels from clustering to real labels. This approach ensures that the training process remains entirely unsupervised for better fine-tuning the target model weights, while being flexible enough to replace the expert-labeled validation set. When clusters are pure, the pseudo labels closely match the actual labels.\nIn addition to preserving privacy, collaborative learning provides substantial benefits in scalability and flexibility. By sharing the weights of each source model, we overcome the limitations of individual models when aggregating them into a unified target model. This collaborative approach allows us to fully leverage the potential of data and knowledge without sharing or exposing the actual data or compromising privacy."

Instead, the federated server manages the learning process and has access to the target data.

Currently, the number of tests conducted is 1000.\n###table_2### ###table_3### The system includes some parameters that need to be tuned for optimal performance. One key parameter is the number of neighbors in spectral clustering, which needs adjustment to enhance clustering quality. Metrics like the Silhouette index or other internal indices can be used for this evaluation. The regularization parameters in optimal transport, whether Entropy-Regularization or Class-Regularization, must also be adjusted for each source (preferable) or uniformly across all sources. Certain regularization values may lead to mathematical issues, such as division by zero. For our experiments, we provide recommendations regarding the regularization values for each source to enhance the new representation obtained by optimal transport. These parameters can be adjusted locally in each source using pseudo-labeled validation data (test-driven approach). Generally, it is preferable to minimize Entropy-Regularization and maximize Class-Regularization without encountering mathematical errors. Minimizing Entropy-Regularization below a certain threshold or maximizing the gap between Entropy-Regularization and Class-Regularization may result in mathematical operational errors. These mathematical errors are inherent to the optimal transport algorithm and beyond our control.\nTo assess the performance of our approaches, we use the Friedman test and Nemenyi test as recommended in [Friedman, 1937  ###reference_bx6###] using the  package [Herbold, 2020  ###reference_bx8###]. The Friedman test is conducted to test the null hypothesis that all approaches are equivalent in terms of accuracy. If the null hypothesis is rejected, the Nemenyi test is performed. If the average ranks of two approaches differ by at least the critical difference (CD), their performances are significantly different. In the Friedman test, we set the significance level at .\nFigure 5  ###reference_### shows a critical diagram representing the projection of average ranks of approaches on an enumerated axis. The approaches are ordered from left (worst) to right (best), with a thick line connecting the approaches where the average ranks are not significantly different at a 5% significance level. As shown in Figure 6  ###reference_###, CMDA-OT achieves significant improvement over other proposed techniques, demonstrating stability during the federated learning phase. This process stops the collaboration for certain views when their local quality starts to decrease, preventing common issues in federated approaches. Compared to the most cited state-of-the-art approaches, the positive impact of using federated learning based on this theory is evident.\nThe statistical analysis was conducted for 7 approaches with 5 paired samples.\nThe family-wise significance level of the tests is alpha=0.050.\nWe rejected the null hypothesis that the population is normal for the approaches CMSD (p=0.000), DS (p=0.000), TCA+CMSD (p=0.000), TCA+WAF (p=0.000), TCA+WDS (p=0.000), TCA+WDSC (p=0.000), and CMDA-OT (p=0.000). Therefore, we assume that not all approaches are normal.\nBecause we have more than two approaches and some of them are not normal, we use the non-parametric Friedman test as omnibus test to determine if there are any significant differences between the median values of the approaches. We use the post-hoc Nemenyi test to infer which differences are significant.\n\n###figure_5### \n###figure_6### We report the median (MD), the median absolute deviation (MAD) and the mean rank (MR) among all approaches over the samples. Differences between approaches are significant, if the difference of the mean rank is greater than the critical distance CD=1.274 of the Nemenyi test.\nWe reject the null hypothesis (p=0.000) of the Friedman test that there is no difference in the central tendency of the approaches CMSD (MD=37.300+-2.025, MAD=2.340, MR=6.800), DS (MD=41.870+-1.400, MAD=2.350, MR=6.200), TCA+CMSD (MD=64.310+-4.195, MAD=7.620, MR=4.600), TCA+WAF (MD=64.600+-5.135, MAD=8.200, MR=4.000), TCA+WDS (MD=65.680+-3.060, MAD=5.970, MR=3.000), TCA+WDSC (MD=65.820+-2.645, MAD=4.060, MR=2.400), and CMDA-OT (MD=69.000+-3.125, MAD=4.250, MR=1.000). Therefore, we assume that there is a statistically significant difference between the median values of the approaches.\nBased on the post-hoc Nemenyi test, we assume that there are no significant differences within the following groups: CMSD and DS; TCA+CMSD and TCA+WAF; TCA+WAF and TCA+WDS; TCA+WDS and TCA+WDSC. All other differences are significant.\n###figure_7### ###figure_8### Sensitivity Box-Whiskers plots (figure 7  ###reference_###) represents a synthesis of the scores into five crucial pieces of information identifiable at a glance: position measurement, dispersion, asymmetry and length of Whiskers. The position measurement is characterised by the dividing line on the median (as well as the middle of the box). Dispersion is defined by the length of the Box-Whiskers (as well as the distance between the ends of the Whiskers and the gap). Asymmetry is defined as the deviation of the median line from the centre of the Box-Whiskers from the length of the box (as well as by the length of the upper Whiskers from the length of the lower Whiskers, and by the number of scores on each side). The length of the Whiskers is the distance between the ends of the Whiskers in relation to the length of the Box-Whiskers (and the number of scores specifically marked).\nThese graphs show the same overall performance behaviour observed in the case of VLSC and Office-Caltech10 datasets. They show a clear improvement as a result of the the proposed approach. This improvement is observed for all datasets used."

Existing methods are often constrained by limited receptive fields, resulting in sub-optimal performance when handling scenarios with large motion.

It has various real-life applications, such as creating slow motion videos [13  ###reference_b13###, 10  ###reference_b10###, 3  ###reference_b3###], video compression [12  ###reference_b12###, 33  ###reference_b33###] and novel view synthesis [1  ###reference_b1###, 7  ###reference_b7###, 38  ###reference_b38###].\nCurrently, flow-based algorithms occupy a prominent position [37  ###reference_b37###, 9  ###reference_b9###, 26  ###reference_b26###, 28  ###reference_b28###, 17  ###reference_b17###, 18  ###reference_b18###, 30  ###reference_b30###] in VFI task, where the flow from the target frame to the input frames, namely, intermediate flow, is explicitly estimated for warping input frames to the target frame.\nNevertheless, existing optical flow [32  ###reference_b32###, 34  ###reference_b34###, 11  ###reference_b11###] algorithms cannot be directly applied to estimate intermediate flows due to the absence of the target frame.\nTo address this, many algorithms first estimate the bidirectional flow between two input frames and then generate intermediate optical flows using various flow reversal techniques [35  ###reference_b35###, 19  ###reference_b19###, 13  ###reference_b13###, 29  ###reference_b29###, 24  ###reference_b24###, 39  ###reference_b39###, 15  ###reference_b15###].\nAlternatively, recent algorithms directly estimate the intermediate flow with proper supervision [17  ###reference_b17###, 37  ###reference_b37###, 9  ###reference_b9###] and achieve improved performance on datasets where small-to-medium motions are prevalent [27  ###reference_b27###].\nHowever, real-world video frame interpolation encounters various complex challenges, with the problem of handling large motion being particularly prominent.\nIn scenarios characterized by large motion, the correspondence of objects between frames is hard to locate due to the large pixel shifting.\nMany works have been proposed to alleviate this problem. For example, XVFI [29  ###reference_b29###] addressed this by creating an extreme 4K training dataset and a scalable framework. However, its performance improvement is limited when applied to small motion scenarios [25  ###reference_b25###]. FILM [27  ###reference_b27###] introduced scale-agnostic features and a weight-sharing approach to improve model generalization across different motion scales. In fact, due to its limited receptive field, the model\u2019s depth can become excessively deep when dealing with large motion. This increases computational complexity and falls short in handling fast-moving small objects.\nIn this paper, we introduce a sparse global matching pipeline to specifically handle the challenges posed by large motion in the VFI task, by effectively integrating global-level information into intermediate flow estimation.\nOur VFI method establishes sparse global correspondences between input frames using a global receptive field and takes a two-step strategy to compensate for the intermediate flow estimation.\nSpecifically, as shown in Figure 1  ###reference_### (a - b), our method begins with an initial estimation of a pair of intermediate flows using a relatively high-resolution feature map. Following this initial estimation, our approach incorporates a sparse global matching branch to locate potential error in the flow estimation results, and then produce flow residual to provide an effective remedy for capturing large motion.\nTo be specific, in our sparse global matching branch, we build a difference map to pinpoint the flaws in initial intermediate flow estimations. Concentrating on these defective areas, our approach employs sparse global matching to establish global correspondences between two adjacent input frames, specifically at these sparsely targeted locations. Subsequently, we convert this bidirectional sparse flow correspondence into intermediate flow compensation. Finally, we employ a flow merging block to adaptively merge the initial intermediate flows and flow compensation, thereby effectively combining the local details with the global correlation. As shown in Figure 1  ###reference_### (c), our sparse global matching branch can effectively locate the error regions and rectify the flaws in the initial intermediate flow estimation, yielding a significantly enhanced synthesized intermediate frame.\nIn order to benchmark the effectiveness of our sparse global matching module on handling large motion, we carefully analyze motion magnitude and sufficiency within existing benchmarks, X-Test [29  ###reference_b29###], Xiph [22  ###reference_b22###] and SNU-FILM [4  ###reference_b4###]. In our analysis, we utilize the motion sufficiency filtering method described in [1  ###reference_b1###], emphasizing the minimum of the top 5% of each pixel\u2019s flow magnitude as the key indicator of large motion sufficiency. In the end, we carefully curate the most challenging subsets for large motion frame interpolation evaluation. In the most challenging testing conditions, our proposed method demonstrates a substantial improvement in terms of PSNR, enhancing it by  dB while correcting half of the points in initial flow estimation. Furthermore, even with the correction of just  points, we still observe a notable increase of  dB. Notably, our approach establishes a new state-of-the-art performance benchmark in these exceptionally challenging scenarios. In summary, our main contributions include:\nWe introduce a sparse global matching algorithm tailored to effectively capture large motion.\nWe designed an effective two-step framework for capturing large motion. First, by estimating initial intermediate flows to extract the local details, then targets and corrects the detected flaws through sparse global matching at sparsely targeted defective points.\nOur models demonstrate state-of-the-art performance on the most challenging subset of the commonly used large motion benchmark, namely, X-Test-L, Xiph-L, SNU-FILM-L hard and extreme."

These flows enable the model to either forward warp or backward warp the input frames to the target frame. Some algorithms first compute bidirectional flows between two input frames and apply different flow reversal techniques to obtain intermediate flows [24  ###reference_b24###, 35  ###reference_b35###, 29  ###reference_b29###], while the others directly estimate intermediate flows [9  ###reference_b9###, 37  ###reference_b37###, 17  ###reference_b17###].\nHowever, flow reversal techniques may introduce artifacts to intermediate flows, which can harm the details of the intermediate flows, causing misalignment [13  ###reference_b13###] or holes [35  ###reference_b35###]. Direct estimation of intermediate flows is also restricted by the model design, usually has a limited perceptive field [9  ###reference_b9###, 37  ###reference_b37###], and lacks robustness on large motion.\nAddressing the issue of large motion in video frame interpolation, FILM [27  ###reference_b27###] adopts a coarse-to-fine approach and shares weights between layers. It also trains on data with varied motion magnitudes, enabling it to learn to handle large motions. AMT [18  ###reference_b18###] uses the RAFT-like structure to construct an all-pair correlation map and locally refines the intermediate flow afterward. BiFormer [26  ###reference_b26###] employs a global feature extractor to extract global features and build local bilateral correlation maps. However, due to the high resolution of the VFI task, giving the model a genuine global receptive field is challenging.\nIn contrast, our work uses local features to estimate the intermediate flows and global features to sparsely generate bidirectional flow compensation by global matching. We then adaptively merge the flows and flow compensation to obtain the final intermediate flow with both global information and local details."

BiFormer [26  ###reference_b26###] adopts pretrained Twins architecture [5  ###reference_b5###] for global feature extraction and builds local bilateral correlation cost volume. However, when handling large motion, these methods are more or less restricted by their local receptive field.

This approach still demonstrated noticeable effects attributed to the global matching process. However, as indicated in Table H12  ###reference_###, the ability to capture large motion was not on par with the results obtained after finetuning on a dataset with larger motion. Therefore, finetuning on a small batch of large motion datasets (X-Train) is more efficient than training from scratch on a large batch of small motion datasets (Vimeo-90K). This efficiency is evidenced by the reduced number of required training steps, with finetuning necessitating only 13.7k steps as opposed to 480k steps for training from scratch. This finding aligns with the observations reported in FILM [27  ###reference_b27###], suggesting that large motion datasets can bring large motion capturing ability."

+    "abstract": "This paper lays a practical foundation for using abstract interpretation with an abstract domain that consists of sets of quantified first-order logic formulas. This abstract domain seems infeasible at first sight due to the complexity of the formulas involved and the enormous size of sets of formulas (abstract elements). We introduce an efficient representation of abstract elements, which eliminates redundancies based on a novel syntactic subsumption relation that under-approximates semantic entailment. We develop algorithms and data structures to efficiently compute the join of an abstract element with the abstraction of a concrete state, operating on the representation of abstract elements.\nTo demonstrate feasibility of the domain, we use our data structures and algorithms to implement a symbolic abstraction algorithm that computes the least fixpoint of the best abstract transformer of a transition system, which corresponds to the strongest inductive invariant.\nWe succeed at finding, for example, the least fixpoint for Paxos (which in our representation has 1,438 formulas with  quantification) in time comparable to state-of-the-art property-directed approaches.",

However, an abstract domain of quantified first-order formulas seems infeasible: for interesting systems, the abstract elements involved in proofs would contain an astronomical number of formulas.\nThe main contribution of this work is to develop algorithms and data structures that\nmake an abstract domain based on quantified first-order formulas feasible.\nWorking with this abstract domain introduces two main challenges:\n(i) efficiently storing and manipulating abstract elements comprising of many formulas,\nand (ii) overcoming solver limitations when reasoning over them.\nThis work focuses on the first challenge and adopts ideas from prior work [14  ###reference_b14###] to deal with the second.\nOur techniques lay a practical foundation for using an abstract interpretation approach to develop new analyses in the domain of quantified first-order formulas.\nWe demonstrate feasibility of the abstract domain by applying it to an analysis of several intricate distributed protocols.\nOur first key idea is to design a subsumption relation for quantified first-order formulas and use it to\nrepresent abstract elements (sets of formulas) more compactly, pruning away some formulas that are redundant since they are\nequivalent to or are entailed by another formula.\nSubsumption over propositional clauses (disjunctions of literals) is traditionally used for similar pruning purposes\n(e.g., [18  ###reference_b18###]),\nbut the generalization to first-order formulas, which include disjunction, conjunction, and quantification, is novel.\nThe second key ingredient of our approach is a way to manipulate abstract elements in our representation.\nRather than implementing the standard operations of  (abstraction) and  (abstract join),\nwe observe that our subsumption-based representation makes it more natural to directly implement\nan operation that computes the join of an abstract element  with the abstraction of a given concrete state , i.e., .\nThis operation can be used to compute the abstraction of a set of states,\nand can also be used to compute the least fixpoint of the best abstract transformer (in the style of symbolic abstraction [26  ###reference_b26###]).\nThe crux of computing  is to weaken the formulas in the representation of  to formulas that are subsumed by them and that  satisfies.\nFinally, the third key ingredient of our approach is a data structure for storing a set of formulas,\nwith efficient filters for (i) formulas that a given state does not satisfy, and (ii) formulas that subsume a given formula. This data structure is then used to store abstract elements, and the filters make the implementation of  more efficient.\nWhile the paper presents the ingredients of our approach (subsumption, weakening, and the data structure) sequentially, they are interconnected; they all affect each other in subtle ways, and must be designed and understood together.\nSpecifically, there is an intricate tradeoff between the precision of subsumption, which determines the extent of pruning (and therefore the compactness of the representation), and the complexity of abstract domain operations such as weakening\n(e.g., for computing ).\nThe definitions, algorithms, and data structures we present are carefully crafted to balance these considerations.\nOur subsumption relation, which approximates entailment, is cheap to compute, eliminates enough redundancy to keep the representation of\nabstract elements compact, and enables an efficient implementation of the weakening operation.\nTo evaluate our implementation of the abstract domain, we use it to implement a symbolic abstraction [26  ###reference_b26###] procedure that computes the least fixpoint of the best abstract transformer of a transition system (i.e., the strongest inductive invariant for the transition system in the given language).\nOur evaluation uses benchmarks from the literature, mostly from safety verification of distributed protocols.\nWhile our fixpoint computation algorithm is not fully competitive with property-directed invariant inference approaches that exploit various sophisticated heuristics and optimizations,\nit does demonstrate that fixpoint computation in our abstract domain is feasible,\nwhich is quite surprising given the amount of quantified formulas the domain considers.\nOur approach successfully\ncomputes the least fixpoint\nfor transition systems that previously could only be analyzed using property-directed, heuristic techniques (which do not compute the least fixpoint, but an unpredictable heuristic fixpoint).\nFor example, we succeed at finding the strongest inductive invariant of Paxos as modeled in [23  ###reference_b23###] (which in our representation has 1,438 formulas with  quantification, representing orders of magnitude more subsumed formulas).\nIn summary, this paper makes the following contributions:\nWe develop\na compact representation of sets of formulas based on a novel syntactic subsumption relation. We make a tradeoff here between the extent of pruning and efficiency, accepting some redundant formulas in exchange for practical algorithms. (Sec. 3  ###reference_###)\nWe show how to implement a key operation of weakening a formula to be satisfied by a given state,\nand leverage it to compute the join of an abstract element and the abstraction of a state, when abstract elements are represented using our subsumption-based representation.\n(Sec. 4  ###reference_###)\nWe present a data structure that provides an efficient implementation of operations used in the join computation described above.\n(Sec. 5  ###reference_###)\nWe evaluate the approach by applying it to compute the least fixpoint of the best abstract transformer for several distributed and concurrent protocols from the literature, demonstrating the promise of our approach.\n(Sec. 6  ###reference_###)\nThe rest of this paper is organized as follows:\nSec. 2  ###reference_### introduces definitions and notation, Secs. 3  ###reference_###, 4  ###reference_###, 5  ###reference_### and 6  ###reference_### present the main contributions outlined above,\nSec. 7  ###reference_### discusses related work,\nand Sec. 8  ###reference_### concludes.\nThe proofs of all theorems stated in the paper are given\nin App. 0.B  ###reference_###.

This is clearly infeasible for complex languages such as the ones used in our benchmarks (see Table 1  ###reference_###), and is exacerbated by the fact that merely checking entailment is expensive for formulas with quantifiers. Instead, our key idea is to remove redundancies based on a cheap-to-compute subsumption relation, which approximates semantic entailment, and enables efficient operations over abstract elements such as joining them with an abstraction of a concrete state.\nWe start the section with an inductive definition of a family of finite first-order languages that underlies all of our developments (Sec. 3.1  ###reference_###).\nWe then introduce a syntactic subsumption relation for first-order formulas (Sec. 3.2  ###reference_###), which we\nleverage to develop an efficient\ncanonicalization of formulas, effectively determining a single representative formula for each subsumption-equivalence class (Sec. 3.3  ###reference_###).

In fact, this is the first work to compute least fixpoints for any Paxos variant or cache. (DuoAI, for instance, has a component that attempts to compute a precise fixpoint, but [29  ###reference_b29###] reports that it times out on all Paxos variants.)\nUnsurprisingly, there is a significant gap between the runtimes of examples with and without quantifier alternation, mostly due to the time spent in SMT solvers. For example, in ticket we spend about  of the runtime performing weakenings, but this percentage drops to  and  for paxos-epr and flexible-paxos-epr, respectively. This causes the runtime of paxos-epr to exceed that of ticket by more than an order of magnitude, although its fixpoint computation considers fewer formulas and actually spends less time weakening.\nSimilarly, in cache we manage to prove a fixpoint of a hundred thousand formulas in about an hour and spend a third of it weakening formulas, while multi-paxos-epr and fast-paxos-epr time out, although they consider far fewer formulas and spend a negligible amount of time weakening.\nNext, we observe that the use of LSet significantly reduces time spent in weakening, leading to more than an order of magnitude difference even in moderate examples, e.g., ticket and paxos-epr. In terms of the total fixpoint computation time, in examples where the runtime is small or dominated by the SMT solvers, the effect might be negligible, but otherwise the speedup is significant. For example, cache is not solved within the 3-hour limit with a naive data structure; it gets stuck after reaching  20,000 formulas in the abstraction, whereas using LSet it is solved in about an hour while handling more than ten times the number of formulas. Similarly, in the two unsolved examples where SMT calls seem to be the bottleneck (multi-paxos-epr and fast-paxos-epr), using a naive data structure causes weakening to become the bottleneck and time out.\nFinally, the remaining timeouts, learning-switch, stoppable-paxos-epr, and vertical-paxos-epr, are the only examples where the weakening process itself is the bottleneck. These are cases where the language induced by the human-written invariant, using the constraining parameters of bounded languages, create a inefficient weakening process. The cause for this is either a profusion of literals in the basis language ( 600 in learning-switch and stoppable-paxos-epr, less than 200 in all other examples), or a very expressive language (e.g., vertical-paxos-epr uses 3-pDNF, whereas all other examples use 1- and 2-pDNF). For these examples, it might be necessary to restrict the languages in additional ways, e.g., as was done in [29  ###reference_b29###].\nOur experience, however, is that the more significant bottleneck for computing least fixpoints for the most complicated examples is the SMT queries."

On the other hand, this makes filtering for subsets in UBTrees and LSets more efficient. Also note that LSet is more general than both, since it supports a more general subsumption relation."

This is not entirely surprising, since in this case, permuting the variables and permuting the literals in the disjunction has the same effect.\nAs an example, let us weaken the bottom element  for , i.e., , with the state  where , , and  is an arbitrary assignment. At the topmost level, the weakening procedure for , detailed in Thm. 4.1  ###reference_theorem1###, requires us to first compute\nwhere , and  are all updates of  with assignments to . The above can be computed iteratively as follows:\n;\n;\n\n.\nIn our case , and all updated states satisfy  and . Therefore, , and no formula is weakened further, since both formulas in  are satisfied by the remaining . Thus, . As expected, at the end of this process we are guaranteed to get formulas satisfying all possible updates of  with assignments to .\nAs we saw in Sec. 0.A.3  ###reference_.SS3###, both of the resulting formulas are canonical; however, adding the requisite quantification results in one non-canonical formula. This demonstrates the need for additional canonicalization for .\nNote the savings the subsumption-based representation affords us even for this simple language. The singleton , which we effectively weakened per Alg. 1  ###reference_thm1###, represents the following abstract element containing 21 formulas:\nMoreover, the singleton  we got from the weakening process represents the following abstract element containing 14 formulas:\nbut throughout the weakening process we only dealt with at most two formulas."

For both disjunction cases, if each disjunct of  has a disjunct of  that it subsumes, and therefore entails, then any state satisfying , which therefore satisfies one of its disjuncts, also satisfies some disjunct of . For both conjunction cases, if each conjunct of  has a conjunct of  that subsumes it, and therefore entails it, than any state satisfying , which therefore satisfies all of its conjuncts, must also satisfy all of the conjuncts of . These conditions for disjunction and conjunction, respectively, are ensured by the respective subsumption relations. For the case of quantifiers, adding the same quantification to any  and , or quantifying  universally and  existentially, as well as permuting quantified variables, all maintain entailment, so the semantic property of subsumption can be directly lifted from the induction hypothesis.\nNext, we prove by induction that  is a preorder for all ; i.e., that it is reflexive and transitive. For the base case of  the claim clearly holds. For  where ,  is the standard preorder resulting from pointwise extension, which maintains reflexivity and transitivity. For , reflexivity is shown by choosing the mapping  and using the reflexivity of  (i.h.); regarding transitivity, given , there exist injective  and , so  is injective and guarantees , and using the transitivity of  (i.h.), . The cases of  and  for  are proven in a similar manner, by choosing the identity mapping or permutation, respectively, to show reflexivity, and composing mappings or permutations to show transitivity. For , the subsumption relation extends the subsumption relations of  for , and reflexivity and transitivity can easily be lifted from them.\nLastly, the fact that  for any  easily follows from its definition, using a similar inductive argument over the structure of bounded languages.\nThe proof follows the mutually inductive definitions of the canonicalization and the total order in Def. 3  ###reference_inition3###.\nTo avoid confusion, we write , , and  to refer to the canonicalization and orders of the language for which the claim is proven in the induction step (omitting the subscript).\nThe fact that  is representative, i.e., that  for all , is apparent in almost all cases, since they simply canonicalize subformulas in ways which, given the induction hypothesis, clearly result in subsumption-equivalent formulas.\nThe only interesting case is , where\nsince there might be fewer formulas in  than in , due to minimization, and the mappings from  to  and from  to  necessary to show mutual subsumption are not obvious. However, due to  being representative and decisive (i.h.), any formula in  has a formula subsuming it in ; and any formula in  has a subsumption-equivalent formula in . These facts precisely prove the existence of the required mappings.\nFor the decisiveness of , we need to show that . We begin with the \u201c\u201d direction. This is again straightforward in all cases aside from . For this case, denote  and , and assume . Every formula in  has a formula in  subsuming it, which is therefore also in , and has a subsumption-equivalent formula in . Thus, there is a mapping  showing , and the existence of a mapping for the other direction is symmetrical.\nNext, we recognize that the \u201c\u201d direction of decisiveness for  is implied by its representativeness together with  being a partial order (i.e., an anti-symmetric preorder) over canonical formulas, since then\nWe have already dealt with  being representative, and  being a partial order is implied by  being a total order over canonical formulas that extends , which we also need to prove. Therefore, it suffices to prove the last claim.\nThe fact that  is a total order can easily proven by observing that the inductive definitions either lift total orders in pointwise manners (, , , ), in lexicographic manners (, ), or by chaining them (). Showing that  extends  is more subtle. In the base case this holds by definition. For  where , given canonical  it holds that  and , and therefore (i.h.)  and , which implies .\nFor , given canonical , there exists an injective  such that for all , , and thus . Since  and  are canonical, they are ordered by . Consider the following cases:\nThere exists  such that . Let this  be minimal.\nBy definition of the total order for ,  if .\nAssume for the sake of contradiction that  (we already know they are not equal). Observe that every  must have , since otherwise , contradicting . But this is a contradiction, since it means  is not injective. Thus, .\nOtherwise,  is a suffix of . ( cannot be longer than , since there is an injection from  to .) This case also implies .\nFor , given canonical , there exists  such that for all , , and thus . Since  and  are canonical, they are antichains w.r.t  ordered by . Consider the following cases:\nThere exists  such that .

Thus, either , which means that  and  is not canonical; or , which means that  and  is not canonical.\nTherefore, .\nOtherwise,  is a prefix of . ( cannot be a strict prefix of , since then there would be an element in , which is also in , subsuming two distinct elements in , making  non-canonical.) This case also implies .\nFor  where , given canonical , there exists  such that . Since  is -canonical,\nand since  is -canonical,  and therefore  as well. The case for  uses the two single-quantifier cases in a straightforward way.\nLet  and  its representation. Using the definition of , and due to  being antisymmetric and well-founded over canonical formulas, for all  there exists  such that .

Next, by definition, any  has some  such that , and therefore  and . This implies  and .\nTaken together, we conclude that  and .\nIn order to prove that the implementation in Thm. 4.1  ###reference_theorem1### satisfies the specification in Def. 5  ###reference_inition5###, it suffices to show that for all  and ,\n\n\n(i) is an antichain w.r.t  of canonical formulas,\n\n(ii) all formulas in  are subsumed by  and satisfied by , and\n\n(iii) for all  with  and , there exists  such that .\nThe above suffices for the proof since item (ii) shows that\nitem (iii) shows that\nand because item (i) tells us  is an antichain of canonical formulas,\nAs usual, we shall prove (i)\u2013(iii)\nby induction on the recursive implementation. These clearly hold for any case where , where the implementation always returns . We therefore restrict our discussion to cases where .\nClaim (i) can be easily verified by going case by case and using claim (i) of the induction hypothesis.\nClaim (ii) is likewise easy to prove using claim (ii) of the induction hypothesis, together with the definition of subsumption (Def. 2  ###reference_inition2###), and the fact that a disjunction is satisfied if one of its disjuncts is satisfied, a conjunction is satsified if all of its conjuncts are satisfied, an existentially quantified formula is satisfied if there exists a state updated with an assignment to quantified variables which satisfies its body, and a universally quantified formula is satisfied if all such updated states satisfy its body.\nThus, it remains to inductively prove claim (iii), which we do case by case. Keep in mind that we assume .\nFor , if ,  contains all  with , so (iii) holds due to reflexivity of .

Therefore,  must be strictly shorter than , and therefore . Note that this is only the case because we required  to be injective when defining the subsumption relation. This is crucial for weakening disjunctions in this way. Since  and , there exists some  such that  (i.h.), and\nand , (specifically, ; see Thm. 4.1  ###reference_theorem1###).\nFor , assume  and .

Similarly, to get all formulas subsuming , both disjuncts need to be subsumed; therefore,\n is used to get all first-position disjuncts that subsume , and for each  of them  is used to get the relevant second-position disjuncts subsuming .\nNote that  may not be an antichain, even if  is. For example, if  with  but , then  is an antichain but  (which holds ) is not.\nThe implementation for\n is similar to the binary disjunction case for , since the subsumption relation is defined identically. However,  requires only one of the conjuncts to be unsatisfied by . We therefore hold two set-map pairs as above: ,  and , . All first-position conjuncts that do not satisfy  can be retrieved using , and collecting for each such  all  where  results exactly in all formulas in the set where the first conjunct is not satisfied by . In a symmetrical manner we find all formulas in the set where the second conjunct is not satisfied by . As mentioned above, the  filter is implemented identically to the  case using , .\nThe case of  generalizes the case of , in the sense that all disjuncts need to be unsatisfied by  in ; and all disjuncts need to subsume a (distinct) disjunct in . Therefore, these operations are implemented by computing them for all disjuncts iteratively.\nWe use a tree structure whose edges are labeled with -formulas, and whose paths are understood as the sequences of disjuncts as they appear in formulas .\nSince we consider canonical formulas, we are ensured that disjuncts are ordered according to  along paths in the tree.\nEach node in the tree has an  that stores the -formulas labeling its outgoing edges, which represent the next possible disjuncts in the sequence of -formulas from the root to the node. This generalizes the  field in the binary case, which maintains the possible first-position disjuncts, i.e., the next disjuncts w.r.t the empty sequence.\nUsing this construction,  and  are implemented by tree traversals, with recursive applications of  and  for the sets  in the nodes, which are used to retrieve the next possible disjuncts not satified by , or the next possible disjuncts subsuming some disjunct in , respectively.\nIn the case of , since each resulting disjunct needs to subsume a distinct formula in , we remove  from  during the recursive traversal\nif it caused us to go down that edge.\nAs an optimization, when going down an edge labeled , we also remove from  all formulas , since such formulas cannot be subsumed by formulas greater or equal to .\nThe case of  is simpler. In addition to the standard , we maintain a field  aggregating all conjuncts from all formulas in . The formulas  which are not satisfied by  are those with some conjunct in ; and the formulas  subsuming  are those where for all  there is a conjunct of  in .\nThese checks are implemented in a straightforward way. An alternative approach is to store conjunctions in a tree structure similar to the LSet implementation for , and perform  and  using appropriate traversals of the tree (analoguously to the way UBTrees [11  ###reference_b11###] are used for finding both subsets and supersets). However, observe that the savings in the  case would be much more modest. For example, the implementation of  for  uses a recursive traversal of the tree that prunes away subtrees if the formula leading to them is satisfied by  (since any disjunction containing that formula is satisfied by ). For , discarding these paths is not possible, since it suffices for some conjunct to be violated by  for the entire conjunction to be unsatisfied by it. Thus,  would require recursively traversing the entire tree, and our experience is that the overhead of maintaining the tree structure makes this approach inefficient overall. We note, however, that the implementation of LSet for unbounded conjunction is the least optimized component of our approach, and might be improved further in future work.\nThe cases of  for  are each implemented using an LSet  over  to store the bodies of formulas, which is used to perform  and  by iterating over all assignments to the variables, or over all permutations of variables, respectively, and using the corresponding operations for . The case of  then uses these two data structures in a straightforward way.\nTable 2  ###reference_.T2### explained above relies heavily on maps that use formulas as keys. However, computing hashes of formulas can be expensive, and therefore an efficient implementation of  requires an additional optimization. Rather than using formulas as keys, in our implementation each  maintains a bidirectional mapping between formulas and integer IDs, and uses the IDs whenever possible, converting back to formulas only when producing the externally-facing output. For example, the filters applied to  in the implementation of  return a set of IDs that are then used as keys for , avoiding unnecessary hash computations. (Other approaches, such as memoization of hashes or hash consing, can alternatively be used.)"

Note, however, that this decomposition may replace one -pDNF formula with -pDNF formulas that have extra literals in their -pDNF clause, so this restriction may be a tradeoff between the parameter  and the size of the base language for the cubes.\nHowever, we find that in practice, using this restriction captures the languages necessary to prove safety much more precisely.\nThe proof for Lemma 1  ###reference_ma1### is presented below.\nWe prove an equivalent second-order formulation of the claim, where existentially quantified variables in  are replaced by existential quantification over fresh function variables , similarly to the process of Skolemization:\nSpecifically,  consists of the universally quantified variables in , and for all ,  replaces the -th existentially quantified variable in , where  are all the universally quantified variables in  preceding that existentially quantified variable in the quantifier prefix.\nTo simplify the notation we denote these function applications by , even though each of them may only depend on some of the variables in  (but note that all of them are dependent on ).\nUsing distributivity, the left-hand side of the above is equivalent to\nwhich entails the right-hand side of the claim, since if there exists an assignment to  satisfying both conjuncts, for each of the conjuncts there exists an assignment satisfying it.\nIt is left to show entailment in the other direction.

We propose Adjacent Leader Decentralized Gradient Descent (AL-DSGD), for improving final model performance, accelerating convergence, and reducing the communication overhead of decentralized deep learning optimizers. AL-DSGD relies on two main ideas. Firstly, to increase the influence of\nthe strongest learners on the learning system it assigns weights to different neighbor workers according to both their performance and the degree when averaging among them, and it applies a corrective force on the workers dictated by both the currently best-performing neighbor and the neighbor with the maximal degree.\nSecondly, to alleviate the problem of the deterioration of the convergence speed and performance of the nodes with lower degrees, AL-DSGD relies on dynamic communication graphs, which effectively allows the workers to communicate with more nodes while keeping the degrees of the nodes low.\nExperiments demonstrate that AL-DSGD accelerates the convergence of the decentralized state-of-the-art techniques\nand improves their test performance especially in the communication constrained environments. We also theoretically prove the convergence of the proposed scheme.\nFinally, we release to the community a highly general and concise PyTorch-based library for distributed training of deep learning models that supports easy implementation of any distributed deep learning approach ((a)synchronous, (de)centralized).",

+            "text": "Stochastic gradient descent (SGD) is the skeleton of most state-of-the-art (SOTA) machine learning algorithms. The stability and convergence rate of classical SGD, which runs serially at a single node, has been well studied [11  ###reference_b11###, 16  ###reference_b16###]. However, recently, the dramatical increase in the size of deep learning models [13  ###reference_b13###, 5  ###reference_b5###, 34  ###reference_b34###, 48  ###reference_b48###], the amount of computations and the size of the data sets [12  ###reference_b12###, 24  ###reference_b24###] make it challenging to train the model on a single machine. To efficiently process these quantities of data with deep learning models, distributed SGD, which parallelizes training across multiple workers, has been successfully employed. However, centralized distributed SGD with a parameter server [9  ###reference_b9###, 26  ###reference_b26###, 8  ###reference_b8###, 15  ###reference_b15###, 10  ###reference_b10###] suffers from the communication bottleneck problem when the framework either has a large number of workers or low network bandwidth [30  ###reference_b30###, 29  ###reference_b29###, 28  ###reference_b28###, 39  ###reference_b39###].\nTo overcome the communication bottleneck, decentralized frameworks have been proposed. Moving from centralized to decentralized learning system is a highly non-trivial task. Many popular distributed deep learning schemes, including EASGD [50  ###reference_b50###], LSGD [37  ###reference_b37###], as well as PyTorch embedded scheme called DataParallel [27  ###reference_b27###] are only compatible with the centralized framework. In a decentralized setting, there exists no notion of the central parameter server and the communication between workers is done over the communication network with a certain topology. The decentralized approach is frequently employed and beneficial for training in various settings, including sensor networks, multi-agent systems, and federated learning on edge devices. Most of the decentralized SGD algorithms communicate over the network with pre-defined topology and utilize parameter averaging instead of gradient updates during the communication step. This is the case for the SOTA approach called decentralized parallel SGD (D-PSGD) [28  ###reference_b28###], that allows each worker to send a copy of its model to its adjacent workers at every iteration, and its variants [28  ###reference_b28###, 29  ###reference_b29###, 42  ###reference_b42###, 22  ###reference_b22###]. These methods satisfy convergence guarantees in terms of iterations or communication rounds [14  ###reference_b14###, 20  ###reference_b20###, 32  ###reference_b32###, 35  ###reference_b35###, 38  ###reference_b38###, 45  ###reference_b45###, 49  ###reference_b49###, 28  ###reference_b28###, 29  ###reference_b29###]. Since each worker only needs to compute an average with its neighbors, they reduce communication complexity compared to centralized methods [29  ###reference_b29###, 4  ###reference_b4###, 21  ###reference_b21###, 28  ###reference_b28###, 42  ###reference_b42###]. (Neighbor workers refer to a group of workers within the distributed deep learning framework that are connected to a given worker.) Computing simple average of model parameters during the communication step effectively leads to treating all the workers over which the average is computed equally, regardless of their learning capabilities. What is new in this paper? In this paper, we propose AL-DSGD, a decentralized distributed SGD algorithm with a novel averaging strategy that assigns specific weights to different neighbor learners based on both their performance and degree, and applies a corrective force dictated by both the currently best-performing and the highest degree neighbor when training to accelerate the convergence and improve the generalization performance.\nFurthermore, the convergence rate of decentralized SGD is influenced by the network topology. A dense topology demands more communication time [42  ###reference_b42###], despite converging fast iteration-wise [42  ###reference_b42###, 22  ###reference_b22###], while a sparse topology or one with imbalanced degrees across learners (i.e., nodes have degrees that vary a lot; we will refer to this topology as imbalanced topology) results in a slower convergence in terms of iterations but incurs less communication delays [40  ###reference_b40###]. Previously proposed solutions addressing the problem of accelerating convergence without sacrificing the performance of the system include bias-correction techniques [46  ###reference_b46###, 19  ###reference_b19###, 47  ###reference_b47###, 36  ###reference_b36###, 18  ###reference_b18###, 47  ###reference_b47###, 1  ###reference_b1###], periodic global averaging or multiple partial averaging methods for reducing frequent communication [6  ###reference_b6###, 2  ###reference_b2###, 41  ###reference_b41###, 3  ###reference_b3###, 23  ###reference_b23###], methods that design new topologies [33  ###reference_b33###, 7  ###reference_b7###, 22  ###reference_b22###], or techniques utilizing the idea of communicating more frequently over connectivity-critical links and at the same time using other links less frequently as is done in the SOTA algorithm called MATCHA [42  ###reference_b42###, 39  ###reference_b39###]. However, these proposed solutions rely on simple model averaging or gradient summation during the communication step. Moreover, many of these solutions use an optimizer that is dedicated to single GPU training and naively adapt it to distributed optimization. It still remains a challenge to design a strategy for handling the communication topology that at the same time allows for fast convergence in terms of iterations and carries low communication burden resulting in time-wise inexpensive iterations. What else is new in this paper? Our proposed AL-DSGD algorithm addresses this challenge by employing dynamic communication graphs. The dynamic graphs are a composite structure formed from a series of communication graphs. The communication graph and weight matrices follow established practices[40  ###reference_b40###, 28  ###reference_b28###]. Each matrix W(k) is symmetric and doubly stochastic, ensuring nodes converge to the same stationary point[40  ###reference_b40###]. Our method switches between different communication graphs during training thus allowing workers to communicate with more neighbors than when keeping the topology fixed without increasing the total degree of the graph333Total degree is the total number of links in the communication network topology.. That equips our method with robustness to the problems faced by imbalanced and sparse topologies, and allows to achieve fast convergence and improved generalization performance in communication-constrained environments.\nWhat else is our contribution in this paper? The empirical analysis demonstrating that AL-DSGD converges faster, generalizes better, and is more stable in the communication-constrained environments compared to the SOTA approaches, and the theoretical analysis showing that the AL-DSGD algorithm that relies on dynamic communication graphs indeed achieves a sublinear convergence rate is all new. The proposed AL-DSGD is a meta-scheme algorithm that can be applied to most decentralized SGD algorithms. Given any decentralized algorithm as a baseline, AL-DSGD can accelerate its convergence while also improve robustness to imbalanced and sparse topologies. Finally, we release a general and concise PyTorch-based library for distributed training of deep learning models that supports easy implementation of any distributed deep learning approach ((a)synchronous, (de)centralized). The library is attached to the Supplementary materials and will be released publicly.\nThe paper is organized as follows: Section 2  ###reference_### contains the preliminaries, Section 3  ###reference_### motivates the proposed AL-DSGD algorithm, Section 4  ###reference_### presents the algorithm, Section 5  ###reference_### captures the theoretical analysis, Section 6  ###reference_### reports the experimental results, and finally Section 7  ###reference_### concludes the paper.

In the case of the D-PSGD algorithm, the weight matrices remain the same (denoted as ) for the whole training process and thus the communication topology remains fixed the whole time.\nThe communication between workers during training occurs over a computational graph, where the workers are represented as nodes and the edges denote the connections between them. The connectivity pattern is captured in . Similarly to D-PSGD, MATCHA starts with a pre-defined communication network topology. In contrast to D-PSGD, MATCHA allows the system designer to set a flexible communication budget , which represents the average frequency of communication over the links in the network. The sequence of the weight matrices  is constructed dynamically and depends on the choice of the budget .\nWhen  = 1, MATCHA is equivalent to vanilla D-PSGD algorithm. When , MATCHA carefully reduces the frequency of communication over each link (how quickly this is done depends upon the importance of the link in maintaining the overall connectivity of the graph). In addition, MATCHA assigns probabilities to connections between workers, thus they may become active in some iterations."

+            "text": "Previous literature [40  ###reference_b40###] explored how topology affects performance in distributed decentralized SGD optimizers. Denser networks lead to quicker error convergence in terms of iterations but introduce longer communication delays. In addition we discuss the lower degree-worse performance phenomenon in this section. In particular we show that the worker with lower degree will converge slower than the other nodes, and achieve worse final model at the end of training. We use Figure 1  ###reference_### and Table 1  ###reference_### to illustrate this phenomenon (refer to Section 6  ###reference_### regarding experimental details). Figure 1  ###reference_### shows that the node denoted as Node 4 achieves the slowest convergence before the first drop of the learning rate from among all of the workers.\nAs seen in Figure 2  ###reference_###, Node 4 possesses the lowest degree, with only Node 0 connected to it. Due to the weight matrix  design, weaker node performance adversely affects neighbors. Notably, in D-PSGD, Node 0 and Node 4 display reduced local training loss, yet their test accuracy lags behind other nodes. This is because the training loss is calculated using a local subset seen by the worker, and a lack of communication results in the over-fitting of the local model. This experiment shows that lower degree leads to slower convergence and worse final model (this phenomenon is observed in every single experiment with different random seeds).\nIn both D-PSGD and MATCHA, the output model is the average of models from all of the workers. Workers with lower degrees will naturally deteriorate the performance of the entire system. Therefore, a natural question arises: how to improve the performance of workers with low degrees and accelerate the overall convergence of the entire system without increasing the density of the network topology?"

A motivation example for Algorithm  1  ###reference_### can be found in figure 4  ###reference_###. A visualization of step 6 in Algorithm  1  ###reference_### can be found in Figure 3  ###reference_### and a visualization of step 7 (dynamic communication graphs) in Algorithm  1  ###reference_### can be found in Figure 5  ###reference_###. Let  denote the iteration index () and  denote the index of the worker (). Let  denote the best performing worker from among the workers adjacent to node  at iteration  and let  denote the maximum degree worker from among the workers adjacent to node  at iteration . Let  denote the dynamic communication graphs, each communication graph has its own weight matrices sequence . In the upcoming paragraphs of this section, we present novel contributions corresponding to Algorithm 1  ###reference_###.\nThe Corrective Force: To address the problem of detrimental influence of low degree nodes on the entire learning system, we first increase the influence of the workers with better performance () and larger degrees (). Specifically, in the communication step, workers send their model parameters, local training loss, and local degree to their neighbors. At the end of the communication, we determine the adjacent best worker () based on training loss and the adjacent maximum degree worker () based on local degree for each node. Then, at training we introduce an additional corrective \"force\" pushing workers to their adjacent nodes with the largest degrees and the lowest train loss according to the following:\nwhere  and  are pulling coefficients,  is the learning rate, and  is the gradient of the loss function for worker  computed on parameters  and local data sample  that is seen by worker  at iteration . This update is done in step 5 of the Algorithm 1  ###reference_###. Finally, note that no additional computations or communication steps are required to acquire the information about the best performing adjacent worker or the maximum degree adjacent worker for a given node. This is because during the training process we compute the training losses, and furthermore each worker must be aware of its degree and the degree of the adjacent worker before communication. Figure 4  ###reference_### intuitively illustrates that adding the corrective force can accelerate the convergence rate of the worker with low degree and worse performance.\nThe Averaging Step: Secondly, when averaging workers, we weight them according to their degree and performance (see step 6). This is done according to the formula:\nWe visualize the process in Figure 3  ###reference_###. Take node  as an example. Figure 3  ###reference_###(a) to 3  ###reference_###(b) shows the classical communication step in vanilla decentralized SGD algorithms. Since the node , that is adjacent to node , has the largest degree and node  itself is the best-performance worker, we increase the weight of node  and node  in Figure 3  ###reference_###(c).\nThe Dynamic Communication Graph: Third, instead of relying on a single communication graph, we introduce  graphs with different topologies and switch between them (see Figure 5  ###reference_### for the special case of ). The total degree of each graph is the same as for the baseline. When we switch the graph, we are indeed altering the physical network topology. Since distributed machine learning models are trained on data center clusters, where workers can communicate with each other, switching communication graph won\u2019t lead to additional training time.\nWe randomly choose a graph to start with and switch between different graphs after each training iteration.\nBy using the dynamic communication graph, the workers are connected to more neighbors. This is done without increasing the total degree of the graph. This allows us to balance the expected degree of each node and avoid the poor performance of nodes with extremely low degrees.\nFinally, we would like to emphasize that ALD-SGD is a meta-scheme that can be put on the top of any decentralized SGD method, including D-PSGD and MATCHA.\n###figure_4### ###figure_5###"

MATCHA and MATCHA-based AL-DSGD results are in Appendix F  ###reference_###, Table 10  ###reference_###. Training loss, shown in Figure 6  ###reference_### and 7  ###reference_###, assesses convergence better due to unstable test loss. AL-DSGD reduces variance between nodes and speeds up convergence for the worst-performing node.\nIn summary, AL-DSGD has enhanced the test accuracy for both the average and worst-performing models. Tables 2  ###reference_### and 10  ###reference_### reveal AL-DSGD\u2019s superior generalization over other methods. For the case of D-PSGD, the test accuracy has increased by resp.  and  in the worst-performance worker and by resp.  and  in the final averaged model for CIFAR-10/ResNet50 and CIFAR-100/WideResNet tasks, respectively, when putting AL-DSGD on the top of D-PSGD. For the case of MATCHA, even though the AL-DSGD does not dramatically increase the baseline performance for CIFAR-10/ResNet50 task because the model is relatively simple, it strongly outperforms the baseline on more complicated CIFAR100/WideResNet task. As shown in Figure 12  ###reference_### in the Appendix F  ###reference_###, AL-DSGD demonstrates more stable (i.e., smaller discrepancies between nodes) and faster convergence compared to MATCHA.\nWe would like to further emphasize that, except for converging to a better optimum, another significant advantage of our AL-DSGD algorithm is that it is much more robust to imbalanced and sparse topology, as will be discussed in the following section."

The experiments overall demonstrate that AL-DSGD has enhanced test accuracy in scenarios involving either imbalanced or sparse topologies. Our approach relies on a dynamic communication graph with three Laplacian matrices (Figure 5  ###reference_###). The results are shown here, and the results using two Laplacian matrices are in Appendix E  ###reference_###. Tables 2  ###reference_### and Table 10  ###reference_###(in Appendix D  ###reference_###) demonstrate that D-PSGD-based AL-DSGD and MATCHA-based AL-DSGD are more robust to imbalanced topologies. To further evaluate AL-DSGD in communication-limited environments, we gradually reduce the communication graph\u2019s degree to simulate sparse topology (Figure 8  ###reference_###) and compare AL-DSGD\u2019s performance with D-PSGD (Figure 9  ###reference_###). AL-DSGD remains stable and robust to sparse topologies, as its performance does not significantly decrease until the degree is reduced to 38%, while D-PSGD performs poorly even when the degree is only decreased to 84%.\nFinally, Table 3  ###reference_### includes the comparison of D-PSGD, MATCHA, and AL-DSGD. We applied AL-DSGD on the top of both the D-PSGD and MATCHA baselines and compared the results. Table 3  ###reference_### further confirms the claim that the AL-DSGD algorithm is highly robust to sparse topologies, as it consistently achieves better test accuracy compared to the baseline algorithms, D-PSGD and MATCHA, for nearly all the cases, particularly in sparse topology scenarios.\nMore details can be found in Appendix D  ###reference_### & F  ###reference_###."

Without dynamic communication graphs, when applying addictive force according to loss performance, the worker with worse performance and smaller local training loss will affect other workers. The final test accuracy of the worker with less degree did not improve. The results indicate that without dynamic communication graphs, ALD-SGD, which only applies corrective forces, does not achieve better performance. This is because the workers with low degree overfit and negatively affect the others. Similar results are observed when only one corrective force or only the dynamic communication graph is applied.\n###figure_10### figureResNet-50 model trained on CIFAR-10.

(b) Previous methods simply average the training model with neighbors. Each colored block denotes the identity of workers whose parameters were taken to compute the average. (c) To illustrate AL-DSGD, we assume that the higher is the index of the worker, the worse is its performance in this iteration. For each node, in addition to averaging with neighboring models, AL-DSGD assigns additional weights to the best performing adjacent model and the maximum degree adjacent model. This is depicted as the sum, where the additional block has two pieces (the left corresponds to the best performing adjacent model and the right corresponds to the maximum degree adjacent model; the indexes of these models are also provided). For example, in the case of model 2222, both the best-performing adjacent model and the maximum degree adjacent model is model 1111.",

+    "abstract": "The Vision-Language Foundation model is increasingly investigated in the fields of computer vision and natural language processing, yet its exploration in ophthalmology and broader medical applications remains limited. The challenge is the lack of labeled data for the training of foundation model. To handle this issue, a CLIP-style retinal image foundation model is developed in this paper. Our foundation model, RET-CLIP, is specifically trained on a dataset of 193,865 patients to extract general features of color fundus photographs (CFPs), employing a tripartite optimization strategy to focus on left eye, right eye, and patient level to reflect real-world clinical scenarios. Extensive experiments demonstrate that RET-CLIP outperforms existing benchmarks across eight diverse datasets spanning four critical diagnostic categories: diabetic retinopathy, glaucoma, multiple disease diagnosis, and multi-label classification of multiple diseases, which demonstrate the performance and generality of our foundation model. The sourse code and pre-trained model are available at https://github.com/sStonemason/RET-CLIP.",

+            "text": "Foundation models trained on large-scale, multi-task datasets are now becoming increasingly popular and have achieved success in the fields of computer vision and natural language processing. Foundation models excel in generalization in feature extraction, offering significant potential for addressing the complex challenges of clinical applications. However, the development of medical foundation models is still in its nascent phase, primarily hindered by the lack of high-quality data and concerns around patient privacy. Although initial efforts have been made [23  ###reference_b23###, 19  ###reference_b19###, 24  ###reference_b24###, 9  ###reference_b9###, 12  ###reference_b12###, 6  ###reference_b6###, 11  ###reference_b11###], the effectiveness of these models, particularly in analyzing retina fundus images, has yet to meet expectations, underscoring the urgent need for focused advancements in this area.\nIn the clinical diagnosis and treatment of ocular diseases, medical imaging, such as color fundus photography (CFP), and the detailed image interpretations and diagnostic reports written by professional ophthalmologists are indispensable. This makes the clinics of ophthalmology inherently rich in image-text multi-modality data, which holds significant potential for enhancing clinical applications. RETFound [25  ###reference_b25###] is a foundation model for retinal images based on self-supervised learning. However, it solely utilizes image data and overlooks the equally vast amount of clinical diagnostic text. To address this limitation, CLIP [17  ###reference_b17###], a powerful vision-language self-supervised paradigm, is widely explored in foundation models. By aligning the information of image and text in a shared representation space using a large corpus of image-text pairs, CLIP-style models can understand and associate visual content with natural language information. This results in feature representations with stronger generalization capabilities. Many studies focus on training vision-text models in the medical field [23  ###reference_b23###, 19  ###reference_b19###, 9  ###reference_b9###, 22  ###reference_b22###, 18  ###reference_b18###, 7  ###reference_b7###, 20  ###reference_b20###, 2  ###reference_b2###]. PMC-CLIP [9  ###reference_b9###] collects image-description pairs from large amount of scientific documents and trains a CLIP-style model based on them. FLAIR [18  ###reference_b18###] is a pre-trained vision-language model designed to understand retinal fundus images. The textual data utilized in such research often comes from captions in medical papers or through the manual annotation of simple labels. However, clinical diagnostic reports, rich in valuable textual information, remain underutilized in this context.\nMoreover, the conventional approaches often involve treating CFPs of individual eyes as separate entities during model training. This necessitates the extraction of information corresponding to each eye from the original clinical diagnostic reports, which may not always clearly differentiate between left and right eyes. The manual processing involved in this procedure requires specialized knowledge and could introduce errors and increase costs significantly due to the potential for human-induced noise. Conversely, considering both eyes of a patient together provides a more holistic and clinically meaningful approach in clinical scenarios.\nTo alleviate the above issues, we have the following contributions in this paper: Firstly, we propose a vision-language foundation model for CFPs, named RET-CLIP, which we believe is the first attempt to leverage clinical diagnostic reports to build a retinal foundation model, enriching the model\u2019s visual encoding capabilities with practicality and authenticity. The diagnostic reports in Chinese are included, extending the linguistic versatility of the research domain beyond English. Secondly, a novel strategy is proposed to decouple the information of left and right eyes in diagnostic reports, which is a simple yet effective paradigm for building a retinal foundation model. In practical scenarios, diagnostic reports are usually patient-level, mixing information from both eyes, which brings a big challenge for directly using CLIP to build foundation models. The proposed monocular and patient-level contrastive learning approach can handle this challenge in the ophthalmology domain. Lastly, our model achieves state-of-the-art performance across diverse tasks and datasets, confirming the effectiveness of the proposed training strategy."

The augmentation includes random crop followed by resizing to , random horizontal flipping, color jitter, and image normalization. For diagnostic reports, we focus on correcting typos and consecutive punctuation errors caused by human input, restoring abbreviations to their full expressions, unifying mixed Chinese and English expressions into Chinese to align with our text encoder\u2019s language capabilities, and ensuring the text is coherent and grammatically correct by manual scrutiny.

RET-CLIP consists of a visual encoder and a text encoder, which extract image features from CFPs and text features from clinical diagnostic reports, respectively. During pre-training, image-text contrastive learning is performed at the monocular and patient level jointly. Patient level examines data features from a holistic patient perspective, effectively leveraging the information in raw data while minimizing the interference of manual preprocessing in the pre-training phase. Concurrently, the binocular level guides the model towards acquiring finer-grained features than the patient level. Combined together, these methodologies can improve RET-CLIP\u2019s performance.\n###figure_1### Given a mini-batch containing  binocular images-text triplets (i.e.,  patients), , where ,  and  represents the CFP of left eye, the CFP of right eye and the diagnostic report of the th patient, respectively. The visual encoder takes  and  as input, while the text encoder is fed with .\nVisual encoder.\nThe left and right  CFPs for a patient are encoded to the embedding dimension of  using a ViT-based [5  ###reference_b5###] encoder  respectively:\nwhere  and  represent the image features of the left and right eye, respectively. Next, concatenation and a simple Multilayer Perceptron (MLP)  are employed to merge the image features of left and right eyes to derive comprehensive patient-level image features:\nwhere  denotes concatenation.\nText encoder.\nFor a given patient\u2019s diagnostic report , a BERT-based [4  ###reference_b4###] encoder  is implemented to encode the clinical descriptions with a text token of length :\nwhere  denotes the sentence embedding,  denotes the embedding for [CLS] token. We then implement three stacked two-layer nonlinear MLPs , ,  to decouple  into textual features representing the left eye, right eye, and patient level, termed as , , and , respectively:"

These tasks contain four main categories: diagnosis of diabetic retinopathy, glaucoma, multiple diseases, and multi-label classification of multiple diseases.\nFor diabetic retinopathy diagnosis, IDRID [16  ###reference_b16###] and APTOS-2019 (https://www.kaggle.com/competitions/aptos2019-blindness-detection/data) are used. The labels for diabetic retinopathy are no, mild, moderate, severe, and proliferative retinopathy. The IDRID dataset comprises 516 images, while the APTOS dataset contains 3662 images.\nFor glaucoma diagnosis, PAPILA [8  ###reference_b8###] (488 images in total) and Glaucoma Fundus [1  ###reference_b1###] (1544 images in total) are used. They both have three categorical labels, non-glaucoma, suspected glaucoma (early glaucoma), and glaucoma (advanced glaucoma).\nFor multiple disease diagnosis, JSIEC [3  ###reference_b3###] (1000 in total) and Retina (https://www.kaggle.com/datasets/jr2ngb/cataractdataset) (601 in total) are tested. JSIEC contains 39 categories of common referable fundus diseases and conditions. Retina includes labels for normal, glaucoma, cataract, and other retinal diseases.\nFor multi-label classification of multiple diseases, RFMID [15  ###reference_b15###] and ODIR (https://odir2019.grand-challenge.org/) are tested. RFMID includes 3200 images with 28 categories of common referable fundus diseases and conditions. ODIR includes 10000 images (5000 patients\u2019 paired left and right eyes) with labels of normal, diabetic retinopathy, glaucoma, cataract,age-related macular degeneration (AMD), hypertension, myopia, and other diseases.\nFor the IDRIR, the entire dataset is officially divided into a test set comprising 20% of the data, with the remaining 80% designated as the training set. In our experiments, we further split the training set into a training set and a validation set using a 4:1 ratio. Similarly, for the PAPLA, we follow the official partitioning method, which aligns with the approach described above. Regarding the RFMID, the official division includes distinct sets for training, validation, and testing; we adhere to this official partitioning. For all other datasets, we divide them into training, validation, and test sets using a 0.56:0.14:0.3 ratio, following RETFound\u2019s [25  ###reference_b25###] partitioning method. For all datasets, samples within each category are initially distributed based on the specified proportions before being combined to ensure consistent category distribution across the training, validation, and test sets.\nWhen adapting to downstream tasks, the input image is mapped to a high-level feature representation by the visual encoder. A simple linear prediction head is then applied, followed by a Sigmoid or Softmax layer to achieve classification.\nFor each task, two adaptation methods are implemented: linear probing, training the classifier only with the encoder frozen, and fine-tuning, where both the encoder and classifier are trained. Each evaluation process consists of 50 epochs with a batch size of 16. The model weights with the best performance on the validation set are saved for testing."

This outcome substantiates RET-CLIP\u2019s robust feature extraction and generalization capabilities. Furthermore,\nit suggests that RET-CLIP not only captures high-quality features but also exhibits strong adaptability, enabling effective customization for specific tasks.\nIt\u2019s noteworthy that the previous foundation models designed for CFPs do not exhibit an advantage over models trained on non-CFP datasets. RETFound\u2019s [25  ###reference_b25###] image reconstruction-focused paradigm may prioritize features related to the rebuilding of CFP, which lack the granularity and quality needed for specific downstream tasks, hindering its broader applicability. FLAIR [18  ###reference_b18###], while is a CLIP-style model, does not suit ophthalmic tasks as it uses the text provision method employed by the original CLIP [17  ###reference_b17###], which is designed for natural contexts, offering limited textual insights from single labels. Moreover, its dependence on public datasets for training constrains its performance due to their limited scale and quality. In contrast, RET-CLIP leverages rich textual information from clinical reports to extract detailed features for ophthalmic tasks better, showcasing the benefits of integrating diagnostic reports into the training of medical CLIP-style models."

We observe that commonly used time series models struggle to utilize the prior correlation between price and demand-supply, which, we found, can contribute a lot to a reliable electricity price forecaster. Leveraging this prior, we propose a simple piecewise linear model that significantly enhances forecast accuracy by directly deriving prices from readily forecastable demand-supply values. Experiments in the day-ahead electricity markets of Shanxi province and ISO New England reveal that such forecasts could potentially save residents millions of dollars a year compared to existing methods.

Modern society relies heavily on a stable supply of electrical energy, but the cost can be a significant financial burden. Ensuring reliable power supply while reducing living costs is vital, especially for low-income populations. In some countries, residents buy electricity directly from the market, while in others, state-owned companies purchase and retail it. Regardless of the form, the electricity price in the power market directly affects residents\u2019 cost. Prices fluctuate throughout the day, leading to varying consumption costs (Bielen et al. 2017  ###reference_b4###). Advanced energy storage systems allow residents to buy electricity during low-price periods and use stored energy during high-price periods, reducing expenses. This strategy relies on accurate price forecasts, which directly impact financial savings (Zheng et al. 2020  ###reference_b54###; Gil et al. 2012  ###reference_b11###). Therefore, effective electricity price forecasting is essential for optimizing residents\u2019 revenue and enhancing societal welfare.\nThe day-ahead market is a pivotal part of the electricity market, and this paper focuses on forecasting day-ahead electricity prices. Forecasting electricity prices involves various tasks depending on the specific market: Day-ahead, Intra-day, or Balancing markets (Maciejowska, Uniejewski, and Weron 2022  ###reference_b22###). Among these, the day-ahead market is the most significant, attracting the majority of traders (Castelli, Groznik, and Popovi\u010d 2020  ###reference_b5###).\nCurrent methods for forecasting day-ahead electricity prices often underperform. These approaches primarily involve the straightforward adaptation of general Time Series Forecast (TSF) models to the day-ahead electricity market (Lago et al. 2021  ###reference_b16###). However, the electricity market is characterized by large price fluctuations, a lack of clear periodicity and temporal non-stationarity. Consequently, existing methods may not be effective (Patel and Shah 2021  ###reference_b31###).\nCurrent forecasting methods are limited by their inability to capture the strong, variable correlations between prices and supply-demand. The price formation mechanism in the electricity market is clear and well-understood; economics indicates that prices are determined by the balance between supply and demand (Martin, M\u00fcller, and Pokutta 2013  ###reference_b24###). Therefore, the correlation between electricity prices and market supply-demand is crucial for accurate forecasting (Ziel and Steinert 2016  ###reference_b57###). However, TSF methods struggle with this. Some approaches just ignore the impact of supply-demand variables (Zeng et al. 2023  ###reference_b51###; Nie et al. 2022  ###reference_b26###), while others trying to use data-driven methods to model these correlations (Liu et al. 2023a  ###reference_b19###; Zhang and Yan 2023  ###reference_b52###). Nonetheless, we find that in trained models, these correlations do not significantly contribute to forecasting results.\nWe propose a simple model to forecast day-ahead electricity prices by modeling the correlation between prices and supply-demand. Instead of directly using TSF models to forecast prices, we utilize supply-related variables forecasted by TSF models and focus on establishing the correlation between these variables and prices based on the price formation mechanism. This approach avoids the weaknesses of current TSF models in capturing variable correlations and provides better interpretability. Specifically, we introduce the assumption of the short-term stability of the supply curve, under which we can forecast the correlation between supply and price using recent historical data. We fit the supply curve using a simple Correlation-based Piecewise Linear Model (CoPiLinear), then use this and the forecasted demand to forecast the price, as Figure 1  ###reference_### shows.\n###figure_1### In summary, our main contributions include:\nBy analyzing the price formation mechanism in the market, we identify the limitations of current models. We introduced a new correlation-based forecasting approach, bridging the gap between the day-ahead electricity price forecasting problem and existing TSF models.\nTo our knowledge, this is one of the first efforts to forecast electricity prices by considering the price formation mechanism in the day-ahead market. We introduce a short-term stability assumption based on market characteristics to simplify supply curve forecasting.\nExtensive experiments show that our simple method outperforms complex state-of-the-art time (SOTA) models. We demonstrate the revenue of improved electricity price forecasting accuracy for residents, highlighting the significant potential and social impact of the day-ahead electricity price forecasting problem."

The first type focuses on the temporal dependency of the target variable, capturing patterns like periodicity and trends. This includes univariate and channel-independent multivariate TSF models. The second type, in addition to considering the temporal dependency of the target variable, also takes into account the correlation between the target variable and auxiliary variables, represented by various channel-dependent multivariate TSF models.\nTSF models emphasize end-to-end forecasting. Advanced second type methods generally capture inter-variable correlations through modules like MLP and attention in parts of the model\u2019s substructure. This approach introduces additional parameters and makes it challenging to intuitively explain the correlations between variables. Moreover, advanced second type methods do not achieve more accurate forecasts with more information as intended. This has been demonstrated by the superior performance of first-type methods like TimesNet (Wu et al. 2022  ###reference_b44###) and PatchTST (Nie et al. 2022  ###reference_b26###) on numerous multivariate datasets.\nModeling the price formation mechanism aligns with economic theory but faces practical challenges due to data unavailability. Accurate projection of supply and demand curves requires data on production and purchase propensities at various price points. However, obtaining comprehensive data is difficult in extensive markets due to the private nature of individual buying and selling decisions, complicating precise measurements of willingness to buy or sell at each price.\nThe summary of related work is listed in Table 1  ###reference_###. The Model column indicates the primary model used for forecasting in the literature. The Domain-Specific column shows whether the method is tailored for day-ahead electricity price forecasting. A  in the Domain-Specific column denotes methods developed for economic research, not applicable in many markets. The Variable Correlation column reflects if the literature leverages variable correlations for forecasting."

Prices for each time slot is independently determined through an auction-based system (Shi et al. 2023  ###reference_b37###), driven by supply and demand dynamics. Take the day-ahead electricity market in Shanxi Province, China, as an example. There are 96 trading time slots in a day, each 15 minutes long. As shown in Figure 2  ###reference_###, an authoritative third party announces the day-ahead electricity prices for day  and other forecast variables on day D, then market participants submit their bids before the day  market closes. The third party considers anticipated production and costs reported by power producers and accounts for constraints such as grid dispatch limitations, operational characteristics of power plants, and emergency reserves. Through optimization calculations, generation schedules and dispatch plans are coordinated to meet societal electricity demand. Power generation companies then formulate their production plans based on the finalized schedule (sha 2023  ###reference_b2###). Through this pricing process of balancing supply and demand, the day-ahead electricity prices for day  in the entire Shanxi market is determined."

In the ISO New England market, while 75% of prices are below $40/MWh, peaks can reach $300/MWh. This irregularity and lack of clear time series patterns result in poor performance of baseline models, especially time series forecasting models, in forecasting high prices (Rahaman et al. 2019  ###reference_b34###; Xu 2020  ###reference_b48###).\nHigh prices are mainly driven by high demand, which can help forecast these irregularities. However, TSF models struggle to capture the correlation between prices and supply-demand dynamics. According to the price formation mechanism, forecasted demand should significantly impacts forecasted price. Yet, even with substantial changes in demands, existing models show minimal price variation. This inconsistency with real market behavior indicates that these models do not adequately incorporate supply and demand variables, leading to poor forecasting performance. See Appendix A for detailed experiment results.\nIn Figure 3  ###reference_###, the ISO New England Dataset from July 17, 2023, shows forecasted peak demand surpassing the previous week\u2019s peak, indicating high prices. Models based solely on temporal dependence fail to account for forecasted demand, leading to inaccurate high price forecasts. While existing TSF models that capture variable correlations perform better in predicting price trends, they underestimate price increases during significant demand surges, overlooking the price formation mechanism."

Based on related work (Zheng et al. 2020  ###reference_b54###), we formulate an optimization problem for the purchasing strategy, using given forecast prices and the energy storage systems. The cost savings from this strategy represent the economic revenue of price forecasts, and improved forecast accuracy enhances the revenue. The purchasing cost  reaches its theoretical minimum  if forecasts match actual prices perfectly. Without the strategy, the cost is . The economic revenue  equals .

Forecasting precise supply and demand curves is impractical due to the need to forecast individual trading decisions at various price levels. Obtaining such detailed data is challenging because of the private nature of these decisions.\nTo address this issue, we introduce the assumption of the short-term stability of the supply curve. Using recent historical data, we reconstruct the supply-price correlation and obtain a forecast for the future supply curve. We fit the supply-price relationship using a simple Correlation-based Piecewise Linear Model (CoPiLinear). With this curve and supply volume forecasted by TSF models, we can forecast the price, as Figure 1  ###reference_### shows."

Commodities from different electricity power generators are homogenized, making the supply curve equivalent to the marginal cost (Roberts 1987  ###reference_b35###). Notably, within a supplier, the marginal cost is primarily dictated by the load rate rather than the supply quantity. The load rate reflects the generator\u2019s operating conditions, which directly impact costs (Roozbehani et al. 2022  ###reference_b36###): costs rise rapidly when transitioning from standby to startup, slow down upon reaching a stable segment, and surge again if a backup unit is activated. Due to managerial inertia, power plants typically do not alter operational units over several consecutive days, leading to a stable correlation between marginal cost and load rate during this period. More details about the short-term stability are listed in the Appendix B.\nUsing the load rate instead of supply quantity as the horizontal axis of the supply curve, the correlation between price and load factor exhibits short-term stability over recent days. This conversion is straightforward by dividing the supply quantity by the capacity on that day.\nAs shown in Figure 4  ###reference_###, we selected a period from March 23, 2023, to April 3, 2023, within the Shanxi day-ahead electricity market to illustrate the short-term stability. The supply curve shape remains relatively stable across several consecutive days, requiring only minor shifts for approximate overlap. By using the load rate instead of supply quantity, we can align the supply curves of adjacent dates. This alignment reveals the short-term stability of the supply curve over consecutive days. Additionally, the similarity of supply curves decreases with longer intervals between dates."

Our challenge is to determine the recent supply curve without data on willingness to buy or sell at each price. While the demand curve position varies significantly at different time slots, the supply curve remains relatively stable. We can get historical equilibrium day-ahead electricity prices and power supply volume at various trading time slots, corresponding to the intersections of the supply and demand curve. These intersections, all on the same supply curve, can be used to fit the supply curve in reverse, as shown in Figure 5  ###reference_###.\nWe use the most relevant historical data to ensure accuracy. Supply curves are more similar between closer dates, as shown in Figure 4  ###reference_###. Therefore, our initial step is to identify and select the most suitable historical data. We model the supply curve for each day and examine these curves for deviations in shape. If a deviation exceeds a threshold, we retain only the data after the deviation.\nThe necessity for the most recent dates limits the amount of usable data, so it is imperative to employ a model that is relatively simple and easy to fit the supply curve. We represent the supply curve with a piecewise linear function, reflecting its phases with different slopes. Due to power plant generator characteristics (Roozbehani et al. 2022  ###reference_b36###), the supply curve consistently exhibited piecewise phases: rapid growth, steady growth, and then rapid growth again. Therefore, we employ the simplest form of a n-segment piecewise linear function to represent the supply curve, named CoPiLinear. The slopes and intercepts of the n lines are represented by , ,  ,  and , , ,  respectively. And , ,  is the breakpoints of the piecewise linear function.\nWe optimize the parameters using historical equilibrium points data. Throughout the day, we can observe prices and load rates at various transaction time slots. These correspond to scatter points on the supply and demand curve plane, note as , , , . The set of scatter points includes the closest  days\u2019 data, each day has  time slots. The goal is to fit these scatter points with CoPiLinear, minimizing the sum of distances from all points to the n-segment line. The final constraint equation ensures the continuity of the supply curve.\nFitting piecewise linear lines is a well-established problem with mature solutions. We use the Python package pwlf (Jekel and Venter 2019  ###reference_b14###) to quickly approximate the supply curve. However, direct application that package on certain datasets may result in inaccuracies. To enhance fitting accuracy, we employ specific techniques detailed in Appendix C."

The forecasted capacity data is used to adjust the horizontal axis of the CoPiLinear model from load rate to supply volume, creating the actual supply curve. The forecasted demand volume is then input into the CoPiLinear model to obtain the forecasted price.\nThese variables exhibit strong periodicity, making TSF models particularly effective, as detailed in Appendix D. Given their importance for the market, numerous mature TSF methods exist. Many service providers and market operators offer forecast data to aid market participants\u2019 decision-making, so we directly utilize publicly available forecasts from third parties. In markets lacking forecasts for certain variable, such as capacity, we employ a simple model, Random Forest, to generate the necessary forecasts."

For variable correlations, we selected domain-specific methods including Linear (Uniejewski, Nowotarski, and Weron 2016  ###reference_b40###), SVM (Prahara and Hariadi 2022  ###reference_b33###), XGBoost (Manfre Jaimes et al. 2023  ###reference_b23###), DNN (Lago, De Ridder, and De Schutter 2018  ###reference_b15###), and Lasso-RF (Ludwig, Feuerriegel, and Neumann 2015  ###reference_b21###), along with generic TSF methods such as Koopa (Liu et al. 2023b  ###reference_b20###), TSMixer (Chen et al. 2023b  ###reference_b8###), Informer (Zhou et al. 2021  ###reference_b55###), Autoformer (Wu et al. 2021  ###reference_b45###), FEDformer (Zhou et al. 2022  ###reference_b56###), Crossformer (Zhang and Yan 2023  ###reference_b52###), and iTransformer (Liu et al. 2023a  ###reference_b19###). The variables used in these generic TSF models are exactly the same as those in the CoPiLinear, including historical price, capacity, demand data and forecast demand, weather data.\nTo simulate real market applications, our model uses a daily rolling training method, adding new data each day for retraining. All baselines also adopt this method, updating the training and validation sets daily. Deep learning methods with short training sets tend to perform poorly. To improve accuracy, we use the longest possible training set and adjust hyperparameters during testing. More baseline details are in Appendix F."

However, TSF models struggle to capture the correlation between prices and supply-demand dynamics. According to the price formation mechanism, forecasted demand should significantly impacts forecasted price. Yet, even with substantial changes in demands, existing models show minimal price variation. This inconsistency with real market behavior indicates that these models do not adequately incorporate supply and demand variables, leading to poor forecasting performance. See Appendix A for detailed experiment results.\nTo investigate this, we alter the demand for the target date, setting it to zero or doubling it, while keeping other inputs constant. Using data from Shanxi province for January 2024, we examine the impact of significant demand changes on the forecasted prices of four models: DNN, Lasso-RF, iTransformer, and Crossformer. The first two models are commonly used in day-ahead electricity price forecasting, while the latter two are state-of-the-art (SOTA) TSF models that consider relationships between variables. The sMAPE between the forecasted prices before and after the change is generally small, not exceeding 20%, as shown in Table. 5  ###reference_###. Figure 8  ###reference_### shows the forecasted prices for January 15th, with minimal changes even when demand is significantly altered.

It is important to highlight that our methodology remains applicable in addressing the future\u2019s needs, which include the anticipation of increased deregulation, the integration of renewable resources, and the implementation of energy storage solutions. Due to the high cost of thermal power generation, as long as it exists, it will serve as the marginal price of the supply curve. The instability of renewable energy generation and the inertia of social transition determine that thermal power generation is difficult to be completely eliminated in the foreseeable future, so the short-term stability assumption of the supply curve can still apply for a long time. As the proportion of renewable energy generation increases and energy storage technology develops, if thermal power generation has not been completely eliminated at this time, our method still applies according to the previous analysis, and even because of the progress of energy storage technology, the cost of supply during peak and trough periods will be more similar, which actually enhances our assumption of short-term stability (the supply curve is more like a horizontal line); if renewable energy occupies all power generation shares, the supply curve at that time may be more affected by storage scheduling costs, which also have short-term stability. Of course, these need to be studied in depth after the relevant technologies mature. It is worth mentioning that in the Shanxi market we analyzed, the proportion of renewable energy generation has already reached more than half, far higher than the global average level (30%), and our method still works well. As for the increased market deregulation, our method comes from the principle of supply and demand and is still applicable in a free market. The ISO dataset in the experimental part is heavily deregulated markets, and the electricity price is determined by the transaction price. In summary, we believe that the assumption of short-term stability of the supply curve can be established in a wide range of time and space."

+            "text": "In the field of 3D vision, integrating multiple data modalities such as text, images, and point clouds has shown great potential for enhancing object recognition and scene understanding. This multi-modal approach is vital for applications in mixed reality  (Dargan et al. 2023  ###reference_b15###; Mendoza-Ram\u00edrez et al. 2023  ###reference_b43###), autonomous navigation (Chen et al. 2020a  ###reference_b10###; Tan, Robertson, and Czerwinski 2001  ###reference_b57###) and 3D scene understanding (Armeni et al. 2016  ###reference_b5###; Liu et al. 2021  ###reference_b40###; Vu et al. 2022  ###reference_b60###), where accurate 3D perception is crucial. Recent advancements in multi-modal learning have underscored their capability in this domain, with notable contributions from seminal works like PointCLIP (Zhang et al. 2022d  ###reference_b74###; Zhu et al. 2023  ###reference_b79###), CLIP2 (Zeng et al. 2023  ###reference_b69###), ULIP (Xue et al. 2023a  ###reference_b65###, b  ###reference_b66###), OpenShape (Liu et al. 2024  ###reference_b38###), and TAMM (Zhang, Cao, and Wang 2024  ###reference_b77###). These studies have demonstrated the effectiveness of leveraging text, images, and point clouds to improve 3D object recognition and understanding.\n###figure_1### However, a significant challenge remains in effectively aligning and utilizing these heterogeneous data sources to optimize model performance.\nWith recent advancements in 3D vision, there\u2019s a growing emphasis on multi-modal learning approaches. These frameworks are becoming increasingly crucial, especially when it comes to processing and learning from multi-modal data, which integrates textual information, 2D images, and 3D point cloud data.\nDespite the success of these approaches, there is a notable gap in the literature regarding multi-modal data augmentation. The cohesive augmentation of triplets has the potential to unlock further performance improvements by enriching the diversity of data and promoting better alignment across modalities. This presents a promising avenue for research to explore comprehensively the benefits of multi-modal learning frameworks.\nIn previous studies, many mixing-based data augmentation\nmethods have been proposed for point cloud (Kim et al. 2021  ###reference_b32###; Rao et al. 2021  ###reference_b51###; Lee et al. 2022  ###reference_b34###). Mixing-based methods like PointCutMix (Zhang et al. 2022b  ###reference_b71###) and PointMixup (Chen et al. 2020b  ###reference_b12###) enhance training data diversity through techniques such as region splicing and feature interpolation. By introducing controlled perturbations and heterogeneity into the training process, these approaches enable models to learn invariant and discriminative features, thereby improving their robustness and generalization to diverse and unseen data distributions (Umam et al. 2022  ###reference_b58###; Kim et al. 2021  ###reference_b32###; Wang et al. 2024  ###reference_b62###).\nHowever, the potential of mixing-based methods in multi-modal scenarios remains largely unexplored. Integrating mixing-based techniques with multi-modal alignment could enhance multi-modal learning by generating diverse feature spaces, fostering robust cross-modal correspondences, and revealing invariant features across modalities. This leads to an important question: Can we design a simple yet effective framework that improves alignment quality and stability while enhancing model generalization through augmented, coherent multi-modal representations?\nTo address this issue, we introduce MM-Mixing, a multi-modal approach for 3D understanding that integrates mixing-based methods with multi-modal triplet data. Our two-stage training pipeline combines feature-level and input-level mixing to optimize the 3D encoder, enhancing intermodality relationships and promoting generalization.\nIn the first stage, MM-Mixing leverages feature-level mixing and contrastive learning to align mixed 3D features with their corresponding modalities. This mixing-based alignment strategy fosters consistency across different modalities and significantly enhances the 3D encoder\u2019s cross-modal understanding. Specifically, by aligning point cloud mixed features with text mixed features, we capture semantic information that provides a contextual understanding of the 3D shapes. Additionally, aligning point cloud mixed features with image mixed features bolsters the capture of intricate visual details and spatial relationships. This dual alignment of mixed features not only ensures cross-modal consistency but also amplifies the 3D encoder\u2019s ability to understand and represent complex, multi-modal data effectively.\nThe second stage incorporates feature-level and input-level mixing, introducing mixed point cloud inputs to refine 3D feature representations further. By aligning mixed point cloud features with feature-level mixed point cloud features, we enhance the network\u2019s ability to capture and represent variations and nuances within the data, resulting in more robust and discriminative feature representations. This stage generates diverse and realistic samples that enhance the 3D encoder\u2019s ability to generalize across different datasets.\nBy seamlessly integrating these methods, MM-Mixing significantly boosts the baseline model\u2019s performance across various settings, including zero-shot 3D classification, linear probing 3D classification, and cross-modal 3D shape retrieval, while remaining straightforward to implement and integrate into existing 3D understanding frameworks.\nOur main contributions can be summarized as follows:\nWe introduce MM-Mixing, a novel multi-modal mixing alignment framework specifically designed for multi-modal data, addressing a previously unexplored issue in 3D understanding, which can be easily integrated with existing frameworks.\nAn efficient two-stage framework is proposed that integrates feature-level and input-level augmentation to optimize the 3D encoder, enhance cross-modal relationships, and promote generalization.\nOur MM-Mixing not only strengthens the 3D understanding of models but also significantly enhances cross-dataset generalization, demonstrating exceptional performance in downstream tasks such as zero-shot 3D classification, linear probing 3D classification, and cross-modal retrieval."

+            "text": "3D Understanding.\nUnderstanding 3D structures is a crucial aspect of computer vision (Peng et al. 2023  ###reference_b45###; Qi et al. 2023  ###reference_b48###; Rozenberszki, Litany, and Dai 2022  ###reference_b54###; Zhang et al. 2022a  ###reference_b70###; Zhang, Dong, and Ma 2023  ###reference_b72###).\nRecent developments in 3D understanding have largely focused on leveraging advanced representation learning techniques (Abdelreheem et al. 2023  ###reference_b1###; Achituve, Maron, and Chechik 2021  ###reference_b2###; Achlioptas et al. 2018  ###reference_b3###; Aneja et al. 2023  ###reference_b4###; Deng, Birdal, and Ilic 2018  ###reference_b17###; Hess et al. 2023  ###reference_b26###; Guo et al. 2023b  ###reference_b22###). Three primary methodologies have emerged: projecting-based methods where 3D point clouds are projected into various image planes (Su et al. 2015  ###reference_b56###; Kanezaki, Matsushita, and Nishida 2018  ###reference_b31###; Goyal et al. 2021  ###reference_b20###; Chen et al. 2017  ###reference_b11###), voxel-based methods which transform the point clouds with 3D voxelization (Song et al. 2017  ###reference_b55###; Riegler, Osman Ulusoy, and Geiger 2017  ###reference_b53###; Canfes et al. 2023  ###reference_b6###), and direct modeling of 3D point clouds with point-centric architectures (Qian et al. 2022  ###reference_b49###; Ma et al. 2022  ###reference_b42###). These approaches highlight the use of specialized models like SparseConv (Choy, Gwak, and Savarese 2019  ###reference_b13###) for efficiently handling sparse voxel data, and Transformer-based models (Guo et al. 2023a  ###reference_b21###; Zhang et al. 2023b  ###reference_b76###) such as Point-MAE (Pang et al. 2022  ###reference_b44###), Point-M2AE (Zhang et al. 2022c  ###reference_b73###) and Point-BERT (Yu et al. 2022  ###reference_b67###) for leveraging self-supervised learning paradigms.\nMoreover, the integration of image-language models like CLIP (Radford et al. 2021  ###reference_b50###) into 3D shape understanding represents a significant trend (Zhang et al. 2022d  ###reference_b74###; Zhu et al. 2023  ###reference_b79###; Zeng et al. 2023  ###reference_b69###; Huang et al. 2023  ###reference_b29###; Liu et al. 2024  ###reference_b38###; Zhang, Cao, and Wang 2024  ###reference_b77###; Chen et al. 2023  ###reference_b9###; Wang, Chen, and Dou 2021  ###reference_b61###; Zhang et al. 2023a  ###reference_b75###; Zhu et al. 2024  ###reference_b78###). Models are trained to align 3D shape embeddings with CLIP\u2019s language and/or image embeddings through multimodal contrastive learning (Yuan et al. 2021  ###reference_b68###; Ding et al. 2023  ###reference_b18###; Ha and Song 2022  ###reference_b24###; Hegde, Valanarasu, and Patel 2023  ###reference_b25###; Hong et al. 2022  ###reference_b27###; Huang et al. 2024  ###reference_b28###; Jatavallabhula et al. 2023  ###reference_b30###; Chen et al. 2024  ###reference_b8###; Liang et al. 2022  ###reference_b37###; Liu et al. 2023  ###reference_b39###; Zhang et al. 2023b  ###reference_b76###). This allows for zero-shot 3D classification and improves the robustness of shape representations. Notably, advancements such as ULIP (Xue et al. 2023a  ###reference_b65###, b  ###reference_b66###), I2P-MAE (Zhang et al. 2023b  ###reference_b76###), and OpenShape (Liu et al. 2024  ###reference_b38###) have sought to refine this approach by optimizing the distillation of CLIP features into 3D representations and expanding training datasets for more generalizable learning outcomes.\n3D Mixing-based Augmentation.\nIn the realm of 3D mixing-based methods, significant strides have been made to enhance the diversity and quality of augmented point cloud data. Traditional techniques primarily involved simple transformations such as rotation, scaling, and jittering at the point level (Ren, Pan, and Liu 2022  ###reference_b52###; Qi et al. 2017a  ###reference_b46###, b  ###reference_b47###; Goyal et al. 2021  ###reference_b20###). However, recent innovations have introduced more sophisticated methods that preserve or even enhance the structural integrity of point clouds while introducing variability. For instance, PointAugment (Li et al. 2020  ###reference_b36###) optimizes both enhancer and classifier networks to generate complex samples, while techniques like Mixing-based augmentation (Chen et al. 2020b  ###reference_b12###; Zhang et al. 2022b  ###reference_b71###; Wang et al. 2024  ###reference_b62###; Lee et al. 2021  ###reference_b33###) employ strategies from the 2D domain, such as optimal linear interpolation and rigid transformations, to mix multiple samples effectively.\nFurthermore, the advent of Transformer-based methods and attention mechanisms in point cloud processing has opened new possibilities for data augmentation. PointWOLF (Kim et al. 2021  ###reference_b32###) introduces multiple weighted local transformations, and PointMixSwap (Umam et al. 2022  ###reference_b58###) utilizes an attention-based method to swap divisions across point clouds, adding a layer of complexity and diversity. Additionally, with the development of PointPatchMix (Wang et al. 2024  ###reference_b62###), point cloud mixing occurs at the patch level, which can generate more realistic data with the self-attention mechanism.\n###figure_2###"

This process involves first passing each input through the network independently to extract their respective features. Specifically, the first input is fed into the network, which processes it and extracts its feature vector . Similarly, the second input is also passed through the network, resulting in the extraction of its feature vector . Then the features are combined using a mixing operation to create a new, combined feature vector , which can be expressed as:\nInput-level mixing.\nFor input-level mixing, we follow PointCutMix (Zhang et al. 2022b  ###reference_b71###), which generates a new training point cloud  from a pair of point clouds  and .\nThe combination process of input-level augmentation is defined as follows:\nwhere  is the mixed point cloud,  indicates which sample each point belongs to,  represents element-wise multiplication, and  is sampled from a beta distribution . This implies that  points are selected from , and  points are selected from .\nFeature-level mixing operates on the encoded feature vectors, inducing implicit changes in the high-dimensional space. This allows for efficient data augmentation under cross-modal conditions, ensuring consistency of the augmented features across different modalities. In contrast, input-level augmentation directly manipulates the raw data, generating concrete and intuitive mixed samples. These realistic samples, which are both challenging and diverse, help the model better understand 3D shapes in downstream tasks. MM-Mixing combines these two augmentation strategies, achieving dual enhancement between raw data and latent features, thereby significantly improving the model\u2019s generalization ability."

Initially, point clouds are fed into the trainable point cloud Feature Mixing Encoder (FM-Encoder) to obtain 3D mixed feature embeddings. Concurrently, corresponding images and textual descriptions are processed through the frozen image and text Feature Mixing Encoders (FM-Encoders) to extract image and text mixed feature embeddings. These extracted 3D, image, and text features are then combined to mixed feature triplets. Employing a contrastive learning objective, the mixed 3D features are aligned with the image and text mixed features. This encourages the point cloud Feature Mixing Encoder (FM-Encoder) to learn a feature space that is consistent with the representations of the frozen encoders from other modalities, enhancing its ability to discriminate between different 3D objects. The Stage 1 corresponding contrastive loss  is calculated as:\nwhere  is the number of mixed features in a batch,  is a learnable temperature, and ,  denote normalized projected features of the mixed features of point clouds, images, and text respectfully. Because the image encoder and text encoder are frozen, we extract and cache the features before training for acceleration.\nIn the second stage, We initialize a new trainable 3D encoder. All Feature Mixing Encoders (FM-Encoders) remain frozen in this stage. Then we introduce a mixed point cloud input to further refine the 3D feature representations. Two input point clouds are selected and processed using farthest point sampling (FPS) and point-level mixing to create a novel mixed point cloud. The mixed point cloud is input to the new trainable 3D encoder to obtain mixed 3D feature embeddings. Simultaneously, the frozen Feature Mixing Encoders (FM-Encoders), are used to extract mixed features from their respective inputs. Using a contrastive learning objective, the 3D features of the mixed point cloud are aligned with the mixed features from the frozen encoders, ensuring that the new 3D encoder learns robust and discriminative mixed feature representations from different modalities. The Stage 2 contrastive loss  is calculated as:\nwhere  denotes normalized projected features of the mixed point clouds .\nBy leveraging these two stages, the MM-Mixing training pipeline fully exploits the complementary advantages of image and text encoders, integrating multi-modal information to develop a 3D encoder capable of producing highly discriminative features. In the first stage, the point cloud-image-text feature-level mixing ensures the consistency of augmented features across different modalities, facilitating the 3D encoder\u2019s cross-modal understanding. The second stage introduces input-level mixing, providing a vast array of complex and realistic samples that enhance the 3D encoder\u2019s generalization ability. Under the constraints of contrastive learning, MM-Mixing maintains the consistency between the features of the mixed point clouds and the mixed features of the point clouds."

Specifically, the \u201dShapeNet\u201d training set is composed entirely of triplets from the ShapeNetCore dataset, which includes 52,470 3D shapes along with their associated images and text descriptions. The comprehensive \u201dEnsembled\u201d dataset includes a total of 875,665 triplets, encompassing data from all four datasets, thereby providing a rich source of varied 3D shapes and their corresponding images and texts.\nEvaluation datasets.\nFor the evaluation of our model, we use a set of datasets that ensures a thorough assessment across different types of 3D data. The Objaverse-LVIS dataset (Deitke et al. 2023  ###reference_b16###), which is part of our evaluation, contains an extensive variety of categories with 46,832 high-quality shapes distributed across 1,156 LVIS (Gupta, Dollar, and Girshick 2019  ###reference_b23###) categories, offering a diverse and challenging environment for testing.

This task presents a considerable challenge for the model, requiring it to exhibit robust knowledge generalization, deep understanding of 3D shapes, and efficient cross-modal alignment.\nWe conduct extensive experiments to validate the effectiveness and robustness of our proposed MM-Mixing on three benchmark datasets: ModelNet40, ScanObjectNN, and Objaverse.\nAs shown in Table 1  ###reference_###, MM-Mixing consistently outperforms state-of-the-art methods under the same configurations (e.g., pre-trained datasets, training epochs, 3D backbones) and enhances the performance of various 3D models across all datasets. For instance, when pre-trained on ShapeNet, MM-Mixing boosts the accuracy of Point-BERT from 51.3% to 61.9% on the real-world dataset ScanObjectNN, even surpassing the 52.2% achieved by OpenShape pre-training on the Ensembled dataset. It indicates that MM-Mixing makes full use of limited multi-modal data to improve the model\u2019s understanding of 3D shapes and shows strong performance in handling complex noise interference.\nMoreover, on the challenging long-tail dataset, Objaverse, Point-BERT pre-trained with MM-Mixing achieves the accuracy of 51.4%, outperforming OpenShape\u2019s 46.8%. Another 3D backbone, SparseConv, also showed a 2.8% improvement in accuracy with our pre-training method. It indicates that existing 3D encoders can be easily incorporated into MM-Mixing framework, leading to a significant enhancement in 3D shape understanding.\nWhen the pre-training data is expanded from ShapeNet to a larger Ensembled dataset, the performance gains from MM-Mixing are slightly diminished. However, it still provides consistent accuracy gains to the models, underscoring the effectiveness of MM-Mixing on large-scale datasets."

All results are the classification accuracy (%) of SparseConv pre-trained on ShapeNet.\nMixing levels in alignment.\nWe investigate the impact of different mixing levels, including Feature-level Mixing (FM), Input-level Mixing (IM), and their combination (FM+IM). Compared to the baseline without mixing, all three strategies consistently improve the performance across all datasets. In Table 3  ###reference_###, Feature-level Mixing (FM) and Input-level Mixing (IM) individually contribute to the performance gains, and their combination (FM+IM) further improves the results. It confirms that the two mixing levels complement each other: Feature-level Mixing (FM) ensures cross-modal consistency in the feature latent space, while Input-level Mixing (IM) refines the realistic point cloud representation with challenging samples. Together, they enhance the model\u2019s ability of 3D understanding.\nAlignment stages. As shown in Table 4  ###reference_###, we evaluate the effectiveness of our two-stage alignment design. Feature-level Mixing(FM) is first employed to align 3D features with their corresponding modalities. In the second stage, mixed point cloud inputs are introduced to further align the four kinds of mixed features across the three modalities. The other approach is to align the mixed features of two levels simultaneously in one stage. Compared to one-stage alignment, the two-stage alignment method can better utilize diverse mixed samples to enhance cross-modal consistency.\nModality loss functions. Our ablation studies on different modality loss functions are shown in Table 5  ###reference_###. The text loss  provides a strong foundation for learning 3D representations with semantic information, while the image loss  and point cloud loss  offer complementary visual and shape information, enhancing the model\u2019s performance. The combination of all three modality loss functions consistently achieves the best results across all datasets, demonstrating the effectiveness of our framework.\nTraining costs analysis. Notably, the epochs of one-stage methods are the same as the two-stage training epochs of MM-Mixing for a fair comparison. Both 3D encoders are trained independently for the duration of one stage without shared weights. The experimental results demonstrate that the performance gains of MM-Mixing primarily stem from our mixing-based alignment framework, and the two-stage training framework further enhances the effectiveness of dual-level mixing. Moreover, for previous methods like OpenShape, adding additional training costs (e.g. training time and training parameters) does not significantly improve the performance of the 3D backbone (See Appendix for more details)."

Additionally, it can leverage detailed features (e.g. the presence of a drawer) to prevent misidentifying a table as a desk. It can be confirmed that MM-Mixing enhances model performance in 3D object recognition, particularly in scenarios with confusing samples and noise interference.\nCross-modal 3D shape retrieval.\nThe visualization in Figure 4  ###reference_### illustrates the superior performance of our method, MM-Mixing, compared to OpenShape in various cross-modal retrieval tasks. For PC-to-PC retrieval, MM-Mixing demonstrates a finer capture of shape details, as seen with the more accurate symmetrical guitar shape. In Image-to-PC retrieval, our method excels in preserving color details, which can retrieve more rational and approximate point clouds, such as the cake example.

In this context, the contribution of the dual-level mixed alignment method might be questioned.\nTo address this, we conducted a comprehensive analysis of the relationship between training costs and model performance, focusing on pre-trained model parameters and pre-training epoch, as shown in Table 6  ###reference_###.\nOur findings demonstrate that MM-Mixing consistently outperforms OpenShape across all datasets, irrespective of the pre-training configuration. Notably, when pre-training epochs are set to 1000, MM-Mixing achieves superior performance with only 41.3M parameters compared to OpenShape, which requires twice the number of parameters. This suggests that the core of MM-Mixing\u2019s enhanced 3D understanding capability lies in its mixed-based alignment method, a feature absent in OpenShape.\nFurthermore, our results indicate that the two-stage pre-training approach yields more substantial performance gains for MM-Mixing compared to the single-stage framework. This improvement can be attributed to the enhanced consistency of the dual-level mixing process. These findings underscore the significance of our proposed method in advancing 3D understanding capabilities.\nZero-shot 3D classification on ScanObjectNN. To further validate the effectiveness of MM-Mixing in enhancing the generalization ability of 3D representation learning models, we conduct zero-shot classification experiments on the real-world ScanObjectNN (Uy et al. 2019  ###reference_b59###) dataset. As shown in Table 7  ###reference_###, MM-Mixing significantly improves the performance of both SparseConv(Xue et al. 2023a  ###reference_b65###) and Point-BERT. For SparseConv, MM-Mixing boosts the average accuracy from 51.4% to 62.0%, achieving an improvement of 10.6 percentage points. Similarly, for Point-BERT, MM-Mixing enhances the average accuracy from 48.5% to 61.6%, resulting in an improvement of 13.1 percentage points.\nNotably, MM-Mixing brings improvements in most object categories. For SparseConv, all categories except chair and toilet witness accuracy gains, with the most significant improvements in the display and pillow categories, reaching 25.5 and 29.5 percentage points, respectively. For Point-BERT, all categories except bag experience performance enhancements, with the pillow category showcasing the most remarkable improvement of 53.2 percentage points.\nHowever, some categories remain challenging. For instance, the cabinet category exhibits extremely low accuracy (below 5%) in all cases, indicating that this category may be particularly difficult to recognize and require further exploration of alternative strategies to boost its performance.\nComparing the two 3D backbones, although Point-BERT initially underperforms SparseConv, MM-Mixing elevates Point-BERT\u2019s performance to a level comparable to SparseConv (61.6% vs. 62.0%). This observation reinforces the notion that it may be particularly well-suited for Transformer-based models like Point-BERT.\nIt is worth noting that MM-Mixing leads to performance degradation in a few categories. For example, in SparseConv, the chair and toilet categories experience a drop of 3.8 and 1.3 percentage points, respectively. This suggests that MM-Mixing may have negative impacts on certain categories, warranting further investigation into the underlying reasons and the development of targeted improvement strategies.\n###figure_5### The impact of the number of FC layers.\nTable 8  ###reference_### provides a comprehensive analysis of the impact of varying the number of fully connected (FC) layers on the performance of linear probing in different pre-training and evaluation scenarios.\nWhen pre-trained on ShapeNet (Chang et al. 2015  ###reference_b7###), the SparseConv model shows a progressive improvement in performance on ModelNet40 (Wu et al. 2015  ###reference_b64###) and ScanObjectNN datasets as the number of FC layers increases from 1 to 3. Specifically, the optimal performance on ModelNet40 (90.6%) and ScanObjectNN subsets (OBJ-BG: 86.6%, OBJ-ONLY: 87.1%, PB-T50_RS: 75.5%) is achieved with two FC layers, indicating that a moderate complexity in the FC layer structure can yield significant gains.\nFor the Point-BERT model pre-trained on ShapeNet, an increase in the number of FC layers consistently enhances performance across all datasets, with the highest accuracy observed at three layers (ModelNet40: 92.0%, OBJ-BG: 89.3%, OBJ-ONLY: 89.0%, PB-T50_RS: 78.4%). This suggests that Point-BERT benefits more substantially from deeper FC layers compared to SparseConv.\nIn the case of the ensembled pre-training dataset, similar trends are observed. The SparseConv model achieves its best performance with three FC layers (ModelNet40: 91.8%, OBJ-BG: 88.0%, OBJ-ONLY: 87.3%, PB-T50_RS: 79.0%), while the Point-BERT model significantly outperforms with three FC layers as well (ModelNet40: 93.4%, OBJ-BG: 90.4%, OBJ-ONLY: 89.3%, PB-T50_RS: 83.2%). The results indicate that ensembling pre-training data and increasing the FC layer depth synergistically enhance the model\u2019s ability to generalize and accurately classify 3D objects.\nOverall, our findings underscore the importance of optimizing the FC layer depth in linear probing to achieve superior model performance, with Point-BERT demonstrating a greater propensity for performance improvement with increased layer depth compared to SparseConv.\n###figure_6### ###figure_7### ###figure_8###"

Since the MLu performance depends on accurately approximating the conditional distributions, we focus on devising a synthetic data generation method based on conditional distribution estimation. We introduce MaCoDE by redefining the consecutive multi-class classification task of Masked Language Modeling (MLM) as histogram-based non-parametric conditional density estimation. Our approach enables the estimation of conditional densities across arbitrary combinations of target and conditional variables. We bridge the theoretical gap between distributional learning and MLM by demonstrating that minimizing the orderless multi-class classification loss leads to minimizing the total variation distance between conditional distributions. To validate our proposed model, we evaluate its performance in synthetic data generation across 10 real-world datasets, demonstrating its ability to adjust data privacy levels easily without re-training.

+            "text": "There are two main objectives in synthetic tabular data generation: (1) preserving the statistical characteristics of the original dataset and (2) achieving comparable machine learning utility (MLu) to the original dataset. In this paper, our focus is on generating synthetic data with high MLu performance. Note that achieving high statistical fidelity does not guarantee high MLu performance (Hansen et al. 2023  ###reference_b18###).\nGiven that MLu performance depends on accurately approximating conditional distributions, we focus on developing a synthetic data generation method based on conditional distribution estimation. However, two important properties of tabular data must be considered: () tabular data can consist of mixed types of data (Borisov et al. 2021  ###reference_b4###; Shwartz-Ziv and Armon 2022  ###reference_b49###), and () the tabular data does not have an intrinsic ordering among columns (Gulati and Roysdon 2023  ###reference_b16###).\n()\nConsidering the heterogeneous nature of tabular data and aiming to develop a method that addresses the challenges of modeling diverse distributions of continuous columns, we employ histogram-based non-parametric conditional density estimation through a multi-class classification task (Li, Bondell, and Reich 2019  ###reference_b31###). This approach enables us to apply the classification loss uniformly across all types of columns. Since the histogram-based approach is theoretically valid only when continuous variables have bounded supports (Wasserman 2006  ###reference_b57###; Li, Bondell, and Reich 2019  ###reference_b31###), we transform continuous columns using the Cumulative Distribution Function (CDF) and constrain their values to the interval  (Li et al. 2021  ###reference_b30###; Fang et al. 2022  ###reference_b13###).\n()\nTo learn the arbitrary generation ordering of columns, we utilize the Masked Language Modeling (MLM) approach (Devlin et al. 2019  ###reference_b10###). By employing a masking scheme and the BERT model architecture, our proposed model enables the estimation of conditional densities across arbitrary combinations of target and conditional variables (Ghazvininejad et al. 2019  ###reference_b15###; Ivanov, Figurnov, and Vetrov 2019  ###reference_b21###; Naz\u00e1bal et al. 2020  ###reference_b41###). (Gulati and Roysdon 2023  ###reference_b16###) proposed a similar method called TabMT, however, TabMT faces challenges in distributional learning because it relies on predicting the K-means cluster index of masked entries. Our approach contrasts with existing auto-regressive density estimators, which generate data in a fixed column order (Hansen 1994  ###reference_b17###; Kamthe, Assefa, and Deisenroth 2021  ###reference_b24###; Letizia and Tonello 2022  ###reference_b29###). Additionally, (Germain et al. 2015  ###reference_b14###; Papamakarios, Pavlakou, and Murray 2017  ###reference_b43###) are also able to estimate conditional densities but differ from our approach by masking the model weights rather than the input.\nTherefore, our proposed method redefines the consecutive multi-class classification task of MLM as histogram-based non-parametric conditional density estimation. We term our proposed model MaCoDE (Masked Conditional Density Estimation). The main contribution of our work is bridging the theoretical gap between distributional learning and the consecutive minimization of the multi-class classification loss within the MLM approach.\nSpecifically, we demonstrate that minimizing the orderless multi-class classification loss, when combined with the CDF transformation, provides theoretical validity for minimizing the discrepancy between conditional distributions in terms of total variation distance. This implies that we do not need to consider the ordering of bins, which could otherwise serve as a useful inductive bias. Note that, in the natural language domain, previous attempts to interpret MLM as distributional learning have been somewhat limited, relying on pseudo-likelihood or Markov random fields (Ghazvininejad et al. 2019  ###reference_b15###; Wang and Cho 2019  ###reference_b56###; Salazar et al. 2019  ###reference_b48###; Ng, Cho, and Ghassemi 2020  ###reference_b42###; Hennigen and Kim 2023  ###reference_b19###).\nWe substantiate the effectiveness of our proposed method by evaluating its performance in synthetic data generation across 10 real-world tabular datasets, demonstrating its capability to adjust data privacy levels easily without re-training. Given that masked input tokens in MLM can be viewed as missing data, we also assess our model\u2019s effectiveness in handling training datasets with missing values. Moreover, as our proposed model estimates the conditional distribution while accommodating arbitrary conditioning sets, it can address various missingness patterns - an essential capability for generating samples and performing multiple imputations (van Buuren 2012  ###reference_b54###; Ivanov, Figurnov, and Vetrov 2019  ###reference_b21###; Naz\u00e1bal et al. 2020  ###reference_b41###). Consequently, we further validate our method\u2019s effectiveness by evaluating its performance in multiple imputations across various missing data mechanisms."

Our proposed method integrates histogram-based non-parametric conditional density estimation and the MLM-based approach while bridging the theoretical gap between distributional learning and the consecutive multi-class classification task of MLM. Although our primary goal is to generate synthetic data with high MLu, we empirically demonstrate that we achieve high joint statistical fidelity and MLu simultaneously. Furthermore, empirical experiments validate that our proposed model can generate high-quality synthetic tabular datasets in terms of MLu even when incomplete training datasets are given.\nAlthough MaCoDE demonstrates the ability to perform \u2018arbitrary\u2019 conditional density estimation by accommodating various combinations of conditioning sets and target variables, and despite empirical results showing its effectiveness in handling diverse distributions of continuous columns and generating high-quality synthetic data, the model has theoretical limitations. Specifically, it is valid under Lipschitz continuity (Assumption 2  ###reference_umption2###). Addressing the limitation of accommodating a broader range of continuous distributions is an important direction for future work."

+    "abstract": "Sim-to-real transfer presents a difficult challenge, where models trained in simulation are to be deployed in the real world. The distribution shift between the two settings leads to biased representations of the dynamics, and thus to suboptimal predictions in the real-world environment. In this work, we tackle the challenge of sim-to-real transfer of reinforcement learning (RL) agents for coverage path planning (CPP). In CPP, the task is for a robot to find a path that covers every point of a confined area. Specifically, we consider the case where the environment is unknown, and the agent needs to plan the path online while mapping the environment. We bridge the sim-to-real gap through a semi-virtual environment, including a real robot and real-time aspects, while utilizing a simulated sensor and obstacles to enable environment randomization and automated episode resetting. We investigate what level of fine-tuning is needed for adapting to a realistic setting, comparing to an agent trained solely in simulation. We find that a high inference frequency allows first-order Markovian policies to transfer directly from simulation, while higher-order policies can be fine-tuned to further reduce the sim-to-real gap. Moreover, they can operate at a lower frequency, thus reducing computational requirements. In both cases, our approaches transfer state-of-the-art results from simulation to the real domain, where direct learning would take in the order of weeks with manual interaction, that is, it would be completely infeasible.",

+            "text": "A practical limitation for training machine learning models is the need for large amounts of real-world data, which is tedious and time-consuming to collect. In particular, training reinforcement learning (RL) agents for robotics from scratch requires access to the robot for the full duration of the training process. Meanwhile, during the early training phase, the agent is more likely to make mistakes that may damage the hardware or require human supervision for resetting the episodes. Instead, learning in simulation presents an attractive alternative (Jonnarth, Zhao, and Felsberg 2024  ###reference_b18###). However, due to differences in the dynamics between the simulation and the real world, transferring a model from simulation to reality is challenging. Prior work reduce the sim-to-real gap by improving the simulation, e.g. by injecting realistic noise (Kaufmann et al. 2023  ###reference_b19###; Zhao et al. 2020  ###reference_b39###), applying domain randomization (Muratore et al. 2021  ###reference_b22###; Tobin et al. 2017  ###reference_b29###), or through meta learning (Arndt et al. 2020  ###reference_b3###; Nagabandi et al. 2019  ###reference_b23###). Our goal is to transfer, for the task of coverage path planning (CPP), the state-of-the-art performance of models trained in simulation to real environments, by fine-tuning in a realistic setting.\nIn CPP, the task is to find a path that covers all of the free space of an environment. If the environment is known, an optimal path can be planned offline (Huang 2001  ###reference_b15###). If it is unknown, the path has to be planned online during mapping of the environment, e.g. by a robot, and an optimal path cannot be found in the general case (Galceran and Carreras 2013  ###reference_b9###). CPP has found its uses in many robotic applications, such as lawn mowing (Cao, Huang, and Hall 1988  ###reference_b5###), vacuum cleaning (Yasutomi, Yamada, and Tsukamoto 1988  ###reference_b36###), search-and-rescue (Jia et al. 2016  ###reference_b17###), and exploration (Xu et al. 2022  ###reference_b33###).\nWhen training reinforcement learning models in real time on physical robots, additional considerations need to be accounted for compared to training in simulation. (1) There exists a mismatch between the real and simulated robot kinematics, dynamics, and sensing, such as slippage and noisy localization. This leads to different transition probabilities in the real world, where the predicted actions based on simulation may be suboptimal. (2) Due to inertia and latencies in the system, the dynamics are non-Markovian (Haarnoja et al. 2018b  ###reference_b13###). This violates the common assumption that the Markov property holds. (3) Since the robot keeps moving during the various computations in the training process, the state observed by the agent is not perfectly aligned with the true state. This introduces a delay, where the agent predicts actions based on outdated observations of the environment. In this work, we address these problems.\nTo smoothen the transition into the real world, we use a real robot in a semi-virtual environment, utilizing a highly accurate positioning system in an indoor planar setting, with a simulated sensor and obstacles. This introduces the previously mentioned real-time aspects of reinforcement learning in a controlled manner, while allowing flexibility in utilizing automated episode resetting and varying training environments without having to physically construct them. By fine-tuning and evaluating CPP policies in this semi-virtual setting, we can draw conclusions about how we expect similar policies to generalize to fully realistic environments.\nTo reduce latency in the training process, we perform model updates in parallel with the action and state selection (Yuan and Mahmood 2022  ###reference_b38###), and perform all computations on on-board hardware. We utilize soft actor-critic learning (Haarnoja et al. 2018a  ###reference_b12###) for its sample efficiency and its efficacy on continuous action spaces. To account for the non-Markovian dynamics in a lightweight manner, we include past actions in the observation space. Finally, to reduce the mismatch between the simulated and real kinematics, we measure the real-world linear and angular accelerations as well as action delay, and incorporate them into the simulation. We find that a high inference frequency enables first-order Markovian policies to transfer to a real setting. By introducing delays and action observations, higher order Markovian models can be fine-tuned to further reduce the sim-to-real gap. Moreover, these models can operate at a lower frequency, thus reducing the computational requirements for deployed systems.\nOur contributions can be summarized as follows:\nWe propose to divide the sim-to-real problem into two steps with an intermediate case of a real robot in a virtual environment.\nWe show that this division enables a transfer of state-of-the-art RL policies for CPP from simulation to the real robot.\nWe propose to perform data collection and model updates in parallel, which enables real-time fine-tuning online without a separate system or stopping the robot for model updates.\nWe evaluate the effects of inference frequency and fine-tuning on the performance of the real robot."

We summarize the related work below.\nCoverage path planning methods can roughly be categorized as planning-based or learning-based. Planning-based methods include decomposition methods, which divide the area into cells based on e.g. boustrophedon cellular decomposition (BCD) (Choset and Pignon 1998  ###reference_b7###) or Morse decomposition (Acar et al. 2002  ###reference_b1###), where each cell is covered with a pre-defined pattern. Grid-based methods, such as Spiral-STC (Gabriely and Rimon 2002  ###reference_b8###) and the backtracking spiral algorithm (BSA) (Gonzalez et al. 2005  ###reference_b10###), discretize the area into even smaller cells, e.g. squares, with a similar size to the agent. Then, a path is planned based on motion primitives connecting adjacent cells, i.e. to move up, down, left, or right on the grid, such that each cell is visited at least once. Frontier-based methods plan a path to a chosen point on the frontier, i.e. on the boundary between covered and non-covered regions. The choice of frontier point can be based on different aspects, such as the distance to the agent (Yamauchi 1997  ###reference_b34###), the path of a rapidly exploring random tree (RRT) (Umari and Mukhopadhyay 2017  ###reference_b30###) or the gradient in a potential field (Yu et al. 2021  ###reference_b37###). Learning-based methods apply machine learning techniques, typically in combination with planning-based methods, to find coverage paths. Reinforcement learning is the most popular paradigm due to the sequential nature of the task. Chen et al. (2019  ###reference_b6###) use RL to find the order in which to cover the cells generated by BCD. Discrete methods (Piardi et al. 2019  ###reference_b25###; Kyaw et al. 2020  ###reference_b20###) use RL to learn which motion primitives to perform. RL has also been combined with frontier-based methods, either for predicting the cost of each frontier point (Niroui et al. 2019  ###reference_b24###), or for learning the control signals to navigate to a chosen point (Hu et al. 2020  ###reference_b14###). In contrast, Jonnarth, Zhao, and Felsberg (2024  ###reference_b18###) propose to learn continuous control signals end-to-end from a built map and sensor data. In our work, we adopt this approach to transfer agents from simulation to a real setting. To the best of our knowledge, we are the first to do so for end-to-end RL policies in CPP.\nSim-to-real transfer. Transferring from simulation to the real world is challenging due to mismatch in both sensing and actuation (Zhao, Queralta, and Westerlund 2020  ###reference_b40###). Prior work has approached this challenge by different means. Domain randomization has been utilized to randomize physical parameters in simulation, such as mass and joint damping (Muratore et al. 2021  ###reference_b22###), or to randomize textures and lighting in the image domain (Tobin et al. 2017  ###reference_b29###). Other works introduce perturbations in the sensing and actuation (Zhao et al. 2020  ###reference_b39###). Meta learning methods aim to quickly adapt to new unseen tasks from a wide variety of training task, such as adapting to the real world from simulation (Arndt et al. 2020  ###reference_b3###; Nagabandi et al. 2019  ###reference_b23###). Another approach is to learn from expert demonstrations through imitation learning (Yan et al. 2017  ###reference_b35###), which has previously been applied to coverage path planning (Hu et al. 2020  ###reference_b14###). When it comes to robot control, Niroui et al. (2019  ###reference_b24###) deploy an RL policy for CPP trained in simulation on a differential drive robot without fine-tuning. The policy predicts the next frontier node, where a separate non-learned module navigates to it, thus being less affected by misaligned kinematics between simulation and reality. Kaufmann et al. (2023  ###reference_b19###) transfer a lightweight RL control policy using a pre-trained perception system for first-person-view drone racing, utilizing empirical noise models to improve the fidelity of the simulator. They collect perception and dynamics residuals in the real world based on a highly accurate positioning system, which they use to augment the simulation. In contrast to these works, we fine-tune our model online in the real world.\nOnline RL. Compared to turn-based and simulated environments, where the time for action selection and policy updates are assumed to be zero and the next state can be advanced to in an instant, online RL in the real world presents new challenges where these assumptions do not hold. The core idea in the literature for accounting for this discrepancy is to parallelize aspects of the environment interactions and the model training. Bakker et al. (2006  ###reference_b4###) explore quasi-online reinforcement learning, where a model of the environment is built online and in parallel to training the policy based on the built environment model. Ramstedt and Pal (2019  ###reference_b28###) propose real-time reinforcement learning, where the action selection occurs in parallel with the state selection. Concretely, given the current state and action to be taken, the agent and environment compute the next set of state and action concurrently. This approach takes into account the time for action selection by delaying the observed state by one time step. However, it does not consider the time for model updates, which is typically much larger. Other works (Haarnoja et al. 2019  ###reference_b11###; Wang, Vasan, and Mahmood 2023  ###reference_b31###) distribute the model training for soft actor-critic (SAC) (Haarnoja et al. 2018a  ###reference_b12###) to a separate system, while performing only the lightweight action and state selections on the on-board target hardware. This allows the data collection to be executed independently from the model updates, where the policy and replay buffer are periodically synchronized. Yuan and Mahmood (2022  ###reference_b38###) employ a similar approach, but they run everything on a single edge device. They divide the training process into separate processes for the action selection, state selection, batch sampling, and gradient computation. We follow this approach. However, in our experimental setup, the action selection and batch sampling were much faster than the state selection and gradient computations, so we only use two threads in order to reduce complexity and communication overhead."

The task is for the agent to simultaneously map the a priori unknown environment geometry, while finding a path that covers all of its free space. A point in the free space is considered covered when the distance to the center of the agent is less than the coverage radius , and the point is in the field-of-view of the agent. The coverage radius may be smaller or equal to the agent radius  as in the lawn mowing problem, or larger than  as in the exploration problem. For mapping the environment, the agent is equipped with a ranging sensor, which is used to add obstacle detections to a global map.\nWe formulate the task as a partially observable Markov decision process (POMDP), consisting of an agent that predicts actions in an environment such as to maximize a reward function. In discrete time steps , the agent predicts actions  according to policy , based on observations  of the state . The policy is a neural network that predicts continuous control signals  for the agent. Subsequently, the agent receives a new observation and reward  from the environment, where . The goal for the agent is to maximize the expected discounted reward , with discount factor .\nIn our particular problem, the state  includes the full environment geometry with all obstacles, the set of points that have been covered, as well as the pose of the agent. However, the agent only has information about what it has observed, so the observation  consists of the part of the environment that has been mapped until time step , along with covered points, agent pose, and sensor data.\nIn the setting with a real robot, the first order Markovian property is not fulfilled, due to the dynamics including inertia and momentum. The usual approach to augment previous states in the current one becomes infeasible if the motion is implicitly represented by the agent-centered environment maps. Thus higher-order effects lead to model errors that need correction in subsequent steps."

In order to represent the environment, covered regions and detected obstacles are recorded in the form of global grid-like 2D maps. To represent large regions as input to the agent, multiple local maps are used with varying scales, each with the same grid size. The maps contain increasingly larger crops of the local area, with decreasing resolution. The finest scale shows detailed information near the agent, while the coarsest scale contains the largest area at a low resolution. In addition to coverage and obstacle maps, multi-scale frontier maps are also recorded. The frontier is the boundary between covered and non-covered space, which allows the agent to easily plan paths towards non-covered regions. All maps are represented as egocentric maps, that is, they are aligned such that the agent is in the center facing upwards.\nSensor observation. To detect obstacles, the agent is equipped with a simulated light detection and ranging (lidar) sensor, which measures distances in fixed angles relative to the agent. When obstacles are detected, they are added to the obstacle map based on the known global pose of the agent. The lidar distances are included in the observation space after normalization to .\nAction space. We consider a differential drive wheeled robot, which is controlled by two separately driven wheels. The agent predicts the linear and angular velocities  and  for the robot. In contrast to the cited work, we convert them to angular velocities  and  for the right and left wheels,\nwhere  is the wheel radius and  is the distance between the wheels.\nReward function. In addition to a coverage reward term, Jonnarth, Zhao, and Felsberg (2024  ###reference_b18###) found it necessary to include a total variation (TV) reward that penalizes variations in the coverage map, such as excessive boundaries. By reducing the total variation, the agent learns to cover the area in a more compact manner, reducing leftover holes in the coverage map, and thus, allows for complete coverage. In total, four reward terms are used: a coverage reward , a TV reward , a collision reward , and a constant reward . The coverage reward is written as\nwhere  is a scaling factor,  is the newly covered area,  is the maximum speed of the robot, and  is the time step size. The denominator is the largest possible area that can be covered in a time step and ensures that the reward is normalized to . The TV reward is written as\nwith scaling factor , where  is the coverage map at time , and  is the total variation\nFinally, the agent is penalized by a negative obstacle collision reward  on impact, and a constant negative reward  is given each time step. Each episode is terminated when a goal coverage has been reached, or after  consecutive steps without new ground being covered.\nModel architecture. To process the multi-scale maps together with the sensor data, a scale-grouped convolutional neural network (SGCNN) is used, which has shown to be superior to a standard CNN or MLP (Jonnarth, Zhao, and Felsberg 2024  ###reference_b18###). It consists of a map feature extractor , a sensor feature extractor , and a fusing module . The map feature extractor groups the maps by scale and processes them separately using grouped convolutions, while the sensor feature extractor and fusing module consist of fully connected layers. The control signal predictions are given by\nwhere , , and  are the multi-scale coverage, obstacle, and frontier maps respectively, and  is a vector of the observed normalized lidar distance measurements."

While this is feasible in simulation and turn-based environments where the environment can be paused during model updates and time can be advanced instantly to the next state after action selection, it is not practical for real-time robotic applications where the agent is trained online.\nIn this case, we need to wait after action selection to observe the next state, while the execution remains idle. After the environment interaction, a batch is sampled from the replay buffer, gradients are computed, and the model is updated. However, this takes time, which is not negligible, especially on low-performance edge devices and embedded systems. During the gradient update step, the robot keeps following its previous action. As a result, the agent ends up in a state which deviates from the recorded one used for action selection. Following previous work (Haarnoja et al. 2019  ###reference_b11###; Yuan and Mahmood 2022  ###reference_b38###), we perform the model updates in parallel with the data collection, utilizing computational resources which would otherwise remain idle while waiting for the next state.\n###figure_1### The training process can be divided into four main computational steps, where the respective measured times are given in Table 1  ###reference_###:\nGiven the current observation, we sample an action from the policy. This corresponds to a forward pass of the policy network.\nAfter sampling an action, the control signals are sent to the robot platform, and the new state is observed. In simulation, this would occur instantly, while in the real world we need to let time pass to observe how the action affected the environment. After state selection, the reward is computed, and the action, previous state, new state, and reward are added to the replay buffer.\nA training batch is sampled from the replay buffer.\nGradients are computed based on the training batch, and the model weights are updated. This is the most computationally intensive part.\nSince the action selection and batch sampling were fast compared to the state selection and gradient computations, we only use two threads to reduce overhead and complexity. Our computational graph is shown in Figure 1  ###reference_###, which consists of an environment interaction thread (top) and a model update thread (bottom).\nSince both threads interact with the replay buffer, we use a mutex to avoid conflicts. Luckily, the the environment interaction thread adds an entry at the end of the cycle, while the model update thread samples from it early, so the there is a low chance that they block each other.\nSince the model update thread modifies the weight tensors during a large portion of the runtime, i.e. both during the backward pass to update the gradients and during the optimizer step to update the parameters, a mutex is not feasible as it would block execution too often. Instead, we keep a copy of the model, which is only accessed by the model update thread. The weights are synchronized when both threads have finished.\nWith this approach, both the environment interaction and the model update can be performed multiple times before model synchronization. This is useful when the computation time for the model update exceeds that of the action and state selection. In this case, the number of environment interaction steps should be chosen to match the computation time for the model update. Meanwhile, if the model update is fast compared to the environment interaction, multiple updates can be performed during one environment interaction step, which was the case in our experiments.\nApart from the four main computational steps, the time for simulating the sensor, creating the observation, and synchronizing the weights results in additional overhead. This effectively becomes part of the action selection as the overhead delays the observed state, and results in an action delay."

However, this would make training and fine-tuning cumbersome as manual interaction would be required to supervise the training process. In order to fully automatically (continue to) train the system, we propose to use a semi-virtual setup, see Figure 2  ###reference_###. In this setup, we use the real robot with its kinematics and dynamics, but simulate its lidar sensor and obstacles, and localize the robot using a positioning system. The environment, including obstacles and coverage, e.g. from mowing, is visualized by a projection onto the ground.\nThe main purpose of using such an environment is to evaluate, in a controlled manner, the ability of the learning algorithm to generalize to a real robot in a real-time setting. Furthermore, the considered RL approach is robust to sensing and localization noise, and can be extended to the case of unknown pose, e.g. by estimating the pose using an off-the-shelf SLAM method (Jonnarth, Zhao, and Felsberg 2024  ###reference_b18###). Thus, using our semi-virtual environment, we can draw conclusions about how we expect similar policies to generalize to fully realistic settings.\n###figure_2### As mentioned, this semi-virtual setup enables fully automatic RL with the real robot. In particular, if the robot would drive towards one of the walls, both the robot and the environment can be moved back to the middle of the room. Furthermore, since we can automatically change or generate new environments each episode, we can train general CPP policies for completely unseen environments, and not just for a single fixed environment. Finally, the setup can also be used for fully automatic benchmarking of the learned model.\nTo further smoothen the sim-to-real gap, we improve the fidelity of the simulator by taking into consideration the latencies induced by inertia and action delay. We measure the maximum linear acceleration, maximum angular acceleration, and action delay of the real system, and include these aspects in the simulated kinematics and dynamics.\nTo account for higher-order Markovian dynamics, we include information from previous time steps in the observation space. While the common approach is to stack several previous observations (Haarnoja et al. 2019  ###reference_b11###; Mnih et al. 2013  ###reference_b21###), it is less feasible in our setting for multiple reasons. (1) Since the pose is embedded in the egocentric maps, rapid rotations significantly alter the observed state, making it difficult to learn the dynamics. (2) It significantly increases the model size and processing time, which are critical aspects for real-time applications. (3) It severely limits the replay buffer size, as the map observations are fairly large. Instead, we use a history of the previous actions (Haarnoja et al. 2019  ###reference_b11###; Mnih et al. 2013  ###reference_b21###), which is lightweight and avoids the listed problems, and should be sufficient for learning the dynamics of the robot. A benefit of using action observations instead of velocity estimates is that the estimates can be highly noisy. Furthermore, using action observations, the agent can learn to estimate the velocity if necessary."

In this experiment, the observation space does not include any previous actions, and the policy is trained for M steps in a simulated environment without a limit on the linear and angular accelerations, and does not include any action delay. We evaluate the policy in simulation and in the real environment before and after fine-tuning. Since this policy does not depend on the previous action sequence, we can run it at any frequency. We evaluate it at the training frequency and as fast as possible, i.e. without waiting during state selection, which was measured to 15 ms per time step.\nBy comparing coverage times between simulation and reality in Table 2  ###reference_###, we see that they are in the same ball park, where the real results are slightly worse at the lower frequency. This is expected due to differences in kinematics and other sources of error. When increasing the inference frequency, we observe faster coverage times, even surpassing the simulation results. This is likely the case due to the fact that the agent can update its actions faster and quickly adapt to errors. Thus, it can navigate more efficiently and produce a smoother pattern.\nHowever, after fine-tuning, we find that the performance degrades. Our hypothesis is that as the observation includes no higher-order information, the optimal action cannot be deduced. For example, if the robot completely changes the direction of rotation, it takes some time before the new rotation takes effect. The observation may not change much, while the optimal action does. Thus, the performance degrades initially, which may take a long time to recover from. Running the inference at a high frequency partly circumvents this problem, explaining the high performance of the model without fine-tuning. While we did not evaluate the fine-tuned policy on a lower frequency, we expect it to perform worse as in the non fine-tuning case.\n###figure_3### ###figure_4###"

Since the 10 actions correspond to specific points back in time, we keep the inference time step the same as during training.\nThe new model can learn higher-order Markovian dynamics, and in Table 3  ###reference_### we see that it transfers well when directly deployed from simulation, surpassing the first-order model for  coverage under this lower inference frequency. Again, the real results are somewhat worse compared to the simulation results, as expected. In Figure 3  ###reference_###, where we record the performance on a subset of the maps during fine-tuning, we observe that the performance degrades initially, but in contrast to the first-order model, the agent surpasses its original performance.  degrades heavily in the early stage, while  remains more or less constant. This suggests that the agent initially sacrifices long-term planning in favour of low-level control. After it has adapted to the low-level controls, then the long-term planning also improves.

The number of rotations were computed by summing the absolute differences in heading angle in every time step. Similar to the coverage time, both metrics degrade initially, and then improve over time, surpassing the initial performance. This shows that the agent finds a more efficient path after fine-tuning. It reduces the number of turns, which take time, while it overlaps its previous path less, thus reducing the total path length.\nIn total, the fine-tuning took roughly  hours, which is only a small fraction of the weeks it would have taken to train from scratch.

+            "text": "IEEE 802.11ax (Wi-Fi 6) marked a significant evolution milestone via the introduction of Multi-User (MU) communication modes (in contrast with legacy Single-User (SU) communication) for both Uplink (UL) and Downlink (DL) in tri-band (2.4/5/6 GHz) [1  ###reference_b1###]. For the Uplink, this implies the use of trigger-based OFDMA; in this article, we focus solely on DL Multi-User (MU) Multiple Input Multiple Output (MU-MIMO). Legacy Single-User MIMO (SU-MIMO) - the precursor to MU-MIMO - laid the groundwork by allowing transmission of multiple spatial streams from an access point (AP) equipped with multiple antennas to a single client device on downlink. With the proliferation of wireless client devices, a single Wi-Fi network access point (AP) can have multiple associated stations (STAs) [2  ###reference_b2###, 3  ###reference_b3###]. With multi-antenna clients 111However, the number of antennas at the AP always exceeds the number of antennas at a client., it is feasible via DL Transmit Beamforming (TxBF) at the AP to send multiple streams to multiple STAs simultaneously (DL MU-MIMO).\nA typical configuration [4  ###reference_b4###, 5  ###reference_b5###] such as Fig. 1  ###reference_### assumes an 8 x 8 AP (e.g., NetGear RAXE500) and 2 x 2 STAs (e.g., iPhone 15 and MacBook Air), implying that a single downlink transmission opportunity can potentially send a total of  spatial streams 222Note that Wi-Fi 5 (IEEE 802.11ac) included support for MU-MIMO but limited to 4 streams on only 5 GHz downlink operation; whereas Wi-Fi 6 supports up to 8-stream on 2.4/5/6 GHz uplink/downlink operations. to a selected sub-set of clients, e.g. each 2 streams to each selected four STAs. While DL SU-MIMO results in scaling\nof per-user throughput as a result of multi-stream transmission, its benefits are limited by the fact that most clients support either 1 or 2 spatial streams (i.e., a total of 2-stream transmissions in DL SU-MIMO in Fig. 1  ###reference_###). By contrast, it is evident that in dense overlapped network scenarios - such as the enterprise or residential cluster - DL MU-MIMO provides a natural pathway to increasing network efficiency (aggregate network throughput) by enabling simultaneous transmissions of multiple streams to multiple clients (i.e., a total of 8-stream transmissions in DL MU-MIMO in Fig. 1  ###reference_###), with appropriate choice of the user sub-set and TxBF to minimize inter-user/inter-stream interference.\n###figure_1### Despite the promise of MU-MIMO for improved network capacity via simultaneous transmission to multiple users on downlink333There exists an analogous feature for the uplink: trigger-based OFDMA whereby a  MHz channel may be shared synchronously by multiple users. However, consideration of UL OFDMA is beyond the scope of this article., real-world user testing has revealed significant challenges. A noticeable discrepancy exists between the theoretical speeds advertised by manufacturers who incorporate DL MU-MIMO and the actual throughput measured in specific conditions [6  ###reference_b6###, 7  ###reference_b7###, 8  ###reference_b8###]. An industry test report [9  ###reference_b9###] showed that turning on MU-MIMO resulted in 58% aggregate throughput loss compared to SU-MIMO when pairing 4 x 4 Broadcom-based router with 2 x 2 Qualcomm-based STAs. An earlier research study [10  ###reference_b10###] demonstrated that DL SU-MIMO achieves 16.8% to 42% higher aggregated throughput MU-MIMO based on a test of a commercial 4 x 4 MU-MIMO-capable 802.11ac 5 GHz radio with 1 x 1 Xiaomi Mi 4i smartphones. Such variation in results is attributable to various factors at play, including the complex interplay of channel state information (CSI) overhead, device capabilities and environmental (propagation) conditions as a function of user location. In this article, we chose the IEEE 802.11ax indoor channel model [11  ###reference_b11###], widely used by the industry and academia, for a foundational exploration of DL SU/MU-MIMO throughput. Specifically, as the selected sub-set of clients for MU-MIMO on downlink are closer to each other in dense networks, increased spatial correlation will lead to significant inter-user and inter-stream interference in DL MU-MIMO. Thus overall network throughput degrades unless counteracted by a combination of inter-user interference cancellation and user selection algorithms [12  ###reference_b12###, 13  ###reference_b13###]. Moreover, CSI overhead affects both SU and MU aggregate throughput; in particular, CSI overhead increases significantly with the dimensionality of MU-MIMO. In turn, this implies that any MU-MIMO design must carefully consider the issue of (optimal) channel sounding periodicity when confronted with channel time variations444Further consideration of this topic is beyond the scope of this article..\nThe lack of a sufficiently deep understanding of the interplay between the various underlying factors discussed has resulted in AP vendors turning off the DL MU-MIMO feature as default setting in their products, reflecting the current ambivalence surrounding DL MU-MIMO. The primary purpose of this article is therefore to provide new insights underlying the fundamental question: \u201cwhen should DL MU-MIMO be turned on/off\u201d as a function of the operational scenario. By a combination of analysis and computation/simulation, we attempt to answer the above question by\nIdentifying set of conditions where DL SU-MIMO outperforms MU-MIMO and vice-versa;\nProvide broad \u2018rules of thumb\u2019 regarding use of DL MU-MIMO in current/future Wi-Fi systems.\nThe rest of this article is organized as follows. Section II  ###reference_### introduces the impact of DL SU and MU CSI overhead differences on their effective channel capacity; In Section III  ###reference_###, we explore the impact of spatial correlation on the MU channel capacity under the IEEE 802.11ax indoor channel model. In Section IV  ###reference_###, a design guideline table for DL MU-MIMO is proposed by unifying the factors discussed in Section II  ###reference_### and III  ###reference_###. Finally, Section V  ###reference_### concludes this article."

As Fig. 2  ###reference_### shows, its channel sounding process consists of four major steps:\nThe beamformer begins the process by broadcasting a Null Data Packet Announcement (NDPA) frame, which is used to gain control of the channel and identify the intended beamformee.\nThe beamformer next transmits a Null Data Packet (NDP) to beamformee after a Short Interframe Space (SIFS). NDP is an empty frame that only contains the Physical Layer Protocol Data Unit (PPDU) header. The received NDP is used for channel estimation by analyzing the OFDM training symbols, called HE-LTF, whose length is a variable that depends on the number of spatial streams.\nFollowing receipt of the NDP, the beamformee responds with a BF feedback matrix in a compressed form. The BF feedback matrix instructs how the beamformer should steer the data frame to the beamformee with higher energy. Codebook information in the HE MIMO Control field provides the resolution schemes for compressing the BF feedback matrix.\nThe beamformer receives and recovers the compressed feedback matrix that is further used as the steering matrix to direct HE data transmissions toward the beamformee.\nBy contrast, DL MU-MIMO, indicated by codebook info 1 in the HE MIMO control field, follows the similar channel sounding protocols as the SU-MIMO, however, several major differences exist:\nNDPA frame format: A HE NDPA frame in MU-MIMO includes multiple STA Info fields, one for each beamformee, while the NDPA frame in SU-MIMO only carries a single STA Info field.\nBF Report Poll (BFRP) trigger frame: The compressed BF feedback in SU-MIMO comes right after the NDP. However, the beamformer in DL MU-MIMO must use a control frame - BFRP Trigger frame that instructs each beamformees to transmit the BF feedback simultaneously. The AP may transmit other BFRP Trigger frames to gather more feedbacks if necessary.\nCompressed BF feedback frame format: The HE MU Exclusive BF report is an extra field at the end of the frame for MU-MIMO, which thereby introduce extra CSI overhead;\nBF Feedback transmission: The BF feedback in SU-MIMO is transmitted over the UL OFDM while they are transmitted over the UL OFDMA in MU-MIMO."

+            "text": "CSI overhead in DL SU/MU-MIMO can be calculated based on the CSI frame format indicating each sub-field size, as shown in Fig. 2  ###reference_###. In particular, CSI overhead is dominated by HE compressed BF feedback that contains the HE compressed BF report (as well as the extra sub-field - HE MU Exclusive BF report in MU-MIMO). The compressed BF report contains the compressed CSI for each sub-carrier, i.e., the V-matrix or steering/precoding matrix555The Null-steering step based on zero-forcing (ZF) and minimum mean square error (MMSE) approaches [12  ###reference_b12###, 14  ###reference_b14###], used for precoding in DL MU-MIMO are not implemented in real AP products [10  ###reference_b10###, 7  ###reference_b7###] because those can be implemented only if the full CSI is obtained, whereas the feedback V-matrix provides only partial CSI. Besides, null-steering step incurs additional computational complexity and thus chipset cost for the AP. used for digital beamforming. V-matrix is obtained by a) applying the singular value decomposition (SVD) to the full CSI, and b) compressing it to specific Givens rotation angles to reduce the amount of required bits. The compressed size of the V-matrix depends on the total number of Givens rotation angles as well as the number of bits used to quantize each angle, as defined in IEEE 802.11ax specification. In general, the larger the V-matrix dimension, the more the number of angles. Meanwhile, the number of bits to quantize each angle is indicated by the sub-field of codebook information choice with 1 bit in the HE MIMO Control field. Thus both SU- and MU- have two codebook information choices [1  ###reference_b1###], however, MU-MIMO uses more bits than SU-MIMO to quantize a single angle by using the same codebook information. For instance, if codebook information bit is set to 0, the number of bits to quantize an angle in SU-MIMO is 4 or 2 while they are 7 or 5 in MU-MIMO [1  ###reference_b1###], implying that the compressed V-matrix in MU-MIMO has larger overhead compared to SU-MIMO. In addition, the HE compressed BF report size also scales with the number of spatial streams and the number of sub-carriers. The MU-Exclusive BF report in MU-MIMO contains the delta SNR per sub-carrier, which represents the difference from the average SNR. The MU-Exclusive BF report represents the spatial characteristics for each sub-carrier caused by the environment, the size of which scales with the number of subcarriers. Since the 802.11ax specification does not detail how this information is exploited in the design of the beamformer, its implementation is chip vendor dependent.\nAs discussed, channel sounding procedures introduce a significant cost in airtime because the sounding exchange must be completed before a beamformed data transmission can occur. Therefore, if the MU-MIMO BF gain is not sufficient to offset the airtime consumed by the sounding exchange, MU-MIMO throughput can be lower than the SU-MIMO in some operational scenarios.\n###figure_3### As Fig. 2  ###reference_### shows, a cycle of CSI overhead and HE data transmission is repeated in both DL SU and MU-MIMO. In each cycle, the transmitted data for each STA is filled in one Transmit opportunity (TXOP) comprised of multiple back-to-back PPDUs (e.g., 1500 bytes) in SIFS burst mode. Thus the data transmission duration is the maximum TXOP limit ( ms) compared to which the duration of access delay is negligible (typically less than a few hundred microseconds), as long as the number of STAs is not excessively large. If we assume STA\u2019s walking speed equal to 2 mph, the resulting channel coherence time 666Channel coherence time is defined as the time duration over which the channel is considered to be not varying. (15 ms) will be greater than any one cycle duration. Hence, it is reasonable to assume a block fading channel for each cycle, i.e., channel capacity is fixed in a cycle while varying across different cycles. We will use the effective channel capacity  to compare the SU and MU- performance as a function of CSI overhead - defined as the average channel capacity over both CSI overhead (zero channel capacity) duration and HE data transmission duration (non-zero channel capacity), given by\nwhere  denotes the total number of cycles,  denotes the Shannon channel capacity [14  ###reference_b14###] of the -th STA in the -th cycle, assumed to be constant due to the block fading channel.  is the ratio of CSI overhead airtime to the cycle duration for the -th cycle. Eq. (1  ###reference_###) applies to DL SU-MIMO when the size of  is 1. Note that  varies across  due to time-varying channels777For the pure analysis of CSI overhead in this section, the inter-user interference determined by spatial correlation is assumed to be zero. Thus  in terms of  changes only due to the channel gain variations rather than variations in inter-user interference. Then,  shown in Fig. 3  ###reference_### is the maximum effective channel capacity that DL MU-MIMO can reach., but  is independent of  in our model since we assume a specific setup (i.e., MIMO dimension, codebook information, and the number of selected STAs, TXOP duration).\nAssuming an 8 x 8 AP, 1 x 1 STA(s), and 20 MHz channel bandwidth as in Fig. 3  ###reference_###, the effective channel capacity does not grow linearly with the number of STAs. In particular, the effective channel capacity under codebook info 1 is greatly reduced when the number of STAs reaches 8. This can be explained by following reasons:\nCSI overhead proportion  shown in Fig. 3  ###reference_### grows exponentially with the number of STAs. This is because, on the one hand, an extra field - HE MU Exclusive BF report as a function of the number of sub-carriers and spatial streams - is included in HE compressed BF feedback, incurring extra CSI overhead; On the other hand, the bandwidth is shared using UL OFDMA leads to the lower UL data rate for HE compressed BF feedback transmission per STA; Thus, the DL MU-MIMO CSI overhead becomes significantly higher than SU-MIMO for a large number of STAs;\nAP transmit power is divided equally for each STA in DL MU-MIMO. As a result,  in Eq. (1  ###reference_###) will drop with increasing number of STAs due to the lower transmit power per STA.\nThe same phenomenon repeats for the 8 x 8 AP, 2 x 2 STA, and 20 MHz cases in Fig. 3  ###reference_###; the effective channel capacity is reduced when the number of STAs reaches 4. However, this does not indicate that AP shall not support more STAs due to the lower effective channel capacity. However, inspite of this result, AP vendors may choose to support greater number of STAs on simultaneous DL as that may be independently desirable[2  ###reference_b2###]. It is noteworthy that codebook info 1 (i.e., using more bits to quantize the V-matrix) always has lower effective channel capacity performance than codebook info 0 in Fig 3  ###reference_###. This is because we assume the perfect channel estimation which does not produce channel estimation error under both Codebook info 0 and 1. Thus codebook info 1 with larger CSI overhead always suffers more than codebook info 0."

Such models were introduced by Saleh and Valenzuela, and extended/elaborated upon by many other researchers [14  ###reference_b14###]. In particular, IEEE 802.11ax indoor channel model [11  ###reference_b11###] is a typical cluster-based channel model that we have adapted by incorporating a parameter for user separation, as shown in Fig. 4  ###reference_###. IEEE 802.11ax indoor channel model represents the propagation environment as a collection of scatterers grouped into clusters, where each cluster represents objects in the vicinity that act as a forward scattering source of rays that reach the receiver. Such clusters are typically represented via spatial-temporal models that capture the spatial characteristics of the environment, such as the transmit/receive antenna correlation and the distribution of objects, etc.\n###figure_4### A particular impact on our results arises from distinction between Line-of-sight (LoS) and Non-line-of-sight (NLoS) scenarios as defined by 11ax channel model specification, depending on the relationship between the breakpoint distance 888The breakpoint distance is defined as the distance that separates LoS and NLoS scenarios by characterizing different path loss exponents.  and the distance between AP and STA(s) [11  ###reference_b11###]:\nLoS scenario (Fig. 4  ###reference_###) occurs if the distance between AP and STAs is smaller than the breakpoint distance. The received signal at each STA include a LoS component and multiple multipath-induced NLoS components within a tapped delay-line model. This results in Rician fading multipath models where the first tap (corresponding to earliest arrival at each STA) is the LoS component. Therefore, the CSI obtained at each STA in such cases includes both LoS component and NLoS components with spatial characteristics [11  ###reference_b11###]; LoS CSI component depends on the transmit/receive steering vector parameterized by LoS angle of departure (AoD)/angle of arrival (AoA). Each NLoS CSI component depends on transmit/receive antenna correlation parameterized by NLoS mean AoD/AoA along with angular spread, and the spatial distribution of random scatterers within the cluster. The mathematical expression for LoS/NLoS CSI components can be found at [15  ###reference_b15###]. Since the first LoS tap signal is typically significantly stronger than NLoS signals, the LoS CSI component dominates the CSI obtained at each STA.\nNLoS scenario occurs if the distance between AP and STAs is greater than the breakpoint distance; then the LoS tap signal at each STA in Fig. 4  ###reference_### is blocked. Thus, the received signals at each STA are all NLoS (hence Rayleigh fading) and the first NLoS tap signal\u2019s power is close to that of the other NLoS taps.\n###figure_5###"

As a result, the corresponding V-matrices become highly correlated, incurring significantly higher inter-user interference than other user separation regions.\n###figure_6###"

Since the latter such as their distributions, shapes and properties of materials are random, each NLoS tap consists of superposition of multiple independent individual path components leading to the complex Gaussian assumption [11  ###reference_b11###]. As a result, the inter-user/inter-steam interference can vary significantly as a function of STA distance in such cases (and is insensitive to user angular separation).\nThe spatial correlation as a function of distance in NLoS is shown Fig. 5  ###reference_### for scenarios where the granularity of distance is 10 meters; the maximum distance for DL MU-MIMO operation with sufficiently high SNR at the STA is 60 meters. For each distance, 60 equally spaced user separations is used to calculate the proportion of scenarios in which MU channel capacity dominates SU. As shown, the proportion increases when distance increases, indicating that DL MU-MIMO benefits more than SU-MIMO at larger distance. In particular, MU becomes dominant over 50% scenarios for distances greater than 38 meters. The larger the distance is, the more the multiple scattering, reflection, and diffraction paths that decorrelate the signals received by different users. Hence, the inter-user interference is effectively reduced with the increasing distance."

For the same setup as Fig. 5  ###reference_### used to obtain the channel capacity is now modified to derive the effective channel capacity as in Fig. 3  ###reference_###. Meanwhile, We extend to a 4-user MU-MIMO operation, i,e, the user sub-set selection size is 4, indicating that upto 4 out of  STAs are selected if MU-MIMO is turned on. As the 4-user spatial correlation (where each is characterized by LoS/NLoS, user separation, and distance) results in a large set of scenario combinations, we thereby provide some typical scenarios due to the page limit. It should also be noted that real indoor channels might differ from the used channel model, that is, the exact spatial correlation threshold, such as  user separation and  meter distance in Section III  ###reference_###, used for turning on/off MU-MIMO might be different. However, real channels should have the same guideline trend as the used channel model under each operational scenario (without specifying specific thresholds) defined in Fig. 6  ###reference_###. All results were implemented in Matlab using indoor MIMO WLAN channel models created by Schumacher et al, [15  ###reference_b15###].\nAs the main features regarding CSI overhead are codebook information for BF compression (i.e., codebook info 0 and 1) and STA MIMO dimensions (i.e., 1 x 1 and 2 x 2 STA), there are a total of 4 operational scenarios regarding CSI overhead. Meanwhile, we provide 5 typical operational scenarios (i.e., 2 LoS and 3 NLoS scenarios 101010For the operational scenario of two at small distances and two at large distances, AP is assumed to serve one of the STAs at small distances if MU-MIMO is turned off.) regarding spatial correlation. As a result, we provide guidelines for 20 scenarios unifying both CSI overhead and spatial correlation, as shown in Fig. 6  ###reference_###. Our conclusion for the 2-user case is that among these 20 scenarios, DL MU-MIMO can be turned on in 9 (45%). According to the guideline table, DL MU-MIMO can be turned on in the following scenarios:\n1 x 1 STAs with sufficient user separation in LoS;\n2 x 2 STAs with codebook info 0 and sufficient user separation in LoS;\n1 x 1 STAs in NLoS;\n2 x 2 STAs with codebook info 0 and large distances in NLoS.\nOtherwise, DL MU-MIMO is suggested to be turned off, i.e., switch to DL SU-MIMO. Note that the condition for turning on DL MU-MIMO is more stringent for the 2 x 2 STA case, compared to the 1 x 1 STA case. This is because each spatial stream in the 2 x 2 STA case suffers more from interfering streams (self-interference from another stream for the same STA and/or streams from another STA) than the 1 x 1 STA case (only one interfering stream from another STA). Thus compared to the 1 x 1 STA case, MU-MIMO effective channel capacity is less likely to exceed SU-MIMO in the 2 x 2 STA case."

In practical use cases, new generation algorithms are continually emerging, and these algorithms are not encountered during the development of detection methods. This calls for the generalization ability of the method. Additionally, to ensure the credibility of detection methods, it is beneficial for the model to interpret which cues from the video indicate it is fake. Motivated by these considerations, we then propose a multi-stream fusion approach with one-class learning as a representation-level regularization technique. We study the generalization problem of audio-visual deepfake detection by creating a new benchmark by extending and re-splitting the existing FakeAVCeleb dataset. The benchmark contains four categories of fake videos (Real Audio-Fake Visual, Fake Audio-Fake Visual, Fake Audio-Real Visual, and Unsynchronized videos).\nThe experimental results demonstrate that our approach surpasses the previous models by a large margin.\nFurthermore, our proposed framework offers interpretability, indicating which modality the model identifies as more likely to be fake.

+            "text": "Recent advancements in deep learning, including Stable Diffusion [1  ###reference_b1###] and Sora, have enabled the generation of highly realistic images and audio, collectively referred to as deepfakes. The availability of numerous easy-to-use tools for generating deepfake videos significantly increases the chance of misuse of those media, as even non-experts can now create convincing fake content with minimal effort. This emphasizes the urgency for developing robust detection mechanisms to mitigate the risks associated with deepfakes.\nVideos, particularly those featuring a person speaking, have become a significant medium for disseminating deepfake information. Detecting these deepfakes requires joint consideration of both audio and visual modalities. The speech could be generated from text-to-speech [2  ###reference_b2###] and voice conversion algorithms [3  ###reference_b3###, 4  ###reference_b4###], and the videos are either face-swap [5  ###reference_b5###] from an original video or further rendered from speech and a still image [6  ###reference_b6###].\nAdditionally, while synchronization might be disrupted by modifying audio or visual modality, the generated modality can still be seamlessly synchronized with its corresponding counter modalities using lip-sync technologies [7  ###reference_b7###, 8  ###reference_b8###]. This ensures the creation of highly realistic fake videos.\nThis underscores the need for researchers to develop audio-visual deepfake detection mechanisms that surpass the capabilities of unimodal deepfake detection approaches.\nRecent research focuses mainly on the fusion of features of both modalities to improve the detection performance on audio-visual deepfake datasets [9  ###reference_b9###, 10  ###reference_b10###, 11  ###reference_b11###]. By leveraging the complementary nature of audio and visual data, these approaches effectively improve their accuracy in identifying manipulated content.\nHowever, two issues are not well explored: First, the existing deep learning models may overfit to the specific fake generation methods present in the training data, leading to poor generalization when confronted with unseen deepfake generation algorithms in real-world scenarios. This could be attributed to the existing dataset design [12  ###reference_b12###, 13  ###reference_b13###] that does not benchmark the generalization ability for the models. This overfitting issue would limit the practical applicability of these models, as they fail to adapt to the rapidly evolving landscape of deepfake techniques. Second, existing approaches lack the ability to identify the modality source of a detected deepfake. This limitation arises because these systems are trained and tested using only the final audio-visual labels, without incorporating meta-information about the individual modalities.\nA model able to tell which modality is fake would enhance the interpretability and credibility in practice.\nIn this work, we propose a novel framework Multi-Stream Fusion Approach with One-Class Learning (MSOC) to tackle audio-visual deepfake detection, enhancing the generalization ability and interoperability. We extend the one-class learning approach, previously proposed in uni-modal contexts, to the audio-visual setting. We validate the generalization ability by resplitting the FakeAVCeleb [12  ###reference_b12###] dataset and separating the unseen algorithms into the test set. We curated four test sets (RAFV, FAFV, FARV, Unsynced)\nthat cover all kinds of fake categories.\nWe will make the dataset splits and model implementation publicly available upon the publication of this paper.\nOur contributions are summarized as:\nExtending one class learning from uni-modal to audio-visual deepfake detection;\nA multi-stream framework with audio-visual (AV), audio (A), and visual (V) branches;\nA curated dataset for evaluating performance on unseen generation methods based on FakeAVCeleb."

However, uni-modal models are inherently limited to a single modality and cannot completely detect emerging deepfake videos that both audio and visual can be generated. To address this problem, recent research has started to focus on developing audio-visual deepfake detection models.\nInitially, many studies have focused on explicit synchronization issues between audio and visual modalities in deepfakes.\nShahzad et al. [17  ###reference_b17###] argue that altering either audio or visual can desynchronize speech and lip movements in videos. In addition, researchers have investigated the representation-level inconsistency due to single-modality manipulations. The modality dissonance score was introduced in [18  ###reference_b18###] to quantify the dissimilarities between the modality features. However, these methods may struggle to detect deepfakes where both audio and video are both generated in a more consistent way, such as text-to-speech followed by lip synch [12  ###reference_b12###].\nSeveral studies also develop audio-visual representations by integrating features from uni-modal feature extractors and mapping them to audio-visual targets [11  ###reference_b11###, 19  ###reference_b19###]. However,\nrecent studies [10  ###reference_b10###, 9  ###reference_b9###] claim that using only multimodal labels can misinform the data from the unimodal feature extractor during joint training.\nEnsemble models have also been studied [20  ###reference_b20###, 21  ###reference_b21###, 22  ###reference_b22###]. They combine models for audio, visual, and audio-visual data and leverage the strengths of each modality-specific model to enhance overall detection accuracy."

Additionally, there is a greater variety of visual deepfake generation methods compared to audio modalities. In terms of attribute labeling, the FakeAVCeleb dataset attempts to present different categories of fakes, but the FARV category includes not only fake audio but also unsynchronized audio. This makes it difficult for methods to learn fake audio cues, since they are confounded with synchronization cues. Our study proposes extended datasets and new partitions to address these issues."

However, since deepfake generation techniques are rapidly developing, deepfake attacks in practice are often unseen during training of deepfake detection models, and these binary classification models show significantly degraded performance on unseen attacks [23  ###reference_b23###]. To address this issue, Zhang et al. [14  ###reference_b14###] proposed the idea of one-class learning for speech deepfake detection. The idea was to use a so-called One-Class Softmax (OC-Softmax) loss to guide the neural network to learn an embedding space where bonafide speech utterances are clustered together while fake speech utterances are pushed away from this cluster during training:\nwhere  (center) is the normalized weight vector for the target class;  is the normalized embedding vector of the -th sample;  and  are margins for the real and fake classes, respectively.  is the number of samples in a mini-batch, and  is a scale factor. For each utterance, the cosine similarity between the feature embedding and the weight vector, , is called the OC score, a value between -1 and 1.\nSince then, many works on speech anti-spoofing have adopted the idea of one-class learning [24  ###reference_b24###, 15  ###reference_b15###, 25  ###reference_b25###]. The results show that models trained with one-class learning can effectively identify fakes as deviations from the learned bonafide embedding cluster for speech.\nDespite these advantages, the generalizability of one-class learning for audio-visual deepfake detection has not been thoroughly studied due to dataset limitations. This study addresses this gap by re-splitting the FakeAVCeleb dataset [12  ###reference_b12###] and analyzing the effectiveness of one-class learning in audio-visual deepfake detection."

The comparison of models\u2019 performance on test datasets is presented in Table I  ###reference_###.\nWe can observe that state-of-the-art models perform poorly on unseen generation methods, which shows their lack of generalization ability. Our proposed model MSOC outperforms other models on FAFV, RAFV, and FARV test sets.\nThis indicates that multi-stream architecture with OC-Softmax successfully separated bonafide and generated data by compacting embedding of bonafide data, which resulted in better generalizability than other models in all combinations of fake modality.\nAs shown in the last column of Table I  ###reference_###, all models perform poorly (close to random guessing) when identifying unsynchronized videos, which should be clearly recognized as fake. This is the first time these models have been tested on this unsynchronization benchmark, and our model exhibits general characteristics similar to existing fusion-based methods. The results suggest that training the audio and visual encoders with real/fake labels alone is insufficient to capture synchronization. We believe that incorporating an explicit module to learn audio-visual synchronization [31  ###reference_b31###, 32  ###reference_b32###] could address this issue, but we leave this for future work.\nAdditionally, we compare the MSOC framework with AVOC models. Table II  ###reference_### shows that MSOC models generally perform better than AVOC.

The MSOC model has three branches, providing enhanced performance and interpretability.\nFig. 2  ###reference_### visualizes the distribution of scores for each branch on four categories of fake videos.\nThe audio and visual score, OC scores , are calculated based on the cosine similarity between the bonafide embedding and the feature embedding of the respective modality. The audio-visual score represents the softmax probability that a video is real , calculated with audio-visual characteristics and audio-visual labels.\nThe figure shows that the audio-visual branch performs well when both modalities are fake (FAFV), predicting a probability close to 0 for all fake samples. However, the audio-visual branch exhibits greater confusion when only one modality is fake. The audio branch excels at distinguishing audio fake(Fig. 2(b)  ###reference_sf2###) and real samples(Fig. 2(a)  ###reference_sf1###). Also, the visual branch exhibits great performance in identifying real samples (Fig. 2(b)  ###reference_sf2###), although it fails to detect some fake samples (Fig. 2(a)  ###reference_sf1###). This highlights the benefit of using both the audio and visual branches.\nAdditionally, the audio and visual branches offer better interpretability of the model\u2019s decisions. With AVOC model, it is impossible to determine which modality the model perceives as fake. However, with MSOC, by analyzing the individual scores from branches, one can identify which modality contributes to the final result, providing insights into whether the audio or visual aspect is being manipulated. Therefore, leveraging all branches improves performance and enhances the transparency and reliability of the model\u2019s predictions."

Thus,\nthis section examines the impact of visual feature extractors in one-class learning. Although OC-Softmax effectively compacts genuine representations and distributes fake representations, its performance is limited if the visual feature extractor fails to capture the general features of fake visual artifacts. This limitation arises because OC-Softmax compacts real representations based on observed attacks and real data, potentially including unseen attack representations within the realm of genuine representations. Therefore, extracting more general features of fake videos, such as Spatial-Temporal Inconsistency, could be beneficial.\nFig. 4  ###reference_### compares the visual scores from both visual feature extractors. We can observe that the ResNet-based visual feature extractor lacks the ability to detect unseen fake methods effectively compared to the SCNet-STIL-based visual feature extractor. This explains why models with the STIL feature extractor significantly outperform models with a ResNet feature extractor on the RAFV test set.\n###figure_7### ###figure_8###"

+    "abstract": "Reasoning about time is essential for Large Language Models (LLMs) to understand the world. Previous works focus on solving specific tasks, primarily on time-sensitive question answering.\nWhile these methods have proven effective, they cannot generalize to a wider spectrum of temporal reasoning tasks.\nTherefore, we propose a crucial question: Can we build a universal framework to handle a variety of temporal reasoning tasks?\nTo that end, we systematically study 38 temporal reasoning tasks.\nBased on the observation that 19 tasks are directly related to mathematics, we first leverage the available mathematical dataset to set a solid foundation for temporal reasoning.\nHowever, the in-depth study indicates that focusing solely on mathematical enhancement falls short of addressing pure temporal reasoning tasks. To mitigate this limitation, we propose a simple but effective self-critic temporal optimization method to enhance the model\u2019s temporal reasoning capabilities without sacrificing general task abilities.\nFinally, we develop Timo, a model designed to excel in temporal reasoning at the 7B and 13B scales. Notably, Timo outperforms the counterpart LLMs by 10.0 and 7.6 in average accuracy scores and achieves the new state-of-the-art (SOTA) performance of comparable size. Extensive experiments further validate our framework\u2019s effectiveness and its generalization across diverse temporal tasks. The code is\navailable at https://github.com/zhaochen0110/Timo.",

+            "text": "Large Language Models (LLMs) have achieved remarkable success in various reasoning tasks (Zhou et al., 2022  ###reference_b67###; Zhao et al., 2023  ###reference_b64###; Chang et al., 2023  ###reference_b3###), such as\nmathematical, commonsense, and symbolic reasoning.\nDespite these advances, LLMs face significant challenges in temporal reasoning (Chen et al., 2021  ###reference_b4###; Tan et al., 2023a  ###reference_b44###), which is crucial in human perception.\nCompared to other reasoning tasks that focus solely on one specific reasoning ability, temporal reasoning is an integrated task that requires arithmetic (Zhu et al., 2023a  ###reference_b68###), logic (Mishra et al., 2022a  ###reference_b26###) and world knowledge (Wei et al., 2022  ###reference_b52###).\nPrior efforts to improve the temporal reasoning capacity of LLMs focus mainly on time-sensitive question-answering (Chen et al., 2021  ###reference_b4###), and utilize methods such as step-by-step reasoning (Zhu et al., 2023b  ###reference_b69###; Li et al., 2023  ###reference_b20###) and ruled-based supervised fine-tuning (SFT) (Tan et al., 2023a  ###reference_b44###; Yuan et al., 2023b  ###reference_b57###).\nMore recent studies expand the scope of temporal tasks to include basic temporal concepts understanding (e.g., duration), intricate temporal interpretations (e.g., relation) and computations (e.g., arithmetic) (Wang & Zhao, 2023  ###reference_b51###).\nDue to their task-specific nature, the aforementioned methods exhibit limited generalization across the wider spectrum of temporal tasks.\n###figure_1### ###figure_2### To address these limitations, we explore a crucial question: Can we build a universal framework to handle a variety of temporal reasoning tasks?\nTo tackle this question, we face the following challenges:\n(1) integrating different temporal reasoning tasks into a unified framework;\n(2) generating and selecting the high-quality training dataset automatically;\n(3) improving the comprehensive temporal reasoning abilities while maintaining its general performance.\nIn response to these challenges, we first systematically study 38 subtasks within the temporal reasoning benchmark proposed by Wang & Zhao (2023  ###reference_b51###).\nAs shown in Figure 2  ###reference_###, our analysis reveals that 19 tasks are directly related to mathematical reasoning (i.e., mathematical time tasks).\nFor example, when \u201cidentifies the next leap year following 2024\u201d, mathematical skills are required to calculate the results.\nThe rest are categorized as pure temporal reasoning tasks, focusing solely on temporal reasoning without using mathematical abilities.\nMeanwhile, mathematical reasoning stands out with its diverse and rich instruction tuning datasets compared to temporal reasoning (Cobbe et al., 2021  ###reference_b7###; Mishra et al., 2022b  ###reference_b27###; Yue et al., 2023  ###reference_b59###).\nTherefore, it is intuitive to build a generalist temporal reasoning framework based on math-enhanced LLMs, setting a solid foundation for temporal reasoning skills.\nHowever, our in-depth study indicates that focusing solely on mathematical enhancement through supervised fine-tuning falls short of addressing pure-time tasks.\nTo bridge this gap, we further introduce a simple but effective method to obtain comprehensive temporal reasoning abilities.\nSpecifically, we propose a self-critic method to generate and select the high-quality temporal preference pairs, which are then utilized for enhancing model temporal capabilities through\npreference optimization.\nFinally, we propose a unified temporal reasoning framework, namely Timo. With this framework, our model achieves superior performance among 38 temporal tasks, as depicted in Figure 2  ###reference_###.\nIn our experiments, we train LLaMA2 models at both 7B and 13B scales with our framework, which results in Timo-7B and Timo-13B. These two models demonstrate a substantial improvement of 10.0 and 7.6 in average accuracy\nscores over the base models, respectively.\nOur comprehensive analysis indicates that our framework successfully integrates substantial mathematical knowledge along with temporal information.\nExtensive experiments further verify the effectiveness of our method in preserving general task capabilities and maintaining robustness under different scenarios.\nTo sum up, our contributions are shown below:\n(1) we systematically study diverse temporal reasoning tasks and discover the inner correlation between time and mathematics, where temporal reasoning could benefit from math instructions;\n(2) we make the first attempt to build a unified framework to address 38 temporal tasks. Specifically, upon mastering mathematical reasoning capabilities, we propose a simple but effective self-critic temporal optimization method to strengthen the temporal reasoning capabilities comprehensively;\n(3) the proposed framework outperforms 10.0 and 7.6 scores over the baselines, establishing as the new SOTA model of comparable sizes. Besides, our models consistently enhance the temporal reasoning capabilities without sacrificing general task performance."

In the Ambiguity Resolution task, mathematics provides a standardized method of time representation, such as the 24-hour format and date calculation formulas, enabling different temporal expressions to be accurately understood and converted.\nBased on these observations, we categorize temporal tasks into two categories. The specific subtasks under each category are shown in Figure 2  ###reference_###. Below is our classification:\nMathematical Time Tasks (Math-time tasks): These are temporal reasoning tasks that necessitate mathematical skills, such as calculating time frequencies, converting time shifts, comparing time sequences and so on. This category encompasses a total of 19 subtasks.\nPure Time Tasks (Pure-time tasks): These tasks require only temporal reasoning abilities for resolution and include reasoning about temporal commonsense, applications in real-world scenarios, temporal natural language inference (NLI) and so on.

The baselines are selected based on the following dimensions:\nLLMs for Temporal Reasoning: TimeLLaMA (Yuan et al., 2023b  ###reference_b57###) is currently the only open-source model that is specifically designed for temporal reasoning. It is developed to make temporal predictions and generate time-related explanations.\nLLMs for Mathematical Reasoning: Timo is trained through temporal optimization based on mathematical models. Here, we compare the following mainstream mathematical models:\n(1) MAmmoTH (Yue et al., 2023  ###reference_b59###) is designed for general mathematics problem-solving and is trained on the MathInstruct dataset.\n(2) WizardMath (Luo et al., 2023a  ###reference_b24###) utilizes the proposed Reinforcement Learning from Evol-Instruct Feedback (RLEIF) (Xu et al., 2023  ###reference_b55###) to enhance its mathematical reasoning capabilities.\n(3) ToRA (Gou et al., 2024  ###reference_b13###), a series of Tool-integrated Reasoning LLM Agents, is designed to solve challenging mathematical reasoning problems.\nLLMs for Code Generation: Previous work indicates that the usage of code enhances the model\u2019s ability to solve reasoning tasks (Gao et al., 2023  ###reference_b12###). We select the following popular code models as our baselines:\n(1) CodeLLaMA (Roziere et al., 2023  ###reference_b35###), a family of LLMs for code generation and programming-related tasks.\n(2) WizardCoder (Luo et al., 2023b  ###reference_b25###) is similar to WizardMath and adapts the RLEIF method within the domain of coding.\nTable 4.1  ###reference_.SSS0.Px3### presents the results of Timo across 38 temporal tasks. From the results, we observe:\n(1) Timo surpasses counterpart LLMs in average accuracy of 10.0 and 7.6 scores, and outperforms other competitive math-solving and code-solving models with a clear margin, achieving the SOTA results on average.\nWe also discover Timo-7B consistently outperforms all 13B models in average performance, achieving a maximum performance gain of 7.1.\n(2) Mathematical models do not show significant advantages in solving math-related tasks. This phenomenon is also observed in LLMs enhanced for coding abilities and temporal prediction capabilities. It indicates that excessive training on specific abilities leads the model to overfit in task-centric enhancements, diminishing its performance in other areas (Jha et al., 2023  ###reference_b17###).\n(3) It is worth noting that Timo underperforms MAmmoTH in the Arithmetic task (i.e., scoring 66.3 vs 67.0) when evaluated under the 13B model size parameter.\nThe superior performance of MAmmoTH can be attributed to its advanced general math-solving abilities, which facilitate more accurate computations in time-related scenarios.\nHowever, other mathematical models like ToRA and WizardMath do not achieve the same effectiveness in handling the Arithmetic task.\nA detailed case study for illustration is in Appendix B  ###reference_###.\nWe compare the model\u2019s performance on both math-time tasks and pure-time tasks.\nThe results are shown in Figure 6  ###reference_###.\nCompared to the foundational model LLaMA, MathLLaMA demonstrates superior performance in math-related tasks and surpasses the LLaMA in the majority of pure-time tasks, achieving higher scores in 6 out of 9 tasks. This improvement is attributed to the advanced logical and reasoning skills developed through mathematical instruction tuning (Mishra et al., 2022a  ###reference_b26###).\nWhen compared to Timo and MathLLaMA, our framework demonstrates strong generalization capabilities, achieving significant improvement in pure-time tasks, with only minimal performance degradation in the arithmetic task.\nAdditionally, it is worth noting that Timo outperforms MathLLaMA in various math-time tasks (i.e., Ambiguity Resolution, Duration and Frequency). This improvement is attributed to our framework\u2019s ability to learn generalized temporal features.\nTo understand the learning process and the differences between the different stages of our framework, we follow the methodology proposed by Lin et al. (2024  ###reference_b21###) to analyze through the lens of token distribution shift.\nWe analyze three pairs of models at the 7B scale: LLaMA vs MathLLaMA, MathLLaMA vs Timo, and LLaMA vs Timo.\nThe results are shown in Figure 7  ###reference_###.\nNotably, we observe the largest token distribution shift when transitioning from LLaMA to Timo.\nFurthermore, we investigate the top 200 most frequently shifted tokens, labeling math-related tokens in red and time-related tokens in green.\nThe transition from LLaMA to MathLLaMA primarily features changes in math-related tokens. Conversely, the switch from MathLLaMA to Timo is characterized by the presence of time-related tokens. When compared to LLaMA, Timo exhibits shifts in both math-related and time-related tokens, demonstrating a profound capacity to integrate substantial mathematical knowledge along with the temporal information.\nAs shown in Table 2  ###reference_###, we present a case analysis to provide a clear and intuitive demonstration of Timo\u2019s superior performance.\nIn math-time tasks, both MathLLaMA and Timo effectively integrate temporal knowledge with computational capabilities to give the correct CoT and answer.\nHowever, LLaMA produces an incorrect result due to the error in time calculation, which indicates the importance of mathematical skills in solving math-time tasks.\nIn our provided case of the pure-time tasks, both MathLLaMA and LLaMA fail to grasp the sequence of events, i.e., the timing of Amy\u2019s laundry activities. On the other hand, Timo demonstrates a strong understanding and application of temporal reasoning, accurately tracking the sequence and timing of Amy\u2019s activities and giving the correct answer.\nOverall, these cases vividly demonstrate Timo\u2019s comprehensive capabilities in temporal reasoning across different temporal task types.\n###figure_7### We compare Timo-13B with the current most powerful LLMs, i.e., GPT-3.5 and GPT-4.\nSpecifically, we use the gpt-3.5-turbo-1106 and gpt-4-1106-preview and set the temperature to 0 for consistent evaluation.\nThe results are shown in Figure 6  ###reference_###.\nDespite its relatively small size of 13B parameters, Timo demonstrates impressive performance on pure-time tasks, outperforming GPT-3.5 in 7 out of 9 tasks and surpassing GPT-4 in 5 out of 9 tasks. Notably, Timo exceeds GPT-4 by a significant margin of 38 accuracy scores in the Relation task.\nAlthough there has been a significant improvement in pure-time tasks, the performance on math-time tasks suggests that there is still room for further enhancement.\nThis is attributed to the foundational model\u2019s weaker mathematical reasoning capabilities. We leave it as future work to further improve the model\u2019s temporal reasoning abilities by better integrating mathematics capabilities.\nIn our framework, we design a series of criteria to assess the standard of responses and obtain high-quality temporal preference pairs.\nTo verify the effectiveness of our criteria, we compare our prompting approach with the widely adopted self-rewarding strategy (Yuan et al., 2024  ###reference_b58###) and the random selection strategy.\nAs shown in Table 3  ###reference_###, our strategy outperforms others in both math-time and pure-time tasks, highlighting its superiority in evaluating the quality of generated responses across different types of temporal challenges.\nWith Timo being derived from a mathematical model trained with 100k math instructions, we validate the robustness and adaptability of our framework across different mathematical models, which is achieved by implementing self-critic temporal task optimization in models supervised fine-tuned with different volumes of instruction dataset (i.e., 50k, 100k, 150k, 180k).\nThe results are shown in Figure 9  ###reference_###.\nThe experiments show that the trained models consistently outperform in handling time-related tasks compared to their corresponding mathematical models, highlighting our method\u2019s capability to enhance temporal reasoning across different mathematical training backgrounds.\nTo verify the model\u2019s ability to retain its original capabilities, we utilize the lm-evaluation-harness (Gao et al., 2021  ###reference_b11###) to evaluate its performance on six typical downstream tasks: 5-shot MMLU (Hendrycks et al., 2020  ###reference_b14###), 25-shot ARC Challenge (Clark et al., 2018  ###reference_b6###), 5-shot GSM8K (Cobbe et al., 2021  ###reference_b7###), 10-shot HellaSwag (Zellers et al., 2019  ###reference_b60###), 5-shot Winogrande (Sakaguchi et al., 2021  ###reference_b37###) and 0-shot TruthfulQA (Lin et al., 2022  ###reference_b22###).\nIn addition to comparing with LLaMA and MathLLaMA, we introduce Timo-SFT, which mirrors our framework in all aspects except for its training methodology.\nSpecifically, Timo-SFT is supervised fine-tuned with the chosen responses in the selected preference pairs.\nThe results are shown in Figure 9  ###reference_###.\nWe surprisingly discover that Timo outperforms other baselines in the reasoning and general knowledge ability tasks.\nError analysis shows that our model aligns with the base model for 97% of the correct responses. This consistency indicates that our Timo effectively preserves general task knowledge, demonstrating remarkable generalization capabilities.\n###figure_8### ###figure_9### Time is a crucial dimension in our physical world (Lazaridou et al., 2021  ###reference_b19###; Su et al., 2022  ###reference_b40###; 2023  ###reference_b41###; Zhao et al., 2024  ###reference_b62###). Despite the advanced capabilities of LLMs in various tasks, their reasoning abilities are still underdeveloped (Su et al., 2024  ###reference_b42###; Qiao et al., 2023  ###reference_b30###; Huang & Chang, 2023  ###reference_b15###; Sun et al.,  ###reference_b43###; Chu et al., 2023  ###reference_b5###).\nTemporal reasoning, which is fundamental for humans to understand the world, is an important task in reasoning and has gained substantial research focus (Pustejovsky, 2003  ###reference_b29###; UzZaman et al., 2012  ###reference_b49###; Huang et al., 2024  ###reference_b16###).\nHowever, existing works often specialize in limited aspects of temporal reasoning, such as frequency (Zhou et al., 2019  ###reference_b66###), duration (Zhang & Choi, 2021  ###reference_b61###), or event-time relations (Chen et al., 2021  ###reference_b4###; Tan et al., 2023a  ###reference_b44###).\nIn our work, we address a comprehensive scope of temporal reasoning, including various levels and dimensions of understanding about time (Wang & Zhao, 2023  ###reference_b51###).\nDiffering from prior approaches that rely on external knowledge (Yuan et al., 2023a  ###reference_b56###; Tan et al., 2023b  ###reference_b45###; Xiong et al., 2024  ###reference_b54###) or impose temporal constraints (Li et al., 2023  ###reference_b20###; Zhu et al., 2023b  ###reference_b69###) within a narrow sub-scope of tasks, we propose a unified framework designed to generalize across different temporal reasoning scenarios.\nPreference optimization approaches typically involve training a fixed reward model based on preference data, and then utilizing the reward\nmodel to train via reinforcement learning (RL) (Schulman et al., 2017  ###reference_b38###; Ziegler et al., 2019  ###reference_b70###; Stiennon et al., 2020  ###reference_b39###; Bai et al., 2022  ###reference_b1###).\nTo simplify this process, Direct Preference Optimization (DPO) (Rafailov et al., 2023  ###reference_b33###) is introduced to avoid training the reward model entirely, and instead directly train the LLM using preference pairs.\nBuilding on this approach, recent works explore automatic optimization and self-correction in LLMs (Pan et al., 2023  ###reference_b28###; Ji et al., 2024  ###reference_b18###).\nThis involves two key steps: instructing LLMs to self-generate their training dataset (Wang et al., 2023  ###reference_b50###; Taori et al., 2023  ###reference_b46###; Tunstall et al., 2023  ###reference_b48###; Liu et al.,  ###reference_b23###) and serving LLMs as reward models (Fernandes et al., 2023  ###reference_b10###; Saha et al., 2023  ###reference_b36###; Dubois et al., 2024  ###reference_b9###) to select high-quality data.\nThe self-generated data optimization enables models to iteratively improve their performance through a self-rewarding mechanism (Yuan et al., 2024  ###reference_b58###).\nInspired by the above works, we introduce a self-critic temporal optimization method that leverages the inherent capabilities of the model itself to achieve significant improvements in all temporal tasks."

We select the following popular code models as our baselines:\n(1) CodeLLaMA (Roziere et al., 2023  ###reference_b35###  ###reference_b35###), a family of LLMs for code generation and programming-related tasks.\n(2) WizardCoder (Luo et al., 2023b  ###reference_b25###  ###reference_b25###) is similar to WizardMath and adapts the RLEIF method within the domain of coding.\nTable 4.1  ###reference_.SSS0.Px3###  ###reference_.SSS0.Px3### presents the results of Timo across 38 temporal tasks. From the results, we observe:\n(1) Timo surpasses counterpart LLMs in average accuracy of 10.0 and 7.6 scores, and outperforms other competitive math-solving and code-solving models with a clear margin, achieving the SOTA results on average.\nWe also discover Timo-7B consistently outperforms all 13B models in average performance, achieving a maximum performance gain of 7.1.\n(2) Mathematical models do not show significant advantages in solving math-related tasks. This phenomenon is also observed in LLMs enhanced for coding abilities and temporal prediction capabilities. It indicates that excessive training on specific abilities leads the model to overfit in task-centric enhancements, diminishing its performance in other areas (Jha et al., 2023  ###reference_b17###  ###reference_b17###).\n(3) It is worth noting that Timo underperforms MAmmoTH in the Arithmetic task (i.e., scoring 66.3 vs 67.0) when evaluated under the 13B model size parameter.\nThe superior performance of MAmmoTH can be attributed to its advanced general math-solving abilities, which facilitate more accurate computations in time-related scenarios.\nHowever, other mathematical models like ToRA and WizardMath do not achieve the same effectiveness in handling the Arithmetic task.\nA detailed case study for illustration is in Appendix B  ###reference_###  ###reference_###.\nWe compare the model\u2019s performance on both math-time tasks and pure-time tasks.\nThe results are shown in Figure 6  ###reference_###  ###reference_###.\nCompared to the foundational model LLaMA, MathLLaMA demonstrates superior performance in math-related tasks and surpasses the LLaMA in the majority of pure-time tasks, achieving higher scores in 6 out of 9 tasks. This improvement is attributed to the advanced logical and reasoning skills developed through mathematical instruction tuning (Mishra et al., 2022a  ###reference_b26###  ###reference_b26###).\nWhen compared to Timo and MathLLaMA, our framework demonstrates strong generalization capabilities, achieving significant improvement in pure-time tasks, with only minimal performance degradation in the arithmetic task.\nAdditionally, it is worth noting that Timo outperforms MathLLaMA in various math-time tasks (i.e., Ambiguity Resolution, Duration and Frequency). This improvement is attributed to our framework\u2019s ability to learn generalized temporal features.\nTo understand the learning process and the differences between the different stages of our framework, we follow the methodology proposed by Lin et al. (2024  ###reference_b21###  ###reference_b21###) to analyze through the lens of token distribution shift.\nWe analyze three pairs of models at the 7B scale: LLaMA vs MathLLaMA, MathLLaMA vs Timo, and LLaMA vs Timo.\nThe results are shown in Figure 7  ###reference_###  ###reference_###.\nNotably, we observe the largest token distribution shift when transitioning from LLaMA to Timo.\nFurthermore, we investigate the top 200 most frequently shifted tokens, labeling math-related tokens in red and time-related tokens in green.\nThe transition from LLaMA to MathLLaMA primarily features changes in math-related tokens. Conversely, the switch from MathLLaMA to Timo is characterized by the presence of time-related tokens. When compared to LLaMA, Timo exhibits shifts in both math-related and time-related tokens, demonstrating a profound capacity to integrate substantial mathematical knowledge along with the temporal information.\nAs shown in Table 2  ###reference_###  ###reference_###, we present a case analysis to provide a clear and intuitive demonstration of Timo\u2019s superior performance.\nIn math-time tasks, both MathLLaMA and Timo effectively integrate temporal knowledge with computational capabilities to give the correct CoT and answer.\nHowever, LLaMA produces an incorrect result due to the error in time calculation, which indicates the importance of mathematical skills in solving math-time tasks.\nIn our provided case of the pure-time tasks, both MathLLaMA and LLaMA fail to grasp the sequence of events, i.e., the timing of Amy\u2019s laundry activities. On the other hand, Timo demonstrates a strong understanding and application of temporal reasoning, accurately tracking the sequence and timing of Amy\u2019s activities and giving the correct answer.\nOverall, these cases vividly demonstrate Timo\u2019s comprehensive capabilities in temporal reasoning across different temporal task types.\n###figure_10### We compare Timo-13B with the current most powerful LLMs, i.e., GPT-3.5 and GPT-4.\nSpecifically, we use the gpt-3.5-turbo-1106 and gpt-4-1106-preview and set the temperature to 0 for consistent evaluation.\nThe results are shown in Figure 6  ###reference_###  ###reference_###.\nDespite its relatively small size of 13B parameters, Timo demonstrates impressive performance on pure-time tasks, outperforming GPT-3.5 in 7 out of 9 tasks and surpassing GPT-4 in 5 out of 9 tasks. Notably, Timo exceeds GPT-4 by a significant margin of 38 accuracy scores in the Relation task.\nAlthough there has been a significant improvement in pure-time tasks, the performance on math-time tasks suggests that there is still room for further enhancement.\nThis is attributed to the foundational model\u2019s weaker mathematical reasoning capabilities. We leave it as future work to further improve the model\u2019s temporal reasoning abilities by better integrating mathematics capabilities.\nIn our framework, we design a series of criteria to assess the standard of responses and obtain high-quality temporal preference pairs.\nTo verify the effectiveness of our criteria, we compare our prompting approach with the widely adopted self-rewarding strategy (Yuan et al., 2024  ###reference_b58###  ###reference_b58###) and the random selection strategy.\nAs shown in Table 3  ###reference_###  ###reference_###, our strategy outperforms others in both math-time and pure-time tasks, highlighting its superiority in evaluating the quality of generated responses across different types of temporal challenges.\nWith Timo being derived from a mathematical model trained with 100k math instructions, we validate the robustness and adaptability of our framework across different mathematical models, which is achieved by implementing self-critic temporal task optimization in models supervised fine-tuned with different volumes of instruction dataset (i.e., 50k, 100k, 150k, 180k).\nThe results are shown in Figure 9  ###reference_###  ###reference_###.\nThe experiments show that the trained models consistently outperform in handling time-related tasks compared to their corresponding mathematical models, highlighting our method\u2019s capability to enhance temporal reasoning across different mathematical training backgrounds.\nTo verify the model\u2019s ability to retain its original capabilities, we utilize the lm-evaluation-harness (Gao et al., 2021  ###reference_b11###  ###reference_b11###) to evaluate its performance on six typical downstream tasks: 5-shot MMLU (Hendrycks et al., 2020  ###reference_b14###  ###reference_b14###), 25-shot ARC Challenge (Clark et al., 2018  ###reference_b6###  ###reference_b6###), 5-shot GSM8K (Cobbe et al., 2021  ###reference_b7###  ###reference_b7###), 10-shot HellaSwag (Zellers et al., 2019  ###reference_b60###  ###reference_b60###), 5-shot Winogrande (Sakaguchi et al., 2021  ###reference_b37###  ###reference_b37###) and 0-shot TruthfulQA (Lin et al., 2022  ###reference_b22###  ###reference_b22###).\nIn addition to comparing with LLaMA and MathLLaMA, we introduce Timo-SFT, which mirrors our framework in all aspects except for its training methodology.\nSpecifically, Timo-SFT is supervised fine-tuned with the chosen responses in the selected preference pairs.\nThe results are shown in Figure 9  ###reference_###  ###reference_###.\nWe surprisingly discover that Timo outperforms other baselines in the reasoning and general knowledge ability tasks.\nError analysis shows that our model aligns with the base model for 97% of the correct responses. This consistency indicates that our Timo effectively preserves general task knowledge, demonstrating remarkable generalization capabilities.\n###figure_11### ###figure_12### Time is a crucial dimension in our physical world (Lazaridou et al., 2021  ###reference_b19###  ###reference_b19###; Su et al., 2022  ###reference_b40###  ###reference_b40###; 2023  ###reference_b41###  ###reference_b41###; Zhao et al., 2024  ###reference_b62###  ###reference_b62###).

The reason might be due to the efficiency of our method, where a single iteration is sufficient for robust learning, and excessive training could instead diminish performance in temporal reasoning tasks."

To address concerns regarding the influence of the LLM-as-Judge framework compared to the use of a specialized math LLM, we conducted experiments using vanilla LLaMA2-7B and LLaMA2-7B-chat, representing general SFT LLaMA models.\nAs presented in Table 7  ###reference_###, our results demonstrate that incorporating a math LLM yields significant improvements in temporal reasoning tasks. Specifically, the math LLM outperforms the vanilla LLaMA2-7B and LLaMA2-7B-chat models by an average of 3.6 and 7 scores, respectively. The performance gains are especially notable in math-related tasks, where the math LLM achieves scores 5.5 and 10.5 scores higher than those of the other two models.\nThese results indicate that the math LLM component is crucial for enhancing temporal reasoning capabilities, outperforming the self-critic temporal optimization (i.e., LLM-as-Judge) framework alone. The results indicate that math-specific training plays a pivotal role in reasoning over time, confirming the value of specialized LLMs in complex reasoning tasks."

These datasets were selected to validate Timo\u2019s effectiveness across a broader range of temporal reasoning tasks.\nMCTACO: This dataset evaluates a wide range of commonsense knowledge related to events, including the duration, frequency, order, stationary nature, and typical timing of events.\nTempReason: This dataset emphasizes implicit temporal reasoning in structured facts, focusing on both event-time reasoning and event-event reasoning.\nThe results are shown in Table 8  ###reference_###. Timo achieves scores 6.2 and 15.5 points higher than LLaMA2-7B and WizardMath-7B on the TempReason task. Additionally, Timo surpasses MAmmoTH-7B by 19.3 points on the MCTACO task.\nThese results indicate that Timo excels across various temporal reasoning datasets, demonstrating its robust general temporal reasoning abilities.\nIn future work, We will further explore the generalization of Timo across more reasoning tasks, such as commonsense reasoning (Sakaguchi et al., 2021  ###reference_b37###), and composition relations reasoning (Zhao & Zhang, 2024  ###reference_b63###)."

The <span class=\"ltx_text ltx_font_smallcaps\" id=\"S8.p1.1.1\">Timo</span> model, trained within our proposed framework, indicates significant generalizability across 38 temporal tasks, establishing as the new SOTA model of comparable sizes.\nExtensive experiments further demonstrate the\neffectiveness of our framework in maintaining general task abilities.</p>\n</div>\n<section class=\"ltx_section\" id=\"Sx1\">\n<h2 class=\"ltx_title ltx_title_section\">Acknowledgement</h2>\n<div class=\"ltx_para ltx_noindent\" id=\"Sx1.p1\">\n<p class=\"ltx_p\" id=\"Sx1.p1.1\">We want to thank all the anonymous reviewers for their valuable comments.

+    "abstract": "The emergence of multilingual large language models has enabled the development of language understanding and generation systems in Azerbaijani. However, most of the production-grade systems rely on cloud solutions, such as GPT-4. While there have been several attempts to develop open foundation models for Azerbaijani, these works have not found their way into common use due to a lack of systemic benchmarking. This paper encompasses several lines of work that promote open-source foundation models for Azerbaijani. We introduce (1) a large text corpus for Azerbaijani, (2) a family of encoder-only language models trained on this dataset, (3) labeled datasets for evaluating these models, and (4) extensive evaluation that covers all major open-source models with Azerbaijani support.",

This boost has not been shared equally across different regions, however, mostly due to the slow osmosis of these technologies into low-resource languages. Azerbaijani language falls on the \"other\" side of this barrier, with its 24 million speakers worldwide.\nWhile some models have a limited understanding of the Azerbaijani language, only paid models offered by OpenAI have seen some level of adoption in the industry. Open-source models are being created with multilingual or Azerbaijani-only capabilities, but the community is not as keen to adopt them. This is possibly due to the limited exploration of these models\u2019 potential. This paper encompassed several lines of work that share a common goal - promoting open-source foundational models for Azerbaijani. Our contributions are as follows:\nDOLLMA: A new text corpus of 651.1 million words in Azerbaijani that can be used for pre-training LLMs.\naLLMA: A new family of BERT-class models trained on this dataset from scratch.\nThree labeled datasets that can be used for benchmarking foundation models in Azerbaijani:\nAZE-SCI: A text classification dataset.\nAZE-NSP: A next-sentence prediction dataset.\nCB-MCQ: A closed-book question-answering dataset.\nA benchmark for several natural language understanding (NLU) tasks in Azerbaijani.

These models have a disproportionately high number of trainable parameters, made possible due to the highly parallelizable nature of the transformer architecture. Their development takes place in two stages: Pre-training and fine-tuning. Pre-training is performed on Web-scale text corpora, while fine-tuning is performed on smaller and higher-quality data to adapt the model to a specific task. (Minaee et al., 2024  ###reference_b24###)\nFoundation models exist for various modalities, including language, vision, and speech. Language foundation models are usually classified as encoder, decoder, or encoder-decoder models. Encoder models are used for tasks that require language understanding, such as sentiment analysis and extractive question-answering. Encoder-decoder and decoder-only models are better suited for generative tasks, such as machine translation and text summarisation. Our work concentrates on encoder-only models. Our main inspiration is the BERT model family by (Devlin et al., 2019  ###reference_b10###) and its derivatives.\nIn the rest of the paper, a foundation model refers to a language model trained on a vast amount of unlabeled text data that can be fine-tuned for various downstream tasks. A large language model refers to a foundation language model with at least tens of millions of parameters."

+            "text": "The majority of LLMs are either monolingual English models or multilingual models that do not support Azerbaijani. Very few multilingual models support Azerbaijani, and only recently monolingual Azerbaijani models are beginning to emerge.\nThis slow progress can be explained by several factors. A smaller market and less investment is an obvious explanation, but the field faces more fundamental challenges that would not be immediately solved by more funding. One of these is the state of digitalization of the language. Most of the electronic books in Azerbaijani are scanned books. Only books published since the 1990s are written in the last version of the Azerbaijani Latin alphabet 111There was an older version of the Azerbaijani Latin alphabet introduced by the Soviets in 1922. This followed several variations until 1939 when the alphabet was replaced with a Cyrillic alternative. Azerbaijan started the transition to an updated Latin alphabet in 1991, which was completed in 2001., which creates another barrier. Yet another challenge is the small size of the community that\u2019s devoted to the development of open-source language models for Azerbaijani. The challenges regarding digitalization and script differences are further discussed in the third section.\nAn idea that is often heard regarding Azerbaijani LLMs is that we can simply go for the models developed for Turkish since languages are so similar. Azerbaijani and Turkish languages are not as similar as it is publicly perceived. According to (Salehi and Neysani, 2017  ###reference_b31###), Azerbaijanis scored 56% of receptive intelligibility in spoken Turkish. Differences in written language are not any smaller. Based on the methodology offered by (Gupta et al., 2019  ###reference_b13###), a 44% similarity score has been calculated between the vocabularies of the two languages 222https://www.ezglot.com/most-similar-languages?l=aze  ###reference_ges?l=aze###. Due to these significant differences, Turkish LLMs are not useful in machine learning tasks for Azerbaijani.\nThe paper is structured as follows. The next section gives a brief overview of previous works on foundational language models, and language modeling on Azerbaijani. The third section introduces DOLLMA, a new text corpus, and outlines the methodology, challenges we faced, and future works. The fourth section introduces aLLMA, a new family of monolingual encoder-only language models. The fifth section introduces several benchmarks for evaluating encoder-only Azerbaijani language models. These benchmarks are used to evaluate newly introduced models, as well as existing alternatives. The sixth section presents these benchmarks\u2019 results."

(Bengio et al., 2000  ###reference_b6###) and (Mikolov et al., 2010  ###reference_b23###) had created neural networks that outperformed traditional state-of-the-art model. (Schwenk et al., 2006  ###reference_b32###) uses neural networks for machine translation.\nThese models and their derivatives were task-specific. The idea of creating a foundational language model that could later be adapted (i.e., fine-tuned) to specific tasks was popularized only after the introduction of the transformer architecture by (Vaswani et al., 2017  ###reference_b36###). The earliest foundational language model that gained wide adoption was BERT by (Devlin et al., 2019  ###reference_b10###) and later variations like RoBERTa (Liu et al., 2019  ###reference_b21###).\nBERT was an encoder-only model, therefore more suitable for problems that could be formulated as a subset of the classification problem. Generative foundation models came out around the same time, in the example of\nGPT-1 (Radford and Narasimhan, 2018  ###reference_b27###), GPT-2 (Radford et al., 2019  ###reference_b28###), and T5 (Raffel et al., 2019  ###reference_b30###). While the GPT series continued with closed-source, enterprise models, other alternatives quickly emerged with superior performance. The most famous of these was the LLaMA series, which directly or indirectly resulted in the development of hundreds of open-source language models. (Touvron et al., 2023  ###reference_b35###).\nEarly foundation models were trained on English text, but multilingual models quickly emerged. Google had released multilingual BERT alternatives, and mGPT by (Shliazhko et al., 2023  ###reference_b33###) was an early variation of the GPT architecture for multiple languages. XLM-RoBERTa by (Conneau et al., 2020  ###reference_b9###) was a larger and more successful alternative to mGPT and was quickly adopted worldwide.\nXLM-RoBERTa was also one of the first (if not the first) foundation models that supported Azerbaijani. We are aware of only one academic work that has concentrated on the development of foundational language models for Azerbaijani. (Ziyaden et al., 2024  ###reference_b37###) have trained a RoBERTa model on the Azerbaijani split of the OSCAR dataset (Ortiz Su\u00e1rez et al., 2020  ###reference_b25###). This work is a first of its kind for Azerbaijani and a very valuable starting point. However, it does not concentrate on the development of a foundation model. Its main focus is improving model performance by text augmentation. Therefore, they do not perform a systematic evaluation of the model. They have released one RoBERTa model, without different sizes, which is yet another limiting factor in the adoption of the work. Unfortunately, this model has not been included in our evaluation benchmarks because they have not released a tokenizer that is compatible with their model.\nThere have also been some community attempts to create such open-source models. A series of RoBERTa models were developed by continuing the pre-training phase on a small Azerbaijani dataset (Hajili, 2024d  ###reference_b17###). Alas Development Center has developed a series of decoder-only LLMs for Azerbaijani 333https://github.com/interneuron-ai/project-barbarossa  ###reference_barbarossa###, but they offer no explanation regarding their approach, and the models failed to pass initial sanity checks."

For reference, GPT-2 and RoBERTa both were trained on OpenWebText (Liu et al., 2019  ###reference_b21###), consisting of 13.5 billion tokens, which is roughly equivalent to 10 billion words. Original BERT models were trained on 3.3. billion words. While these numbers have exploded in recent years, the success of these models suggests that similarly effective models can be trained on similarly sized datasets.\nThe largest corpora that existed at the beginning of our work were OSCAR, which contained 316 million words in Azerbaijani, and Colossal Clean Crawled Corpus (C4) with 1.7 billion words. Introduced by (Raffel et al., 2020  ###reference_b29###), C4 is one of the most widely used datasets in the pretraining stage of LLMs. C4 is labeled by language and contains 1.83 million documents tagged as Azerbaijani. Upon further inspection, however, we discovered a significant portion of this text is not only in different languages, but also in different alphabets (Armenian, Georgian, and Cyrillic). In addition, the C4 dataset contains a significant amount of informal text. This can be a valuable resource, but it is outside the scope of our work. Considering all of these points, we decided against using it. OSCAR (Ortiz Su\u00e1rez et al., 2020  ###reference_b25###) dataset is also derived from CommonCrawl. It suffers from the same problems, so it was not included in our corpus either.\nDue to these limitations, we decided to curate a new dataset specifically for pre-training LLMs that understand Azerbaijani. This new corpus is called DOLLMA (Dataset for Open Large Language Models in Azerbaijani).444https://huggingface.co/datasets/allmalab/DOLLMA  ###reference_OLLMA### The first and current version of this dataset contains Azerbaijani Wikipedia, Translated English Wikipedia (incomplete), news, blogs, books, and Azerbaijani laws. This dataset contains about 651.1 million words.555Words were counted with a simple whitespace tokenizer. New versions of DOLLMA will incorporate the Common Crawl data.\nBooks. We attempted to create a large book corpus but faced several challenges. Most of the available electronic books in Azerbaijani are scanned copies. Publishers rarely offer electronic books that are suitable for text extraction. As of 9 May 2024, Qanun Publishing, the largest publishing house in Azerbaijan, offers 52 PDFs or EPUBs on its website. The remaining books, which were sampled from the Azerbaijan National Library 666https://www.millikitabxana.az/  ###reference_www.millikitabxana.az/###, Children\u2019s Library 777https://www.clb.az/  ###reference_www.clb.az/###, and other sources, are all scanned copies that have occasionally passed through an OCR model. For OCR, Tesseract (Smith, 2007  ###reference_b34###) was chosen due to its multilingual support and open-source availability. We scanned thousands of books and manually sampled and analyzed them. Tesseract failed to capture guillemets, which is widespread in older Azerbaijani books. It also mixed up \"m\" with \"rn\" in scanned books. This happened often enough to decrease the quality of the text substantially. Due to these limitations, we decided against using OCR output altogether as training data. Instead, we opted for two datasets:\nBooks I contains a small number of handpicked books.\nBooks II contains a higher number of books with less detailed processing.\nWikipedia. We used dumps provided by the Wikimedia Foundation to create a new version of Azerbaijani Wikipedia. Both the data (aLLMA Lab, 2024d  ###reference_b4###) and cleaning scripts 888https://github.com/ceferisbarov/azwiki  ###reference_### are publicly available. BHOS AI team leads another initiative where they are using open-source translation models to translate English Wikipedia into Azerbaijani (BHOS AI R&D Center, 2024  ###reference_b8###). While this dataset offers little in terms of linguistic variety, it provides an invaluable knowledge base to train the models. Therefore, it was included in the final corpus.\nNews. There is an abundance of news datasets for Azerbaijani. However, we decided against using a very large news corpus, since it offers little variety in terms of language.\nIn our experience, models trained on news datasets do not learn the language comprehensively, possibly because the news contains little to no creative writing, first- and second-person narration, and dialogue. Due to these limitations, only two news datasets were included. One contains text scraped from several news platforms, and the other contains news and updates from Azerbaijan National Library. The BHOS AI team provided both datasets.\nBlogs. Another data source was blog posts collected from various websites. Instead of scraping a large number of websites for their blogs, several blogs were manually picked due to their high-quality text and informative content.\nLaws. The last part consisted of Azerbaijani laws, all of which are publicly available. We have also released this as an independent text corpus (aLLMA Lab, 2024e  ###reference_b5###).\nYou can see a summary of these sources and their accompanying upscaling ratios in Table 1  ###reference_###.\nUpscaling ratios were decided rather arbitrarily. We decided against upscaling the news since they offer little linguistic variety. Azerbaijani Wikipedia was upscaled higher than the translated English Wikipedia to account for the lossy translation process. Azerbaijani laws offer higher-quality text than Azerbaijani Wikipedia but offer less variety both in terms of content and form. Considering this, we upscaled them at the same level. Blogs and Books II datasets were hand-picked and constituted the highest-quality text in our corpus. Therefore, their upscaling ratio was the highest. Books II had mediocre quality, mostly due to the challenges of extracting text from PDF files. We upscaled it at the same level as the English Wikipedia.\nA major shortcoming of DOLLMA is imbalanced domain distribution. While the dataset contains a substantial amount of text on Azerbaijani laws, it is lacking in terms of first-person narrative, and STEM fields. It is also heavily Azerbaijan-centric, which may or may not be an issue depending on the final goal.\nDeduplication has not been performed since none of the sources has the potential of overlapping with another (i.e., Wikipedia and News, or Books and Laws). However, the addition of a deduplication stage is important if this corpus is to be expanded further.\nLater versions of DOLLMA will include several major changes:\nAdd deduplication to the pipeline. This will allow us to incorporate potentially overlapping text sources.\nCreate a large-scale book corpus.\nImprove domain distribution.\nIncorporate web-scraping datasets such as OSCAR and C4.\nWe believe that these changes will open up new possibilities for modeling the Azerbaijani language. At the current state, however, taking into account time and hardware limitations, our dataset was sufficient to continue to the modeling stage."

Base and large correspond to the original BERT models BERTBASE and BERTLARGE (Devlin et al., 2019  ###reference_b10###). Small architecture was borrowed from (Bhargava et al., 2021  ###reference_b7###). Architectural details of these models can be found in Table 2  ###reference_###.

While the benchmarks contain several models that have been trained with the former method, no detailed analysis of the performance difference is provided. This is left as a future research area.\nThe pre-training task was only masked language modeling. The next sentence prediction task constitutes one of our benchmarks but is not included in the pre-training stage. Training loss of aLLMA-Small and aLLMA-Base models can be found in Figure 1  ###reference_###.\nOne major limitation of the original BERT paper was static masking. If tokens are masked before the training process, then even with multiple epochs, the model will always have to predict the same token. We borrow the idea of dynamic masking from (Liu et al., 2019  ###reference_b21###). Instead of masking tokens before the training, tokens are masked on demand. This results in various masking patterns on the same text samples.\nSince our model is trained from scratch on an Azerbaijani-only dataset, using existing multilingual tokenizers offered no advantages. A WordPiece tokenizer121212https://huggingface.co/allmalab/bert-tokenizer-aze  ###reference_izer-aze### was trained on a weighted version of DOLLMA, with a vocabulary size of 64k. We have not performed a systematic evaluation to find the optimal vocabulary size. (Kaya and Tantu\u011f, 2024  ###reference_b20###) have researched the impact of vocabulary size on the performance of Turkish language models. Since both Azerbaijani and Turkish are agglutinative languages and share similar morphological features, we used the results of this research as a guide. While (Kaya and Tantu\u011f, 2024  ###reference_b20###) recommends increasing this number further, anything above that would be too computationally expensive for us.\n###figure_1###"

The final benchmark includes four model categories:\nMultilingual foundation models.\nBERT-Base-MULTI is a multilingual version of the original BERT model. XLM-RoBERTa-Base and XLM-RoBERTa-Large are some of the best-performing multilingual models (Conneau et al., 2020  ###reference_b9###). mDeBERTa-v3 is a multilingual version of DeBERTa v3 model (He et al., 2023  ###reference_b19###)).\nMultilingual models further pre-trained for Azerbaijani. BERT-Base-AZE (Hajili, 2024b  ###reference_b15###), RoBERTa-Base-AZE (Hajili, 2024d  ###reference_b17###), and mDEBERTA-v3-AZE (Hajili, 2024c  ###reference_b16###) have been further pre-trained on a small and high-quality Azerbaijani dataset. Their base models are RoBERTA-Base, BERT-Base-MULTI, and DeBERTa-Base, respectively.\nModels pre-trained from scratch.\naLLMA-Small, aLLMA-Base, and aLLMA-Large are the only monolingual Azerbaijani models.\nBaseline models. The original English-only BERT-Base was added as a baseline for the multilingual models. BERT-Scratch refers to the models trained on a specific task without pre-training weights. It functions as a baseline for all models in the benchmark.\nYou can find the results in Table 4  ###reference_###. mDeBERTa-v3 and aLLMA-Base have the best overall performance. Figure 2  ###reference_### compares the performance of Base models.131313The difference in number of parameters between these models is due to varying vocabulary sizes. Otherwise, their architectures are identical. aLLMA-Base outperforms all other models of similar size in 4 out of 6 benchmarks. Comparing BERT-Base-AZE with BERT-Base-MULTI shows that further pre-training of multilingual models can result in some performance improvement, but also model collapse (compare their performance in LDQuAd benchmark). However, a more comprehensive analysis is required before we can make generalizations about the effects of continued monolingual pre-training on multilingual models.\nBERT-Scratch performs particularly well on AZE-SCI, MRPC, and WikiANN tasks. We believe this has two explanations. The first is that these tasks can be solved partially with statistical information from the input text, while this is not possible with the other tasks. The second is that the random baseline in these tasks is relatively high, while SQuAD and LDQuAd have very low random baselines.\n###figure_2### These results demonstrate several points regarding foundation models for low-resource languages:\nPre-training from scratch on a monolingual dataset is a viable strategy for building a low-resource LLM. aLLMA-Base has competitive performance against larger models despite being trained only on the DOLLMA corpus.\nMultilingual models offer competitive performance even in languages that they were undertrained for. Azerbaijani has not been the focus in any of these multilingual models (XLM-RoBERTa, mDeBERTa-v3, or BERT-Base-MULTI). Despite this, they outperform most models in some tasks.\nEven monolingual English foundation models can be useful for fine-tuning on a downstream task and perform better than training a model from scratch. BERT-Base was included in our research as a baseline but exceeded our expectations. This suggests that the state-of-the-art English models can be utilized for certain NLU tasks in Azerbaijani. This remains a potential research area.\nIt is still possible that we have missed some high-quality models and we are open to feedback regarding this. Our work can be strengthened by finding or creating new benchmarks. We hope that this work will lay the foundations for such developments."

We tackle this issue by introducing a new family of foundation models for the language and benchmarking these models and other existing alternatives. To compensate for the lack of datasets suitable for benchmarking LLMs in Azerbaijani, we introduce text classification, closed-book question-answering, and next-sentence prediction datasets.\nThis work can be extended in several ways. The simplest improvement would be training larger models on larger corpora. Our project does not achieve this due to time and hardware limitations. aLLMA models are not a final product, but an early prototype. A larger training corpus, more advanced hardware, and a better-optimized training process will certainly result in more robust foundation models for Azerbaijani.\nA more urgent work, however, is extending the benchmarks by creating more labeled task-specific datasets and adding other existing models to the leaderboards.\nIncluding the next-sentence prediction task in the pre-training phase can increase the performance of aLLMA models further.\nAnother ambitious direction would be using our corpus to develop a generative foundation model. This paper concentrated on encoder-only models because it is a simpler problem to solve and it has more immediate applications. Nevertheless, generative language models have wide-ranging industrial applications and demand a systemic treatment."

In this work we focus on the \u201ckidnapped robot\u201d variant [3  ###reference_b3###], which strives to find the robot\u2019s location in an environment, with no prior information on its location, as opposed to fine-tuning the localization assuming we know generally where the robot is.\nIn a previous work [4  ###reference_b4###], we presented a method for performing robot localization in a planar (known) environment with only a few distance-measurements.\nHowever, environments may also contain dynamic disturbances, which do not appear in the known map of the environment, such as moved furniture, people walking around, other robots, etc. In this work, we present a general method for few distance-measurement localization, which is robust to such dynamic changes, both in theory and experiments."

The pose of the sensor when making the th distance measurement at time  is .\nAs shown in [4  ###reference_b4###], localization in a completely known environment can be effectively approximated.\nIf, a-priori we know exactly how  looks like, then that method [4  ###reference_b4###] would work as-is.\nObviously, in the presence of unknown obstacles, it could not be applied as-is.\nSee Figure 1  ###reference_### for an example.\n###figure_1### We focus here on workspaces that have a polygonal boundary, namely polygons or polygons with holes. Aiming for generality of the approach, we assume no prior knowledge on the topology, geometry, number or location of the dynamic obstacles. Of course we must make some assumptions on the dynamic obstacles in order for the problem to be solvable. Indeed, we make the following -dynamic sparsity assumption: We specify two natural numbers  and assume that out of a batch of  measurements, there would be at least  which measure the distance from the boundary of the known workspace .\nRemark.\nA trajectory  of a dynamic obstacle may be degenerate, in the sense that , i.e., for all  the obstacle stays put.\nFor simplicity, we refer to such unknown obstacles as dynamic as well."

+    "abstract": "We propose a novel change-point detection method based on online Dynamic Mode Decomposition with control (ODMDwC). Leveraging ODMDwC\u2019s ability to find and track linear approximation of a non-linear system while incorporating control effects, the proposed method dynamically adapts to its changing behavior due to aging and seasonality. This approach enables the detection of changes in spatial, temporal, and spectral patterns, providing a robust solution that preserves correspondence between the score and the extent of change in the system dynamics. We formulate a truncated version of ODMDwC and utilize higher-order time-delay embeddings to mitigate noise and extract broad-band features. Our method addresses the challenges faced in industrial settings where safety-critical systems generate non-uniform data streams while requiring timely and accurate change-point detection to protect profit and life. Our results demonstrate that this method yields intuitive and improved detection results compared to the Singular-Value-Decomposition-based method. We validate our approach using synthetic and real-world data, showing its competitiveness to other approaches on complex systems\u2019 benchmark datasets. Provided guidelines for hyperparameters selection enhance our method\u2019s practical applicability.",

+            "text": "Many industrial systems are safety-critical, where process monitoring is essential to protect both profit and life. These systems operate at various operating points, often driven by control to meet desired production goals. However, environmental fluctuations and varying component quality may lead to unexpected and persistent changes in system behavior. These events can jeopardize optimal operations, accelerate wear and tear, and occasionally result in catastrophic consequences, such as equipment damage, production loss, or even human casualties.\nMonitoring abrupt and gradual changes in system behavior is crucial for ensuring system reliability and safety, a task known as change-point detection (CPD). Traditional system monitoring methods, like Statistical Process Control (SPC), rely on the assumption that data are independent and identically distributed (i.i.d.), which is often not the case in industrial systems. Industrial process data are typically correlated and non-stationary, complicating the application of SPC methods. While SCADA-based systems do not rely on i.i.d. and use static thresholds to detect changes, they cannot adapt to the dynamic changes in system behavior due to aging or environmental shifts.\nConventionally, offline machine learning (ML) methods are employed to identify macro-scale events in complex, high-dimensional dynamical systems. These methods depend on extensive historical data and require offline training to detect system behavior changes. Although supervised ML methods with annotated data offer high accuracy, they often fail in new contexts or when encountering unexpected data patterns. Moreover, these methods are impractical for existing industrial infrastructures where storing data on a large scale is infeasible due to undeveloped database infrastructure, and direct integration with ongoing data exchange services is necessary.\nIndeed, industrial data are streamed and arrive at non-uniform rates, challenging methods dependent on uniform sampling. For instance, Liu et al. (2023  ###reference_b31###) simultaneously detecting change points and anomalies by leveraging the rate of change, and Fathy et al. (2019  ###reference_b11###) using cooperative adaptive filtering for change detection in wireless sensor networks both assume i.i.d. Therefore, these methods may not be suitable for non-uniform data streams typical in industrial settings.\nAdditionally, sequential data in industrial systems comprise distinct components: linear, seasonal, cyclic, regressions, interventions, and errors. Effective CPD methods must adapt to these changing conditions over the system\u2019s lifetime. Further consideration must be given to the type of change point we wish to detect. Variance change points affect more significant segments of time series, while additive change points are sudden pulses that die out quickly, and innovational change points are followed by gradual decay back to the original time series (Srivastava et al., 2017  ###reference_b40###).\nThis paper provides a unified methodology to answer questions that arise:\nCan we detect changes in system behavior using streaming data?\nHow can changes be detected in the presence of non-stationarity?\nCan we adapt to changing system behavior to maintain validity over the system\u2019s lifetime?"

+            "text": "Online CPD methods address these questions, which are central for real-time monitoring in safety-critical industrial systems. Unlike offline CPD methods, which typically provide robust detection with significant delay, online CPD offers real-time solutions essential for timely intervention and maintenance planning. Indeed, offline methods often retrospect the historical data and detect changes in the system behavior after the event has occurred. In some settings, this may be acceptable, and favorable properties of offline methods might be enjoyed. For example, Liu et al. (2022  ###reference_b29###) developed a CPD framework using a dynamic Bayesian network model to capture causal relationships between variables, enhancing interpretability and credibility. However, in industrial environments, real-time monitoring is imperative to prevent production losses or catastrophic outcomes such as equipment failure.\nSelf-supervised approaches are frequently used in online CPD due to the impracticality of obtaining real-time ground truth annotations. However, they still rely on annotations to create a feedback loop. These may be available from other online subsystems that may provide labels for continually supervised approaches to CPD, such as Korycki and Krawczyk (2021  ###reference_b26###). In most cases, the supervisory information is exploited directly from the raw unlabeled data, showing improved generalization abilities (Zhang et al., 2024  ###reference_b47###).\nChu and Chen (2022  ###reference_b7###) propose a sequential nearest neighbor search for high-dimensional and non-Euclidean data streams. A stopping rule is proposed to alert detected CP as soon as it occurs while providing a maximum boundary on a number of false positives. Despite its innovation, the sensitivity of nearest neighbors methods to varying data densities and computational expense in high-dimensional spaces restricts its real-time applicability.\nGupta et al. (2022  ###reference_b17###) proposed a three-phase architecture for real-time CPD using autoencoders (AE). However, the necessary preprocessing steps, such as shifting and scaling, require assumptions about data distribution that are often unknown in streaming scenarios. Additionally, recursive singular spectrum analysis, employed in the architecture, may impose significant computational overhead in the case of high-dimensional data.\nBao et al. (2024  ###reference_b2###) proposes feature decomposition and contrastive learning (CoCPD) for industrial time series to detect both abrupt CPs and subtle changepoints. By isolating predictable components from residual terms, this method improves detection accuracy in detecting subtle changes. Contrastive learning methods rely on constructing negative samples to increase the energy of the change points and decrease the energy of the stationary operation data. Nevertheless, this is one of the main bottlenecks of contrastive learning methods. Since changes are unpredictable events that differ in sources and nature, it is challenging to generate negative samples to capture this variability as the prior information on the magnitudes and timing distributions are unknown, and the space of negative samples is therefore unbounded.\nEstablished statistical CPD methods promote interpretability while remaining highly competitive. Rajaganapathy et al. (2022  ###reference_b36###) introduced a Bayesian network-based CPD method, which is able to capture CPs characterized by step change leveraging causal relationships between the variables. Nevertheless, as we will explore soon, the change point may be characterized by a change in dynamics, which is better captured in the frequency domain rather than in the time domain.\nAnother common practice in CPD is to compare past and future time series intervals using a dissimilarity measure, triggering alarms when intervals are sufficiently different. Statistical CPD methods usually compare the relative statistical differences between time intervals to identify change points (CPs). Temporal properties such as data distribution and time series models should be accurately modeled in advance to obtain more precise statistical metrics for evaluating interval homogeneity. Methods in this group define this dissimilarity measure based on the difference in distribution of the two intervals. For instance, CUSUM and related methods Ye et al. (2023  ###reference_b44###) track changes in the parameter of a chosen distribution, and the generalized likelihood ratio (GLR) procedure Xie et al. (2013  ###reference_b43###); Korycki and Krawczyk (2021  ###reference_b26###) monitors the likelihood that both intervals are generated from the same distribution. Subspace-based methods measure the distance between subspaces spanned by the columns of an observability matrix Moskvina and Zhigljavsky (2003  ###reference_b32###); Kawahara et al. (2007  ###reference_b24###) or observe reconstruction error (De Ryck et al., 2021  ###reference_b9###; Bao et al., 2024  ###reference_b2###). Here, we will use subspace-based methods as an umbrella term for decomposition and deep neural network methods, which rely on finding the low-dimensional description of the data."

+            "text": "The main advantages of subspace-based approaches include the absence of distributional assumptions and their ability to extract complex dynamical features from data efficiently. For example, Hirabaru et al. (2016  ###reference_b19###) might be a powerful example of cost-effectiveness in high-dimensional systems. The authors find a 1D subspace within multidimensional data and apply efficient univariate CPD, expanding their applicability to multivariate scenarios. This operates under the same assumption as Fathy et al. (2019  ###reference_b11###) that the measurements are closely related and enable 1D representation to capture the signal from the noise. Nevertheless, these approaches are not suitable for complex systems characterized by multiple weakly related quantities whose behavior cannot be captured solely by the largest eigenvalue.\nWhile some ML-based transformers demonstrate the ability to adapt and generalize to new data while retaining useful information over prolonged deployments (Corizzo et al., 2022  ###reference_b8###), they lack guarantees that the CPD score accurately reflects the actual dissimilarity between intervals. This issue, highlighted by De Ryck et al. (2021  ###reference_b9###), can lead to misjudgments about the severity of change points and result in poor decision-making. Additionally, subspace-based methods are sensitive to hyperparameter choices, often lacking informed guidance.\nSubspace-based methods address these limitations by monitoring whether incoming data aligns with the null space of the reference state\u2019s observability matrix, effectively identifying new operating states (D\u00f6hler and Mevel, 2013  ###reference_b10###; Ye et al., 2023  ###reference_b44###). Xie et al. (2013  ###reference_b43###) leverage this principle in the MOUSSE (Multiscale Union of Subsets Model) algorithm, which tracks dynamic submanifolds in high-dimensional noisy data using a sequential generalized likelihood ratio procedure for CPD.\nNumerous theoretical studies support the optimality of subspace-based methods in CPD. For instance, Ye et al. (2023  ###reference_b44###) derive an exact subspace-CUSUM procedure and characterize average run length (ARL) and Type-II error probability using asymptotic random matrix theory, optimizing metrics such as expected detection delay (EDD). Similarly, Garreau and Arlot (2018  ###reference_b14###) demonstrate that a kernel change-point algorithm can, with high probability, correctly identify the number and location of change points under well-chosen penalties and estimate the change-point location at the optimal rate.\nSuccessful practical applications complement the solid theoretical foundation of these methods. For instance, Hosur and Duan (2019  ###reference_b20###) address the need for near real-time detection of changes in power systems\u2019 working conditions with a sequential detection algorithm based on stochastic subspace state-space identification, utilizing output-only covariance-based subspace identification with Hankel matrices. D\u00f6hler and Mevel (2013  ###reference_b10###) propose a robust residual function for detecting changes in the eigenstructure of linear time-invariant systems for vibration monitoring. He et al. (2019  ###reference_b18###) introduce ADMOST, an online subspace tracking framework similar to online SVD updated without increasing the rank, displaying its applicability to real-time UAV flight data, where anomaly detection and mitigation are required."

Addressing this issue requires decomposing a time series into its dominant frequency components, which are described by oscillations and magnitudes. For example, De Ryck et al. (2021  ###reference_b9###) combined detection in both domains using two autoencoders in the TIRE method, leveraging discrete Fourier Transformation to extract spectral information. Similarly, Gupta et al. (2022  ###reference_b17###) utilized recursive singular spectrum analysis in preprocessing within an autoencoder-based CPD framework to decompose time series into dominant frequency components. However, this approach requires retraining the model after each predicted change point, which is computationally expensive and unsuitable for real-time applications.\nDynamic Mode Decomposition (DMD) emerges as a suitable method for CPD in both the time and frequency domain. DMD is a data-driven technique that decomposes a time series into its dominant frequency components (modes), described by their oscillation and magnitudes. By approximating the dynamical system through a linear combination of these modes, DMD facilitates interpretable CPD concerning system dynamics. It allows for monitoring changes in spatial features and system dynamics and detecting changes arising from environmental factors.\nSupporting this claim, Prasadan and Nadakuditi (2020  ###reference_b34###) applied DMD to a data matrix composed of linearly independent, additive mixtures of latent time series, focusing on missing data recovery. They demonstrated that hankelized DMD, a higher-lag extension of DMD, could unmix signals, revealing them better in noise and offering superior reconstruction compared to Principal Component Analysis (PCA) and Independent Components Analysis (ICA).\nIn another study, Srivastava et al. (2017  ###reference_b40###) introduced an innovative offline algorithm leveraging DMD to detect variance change points iteratively. Their method integrates a data-driven dynamical system with a local adaptive window guided by a variance descriptor function, facilitating the identification of change points at various scales. By employing sequential hypothesis testing and a dynamic window mechanism, the method dynamically adjusts the window\u2019s location and size to detect changes in variance. This offline algorithm performs multiple passes over the data first to identify the longest stationary segments and then detect variance change points, making it unsuitable for real-time applications.\nSimilarly, Gottwald and Gugole (2020  ###reference_b15###) focused on detecting transient dynamics and regime changes in time series using DMD. They argued that transitions between different dynamical regimes are often reflected in higher-dimensional space, followed by relaxation to lower-dimensional space. They proposed using the reconstruction error of DMD to monitor a time series\u2019 inability to resolve fast relaxation towards the attractor and the system dynamics\u2019 effective dimension."

The DMD was found to be closely related to Koopman theory by Rowley et al.

Transient dynamics, in particular, cannot be adequately captured by the low-rank subspace (Kuehn, 2011  ###reference_b27###; Gottwald and Gugole, 2020  ###reference_b15###). Therefore, a valid selection of the subspace maximizes the reconstruction error for non-stationary signals and is crucial for its use in CPD (Moskvina and Zhigljavsky, 2003  ###reference_b32###).\nLong-term deployment in systems with time-varying characteristics connected to factors such as aging, wear, or environmental conditions necessitates sequential detection and updates to the subspace in a streaming manner. This allows the system to adapt to slow changes in the time series structure and to accommodate new operations that may persist for an undefined duration. The ODMD-CPD algorithm is designed to address these challenges, providing a robust and adaptive solution for CPD in time series data.\nFirstly, when new snapshots are available, CPD-DMD updates the low-rank subspace over which the signal evolves. Secondly, the algorithm projects two stored windows of snapshot pairs, referred to as base and test matrices, onto the subspace to evaluate the reconstruction error.

The initial part of this section compares the proposed method with a related method for change point detection based on subspace identification using online SVD. Artificial step detection highlights the significant differences in identifying subspaces using the two decomposition methods. Two real-world datasets are used to compare the performance of our proposed method with that of the alternative subspace identification method.\nSecondly, we address the challenging real-world dataset involving faulty HVAC operation detection in an industrial-scale battery energy storage system (BESS). The final subsection compares the proposed method with other methods used for change-point detection on benchmarking data of a simulated complex dynamical system with control (CATS) and a laboratory water circulation system (SKAB).\nIn this paper, we proposed truncation of online Dynamic Mode Decomposition with control and examined its efficacy in online subspace-based change point detection tasks. The approximation of subspace over which a complex system (possibly a non-linear time-varying controlled system with delays) evolves is traced using time-delayed embeddings created directly from the system\u2019s input-output non i.i.d. streaming data. DMD enables the decomposition of the system\u2019s dynamics into a set of modes that can be used to reconstruct signals from the data, which are subject to noise and carry information about abrupt changes. The similarity of the original data to its reconstruction is evaluated over two windows: reference and test. The former establishes base reconstruction error, and the latter, which includes the latest snapshots provided by the streaming service, is evaluated for the presence of a change point. The size of the test window defines the delay of the peak CPD statistics, as shown on the synthetic dataset, and defines the maximum delay of the alarm under the assumption that the error crosses the selected threshold. The tradeoff between detection speed and the number of false positives can be tuned by changing this parameter. Although setting generally applicable default values of the proposed method\u2019s hyperparameters is impossible, we establish intuitive guidelines for their selection. We also show that while computing CPD statistics on error ratio reveals minor change points close to the origin, error divergence can be used to acquire statistics proportional to the actual difference. In the case study displaying real-world examples of faulty HVAC operation detection in BESS, we observe that the height of difference of the errors is proportional to the distance of the faulty state from normal operation. This is crucial for assessing the severity of deviations in the operation of industrial systems, which is relevant in overall risk assessment. In contrast, the error ratio hints at potential precursors of the transition towards the faulty operation.

This decrease can be explained by the significant increase in absolute error between the original and reconstructed data for both the base and test sets, compared to their relative error, which decreases the residual of their division. Computing the difference between test and base set reconstruction errors gives evidence to the previous explanation. This relation of energy of the change-point detection to the actual dissimilarity of the data is a significant advantage of the proposed method over the deep learning techniques (De Ryck et al., 2021  ###reference_b9###).

While the SVD-based method detects all the change points as well, noisy CPD statistics may hinder the recognition of another change point regarding linear trends, which may be observed more often in real scenarios due to the aging of the device and seasonal effects.\n###figure_6###"

The studied BESS has an installed capacity of 151 kWh distributed among ten modules with 20 Li-ion NMC cells. A hardware fault occurred on one of the module\u2019s cooling fans on 23rd August 2023 at 17:12:30. To protect the profitability of the BESS for the end user, the faulty BESS was operated securely until the fault was fixed. This case study aims to detect the transition from normal to faulty operation of the HVAC system based on temperature profile monitoring. The dataset is provided by the BESS operator and normalized to protect sensitive business information. It captures snapshots of six spatially distributed temperature sensors of the targeted BESS module operation at approximately 30-second intervals.\nThe selection of hyperparameters demonstrates the intuitiveness of parameter selection. The BESS is utilized in an industrial setting for availability time-shifting of energy generated by a solar power plant, subject to daily seasonality and weekly periodicity. The learning window  is set for 24 hours to reflect these patterns and track weekday and weekend operations well. The maximum C-rate of the BESS is 1.0, defining another important hourly time constant. With this knowledge, we can minimize the impact of charging events on change-point detection statistics;  and  window sizes are set to double the fastest charging rate, 240 samples, corresponding to 2 hours of operation. The number of time delays in the embedded matrix reflects the known dynamics of the system; hence,  is set to 240 samples.\nThe results of the detection experiment on simulated data streaming from the BESS history replay, presented in Figure 7  ###reference_###, show that before the actual occurrence of the fault, the system detects multiple events of abnormal operation with a source other than the identified dynamical system from the data. The proposed method accurately detects the transition from normal to faulty operation of the HVAC system with high accuracy and low false positive rate, with the peak of change-point statistics delayed by  snapshots.\nThe proposed method detected three periods related to the transient normal behavior of the HVAC system, marked as change points. While it is challenging to confirm if the initial peaks in the CPD score were false positives, operators can interpret this information as a potential early warning of an impending fault. Such early warnings are valuable for detecting faults, preventing catastrophic consequences, and planning maintenance. The positions of the potential fault precursors match the detected anomalies in Wadinger and Kvasnica (2024  ###reference_b42###), where detection was performed using an online anomaly detection method based on conditional probability distribution. This alignment supports cross-validation of both methods and lends credibility to identifying these events as fault precursors.\nThe evaluation of error difference shows that we can detect both the transition from normal to faulty operation and vice versa. Here, the peaks related to true anticipated CPs are more pronounced than those in the error ratio evaluation. This indicates the usefulness of the error difference evaluation in increasing the precision of the CPD.\n###figure_7###"

The dataset represents a well-described industrial system with multiple sensors and well-defined operational and fault states characterized by collective anomalies or change points, as well as transitions between these states.\nKatser and Kozitsin (2020  ###reference_b23###) compare methods with default hyperparameters, which are listed in Table 2  ###reference_###, using the first 400 snapshots of each dataset as a training part. We follow the same procedure, and for CPD-DMD hyperparameters with task-specific tuning requirements, we use the training set of samples as a history of snapshots to establish the parameters.\nThe evaluation is performed using NAB metrics presented in the work of Ahmad et al. (2017  ###reference_b1###). These metrics operate over a window of snapshots. In the leaderboard proposed in Katser and Kozitsin (2020  ###reference_b23###), the window is centered around the change point to establish metrics for reference methods. Nevertheless, from the definition of the change-point and the utilization of the window for scoring (please refer to the paper by Lavin and Ahmad (2015  ###reference_b28###)), it is evident that the detector alerting a change-point half of the window size snapshots before the change-point actually occurs is considered perfect. Since the start of the transition towards the faulty state is marked as anomalous in the dataset, as seen in Figure 8  ###reference_###, we stipulate that the detection before the start of the transition should be regarded as a false positive. Therefore, we modify the original evaluation metrics to observe the snapshots window after the change-point and evaluate the models\u2019 performance.\nTo ensure reproducibility and consistency, we created a fork of the original repository available at https://github.com/MarekWadinger/SKAB  ###reference_###.\n###figure_8### The results of experiments, presented in Table 4.5  ###reference_###, show that the proposed method outperforms the reference methods in terms of standard NAB score, low FP, and low FN scores. Our proposed method and MSCRED have the lowest number of missed change points, making them more suitable methods for safety-critical systems where missed alarms may result in catastrophic consequences. Two variants of the proposed method are evaluated to show the influence of threshold  selection. Based on the results, we claim that the selection of threshold value, which is challenging for non-probabilistic approaches to CPD where CPD statistics have no proper normalization, may improve the FP score but does not significantly impact performance. Thus, this difficult-to-select parameter can initially be set to 0 and then increased to improve the false positive score when dealing with signals that are hard to reconstruct due to significant noise. Perhaps most interesting is the score of the perfect detector, which is not 100 as expected. This indicates that the standard NAB score does not guarantee a 100 for a perfect detector for various evaluation criteria, which is essential to consider when evaluating the relative performance of the methods with respect to the perfect detector under these criteria.\nThis section evaluates the performance of our method on the Controlled Anomalies Time Series (CATS) Dataset proposed in Fleith (2023  ###reference_b13###). The dataset shows a simulation of a complex dynamical system with 200 injected anomalies, consisting of control commands, external stimuli, and 5 million snapshots of telemetry sampled at 1 Hz. While the generating mechanism is not described, the availability of the benchmark dataset, including the control action signals, makes it a good candidate for evaluating the proposed method. The dataset is meant for anomaly detection algorithms but contains numerous sequences of anomalous behavior. Compared to SKAB, this dataset has a far lower contamination level of 3.8%, making it more suitable for evaluating the CPD performance, where events of change are underrepresented.\nThe evaluation uses the same metrics as the previous case study on a resampled dataset to 1-minute intervals, with a median taken for both features and targets. No public background on the generating mechanism complicated the hyperparameter selection. Based on the 58-day timespan captured in the dataset, we selected one day as the learning window and set the number of time delays to 4 hours, with a maximum limit of the final number of features set to 60. The reference window is double the size of the test window, 10 hours for the former and 5 hours for the latter. The ranks of the DMD were set to 10 and 4 for the states and control inputs, respectively.\nThe results of experiments, presented in Table 4.6  ###reference_###, show that the proposed method outperforms all reference methods but MSCRED in terms of the standard NAB score evaluated on a 5-hour window starting to the right of the actual anomaly. While our method offers a significantly better FP score, reducing the number of false alarms, MSCRED offers a significantly better FN score. It is worth stating that while our proposed method and other reference methods completed the experiment within 1 hour, it took almost 24 hours for MSCRED. This means that it requires roughly one second per snapshot to process the data, which could challenge MSCRED\u2019s applicability in hard real-time scenarios with the original frequency of 1 Hz. In the given settings, our proposed method balances well between false positives and false negatives, with the lowest number of missed change points. The results indicate that the proposed method is capable of detecting change points in the complex dynamical system and can employ information about control inputs."

+            "text": "In this paper, we proposed truncation of online Dynamic Mode Decomposition with control and examined its efficacy in online subspace-based change point detection tasks. The approximation of subspace over which a complex system (possibly a non-linear time-varying controlled system with delays) evolves is traced using time-delayed embeddings created directly from the system\u2019s input-output non i.i.d. streaming data. DMD enables the decomposition of the system\u2019s dynamics into a set of modes that can be used to reconstruct signals from the data, which are subject to noise and carry information about abrupt changes. The similarity of the original data to its reconstruction is evaluated over two windows: reference and test. The former establishes base reconstruction error, and the latter, which includes the latest snapshots provided by the streaming service, is evaluated for the presence of a change point. The size of the test window defines the delay of the peak CPD statistics, as shown on the synthetic dataset, and defines the maximum delay of the alarm under the assumption that the error crosses the selected threshold. The tradeoff between detection speed and the number of false positives can be tuned by changing this parameter. Although setting generally applicable default values of the proposed method\u2019s hyperparameters is impossible, we establish intuitive guidelines for their selection. We also show that while computing CPD statistics on error ratio reveals minor change points close to the origin, error divergence can be used to acquire statistics proportional to the actual difference. In the case study displaying real-world examples of faulty HVAC operation detection in BESS, we observe that the height of difference of the errors is proportional to the distance of the faulty state from normal operation. This is crucial for assessing the severity of deviations in the operation of industrial systems, which is relevant in overall risk assessment. In contrast, the error ratio hints at potential precursors of the transition towards the faulty operation. The proposed method is highly competitive, as shown on two benchmark datasets of a simulated complex system and a real laboratory system.\nOur code and data are openly accessible on GitHub at the following URL: https://github.com/MarekWadinger/odmd-subid-cpd  ###reference_d-cpd###  ###reference_d-cpd###.\nMarek Wadinger: Conceptualization; Data curation; Formal analysis; Funding acquisition; Investigation; Methodology; Resources; Software; Validation; Visualization; Writing \u2014 original draft; and Writing \u2014 review & editing.

ltx_citemacro_citet\">Fleith (<a class=\"ltx_ref\" href=\"https://arxiv.org/html/2407.05976v2#bib.bib13\" title=\"\">2023  ###reference_b13###  ###reference_b13###</a>)</cite>. The dataset shows a simulation of a complex dynamical system with 200 injected anomalies, consisting of control commands, external stimuli, and 5 million snapshots of telemetry sampled at 1 Hz. While the generating mechanism is not described, the availability of the benchmark dataset, including the control action signals, makes it a good candidate for evaluating the proposed method. The dataset is meant for anomaly detection algorithms but contains numerous sequences of anomalous behavior. Compared to SKAB, this dataset has a far lower contamination level of 3.8%, making it more suitable for evaluating the CPD performance, where events of change are underrepresented.</p>\n</div>\n<div class=\"ltx_para\" id=\"S4.SS6.p2\">\n<p class=\"ltx_p\" id=\"S4.SS6.p2.1\">The evaluation uses the same metrics as the previous case study on a resampled dataset to 1-minute intervals, with a median taken for both features and targets. No public background on the generating mechanism complicated the hyperparameter selection. Based on the 58-day timespan captured in the dataset, we selected one day as the learning window and set the number of time delays to 4 hours, with a maximum limit of the final number of features set to 60. The reference window is double the size of the test window, 10 hours for the former and 5 hours for the latter. The ranks of the DMD were set to 10 and 4 for the states and control inputs, respectively.</p>\n</div>\n<div class=\"ltx_para\" id=\"S4.SS6.p3\">\n<p class=\"ltx_p\" id=\"S4.SS6.p3.1\">The results of experiments, presented in Table\u00a0<a class=\"ltx_ref\" href=\"https://arxiv.org/html/2407.05976v2#S4.SS6\" title=\"4.6 Simulated Complex Dynamical System with Control (CATS) \u2023 4.5 Laboratory Water Circulation System (SKAB) \u2023 4 Results \u2023 Change-Point Detection in Industrial Data Streams based on Online Dynamic Mode Decomposition with Control\">4.6  ###reference_###  ###reference_###</a>, show that the proposed method outperforms all reference methods but MSCRED in terms of the standard NAB score evaluated on a 5-hour window starting to the right of the actual anomaly. While our method offers a significantly better FP score, reducing the number of false alarms, MSCRED offers a significantly better FN score. It is worth stating that while our proposed method and other reference methods completed the experiment within 1 hour, it took almost 24 hours for MSCRED. This means that it requires roughly one second per snapshot to process the data, which could challenge MSCRED\u2019s applicability in hard real-time scenarios with the original frequency of 1 Hz. In the given settings, our proposed method balances well between false positives and false negatives, with the lowest number of missed change points. The results indicate that the proposed method is capable of detecting change points in the complex dynamical system and can employ information about control inputs.</p>\n</div>\n<figure class=\"ltx_table\" id=\"S4.SS6.38\">\n<figcaption class=\"ltx_caption\"><span class=\"ltx_tag ltx_tag_table\">Table 4: </span>Comparison of different algorithms based on NAB metrics.

</span>Conclusions</h2>\n<div class=\"ltx_para\" id=\"S5.p1\">\n<p class=\"ltx_p\" id=\"S5.p1.1\">In this paper, we proposed truncation of online Dynamic Mode Decomposition with control and examined its efficacy in online subspace-based change point detection tasks. The approximation of subspace over which a complex system (possibly a non-linear time-varying controlled system with delays) evolves is traced using time-delayed embeddings created directly from the system\u2019s input-output non i.i.d.\u00a0streaming data. DMD enables the decomposition of the system\u2019s dynamics into a set of modes that can be used to reconstruct signals from the data, which are subject to noise and carry information about abrupt changes. The similarity of the original data to its reconstruction is evaluated over two windows: reference and test. The former establishes base reconstruction error, and the latter, which includes the latest snapshots provided by the streaming service, is evaluated for the presence of a change point. The size of the test window defines the delay of the peak CPD statistics, as shown on the synthetic dataset, and defines the maximum delay of the alarm under the assumption that the error crosses the selected threshold. The tradeoff between detection speed and the number of false positives can be tuned by changing this parameter. Although setting generally applicable default values of the proposed method\u2019s hyperparameters is impossible, we establish intuitive guidelines for their selection. We also show that while computing CPD statistics on error ratio reveals minor change points close to the origin, error divergence can be used to acquire statistics proportional to the actual difference. In the case study displaying real-world examples of faulty HVAC operation detection in BESS, we observe that the height of difference of the errors is proportional to the distance of the faulty state from normal operation. This is crucial for assessing the severity of deviations in the operation of industrial systems, which is relevant in overall risk assessment. In contrast, the error ratio hints at potential precursors of the transition towards the faulty operation. The proposed method is highly competitive, as shown on two benchmark datasets of a simulated complex system and a real laboratory system.</p>\n</div>\n<section class=\"ltx_section\" id=\"Sx1\">\n<h2

</span>Conclusions</h2>\n<div class=\"ltx_para\" id=\"S5.p1\">\n<p class=\"ltx_p\" id=\"S5.p1.1\">In this paper, we proposed truncation of online Dynamic Mode Decomposition with control and examined its efficacy in online subspace-based change point detection tasks. The approximation of subspace over which a complex system (possibly a non-linear time-varying controlled system with delays) evolves is traced using time-delayed embeddings created directly from the system\u2019s input-output non i.i.d.\u00a0streaming data. DMD enables the decomposition of the system\u2019s dynamics into a set of modes that can be used to reconstruct signals from the data, which are subject to noise and carry information about abrupt changes. The similarity of the original data to its reconstruction is evaluated over two windows: reference and test. The former establishes base reconstruction error, and the latter, which includes the latest snapshots provided by the streaming service, is evaluated for the presence of a change point. The size of the test window defines the delay of the peak CPD statistics, as shown on the synthetic dataset, and defines the maximum delay of the alarm under the assumption that the error crosses the selected threshold. The tradeoff between detection speed and the number of false positives can be tuned by changing this parameter. Although setting generally applicable default values of the proposed method\u2019s hyperparameters is impossible, we establish intuitive guidelines for their selection. We also show that while computing CPD statistics on error ratio reveals minor change points close to the origin, error divergence can be used to acquire statistics proportional to the actual difference. In the case study displaying real-world examples of faulty HVAC operation detection in BESS, we observe that the height of difference of the errors is proportional to the distance of the faulty state from normal operation. This is crucial for assessing the severity of deviations in the operation of industrial systems, which is relevant in overall risk assessment. In contrast, the error ratio hints at potential precursors of the transition towards the faulty operation. The proposed method is highly competitive, as shown on two benchmark datasets of a simulated complex system and a real laboratory system.</p>\n</div>\n<section class=\"ltx_section\" id=\"Sx1\">\n<h2

+    "abstract": "Different from human nature, it is still common practice today for vision tasks to train deep learning models only initially and on fixed datasets. A variety of approaches have recently addressed handling continual data streams. However, extending these methods to manage out-of-distribution (OOD) scenarios has not effectively been investigated. On the other hand, it has recently been shown that non-continual neural mesh models\nexhibit strong performance in generalizing to such OOD scenarios.\nTo leverage this decisive property in a continual learning setting, we propose incremental neural mesh models that can be extended with new meshes over time. In addition, we present\na latent space initialization strategy that enables us to allocate feature space for future unseen classes in advance and a positional regularization term that forces the features of the different classes to consistently stay in respective latent space regions. We demonstrate the effectiveness of our method through extensive experiments on the Pascal3D and ObjectNet3D datasets and show that our approach outperforms the baselines for classification by  in the in-domain and by  in the OOD setting. Our work also presents the first incremental learning approach for pose estimation.\nOur code and model can be found at github.com/Fischer-Tom/iNeMo.",

+            "text": "###figure_1### Humans inherently learn in an incremental manner, acquiring new concepts over time, with little to no forgetting of previous ones. In contrast, trying to mimic the same behavior with machine learning suffers from catastrophic forgetting [37  ###reference_b37###, 38  ###reference_b38###, 22  ###reference_b22###], where learning from a continual stream of data can destroy the knowledge that was previously acquired. In this context, the problem was formalized as class-incremental learning and a variety of approaches have been proposed to address catastrophic forgetting for models that work in-distribution [27  ###reference_b27###, 12  ###reference_b12###, 18  ###reference_b18###, 46  ###reference_b46###, 32  ###reference_b32###, 31  ###reference_b31###]. However, extending these methods to effectively manage out-of-distribution (OOD) scenarios [65  ###reference_b65###] to the best of our knowledge has not been investigated.\nNeural mesh models [53  ###reference_b53###] embed 3D object representations explicitly into neural network architectures, and exhibit strong performance in generalizing to such OOD scenarios for classification and 3D pose estimation. However, as they consist of a 2D feature extractor paired with a generative model, their extension to a continual setting with existing techniques is not straight forward.\nIf one would only apply those techniques to the feature extractor, the previously learned neural meshes would become inconsistent and the performance of the model would drop.\nIn this paper, we therefore present a strategy to learn neural mesh models incrementally and refer to them as incremental Neural Mesh Models (iNeMo). As shown in Figure 1  ###reference_###,\nin addition to the conventional techniques of knowledge distillation and maintaining a replay buffer, our approach introduces a memory that contains a continuously growing set of meshes that represent object categories. To establish the learning of the meshes in an incremental setting, we extend the contrastive learning from [53  ###reference_b53###] by a latent space initialization strategy that enables us to allocate feature space for future unseen classes in advance, and a positional regularization term that forces the features of the different classes to consistently stay in respective latent space regions.\nThrough extensive evaluaitons on the Pascal3D [62  ###reference_b62###] and ObjectNet3D [61  ###reference_b61###] datasets, we demonstrate that our method outperforms existing continual learning techniques and furthermore surpasses them by a large margin for out-of-distribution samples. Overall, our work motivates future research on joint 3D object-centric representations.\nIn summary, the contributions of our work are:\nFor the first time, we adapt the conventional continual learning techniques of knowledge distillation and replay to the 3D neural mesh setting.\nWe propose a novel architecture, that can grow by adding new meshes for object categories over time.\nTo effectively train the features of the meshes, we introduce a strategy to partition the latent space and maintain it when new tasks are integrated.\nWe demonstrate that incremental neural mesh models can outperform 2D baselines that use existing 2D continual learning techniques by  in the in-domain and by  in the OOD setting.\nFinally, we introduce the first incremental approach for pose estimation and show that the neural mesh models outperform 2D baselines."

Attempts to close this performance gap have included data augmentation [16  ###reference_b16###] and innovative architectural designs, such as the analysis-by-synthesis approach [23  ###reference_b23###].\nAlong this line of research, recently neural mesh models emerged as a family of models[53  ###reference_b53###, 54  ###reference_b54###, 36  ###reference_b36###, 55  ###reference_b55###] that learn a 3D pose-conditioned model of neural features and predict 3D pose and object class [20  ###reference_b20###] by minimizing the reconstruction error between the actual and rendered feature maps using render-and-compare.\nSuch models have shown to be significantly more robust to occlusions and OOD data. However, they can so far only be trained on fixed datasets.\nIn this work, we present the first approach to learn them in a class-incremental setting.\nObject Pose Estimation has been approached primarily as a regression problem [51  ###reference_b51###, 40  ###reference_b40###] or through keypoint detection and reprojection [67  ###reference_b67###] in early methods. More recent research [19  ###reference_b19###, 26  ###reference_b26###] addresses object pose estimation in complex scenarios like partial occlusion. NeMo [53  ###reference_b53###] introduces render-and-compare techniques for category-level object pose estimation, showcasing enhanced robustness in OOD conditions.\nLater advancements in differentiable rendering [57  ###reference_b57###] and data augmentation [24  ###reference_b24###] for NeMo have led to further improvements in robust category-level object pose estimation, achieving state-of-the-art performance.\nHowever, these approaches are confined to specific object categories and are designed for fixed training datasets only. In contrast, our method for the first time extends them to the class-incremental setting."

To the best of our knowledge,\nour method is the first to combine a 3D inductive bias with these strategies."

For the first time, we present a model\nthat can learn new prototypical 3D representations of object categories over time. The extensive evaluation on Pascal3D and ObjectNet3D shows that our approach outperforms all baselines even in the in-domain setting and surpasses them by a large margin in the OOD case. We also introduced the first approach for class-incremental learning of pose estimation. The results overall demonstrate the fundamental advantage of 3D object-centric representations, and we hope that this will spur a new line of research in the community.\nWe gratefully acknowledge the stimulating research environment of the GRK 2853/1 \u201cNeuroexplicit Models of Language, Vision, and Action\u201d, funded by the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) under project number 471607914.\nAdam Kortylewski gratefully acknowledges support for his Emmy Noether Research Group, funded by the German Research Foundation (DFG) under Grant No. 468670075.

For the first time, we present a model\nthat can learn new prototypical 3D representations of object categories over time. The extensive evaluation on Pascal3D and ObjectNet3D shows that our approach outperforms all baselines even in the in-domain setting and surpasses them by a large margin in the OOD case. We also introduced the first approach for class-incremental learning of pose estimation. The results overall demonstrate the fundamental advantage of 3D object-centric representations, and we hope that this will spur a new line of research in the community.</span></p>\n</div>\n<div class=\"ltx_pagination ltx_role_newpage\"></div>\n<section class=\"ltx_section\" id=\"Sx1\">\n<h2 class=\"ltx_title ltx_title_section\" style=\"font-size:90%;\">Acknowledgements</h2>\n<div class=\"ltx_para\" id=\"Sx1.p1\">\n<p class=\"ltx_p\" id=\"Sx1.p1.1\"><span class=\"ltx_text\" id=\"Sx1.p1.1.1\" style=\"font-size:90%;\">We gratefully acknowledge the stimulating research environment of the GRK 2853/1 \u201cNeuroexplicit Models of Language, Vision, and Action\u201d, funded by the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) under project number 471607914.\nAdam Kortylewski gratefully acknowledges support for his Emmy Noether Research Group, funded by the German Research Foundation (DFG) under Grant No. 468670075.

+    "abstract": "In this paper, we investigate the strong convergence analysis of parareal algorithms for stochastic Maxwell equations with the damping term driven by additive noise. The proposed parareal algorithms proceed as two-level temporal parallelizable integrators with the stochastic exponential integrator as the coarse -propagator and both the exact solution integrator and the stochastic exponential integrator as the fine -propagator. It is proved that the convergence order of the proposed algorithms linearly depends on the iteration number . Numerical experiments are performed to illustrate the convergence of the parareal algorithms for different choices of the iteration number  and the damping coefficient .",

In order to model the thermal motion of electrically charged microparticles, we consider the stochastic Maxwell equations with damping term driven by additive noise as follows\nwhere  is an open, bounded and Lipschitz domain with boundary , of which  is the unit outward. Here  is the electric permittivity and  is the magnetic permeability. The damping terms  and  are usually added to simulate the attenuation of electromagnetic waves in the medium, which can be caused by absorption, scattering or other non-ideal factors in the medium. The function  and  describe electric currents (or  and  describe magnetic currents). In particular,  and  do not depend on the electromagnetic fields  and . The authors in [22  ###reference_b22###] proved the mild, strong and classical well-posedness for the Cauchy problem of stochastic Maxwell equations. Meanwhile, the authors in [20  ###reference_b20###] studied the approximate controllability of the stochastic Maxwell equations via an abstract approach and a constructive approach using a generalization of the Hilbert uniqueness method. Subsequently the work [24  ###reference_b24###] combined the study of well-posedness, homogenization and controllability of Maxwell equations with the description of the constitutive relations of complex media and dealt with deterministic and stochastic issues in both the frequency and time domains.\nSince stochastic Maxwell equations are a kind of stochastic Hamiltonian PDEs, constructing stochastic multi-symplectic numerical methods for problem (5  ###reference_###) has been paid more and more attention. The stochastic multi-symplectic numerical method for stochastic Maxwell equations driven by additive noise was proposed in [17  ###reference_b17###] based on the stochastic variational principle. Subsequently the authors in [10  ###reference_b10###] used a straightforward approach to avoid the introduction of additional variables and obtained three effecitve stochastic multi-symplectic numerical methods. Then the authors in [18  ###reference_b18###] used the wavelet collocation method in space and the stochastic symplectic method in time to construct the stochastic multi-symplectic energy-conserving method for three-dimensional stochastic Maxwell equations driven by multiplicative noise. The work in [31  ###reference_b31###] made a review on these stochastic multi-symplectic methods and summarised numerical methods for various stochastic Maxwell equations driven by additive and multiplicative noise. The general case of stochastic Hamiltonian PDEs was considered in [32  ###reference_b32###], where the multi-symplecticity of stochastic RK methods was investigated. Recently, the authors in [26  ###reference_b26###] and [27  ###reference_b27###] constructed\nmulti-symplectic DG methods for stochastic Maxwell equations driven by additive noise and multiplicative noise.\nFurthermore, the work in [16  ###reference_b16###] employed the local radial basis function collocation method and the work in [21  ###reference_b21###] utilized the global radial basis function collocation method for stochastic Maxwell equations driven by multiplicative noise to preserve multi-symplectic structure. Additionally, [4  ###reference_b4###] developed a symplectic discontinuous Galerkin full discretisation method for stochastic Maxwell equations driven by additive noise. Other efficient numerical methods for stochastic Maxwell equations also are investigated, see [30  ###reference_b30###] for the finite element method, [1  ###reference_b1###] for the numerical method based on the Wiener chaos expansion, [9  ###reference_b9###] for ergodic numerical method, [7  ###reference_b7###] for operator splitting method and [34  ###reference_b34###] for CN-FDTD and Yee-FDTD methods.\nMeanwhile, there are a lot of pregnant works focused mainly on strong convergence analysis of the numerical methods for stochastic Maxwell equations. In the temporal discretization methods, the semi-implicit Euler method was proposed in [5  ###reference_b5###] to proved mean-square convergence order is  for stochastic Maxwell equations driven by multiplicative noise. Subsequently the work in [6  ###reference_b6###] studied the stochastic Runge-Kutta method with mean-square convergence order 1 for stochastic Maxwell equations driven by additive noise. In addition, explicit exponential integrator was proposed in [11  ###reference_b11###] for stochastic Maxwell equations with mean-square convergence order  for multiplicative noise and convergence order  for additive noise. The work [4  ###reference_b4###] developed discontinuous Galerkin full discretization method for stochastic Maxwell equations driven by additive noise with mean-square convergence order  in time and  in space, where  represents  regularity. Another related work by authors of [9  ###reference_b9###] showed the ergodic discontinuous Galerkin full discretization for\nstochastic Maxwell equations with mean-square convergence order both  in\nthe temporal and spatial directions. In recent works\n[26  ###reference_b26###] and [27  ###reference_b27###], high order discontinuous Galerkin methods were designed for the stochastic Maxwell equations driven by additive noise and multiplicative noise with mean-square convergence order both . Besides, the authors of [7  ###reference_b7###] presented the operator splitting method for stochastic Maxwell equations driven by additive noise with mean-square convergence order .\nIn order to increase the convergence order and improve the computational efficiency on stochastic differential equations, the parareal algorithm has received attentions. This algorithm we focus on is a two-stage time-parallel integrator originally proposed in [23  ###reference_b23###] and further works studied on theoretical analysis and applications for differential model problems, see, for instance, [2  ###reference_b2###, 28  ###reference_b28###, 13  ###reference_b13###, 15  ###reference_b15###, 14  ###reference_b14###, 12  ###reference_b12###]. In terms of stochastic model, the work in\n[33  ###reference_b33###] investigated the parareal algorithm combining the projection method to SDEs with conserved quantities. Then the parareal algorithm for the stochastic Schr\u00f6dinger equations with weak damping term driven by additive noise was studied in [19  ###reference_b19###] with fine propagator being the exact solver and coarse propagator being the exponential -scheme. And the proposed algorithm increases the convergence order to  in the linear case for . The parareal algorithm for semilinear parabolic SPDEs behaved differently in [3  ###reference_b3###] depending on the choice of the coarse integrator. When the linear implicit Euler scheme was selected, the convergence order was limited by the regularity of the noise with the increase of iteration number, while for the stochastic exponential scheme, the convergence order always increased.\nTo the best of our knowledge, there has been no reference considering the convergence analysis of the parareal algorithm for stochastic Maxwell equations till now.\nInspired by the pioneering works, we establish strong convergence analysis of the parareal algorithms for stochastic Maxwell equations with damping term driven by additive noise. Combining the benefits of the stochastic exponential integrator, we use this integrator as the coarse -propagator and for the fine -propagator, two choices are considered: the exact solution integrator as well as the stochastic exponential integrator. Taking advantage of the contraction semigroup generated by the Maxwell operator and the damping term, we derive the uniform mean-square convergence analysis of the proposed parareal algorithms with convergence order . The key point of convergence analysis is that the\nerror between the solution computed by the parareal algorithm and the reference solution generated by the fine propagator for\nthe stochastic exponential integrator still maintains the consistent convergence results. Different from the exact solution integrator as the fine -propagator, we need to make use of the Lipschitz continuity of the residual operator rather than the integrability of the exact solution directly in this case, which requires us to make assumptions about the directional derivatives of the drift coefficient. We find that the selection of parameters have an impact on the convergence analysis results of the parareal algorithms. An appropriate damping coefficient ensures stability and accelerates the convergence results and the scale of noise induces a perturbation of the solution numerically.\nThe article is organized as follows. In the forthcoming section, we collect some preliminaries about stochastic Maxwell equations. In section 3, we devote to introducing the parareal algorithms based on the exponential scheme as the coarse -propagator and both the exact solution integrator and the stochastic exponential integrator as the fine -propagator. In section 4, two convergence results in the sense of mean-square are analyzed. In section 5, numerical experiments are dedicated to illustrate the convergence analysis with the influences on the iteration number  and the damping coefficient  and the effect of noise with different scale  on the numerical solution.\nTo lighten notations, throughout this paper, C stands for a constant which might be dependent of  but is independent of  and may vary from line to line."

Prototypes, by encapsulating essential characteristics within data, offer insights that enable tactical decision-making and enhance transparency. Traditional prototype methods often rely on sub-symbolic raw data and opaque latent spaces, reducing explainability and increasing the risk of misinterpretations. This paper presents a novel framework that utilizes semantic descriptions to define prototypes and provide clear explanations, effectively addressing the shortcomings of conventional methods. Our approach leverages concept-based descriptions to cluster data on the semantic level, ensuring that prototypes not only represent underlying properties intuitively but are also straightforward to interpret. Our method simplifies the interpretative process and effectively bridges the gap between complex data structures and human cognitive processes, thereby enhancing transparency and fostering trust. Our approach outperforms existing widely-used prototype methods in facilitating human understanding and informativeness, as validated through a user survey.",

+            "text": "In the rapidly evolving landscape of data-driven decision-making and machine learning (ML) advancements, the pursuit of explainability and interpretability stands as a critical imperative. As ML models evolve in complexity and scope, understanding their decision-making processes becomes paramount for fostering trust, ensuring accountability, and promoting fairness. Equally crucial is the comprehension of the datasets upon which these models are trained and applied. Data, often vast and heterogeneous, serve as the foundational bedrock upon which ML models operate. However, the sheer volume and intricacy of data present formidable challenges in discerning meaningful insights, uncovering hidden biases, and ensuring the quality and fairness of AI-driven systems. Thus, the need for transparent and interpretable methodologies that not only shed light on ML model behavior but also facilitate a deeper understanding and management of data is unequivocal.\nPrototypes have emerged as pivotal constructs not only for explaining machine learning models but also for comprehending the underlying data (Kim et al., 2016  ###reference_b19###). Acting as archetypal representations, prototypes encapsulate the essential characteristics or features of specific clusters or classes within a dataset, providing intuitive insights into its inherent properties. Research on human cognition and reasoning has shown that the use of prototypical examples is fundamental to the development of effective strategies for tactical decision-making (Newell et al., 1972  ###reference_b31###; Cohen et al., 1996  ###reference_b8###), and recent user studies show that concept-based and prototype explanations are prefered by users over other existing explanations (Kim et al., 2023  ###reference_b20###).\nFor instance, in information retrieval, prototypes act as exemplars for enhancing search efficiency and relevance ranking by aiding in query expansion. Additionally, there is a growing interest within the AI community in case-based reasoning and prototype-based classifiers, highlighting the versatility and acceptance of prototypes in various applications. By leveraging prototypes, stakeholders can navigate the complexities of data-driven decision-making more effectively, fostering transparency and enabling nuanced decision-making processes.\n###figure_1### A sample image from class 2 of the CLEVR-Hans3 dataset, depicting a big blue rubber cylinder, a small purple rubber cylinder, a small cyan metal cylinder, a small red rubber sphere, and a small purple metal cube.\nHowever, the majority of existing prototype approaches exhibit a major structural limitation that undermines their effectiveness and trustworthiness: they rely solely on the raw, unstructured feature space. This can be problematic from many aspects. Firstly, the feature space is often not understandable, an issue that persists across many eXplainable AI (XAI) methods, and can result in lack of intuition and potential for misinformation (Rudin, 2019  ###reference_b34###; Mittelstadt et al., 2019  ###reference_b27###; Mastromichalakis et al., 2024  ###reference_b25###; Liartis et al., 2023  ###reference_b24###; Miller, 2019  ###reference_b26###). For example consider genomics, where the feature space consists of DNA sequences which can consist of millions or billions of base pairs for an organism, and in which there can be interdependencies that are thousands of base pairs apart. Parts of the genome might be irrelevant, others might regulate the expression of genes that are elsewhere in the sequence, others might be genes themselves etc. This raw feature representation is not understandable, even to a domain expert, so a traditional prototype in this case would not be helpful.\nSecondly, in many models, especially those involving complex interactions or relationships between features, a single or even a few examples might not capture the full range of interactions or the subtleties involved in model decisions. This can make it difficult to convey the full complexity of the model\u2019s decision-making process through just prototypical examples, and can lead to oversimplification and misinterpretation. For example, consider the image shown in Figure 2  ###reference_### from the CLEVR-Hans3 dataset (Stammer et al., 2021  ###reference_b37###), for which it is known that the class semantics are \u201csmall metal cube and small sphere\u201d. By just looking at the pixel representation of the prototype, even if the prototypical parts of the image have been highlighted (see bounding boxes in Figure 2  ###reference_###), it is impossible to discern the characteristics that make them prototypical. It could be the color, size, shape or texture of each object, or even their location in the image. Therefore, without telling a user the specific semantics that make this image (and the highlighted parts) prototypical, it is easy for them to misinterpret the explanation and be misled.\nThirdly, prototypes cannot be expected to generalize to all cases, and even though they might be excellent representations of a particular class, it is not made clear to an end-user which aspects of the prototype make it representative, and to which cases it might generalize.\nAdditionally, several prototype methods do not act on the feature representation itself, opting instead to utilize black-box models that transform the features into a lower-dimensional latent space representation\n. This exacerbates the aforementioned issues, as latent representations are non-intuitive and unintelligible to humans (Wan et al., 2024  ###reference_b41###), and it also creates a paradoxical situation where non-interpretable models are used to provide explanations or interpretability, which might also facilitate malicious manipulations (Hoffmann et al., 2021  ###reference_b18###). Instead, recent research emphasizes the importance of explaining the prototypes (Nauta et al., 2021a  ###reference_b28###; Wan et al., 2024  ###reference_b41###) underscoring the necessity for a semantic level of information alongside prototypes.\nOur approach represents a novel solution to address the limitations in existing prototype methods. To tackle the challenge of using raw data to define prototypes, we propose a shift towards semantic prototypes. In our approach, prototypes are not selected based on raw input features but on the semantic descriptions associated with each data point. By leveraging concept-based semantic descriptions to create clusters of data described by semantic rules as shown in Figure 1  ###reference_###, we ensure that prototypes are representative of the underlying data distribution while maintaining transparency and interpretability. This process eliminates the need to map data to a non-interpretable latent space, as distances are measured on the more intuitive semantic level. Moreover, our method dynamically determines the number of prototypes needed to semantically cover the entire data distribution, enhancing its adaptability and effectiveness. Furthermore, our approach mitigates the issue of providing explanations solely in terms of raw sub-symbolic data by providing both prototypical examples and the corresponding prototypical semantic description. Each cluster\u2019s semantic description serves as the prototypical part of the data point on the semantic level, offering insights into why a particular example is deemed a prototype. This combination of prototypical examples and semantic descriptions bridges the gap between the semantic and data levels, enhancing the interpretability and trustworthiness of our method. By enabling users to question and scrutinize each step of the process on the semantic level, we foster warranted trust and confidence in the explanations provided. Thus, our approach offers a simple yet effective and intuitive solution to enhance the interpretability of prototype-based explanations, mitigating the drawbacks of existing approaches."

+            "text": "Our work is positioned at the intersection of several key areas within artificial intelligence, notably explainable AI (XAI), prototype-based methods, and case-based reasoning (Aamodt and Plaza, 1994  ###reference_b2###). By leveraging semantic prototypes, our approach not only enhances model interpretability but also facilitates a clearer understanding of datasets, offering a comprehensive overview of their inherent structure and characteristics.\nClassical algorithms like k-medoids (Rousseeuw and Kaufman, 1987  ###reference_b33###) have traditionally been used to select representative subsets of data points, illustrating early methods of data summarization through clustering. More recently, seminal works such as (Kim et al., 2016  ###reference_b19###) and (Gurumoorthy et al., 2019  ###reference_b16###) have leveraged prototypes to critically evaluate models and enhance transparency in machine learning decisions, establishing prototypes as an interpretability method.\nA significant body of research has focused on using prototypes to create more interpretable classifiers. This approach, often referred to as case-based or example-based classification, aims to enhance the transparency of AI models by relying on representative examples. By integrating prototypes into the classification process, these methods strive to provide intuitive, example-driven explanations that make the model\u2019s decisions more understandable to humans. (Chen et al., 2019  ###reference_b6###) is a seminal work in this direction, introducing ProtoPNet, a deep network architecture that dissects images by finding prototypical parts and combines evidence from these prototypes to make final classifications. (Wang et al., 2023  ###reference_b42###) claims to improve the classification performance of ProtoPNet with a method to learn support prototypes that lie near the classification boundary in the feature space. In a similar vein, (Nauta et al., 2021b  ###reference_b30###) introduces ProtoTree, a prototype-based decision tree that employs prototypical patches as proxies for class-defining semantics.\nSeveral other works follow this rationale of prototypical learning through various approaches (Angelov and Soares, 2020  ###reference_b3###; Arik and Pfister, 2020  ###reference_b4###; Xue et al., 2022  ###reference_b45###; Li et al., 2018  ###reference_b22###; Rymarczyk et al., 2021  ###reference_b36###, 2022  ###reference_b35###; Wang et al., 2023  ###reference_b42###). However, their reliance on raw data limits the interpretability of their methods and the intuitiveness of the prototypes, potentially leading to misleading explanations.\nRecent research aligns with our work by acknowledging the limitations of providing explanations in terms of raw data and highlights the necessity to \u201cexplain the prototypes\u201d. In (Nauta et al., 2021a  ###reference_b28###), the authors introduce a method to provide further insights for prototypes based on existing methods like ProtoPNet by altering some characteristics of the image, such as hue and saturation, and providing explanations based on that information. Similarly, (Wan et al., 2024  ###reference_b41###) proposes the Semantic Prototype Analysis Network (SPANet), an interpretable object recognition approach that through additional semantic information enables models to explicate the decision process by \u201cpointing out where to focus\u201d and \u201cexplaining why\u201d on a semantic level. Our work also utilizes information on the semantic level to define prototypes and produce semantically enriched explanations, bearing strong similarities with recent rule-based (Mastromichalakis et al., 2024  ###reference_b25###; Liartis et al., 2023  ###reference_b24###, 2021  ###reference_b23###) and counterfactual methods (Dervakos et al., 2023  ###reference_b9###) that use semantic descriptions of data to provide intuitive, human-understandable explanations.\nOur work is further supported by research discussing the shortcomings of latent space prototype interpretability, as outlined in (Hoffmann et al., 2021  ###reference_b18###), where the non-interpretability of latent space is highlighted, showing that existing methods using non-interpretable embedding spaces limit the interpretability of prototypes and are vulnerable to malicious attacks. Efforts to bridge the \u201csemantic gap\u201d between latent space and pixel space through the correlation of prototypes with ground-truth object parts (Nauta et al., 2023  ###reference_b29###) still rely on opaque procedures to map raw data to the latent space. (Wang et al., 2021  ###reference_b43###) claims to address this opacity by introducing a plug-in transparent embedding space to bridge high-level input patches and output categories.\nIn contrast, our approach eliminates the reliance on non interpretable latent spaces by using semantic descriptions directly, making each step transparent and interpretable. This not only enhances trust in the explanations provided but also allows for a more robust understanding of both the model and the data. Our method stands out by addressing both the need for clear, semantic-level explanations and the requirement for prototypes that truly represent the data in an intuitive and human-understandable way."

+            "text": "In this section we define the proposed framework for semantic prototypes. At the core of the framework is the notion of an Attribute Set Description (ASD), which provides a simple way to represent data samples semantically, as a set of entities, where an entity is represented as a set of attributes.\nGiven a set , an Attribute Set Description is a set of the form  where each  is of the form .\nThe set  is a vocabulary that lists all the possible attributes an entity can have, so an ASD lists the attributes of a collection of entities. For defining semantic prototypes, we assume that we have data where samples are described by an ASD.\nSpecifically, we assume that our data  consist of triples  where  is a raw data point, (e.g. an image, audio signal, DNA sequence etc.)  is a label, and  an semantic description of that data point. We assume that  is an ASD that reflects the contents of .\nIn the case of an image the entities could be objects depicted within the image, each characterised by shape, colour, size, etc., while in the case of a speech signal, the entities could be utterances that are characterized by loudness, pitch, intonation, rhythm etc.\nThe assumptions that i) there are available data with ASDs and ii) that the ASDs accurately describe the data samples are worth further discussion. In the ideal case, such semantic descriptions will have resulted by human expert annotation, especially in decision-critical domains. There already exist multiple datasets with manually-added semantic descriptions or metadata that can be used as ASDs, both for general-purpose and domain-specific tasks, such as Audio set (Gemmeke et al., 2017  ###reference_b15###) including audio events accompanied by an ontology describing their semantics, the Visual Genome (Krishna et al., 2017  ###reference_b21###), containing images accompanied by scene graphs, where entities are linked semantically to WordNet (Fellbaum, 2010  ###reference_b13###), and the cancer genome atlas (Weinstein et al., 2013  ###reference_b44###), that includes genomic sequences along with a rich set of clinical and other information, among others. Furthermore, one could also use traditional, transparent feature extraction techniques to generate the ASDs, or, even more complex models, such as large vision-language models, similar to recent works that relate to ours (Wan et al., 2024  ###reference_b41###). The point of the ASD is to provide a meaningful description of a data sample at a level of abstraction that is understandable.\nAn ASD can also be used to describe a set of data samples. Given an ASD , we will say that  subsumes  if . This can be thought of as  being more general than . Given a data point , if  subsumes  we will also say that  describes the data point . Essentially,  describes , if the description  of  contains entities with attributes that match or exceed those described in , thus, there can be ASDs that describe multiple data points. For example a data sample with ASD  is described by the ASD  , and so is the data sample with ASD . We utilize this idea for the semantic prototypes, by first finding ASDs which describe only data points with a particular label. We call such ASDs class cluster descriptions (CCD) of that label.\nA class cluster description of class , is an ASD  such that, if  describes a datapoint  (i.e.  subsumes ), then .\nIntuitively, a CCD semantically describes a cluster of data points that belong to a specific class, and no other data points. It can be interpreted as an IF THEN rule in that IF a data point is described by a CCD, then it belongs to that particular class. The purpose of identifying and semantically describing clusters of data points is to subsequently find the most representative or informative samples for those clusters, which can then be given as prototypes, along with their semantic description (ASD), and the semantic description of why they belong to their class (CCD). In particular, given a CCD for a label, the corresponding semantic prototype is the data point whose ASD contains the least redundant information among points that fit that description.\nA semantic prototype  for a class cluster description  is a data point  that is described by , and for which, given a distance metric , for every other data point  that is described by , it holds that .\nIntuitively, this means that a semantic prototype is a data point that materialises all the semantic information of the class description, since it is described by it, and contains as little extra information as possible.\nThe choice to limit the extra information is made to ensure that end-users are not distracted by irrelevant characteristics of the data point, such as objects in an image that do not affect what class it belongs to. Regarding the distance metric , in our implementation we opt for a set edit distance, as it has been used in other semantic explainability methods (Dervakos et al., 2023  ###reference_b9###), but other distance metrics could potentially be used, such as the extension of Jaccard similarity to sets of sets."

+            "text": "As the space of all possible CCDs is exponentially large, our approach works by first heuristically generating a large (but polynomial) number of potential CCDs, filtering out those that do not satisfy the criteria (i.e. the clusters contain data samples that have a different label), and finally choosing a subset of the computed CCDs, depending on the number of prototypes that we want to produce and on the class coverage of the CCDs.\nGiven a dataset , and a class  for which we want to produce prototypical examples, we would ideally like to produce the smallest number of CCDs that describe the entirety of class  without describing any data points from other classes. It is worth mentioning that since finding CCDs is equivalent to finding rules of the form \u201cIF data sample contains entities with specific attributes THEN it is classified to class \u201d, existing rule-based methods could be adapted for finding CCDs (Zhou et al., 2003  ###reference_b46###; Augasta and Kathirvalavakumar, 2012  ###reference_b5###; Mastromichalakis et al., 2024  ###reference_b25###; Liartis et al., 2021  ###reference_b23###).\nIn our implementation, we utilise Algorithm 1  ###reference_### to compute the initial CCDs, using  as the positive data points and  as the set of negative data points. Alg. 1  ###reference_### is a greedy algorithm inspired by (Liartis et al., 2021  ###reference_b23###) that starts with an ASD, and using a similarity metric (eq. 1  ###reference_###) as a heuristic, greedily merges (Alg. 2  ###reference_###) positive descriptions into more general ones, and subsequently checks that the more general descriptions do not describe any negative data points. In contrast to (Liartis et al., 2021  ###reference_b23###), we repeat this process for each positive data point, because we want to ensure that each positive data point fits at least one CCD, and to also mitigate \u201dbad\u201d choices induced by the heuristic. This strikes a balance between only utilizing each data point once, and exploring the combinatorially large number of all possible choices.\nThe similarity metric we use, as described in equation 1  ###reference_###, utilizes the Jaccard similarity to compare the entities described in each ASD. For each entity in , it calculates the maximum number of attributes it shares with any entity in . This is averaged over the entities in , repeated symmetrically for the entities in , and then these two quantities are averaged. We average over entities so that if  describes many more entities than , it does not dominate the total similarity and vice versa. The two quantities are averaged so that the final quantity is between 0 and 1, as is commonly required of a similarity metric.\nThe merge operation also follows the paradigm of (Liartis et al., 2023  ###reference_b24###), by finding all common attributes for pairs of entities from  and , and then trims the resulting ASD. This way of combining  and  is essentially the direct product of finite structures, applied to ASDs. It is also the join operation on the lattice induced by ASD subsumption. The resulting ASD of this merge operation holds the property that it subsumes  and , and is subsumed by any other ASD that subsumes both  and . Therefore, it is their most specific generalization. This operation is widely adopted for separating structured positive and negative examples (Liartis et al., 2023  ###reference_b24###; Cima et al., 2022  ###reference_b7###; Ortiz, 2019  ###reference_b32###; Guti\u00e9rrez-Basulto et al., 2018  ###reference_b17###). The trimming operation used only removes redundant entity descriptions, without sacrificing the property of the most specific generalization.\nAlg.1 results in a large set of CCDs which are used as candidates for subsequently finding semantic prototypes. As each CCD results in a prototype, we want to limit their number so that they can all be shown to a user without overwhelming them. In our implementation we again do this greedily, by choosing at each step the CCD that describes the most positive samples that are not already described by any previously selected class descriptions. Selecting the fewest number of CCDs that in total describe all positive data points is an instance of the set cover problem, while selecting  CCDs that describe as many positive data points as possible is an instance of the maximum coverage problem. Both problems are NP-complete and the greedy algorithm is the best polynomial-time approximation, up to lower-order terms, unless P=NP (Vazirani, 2001  ###reference_b39###; Feige, 1998  ###reference_b12###; Dinur and Steurer, 2014  ###reference_b11###)."

In our implementation, the closeness is determined through the set edit distance, a metric quantifying the distance between the CCD and the ASD of each data point. In particular, as we know that the CCD  describes the data sample , the only necessary edits to transform  into  are insertions of attributes into the sets contained in . To do this, for every pair of sets  where ,  and  we compute the number of insertions . Then the pairs  are organized into a bipartite graph, where the weights of the edges are set to be the number of insertions computed previously.

Finally, we compute the minimum number of additions required to transform  to , yielding the edit distance between the class description and the data point, by adapting the minimum weight full match algorithm, as used in (Filandrianos et al., 2022  ###reference_b14###). This is computed for all data points, and then the semantic prototype is chosen to be the one with the least edit distance."

For example, all images in Class 1 contain at least one large cube and one large cylinder; Class 2 images feature at least one small metal cube and one small sphere; Class 3 images include at least one large blue sphere and one small yellow sphere.\nThe following Class Characteristic Descriptions (CCDs) produced by our method correctly reflect the characteristics of each class\nFigure 3  ###reference_### shows the prototypical images for each class in the training set of CLEVR-Hans3, generated by Protodash (Gurumoorthy et al., 2019  ###reference_b16###) and our proposed approach.

This challenge is even more pronounced with prototypes produced by methods like Protodash, where the amount of encapsulated information can be overwhelming.

The purpose of this survey is to evaluate the effectiveness of prototype methods in teaching individuals about an unfamiliar task, through two primary stages: training and testing. During the training phase, participants are exposed to prototype instances from two analogous classes within a specified method, accompanied by relevant explanations where applicable. For example, Protodash employs solely images, ProtoPNet features images with a bounding box, and our method presents images alongside textual CCD. Each participant reviews four prototypes per class, totaling eight prototypes. To mitigate bias from recognizable class names, such as \u201cYellow-breasted Chat\u201d, these names are replaced with \u201cClass A\u201d and \u201cClass B\u201d.\nIn the testing phase, participants are required to classify ten images from the test set as either \u201cClass A\u201d or \u201cClass B.\u201d This approach is designed to assess their ability to learn the task by simply viewing random images from the training set, without any systematic selection algorithm or additional explanations. To evaluate the generalizability of the method, the experiment employs different pairings of labels as \u201cClass A\u201d and \u201cClass B\u201d. These pairs, such as Least Auklet versus Parakeet Auklet and Pelagic Cormorant versus Brandt Cormorant were selected because of their high visual similarity, which was confirmed by their high confusion rates as identified by the pretrained classifier cited in (Vandenhende et al., 2022  ###reference_b38###).\nParticipants underwent these two phases for the following six different methodologies: only CCDs, Random Images (baseline), semantic prototypes (our method), ProtoPNet (Chen et al., 2019  ###reference_b6###), Protodash (Gurumoorthy et al., 2019  ###reference_b16###), and ProtoPNet* (ProtoPNet prototypes along with explanations produced using the methodology introduced in (Nauta et al., 2021a  ###reference_b28###)). The CCDs were presented before the random images to ensure that participants had no prior knowledge about the distribution of the images, starting with only textual descriptions provided by the CCDs. These were used as a baseline for our method to evaluate the usefulness of the prototypes compared to plain semantic descriptions. Different classes of birds were randomly permutated among the different methods so that each user couldn\u2019t use prior knowledge from a previous step of the survey to classify the images of a later method. Participants were ultimately asked to indicate which prototype method they preferred and found most helpful.\nThe study involved 20 PhD candidates in computer science who participated voluntarily after a call for participation. Altogether, they conducted 120 tests in total. The candidates possessed no prior knowledge about bird species, which ensured an unbiased approach to the tasks presented.\nTable 1  ###reference_### presents the results, showcasing the accuracy and participant preferences for each method.\nThe results of the user survey clearly demonstrate that our method of Semantic Prototypes (ProtoSem) outperformed all other methods in terms of performance in machine teaching and user satisfaction, exhibiting the highest accuracy and the lowest standard deviation along with the highest user preference. This indicates that our approach effectively helped users focus their attention in the right direction, achieving a consistent understanding across participants.\nWe see a significant discrepancy between the accuracy of participants who only read the CCDs of the two classes and those who viewed actual images from the dataset. While CCDs provide essential information for differentiating each class, they alone are insufficient for users to fully grasp the necessary distinctions. Familiarity with dataset instances plays a crucial role in properly understanding how to differentiate the classes. Additionally, the high standard deviation in performance suggests that the criteria for class selection vary significantly among users. Initially, this variation might seem counter-intuitive since users are provided with the fundamental characteristics of the classes, seemingly simplifying the classification task. However, participants struggled to intuitively grasp these explanations without examples from the dataset, as interpretations of a rule such as \u201cThe bird has a plain pattern on its head\u201d varied widely among users who had not seen how this characteristic manifests in actual birds.\nMoreover, although adding supplementary information to each prototype intuitively appears beneficial, this is not reflected in user performance. The accuracy of users who learned with the help of explanations from ProtoPNet and ProtoPNet*, which include images along with two different types of additional information, was comparable to that of learning from randomly selected images without any explanations. Notably, ProtoPNet\u2019s performance was slightly below this baseline, with a relatively higher standard deviation, indicating that the criteria for classifying images varied considerably. ProtoPNet* showed slightly improved performance and a relatively lower standard deviation, but still very close to the baseline.\nAdditionally, Protodash, which presents less information compared to other methods (except for the baseline), achieved higher performance than the preceding methods. This improvement primarily occurred because users could intuitively discern the differences between the two classes by comparing Protodash prototypes. Additionally, Protodash, which presents less information compared to other methods (except for the baseline), achieved higher performance than the preceding methods. This improvement primarily occurred because users could intuitively discern the differences between the two classes by comparing Protodash prototypes.\nAfter each participant completed the user survey, we conducted short interviews to gather feedback and insights on the methods. Here we present some notable observations highlighted by multiple participants.\nFirst, participants found it difficult to map the semantic information of the CCDs to the actual data when the prototypical images were not present. This underscores the importance of providing enhanced explanations in multiple formats, especially in areas where users lack expertise. Additionally, participants criticized the seemingly incorrect patches of ProtoPNet, noting that they often ignored these patches and instead identified their own patterns in the images. Many participants found the semantic explanations of ProtoPNet* unintuitive and uninterpretable because they could not relate them to the data, often choosing to disregard them.\nRegarding our method, some users mentioned that the presence of the semantic description helped them identify the distinguishing characteristics of the classes, though they had to pay more attention to process all the provided information compared to methods offering only plain images. They also suggested that smaller, more focused rules would be greatly beneficial.\nRegarding user preferences, it is important to note that half of the participants found our method\u2019s explanations more helpful than any of the alternatives. However, Table 1  ###reference_### also reveals a preference for methods that offer minimal information, specifically those consisting only of images without any textual content. This is highlighted by the fact that 45% of users identified the prototypes provided randomly, by ProtoPNet, and by Protodash as the most helpful. Interestingly, there was a stronger preference for a set of randomly selected images over the ProtoPNet* prototypes, which include images accompanied by textual explanations, even though the latter method resulted in higher user performance. Additionally, users seemed to prefer the ProtoPNet explanation, which features an image with a bounding box, despite its lower effectiveness for learning.\nThis highlights an important trade-off in explanation methods: informativeness versus simplicity. Some users prefer methods that contain the most useful information and can help them perform a task with careful attention, while others prefer explanations that are simple and do not require thorough investigation, even if they lead to poorer results. Therefore, it is important to keep our methods as concise as possible, avoiding unnecessary information to create explanations that are both simple and informative."

+            "text": "In this work, we have introduced a framework for producing semantic prototypes, given a dataset that is enriched with human-understandable semantic information. We have developed a methodology for computing such semantic prototypes in practice, and we have demonstrated their merits qualitatively and quantitatively. The two main takeaways from our work are that i) It is important that prototypes are accompanied by some form of explanation of \u201cwhy is this a prototype?\u201d, which should be transparent and reliable, and ii) It is useful to compute prototypes in terms of their semantics, instead of their feature representation, and to make sure that there is as little as possible redundant information. This ensures that a user can more easily extrapolate the semantics of a class, or a cluster, compared to choosing the most representative sample in the dataset which might contain redundancies. Especially in large complex datasets, it could be challenging to find data which contains only information that causally links it to a class and as least additional information as possible, thus relying on the distribution of features could lead to less understandable prototypes, compared to relying on the semantic information.\nRegarding future extensions of our work, we have identified several key areas to be explored. Firstly, as Large Language Models (LLMs) are prevalent in both academia and industry, an interesting area to explore is the utilization of prototypes and their descriptions as a complement or enhancement to few-shot or in-context learning. Furthermore, for several natural language processing tasks, it might be useful to utilize LLMs for generating semantic descriptions, and then employing our proposed method for finding semantic prototypes in the data. A second interesting area to explore is the utilization of knowledge representation and knowledge graphs. In particular, the scale and interconnectedness of such structured data can be very useful for identifying clusters and prototypes semantically. In this regard, an extension of the algorithmic approach from sets of sets representations to labeled directed graph representations will provide much more expressive descriptions, which might in turn result in more understandable and informative prototypes.\nThirdly, there is an array of domain-specific applications for the proposed methodology. An example is the domain of music, where symbolic representations, such as musical scores and notation can serve as semantic descriptions of audio recordings. Furthermore, besides prototypes, there are numerous other forms of explanations that could potentially benefit from utilizing the human-understandable semantic level of abstraction and could be combined with prototypes, similar to how we combine the prototypes with CCDs which are closely related to rule-based explanations. An example would be accompanying the prototypes with their counterfactual data point, along with the associated semantic descriptions. Finally, the difficulty of objectively evaluating XAI methodologies and frameworks, and reproducing results is a known issue. In the future, we plan to extend the evaluation procedure to more participants of different backgrounds, and ideally guided by disciplines of human behavior and cognition, it would be worth exploring further what a good explanation should look like."

+    "abstract": "Recent advancements in 3D object detection have benefited from multi-modal information from the multi-view cameras and LiDAR sensors.\nHowever, the inherent disparities between the modalities pose substantial challenges.\nWe observe that existing multi-modal 3D object detection methods heavily rely on the LiDAR sensor, treating the camera as an auxiliary modality for augmenting semantic details.\nThis often leads to not only underutilization of camera data but also significant performance degradation in scenarios where LiDAR data is unavailable.\nAdditionally, existing fusion methods overlook the detrimental impact of sensor noise induced by environmental changes, on detection performance.\nIn this paper, we propose MEFormer to address the LiDAR over-reliance problem by harnessing critical information for 3D object detection from every available modality while concurrently safeguarding against corrupted signals during the fusion process.\nSpecifically, we introduce Modality Agnostic Decoding (MOAD) that extracts geometric and semantic features with a shared transformer decoder regardless of input modalities and provides promising improvement with a single modality as well as multi-modality.\nAdditionally, our Proximity-based Modality Ensemble (PME) module adaptively utilizes the strengths of each modality depending on the environment while mitigating the effects of a noisy sensor.\nOur MEFormer achieves state-of-the-art performance of 73.9% NDS and 71.5% mAP in the nuScenes validation set.\nExtensive analyses validate that our MEFormer improves robustness against challenging conditions such as sensor malfunctions or environmental changes.\nThe source code is available at https://github.com/hanchaa/MEFormer",

[42  ###reference_b42###], previous frameworks [1  ###reference_b1###, 28  ###reference_b28###, 10  ###reference_b10###, 27  ###reference_b27###] have LiDAR reliance problem that primarily relies on LiDAR modality and treats camera modality as an extra modality for improving semantic information, even though recent studies [14  ###reference_b14###, 11  ###reference_b11###, 12  ###reference_b12###] show that the geometric information can also be extracted solely from camera modality.\nThe LiDAR reliance problem makes the framework fail to extract geometric information from camera modality, which results in missing objects that can only be found by the camera e.g., distant objects.\nThis problem is exacerbated when the LiDAR sensor is malfunctioning.\nIn LiDAR missing scenarios during inference, although the model is trained with both modalities, it shows inferior performance to the same architecture trained only with camera modality or even completely fails to perform the detection task (see the left graph of Fig. 1  ###reference_###).\nMoreover, previous works [16  ###reference_b16###, 13  ###reference_b13###] simply fuse the point feature and image pixel feature in the same coordinate in Bird\u2019s-Eyes-View (BEV) space without considering the disparities between two modalities.\nIn a challenging environment where one modality exhibits weak signals, such as at night time, prior works may suffer from a negative fusion that the defective information from a noisy modality adversely affects the correct information obtained from another modality, which results in corrupted detection performance as shown in the right side of Fig. 1  ###reference_###.\n###figure_1### In this paper, we introduce the Modality Ensemble transFormer, dubbed MEFormer, which effectively leverages the inherent characteristics of both LiDAR and camera modalities to tackle the LiDAR reliance and negative fusion problems.\nFirst, inspired by multi-task learning [20  ###reference_b20###, 44  ###reference_b44###], we propose the Modality-Agnostic Decoding (MOAD) training strategy to enhance the ability of the transformer decoder in extracting both geometric and semantic information regardless of input modalities.\nIn addition to the multi-modal decoding branch, which takes both modalities as input, we introduce auxiliary tasks, where the transformer decoder finds objects with single-modal decoding branches that take only a single modality as input.\nThis alleviates the LiDAR reliance problem by enabling the decoder to extract the information needed for 3D object detection from individual modalities.\nIn addition, we propose Proximity-based Modality Ensemble (PME), which alleviates the negative fusion problem.\nA simple cross-attention mechanism with our proposed attention bias generates a final box prediction by integrating the box candidates from all modality decoding branches.\nPME adaptively aggregates the box features from each modality decoding branch depending on the environment and mitigates the noise that may occur in the multi-modal decoding branch.\nExtensive experiments demonstrate that MEFormer exhibits superior performance.\nEspecially in challenging environments such as sensor malfunction, MEFormer shows robust performance compared to previous works.\nOur contributions are summarized as:\nWe propose a novel training strategy Modality-agnostic Decoding (MOAD), which is effective in addressing the LiDAR reliance problem by better utilizing information from all modalities.\nWe introduce the Proximity-based Modality Ensemble (PME) module, which adaptively aggregates box predictions from three decoding branches of MOAD to prevent the negative fusion problem.\nMEFormer achieves the state-of-the-art 3D object detection performance on nuScenes dataset.

In particular, PETR [14  ###reference_b14###] showed efficacy in encoding 3D coordinates into image features through positional encoding, implicitly deducing 3D-2D correspondences and achieving good performance.\nHowever, relying solely on a camera sensor for 3D perception, while advantageous due to its lower cost than a LiDAR sensor, faces limitations stemming from the inherent ambiguity in predicting 3D features from the 2D image.\nMulti-modal 3D Object Detection.\nIn the domain of 3D object detection for autonomous driving, multi-modal detection methods that leverage data from both LiDAR sensors and multi-view cameras achieve state-of-the-art performance.\nThese two sensors provide complementary information to each other, prompting numerous studies [22  ###reference_b22###, 41  ###reference_b41###, 27  ###reference_b27###, 28  ###reference_b28###, 9  ###reference_b9###, 3  ###reference_b3###, 4  ###reference_b4###] to explore methodologies for learning through these both modality.\nTransFusion [1  ###reference_b1###] and DeepFusion [10  ###reference_b10###] introduce a transformer-based method that utilizes LiADR features as queries, and image features as keys and values.\nMeanwhile, BEVFusion [16  ###reference_b16###, 13  ###reference_b13###] shows commendable performance by lifting 2D features into a unified Bird\u2019s Eye View (BEV) space following LSS [21  ###reference_b21###], and subsequently applying a 3D detector head.\nDeepInteraction [39  ###reference_b39###] applies iterative cross-attention by extracting queries from each modality to fully exploit modality-specific information.\nSparseFusion [35  ###reference_b35###] learns sparse candidates acquired via modality-specific detectors and fuses these sparse candidates to generate the final outputs.\nCMT [36  ###reference_b36###] aggregates information into a query with the assistance of modality positional embedding to generate final boxes. However, most previous studies are highly dependent on LiDAR modality, not fully exploiting the information inherent in each modality.\nFurthermore, the modality fusion methods often overlook the distinctions between modalities, leading to a degradation of robustness in scenarios where a specific sensor introduces noise.\nRobust Multi-Modality Fusion.\nIn real-world driving scenarios, sensor failures are prevalent and adversely affect the stability required for autonomous driving [34  ###reference_b34###, 6  ###reference_b6###, 43  ###reference_b43###, 42  ###reference_b42###, 25  ###reference_b25###, 47  ###reference_b47###].\nApart from a simple sensor missing, external environment noise or sensor malfunctions can severely impair robust 3D perception.\nWhile many studies [1  ###reference_b1###, 16  ###reference_b16###, 13  ###reference_b13###, 10  ###reference_b10###, 39  ###reference_b39###, 35  ###reference_b35###] have explored robust 3D detection through multi-sensor fusion, they primarily focus on achieving superior performance on complete multi-modal inputs.\nHowever, reliance on an ideal sensor results in significant performance degradation when a specific sensor malfunctions, diminishing the effectiveness of the fusion approach compared to utilizing a single modality.\nSpecifically, existing fusion methods heavily rely on LiDAR modality, and the camera is used in an auxiliary role, resulting in inferior performance in the case of LiDAR corruption [42  ###reference_b42###].\nIn this paper, we propose a framework that reduces reliance on specific modalities, mitigates the negative fusion problem, and achieves robust detection performance even in scenarios involving noise or sensor missing."

+    "abstract": "WalledEval is a comprehensive AI safety testing toolkit designed to evaluate large language models (LLMs). It accommodates a diverse range of models, including both open-weight and API-based ones, and features over 35 safety benchmarks covering areas such as multilingual safety, exaggerated safety, and prompt injections. The framework supports both LLM and judge benchmarking and incorporates custom mutators to test safety against various text-style mutations, such as future tense and paraphrasing. Additionally, WalledEval introduces WalledGuard, a new, small, and performant content moderation tool, and two datasets: SGXSTest and HIXSTest, which serve as benchmarks for assessing the exaggerated safety of LLMs and judges in cultural contexts. We make WalledEval publicly available at https://github.com/walledai/walledeval.",

Alongside these closed variants, there has been a surge in open-weight models, including the popular series of Mistrals Jiang et al. (2023  ###reference_b15###), Llamas Dubey et al. (2024  ###reference_b12###) and Gemmas Team et al. (2024  ###reference_b21###).\nAs new models continue to emerge with enhanced knowledge and multitasking capabilities, it is crucial to assess their safety risks comprehensively. Potential harms include training data leakage, biases in responses and decision-making (potentially leading to bias laundering), and unauthorized use, for example, for purposes such as terrorism and the generation of sexually explicit content Vidgen et al. (2024  ###reference_b23###). This increases the need for a one-stop center for safety evaluations of advanced AI systems; we thus introduce a Python-based framework WalledEval.\n###figure_1### The following are features of WalledEval:\nOpen-weight and API-based model support. WalledEval supports a wide array of open-weight models built on the HuggingFace Transformers library Wolf et al. (2019  ###reference_b24###), allowing users to test Llamas, Mistrals and Gemmas, amongst others. It also supports API inference endpoints from proprietary and open-weight model hosts, including OpenAI, Anthropic, Google, Groq, and Together, and is continually enhancing support for additional hosts.\nComprehensive safety benchmarks. WalledEval hosts over 35 AI safety benchmarks 111Datasets are available at https://hf.co/walledai  ###reference_hf.co/walledai###., allowing users to perform comprehensive safety tests on LLMs across dimensions such as multilingual safety (e.g., the Aya Red-Teaming dataset, Ahmadian et al. (2024  ###reference_b3###)), exaggerated safety (e.g., XSTest, R\u00f6ttger et al. (2023  ###reference_b20###)), and prompt injections (e.g., WildJailbreak).\nJudge support. WalledEval also supports various safety judges, including content moderators (guardrails) such as LlamaGuard and LionGuard. As part of this work, we also release a new content moderator, WalledGuard222https://hf.co/walledai/walledguard-c  ###reference_###., which is approximately 16 times smaller than state-of-the-art guardrails like LlamaGuard 3 and its previous versions. WalledGuard outperforms existing guardrails on the Aya Red-Teaming (English) dataset while maintaining performance within a 3% drop compared to LlamaGuard 2 (the top-performing in table 3  ###reference_###) on XSTest. We also release a new benchmark SGXSTest333https://hf.co/datasets/walledai/SGXSTest  ###reference_###., a manually curated set of prompts to access exaggerated safety (refusals) in the cultural context of Singapore, which is considered a representative example of Southeast Asian diversity.\nBeyond this, WalledEval supports using generic LLMs as safety evaluators in the form of an LLM-as-a-Judge mode for both open- and closed-weight models.\nEvaluating judges is just as important as evaluating the LLMs themselves, as a poorly performing judge may lead to erroneous safety measures Zheng et al. (2024  ###reference_b25###). Thus, WalledEval additionally facilitates the benchmarking of judges by comparing judge predictions against gold-standard labels. We also release HIXSTest, a manually curated small dataset in Hindi consisting of 25 safe and unsafe prompts each, to further challenge judges 444https://hf.co/datasets/walledai/HiXSTest  ###reference_###.\nMutations. Style-based mutations of prompts have been previously observed to trigger different safety behaviors. For example, ChatGPT-4o refuses to answer the question \u2018How to make a Molotov cocktail?\u2019 but responds helpfully to its past tense-mutated form \u2018How did people make a Molotov cocktail?\u2019 Andriushchenko and Flammarion (2024  ###reference_b4###). WalledEval introduces mutators, allowing one to obtain a range of off-the-shelf text-style mutations. WalledEval hosts mutators that can transform tense, alter sentence structures, insert noise (misspellings), and paraphrase text.\nAs a framework, WalledEval supports a range of off-the-shelf open- and closed-weight LLMs (e.g., Llamas and ChatGPTs) with custom testing support for any Transformers-based LLM properties, such as chat templates. It supports a range of LLM-as-a-Judge functionalities, such as adding a custom judge, converting a generic LLM into a safety judge, and benchmarking the judges. Additionally, it allows for the multi-faceted augmentation of existing benchmarks by performing strategic mutations with mutators, aiding extensive safety audits of the models."

+    "abstract": "Abstract\nMagnetic resonance imaging (MRI) relies on radiofrequency (RF) excitation of proton spin. Clinical diagnosis requires a comprehensive collation of biophysical data via multiple MRI contrasts,\nacquired using a series of RF sequences that lead to lengthy examinations. Here, we developed a vision transformer-based framework that captures the spatiotemporal magnetic signal evolution and decodes the brain tissue response to RF excitation, constituting an MRI on a chip. Following a per-subject rapid calibration scan (28.2 s), a wide variety of image contrasts including fully quantitative molecular, water relaxation, and magnetic field maps can be generated automatically. The method was validated across healthy subjects and a cancer patient in two different imaging sites, and proved to be 94% faster than alternative protocols. The deep MRI on a chip (DeepMonC) framework may reveal the molecular composition of the human brain tissue in a wide range of pathologies, while offering clinically attractive scan times.",

The system includes a vision transformer[36  ###reference_b36###, 37  ###reference_b37###] with a dual-domain input, comprised of RF excitation information and real-world tissue response image counterparts. An extension module was also designed, which quantifies six biophysical tissue parameters across the entire 3D brain, without the need for any additional input.\nThe core module inputs are a sequence of m=6 non-steady-state MRI calibration images and an RF excitation parameter tensor (Fig. 1a). The tensor includes two concatenated parts: the acquisition parameters used for obtaining the calibration images and the desired on-demand parameters for the subsequent image output. Separate embeddings for the real-image-data and the physical RF properties are then learned using a vision transformer and a fully connected layer, respectively. The quantification module, involves a transfer learning strategy where the core module weights are plugged-in, the last layer is removed, and there is augmentation of two new convolutional layers. Ground truth reference data are then used to instigate quantification-oriented learning (Fig. 1b).\nThe DeepMonc framework was trained using 3,118,692 image and acquisition parameter pairs from 9 healthy human volunteers, scanned at a single imaging site (Tel Aviv University) on a 3T MRI (Prisma, Siemens Healthineers) equipped with a 64-channel coil. The framework was then tested using 30,324 image and acquisition parameter pairs obtained from 4 other subjects representing three challenging datasets: (i) Two healthy subjects not used for training (scanned at the same site). (ii) A brain cancer patient scanned at a different imaging site (Erlangen University Hospital). (iii) A healthy volunteer scanned using different hardware and MRI model at a different imaging site (Erlangen University Hospital, Trio MRI with a 32 channel coil)."

The full reference imaging protocol consisted of 30 pseudo-random RF excitations (Supporting Information Fig. 1)[26  ###reference_b26###]. The first six images were used for per-subject calibration, followed by DeepMonC predictions of the multi-contrast images associated with the next six response images (Fig. 1a).\nA representative example of the DeepMonC output compared to the ground truth for each of the validation datasets is shown in Fig. 2 and whole-brain 3D reconstruction output is provided as Supporting Information Movies M1 (semisolid MT) and M2 (amide). An excellent visual, perceptive, and pixelwise similarity was obtained between DeepMonC output and ground truth. This is reflected by a structural similarity index measure (SSIM)  0.96, peak signal-to-noise ratio (PSNR)  36, and normalized mean-square error (NRMSE)  3% (Table 1).\nTo evaluate the ability to generate an up to 4-times longer output compared to the input, the process was continued recursively, until the entire 30-long sequence was predicted based on the first six calibration images (Supporting Information Movies M3 (semisolid MT) and M4 (amide)). Although there were some errors in the last six images, the overall performance remained high, with a structural similarity index measure (SSIM)  0.94, peak signal-to-noise ratio (PSNR)  32, and normalized mean-square error (NRMSE)  3.7% (Table 1). The inference times for reconstructing whole brain 6 or 24 unseen image contrasts were 7.674 s and 10.896 s, respectively, when using an Nvidia RTX 3060 GPU, and 9.495 s and 19.55 s, respectively, when using a desktop CPU (Intel I9-12900F)."

The DeepMonC reconstructed paramater maps were visually, perceptually, and quantitatively similar to the ground truth reference (Fig. 3-5 panels a,b and Supporting Information Figure S2). The reconstruction performance was highest for the test subject scanned by the same scanner used for training (SSIM = 0.9190.024; PSNR = 30.1971.808; NRMSE = 0.0490.008), followed by the cancer patient (unseen pathology at an unseen imaging site: SSIM = 0.884; PSNR = 26.3491.246; NRMSE = 0.0590.007), and the unseen subject scanned using unseen hardware at an unseen imaging site (SSIM = 0.8110.044; PSNR = 24.1861.523; NRMSE = 0.0760.011).\nThe magnetic field maps reconstructed by DeepMonc exhibited improved homogeneity compared to their ground-truth counterparts (Fig. 3,4,5 panels a and b). This enabled successful artifact removal from the semisolid MT proton volume fraction and exchange rate maps, which are known to be sensitive to B0 and B1 inhomogeneity[38  ###reference_b38###, 39  ###reference_b39###, 40  ###reference_b40###] (white arrows in Fig. 3, and Fig. 5).\nTo analyze the contribution of the decoded tissue response information, captured by DeepMonc core module, to the quantification task performance, a comparison with standard supervised learning was performed. The same quantification architecture (Fig. 1b) was trained to receive the exact same inputs, and then output the same six quantitative biophysical parameter maps, but without employing the pre-trained DeepMonC weights (learnt by the core module, Fig. 1a). This standard supervised learning routine yielded parameter maps with a markedly lower resemblance to the ground truth (Fig. 3,4,5 panel c). The deterioration in output was accompanied by a statistically significant lower SSIM (0.8050.057, 0.7780.062, 0.7250.066, for the unseen subject, pathology, and hardware datasets, respectively, p0.0001, n=68 image pairs) and PSNR (25.7331.473, 23.5461.428, 22.6141.342, for the three datasets, respectively, p0.0001, n=68 image pairs), and a higher NRMSE (0.08420.0125, 0.08430.0128, 0.0920.012 for the three datasets, respectively, p0.0001, n=68 image pairs, Fig. 3,4,5 panel d). The inference time required for reconstructing whole brain quantitative images was 6.751 s or 9.822 s when using an Nvidia RTX 3060 GPU or a desktop CPU (Intel I9-12900F), respectively."

+            "text": "The past few decades have seen increased reliance on MRI for clinical diagnosis[41  ###reference_b41###]. In parallel, this has required the introduction of new contrast mechanisms and dedicated pulse sequences[42  ###reference_b42###, 43  ###reference_b43###, 44  ###reference_b44###, 10  ###reference_b10###, 45  ###reference_b45###, 46  ###reference_b46###, 47  ###reference_b47###]. While offering biological insights and improved diagnosis certainty, the integration of these sequences into routine MRI examinations exacerbates the already lengthy overall scan times. Here, we describe the development of a deep-learning-based framework that can rapidly decode the human brain tissue response to RF excitation. The system generates a variety of on-demand image contrasts in silico that faithfully recapitulate their physical in-vivo counterparts (hence, termed a deep MRI on a chip).\nThe target contrasts requested from DeepMonC were associated with RF parameters extrapolated beyond the range of the training parameters, thereby representing a highly challenging task (Supporting information Fig. 1). Nevertheless, an excellent agreement between the generated and ground-truth image-sets was obtained (Fig. 2 and Table 1). The dependence of DeepMonC on the particular set of calibration images used and the desired output contrast was assessed on 18 different input-output pairs (Supporting Information Figure S3). Despite some variability, a satisfactory reconstruction was obtained in all cases (SSIM  0.96, PSNR  36, NRMSE  2%). Importantly, DeepMonC was able to overcome unknown initial conditions, as all calibration image-set combinations but one (image indices 1-6, Supporting Information Figure S3) were acquired following an incomplete magnetization recovery.\nThe core module architecture was designed for image translation of m-to-m size (Fig. 1a, illustrated for m=6). Nevertheless, it can be recursively applied (by using the model\u2019s output as the next input for generating another set of m images), and maintains an attractive performance, for up to m-to-3m translations (Supporting Information Movies M3 and M4). Although some errors were visually observed when attempting m-to-4m translation (in the last m=6 images), additional training with longer acquisition protocols could further improve this performance.\nThe excellent on-demand contrast generation performance exhibited by DeepMonC (Table 1) can be attributed to two key factors: (1) The introduction of explicit (and varied) acquisition parameter descriptors into the training procedure; this information is traditionally overlooked and hidden from MR-related neural networks[48  ###reference_b48###, 49  ###reference_b49###]. (2) The incorporation of visual transformers as the learning strategy. These enable the system to address the double sequential nature of the image data obtained from both the 3D spatial domain and the temporal (spin-history) domain. Visual transformers, with their effective attention mechanism, are not only capable of capturing long-range data dependencies but can also understand global image context, alleviate noise, and adapt to various translational tasks[37  ###reference_b37###, 50  ###reference_b50###].\nContrast-weighted imaging is the prevalent acquisition mode in clinical MRI. However, it has become increasingly clear that quantitative extraction of biophysical tissue parameters may offer improved sensitivity, specificity, and reproducibility[51  ###reference_b51###, 52  ###reference_b52###, 53  ###reference_b53###]. By harnessing the decoded brain tissue response to RF excitation, the DeepMonC framework was further leveraged to simultaneously map six quantitative parameters (Fig. 3-5), spanning three different biophysical realms, namely water relaxation, semisolid macromolecule proton exchange, and magnetic field homogeneity. The results provide an excellent agreement with the ground truth (Fig. 3-5d, Supporting Information Fig. S2), as well as an inherent ability to mitigate artifacts (white arrows in Fig. 3 and Fig. 5). Specifically, the B0 and B1 maps generated by DeepMonC exhibit better homogeneity than the reference ground truth. This thereby represents a practical explanation for the successful reduction of hardware/in-homogeneity related noises around the sinuses/eyes and at the air-tissue interfaces.\nImportantly, the rich whole-brain information provided by DeepMonc was reconstructed in only 6.8 seconds, following a non-steady state rapid acquisition using a single pulse sequence of 28.2 s. This represents a 94% acceleration compared to the state of the art ground-truth reference (acquired in 8.5 min, Fig. 1b). Interestingly, the quantification task results were even less sensitive to the particular pulse sequence used for acquiring the calibration images (Supporting Information Figure S4) than the on-demand contrast generation task (Supporting Information Figure S3).\nThe success of the quantification module is directly associated with the reliance on DeepMonC\u2019s core pre-training, which generates a comprehensive understanding of the RF-to-tissue relations. This is supported by the statistically significant higher performance obtained by the quantification module compared to the vanilla use of DeepMonC (untrained) architecture (Fig. 3-5 panels c,d, n=68 image slices, p0.0001).\nThe generalization of DeepMonC predictions was assessed on three datasets, each representing a different challenge. Overall, there proved to be compelling evidence for generalization, with a faithful representation of the the RF-to-tissue interface, with a satisfactory image reconstruction obtained in all cases. It should however be noted that, as expected, the parameter quantification of the unseen subject scanned at the same site and scanner used for training, yielded the best results. The cancer patient scanned at a different image site yielded the next best performance (only healthy volunteers were used for training), followed by the healthy subject scanned using a different scanner model and hardware at a different imaging site (Fig. 3-5d, Supporting Information Fig. S4). When assessing the on-demand contrast generation task performance, the differences between the various test-sets were much less discernible, with mostly subtle variations in the reconstruction metrics (Table 1). In the future, additional training using subjects scanned on other scanner models and across various pathologies could further boost the framework performance.\nSaturation transfer (encompassing both CEST and semisolid MT) is the dominant biophysical mechanism involved in the on-demand contrast generation task. This was chosen as a representative emerging imaging approach that is the focus of much interest from across the medical community[10  ###reference_b10###, 54  ###reference_b54###, 55  ###reference_b55###, 56  ###reference_b56###, 57  ###reference_b57###, 58  ###reference_b58###, 59  ###reference_b59###]. Nevertheless, the same conceptual framework could potentially be applied for generating on-demand diffusion, perfusion, relaxation, susceptibility, and other contrast-weighted images, given that a per-subject rapidly acquired data from the same general mechanism of interest is provided, alongside the matching acquisition parameters. Notably, a single pulse sequence may represent several biophysical properties, similarly to the way that ST-contrast weighted images are affected by the T1, T2, B0, and B1. Furthermore, while this work was focused on brain imaging, we expect that the same framework could be similarly utilized in other organ/tissues (after proper training). Finally, the ground-truth reference used for the quantification task was obtained via standard water proton relaxometry, magnetic field-mapping, and semisolid MT MRF. However, the same quantification module could seamlessly be trained using alternative reference modalities, such as 31P-imaging (for reconstructing intracellular pH maps)[60  ###reference_b60###], or even non-MR images (such as Ki-67 proliferation index histological images), thereby creating new cross-modality insights and opportunities.\nIn summary, we have developed and validated a computational framework that can learn the intricate mapping between the magnetic resonance RF irradiation domain and the subject-specific image domain. The method is biophysical-model-free and thus, unbiased by pre-existing parameter restrictions or assumptions. Given its ultra-fast on-demand contrast generation ability, we expect this approach to play an important role in the efforts to accelerate clinical MRI."

+    "title": "PEDAL: Enhancing Greedy Decoding with Large Language Models using Diverse Exemplars",
+    "abstract": "Self-ensembling techniques with diverse reasoning paths such as Self-Consistency have demonstrated remarkable performance gains in text generation with Large Language Models (LLMs). However, such techniques depend on the availability of an accurate answer extraction process to aggregate across multiple outputs. Moreover, they acquire higher inference cost, in comparison to Greedy Decoding, due to generation of relatively higher number of output tokens. Research has shown that the free form text outputs from Self-Consistency can be aggregated reliably using LLMs to produce the final output. Additionally, recent advancements in LLM inference have demonstrated that usage of diverse exemplars in prompts have the ability to induce diversity in the LLM outputs. Such proven techniques can be easily extended to self-ensembling based approaches to achieve enhanced results in text generation. In this paper, we introduce PEDAL (Prompts based on Exemplar Diversity Aggregated using LLMs), a hybrid self-ensembling approach, that combines the strengths of diverse exemplar based prompts and LLM based aggregation to achieve improvement in overall performance. On the publicly available SVAMP and ARC datasets, our experiments reveal that PEDAL can achieve better accuracy than Greedy Decoding based strategies with lower inference cost compared to Self Consistency based approaches.",

+            "text": "Large Language Models (LLMs) Brown et al. (2020  ###reference_b3###); Raffel et al. (2020  ###reference_b28###); Chowdhery et al. (2022  ###reference_b11###); Touvron et al. (2023  ###reference_b33###) have been proven to show remarkable performance in a wide range of Natural Language Understanding tasks Zhao et al. (2023  ###reference_b41###) as a result of their outstanding reasoning capabilities Wei et al. (2022  ###reference_b35###); Zhou et al. (2022  ###reference_b43###).\nHowever, they still rely on carefully designed prompts to achieve optimal performance Khattab et al. (2023  ###reference_b20###); Fernando et al. (2023  ###reference_b14###). To realize further improvement in LLM reasoning, Wang et al. (2022  ###reference_b34###) proposed a self-ensembling technique termed \u201cSelf-Consistency\u201d(SC) where diverse \u201cChain-of-Thought\u201d(CoT) Wei et al. (2022  ###reference_b35###) reasoning paths were generated and then aggregated to construct an accurate and reliable response. This approach has been successfully extended to various use-cases such as LLM hallucination detection Chen et al. (2024  ###reference_b6###), medicineZhou et al. (2024  ###reference_b44###) and code generation Huang et al. (2024  ###reference_b17###).\nWhile SC based approaches can significantly improve the robustness of LLM outputs, one of their common drawbacks is that they perform best on a fixed answer set Wang et al. (2022  ###reference_b34###) or rely on training custom aggregation methods to measure consistency across multiple text outputs. To address this, Chen et al. (2023b  ###reference_b8###) proposed \u201cUniversal Self Consistency\u201d(USC), an extension of SC, that aggregated the text outputs by re-invoking the LLM. Essentially, USC prompted the LLM to select the most consistent response among the different candidate answers generated by SC and demonstrated that it can achieve improved performance. However, this still leaves us with another drawback of SC which is the cost involved in generating the outputs. Concretely, SC involves generating long and diverse reasoning paths which results in a higher number of output tokens compared to Greedy Decoding based approaches. The cost of output token generation with LLMs is typically more than input token processing due to the difference in the number of forward passes Shazeer (2019  ###reference_b31###); Chng (2024  ###reference_b10###) resulting in a higher inference cost with SC.\nLi et al. (2023b  ###reference_b22###) experimented with usage of diverse exemplars in the LLM prompts and combined them with diverse reasoning paths in SC to achieve more accurate results in text generation. We observe that if we leverage diverse exemplars with Greedy Decoding for text generation and aggregate the responses as in USC, we achieve better performance than traditional Greedy Decoding in terms of accuracy while also achieving lower cost of inference in comparison to SC based approaches.\nIn this paper, we present a hybrid self-ensembling approach, PEDAL(Prompts based on Exemplar Diversity Aggregated using an LLM), that offers a trade-off between the Greedy Decoding and SC in terms of accuracy and cost efficiency. We leverage diverse exemplars in LLM prompts to generate multiple candidate responses using Greedy Decoding and then aggregate them using an LLM to generate the final response. On two publicly available datasets, we demonstrate that PEDAL achieves better accuracy than Greedy Decoding based strategies and offers lower cost in inference compared to SC based strategies.\nRest of the paper is organized as follows: In\nSection 2  ###reference_###, we describe previous work for solving similar problems. Section 3  ###reference_### explains our proposed strategy in detail followed by Section 4  ###reference_### where we describe the data and the experiment settings to validate PEDAL. We then present our results and analyses in Section 5  ###reference_###. Finally, in Section 6  ###reference_###, we summarize our findings and discuss potential future work."

With Llama3, USC processes an average of 694 input tokens and 924 output tokens while PEDAL processes 1,262 input tokens and 198 output tokens.

Surprisingly, USC achieves an accuracy of 71.88% which is relatively the least among the strategies. With USC, the main goal of the paper is to benchmark the proposed approach in terms of token count. To prevent diverging from the primary focus area, we leave deeper analysis of this behaviour to future work.\nAs shown in Table 5  ###reference_###, with Qwen2, our approach outperforms USC where USC processes roughly 1,154 input tokens and 669 output tokens on an average while PEDAL processes 1,180 input tokens with 100 output tokens.

With Qwen2, we observe that PEDAL would be more cost efficient for the ARC dataset but may prove to be more expensive for the SVAMP dataset in comparison to CoT.

In future work, we plan to explore possibilities on extending such ensembling strategies to a wider range of problem settings involving free-form text generation to further deep dive into strengths and weaknesses of our proposed system."

+            "text": "The analysis of climate-economy policies is typically performed using Integrated Assessment Models (IAMs) that describe the complex interplay between the climate and the economy via deterministic equations.\nIn order to account for stochastic shocks when finding optimal mitigation policies adapted to climate and economic variables that are evolving stochastically over time, a recursive dynamic programming implementation of integrated assessment models is required.\nThis is a significantly harder computational problem to solve compared to the deterministic case.\nSeminal contributions to solving IAMs as optimal decision making problems in the presence of uncertainty include Kelly and Kolstad (1999  ###reference_b18###), Kelly and Kolstad (2001  ###reference_b19###), Leach (2007  ###reference_b23###), Traeger (2014  ###reference_b35###), and Cai and Lontzek (2019  ###reference_b7###).\nAll these studies are based on variants of the so-called dynamic integrated climate-economy (DICE) model extended to include stochastic shocks to the economy and climate.\nThe DICE model is one of the three main IAMs (the other two being FUND and PAGE) used by the United States government to determine the social cost of carbon; see Interagency Working Group on Social Cost of Greenhouse\nGases (2016  ###reference_b16###).\nIt has been regularly revised over the last three decades, with the first version dating back to Nordhaus et al. (1992  ###reference_b28###).\nIt balances parsimony with realism and is well documented with all published model equations; in addition, its code is publicly available, which is an exception rather than the rule for IAMs.\nAt the same time, it is important to note that IAMs, and the DICE model in particular, have significant limitations (in the model structure and model parameters), which have been criticized and debated in the literature (see the discussions in Ackerman et al. (2009  ###reference_b1###); Pindyck (2017  ###reference_b29###); Grubb et al. (2021  ###reference_b13###); Weitzman (2011  ###reference_b37###)).\nDespite the criticism, the DICE model has become the iconic typical reference point for climate-economy modeling, and is used in our study.\nThe original deterministic DICE model is solved as a global optimization problem using the General Algebraic Modeling Language (GAMS)111https://www.gams.com/  ###reference_www.gams.com/###, a high-level programming language for mathematical modeling.\nIts stochastic extensions mentioned in the above-mentioned studies require implementations of recursive dynamic programming to find optimal climate policies under uncertainty222If required, the deterministic DICE model can be solved as a recursive dynamic programming problem, too..\nThis is subject to the curse of dimensionality, and these studies are limited to only one or two stochastic variables.\nEven in this case, computations take several million core hours on a modern supercomputer (see, for instance, Cai and Lontzek (2019  ###reference_b7###)).\nTherefore, simulation methods are needed to handle models with many state variables and multiple shocks to reduce the computational burden.\nThe least-squares Monte Carlo (LSMC) method for solving multi-dimensional stochastic control problems has gained popularity in recent years due to its effectiveness in dealing with high dimensional problems and because it imposes fewer restrictions on the constraints and allows for flexibility in the dynamics of the underlying stochastic processes.\nThe idea is based on simulating random paths of the underlying stochastic variables over time and replacing the conditional expectation of the value function in the Bellman backward recursive solution of the stochastic control problem with an empirical least-squares regression estimate.\nThe transition density of the underlying process is not even required to be known in closed form; one just needs to be able to simulate the underlying processes.\nThe LSMC method was originally developed in Longstaff and Schwartz (2001  ###reference_b24###) and Tsitsiklis and Van Roy (2001  ###reference_b36###).\nThe convergence properties of this method are examined in Belomestny et al. (2010  ###reference_b6###); Belomestny (2011  ###reference_b5###), and A\u00efd et al. (2014  ###reference_b2###).\nThe LSMC method was originally developed for pricing American options where the state variables are not affected by the control.\nLater, an extension of the LSMC method with control randomisation was developed in Kharroubi et al. (2014  ###reference_b20###) to handle endogenous state variables (i.e. state variables that are affected by controls).\nWhen applied to stochastic control problems that aim to optimize an expected utility, some further extensions are needed as proposed in Andr\u00e9asson and Shevchenko (2022  ###reference_b3###) and Andr\u00e9asson and Shevchenko (2024  ###reference_b4###) to achieve a stable and accurate solution.\nIn this paper, we demonstrate how the LSMC method can be adapted to solve the recursive dynamic programming problem of stochastic IAMs.\nWe exemplify this approach with an application to the DICE model with uncertainties in: (1) the equilibrium temperature sensitivity, (2) the damage function coefficient, (3) the growth rate of total factor productivity, (4) the growth rate of decarbonization, and (5) the equilibrium carbon concentration in the upper strata.\nThese five uncertainties were identified in Nordhaus (2018  ###reference_b26###) as being major sources of uncertainty for the evolution of climate-economic state variables.\nTypically, polynomial regression is used in LSMC to approximate the corresponding conditional expectations with respect to state variables and controls.\nHowever, for models such as the stochastic DICE model, this leads to the need of too many covariates and simulations, making the method not practical.\nTo overcome this problem, we use deep neural network approximations for the required regressions and provide detailed explanations.\nThe DICE model is a deterministic approach that combines a Ramsey\u2013Cass\u2013Koopmans neoclassical model of economic growth (also known as the Ramsey growth model) with a simple climate model.\nIt involves six state variables (economic capital; temperature in atmosphere and lower oceans; carbon concentration in atmosphere, upper and lower oceans) evolving deterministically in time, two control variables (savings and carbon emission reduction rates) to be determined for each time period of the model, and several exogenous processes (e.g. population size and technology level).\nThe uncertainty about the future of the climate and economy is then typically assessed by treating some model parameters as random variables (because we do not know the exact true value of the key parameters) using a Monte Carlo analysis (see Nordhaus (2018  ###reference_b26###); Gillingham et al. (2015  ###reference_b12###)).\nModeling uncertainty owing to the stochastic nature of the state variables (i.e. owing to the process uncertainty that is present even if we know the model parameters exactly) requires the development and solution of the DICE model as a dynamic model of decision-making under uncertainty, where we calculate the optimal policy response under the assumption of continuing uncertainty throughout the time frame of the model.\nFew attempts have been made to extend the DICE model to incorporate stochasticity in the underlying state variables and solve it as a recursive dynamic programming problem.\nFor example, Kelly and Kolstad (1999  ###reference_b18###) and Leach (2007  ###reference_b23###) formulated the DICE model with stochasticity in the temporal evolution of temperature, and solved this as a recursive dynamic programming problem.\nThese studies are seminal contributions to the incorporation of uncertainty in the DICE model (although their numerical solution approach is difficult to extend to a higher dimensional space and time-frequency).\nCai and Lontzek (2019  ###reference_b7###) formulate DICE as a dynamic programming problem with a stochastic shock on the economy and climate.\nIn addition, Traeger (2014  ###reference_b35###) developed a reduced DICE model with a smaller number of state variables, whereas Lontzek et al. (2015  ###reference_b25###) studied the impact of climate tipping points, and Shevchenko et al. (2022  ###reference_b32###) considered the DICE model with discrete stochastic shocks to the economy.\nTo our best knowledge, the only attempt to solve the stochastic DICE model using an LSMC-type approach is Ikefuji et al. (2020  ###reference_b15###).\nTheir study handles only one uncertainty at a time, and the setup of the regression type Monte Carlo algorithm omits the integration for the conditional expectation in the Bellman equation, assuming the randomness is known in the transition of state variables (in principle, in this case, the required integration can be performed by using deterministic quadrature methods, but this will be subject to the curse of dimensionality).\nThe primary contributions of our paper are as follows:\nWe introduce an efficient approach for modeling stochastic climate-economy models by combining the least-squares Monte Carlo method with deep learning techniques. It provides flexibility in handling various types of uncertainties, including both parametric and stochastic process uncertainties.\nWe formulate a stochastic version of the DICE model using the sources of uncertainty as identified by Nordhaus (2018  ###reference_b26###). Notably, it does not rely on discretizing the underlying probability distributions that is usually performed in Monte-Carlo type analyses for the sake of model tractability.\nWe perform comprehensive numerical experiments and discuss numerical techniques to significantly reduce the computational burden and address several peculiarities of the model. Moreover, we demonstrate how to perform uncertainty quantification (UQ) to understand how uncertainties in the model propagate and affect outputs (such as projections for the evolution of atmospheric temperature).\nThe paper is organized as follows.\nSection 2  ###reference_### gives a description of the considered model.\nSection 3  ###reference_### describes the numerical method used to solve the model.\nSection 4  ###reference_### provides a comprehensive numerical study.\nSection 5  ###reference_### concludes."

Assuming a Cobb-Douglas production function, the growth in total factor productivity  models the growth in output that is not explained by growth in inputs of labor and capital used in production.\nThe DICE model assumes  evolves according to , where  is the deterministic growth rate which is specified in Table 1  ###reference_###.\nNordhaus (2018  ###reference_b26###) assumes  is normally distributed with mean  and standard deviation .\nBut in this case, using the dynamics for the growth rate, we can model  as normally distributed with mean  and standard deviation .\nIn order to remove extreme cases, we truncate this distribution at the mean  two standard deviations.\nThe evolution of  is shown in Figure 1  ###reference_###.\n###figure_1### The rate of decarbonization.

The equilibrium temperature sensitivity measures how much the Earth\u2019s surface will warm in response to a doubling of atmospheric .\nThe DICE model assumes the ETS is equal to  for an equilibrium  doubling.\nIn Table 1  ###reference_###, the ETS corresponds to the denominator in the definition of .\nNordhaus (2018  ###reference_b26###) models the ETS as a log-normal distribution,  with .\nWe do the same, truncating at the mean  two standard deviations.\nThe damage function. The DICE model assumes climate-induced economic damages are a quadratic function of the increase in atmospheric temperature.\nIt is modeled as a fractional loss of global output from greenhouse warming, , where  denotes a damage coefficient representing the severity of the economic impact of global warming.\nThe DICE model assumes  to be equal to 0.00236.\nNordhaus (2018  ###reference_b26###) models the  by a normal distribution with mean 0.00236 and standard deviation 0.00118.\nWe use the same distribution but truncate it at the mean minus one standard deviation, and at the mean plus two standard deviations.\nThe carbon cycle. The carbon cycle coefficient models the equilibrium concentration of carbon in the biosphere and upper level of the oceans.\nThe DICE model assumes it to be equal to 360 gigatonnes of carbon (GtC).\nIn Table 1  ###reference_###, it corresponds to the value 360 appearing in the definitions of  and .\nNordhaus (2018  ###reference_b26###) models this coefficient as a log-normal distribution,  with \nWe do the same, truncating at the mean  two standard deviations.\n###figure_3### Another type of uncertainty is parametric uncertainty, where the value of a coefficient can change over time as it is re-drawn at each point in time.\nThis type of uncertainty lies between the stochastic process and the initial parameter uncertainty.\nAlthough we did not include it in our study, it is straightforward to incorporate and solve using our method.\nAssuming  implies a roughly  probability of  being negative.\nThis is a non-negligible scenario.\nGiven that the DICE model aims to combine equations for the economy and climate, it is highly questionable to assume the damage coefficient could be below or just above zero.\nMoreover, the assumption of a log-normal distribution for the equilibrium temperature sensitivity and the carbon cycle coefficient also entails a non-negligible probability of those coefficients being close to zero.\nNordhaus (2018  ###reference_b26###) avoids this issue by discretizing the distributions, separating them into quintiles, and then calculating the expected values of the random variables within those quintiles.\nThese expected values are taken as realizations of discrete uncertain variables, yielding sufficiently positive lowest realizations for the coefficients.\nInspired by this approach, we also truncate the distributions of the random variables, however, without discretizing them.\nThis avoids issues with too low damage coefficients and temperature sensitivities, as well as extreme growth rates for total factor productivity and carbon intensity."

(2020  ###reference_b15###) formulate a stochastic version of the DICE model considering one uncertainty at a time: a) uncertainty in the damage-abatement fraction, b) uncertainty in the damage parameter, c) uncertainty in the emissions-to-output ratio, and d) uncertainty in total factor productivity .\nThese uncertainties are introduced by multiplying the corresponding deterministic DICE variables by stochastic disturbances.\nThus, the number of state variables is the same as in the deterministic DICE (6).\nTo the best of our knowledge, this is the only attempt to solve a stochastic version of the DICE model by using an LSMC type approach.\nThey use least-squares regression with polynomial basis functions to approximate the value function, i.e. in the spirit of regress later LSMC.\nHere, we note that their regression type Monte Carlo algorithm setup omits the integration for the conditional expectation in the Bellman equation, assuming the random disturbance is known in the transition of state variables.\nIn principle, the standard regress later LSMC can be implemented here to handle this type of uncertainty but it will be a subject of the curse of dimensionality in the case of more than one shock.\nFriedl et al. (2023  ###reference_b11###) present a method for solving integrated assessment models and performing uncertainty quantification.\nThey exemplify their approach on a version of the DICE model with uncertainties in equilibrium temperature sensitivity (that contains a Bayesian learning component), and the damage function (represented by a stochastic tipping process).\nFirst, a deep neural network is trained to output, in particular, the optimal policies and value function at a given point in time, and then a Gaussian process-based model is trained to approximate quantities of interest such as the social cost of carbon in order to speed up the evaluation when calculating UQ metrics.\nIn contrast to Friedl et al. (2023  ###reference_b11###), our method approximates the conditional expectation rather than the policy functions, and then finds those by running an optimizer to solve Equation (9  ###reference_###).\nApproximating  by a regression scheme is a challenging task, since the presence of the bounds (i.e. ) require a very careful choice of an appropriate regression scheme that can effectively interpolate the optimal policy, especially in the presence of extended periods when the policy is on the boundary.\nOur approach avoids this issue by finding the optimal policy through an optimizer which, once the conditional expectation has been approximated, can be performed with a high degree of numerical precision and speed.\nMoreover, the deep LSMC method requires performing a least-squares regression, where the loss function is the squared distance between the object of interest and the neural network prediction.\nThis choice of loss function is significantly simpler, as it avoids the eleven individual components that enter the loss function based on an elaborate set of first-order conditions that are needed in the solution of Friedl et al. (2023  ###reference_b11###).\nFinally, in contrast to Friedl et al. (2023  ###reference_b11###), we find that there is no need to train an additional Gaussian process-based surrogate model to perform UQ for the quantities of interest (such as the social cost of carbon).\nOnce the backward recursion (Equation (8  ###reference_###)) has been performed, a large amount of optimal trajectories for different realizations of uncertainties can be computed easily in order to perform UQ for the quantities of interest."

conditional expectations.\nFor clarity, we emphazise that our state vector  consists of 11 variables: the six variables from the deterministic formulation of the DICE model (, , ), the two stochastic processes  and , as well as the three parameters discussed in Subsection 2.1  ###reference_### (temperature-sensitivity coefficient, damage coefficient and carbon cycle coefficient).\nFor the backward recursion and least-squares approximation of the value function, we use  sample points in the 11-dimensional state space.\nFigure 6  ###reference_### is based on  forward trajectories, while the statistics reported in Table 2  ###reference_### are based on a sample of size .\nTo find the optimal policies in (9  ###reference_###), we use the limited-memory Broyden\u2013Fletcher\u2013Goldfarb\u2013Shanno algorithm with box constraints (L-BFGS-B).\nOn a 64 core machine, it took between 9 hours (for  samples) and 18 hours (for  samples) to perform the backward recursion.\nComputing optimal forward trajectories then typically took around 15 minutes for  trajectories, and 1 hour for  trajectories.\nThe initial year for the version of DICE model used in Nordhaus (2018  ###reference_b26###) is 2015, not 2020.\nFor illustration purposes, during calculation of the optimal forward trajectories, we made the first policy decision  deterministic and equal to the optimal decision in the deterministic version of the model.\nThis amounts to starting the forward trajectories in the year 2020 with initial values that correspond to the optimal deterministic DICE states identified in Nordhaus (2018  ###reference_b26###).\nMoreover, the original DICE model is formulated as an infinite-horizon control problem, see Equation (1  ###reference_###).\nHowever, our formulation of the LSMC method as discussed in Section 3  ###reference_### assumes a finite time horizon with  time steps ( in our case corresponding to  being the year 2015, and  being the year 2500).\nImposing a finite time horizon corresponds to a truncation of the problem, and one needs to choose an appropriate boundary reward function .\nSimilarly, as in Cai and Lontzek (2019  ###reference_b7###), our terminal reward function is computed by assuming that after 2500 the policies are fixed to , , and that the system evolves deterministically.\nThe reward is then equal to the discounted sum of population-weighted utility of per-capita consumption from following the fixed policies for another 100 time steps.\nDue to discounting and the large amount of time steps, it is assumed that a different choice of boundary reward that far ahead in the future should have a negligible impact on results for the twenty-first century.\nFor approximating conditional expectations, we use deep feedforward neural networks with two hidden layers, each containing 32 hidden nodes with hyperbolic tangent (tanh) as activation function, and a linear readout in the output layer.\nNeural network training is performed using minibatch stochastic gradient descent with the Adam optimizer.\nThe initial learning rate is set to  and reduced to a minimum of  during training.\nEarly stopping is implemented to avoid overfitting.\nDuring the backward recursion, the trained neural network from one step (e.g. step ) is used as the initial neural network for the next step\u2019s training (step ), which reduces computation time.\nFor this version of the stochastic DICE model, the transition equation (7  ###reference_###) can be separated into two transitions:\nwhere the deterministic transition to the post-decision variable  precedes the transition .\nThis allows the conditional expectation in (8  ###reference_###) to be simplified to:\nThis method offers two main advantages: (1) dimension reduction in the covariates needed for the least-squares approximation of the conditional expectation, and (2) an increase in sampling efficiency by sampling only the post-decision states  rather than both  and .\nOur method benefits significantly from using post-decision variables, and we found a notable improvement in numerical precision.\nEconomic capital  and total factor productivity  can grow quite rapidly over time, especially in scenarios where large growth in  meets a low consumption rate .\nThis poses an important numerical challenge, since an appropriate domain for sampling the state variables needs to be chosen with care.\nA popular solution to this issue, having been applied successfully in Jensen and Traeger (2014  ###reference_b17###), is to normalize economic capital as follows.\nFirst, we re-write output to express it in terms of labor-augmenting technology: , where .\nLet  denote the deterministic trajectory of , where  is fixed to be equal to the expected value.\nEconomic capital and output are then expressed in terms of units of effective labor: , and .\nThe state variable  can also be substituted by  and further normalized to .\nIn our simulations, we found that these normalization steps had a favorable impact on the precision of the numerical results.\nCalculating the social cost of carbon (5  ###reference_###) requires knowledge of partial derivatives of the value function with respect to atmospheric carbon concentration and economic capital.\nSince we do not have an analytic representation of the value function, we follow an approximation approach that was discussed in Traeger (2014  ###reference_b35###), where Chebychev polynomials were used to approximate the value function.\nAt each time , we approximate the value function  by a neural network:\nfor a suitable parameter vector .\nThis approach strikes a balance between numerical precision and analytical tractability, applicable even in the presence of stochasticity.\nNote that the idea of approximating the value function by a neural network has already been carried out in Kelly and Kolstad (2001  ###reference_b19###) where, however, the neural network approximation was not used for computing the social cost of carbon.\nThe post-decision variables , representing the states  after decision , have the same dimension as .\nThe sampling step in Algorithm 1  ###reference_### requires choosing an effective sampling distribution.\nOne standard approach would be to put a high-dimensional grid of uniformly drawn points around the deterministic DICE solution.\nHowever, in order to improve numerical precision, low-discrepancy grids are favourable in order to keep the number of sample points needed to a reasonable amount.\nLatin hypercube sampling offers a more favourable distribution of grid points compared to uniform sampling.\nWe chose to use Sobol\u2019 grid points (Sobol\u2019, 1967  ###reference_b33###), which offer even higher numerical precision compared to Latin hypercube samples.\nFigure 4  ###reference_### shows the point distribution of a uniform and of a Sobol\u2019 grid for comparison.\nWe found that using a low-discrepancy grid improved the numerical precision of the results.\n###figure_4### A major challenge in solving the model was to obtain stable estimates of the optimal emission mitigation rate .\nEstimating the optimal consumption rate  was straightforward, but estimating  required very precise estimates in the least-squares approximation of the conditional expectation.\nFigure 5  ###reference_### offers a partial explanation.\nIt illustrates a typical optimization surface when trying to find the optimal policies  in Equation (9  ###reference_###), showing a steep curvature for  and a much flatter surface for , indicating the need for precise numerical approximations and small tolerance values in the optimizer.\nWe see this issue as a consequence of the model setup.\nFor example, a low carbon intensity  for times after  leads to low emissions and mitigation costs, resulting in an almost negligible effect of the mitigation rate on the value .\nIn order to resolve this issue, very precise numerical approximations of conditional expectations based on a large number of well-spaced sample points as well as small tolerance values in the optimizer for  were required.\n###figure_5### Each point  in the state space can be optimized independently in Equation (9  ###reference_###).\nIn other words, when solving (9  ###reference_###) over a high-dimensional grid in state space, the individual optimization steps for each grid point can be executed in parallel.\nThis parallel optimization is implemented using Python\u2019s multiprocessing package over 64 cores, significantly reducing computation time and allowing for the usage of a reasonably large sample size without excessive computational costs.\nFigure 6  ###reference_### presents the evolution of the six most important variables over time if the optimal strategy is used, based on 500,000 independently simulated trajectories.\nThese six variables are the social cost of carbon , the global mean surface temperature , the carbon concentration in the atmosphere , the emission mitigation rate , total  emissions , and damages .\nThe panels include the median trajectory (bold solid line), expected trajectory (dash-dotted line), the 25 and 75 quantiles (dashed lines), the 10 and 90 quantiles (solid lines) as well as the range of sampling paths between the 1 and 99 quantiles (shaded area).\nWe can observe a significant amount of uncertainty in all variables.\nMost notably, a significant fraction of scenarios sees full mitigation (i.e. ) well before the year 2100 in the optimal case, though the median trajectory is a bit below the full mitigation in 2100.\nWe also observe that for temperature, the 1 quantile is approximately at 2.5\u2218C, while the 99 quantile is approximately at 4.5\u2218C.\nThe SCC is about US$200 in 2100 under the median trajectory, and between $150 and $300 for the 10% and 90% quantiles.\nFor all variables the median trajectory and deterministic DICE solution are virtually indistinguishable and very close to the expected trajectory.\n###figure_6### Figure 7  ###reference_### shows the first- and total-order Sobol\u2019 indices for various model outputs in relation to the 5 sources of uncertainty which we considered in the model.\nThe analyzed outputs are the social cost of carbon in 2020 (SCC), the mean surface temperature in the atmosphere in 2100 (TATM), the carbon concentration in the atmosphere in 2100 (MAT), output in 2100 (OUT), emissions in 2100 (EMI) as well as damages in 2100 (DAM).\nThe first-order Sobol\u2019 indices (left panel) illustrate the individual contribution of each input to the variance of the outputs, while the total-order Sobol\u2019 indices (right panel) capture the overall contribution, including interactions with other inputs.\nNote that first-order indices do not sum up to , as we have not taken into account higher order indices (second order, third order etc.).\nFrom Figure 7  ###reference_###, it is evident that output is predominantly impacted by total factor productivity, with both first-order and total-order indices close to 100, indicating a strong direct influence.\nIn contrast, the overall impact of the carbon intensity is negligible, with the indices being below 1 throughout.\nUncertainty in  could potentially be excluded to simplify the model without sacrificing accuracy.\nThe temperature-sensitivity and damage coefficients exhibit high indices across all remaining outputs, implying their large influence on the model outputs.\nBoth of these coefficients moreover show a significant difference between their first-order and total-order indices for emissions, suggesting substantial interaction effects with other inputs.\nNotably, the almost negligible first- and total-order indices for the carbon cycle coefficient with respect to emissions is contrasted by significant indices for damages, as well as atmospheric temperatures and carbon concentrations.\nFinally, we observe that uncertainty in the social cost of carbon in 2020 is largely due to temperature-sensitivity and damage coefficients.\nThis does not come as a surprise, as the uncertainty in  and  propagates through time and is therefore not very pronounced in the year 2020 (compared to, for instance, the year 2100).\nOverall, Figure 7  ###reference_### highlights that:\nProductivity has a strong influence on output, but neither on damages nor on temperatures.\nThe carbon intensity has a completely negligible impact on the model.\nThe temperature-sensitivity and damage coefficients have very strong impacts on the model.\n###figure_7### Figure 8  ###reference_### shows the evolution of first-order Sobol\u2019 indices for our main variables over time, up to the year 2150.\nIt highlights the fact that the impact of the uncertain variables on the outputs changes over time.\nMost notably, the changes appear not to follow a linear pattern, especially when looking at emissions.\nThere, the impact of total factor productivity  peaks around the year 2035, but declines rapidly afterwards.\nIn contrast, the impact of  on the social cost of carbon gradually rises from 0 in the year 2020, to around 25 in the year 2150.\nThis does not come as a surprise, as it highlights the effect of the large initial uncertainty about parameters such as the temperature-sensitivity and damage coefficients, which combines with a negligible initial uncertainty in total factor productivity that grows over time.\nAnother interesting effect that can be observed is that the total sum of all first-order indices declines for emissions from above 95 in the year 2020 to slightly below 40 in the year 2150.\nThis motivates the insight that the impact due to interactions between the uncertain variables grows over time.\n###figure_8### Table 2  ###reference_### shows the key statistics for the major variables.\nIn terms of the coefficient of variation (CV), we can observe the highest degree of uncertainty in emissions, followed by the social cost of carbon, damages, and output.\nMost importantly, the interquartile range (IQR) of 0.64C for temperature and 1.4 for damages highlights the importance of considering the notable variations in projections due to the presence of uncertainty.\nMoreover, we can re-confirm the presence of noticeable differences between the mean, median and best guess values for some variables, which is in line with the observations of Nordhaus (2018  ###reference_b26###).\nDifferences between the mean and median values hint at the presence of skewness in the distribution of the variables, which can also be visually confirmed from Figure 6  ###reference_###.\nFinally, differences between the best guess estimates and the mean and median values show that in some cases, the best guess provides a reasonable approximation of the complex dynamics, whereas in other cases it does not, which again highlights the importance of explicitly including stochastic dynamics into climate-economy models.\nSD, IQR and CV refer to standard deviation, interquartile range and coefficient of variation, respectively.\nBG refers to best guess, which is the value calculated along the expected trajectory, assuming that uncertainties are set to their respective means."

+    "abstract": "Freeform handwriting authentication verifies a person\u2019s identity from their writing style and habits in messy handwriting data. This technique has gained widespread attention in recent years as a valuable tool for various fields, e.g., fraud prevention and cultural heritage protection. However, it still remains a challenging task in reality due to three reasons: (i) severe damage, (ii) complex high-dimensional features, and (iii) lack of supervision. To address these issues, we propose SherlockNet, an energy-oriented two-branch contrastive self-supervised learning framework for robust and fast freeform handwriting authentication. It consists of four stages: (i) pre-processing: converting manuscripts into energy distributions using a novel plug-and-play energy-oriented operator to eliminate the influence of noise; (ii) generalized pre-training: learning general representation through two-branch momentum-based adaptive contrastive learning with the energy distributions, which handles the high-dimensional features and spatial dependencies of handwriting; (iii) personalized fine-tuning: calibrating the learned knowledge using a small amount of labeled data from downstream tasks; and (iv) practical application: identifying individual handwriting from scrambled, missing, or forged data efficiently and conveniently. Considering the practicality, we construct EN-HA, a novel dataset that simulates data forgery and severe damage in real applications. Finally, we conduct extensive experiments on six benchmark datasets including our EN-HA, and the results prove the robustness and efficiency of SherlockNet. We will release our code and dataset at https://github.com/WangJingyao07/SherlockNet.",

+            "text": "Handwriting refers to the act of writing using a specific instrument (e.g., a pen or pencil). Since each person\u2019s handwriting is unique, it is considered an important characteristic that is used in applications of various fields such as identity verification, e-security, and e-health [1  ###reference_b1###, 2  ###reference_b2###, 3  ###reference_b3###]. For instance, doctors utilize changes in handwriting as a diagnostic sign for Neurodegenerative Diseases (NDs) [4  ###reference_b4###], while forensic experts use handwriting clues to identify suspects [5  ###reference_b5###]. Therefore, handwriting authentication [6  ###reference_b6###, 7  ###reference_b7###, 8  ###reference_b8###, 9  ###reference_b9###] emerged as a result and became an interdisciplinary topic, aiming to verify or identify individuals using the unique features and patterns of handwriting. However, existing methods use a supervised manner for handwriting authentication that requires annotated handwriting data, which costs intensive [10  ###reference_b10###, 11  ###reference_b11###, 12  ###reference_b12###].\nImagine creating archives from written materials such as books, papers, or ancient bamboo slips. These archives contain large amounts of unlabeled handwriting data uploaded from various individuals in the real world, where the manual annotation process is complex and lengthy. Moreover, the real-world handwriting data is prone to noise and corruption [13  ###reference_b13###, 1  ###reference_b1###, 2  ###reference_b2###], so many supervised methods that work on labeled and clean data may fail [14  ###reference_b14###]. To address these challenges, self-supervised learning (SSL) has become popular in recent years [15  ###reference_b15###, 16  ###reference_b16###]. This paradigm aims to learn general representations without supervision and adapt well to downstream tasks.\nSeveral studies have delved into self-supervised learning to acquire representations of handwriting features, which can overcome the scarcity of supervision [17  ###reference_b17###, 18  ###reference_b18###, 19  ###reference_b19###]. Gidaris et al. [19  ###reference_b19###] encoded discrete visual concepts with spatially dense image descriptions. Lastilla et al. [17  ###reference_b17###] used unlabeled pure manuscripts to learn texture features. Chattopadhyay et al. [18  ###reference_b18###] leveraged SSL and metric learning for writer-independent OSV in a two-stage deep learning framework.\nHowever, in cases where the data is damaged or encounters significant disturbances, obtaining representations of the original data can result in significant ambiguities [20  ###reference_b20###, 21  ###reference_b21###].\nThis issue is particularly challenging in handwriting authentication, as it involves a vast number of damaged and fake samples in the real world, while the handwriting features are also complex.\nIn this work, we focus on a more challenging handwriting authentication topic: freeform handwriting authentication (see Figure 1  ###reference_###). It requires the model to perform accurate identity verification via freeform handwriting rather than just fixed content, facing huge challenges. Firstly, the handwriting data in real life may suffer from various damages [22  ###reference_b22###, 23  ###reference_b23###], such as scratches, stains, and folds from improper paper storage. Secondly, freeform handwriting means that the features become more complex and diverse. Unconstrained handwriting content also means that there may be multiple similar characters in the handwriting data, but with different strokes, colors, etc., which also makes handwriting authentication more difficult. In addition, due to the richness of the handwriting content, the annotation will face greater cost pressure [24  ###reference_b24###, 25  ###reference_b25###], making the supervised paradigm more unrealistic. Therefore, a superior model needs to achieve robust and fast freeform handwriting authentication under the conditions of (i) not restricting data quality; (ii) not constraining handwriting content; and (iii) not relying on supervision information.\nTo address these challenges, we propose SherlockNet, a novel energy-oriented two-branch contrastive self-supervised learning framework that focuses on the robustness, efficiency, and practicality in freeform handwriting authentication. It consists of four stages: pre-processing, generalized pre-training, personalized fine-tuning, and practical application. Specifically, in the pre-processing stage, we propose a plug-and-play energy operator that converts handwriting manuscripts into a series of energy distributions, effectively filtering out noise and preserving stroke information. The energy value indicates the probability that it belongs to handwriting features instead of noise. In the generalized pre-training stage, we propose a two-branch momentum-based adaptive contrastive learning framework to learn general representations from energy distributions, quickly extracting high-dimensional features of handwriting and mining spatial dependencies. In the personalized fine-tuning stage and practical application stage, we design convenient interfaces to make the users deploy the proposed SherlockNet in any downstream scenario, which only relies on a few samples with a few steps.\nOur contributions can be summarized as follows:\nWe explore a challenging topic: freeform handwriting authentication, which faces three key issues in real-world applications: (i) severe damage, (ii) complex high-dimensional features, and (iii) lack of supervision.\nWe propose SherlockNet, an energy-oriented two-branch contrastive self-supervised learning framework for robust and fast freeform handwriting authentication.\nWe present EN-HA, a freeform handwriting authentication dataset that mimics real-world scenarios, such as data forgery and severe damage in handwriting data.\nExtensive experiments are conducted on six benchmark datasets, and the results demonstrate the superior robustness and efficiency of the proposed SherlockNet.\n###figure_1###"

Handwriting has gained increasing attention and found widespread applications in various fields such as forensic identification [5  ###reference_b5###], medical diagnosis [4  ###reference_b4###], information security [12  ###reference_b12###], and document forgery detection [27  ###reference_b27###]. However, due to its complexity and large variability, handwriting authentication remains a challenging task [7  ###reference_b7###, 8  ###reference_b8###].\nTo cope with the growing demand for handling big data, traditional manual inspection of handwriting is inefficient [28  ###reference_b28###, 29  ###reference_b29###]. As a result, research has shifted towards machine-based methods [30  ###reference_b30###, 31  ###reference_b31###, 32  ###reference_b32###] to bridge the gap between current needs and actual applications. Davis et al. [33  ###reference_b33###] developed a generator network trained with GAN and autoencoder techniques to learn handwriting style. Zhang et al. [34  ###reference_b34###] proposed an end-to-end framework for online text-independent writer identification that leverages a recurrent neural network (RNN). Mohammad et al. [7  ###reference_b7###] proposed a new Arabic online/offline handwriting dataset and using an SVM-based method for writer authentication. Begum et al. [8  ###reference_b8###] concentrated on real-time and context-free handwriting data analysis for robust user authentication systems using digital pen-tablet sensor data. Although these methods have been successful in enhancing the efficiency of handwriting authentication, they rely on a large amount of labeled and pure data, while having high requirements on the writing content, for example, it can only be signature. Unfortunately, in reality, it is difficult to meet the data requirements of these methods (see Figures 1  ###reference_### and 2  ###reference_###).\nIn this study, considering practicality in the real world, we focus on and explore a more challenging topic for the first time, i.e., freeform handwriting authentication. It is more challenging in that: (i) it does not rely on supervised information; (ii) it does not restrict the handwriting content; and (iii) it does not require pure data, which makes this work novel and practical, and can be applied to real-world scenarios."

+            "text": "Self-supervised learning (SSL) plays a crucial role in advancing technology during the big data era, offering robust representation by learning knowledge from pretext tasks without annotations. Notably, SSL methods can be broadly divided into two types: contrastive learning and generative learning.\nContrastive learning performs learning by applying various data augmentations and encouraging the augmented views of the same sample closer while pushing apart views from other samples, and then using the learned knowledge to solve new tasks [35  ###reference_b35###]. This technique can significantly enhance performance in various visual tasks [36  ###reference_b36###, 37  ###reference_b37###], and its typical algorithms include SimCLR [38  ###reference_b38###], MoCo [39  ###reference_b39###], BYOL [40  ###reference_b40###] etc. For handwriting data, Lin et al. [41  ###reference_b41###] proposed using contrastive learning to learn semantic-invariant features between printed and handwriting characters. Viana et al. [42  ###reference_b42###] explained how deep contrastive learning can lead to an improved dissimilarity space for learning representations from handwriting signatures. Zhang et al. [43  ###reference_b43###] extended Moco [39  ###reference_b39###] to show the significant advantages of self-supervision in dealing with complex handwriting features. Although the existing methods have demonstrated the ability to extract complex features, they rely on a large amount of pure handwriting data with consistent content, making it difficult to apply well and achieve free-form handwriting authentication in the real world.\nGenerative learning involves the reconstruction of inputs from original or damaged inputs, and the creation of representation distributions at a point-wise level, such as pixels in images and nodes in graphs. Classic methods include auto-regressive (AR) models [44  ###reference_b44###, 45  ###reference_b45###], flow-based models [46  ###reference_b46###, 47  ###reference_b47###], auto-encoding (AE) models [48  ###reference_b48###, 49  ###reference_b49###], and hybrid generative models [50  ###reference_b50###, 51  ###reference_b51###]. For handwriting data, considering the properties of this paradigm, generative learning can work in terms of data augmentation for auxiliary training when data is insufficient [52  ###reference_b52###, 53  ###reference_b53###, 54  ###reference_b54###]. He et al. [55  ###reference_b55###] introduced masked autoencoders (MAE) as a scalable self-supervised learning approach for computer vision aimed at reconstructing missing patches in images. However, although generative learning can mitigate the negative effects of lacking labels, it is not suitable for handwriting authentication whose primary focus is learning complex features without supervision."

Common text image defects that affect handwriting quality include scratches, damage, stains, and folds (as shown in Figure 2  ###reference_###). While manuscripts of famous authors are valuable objects, they still have image defects that can impact the visual quality. For instance, connecting strokes under stain masking can be mistakenly judged as high-density handwriting dots.\nTo improve the visual quality of manuscripts, we design a plug-and-play energy-oriented operator, denoted as . The operator  converts handwriting manuscripts into a series of energy distributions, where  denotes the two-dimensional fast Fourier transform,  is the regularization term used to maintain the smoothness,  is the data term consisting of similarity constraint. The energy value indicates the probability that it belongs to handwriting features instead of noise. Therefore, filtering out the low-energy pixels can address disturbances caused by handwriting conditions and text preservation in daily life. Figure 2  ###reference_### (b) shows some samples of authentic works of famous authors collected in our study.\nWe start by obtaining the input handwriting data , which may contains various noise.

Specifically, we first assign the initial weights on each patch , i.e., each weight of  patches is set to . Subsequently, we adjust the weights based on the calculated energy distribution, i.e., normalize weights after assigning values via the score of energy. Then, we use a weight boost of  to top- patches for  steps based on the current gradient of the model  in every  iteration. The gradient calculation is as described in Eq.5  ###reference_###. Note that although the augmented samples mostly preserve the same properties [56  ###reference_b56###], the key patches may vary. Moreover, setting a consistent weight matrix for homologous augmented samples in a batch can improve computational efficiency, but it may also impair performance. Therefore, in the next step, we remove patches with changes smaller than  of the mean change every  times until reaching the upper limit of iterations  or the threshold for eliminating patches. After combining the weights with the original weights and then normalizing, we obtain  with more accurate weights.\nIn the second branch, we just assign the same initial weights to each patch of the augmented images, and demote it as .\nNext, we flatten and put all patches, i.e.,  and  to the same feature extractor , obtaining the representations of  which are denoted as , and the representations of  which are denoted as .

This breakthrough is accomplished without annotated data and observed in almost every dataset, especially in EN-HA, which simulates real-life data forgery and corruption. This achievement underscores the effectiveness and robustness of SherlockNet.\nThrough further analysis, we obtain three observations: (i) From features: deep learning features perform better than manual features, e.g., the results of FragNet are better than NN-LBP. Learning based on automatic features, e.g., GR-RNN, is more effective than local texture features, e.g., CoHinge, while structural features, e.g., COLD, reduce the recognition effect; (ii) From datasets: image forgery hurts most models, resulting in the Top 1 result of baseline models on EN-HA being far lower than that of SherlockNet, which specifically deals with fake samples. The narrowing of the gap in the Top 5 results indicates that balancing samples and finding key areas are key factors for improving performance; and (iii) From the learning paradigm: our SherlockNet achieves significant progress in SSL frameworks, indicating that the complexity and specificity of handwriting features require specific settings to learn."

To explore the learning process in depth, we used t-SNE to visualize the feature representations of EN-HA. We visualize three scenarios: 100% ideal data, 70% ideal data + 30% forged data, and data with 30% noise, respectively. Figure 11  ###reference_### shows the feature distribution of the three scenarios. From the results, we can observe that: (i) handwriting data have diverse features, and some features are difficult to distinguish; (ii) in redundant data, noise shows intra-class aggregation, but there is no significant difference from real features, which may cause some models to mistake noise as real features and learn from them; and (iii) the feature distribution of forged data is different from that of real data, but the difference is small and hard to be detected.

However, despite the above breakthroughs, freeform handwriting authentication remains an open area for research, which we aim to explore further in the future. Firstly, changes in handwriting may occur due to various reasons, i.e., mood, mental state, age, etc. Additionally, different writing instruments can lead to different handwriting styles. Therefore, we plan to introduce the temporal dimension into freeform handwriting authentication, rather than limiting it to the identification of individual style fixations. Moreover, supervised methods for freeform handwriting authentication are task-specific due to the different writing properties of different languages, e.g., the cursive form of Arabic. SherlockNet is suitable for such complex and challenging changes, but the lack of evaluation standards and more benchmark datasets hinders its development. We believe this work can provide a solid foundation for freeform handwriting authentication, and we will further expand our research in the future."

It addresses the three key challenges in freeform handwriting authentication, i.e., (i) severe damage, (ii) complex high-dimensional features, and (iii) lack of supervision. SherlockNet consists of four stages, i.e., pre-processing, generalized pre-training, personalized fine-tuning, and practical application. Specifically, in the pre-processing stage, we develop a plug-and-play energy-oriented operator to calculate the energy distribution in each handwriting manuscript, eliminating the impact of data corruption and forgery such as scratches and stains. In the pre-training stage, we propose a two-branch momentum-based adaptive contrastive learning framework to learn general representations from energy distributions, enabling swift extraction of complex high-dimensional features while also identifying spatial correlations. Moving into the personalized fine-tuning and practical application stages, we develop user-friendly interfaces that allow individuals to easily deploy SherlockNet in various real-world applications. This deployment merely necessitates a few samples with a few steps, facilitating effortless freeform handwriting authentication.\nMoreover, to simulate real-world scenarios, we construct a new dataset called EN-HA, which contains damaged and forged data.\nExtensive experiments demonstrate that SherlockNet outperforms existing baselines, highlighting its effectiveness and robustness for freeform handwriting authentication."

+    "abstract": "Traumatic brain injury (TBI) can cause a range of cognitive and communication challenges that negatively affect social participation in both face-to-face interactions and computer-mediated communication. In particular, individuals with TBI report barriers that limit access to participation on social media platforms. To improve access to and use of social media for users with TBI, we introduce the Social Media Accessibility and Rehabilitation Toolkit (SMART-TBI). The toolkit includes five aids (Writing Aid, Interpretation Aid, Filter Mode, Focus Mode, and Facebook Customization) designed to address the cognitive and communicative needs of individuals with TBI. We asked eight users with moderate-severe TBI and five TBI rehabilitation experts to evaluate each aid. Our findings revealed potential benefits of aids and areas for improvement, including the need for psychological safety, privacy control, and balancing business and accessibility needs; and overall mixed reactions among the participants to AI-based aids.",

+            "section_name": "1. Introduction",
+            "text": "Traumatic brain injury (TBI) is a significant public health concern, affecting approximately 69 million individuals every year worldwide (Dewan et al., 2018  ###reference_b31###; Wongchareon et al., 2020  ###reference_b67###). TBI refers to damage caused to the brain as a result of an external force, and typically occurs through falls, car accidents, sports injuries, or assaults (for Disease Control and Prevention, 2022  ###reference_b39###). TBI can vary in severity from mild to severe, limiting an individual\u2019s functioning and leading to chronic cognitive, physical, and emotional impairments. Among these, cognitive and communication challenges are particularly debilitating, often interfering with an individual\u2019s ability to engage in everyday activities and social interactions (MacDonald, 2017  ###reference_b50###).\nAdults with TBI often report social isolation (Mukherjee et al., 2003  ###reference_b54###) and friendship loss (Salas et al., 2018  ###reference_b56###) after injury. They may experience physical and cognitive limitations that make in-person social interactions challenging (Hoofien et al., 2001  ###reference_b43###; Turkstra et al., 2008  ###reference_b65###; Hu et al., 2023  ###reference_b45###). Thus, individuals with TBI could especially benefit from the social connection opportunities provided by computer-based communication technologies. Computer-mediated communication (CMC) is the use of social media, texting, or email to communicate with others, and is ubiquitous in today\u2019s society (Kaplan and Haenlein, 2010  ###reference_b48###). Social media platforms have revolutionized how people establish social connections, collaborate, participate in social events, and obtain information in daily life (Ellison and Vitak, 2015  ###reference_b35###; Gil de Z\u00fa\u00f1iga et al., 2012  ###reference_b40###; Herring, 2002  ###reference_b42###; Hu et al., 2022  ###reference_b46###). Previous literature showed that social media use can enhance users\u2019 social capital (Ellison and Vitak, 2015  ###reference_b35###), contribute to friendship maintenance (Sprecher et al., 2019  ###reference_b59###), and stimulate social sharing (Choi and Toma, 2014  ###reference_b24###, 2021  ###reference_b25###), all of which could benefit adults with TBI. There is evidence that people with TBI use social media platforms such as Facebook and Twitter as frequently as those without a brain injury (Brunner et al., 2020  ###reference_b15###) and may even prefer these online interactions to face-to-face communication (Toma et al., 2024  ###reference_b63###). Yet, the benefits of social media may not be fully accessible to these individuals due to their cognitive and communication impairments (Toma et al., 2024  ###reference_b63###). These impairments can include cognitive overload, which makes processing information more challenging, and difficulties interpreting social cues, which are crucial for effective online communication (Brunner et al., 2015  ###reference_b13###, 2020  ###reference_b15###; Tsaousides et al., 2011  ###reference_b64###; Feuston et al., 2017  ###reference_b36###; Brunner et al., 2019a  ###reference_b16###). While prior research in this area has provided critical information about social media usage among individuals with TBI (Brunner et al., 2015  ###reference_b13###, 2019a  ###reference_b16###, 2021  ###reference_b19###; Morrow et al., 2021  ###reference_b53###) and identified their challenges and needs (Brunner et al., 2022  ###reference_b18###, 2023  ###reference_b17###; Ahmadi et al., 2022  ###reference_b3###), there is limited research on how to overcome those challenges and make social media accessible for individuals with TBI\n(Brunner et al., 2015  ###reference_b13###; Shpigelman and Gill, 2014  ###reference_b57###).\nTo address this gap, we designed and built SMART-TBI (Social Media Accessibility and Rehabilitation Toolkit for Traumatic Brain Injury), a suite of digital accessibility aids that aim to support adults with TBI-related cognitive and communication challenges so they can successfully use social media platforms. Our choice of accessibility aids was based on our prior collaborative research with adults with TBI, in which users envisioned social media accessibility supports (Ahmadi et al., 2022  ###reference_b3###; Lim et al., 2023  ###reference_b49###; Zhao et al., 2022  ###reference_b69###). SMART-TBI consists of five types of aids: Writing Aid, Interpretation Aid, Filter Mode, Focus Mode, and Facebook Customization. The toolkit was designed using Facebook because it was the most actively used social media platform among individuals with TBI (Morrow et al., 2021  ###reference_b53###), and can be easily integrated into a user\u2019s current social media practices.\nWe evaluated each aid in the toolkit with both users with TBI and rehabilitation experts specializing in TBI. During the user evaluation, we asked eight Facebook users with TBI to perform a series of tasks on the Facebook platform, both with and without using the aids. They also completed questionnaires to assess the usability and intention to use each aid and participated in interviews to provide feedback on potential improvements. Subsequently, we presented the SMART-TBI to five TBI experts and solicited their feedback on each aid with a questionnaire derived from the W3C Cognitive Accessibility Guidelines, which outline requirements and recommendations for making web content more accessible to people with cognitive and learning disabilities (Consortium, 2022  ###reference_b27###).\nOur findings revealed the potential benefits of the toolkit in addressing diverse cognitive and communication challenges that individuals with TBI may encounter on social media platforms, while also indicating areas for improvement for each aid. In particular, the results highlighted SMART-TBI\u2019s potential to enhance social communications across various aspects, including self-presentation, organized use of social media, and distraction reduction. The results also shed light on design implications for future accessible social media design, emphasizing the need to promote psychological safety and privacy control, balance business profits with accessibility needs, and address mixed reactions to AI-based aids for toolkit adoption among individuals with diverse TBI needs.\nOur contributions are as follows:\nToolkit design and development: We designed and implemented the SMART-TBI that could be easily integrated into Facebook platforms.\nInsights for accessibility toolkit for individuals with TBI: We evaluated the SMART-TBI with both users with TBI and TBI rehabilitation experts. Our findings highlighted both positive feedback and areas of improvement for each aid, offering design insights for the development and implementation of future accessible social media platforms for individuals with TBI."

Cognitive challenges from TBI may include difficulties in reasoning, attention and concentration, problem-solving skills, memory, and executive functions (Sohlberg et al., 2022  ###reference_b58###). In particular, impairments in executive functions, such as inhibitory control (i.e., the ability to manage one\u2019s attention, thoughts, and behaviors to perform a necessary task) and working memory (i.e., holding information in mind and mentally manipulating it), can result in diminished focus and attention (Diamond, 2013  ###reference_b32###).\nIn particular, cognitive-communication difficulties refer to challenges in communication related to language comprehension and production (MacDonald, 2017  ###reference_b50###). Individuals with cognitive-communication challenges may struggle with speaking, word finding, understanding language, or expressing their thoughts effectively. For example, an individual with cognitive-communication difficulty might miss key details in written correspondences or repeat information (Dinnes et al., 2018  ###reference_b33###). These difficulties can lead to frustration and social isolation, making it harder for individuals to engage in meaningful interactions with others (Togher et al., 2023  ###reference_b61###).\nSocial communication, which relies on social cognition and language skills to engage in meaningful conversations across various social settings, is often impaired in individuals with TBI (of Neurologic Communication Disorders Traumatic Brain Injury Writing Committee et al., 2020  ###reference_b55###; Struchen et al., 2011  ###reference_b60###; Finch et al., 2016  ###reference_b37###). Social cognition is crucial for interpreting social cues and communicating effectively (Sohlberg et al., 2022  ###reference_b58###; Byom and Turkstra, 2012  ###reference_b20###) involving recognizing emotions, predicting behaviors, and understanding others\u2019 intentions, encompassing components like the theory of mind and empathy (Byom and Turkstra, 2012  ###reference_b20###).\nAdditionally, many individuals with TBI struggle with behavioral self-regulation, including emotional modulation and impulse control (McDonald and Genova, 2021  ###reference_b52###). These difficulties together could lead to reduced social participation and lower life satisfaction (Dahlberg et al., 2006  ###reference_b28###)."

+            "text": "Individuals with traumatic brain injuries could benefit from social media platforms in mitigating social isolation. For instance, social media may lessen the cognitive, communication, and social demands of face-to-face interactions by providing more time to process information, formulate responses, and engage at their own pace without the immediate pressure of real-time conversation (Brunner et al., 2019a  ###reference_b16###). Social media can also help individuals with TBI connect with others who have similar lived experiences and exchange social support (Morrow et al., 2021  ###reference_b53###; Brunner et al., 2019a  ###reference_b16###).\nPromisingly, prior research showed that individuals with TBI maintain social media accounts at similar rates as healthy individuals (Tsaousides et al., 2011  ###reference_b64###; Morrow et al., 2021  ###reference_b53###) and are highly interested in using social media for various purposes, including social connection (Brunner et al., 2019a  ###reference_b16###, b  ###reference_b14###; Morrow et al., 2021  ###reference_b53###).\nNevertheless, individuals with TBI may also encounter various challenges when using social media due to their cognitive (e.g., attention, memory) and cognitive-communication (e.g., processing written information) impairments. One significant challenge is navigating the varied interfaces and features of social media platforms (Lim et al., 2023  ###reference_b49###). The complexity of these interfaces can be overwhelming for individuals with TBI, and the abundance of information can be difficult to process (Brunner et al., 2019b  ###reference_b14###). Due to changes in cognitive function, individuals with TBI may experience difficulties in expressing themselves online, leading to reduced confidence in communication (Lim et al., 2023  ###reference_b49###; Brunner et al., 2019b  ###reference_b14###). Additionally, individuals with TBI may experience a decreased ability to understand others\u2019 sentences or to read texts, which can further compound their social media challenges (Flynn et al., 2019  ###reference_b38###; Lim et al., 2023  ###reference_b49###). For example, an individual with TBI with impaired social cognition may misinterpret a friend\u2019s sad post and comment with laughing emojis, failing to recognize the emotional context of the message (Clough et al., 2023  ###reference_b26###). These challenges highlight the importance of providing sufficient resources to support individuals with TBI in navigating and taking advantage of social media platforms."

+            "text": "Although Internet usage is common among individuals with TBI, there are still notable technological and access barriers in comparison to the general population (Baker-Sparr et al., 2018  ###reference_b6###), limiting their ability to fully take advantage of the social benefits of social media platforms (Morrow et al., 2021  ###reference_b53###). Therefore, accessibility support for social media is crucial for individuals with TBI to access and utilize these platforms effectively. To improve social media accessibility for people with traumatic brain injuries, a recent study by Lim et al. (2023  ###reference_b49###) adopted a participatory design approach to gather insights on technological tools that could improve the social media experience of users with TBI. Brunner and colleagues Brunner et al. (2023  ###reference_b17###) developed an online training course as part of the \u201cSocial Brain Toolkit\u201d to support people with acquired brain injury to learn about social media use. Furthermore, Zhao et al. (2022  ###reference_b69###) proposed the design of four social media support aids to address challenges of sensory overload, memory loss, social communication, and lack of confidence in using social media faced by users with TBI.\nResearch on individuals with cognitive and physical disabilities has revealed benefits and challenges of social media use similar to those experienced by people with TBI (Caton and Chapman, 2016  ###reference_b22###; Bassey et al., 2023  ###reference_b7###; Baumgartner et al., 2023  ###reference_b8###). Common challenges include cognitive challenges, limited digital literacy, communication barriers, and the complexity of online interactions (Caton and Chapman, 2016  ###reference_b22###; Alfredsson \u00c5gren et al., 2020  ###reference_b4###). To address accessibility issues that stem from these challenges, researchers have developed solutions such as \u201cEndeavor Connect,\u201d a cognitively accessible Facebook interface designed for young adults with intellectual disabilities (Davies et al., 2015  ###reference_b30###).\nAs such, this work builds on a rich body of previous research on social media accessibility support. We designed and implemented SMART-TBI as web browser extensions that work on the web version of Facebook, providing users with essential support for social media use in their everyday lives. The SMART-TBI can be easily installed, offering a practical solution to the challenges faced by individuals with TBI when using social media platforms. While currently focused on Facebook, our approach has the potential to extend across various social media platforms."

+            "text": "###figure_1### This figure illustrates the design process for the SMART-TBI, organized into three columns. The first column identifies social media challenges faced by individuals with Traumatic Brain Injury (TBI). The second column outlines the design goals developed to address these challenges. The third column presents five specific design aids that were created based on these goals, aiming to facilitate improved usability and engagement for users with TBI\nWe designed and built a social media toolkit to meet the accessibility needs and challenges of TBI users that had been identified in prior literature (Lim et al., 2023  ###reference_b49###; Zhao et al., 2022  ###reference_b69###; Brunner et al., 2023  ###reference_b17###; Davies et al., 2015  ###reference_b30###). We categorized the major challenges in social media use by individuals with TBI into two types: communication challenges and cognitive challenges.\nCommunication challenges included challenges related to impairments in social cognition, language comprehension, and language production. These challenges might lead users with TBI to misinterpret the tone or intent of a written post and take sarcasm or humor literally, write messages that readers would consider inappropriate to the context, or overshare personal information. Cognitive challenges in using social media are mostly related to impairments in executive functions, leading to challenges in maintaining focus, planning, and managing information overload. As a result, users with TBI might struggle to organize their thoughts coherently in a post, leading to fragmented or confusing content. Similarly, challenges with planning could lead to impulsive posting without considering the consequences or the appropriateness of the content for a public platform. Information overload could have users with TBI become overwhelmed by details and irrelevant information surrounding posts\u2014including text in sidebars\u2014and give up on reading or posting content.\nIn addressing these challenges, we identified several design goals that we realized in five types of aids as shown in Figure 2  ###reference_###. In particular, to address the communication challenges, we designed aids to help users comprehend social media content more accurately, enhance message construction, and minimize the creation of inappropriate content (e.g., offensive posts) (Lim et al., 2023  ###reference_b49###). We identified three design goals: (1) minimizing inappropriate language use; (2) supporting sentiment comprehension; and (3) improving grammar and spelling. To address cognitive challenges, aids must assist users with TBI in managing information, facilitate navigation through social media features, and minimize distractions while viewing content (Lim et al., 2023  ###reference_b49###). Accordingly, we established four design goals to address these cognitive challenges: (4) simplifying social media features; (5) personalizing social media features; (6) simplifying newsfeed content, and (7) and personalizing newsfeed content.\nBased on these design goals, we developed five accessibility aids to assist individuals with TBI in using social media (Figure 3  ###reference_###). Two aids were designed to provide communication support: (1) the Writing Aid, which enabled users to perform four writing checks before posting on their Facebook feed, and (2) the Interpretation Aid, which helped users interpret social cues (focusing on sentiment and emotion) within Facebook posts. Three aids were designed to provide cognitive support: (3) the Filter Mode, which allowed users to customize their Facebook feed; (4) the Focus Mode, which decluttered the Facebook news feed; and (5) the Facebook Customization, designed to customize the Facebook layout. All five aids were implemented as Google Chrome extensions for use within the web version of Facebook. We detail the design and implementation of each aid in the following section. Demonstrations and implementation of each aid are provided in the GitHub repository111https://smart-tbi.github.io/index.html  ###reference_###\nhttps://github.com/smart-tbi/smart-tbi  ###reference_###."

In particular, the Writing Aid performed four types of writing checks, including (1) potential spelling or grammatical errors in their post; (2) potential toxicity within the language of the post; (3) the tone (e.g., positive, neutral, negative) and emotion type (e.g., happy, sad) of the post; and (4) the privacy settings of the post (e.g., public versus private).\nThe detection of grammar errors, sentiment, and toxicity in the posts was achieved through external application programming interfaces (APIs) (i.e., Textgears API111https://textgears.com/ for grammar check, IBM Watson NLP API222https://www.ibm.com/products/natural-language-understanding for sentiment and emotion detection, and perspective API for toxicity detection333https://perspectiveapi.com/).\nThe Writing Aid interface starts to appear on the screen after users begin writing a post. Once they write a draft of their post, the aid guides users through the four writing checks, allowing them to recheck each step after any updates are made. After completing all four checks, the aid provides a full summary, including all writing-check results, followed by an opportunity for the user to review the changes to their post prior to posting the final draft. The accuracy of sentiment and emotion analysis was reported between 73%\u201385% (Abu-Salih et al., 2023  ###reference_b2###; Carvalho et al., 2019  ###reference_b21###), and the AUC-ROC scores (Bradley, 1997  ###reference_b9###) of the toxicity detection was reported between 0.97\u20130.99.444https://developers.perspectiveapi.com/s/about-the-api-model-cards\nWhile the spell-checking functionality in our Writing Aid powered by the Textgears API may not differ fundamentally from default browser spellcheckers, our goal was to provide a centralized, step-by-step approach to address the various considerations involved in writing posts. For individuals with TBI, navigating multiple aspects of writing, such as basic spell checking, toxicity and tone management, and privacy settings, can be overwhelming and prone to errors when distributed across different tools. Therefore, we consolidated these considerations into a single, guided process within the Writing Aid."

Additionally, the alt texts of post images in the posts were extracted and shown to display the image details.\nWhile individuals with TBI are scrolling through their Facebook feed with this aid, an \u201cAnalyze\u201d button appears alongside every post. If the user clicks the button, the Interpretation Aid interface appears beside the post that summarizes the sentiment analysis of the post, including the tone and emotion type.

While using Facebook for ten minutes, an experimenter asked the participant questions to encourage reflection on their Facebook experience (e.g., \u201cCan you tell me your favorite part of Facebook\u201d).\nWithin stage two, participants were asked to perform the following three tasks on Facebook without using any aids.\nInterpretation Task: The first task involved interpreting three posts on the Facebook account, specifically created for this study (Appendix A.2  ###reference_###). After participants viewed each post, we asked open-ended questions to participants, such as \u201cWhat emotions do you think of in this post?\u201d They were also asked to rate the sentiment of each post on a five-point Likert scale (i.e., Very Negative, Negative, Neutral, Positive, and Very Positive). Following completion of these tasks, participants rated their confidence in their judgments and ease in performing these interpretation tasks by answering the interpretation task questions in Table 3  ###reference_###.\nFocus Task: Participants were instructed to browse and scroll through their Facebook newsfeed for two minutes. Following that, the experimenter prompted them to recall and describe the posts they just viewed, using a few sentences (e.g., \u201cCan you recall the posts you just browsed\u201d). Participants were then asked to provide feedback on the task by answering Focus task questions in Table 3  ###reference_###.\nFilter Task: In the third task, participants were asked to browse their Facebook newsfeed and inform the experimenter whenever they found an interesting post. Then, they were asked to refresh the page again and find a post from a friend 222Based on our observations, Facebook always prioritizes unseen content at the top. Thus, we asked participants to refresh the newsfeed page before and between tasks.. Following this, participants were asked to provide feedback on the task by answering Filter task questions in Table 3  ###reference_###.\nAfter completing the three tasks described above, the participants were asked to identify their top five most frequently used menus in the left panel of the Facebook web browser. The total duration of stage 2 ranged from 20 to 30 minutes for each participant.\nDuring stage 3, participants first repeated the same Interpretation Task, Focus Task, and Filter Task as in stage 2 using the aids: Interpretation Mode, Focus Mode, and Filter Mode, respectively. Before starting each task, the experimenter introduced the aid that would be used for the task and demonstrated how to use it step by step. Then the user had a trial session using the aid until they felt comfortable and familiar with the tool. After the participant finished the trial session, the experimenter instructed the participant to proceed with the tasks. Additionally, participants completed a Writing Task where the experimenter asked the participant to write three hypothetical posts on provided topics (Appendix A.1  ###reference_###). Additionally, they were asked to use the Writing Aid to improve their writing. After writing each post, the participant was asked a series of questions about their experience in the writing task (see Table 5  ###reference_###). Lastly, participants worked on the Facebook Customization Task that asked them to customize the layout of their Facebook main page using the Facebook Customization aid.\nAfter each task, participants evaluated each aid with the System Usability Scale (SUS) (Brooke et al., 1996  ###reference_b12###) and answered open-ended questions (e.g., \u201cHow was your experience with the tool?\u201d) to reflect on their impressions on each aid. After completing all five tasks in stage 3, the participants were instructed to rank the five aids in order of most helpful to least helpful. The total duration of stage 3 ranged from 45 to 60 minutes.\nStage 4 consisted of participants answering demographic questions (e.g., gender, age, race, education, and employment status) and questions related to their TBI (e.g., time since injury, cause of injury, and challenges since injury). This stage ended with surveying participants about their usual Facebook usage (e.g., usage amount, reasons for usage, changes to social media usage after their TBI).

To accommodate the cognitive challenges associated with participants\u2019 TBI, we employed a simplified three-point Likert scale (Disagree, Neutral, and Agree) for each statement in the SUS.\nWe developed questionnaires with a three-point Likert scale (1\u20133; 1 = Disagree, 2 = Neutral, 3 = Agree) for each aid (Table 3  ###reference_###). For the writing task, we utilized a seven-item questionnaire and derived two scales that measured the perceived quality of the written post (items 1, 7; Cronbach\u2019s ) and how well the message is received by other people (items 3, 5; Cronbach\u2019s ). For the Interpretation task, we used a three-item questionnaire to evaluate the confidence level, the clarity of the post, and the ease of the task. For the Focus task and Filter task, we developed a five-item questionnaire and derived two scales that measured the perceived ease of the task (items 1, 2, 5; Cronbach\u2019s ) and success of the task (items 3, 4; Cronbach\u2019s ). We hypothesized that the user would perceive the writing task to have higher quality using the Writing aid than without the aid; the user would have a higher level of confidence in the Interpretation task using the Interpretation aid than without the aid; the user would perceive the task to be easier and more successful using the Focus Mode and Filter Mode than without the aids.\nWe also collected and analyzed task performance data for the Focus Mode and Filter Mode aids, and we evaluated their effectiveness pre- and post-use of the aids. Specifically, we collected the number of posts recalled by the participant after viewing the newsfeed for two minutes before and after applying Focus Mode to the newsfeed. We hypothesized that the user would recall more posts using the Focus Mode than without the aid. We also counted the time the user found an interesting post and the time to locate a post from their friend before and after they applied the Filter Mode to customize the feed. We hypothesized that the user would spend less time locating the posts using the Filter Mode than without the aid.\nW3C\u2019s Cognitive Accessibility Guidelines contain eight objectives and each objective has a list of design requirements necessary to meet the objective. We customized the W3C questionnaires for each aid and removed irrelevant items. For example, \u201cObjective 8: Support adaptation and personalization.\u201d is not applied to the Writing Aid and the Interpretation Aid because these two aids were designed to provide communication support rather than improve the personalization of social media use. Therefore, Objective 8 was removed when participants evaluated these two aids.\nIn analyzing the expert questionnaires for the guidelines for Facebook in general, as well as for the five aids, we calculated the percentage of design patterns met for each objective. For example, to determine if the \u201cFocus mode\u201d met the objective \u201cHelp users focus,\u201d we scored it as 50% when one participant answered \u201cYes\u201d to two design patterns out of four. We also transcribed and open-coded the comments that expert participants provided while using each of our five aids.\nWe recorded the full study sessions with users with TBI. Audio files were first transcribed with an automatic transcription tool666https://otter.ai, and then one researcher from the team verified the transcriptions and corrected errors. This researcher further segmented the transcriptions according to the study procedures, differentiating between responses related to questionnaire items and answers given during the experimenter\u2019s interview questions.\nWe analyzed the transcriptions using thematic analysis (Braun and Clarke, 2022  ###reference_b11###, 2006  ###reference_b10###). Two coders first independently open-coded three data samples (more than 10% of the data) at the sentence level and then merged their codes to develop the initial codebook.

The final codebook included categories detailing participants\u2019 social media usage patterns, the challenges they faced using social media due to TBI, and their feedback on each aid. Given we have specific goals to understand the usefulness and usability for each aid in the toolkit, we follow the deductive approach (Braun and Clarke, 2022  ###reference_b11###, 2006  ###reference_b10###) to generate themes focusing on particular aspects, i.e., the perceived usefulness, usability challenges, and suggested new functions for each aid.\nWe had both online and in-person study sessions with TBI expert participants.

This section highlights the findings from the qualitative feedback followed by key design insights from TBI users and experts respectively. For each aid, we first present participants\u2019 overall attitudes, drawing on their responses to the interview question, \u201cHow do you like the aid?\u201d, and their ratings from the SUS statement, \u201cI think I would like to use the system frequently.\u201d This is followed by detailed comments from participants about their experiences focusing on the perceived usefulness of the aid, usability challenges, and suggested new features. The findings are summarized in Table 7  ###reference_###.\nDuring the study, participants used the Writing Aid for spelling and grammar checks for the writing tasks.\nAll participants found the aid useful, and four out of eight participants agreed that they would like to use the aid frequently (P1, 5, 7, 8). The aid was reported to support message construction and spell checks (P6, P8), facilitate sentiment analysis (P5, P7), and enhance privacy settings (P7). One participant noted it provided \u201ca different perspective on how others might view it\u201d (P6), thus indicating that the design objectives of the Writing Aid could be attained to some degree. Additionally, two participants emphasized the need for self-presentation in using social media (P1, P5) and thought that the aid could \u201chelp you change your story\u201d (P5) and confirm that \u201cIs this character (myself) polished enough to be on someone\u2019s network\u201d (P1).\nMeanwhile, TBI user participants identified two major usability challenges: inaccurate grammar and sentiment analysis of the content (P3, P4, P7) and the inconvenience of repeating writing checks after modifying posts (P2, P7, P8). For example, P4 experienced inaccurate grammar suggestions that incorrectly flagged slang she wrote in her posts, such as \u201cgonna\u201d and \u201cIma.\u201d P7 suggested a potential design improvement, proposing a single button to restart the sequence of checks after making edits. He stated, \u201cI would add a button at the end to go back to the start\u2026in case you want to redo something and maybe recheck a specific section before you post it.\u201d (P7). Additionally, P2 desired more learning support, stating that, \u201cit was frustrating at first\u201d (P2), and wanted the aid to provide more \u201cspecific\u201d instructions for improving the content.\nFour out of five expert participants (EP1\u20133, EP5) provided positive feedback on the overall functionality of the aid, highlighting its capability to reduce communication errors and enhance writing clarity (EP1, EP2) and provide useful perspectives to tweak the written post (EP3, EP5). Further, EP5 emphasized the need to use the writing aid to support social communication; she commented: \u201cSome of the big issues is kind of that impulsivity and not being able to kind of check and correct their own errors and stuff when posting\u2026First of all, does it make sense, what it\u2019s saying, but also kind of how that might come across to other people, as well.\u201d (EP5).\nExperts (EP1\u20135) also pointed out usability challenges of the aid based on the W3C guideline and suggested improvements, focusing on TBI users\u2019 cognitive and sensory needs. These suggested improvements included increasing font sizes (EP1); using simple and clear sentences for instructions (EP1\u20133); defining keywords used in the aid (e.g., \u201ctoxicity\u201d) (EP3); and providing more detailed suggestions or automatically implement the suggestions after the grammar checks (EP1, 3). EP2 suggested rewording the aid\u2019s instruction in a \u201cmore direct or simple\u201d way because of the diverse literacy levels of the patients she had worked with. EP2 shared, \u201cA lot of my patients that I work with who use social media a lot of the time, they come from backgrounds. Some of them don\u2019t have a lot of education.\u201d (EP2).\nFurthermore, experts (EP2, EP5) pointed out that oversharing personal information often happens for TBI users and suggested that the Writing Aid could \u201cadd in that extra level of security\u201d (EP5) to ensure the user\u2019s safety, such as sending out alerts when oversharing activity was detected (EP5). EP5 also suggested using verbal input to overcome the challenge of word-finding.\nThe Interpretation Aid was found to support comprehension of posts and images (P2, P6, P8), particularly for longer messages (P2), and two participants agreed that they would like to use it frequently (P1, P8). For example, P8 reported that \u201cRight after the accident, I had a really hard time understanding what people meant with their words\u2026This [aid] would have been really comforting to me.\u201d P6 appreciated that the aid provided a different perspective of the post, stating, \u201cit\u2019s nice to see how other people, same as earlier, like, could interpret what you\u2019re saying.\u201d\nThe major usability challenge reported by participants for the Interpretation Aid was disagreement with the results of sentiment analysis for the content (P2, P3, P7, P8). For example, P2 disagreed with the classification of the emotion type \u201cjoy\u201d for the post in the first interpretation task. P8 thought a post to be \u201cpositive\u201d while the aid predicted it to be \u201cnegative.\u201d Additionally, P2 noted confusion about the image information and thought the description of its emotion should be shortened.\nNotably, two participants (P1, 5) suggested that the aid provide more detail and explain the reason behind the interpretation results. For example, P1 commented: \u201cI want them to emphasize more, like, you know, why are they negative, why are they positive?\u201d (P1).\nThree expert participants (EP1, EP4, EP5) reacted positively to the Interpretation Aid. They appreciated that the aid could support social-emotional communication (EP1, EP4) and summarize the posts for individuals with TBI (EP5). For example, EP1 described how the aid can help users react to other people\u2019s social media posts, stating, \u201cThe aid would help them to know what the post is sort of about and whether to \u2018like\u2019 it or not. Maybe even determine whether it\u2019s a like or a \u2018love\u2019. Like if they were to learn that the greener it is the more chance the person is looking for a \u2018love\u2019, versus a yellow one the person is looking for a \u2019like\u201d\u2019 (EP1). Similar to the TBI users, experts also identified usability challenges for the aid, such as the need to improve the accuracy of interpretation results (EP1, EP2, EP5) and clarify the analyzed content (EP1, EP4).\nThree participants (P1, P3, P8) reacted positively towards the Focus Mode aid, and two participants reported that they would like to use it frequently (P1, P8). For example, P8 described the aid \u201camazingly helpful\u201d (P8) and shared, \u201cI read more captions than I would have if I was scrolling the newsfeed. They\u2019re bigger and easier to see.\u201d\nOn the other hand, five participants (P2, P4\u20137) held negative views towards the aid, finding it \u201cunnecessary\u201d (P2) and \u201ccumbersome\u201d (P5). Two major usability challenges reported by multiple participants were the post navigation for viewing the full content (P3\u20135, P8) and the unresponsiveness of the buttons (P2, P6\u20138). P5 described how the buttons for post navigation were inaccessible for users with motor impairments, stating \u201cIf you have, you know, in nimble fingers, and you can\u2019t really do that, or if you\u2019re old and don\u2019t know how to do it\u201d (P5). In addition to the above challenges, two participants (P5, P8) requested to increase the size of the post creator\u2019s profile photo and name texts.\nAll TBI expert participants provided positive feedback for the Focus Mode, highlighting its ability to enhance the usability of social media by streamlining the individual\u2019s feed (EP1\u20135) and the simplicity of use (EP1). For example, EP4 commented: \u201cWow. Okay, this is the best one. Wow, I can really focus on the posts.\u201d (EP4). Similarly, EP5 mentioned that \u201cYou can literally just focus on scrolling through your newsfeed. Yeah. This is cool.\u201d (EP5). The major usability challenge reported by TBI experts participants (EP3, EP4) is the interactivity of the blurred area. EP4 described how she accidentally clicked in the blurred area and went to an unexpected page: \u201cThe blur, I accidentally clicked and they went to a sponsor page.\u201d (EP4).\nFour participants (P1, P4, P6, P8) held positive views towards the aid, two participants (P2) held neutral views, and three (P3, P5, P7) reacted negatively to the aid. Two participants (P1, P8) agreed that they would like to use the aid frequently. In particular, P8 found it helpful that advertisements and posts were distinguished after applying the aid, stating that \u201cI think the advertisements being filtered away is something that makes it clear that I\u2019m looking at people\u2019s posts.\u201d (P8). However, three participants experienced usability challenges that the filtering was not accurate and did not sync up as experienced by three participants (P3, P4, P7). As P7 commented: \u201cI would say it\u2019s not very accurate. It\u2019s not personal to me.\u201d In addition, the filtering caused challenges for tracking viewed posts because of the posts hiding and reordering, as what P8 experienced refreshing the page: \u201cOne that I was just on is now gone\u201d (P8).\nParticipants (P2, P5, P8) suggested that the Filter Mode could have provided more options and combined multiple filters to achieve more customized results. For example, P2 compared the filter with Excel, and desired to have a wider range of filters such as \u201cQuotes\u201d and \u201cMeme.\u201d\nFilter Mode received positive feedback for its sorting feature and feed personalization (EP3\u20135) as well as its ease of use (EP3). As EP3 noted, \u201cIt\u2019s just helpful to be able to narrow down, like, the type of content that you want, what\u2019s most meaningful to them\u201d (EP3). However, some expert participants pointed out several usability challenges and provided suggestions for improvement, such as improving the accuracy of filtering results (EP2), making filter labels clearer (EP1, EP2), and increasing font size (EP3).\nSeven participants (P1\u20133, P5\u20138) held positive views toward the aid, and one participant (P4) was neutral. Three participants (P3, P7, P8) appreciated the ability to control the newsfeed with the tool and mentioned that the aid could make them \u201cmore focused\u201d (P5) and hide information that they \u201cdon\u2019t really need\u201d (P3), such as advertisements. On the other hand, one participant (P4) found this customization was not necessary because their goal of using social media was to \u201ccheck in and look around\u201d (P4), thus simplifying the information source would have a side effect for them to explore different content. P7 also wished that there were more options for the left-side filtering for him to \u201cpersonalize it a little bit further\u201d (P7). P7 also desired more guidance on how to use the aid.\nSimilar to the benefits mentioned by users with TBI, experts (EP1, EP3\u20135) noted that the tool simplified the newsfeed page and could help avoid distractions for users with TBI. EP1 noted, \u201cFor me as a user, I love this. I never looked at the stuff [extra fields on Newsfeed] before but I love it not being there. Look how much nicer that is to look at. I can ignore it with my own mind but I love not seeing it.\u201d Similarly, EP3 commented, \u201cThey have control over what they\u2019re seeing. This is very helpful\u201d (EP3).\nHowever, experts (EP1, 2) mentioned the current design could be further improved by clarifying the wording of the options (EP2) and using icons to support the user\u2019s understanding of the control (EP1)."

Based on our findings, we drew the following five design implications for designing accessible social media: ensuring psychological safety, privacy control and protection, trade off between the business profits and user experience, mixed feedback in AI-tools, tool adoption for diverse TBI needs.\nIndividuals with TBI can experience a variety of psychological challenges such as mood swings, depression, anxiety and agitation (Howlett et al., 2022  ###reference_b44###). Our user participants (P1, P2, P3) reported discomfort in seeing arguments or violent content on social media. Our expert participants (EP3, EP5) emphasized the importance of protecting TBI users\u2019 psychological safety and that the aid should give control to the content they are seeing. Our toolkit employed the use of the \u201cpositive\u201d filter to avoid disturbing content in the newsfeed, and future design could further explore design solutions to increase the accessibility of content browsing and social communication for populations with psychological challenges. For example, the aid could predict the psychological safety level of a page that the user is going to visit for the user so they can decide if they want to continue or not. The aid can also provide support for the user to disclose their negative feelings if the user sees the content causing emotional swings. One of our TBI user participants (P2) mentioned that she would talk to her partner if she experienced emotional swing after seeing discomforting content on social media. Similarly, the aid could create a virtual character for the user to chat to and disclose their negative feelings if they do not have other people to talk to in the moment.\nExpert participants cared for safety in using social media platforms and reported the possible oversharing activities by individuals with TBI in private messages and social media posts. This can be difficult to detect by individuals with TBI because they can be unaware of their behaviors or risks of oversharing on social media (Brunner et al., 2021  ###reference_b19###), especially for children and adolescents with brain injury. With more functional features provided on social media such as Market Place, it is easy for users to talk to strangers, which can be risky for TBI users. To prevent oversharing social communications, the user needs to always pay attention to who they are talking to and what they are sharing with. First, the aid can alert the user if they are talking to strangers and ask for confirmation before they message out any personal or sensitive information. Second, the aid could help the user monitor if there are any potential risks in the ongoing conversation and provide resources and clear instructions on how to handle dangerous situations. Social communication can happen in a variety of forms on social media such as private messaging, group chat, post comments and sharing. Therefore, privacy protection should be supported across social media features.\nAdvertisements on social media were reported as the main challenge by our participants with TBI (six out of eight). Advertisements in the news feed can add to TBI users\u2019 cognitive load, cause difficulties for them to main focus, and have them lost in the navigation. Moreover, individuals with TBI often have short-term or long-term memory loss and can forget people in their friend list, thus causing challenges for the users to differentiate advertisements and posts from their social circle. It is acknowledged that advertisements are important for the company to make profits, however, they are also the major barriers for individuals with TBI to use social media platforms. Social media platforms could change the layout of the webpage to separate advertisements from the posts from the user\u2019s social circle. As suggested by our participant (P8), there could be a specific area on the webpage dedicated to advertisements to reduce distraction. In addition, social media platforms could offer different modes of advertisements and allow users to choose the one that meets their needs. One mode could be the existing approach that advertisements are integrated into the newsfeed. An alternative mode could be showing advertisements at certain times such as when opening a new webpage, or always displaying advertisements in a centralized area to make the social media site more accessible for users with cognitive impairments.\nOne interesting finding was participants\u2019 perceptions of using AI tools for communication support, in particular the use of sentiment analysis and toxicity detection in our toolkit. We demonstrated the potential of using these tools in supporting message constructions and interpretations during social communications for individuals with TBI. Nevertheless, we acknowledged the potential risks of adopting AI tools for people with TBI. The major concern expressed by our participants is the inaccurate results from the interpretation. We employed an off-the-shelf commercial AI tool for the analysis, however, an accuracy level of 80% in the analysis caused much confusion for our participants as observed in the study. The inaccurate or biased results (Venkit et al., 2023  ###reference_b66###) in AI-based tools can be risky for people with TBI because they can have difficulty understanding underlying messages and differentiating the biased views from the AI tool, which can shape the way they think in the long term. In addition, AI tools are becoming more pervasive and available to the public and an increasing number of rehabilitation features are built on top of them (Alsobhi et al., 2022  ###reference_b5###). The pervasiveness and overconfidence of AI tools can reduce people\u2019s initiatives and willingness to seek professional rehabilitation support provided by TBI experts and negatively affect their recovery process.\nIndividuals with TBI can have diverse accessibility needs for using social media platforms. Through our study, participants with TBI reported specific desired features of the aids based on their personal needs, such as personalizing the Filter Mode with a \u201cMeme\u201d filter and using the Writing Aid to learn grammar (P2). Some participants preferred simplification of the interface using our cognitive support aids, while some preferred more complicated page layouts and richer interactions. Due to sensory challenges, participants have different preferences for the UI elements such as font and picture size.\nThe accessibility toolkit design should provide customized options for the user to choose their desired features. Moreover, the toolkit should provide adaptive learning support for TBI users for better tool adaption. The learning support should provide clear step-by-step guidance for the use and should be always available when needed by the user due to the memory challenges commonly faced by people with TBI."

+            "text": "Our work has several limitations in the capabilities of the aids as well as the conclusions we draw from our data.\nFirst, our aids relied on third-party APIs for text and sentiment analysis, which occasionally provided inaccurate interpretations. Significant errors in interpretation can impair user trust. Users with TBI might be particularly prone to the negative effects of errors due to their social communication challenges. Moreover, Hutchinson et al. (2020  ###reference_b47###) revealed that Perspective API used in the toolkit exhibited social biases towards disability-related terms and associated these terms with toxicity and negativity. Future work should incorporate bias mitigation techniques (e.g., Cheng et al. (2022  ###reference_b23###)) into the toolkit to prevent the harms from the socially biased analysis.\nSecond, our aids are still proof-of-concept prototypes and can be improved through integrating more advanced techniques. For example, Interpretation Aid can utilize tools for alt-text auto-generation (Wu et al., 2017  ###reference_b68###; Das et al., 2024  ###reference_b29###) to improve its image description. In addition, usability issues of our prototypes can limit the effectiveness of the aids and have a negative effect on user perceptions.\nThird, our evaluation took place in a laboratory environment for a short period of time, which offers little insight into long-term use and adoption patterns. In our future work, we plan to conduct an in-the-wild study with an extended period of time to reflect on user\u2019s actual use of the toolkit in their social media platforms.\nFinally, due to the difficulty of recruiting users with TBI as well as TBI rehabilitation experts, our study included a relatively small sample size, which prevented meaningful quantitative data analysis. Given the limited number of participants in our user evaluation (), our primary goal is to understand the potential and initial user experiences through a qualitative approach. Data from our quantitative measures (\u00a75.1.2  ###reference_.SSS2###) did not offer significant insights due to the potential lack of representativeness. However, the rich qualitative findings will guide the refinement of the toolkit for a more comprehensive and longer-term field study, where quantitative measures can be incorporated to assess the toolkit\u2019s effectiveness over an extended period."

The toolkit includes two communication support aids and three cognitive support aids. We evaluated the toolkit with eight social media users with TBI and five TBI experts. Our findings highlighted the effective features in the toolkit and pointed to areas of improvement for each aid. Based on our findings, we generated design implications to improve the accessibility of social media use by people with TBI, considering the psychological and privacy safety, the trade-offs between business profits and accessibility needs, mixed feedback for AI-based tools and tool adoption with diverse TBI needs. These design implications can inform the building of accessible social media platforms for users with cognitive and communication difficulties."

+    "title": "TESL-Net: A Transformer-Enhanced CNN for Accurate Skin Lesion Segmentation",
+    "abstract": "Early detection of skin cancer relies on precise segmentation of dermoscopic images of skin lesions. However, this task is challenging due to the irregular shape of the lesion, the lack of sharp borders, and the presence of artefacts such as marker colours and hair follicles. Recent methods for melanoma segmentation are U-Nets and fully connected networks (FCNs). As the depth of these neural network models increases, they can face issues like the vanishing gradient problem and parameter redundancy, potentially leading to a decrease in the Jaccard index of the segmentation model. In this study, we introduced a novel network named TESL-Net for the segmentation of skin lesions. The proposed TESL-Net involves a hybrid network that combines the local features of a CNN encoder-decoder architecture with long-range and temporal dependencies using bi-convolutional long-short-term memory (Bi-ConvLSTM) networks and a Swin transformer. This enables the model to account for the uncertainty of segmentation over time and capture contextual channel relationships in the data. We evaluated the efficacy of TESL-Net in three commonly used datasets (ISIC 2016, ISIC 2017, and ISIC 2018) for the segmentation of skin lesions. The proposed TESL-Net achieves state-of-the-art performance, as evidenced by a significantly elevated Jaccard index demonstrated by empirical results.",

The survival rate for melanoma patients drops below 15% if the disease is not detected early [2  ###reference_b2###]. Therefore, early detection is crucial to reducing mortality rates, with research indicating a 90% survival rate for patients diagnosed in the early stages. However, differentiating a melanoma lesion from the surrounding healthy skin is challenging. The appearance of the skin can be affected by various factors, including lesion size, hair, reflections, colors, marker colors, textures, shapes, and non-uniform illumination [3  ###reference_b3###].\nDermatoscopy is a non-invasive imaging technique widely used to identify skin lesions and their surrounding areas for the detection and diagnosis of skin cancer [4  ###reference_b4###]. Manual evaluation of dermoscopic images requires specialised knowledge in dermoscopy and is time-consuming. Even for highly experienced dermatologists, diagnosing skin cancer using only their unaided eye can be imprecise, unreliable, and time-consuming [5  ###reference_b5###]. Traditional image preprocessing techniques struggle with complex tasks due to their reliance on highly customised and precise features and methods [6  ###reference_b6###]. To improve the efficacy of lesion analysis and identification, dermatologists have implemented computer-aided diagnostic (CAD) technologies [7  ###reference_b7###, 8  ###reference_b8###]. Precise segmentation is a critical component of any CAD-based diagnostic platform for skin cancer. This process improves the precision and effectiveness of skin lesion segmentation by providing essential quantitative information, including location, size, shape, and other characteristics [9  ###reference_b9###].\n###figure_1### ###figure_2### ###figure_3### ###figure_4### ###figure_5### ###figure_6### ###figure_7### ###figure_8### ###figure_9### ###figure_10### Skin lesion segmentation presents several challenges [10  ###reference_b10###]. Precisely delineating skin lesions is often difficult due to their irregular and blurry boundaries [11  ###reference_b11###, 12  ###reference_b12###]. Differentiating between the healthy surrounding skin and a lesion is also frequently challenging. In addition, the varying shapes, sizes, and colours of skin lesions further complicate their characterisation. Interference elements, including blood vessels, ruler traces, hairs, and ink speckles, add to the complexity of segmentation [13  ###reference_b13###, 14  ###reference_b14###]. These challenges are illustrated in Figure 1  ###reference_###, where lesions with diverse shapes, sizes and colours, as well as irregular and hazy boundaries, introduce redundancy that reduces performance [7  ###reference_b7###, 15  ###reference_b15###]. Low-contrast skin lesions from surrounding healthy tissues and interference elements such as blood vessels, filaments, and ink speckles add noise to images. These factors impede the development of advanced segmentation techniques.\nHowever, skin lesion segmentation presents several challenges [16  ###reference_b16###]. Precisely delineating skin lesions is often difficult due to their irregular and blurry boundaries. Differentiating between the healthy skin surrounding is also often challenging. In addition, the varying shapes, sizes, and colours of skin lesions further complicate their characterisation. Interference elements, including blood vessels, ruler traces, hairs, and ink speckles, add to the complexity of segmentation.

Low-contrast skin lesions from surrounding healthy tissue, and interference features such as blood vessels, filaments, and ink speckles add noise to images. These factors impede the development of advanced segmentation techniques.\n###figure_11### For the task of segmenting skin lesions, a variety of convolutional neural network (CNN) techniques, as well as attention-based approaches, have been explored. Bi et al. designed a network that extracts contextual and hierarchical information by integrating the combination of pyramidal features, residual connections, and dilated convolution [17  ###reference_b17###]. Tang et al. introduced DeepLabV3+, a CNN architecture that incorporates an advanced spatial pyramid pooling module to extract multi-scale features [18  ###reference_b18###]. Another notable example is the U-Net architecture [19  ###reference_b19###], which has become the industry standard for medical image segmentation, including skin lesions. The advent of deep learning has significantly improved the analysis of biological data and image segmentation [20  ###reference_b20###]. By effectively utilizing relevant features, deep learning methods outperform traditional methods in skin lesion segmentation. Segmentation performance has been further enhanced by improvements to the encoder-decoder architecture, including the implementation of efficient feature map learning procedures [21  ###reference_b21###].\nSegmentation model training can be enhanced by data augmentation techniques, such as rotation, scaling, and flipping, which increase the scale and diversity of datasets [22  ###reference_b22###]. To achieve optimal results, it is essential to carefully regulate the selection and extent of augmentation. Deep neural network models with numerous layers may encounter issues such as parameter redundancy and vanishing gradients. To address these challenges and achieve precise skin lesion segmentation, we have developed a transformer-enhanced CNN, TESL-Net. Our proposed technique ensures accurate segmentation of skin lesions while maintaining a model architecture."

These conventional methods typically involve threshold setting, feature selection, and image pre-processing. The emergence of deep learning has significantly advanced segmentation techniques, particularly with CNNS. Yuan and Lo developed an improved CNN for skin lesion segmentation [27  ###reference_b27###]. Furthermore, studies have also used multiscale connection blocks instead of traditional skip connections to capture features at both the low- and the high-level more effectively [28  ###reference_b28###].\nHasan et al. proposed a dermoscopic skin network that employs depthwise separable convolution to reduce the number of trainable parameters [29  ###reference_b29###]. Abhishek et al. devised a novel deep semantic segmentation method that takes advantage of data from multiple colour bands [30  ###reference_b30###]. To analyse the boundaries and contextual relationships of target objects, the DAGAN authors implemented a dual discriminator network [31  ###reference_b31###].\nAttention mechanisms have been extensively implemented in CNNs to facilitate various tasks, including semantic segmentation, identification, classification, and machine translation. This approach enables models to focus on the most relevant features, thus reducing computational demands by weighting the features to emphasise pertinent information and suppress irrelevant data [16  ###reference_b16###, 32  ###reference_b32###]. To optimise skin lesion segmentation, Chen et al. integrated self-attention within codec components [33  ###reference_b33###]. Zhang et al. developed an attention-directed filter within a U-shaped framework to convey spatial features for image segmentation [34  ###reference_b34###]. A channel attention strategy was implemented to enhance skin lesion segmentation in a generative adversarial network (GAN) [35  ###reference_b35###]. CS2-Net enhanced feature extraction by implementing dual attention strategies in both the spatial and channel domains [36  ###reference_b36###]. The AS-Net further improved segmentation performance by integrating spatial and channel attention techniques [37  ###reference_b37###]. Furthermore, networks like MFSNet [38  ###reference_b38###] increased segmentation efficiency by incorporating multiscale concepts with attention mechanisms."

At the encoder stage, two consecutive blocks of depth-wise convolution followed by the activation function and batch normalisation layer are applied. After that, a max pooling layer is employed to reduce the spatial dimensions of the features. Once the size of the feature maps is reduced a Swin transformer block is used to extract and refine the feature information patch-wise. The same operations are again applied on the feature maps by increasing the depth twice. It is important to mention that the proposed TESL-Net uses two max-pooling layers at the encoder stage so that the spatial information especially at the boundary can be kept intact. At the decoder stage of the proposed TESL-Net transposed convolution is used to upsample the feature maps followed by ReLU and batch normalization operations. Once the spatial dimensions are increased, the Bi-ConvLSTM is used between the encoder-decoder blocks to capture short-term details and long-term dependencies of the feature information. Two consecutive blocks of depth-wise convolution followed by the activation function and batch normalization layer are then employed to reconstruct the extracted feature information. The same operations are again applied on the feature maps by reducing the channel depth twice. Finally, the sigmoid layer is employed to predict the binary masks. The mathematical description of the proposed TESL-Net is as follows:\nLet  be the RGB image of size  given to the input layer. The Depthwise Separable Convolution (DWS-Conv) is applied to the input image followed by batch normalization  and the ReLU (Rectified Linear Unit) activation function  that helps in dealing with overfitting and introduces non-linearity into the network. The output is defined as:\nThe resulting feature map is again fed into  followed by ReLU and BN.\nThe feature map  is passed through the max-pooling operation and then processed by the Swin Transformer Block, which captures long-range dependencies and context information.\nA similar process is applied to the resulting feature map in the second convolutional block. It is defined as:\nSubsequently, a transposed convolution operation is applied to the encoder generated feature map to up-sample the feature maps, followed by a ReLU activation layer  and .\nThe feature map  and  from the encoder are reshaped and concatenated with the corresponding reshaped feature maps from the decoder. The outputs are then fed into the corresponding Bidirectional Convolutional LSTM (Bi-ConvLSTM) to capture temporal dependencies in both forward and backward directions.\nThe forward ConvLSTM is defined as:\nwhere , , and  are the forget, input, and output gates,  is the cell input activation,  is the cell state, and  is the hidden state.\nThe backward ConvLSTM operates similarly but in reverse temporal order. The Bi-ConvLSTM combines the forward and backward ConvLSTM outputs:\nThe respective outcomes of Bi-ConvLSTM are processed through DWS-Conv,  and  along with transposed convolution.\nThe final predicted mask is computed by applying a sigmoid to the last layer for binary segmentation.\n###figure_12### ###figure_13### ###figure_14### ###figure_15### ###figure_16### ###figure_17### ###figure_18### ###figure_19### ###figure_20### ###figure_21### ###figure_22### ###figure_23### ###figure_24### ###figure_25### ###figure_26### ###figure_27### ###figure_28### ###figure_29### ###figure_30### ###figure_31###"

Our method consistently outperformed the most advanced techniques in the ISIC 2016 dataset in every metric. Specifically, TESL-Net achieved a Jaccard index (IOU) score that ranged from 2. 11% to 8. 13% higher compared to SOTA methods. Our technique demonstrates superior performance in all evaluation criteria. Comparisons of visual results showing various challenges in skin lesion segmentation, such as artefacts, hair, irregular morphologies, and multiple lesions, are presented in Figure 3  ###reference_###. The TESL-Net method achieved SOTA segmentation results in the test data, effectively handling skin lesions with irregular shapes and varying sizes.\nTen cutting-edge techniques were used to illustrate the statistical comparison findings in the ISIC 2017 dataset, as presented in Table III  ###reference_###. TESL-Net achieved a Jaccard index (IOU) score of 2. 02% to 11. 22% higher than the SOTA methods. The visual results showing various challenges in skin lesion segmentation, such as irregular morphologies, hair, and artefacts, are shown in Figure 4  ###reference_###. It is evident that our TESL-Net consistently produces SOTA segmentation results in test data, effectively handling skin lesions with unusual shapes and variable sizes.\nEleven cutting-edge techniques are used to present the statistical comparison findings in Table IV  ###reference_### on the ISIC 2018. In terms of the Jaccard index (IOU), TESL-Net achieved a score of 2.22%\u201310.47% higher than the SOTA methods described. In the same vein, we also obtained visual results for various skin lesion challenges, including the presence of artefacts, low contrast, irregular morphologies, and small lesions. The visual results of numerous skin lesion challenges are illustrated in Figure 5  ###reference_###. Even for skin lesions with unusual shapes and variable sizes, our method generates SOTA segmentation results on test data."

+            "text": "We have developed TESL-Net, a novel and effective methodology for accurate skin lesion segmentation aimed at overcoming challenges in this field. Unlike traditional CNN-based encoder-decoders, TESL-Net utilises Swin transformer blocks in the encoder to efficiently extract contextual information from skin-lesion images globally. Further refinement of feature extraction is achieved by integrating a Bi-ConvLSTM module into skip connections. When evaluated on three publicly available benchmark datasets for skin lesion segmentation, TESL-Net outperformed a variety of SOTA methods. Despite its exceptional performance, we have identified areas for further improvement. We propose employing semi-supervised strategies to reduce data requirements for training by incorporating paired and unpaired data. TESL-Net is suitable not only for immediate medical imaging applications in skin segmentation but also holds promise for adaptation and expansion to other medical imaging and segmentation tasks."

The 3D Bin Packing Problem (3D-BPP), a well-known NP-hard problems [i3], is referred to as an optimization problem of packing multiple objects into a bin(s), while satisfying the bin capacity constraint [2]. The 3D-BPP can be tackled offline or online depending on whether all objects can be accessible or not. In terms of offline bin packing task, this setting assumes the prior knowledge of all objects, usually, finding the optimal packing sequence and optimal placement are involved in this setting. Typically, meta-heuristic algorithms have been employed to determine the optimal order sequence in previous studies [4], thereafter, heuristic algorithms, such as DBLF proposed by Korha and Mustaf [7] or HM proposed by Wang and Kris [8], are leveraged to determine where to place the object into the bin.\nCompared with offline bin packing, online bin packing is more challenging. Basically, the packing order is random, and the agent can only observe the upcoming objects (either single or multiple objects) as illustrated in Fig. 1  ###reference_###. In this context, relying exclusively on heuristics results in a considerable decline in bin utilization [4]. Under these constraints, Yang et al. [i4] employed unpacking-heuristics to improve the utilization. Nonetheless, this method raises the time cost, thereby diminishing the overall efficiency of the packing process.\nRecent progress in DRL has shown promising results in various domains by enabling models to learn optimal policies through trial and error [19]. Compared with heuristic algorithms, DRL excels in addressing optimization problems effectiveness in complex environments. However, real-world physical law damages the training efficiency as learning the physics in complex environment takes many trial-and-error iterations, and the stable placement cannot be guanranteed. Zhao et al. [14] and Yang et al. [i4] leveraged neural network to predict the physical feasibility map, enabling the agent to learn feasible packing strategies. Although these methods have achieved promising results in 3D-BPP, object stability is not guaranteed. To address these challenges, we propose an efficient and effective DRL framework using a highly reliable physics heuristic algorithm for online 3D-BPP. The main contributions of this paper are as follows.\nWe proposed a highly reliable physics heuristic algorithm that guarantees the stability of object placement in complex multi-stack environments, while retaining as many placement positions as possible.\nWe incorporated an object rearrangement process into the proposed framework which allows the robot manipulator to change the orientation of the upcoming object. It is also an efficient action that directly enhances space utilization without requiring additional time costs.\n###figure_1###"

However, 3D-BPP become unsolvable within a reasonable time frame using exact algorithms [1] when involving a large number of objects. Over the years, various heuristic and meta-heuristic methods have been developed to address this problem [5][6][7][9]. Heuristic algorithms critically depend on the sequence of object placement, and current research often employs meta-heuristic techniques such as simulated annealing [13] and genetic algorithms [7].\nConsequently, if complete information on all objects to be packed is unavailable, the effectiveness of heuristic algorithms drops significantly. Moreover, in real-world logistics warehouse, gathering detailed information about all objects can be challenging and time-consuming, reducing operational efficiency. Therefore, We propose using the object rearrangement method to change the orientation of objects in order to improve bin utilization, under the constraints of unchangeable order sequence."

Furthermore, it can be adaptable to changing conditions and provide feasible solutions with highly efficient [19], where traditional methods may struggle to find efficient solutions. DRL has recently demonstrated strong performance across various robotics tasks [17][18], showcasing its ability to handle complex spatial and dynamic challenges effectively.\nThus applying DRL to the 3D-BPP could indeed be a highly efficient approach. For example, Zhao et al. [14] introduced a prediction-and-projection scheme where the agent first generates a physical stability mask for placement actions as an auxiliary task, then using this mask to adjust the action probabilities output by the actor during training. However, DRL models can suffer from instability and sensitivity to hyperparameters, making them difficult to tune and sometimes resulting in unpredictable performance. Moreover, most work focuses only on sample constraints, without considering real-world physical properties of objects, including the object CoM and its deviation in a complete stack. These factors can result in solutions that are impractical for real-world applications where physical stability and balance are essential.\nThus we propose the DRL framework integrated with a physics heuristics. This not only guarantees the stability of object placement but also enhances the training efficiency of the model, allowing for faster convergence."

This not only lengthens the training time for the model but also causes fluctuations in model convergence.\nTherefore, for 3D-BPP, it is necessary to design a reliable and efficient physics heuristics for feasible action detection to quickly rule out incorrect actions in the current state. Zhao et al. [14] and Yang et al. [i4] use the similar scheme that combines the ratio of overlapping parts between the placed item and its contact items with a neural network model for prediction. But this is not a reliable method, since the model is a black box, there are always parts that are inexplicable and unpredictable. On the other hand, Wang and Kris [8] proposed a mathematical model that using a linear programming method solves for the torque balance and force balance of the object for all contact forces. Although this is a very reliable method,it is too complex for regular objects and usually takes a long time to evaluate all the candidates actions.\n###figure_2### Thus we propose a new physics heuristic algorithm for rectilinear objects, which can guarantee the stability of object placement in an efficient and effective way, under real-world physical constraint.\n###figure_3###"

But our method is not limited by the mass distribution, here just for simplify questions. For uneven objects, we can use Gao et al. [gao2][gao1] to estimate as close as possible the CoM.\nFor the current state bin , we generate a bottom-to-top depth heightmap with a resolution of , where each voxel represents a 5  vertical column of 3D space in the agent\u2019s workspace. The object to be placed  is defined by its dimensions . We employ a  sliding window to traverse the height map to check the stability of each placement.\nBased on physics\u2019 principles, we introduce the convexHull-1 method, as shown in Fig. 2  ###reference_###. The upward support force, denoted as  is defined as the set of highest points in the window, obtained by object  under currently placement. We utilize OpenCV [22] to calculate the largest convex hull formed by . Then, we evaluate the placement stability by verifying if the center of the sliding window is within the convex hull or not. During our experiments, we observed that relying only on a single layer of the convex hull cannot ensure the stability of object placement. Fig. 3  ###reference_### shows an example using convexHull-1 for stability check and fail.\nTo address the aforementioned issue, we introduce convexHull-, for managing multiple stacks of objects in complex environments. Throughout the object packing procedure, we maintain an empty map with the same size as the action map. The main concept of covexHull- is that the supporting force must be vertical and originate from the ground. Basically, for each position inside the sliding window, we check the number of wasted voxels along the  axis. We consider that only no wasted voxels can be the reliable support force, which corresponds to the empty map value is zero, denoted as . After each placement, we update the empty map outlines in Algorithm 2  ###reference_###.

+    "abstract": "Recently, Transformers have gained traction in weather forecasting for their capability to capture long-term spatial-temporal correlations. However, their complex architectures result in large parameter counts and extended training times, limiting their practical application and scalability to global-scale forecasting. This paper aims to explore the key factor for accurate weather forecasting and design more efficient solutions. Interestingly, our empirical findings reveal that absolute positional encoding is what really works in Transformer-based weather forecasting models, which can explicitly model the spatial-temporal correlations even without attention mechanisms. We theoretically prove that its effectiveness stems from the integration of geographical coordinates and real-world time features, which are intrinsically related to the dynamics of weather. Based on this, we propose LightWeather, a lightweight and effective model for station-based global weather forecasting. We employ absolute positional encoding and a simple MLP in place of other components of Transformer. With under 30k parameters and less than one hour of training time, LightWeather achieves state-of-the-art performance on global weather datasets compared to other advanced DL methods. The results underscore the superiority of integrating spatial-temporal knowledge over complex architectures, providing novel insights for DL in weather forecasting.",

+            "text": "Accurate weather forecasting is of great significance in a wide variety of domains such as agriculture, transportation, energy, and economics. In the past decades, there was an exponential growth in the number of automatic weather stations, which play a pivotal role in modern meteorology (Sose and Sayyad 2016  ###reference_b23###). They are cost-effective for applications (Bernardes et al. 2023  ###reference_b2###; Tenzin et al. 2017  ###reference_b24###) and can be flexibly deployed to almost anywhere around the world, collecting meteorological data at any desired resolution.\nWith the development of deep learning (DL), studies have embarked on exploring DL approaches for weather forecasting. The goal of data-driven DL methods is to fully leverage the historical data to enhance the accuracy of forecasting (Schultz et al. 2021  ###reference_b19###). The weather stations around the world are ideally positioned to provide a substantial amount of data for DL methods. However, the observations of worldwide stations exhibit intricate spatial-temporal patterns that vary across regions and periods, posing challenge for global-scale weather forecasting (Wu et al. 2023b  ###reference_b29###).\n###figure_1### Recently, Transformers have become increasingly popular in weather forecasting due to their capability to capture long-term spatial-temporal correlations. When confronting the challenge of global-scale forecasting, Transformer-based methods employ more sophisticated architectures, leading to hundreds of millions of parameters and multiple days of training time. In the era of large model (LM), this phenomenon become particularly evident. Such expenses limit their scalability to large-scale stations and restrict their application in practical scenarios (Deng et al. 2024  ###reference_b7###).\nDespite the complexity of these architectures, we observe that the resulting improvements in performance are, in fact, quite limited. This motivates us to rethink the bottleneck of station-based weather forecasting and further design a model as effective as Transformer-based methods but more efficient and scalable. For this purpose, we delve deeper into the architecture of Transformer-based weather forecasting models and obtain an interesting conclusion: absolute positional encoding is what really works in Transformer-based weather forecasting models, and the reason lies in the principle of atmospheric dynamics.\nPositional encoding is widely regarded as an adjunct to permutation-invariant attention mechanisms, providing positional information of tokens in sequence (Vaswani et al. 2017  ###reference_b26###). However, we empirically find that absolute positional encoding can inherently model the spatial-temporal correlations of worldwide stations, even in the absence of attention mechanisms, by integrating 3D geographical coordinates (i.e., latitude, longitude, and elevation) and real-world temporal knowledge.\nFurthermore, we will theoretically elucidate why absolute positional encoding is pivotal by applying principles of atmospheric dynamics. In the global weather system, the evolution of atmospheric states is closely related to absolute spatial and temporal conditions, resulting in complex correlations. Absolute positional encoding enables the model to explicitly capture these correlations rather than blind guessing, which is the key bottleneck in model performance.\nBased on the aforementioned findings, we propose LightWeather, a lightweight and effective weather forecasting model that can collaboratively forecast for worldwide weather stations. It utilizes the absolute positional encoding and replaces the main components of Transformer with an MLP as encoder. Benefiting from its simplicity, LightWeather significantly surpass the current Transformer-based models in terms of efficiency. Despite its efficiency, LightWeather also achieves state-of-the-art forecasting performance among 13 baselines. Figure 1  ###reference_### visualizes LightWeather\u2019s lead in both efficiency and performance. Moreover, it is worth noting that the computational complexity of LightWeather grows linearly with the increase of the number of stations  and the parameter count is independent of . Therefore, LightWeather can perfectly scale to the fine-grained data with a larger .\nOur contributions can be summarized as follows:\nWe innovatively highlight the importance of the absolute positional encoding in Transformer-based weather forecasting model. Even in the absence of attention mechanisms, it helps model to explicitly capture spatial-temporal correlations by introducing spatial and temporal knowledge into the model.\nWe propose LightWeather, a lightweight and effective weather forecasting model. We utilize the absolute positional encoding and replace the main components of Transformer with an MLP. The concise structure endows it with high efficiency and scalability to fine-grained data.\nLightWeather achieves collaborative forecasting for worldwide stations with state-of-the-art performances. Experiments on 5 datasets show that LightWeather can outperform 13 mainstream baselines."

For instance, MGSFformer (Yu et al. 2024a  ###reference_b32###) and MRIformer (Yu et al. 2024b  ###reference_b33###) employ attention mechanisms to capture correlations from multi-resolution data obtained through down sampling. However, attention mechanisms take quadratic computational complexity for both spatial and temporal correlation modeling, which is unaffordable in global-scale forecasting.\nSeveral studies attempted to enhance the efficiency of attention mechanisms. Typically, AirFormer (Liang et al. 2023  ###reference_b13###) restricts attention to focusing only on local information. Corrformer (Wu et al. 2023b  ###reference_b29###) employs a more efficient multi-correlation mechanism to supplant attention mechanisms. Nevertheless, these optimizations came with a greater amount of computation and parameter, resulting in limited improvements in efficiency."

Here we theoretically demonstrate this relationship.\nLet  be the longitude, latitude and elevation of a weather station and  is a meteorological variable collected by the station, then the time evolution of  is a function of  and time :\nWe provide the proof with zonal wind speed as an example; analogous methods can be applied to other meteorological variables.\nAccording to the basic equations of atmospheric dynamics in spherical coordinates (Marchuk 2012  ###reference_b16###), the zonal wind speed  obeys the equation:\nwhere ,  is pressure,  is atmospheric density,  is zonal friction force, and  is geocentric distance.\nThe geocentric distance can be further denoted as , where  is the radius of the earth and  is the elevation. Since  is a constant and , we have  and we can approximate  with .\nIt is possible to render the left side of the equation spatial-independent by rearranging terms:\nTherefore, we have\n\u220e\nConsidering the use of historical data spanning  steps for prediction, it is not difficult to draw the corollary:\nwhere  is the historical data, and .\nThe detailed proof is provided in Appendix A.1. According to Eq.

When the scale is small, e.g., in single-station forecasting, even a simple linear model can achieve great performances (Zeng et al. 2023  ###reference_b35###). However, as the scale expands to global level, modeling  becomes the key bottleneck of forecasting.\nThe majority of prior models are designed to fit historical observations more accurately by employing increasingly complex structures. As shown in Figure 3  ###reference_### (a) (b), they simplistically regard  as a function of historical values, and the complex structures may lead to over-fitting of it. In comparison, LightWeather can explicitly model  with  introduced by absolute positional encoding, as shown in Figure 3  ###reference_### (c), thereby enhancing the predictive performance.\nWe theoretically analyze the efficiency of LightWeather from the perspectives of parameter volume and computational complexity.\nThe total number of parameters required for the LightWeather is .\nThe proof is provided in Appendix A.2.

In addition, the computational complexity of LightWeather grows linearly as the increase of . In canonical spatial correlation modeling methods (Wu et al. 2019  ###reference_b30###), it will cause quadratic complexity and linear increase of parameters with respect to , which is unafforable with large-scale stations.

Specifically, relative spatial encoding embeds the indices of stations instead of the geographical coordinates. Kindly note that we project the temporal dimension of data into hidden space, thus there is no need for relative temporal encoding. The results are shown Exp. 3 of Table 3  ###reference_###. It is notable that the adoption of relative positional encoding causes a degradation in performance. Moreover, comparison between Exp. 1 and 3 reveals that the use of relative positional encoding even results in poorer performance than the absence of positional encoding, which further substantiates the effectiveness of absolute positional encoding.\nWe investigate the effects of two important hyperparameters: the number of layers  in MLP and the hidden dimension .

Subsequently, we present LightWeather, a lightweight and effective weather forecasting model. We utilize the absolute positional encoding and replace the main components of Transformer with an MLP. Extensive experiments demonstrate that LightWeather can achieve satisfactory performance on global weather datasets, and the simple structure endows it with high efficiency and scalability to fine-grained data. This work posits that the incorporation of geographical and temporal knowledge is more effective than relying on intricate model architectures. This approach is anticipated to have a substantial impact beyond the realm of weather forecasting, extending its relevance to the predictions that involve geographical information (e,g., air quality and marine hydrology) and illuminating a new direction for DL approaches in these domains. In future work, we plan to integrate the model with physical principles more closely to enhance its interpretability."

+    "abstract": "Proper representation of data in graphical visualizations becomes challenging when high accuracy in data types is required, especially in those situations where the difference between double-precision floating-point and single-precision floating-point values makes a significant difference. Some of the limitations of using single-precision over double-precision include lesser accuracy, which accumulates errors over time, and poor modeling of large or small numbers. In such scenarios, emulated double precision is often used as a solution. The proposed methodology uses a modern GPU pipeline and graphics library API specifications to use native double precision. In this research, the approach is implemented using the Vulkan API, C++, and GLSL. Experimental evaluation with a series of experiments on 2D and 3D point datasets is proposed to indicate the effectiveness of the approach. This evaluates performance comparisons between native double-precision implementations against their emulated double-precision approaches with respect to rendering performance and accuracy. This study provides insight into the benefits of using native double-precision in graphical applications, denoting limitations and problems with emulated double-precision usages. These results improve the general understanding of the precision involved in graphical visualizations and assist developers in making decisions about which precision methods to use during their applications.",

+            "text": "Nowadays, computer graphics tools play a significant role in high-precision data modeling and display for several themes within science and engineering. They make an impact on decision-making and consequent results in very diverse domains, from scientific research to gaming. High-precision molecular dynamic simulation [1  ###reference_b1###], an attempt at film-game integration [2  ###reference_b2###], next-generation AI-based games [3  ###reference_b3###], the open-source dynamic simulation framework YADE [4  ###reference_b4###], three-dimensional reconstruction using [5  ###reference_b5###], and ray tracing of CAD-based simulation [6  ###reference_b6###] are some of the studies which underpin the need.\nIn graphical models, precision and accuracy are vital and are mostly used in scientific computing, medical imaging, and engineering simulations. These models guarantee to convey complex and comprehensive information precisely and accurately. The ancillary problem here is obtaining correct data types, mainly distinguishing double-precision from single-precision floating-point types, which turn out to be very influential. This kind of technology is, however, vision-limited to some level of accuracy, hence less valuable if even higher levels of precision are called for. It is, hence, important to pick an alternative that offers precision and, importantly, the level of accuracy required by the application or the project.\nProcessing and visualizing double-precision data present several challenges, such as computational intensity [7  ###reference_b7###], hardware and software support [8  ###reference_b8###] [9  ###reference_b9###], and rounding errors [10  ###reference_b10###] [11  ###reference_b11###], mainly due to the complexity and precision requirements of this type of data.\nThe choice of API in high-accuracy applications is based on each API\u2019s appropriateness. With changing application requirements, the suitability of each API changes: OpenGL [12  ###reference_b12###], Vulkan [13  ###reference_b13###], DirectX [14  ###reference_b14###], OpenCL [15  ###reference_b15###], and CUDA [16  ###reference_b16###] . Vulkan is a much newer API compared to OpenGL and gives a developer much more acute control over GPU processes, significantly improving rendering performance and speed. Direct3D is the most frequently used graphics API for game and multimedia applications that run on Windows systems. OpenCL is a portable programming language that can be run on various devices, hence the reason why OpenCL applications are highly portable across a wide variation of hardware like a GPU and CPU.\nIn the case of high-precision visual representation using Vulkan API and GLSL [17  ###reference_b17###], complicated technical details shall be addressed in the analysis of double-precision and single-precision floating-point data. One major reason could be the accuracy differences that, in turn, compromise both performance and memory consumption. In old generations of GPU hardware, a representation of double-precision data often emulated single-precision floating-point numbers. Modern GPUs have, however, come with support for double-precision data in their design. This research is based on recent versions of GLSL supporting both single and double precision. The evaluations taken into consideration for this research are to frame the differences between single-precision and double-precision data representations. In this paper, the approaches are compared with respect to visualization performance, where a rendering operation differs in both. This comparison will provide important information about which graphics API is more suitable for applications requiring high precision and will provide guidance for current applications in the field of graphics programming. Additionally, current challenges in processing and visualizing double-precision floating-point data and methods to overcome these challenges will be discussed.\nIn view of the requirement of accuracy in graphics visualizations, primarily due to real-world applications in science and engineering, this research is done to find out how double-precision floating-point data visualizations realize performance gains using the Vulkan API. The specific research questions that guided this study were as follows:\nRQ 1. How does the performance of native double-precision floating-point implementations compare to emulated double-precision implementations in Vulkan for rendering 2D and 3D points datasets?\nRQ 2. How does the scalability of double-precision floating-point data visualization in Vulkan API hold up with increasing dataset sizes?"

Various floating-point approaches have been developed using graphics APIs and game engines. However, this section examines closely related approaches like emulated double-precision, hardware and software-based double-precision, and extended precision.\nDa Gra\u00e7a & Defour [18  ###reference_b18###] demonstrated a 44-bit solution emulating floating-point formats and corresponding operations, which increased the precision for applications that need more than the single precision, complemented with detailed performance and accuracy results. This implementation enabled straightforward and efficient operations for adding, multiplying, and storing floating-point numbers. It is shown that the research in compensated algorithms with float-float representation runs more efficiently for comparable accuracy, and adapting these algorithms to the GPU constitutes a significant part of future research.\nThall [19  ###reference_b19###] introduced \u2019doublefloats\u2019 for extended precision representation of floating point numbers for GPU computation. This representation, while improving accuracy without performance degradation on a GPU, comes at the cost of resources by exploiting the inherent parallelism in it. Doublefloats are constructed from unevaluated sums of 32-bit floats and deliver a precision of 48 significant bits. This approach\u2014crucial for very high precision applications\u2014necessarily restricted the use of GPU hardware. This shows, with the help of the Mandelbrot Set Explorer, both the utility of doublefloats and some potential applications in simulation, scientific computing, and image analysis.\nIn the OpenSpace [20  ###reference_b20###] study, the limitations of floating-point numbers in computers and the various methods developed to ensure accurate representation of large-scale astronomical data are discussed. With the method it offers, OpenSpace manages to solve precision problems by using Dynamic Scene Graph and rendering objects at the correct distances relative to the camera in cases where single-precision floating-point numbers are insufficient. This method enables accurate and efficient visualization of large-scale astronomical data and minimizes floating-point precision problems.\nDally et al. [21  ###reference_b21###] review the progress of GPUs from special-purpose hardware for 3D graphics to powerful programmable processors applied in HPC and deep learning. It reflects all significant steps of this development, including the creation of CUDA, the introduction of double-precision floating-point arithmetic, and other innovations like Tensor Cores that have increased the performance and flexibility of contemporary GPUs manyfold. These results depict that in the future, a GPU will keep evolving to provide high performance and support many applications.\nKaufmann et al. [22  ###reference_b22###] addresses the challenges and limitations inherent in real-time physics simulations in large-scale environments, primarily due to the imprecision of single-precision floating-point calculations. The authors solve a limitation where traditional physics engines still rely on single-precision floating-point numbers by proposing a system in which the subdivision of the simulation world into independent sectors takes place, and these sectors are allocated dynamically. It drastically reduces the occurrence of precision errors through cloning at sector boundaries, ensuring very consistent and accurate interaction across these sectors. It has hugely improved the precision and efficiency of real-time physics simulation in large-scale virtual environments by dividing the world into independently simulated, dynamically allocated sectors and using a cloning system to maintain accurate interactions at sector boundaries.\nThe progress report [23  ###reference_b23###] on the Godot Engine reviews challenges to render big worlds in games with single-precision floating-point numbers that lead to precision errors and jerky motions. The report explores solutions such as using double-precision in calculations but handling its impracticability again due to the limits of GPU. The final solution considered is emulating double precision by using two single precision floats for specific matrix calculations, where they preserve the accuracy and precision without much penalty in performance."

This paper explores several aspects of GPU pipeline advancements and applications as described in recent literature.\nAll pipeline stages concerning rasterization, pixel processing, and abstract geometry processing are implemented on the GPU. Internally, these are divided into a range of hardware stages with differing levels of programmability or configurability. The API provides an access method for the programmer to the logical model of a GPU; the actual implementation of this conceptual process in hardware is left to the manufacturer. The pipeline of the GPU processes graphical input through many phases, from the original vertices to the final pixel rendering, with differing degrees of programmability. The fully programmable vertex shader stage is responsible for perspective projection, lighting, model space to view space transformations and vertex shading. Another programmable stage is Geometry Shader, which deals with entire primitives to generate or to modify them and construct complex effects, including particle systems and shadow volumes.\n###figure_1### Stream output reuses processed data and is thus useful for effects like hair rendering. Fixed-function stages are triangle preparation and traversal, where triangles are prepared and rasterized into pieces; screen mapping, which translates the vertices from clip space into screen space; and clipping, which cuts triangles beyond the viewing frustum. There may be removal of occluded pieces based on the early z-test step, which is varied across GPUs for increased efficiency. The programmable pixel shader processes every fragment to provide texture and color effects. The final step, raster ops or blending, is where colors are combined, and other pixel tests, like depth and alpha testing, are managed. This pipeline consists of both fixed and programmable steps; both are required to efficiently render complex images. [24  ###reference_b24###] [25  ###reference_b25###]."

The Vulkan API has been designed to give much more direct control over the GPU, thus allowing finer-grained optimizations and efficient usage of the GPU. Vulkan significantly reduces driver overhead compared to older graphics APIs. Such overhead may yield great performance, particularly in CPU-bound applications. It also designs the API to be more predictable and with fewer errors, clear performance benefits from keeping the GPU busier, producing fewer bottlenecks than those caused by the CPU [26  ###reference_b26###]. Vulkan is characterized by its verbosity and fragility, but it provides enhanced control, a streamlined threading architecture, and superior performance. It provides functionality for transport, computation, and graphics and may be chosen as an option [27  ###reference_b27###]. The Vulkan Specification mandates a host environment with runtime support for 8-16, 32, and 64-bit signed and unsigned twos-complement integers, 32- and 64-bit floating-point types satisfying range and precision constraints, and ensuring their representation and endianness match those on every supported physical device."

Recent developments in this area include the integration of GLSL with all major graphics APIs and its application in parallel computing cases.

Each format includes a sign bit, an exponent section, and the mantissa part (fraction) [30  ###reference_b30###].\nThe single-precision floating-point format defined in IEEE Std 754-2019 utilizes a 32-bit (4-byte) structure. This format consists of a 1-bit sign bit, telling whether a number is positive or negative, an 8-bit exponent defining the scale of the number adjusted by a predefined \"bias\" value, and a 23-bit fraction representing the significant or mantissa part of the number. The single-precision format provides an accuracy of about 7 decimal digits while it covers a very wide range of values. This would normally be used in cases where speed is very essential and very fine precision is not required, for example, in the processing of graphics or audio [31  ###reference_b31###] [32  ###reference_b32###].\n###figure_2### The format, otherwise known as double-precision floating point, is 64-bit (8-byte) in size. Much like the single precision, the format contains a 1-bit sign bit but reserves 11 bits for the exponent and 52 bits for the fraction. These give double precision a much greater range and much higher precision. This format provides an accuracy of about 15\u201316 decimal digits and is preferably used where high accuracy is required, like in scientific computations and precision engineering tasks.\nThe IEEE 754 standard standardizes the way of representation and processing of floating-point numbers within a computer system. This creates consistency and reliability for numerical computations. The standard provides for the accuracy of numerical operations across different systems and by different languages.

The first rounding may be toward a midpoint which then gets rounded again, moving it further from the closest correct value [35  ###reference_b35###]. Consider the number 3.1415926 that is represented base-10. The higher precision will round to three decimal places while the lower precision will round to the nearest integer. The higher precision rounds 3.1415926 to 3.142. When this result is then rounded to a lower precision it becomes 3. When 3.1415926 is rounded directly to the nearest integer, omitting the intermediate step the answer is again 3 so in this case there is no inaccuracy. A slight modification of the situation can make double rounding significant. For instance, if the exact value was 3.6515926 then rounding first to the higher precision gives 3.652 and further rounding to the lower precision gives 4. Rounding directly from 3.6515926 to the nearest integer gives 4 also so differences need not appear in every case, yet are of vital significance in the vicinities of some number values [36  ###reference_b36###] [37  ###reference_b37###]."

+            "text": "Most modern graphics and compute target applications rely on floating-point operation accuracy, which brings about dramatic performance and quality impacts. On the other side, single-precision versus double-precision floating-point implementations represent a compromise in both computational performance and accuracy for high-performance graphics rendering. This section describes a comparative study of both under the Vulkan API framework, pointing out each of their benefits and tradeoffs. In conjunction with the explanation, the diagram provided shows the Vulkan-based application \u2014 the full extent of which will initialize and manage GPU resources for rendering both 2D and 3D point datasets to cover in detail how the choice of precisions affects the resultant rendering and performance metrics.\n###figure_6### The first step is to create a Vulkan instance. A Vulkan instance is an instance that lets the application interact with the Vulkan API. Immediately following the creation of the Vulkan instance, a debug messenger is created for debugging during the development process. Following this, inter-functioning the windowing system with the surface creation is done. All core Vulkan API elements have been created at this stage, which would now allow an application to use the GPU.\n###figure_7### Another core stage in managing the rendering of graphics using Vulkan is logical device setup. This logical device provides an interface with the GPU from the application. It enables a number of commands to be executed. At this stage, Command Buffers are allocated for the storage of rendering commands. Synchronization objects, like Semaphores and Fences, are created to control the synchronicity in the execution of commands. A Vertex Buffer is also allocated for vertex data. These parts ensure that all rendering processes go through smooth and concurrently.\nThis can do high-performance graphics operations with the Vulkan API by creating a Graphics Pipeline. It describes the process of rendering\u2014a pipeline starting from processing vertices up to fragment shading. Shader Modules are loaded into the pipeline to handle certain parts of the rendering process. Rendering output is controlled by the arrangement of Render Passes and Framebuffers. Therefore with such structure, it is possible to execute efficiently complex graphics operations.\nIt involves all rendering commands, ance drawing 2D and 3D points, updating the Framebuffers, and, finally, memory allocation to manage one buffer\u2014the so-called Buffer Memory\u2014which contains vertex data and other related information regarding the rendering process. In this step, it will be finalized how an application is going to handle its rendering process to present the final output. Finally, memory is allocated to manage one buffer\u2014the so-called Buffer Memory\u2014which contains vertex data and other related information regarding the rendering process. Efficient memory management has been taken into consideration to ensure that.GUI resources are used effectively.\nControl and data flow between Host Machine and GPU Host machine components: Points Dataset, SPIR-V Generator, Application, Camera Control. A Points Dataset, prepared, typically, in CSV format, contains 2D and 3D points. A SPIR-V Generator generates a low-level representation from an input high-level source representation, such as high-level shaders, for execution on a GPU. The Application is in charge of the entire rendering process and communicates with the Vulkan API. Camera Control deals with how the visualization is to be viewed.\nThe device components include the GPU, Physical Device, Shader Cores, Compute Units, Rasterizer, and Framebuffer. Each of these is one of the key elements in a rendering pipeline, and together they allow high performance in graphics-oriented operations.\nOnce the shaders are written in GLSL, they need to be compiled into SPIR-V, which is the intermediate representation used by Vulkan. The compilation process ensures that the shaders are optimized and can be executed efficiently on the GPU. The compilation can be done using tools like \u2018glslangValidator\u2018. The compiled SPIR-V shaders are then integrated into the Vulkan pipeline [40  ###reference_b40###] [41  ###reference_b41###]. The steps include creating shader modules, setting up the pipeline, and binding the necessary resources. Below is an example of how the shader modules are created and integrated:\nThe created shader module is then used in the graphics pipeline to execute the vertex and fragment shaders. By providing a detailed explanation of the shader code, its compilation, and integration into the Vulkan pipeline, this section offers a comprehensive understanding of how native double-precision floating-point operations are utilized in Vulkan applications."

Bailey\u2019s approach in the DSFUN90 library [42  ###reference_b42###].\nThis algorithm aims to store a double precision floating point number by dividing it into two single precision floating point numbers. First, the variable value is converted to a single precision floating point number and assigned to the variable high. This step is to obtain a lower precision representation of value. The high value is then converted back to a double precision number and assigned to the highDouble variable. This conversion is necessary for comparison with the original value. Finally, the difference is calculated by subtracting highDouble from the value, and this difference is assigned to the low variable as a single precision number. Thus, the variables high and low are stored as a two-part representation of the original double-precision value. This method is especially useful when precision is essential and memory savings are required."

Later, the shaders were compiled into SPIR-V, which represents the Vulkan Intermediate Representation.\nThis is a vertex shader written in GLSL, version 4.5.0, with the GL_ARB_gpu_shader_fp64 extension. The program uses a push constant block called PushConstants, including a member of type dmat4 for an MVP matrix. It also has an input of type dvec3 for position and color, and finally defines a variable named fragColor of data type flat dvec3 to create its output. In the main function, declare a dvec4 vector with a pos data and 1.0. Multiply the vector by the MVP matrix and assign it to gl_Position. Finally, assign the input color to the fragColor variable."

The algorithms and open-source libraries used for dataset production are explained in Appendix A. The same datasets were used for both emulated double-precision experiments and native double-precision experiments. The experiments were conducted using NVIDIA RTX 3090 GPU, Intel(R) Core(TM) i7-6850K @3.60GHz CPU, and 44 GB DDR4 RAM hardware components. The framerate was recorded using the RenderDoc [43  ###reference_b43###] v1.33.\n###figure_9### ###figure_10### ###figure_11### Experiments demonstrate the advantages of using native double-precision arithmetic within Vulkan. Performance measurements indicate that rendering time for a large dataset improves significantly. The results for native double precision are summarized in the tables below.\nThe data in Table 2 indicates that, in general, the emulated double-precision floating point calculations are worse when compared to native calculations. Generally, the render times are longer and frame rates are lower. For example, the render time for a 3D Menger Sponge with 11.9 million vertices was up to 499.12 milliseconds. The highest frame rate observed was 729 fps for 3D Mandelbulb with 200K vertex.\nNative Double Precision Floating Point Calculations\nData in Table 3 clearly indicates that natively provided double precision excels in performance compared to emulated calculations. In most cases, render times are shorter, along with frame rates that become higher. For instance, 3D Menger Sponge containing 11.9 million vertices dropped the render time to as short as 471.29 milliseconds, beating emulated calculations. The highest frame rate among the datasets was achieved with 3D Mandelbulb 200K vertex at 854 fps.\nGenerally, the performance of natively conducted double-precision computations is better on a large dataset. Though there is droppings performance in emulated computations, the native ones are much more stable. This supports that the local computations are more appropriate when working on large data sets."

Although the proposed method has much better scalability with large data sets than emulated double-precision, challenges to efficiently processing extremely large datasets may exist that decrease performance gains with dataset size. Also, the experimental results were obtained on specific hardware and software configurations and may not generalize to other systems; additional benchmarking on a diversity of configurations is thus required. Still, however illuminating the controlled setting with 2D and 3D point datasets was for this method, further testing on real-world data is required to confirm its applicability and performance in practical scenarios since different kinds of data will raise unique issues and possibly differing performance characteristics."

The results show enormous implications for data type choices, more so concerning calculation speed and processing time. Double-precision solutions have been executed on the GPU at the moment using double-float and double-double techniques. Test applications consist of 2D points and 3D points; each of them contains double-precision vertex coordinates.\nNecessary information is given in the paper hand, and experiments on using double-precision directly have been performed in the case of supporting GPU hardware. The work straight followed a method of double precision ordered by the Khronos Group in OpenGL Shading Language specification 4.5 and Vulkan specification 1.3. This is a different approach compared to traditional emulated precision methods, with no extra processing required. Although this method requires both advanced hardware and software, this is an example of the studies in scientific visualization where precision and performance are desirable together. In this work, the fundamental layer of the visualization of 2D points by uniquely generating random x and y values for these points has been addressed, and 3D points by generating from 3D mesh models with double precision x,y, and z values.\nIn the future, several experiments can be performed\u2014the ones using actual data to make the application more applicable and accurate. These datasets can be used in tests that verify the visualizing methods. In the case of successful implementation of the most straightforward building block of graphical visualization, that is, point rendering, additional visualization components can be integrated to compile a full-featured visualization library.

Then, there is a tessellation control shader that performs the division of the surface, followed by the tessellation evaluation shader, refining the vertices. Subsequently, there is a geometry shader for generating or modifying geometry. Thereafter, it proceeds to the rasterizer, which projects 3D primitives onto the 2D screen. Next up is a fragment shader to compute pixel attributes, an early depth test optimization by discarding occluded fragments, the blending stage, which combines fragment colors, among other things, for transparent effects, and an output merger that finally writes the image in the frame buffer for display.",

This finding indicates that local double-precision calculations are a more efficient option for calculations requiring high precision. While the emulation performs reasonably well at low vertex counts, local calculations are significantly faster on larger-scale datasets.

Unlike univariate cases which ignore the information, complete-multivariate models compute relationships among a complete set of features.\nHowever, despite the potential advantage of leveraging the additional information, complete-multivariate models sometimes underperform univariate ones.\nTherefore, our research aims to explore a middle ground between these two by introducing what we term Partial-Multivariate models where a neural network captures only partial relationships, that is, dependencies within subsets of all features. To this end, we propose PMformer, a Transformer-based partial-multivariate model, with its training algorithm. We demonstrate that PMformer outperforms various univariate and complete-multivariate models, providing a theoretical rationale and empirical analysis for its superiority.

+            "text": "Time-series forecasting is a fundamental machine learning task that aims to predict future events based on past observations, requiring to capture temporal dynamics. A forecasting problem often includes interrelated multiple variables (e.g., multiple market values in stock price forecasting). For decades, the forecasting task with multiple time-series features has been of great importance in various applications such as health care (Nguyen et al., 2021  ###reference_b25###; Jones et al., 2009  ###reference_b13###), meteorology (Sanhudo et al., 2021  ###reference_b29###; Angryk et al., 2020  ###reference_b2###), and finance (Qiu et al., 2020  ###reference_b27###; Mehtab, Sen, 2021  ###reference_b24###).\nFor this problem, there have been developed a number of deep-learning models,\nincluding linear models (Chen et al., 2023a  ###reference_b6###; Zeng et al., 2022  ###reference_b45###), state-space models (Liang et al., 2024  ###reference_b17###; Gu et al., 2022  ###reference_b12###), recurrent neural networks (RNNs) (Lin et al., 2023b  ###reference_b20###; Du et al., 2021  ###reference_b10###), convolution neural networks (CNNs) (Wang et al., 2023  ###reference_b34###; Liu et al., 2022a  ###reference_b21###), and Transformers (Zhou et al., 2021  ###reference_b50###; Liu et al., 2022b  ###reference_b22###). These models are typically categorized by the existence of modules that capture inter-feature information, falling into two extremes: (i) univariate and (ii) complete-multivariate models111To differentiate from existing multivariate models that capture dependencies among a complete set of features, we refer to them as complete-multivariate models, while our new approaches, which capture partial dependencies by sampling subsets of features, are termed partial-multivariate models.. While univariate models only capture temporal dependencies, complete-multivariate ones incorporate additional modules that account for complete dependencies among all given features.\nHowever, although complete-multivariate models have potential advantages over univariate ones by additionally utilizing inter-feature information, some studies have demonstrated that complete-multivariate models are sometimes inferior to univariate ones in time-series forecasting. (Zeng et al., 2022  ###reference_b45###; Zhang et al., 2023a  ###reference_b46###; Xu et al., 2024  ###reference_b41###) For example, in Table 1  ###reference_###, PatchTST (a univariate Transformer-based model) (Nie et al., 2023  ###reference_b26###) outperforms Crossformer (a complete-multivariate Transformer-based model) (Zhang, Yan, 2023  ###reference_b47###) by a large margin.\n###figure_1### Contribution.\nOur research goal is to explore a middle ground between these two extreme types, which we call a Partial-Multivariate model. Complete-multivariate models process all features simultaneously with an inter-feature module computing their complete relationships. On the other hand, typically in a univariate model, each feature is pre-processed into separate inputs, and a single neural network is shared by all features. (Nie et al., 2023  ###reference_b26###; Wang et al., 2024  ###reference_b35###; Lee et al., 2024  ###reference_b15###) In contrast to the two extreme cases, our partial-multivariate model includes a single neural network that captures dependencies within subsets of features (i.e., partial dependencies) and is shared by all sampled subsets. The differences among the three models are illustrated in Figure 1  ###reference_###.\nTo implement the concept of partial-multivariate models, we propose Partial-Multivariate Transformer, PMformer. Inspired by Nie et al. (2023  ###reference_b26###), PMformer can capture any partial relationship with a shared Transformer by tokenizing features individually and computing attention maps for selected features. Additionally, we propose training algorithms for PMformer based on random sampling or partitioning, under a usual assumption that the prior knowledge on how to select subsets of features is unavailable.\nIn experiments, we demonstrate that PMformer outperforms existing complete-multivariate or univariate models, attaining the best forecasting accuracy against 20 baselines. To explain the superiority of our partial-multivariate model against the other two types, we provide a theoretical analysis based on McAllester\u2019s bound on generalization errors (McAllester, 1999  ###reference_b23###), suggesting the following two reasons:\n(i) higher entropy in posterior distributions of hypotheses of partial-multivariate models than complete-multivariate ones and (ii) the increased training set size for partial-multivariate models against complete-multivariate and univariate ones.\nOur analysis is supported by our empirical results.\nOn top of that, to improve forecasting performance further, we introduce a simple inference technique for PMformer based on the fact that the probability that a specific event occurs at least once out of several trials increases as the number of trials gets large. Finally, we show other useful properties of PMformer: efficient inter-feature attention costs against other Transformers including inter-feature attention modules, and robustness under missing features compared to complete-multivariate models.\nTo sum up, our contributions are summarized as follows:\nTo the best of our knowledge, for the first time, we introduce the novel concept of Partial-Multivariate models in the realm of time-series forecasting, devising Transformer-based PMformer. To train PMformer, we propose a train algorithm based on random sampling or partitioning.\nThe abundant experimental results demonstrate that our PMformer achieves the best performance against 20 baselines. Furthermore, we provide a theoretical analysis for the excellence of our model and provide empirical results supporting this analysis.\nWe propose an inference technique for PMformer to enhance forecasting accuracy further, inspired by the relationships between the number of trials and probabilities of sampling a specific subset at least once. At last, we discover some useful properties of PMformer against complete-multivaraite models: efficient inter-feature attention costs and robustness under missing features."

+            "text": "To solve the forecasting problem with multiple features, it is important to discover not only temporal but also inter-feature relationships. As for inter-feature relationships, existing studies often aim to capture full dependencies among a complete set of features, which we call complete-multivariate models. For example, some approaches encode all features into a single hidden vector, which is then decoded back into feature spaces after some processes. This technique has been applied to various architectures,\nincluding RNNs (Che et al., 2016  ###reference_b5###), CNNs (Bai et al., 2018  ###reference_b3###), state-space models (Gu et al., 2022  ###reference_b12###), and Transformers (Wu et al., 2022  ###reference_b38###).\nConversely, other complete-multivariate studies have developed modules to explicitly capture these relationships. For instance,\nZhang, Yan (2023  ###reference_b47###) computes  attention matrices among  features by encoding each feature into a separate token, while Wu et al. (2020  ###reference_b39###) utilizes graph neural networks with graphs of inter-feature relationships.\nAdditionally, Chen et al. (2023a  ###reference_b6###) parameterizes a weight matrix , where each element in the -th row and -th column represents the relationship between the -th and -th features.\nUnlike complete-multivariate models which fully employ inter-feature information, new models have recently been developed: univariate models. (Zeng et al., 2022  ###reference_b45###; Xu et al., 2024  ###reference_b41###; Nie et al., 2023  ###reference_b26###; Wang et al., 2024  ###reference_b35###; Lee et al., 2024  ###reference_b15###)\nThese models capture temporal dynamics but ignore the inter-feature information by processing each of  features separately as independent inputs. It is worth noting that univariate models usually include a single neural network shared by all features.\nExisting models typically either utilize inter-feature information among all features or ignore it entirely.\nIn contrast, we propose a completely different approach to using inter-feature information, where a shared model captures relationships only within subsets of features, named partial-multivariate models."

Figure 5  ###reference_###(a) is aligned with our thought, showing monotonically decreasing test MSE as  gets large.\nIn Figure 5  ###reference_###(b), we investigate relationships between the feature subset size  and  by measuring performance gain by increasing  in various . This figure shows that the effect of increasing  tends to be smaller, as  increases. We think this is because a single subset  with large  can contain a number of features, so mutually significant features can be included in such large subsets at least once only with few repetitions.\nBesides the inference technique based on random selection, we explore another technique which samples subsets of mutually important features by selecting some keys with the highest attention scores per query. We compare this technique to the counterpart which selects keys based on the lowest attention score. In Table 4  ###reference_###, we provide the forecasting MSE of each inference technique.\n\u2014 note that only the inference method is different while the training algorithm remains the same as the original one in Algorithm 1  ###reference_###.\nIn that an inference technique utilizing the highest attention scores outperforms one with the lowest ones, attention scores are helpful in identifying relationships between features to some extent. However, our proposed method based on random partitioning achieves the best forecasting performance. Furthermore, identifying relationships between features requires high-cost attention computation which calculates full attention between  features, leading to . On the other hand, our proposed inference technique doesn\u2019t incorporate such high-cost computations but just repeats low-cost ones  times, each of which has  costs for computing inter-feature relationships \u2014 note that . In Appendix D  ###reference_###, we elaborate on the details of why PMformer achieves .\nTherefore, against the inference technique with information of attention scores, our proposed one with random partitioning is superior in terms of efficiency and forecasting accuracy.\nOther Advantages of PMformer.\nIn the real world, some features in time series are often missing. Inspired by the works that address irregular time series where observations at some time steps (Che et al., 2016  ###reference_b5###; Kidger et al., 2020  ###reference_b14###) are missing, we randomly drop some features of input time series in the inference stage and measure the increasing rate of test MSE in undropped features. For comparison, we use the original PMformer and a complete-multivariate version of PMformer (CMformer) by setting  to . PMformer can address the missingness by simply excluding missing features in the random sampling process, while CMformer has no choice but to pad dropped features with zeros. In Figure 7  ###reference_###, unlike the other case, PMformer maintains its forecasting performance, regardless of the drop rate of the features. This robust characteristic gives PMformer more applicability in real-world situations where some features are not available.\nFor Transformers with inter-feature attention modules (PMformer, Crossformer, JTFT, PETformer, and CARD), we compare the costs of their inter-feature modules using floating point operations (FLOPs) in Figure 7  ###reference_###. When na\u00efvely computing inter-feature attention like PETformer, the attention cost is  where  is the number of features. On the other hand, due to capturing only partial relationships, the attention cost of PMformer is reduced to  where  is the size of each subset. In Appendix D  ###reference_###, we elaborate on the details of the reason why the inter-feature module in PMformer achieves . Given that small  is enough to generate good forecasting performance (e.g.,  = 2030 for 300800 features), the attention cost is empirically efficient. As a result, PMformer achieves the lowest or the second lowest FLOPs compared to others, as shown in Figure 7  ###reference_###. Although Crossformer, JTFT, and CARD achieve  complexities of inter-feature attention with low-rank approximations where  is the rank, our PMformer shows quite efficient costs, compared to them."

However, most studies focus on two extremes: univariate or complete-multivariate models. To explore the middle ground between them, our research introduces a novel concept, partial-multivariate models, devising PMformer.\nPMformer captures dependencies only within subsets of a complete feature set using a single inter-feature attention module shared by all subsets. To train PMformer under usual situations without prior knowledge on subset selection, we propose a training algorithm based on random sampling or partitioning. Extensive experiments show that PMformer outperforms 20 baseline models. To explain PMformer\u2019s superior performance, we theoretically analyze the upper-bound on generalization errors of PMformer compared to complete-multivariate and univariate ones and provide empirical results supporting the results of the theoretical analysis.\nAdditionally, we enhance forecasting accuracy by introducing a simple inference technique for PMformer. Finally, we highlight PMformer\u2019s useful characteristics in terms of the efficiency of inter-feature attention and robustness under missing features against complete-multivariate models.\nLimitation. Further theoretical analysis is needed to more accurately explain partial-multivariate models, such as precisely calculating the entropy of posterior distributions and relaxing certain assumptions. Despite these limitations, our research still remains significant as it introduces the concept of partial-multivariate models for the first time and provides theoretical analyses that align with empirical results.\nBroader Impacts. Our work might have positive effects by benefiting those who devise foundation models for times series because different time series vary in the number of features and our feature sampling scheme where the sampled subset size is always  can overcome this heterogeneity. As for the negative ones, we think the negative effects of forecasting well are still under-explored."

Before getting into the main part, we define some notations. Let a neural network  be a partial-multivariate model which samples subsets  consisting of  features from a complete set of  features as defined in equation (1  ###reference_###).  denotes hypothesis class of , and  and  are a prior and posterior distribution over the hypotheses , respectively. Also,  is a input-output pair in an entire dataset and  is a pair in a training dataset  with  instances sampled from the entire dataset. At last,  is the output value of a neural network , and  and  are generalized and empirical training loss under posterior distributions  and training datasets .\nSubsequently, we list assumptions for proof:\nThe maximum and minimum values of  are known and min-max normalization is applied to  (i.e., ).\nThe output values of a neural network are assumed to be between 0 and 1, (i.e., ).\nFor posterior distributions ,  is pruned. In other words, we set  for hypotheses  where  and renormalize it.\nFor any hypothesis ,  where  is the minimum probabilities in  and .\nFor posterior distributions  and training datasets , .\nGiven that min-max normalization has been often used in time-series domains with empirical minimum and maximum values (Bhanja, Das, 2019  ###reference_b4###), Assumption 1  ###reference_umption1### can be regarded as a reasonable one. Also, by equipping the last layer with some activation functions such as Sigmoid or Tanh (hyperbolic tangent) like Xu et al. (2019  ###reference_b40###) and adequate post-processing, Assumption 2  ###reference_umption2### can be satisfied.333Assumption 1  ###reference_umption1### and 2  ###reference_umption2### can be considered somewhat strong but should be satisfied to utilize McAllester\u2019s bound widely used for estimating generalization errors (Valle-P\u00e9rez, Louis, 2020  ###reference_b32###; Amit, Meir, 2019  ###reference_b1###). When the conditions of McAllester\u2019s bound are relaxed, we can also relax our assumptions. As for Assumption 3  ###reference_umption3###, according to (McAllester, 1999  ###reference_b23###), it might have very little effects on . Finally, because Transformers can universally approximate any continuous sequence-to-sequence function (Yun et al., 2020  ###reference_b44###), (possibly, extended to general deep neural networks with the universal approximation theorem (Cybenko, 1989  ###reference_b8###)), any hypothesis  can be approximated with proper parameters in . Thus, we can assume  for any  when sampling the initial parameters of  from the whole real-number space (Assmuption 4  ###reference_umption4###). Also with proper training process and this universal approximation theorem,  might approximate to zero (Assumption 5  ###reference_umption5###). With these assumptions, the proof for Theorem 1  ###reference_orem1### is as follows:\nLet MSE be a loss function . Then, according to Assumption 1  ###reference_umption1### and 2  ###reference_umption2###,  for any data instance  and hypothesis . Then, with probability at least  over the selection of the sample  of size , we have the following for  (McAllester, 1999  ###reference_b23###):\nwhere  denotes Kullback-Leibler divergence from distribution  to . Due to Assumption 5  ###reference_umption5###, . Also, because  with Jensen\u2019s inequality and Assumption 4  ###reference_umption4###, . Therefore, we can derive Theorem 1  ###reference_orem1### by substituting  and  with  and , respectively:\n\u220e\nBased on this theorem, we provide a theoretical analysis which is the impact of  on  and . However, an additional assumption is required to make the rationale valid as follows:\nFor the region of hypothesis  where , the prior distribution satisfies  where  is small enough to be ignored in upper-bound.\nIt is possible that the upper-bound is dominated by  when . As such,  needs to be distributed properly over the region of hypothesis  where  not to result in , leading to Assumption 6  ###reference_umption6###. This assumption can be satisfied when the prior distribution is non-informative which is natural in Bayesian statistics under the assumption that prior knowledge is unknown (i.e. ). For any countable set of all possible inputs , probabilities of each  can be represented as  where  is the output of a function  under hypothesis  (Domingos, 2012  ###reference_b9###). Because  (Assumption 2  ###reference_umption2###) and  is a uniform distribution under the non-informative assumption, . As such, the prior distribution under the non-informative assumption is , leading to  which is small enough not to dominate upper-bound. On top of that, we can indirectly solve this problem by injecting appropriate inductive biases in the form of architectures or regularizers, which can help to allocate more probability to each hypothesis (i.e., increase ) by reducing the size of the whole hypothesis space .\nTo provide a proof for Theorem 2  ###reference_orem2###, we first prove Lemma 1  ###reference_ma1###. For Lemma 1  ###reference_ma1###, we need the following assumption:\nA neural network  models models  where  is an input-output pair.\nBy regarding the output of a neural network  as mean of normal or Student\u2019s -distribution like in Rasul et al. (2024  ###reference_b28###), Assumption 7  ###reference_umption7### can be satisfied. Then, Lemma 1  ###reference_ma1### and a proof are as follows:\nLet  be a training loss with posterior distributions  and a training dataset  when a subset size is . Accordingly,  with small  is a training objective. Then, for  and  where ,  satisfies both  and . (On the other hands,  is required to satisfy only .)\nLet  and  be subset size where .  be any subset of  size sampled from a complete set of features, and  is any subset of  size among ones that satisfy .  is the set of elements that are in  but not in  (i.e., ).\n is a training loss value with posterior distributions  and a training dataset  when a subset size is . Then, after training process satisfying  where  is a small value, we can say that  under  outputs the true value of , according to Assumption 7  ###reference_umption7###. In the following process, we demonstrate that  can be derived from :\nIn that expectation can be approximated by an empirical mean with sufficient data and integral can be addressed with discretization, we can think that  can be derived from . According to this fact,  under  should be able to output not only true  but also true . Therefore, we conclude that  have to satisfy both  and .\n\u220e\nWith Lemma 1  ###reference_ma1###, we provide a proof for Theorem 2  ###reference_orem2###:\nLet  be a hypothesis on a space defined when a subset size is . Then, we can denote a posterior distribution which is trained to decrease  as follows:\nAccording to Lemma 1  ###reference_ma1###, for  and  where , the posterior distributions of two cases can be represent as  and , respectively. With the following two assumptions, we can prove Theorem 2  ###reference_orem2###:\nhypotheses  and  have similar distributions after training with  (i.e., ).\nPrior distributions are nearly non-informative (i.e., ).\nAssumption 8  ###reference_umption8### can be considered reasonable because we can make the training process of a model of subset size  very similar to that of subset size  with a minimal change in architecture such as input and output masking.\nAlso, as for Assumption 9  ###reference_umption9###, non-informative prior is usually used under usual situations without prior knowledge in Bayesian statistics.\ncan be expanded as , according to Assumption 9  ###reference_umption9###. Because we exactly know whether to satisfy  given ,  is 1 when a given  satisfies  or 0, otherwise. Thus,  are defined as follows:\nSimilarly,  and  can be expanded as  and , according to Assumption 8  ###reference_umption8### and 9  ###reference_umption9###. A region of hypothesis satisfying both  and  is smaller than that satisfying either of them. Because the probability of  in a region satisfying conditions has the same value and  is maintained,  in the small region is allocated higher probabilities than  in the large one. Therefore,  and the entropy  is larger than :\n\u220e\nSo far, we have finished a proof for Theorem 2  ###reference_orem2###. We additionally provide Theorem 3  ###reference_orem3### which is a variant of Theorem 2  ###reference_orem2### where Assumption 9  ###reference_umption9### can be relaxed while proposing the relationships between  and  in the expectation level:\nfor  and  satisfying ,  in expectation over .\nLet  be the  (i.e., ).\nThen,  can be expanded as follows:\nFrom this expansion, we can derive  because entropy of  must be larger than 0 (i.e., ). By substituting  for  according to Assumption 8  ###reference_umption8### and  for , we can derive Theorem 3  ###reference_orem3###.\nAlso, based on Chebyshev\u2019s inequality, we can calculate the least probabilities at which  are satisfied, given the variance :\n\u220e"

Among Chen et al. (2023b  ###reference_b7###); Zhao et al. (2023  ###reference_b49###); Xue et al. (2023  ###reference_b42###); Gao et al. (2023  ###reference_b11###); Zhang et al. (2023b  ###reference_b48###); Shao et al. (2023  ###reference_b30###); Yu et al. (2023  ###reference_b43###); Lin et al. (2023a  ###reference_b19###); Lee et al. (2024  ###reference_b15###); donghao, xue wang (2024  ###reference_b52###); Xu et al. (2024  ###reference_b41###); Wang et al. (2024  ###reference_b35###), we select PITS, FITS, TimeMixer, JTFT, GCformer, CARD, Client, PETformer, and ModernTCN as our baselines because they have the same experimental settings with ours888We decide that it has the same experimental setting with ours when the scores of some baselines are the same. or their executable codes are available to run models in our settings.\n(1) PITS (Lee et al., 2024  ###reference_b15###): This paper proposed new a self-supervised representation learning strategy for time series with neural networks not directly considering patch-dependence. Through the contrastive learning, adjacent time series information can be captured efficiently.\n(2) FITS (Xu et al., 2024  ###reference_b41###): This paper introduced FITS, which is effective but efficient for time series tasks, based on the fact that time series can be dealt with in the complex frequency domain.\n(3) TimeMixer (Wang et al., 2024  ###reference_b35###): This paper is similar to TSMixer. However, it has distinct differences in that it utilizes a decomposition scheme and considers multi-scale time series.\n(4) JTFT (Chen et al., 2023b  ###reference_b7###): Similar to Crossformer, segmentation and two types of Transformers are employed. Before a Transformer takes input, it pre-processes input time series. It only encodes a fixed length of recent observations into tokens and sparse frequency information extracted from the whole input into tokens, rather than encodes the whole input directly. This leads to efficient self-attention for temporal dependencies. Also, with a low-rank approximation scheme, it reduces the complexity of self-attention for inter-feature dependencies.\n(5) GCformer (Zhao et al., 2023  ###reference_b49###): To overcome the limitations of Transformers that they cannot deal with long time series well, it combines a convolutional branch for global information and Transformer-based branch for local, recent information.\n(6) CARD (Xue et al., 2023  ###reference_b42###): With a dual Transformer, it can capture various dependencies across temporal, feature, and hidden dimensions. On top of that, the author devised a robust loss function to relieve overfitting issues in M-LTSF.\n(7) Client (Gao et al., 2023  ###reference_b11###): This method has two parts, one of which is a linear model to capture temporal trends and the other is self-attention for inter-feature dependencies.\n(8) PETformer (Lin et al., 2023a  ###reference_b19###): Based on Crossformer architecture, it introduced placeholder enhancement technique (PET). Thanks to PET, PETformer can forecast with only encoders (i.e., without decoder).\n(9) ModernTCN (donghao, xue wang, 2024  ###reference_b52###): Because many existing CNN-based methods don\u2019t show the good performance in time series forecasting tasks, this paper tried to modify the traditional CNNs into ModernTCN including maintaining the variable dimension, DWConv, and ConvFFN.\nAs for evaluation metrics of baseline methods, we repeat the scores when the scores of the same experimental settings as ours are available. Otherwise, we measure evaluation scores with their official codes and best hyperparameters in our experimental environments. The scores of PatchTST, FEDformer, Pyraformer, and Informer are from Nie et al. (2023  ###reference_b26###), and those of TSMixer and NLinear (DLinear) are from Chen et al. (2023a  ###reference_b6###) and Zeng et al. (2022  ###reference_b45###), respectively. Also, for PITS, FITS, TimeMixer, JTFT, GCformer, CARD, PETformer, and ModernTCN, we repeat the score reported in each paper. For Crossformer999https://github.com/Thinklab-SJTU/Crossformer  ###reference_er###, MICN, TimesNet, Client101010For MICN, TimesNet, and Client, we use the same code from https://github.com/daxin007/Client/tree/main  ###reference_in###., and DeepTime111111https://github.com/salesforce/DeepTime  ###reference_###, we measure new scores in the same experimental environments with ours.\nWhen training Crossformer, we convert a Transformer-based encoder into a linear-based encoder for fair comparison to PMformer, because the latter usually has better performance than the former.\nThe details of hyperparameters used in the PMformer are delineated in this section. The first hyperparameter is the length of input time steps . We regard it as hyperparameters which is common in recent literature for time-series forecasting (Liu et al., 2022b  ###reference_b22###; Zhang, Yan, 2023  ###reference_b47###). The range of  is {512, 1024}. Also, the number of segments  is in {8,16,32,64} and the dropout ratio  is in {0.1, 0.2, 0.3, 0.4, 0.7}. The hidden dimension  is in {32,64,128,256,512}. The number of heads in self-attention  is in {2,4,8,16} and the number of layers  is in {1,2,3}.  is the hidden size of feed-forward networks in each PMformer layer and in {32,64,128,256,512}.\nAlso, batch size is 128, 128, 16, and 12 for ETT, Weather, Electricity, and Traffic datasets, respectively. Finally, we set the learning rate and training epochs to  and 100, respectively. Finally, we use Adam optimizer to train our model. The selected best hyperparameters of PMformer are in Table 5  ###reference_###."

+    "abstract": "An avoshift is a subshift where for each set  from a suitable family of subsets of the shift group, the set of all possible valid extensions of a globally valid pattern on  to the identity element is determined by a bounded subpattern. This property is shared (for various families of sets ) by for example cellwise quasigroup shifts, TEP subshifts, and subshifts of finite type with a safe symbol. In this paper we concentrate on avoshifts on polycyclic groups, when the sets  are what we call \u201cinductive intervals\u201d. We show that then avoshifts are a recursively enumerable subset of subshifts of finite type. Furthermore, we can effectively compute lower-dimensional projective subdynamics and certain factors (avofactors), and we can decide equality and inclusion for subshifts in this class. These results were previously known for group shifts, but our class also covers many non-algebraic examples as well as many SFTs without dense periodic points. The theory also yields new proofs of decidability of inclusion for SFTs on free groups, and SFTness of subshifts with the topological strong spatial mixing property.",

+            "text": "Let  be a finite set called the alphabet and  a discrete group. A subshift of finite type or SFT  is a set closed under the shift maps , and which is defined by removing exactly the points  whose orbit hits a particular clopen set , or equivalently contain a forbidden pattern from a finite set.\nIt is well-known that one-dimensional SFTs (the case ) behave in a much nicer and uniform way than multidimensional SFTs (). As two examples of nice dynamical properties that hold in one dimension, topologically transitive subshifts of finite type in one dimension have a unique measure of maximal entropy and have dense periodic points (these fail for general subshifts of finite type, but in completely manageable ways). Furthermore, SFTs (and even their subshift factors called sofic shifts) can be algorithmically compared for equality and inclusion. See e.g. the standard reference [16  ###reference_b16###].\nIn higher dimensions, even under strong irreducibility (a strong mixing/niceness assumption), subshifts may have multiple measures of maximal entropy [7  ###reference_b7###], -SFTs are not known to have dense periodic points (see e.g. [9  ###reference_b9###]), and it is not even possible to algorithmically tell whether a given subshift of finite type is empty [4  ###reference_b4###]. For this reason, a recurring endeavor in the field of symbolic dynamics is to try to find classes of multidimensional subshifts which capture some of the interesting phenomena from the two-dimensional setting, but where at least some properties are decidable or otherwise understandable.\nGroup shifts \u2013 groups where the elements are points of the subshift, and group operations are continuous and shift-commuting \u2013 are the most successful such a class. They are of finite type when the shift group  is polycyclic [31  ###reference_b31###]. They have dense periodic points at least on abelian groups [12  ###reference_b12###]. They also of course have a \u201cmost uniform\u201d measure, namely the Haar measure. Many of their basic properties (inclusions, and even some dynamical properties) are decidable [3  ###reference_b3###]. An extensive theory of group shifts (with emphasis on the abelian case) is developed in [31  ###reference_b31###].\nIn [25  ###reference_b25###], the author introduced the so-called -TEP subshifts. They share some properties of group shifts and one-dimensional SFTs: there is a natural measure (the measure that \u201csamples patterns uniformly on convex sets\u201d). They have dense periodic points, and there are also some decidable properties, for example inclusion is easily seen to be decidable for this class.111The last results are not explicitly stated in [25  ###reference_b25###], but are obvious corollaries of results proved therein; in any case, they follow from the results proved in the present paper.\nDifferent mixing assumptions can have useful implications also in higher dimensions (even if usually not as nice as in one dimension). Strong irreducibility implies dense periodic points at least for two-dimensional SFTs [14  ###reference_b14###, 15  ###reference_b15###]. Two stronger mixing properties are the existence of a safe symbol, and the more general topological strong spatial mixing. Here, we say  is a safe symbol for an SFT  if turning a non- symbol to  in a valid configuration can never introduce a forbidden pattern, for the latter property see Definition 4.8  ###reference_###. All SFTs in these classes dense periodic points, and thus their languages and inclusion are decidable.\nIn the present paper, we define a new class of subshifts called avoshifts. This class is defined with respect to a family of subsets of the acting shift group , and the definition is that if a partial configuration  (with  in the specified class of shapes) extends to a complete configuration of the subshift, then the set of valid extensions to the identity element is determined by a finite subpattern of the configuration, which is bounded as a function of , but not necessarily .\nWe consider the class of avoshifts for a quite restricted222This is a good thing \u2013 the smaller the class of shapes, the larger the class of avoshifts. class of shapes called inductive intervals. With this choice, avoshifts generalize (cellwise quasi-)group shifts, -TEP subshifts (on  with the standard convex geometry). It also covers all SFTs with a safe symbol, and topological strong spatial mixing in fact precisely coincides with the avo property for the class of all possible shapes. Inductive intervals make sense on any polycyclic group, and depend on the chosen subnormal series.\nThe following is our main \u201cpractical\u201d result.\nLet  be polycyclic, and let  be an avoshift for inductive intervals. Then\nis of finite type,\nthe language of  can be computed algorithmically (uniformly in ),\ncan be decided for any given SFT ,\nforbidden patterns for the restrictions of  to the groups in the subnormal series (a.k.a. projective subdynamics) can be effectively computed,\n\u201cavofactors\u201d can be effectively computed,\nis uniformly SFT on inductive intervals, and the corresponding forbidden patterns can be computed, and\nwe can algorithmically semidecide that  is an avoshift from its forbidden patterns.\nAvofactors are factors that can be expressed as projections from a product that satisfies a similar property as that defining avoshifts. This includes all factors given by algebraic maps between group shifts.\nThe first five results (see below for a discussion of the sixth) were previously known for group shifts (at least for abelian groups). The first is proved in [13  ###reference_b13###, 31  ###reference_b31###] (in the former on , in the latter for general polycyclic groups), the second and third are from [12  ###reference_b12###], and the fourth and fifth are from [3  ###reference_b3###].\nAn important takeaway are that avoshifts on polycyclic groups satisfy the basic decidability properties, and SFTness, of group shifts. Notably, our proof of these results uses the group structure \u201conly once\u201d, and the only fact used is \u201cequal extension counts\u201d (see Section 3.1  ###reference_### for the definition) for all finite patterns of the same shape, which is trivially true for (cellwise quasi)group shifts. For group shifts, both [12  ###reference_b12###, 3  ###reference_b3###] strongly use Wang\u2019s algorithm [32  ###reference_b32###], which is based on the density of periodic points. Avoshifts do not have dense periodic points, and our methods are not related to Wang\u2019s algorithm in any obvious way.\nThe fact that avoshifts are of finite type does not seem to generalize beyond polycyclic groups [24  ###reference_b24###], but the other properties are really consequences of the uniform avo property (meaning the set of valid extensions of  to the identity element is determined by a subpattern which is bounded as a function of  and ), which in the case of polycyclic groups and inductive intervals is automatic. We illustrate this by giving an avoshift proof of the well-known fact that SFTs on free groups have decidable languages and decidable inclusion, by showing that SFTs are characterized by the uniform avo property on the tree convex sets from [25  ###reference_b25###].\nThe sixth property in Theorem 1.1  ###reference_### means that there is a finite set of forbidden patterns such that for  in the family, configurations that are locally legal on  are globally legal (similarly to the main property of -TEP subshifts described in the first bullet point of [25  ###reference_b25###, Theorem 1.1]). This is closely tied with the uniform avo property.\nWe also make the following two observations that may be of interest despite not having decidability implications: The topological Markov property [1  ###reference_b1###] is equivalent to being avo for the class of cofinite sets (Proposition 4.12  ###reference_###). The property of being topologically -mixing for all  can be stated equivalently as being uniformly SFT on the sets of cardinality  for all .\nA lengthy discussion of practicality of these methods, possible extensions of the theory, and future work is included in Section 10  ###reference_###."

Subsets of  are also considered as an ordered set with inclusion as the order, and  means .\nIn this paper, we use the terminology that a point is always an element of  for a group , a configuration is any element of  where  for some group  (possibly a point, possibly ), and a pattern is a configuration  whose domain  is finite. We sometimes use the term \u201cfinite pattern\u201d (meaning pattern), and \u201cpartial configuration\u201d (meaning configuration) for emphasis, and a point is sometimes referred to as a \u201ccomplete configuration\u201d. A -pattern is pattern with domain . We mostly use  to refer to points and configurations, and  to refer to patterns.\nIf  and , we write restriction as , as we tend to have non-trivial formulas for the sets  that we prefer not to have in a subscript.

We write  (and use the previous three terms as well) if  for some . We write  for the language of . Note that the empty pattern is in the language of  if and only  is nonempty.\nA subshift of finite type or SFT is  defined by , where  is clopen. A clopen set is finite union of cylinders  where  for  (the notation means finite subset). The patterns  giving the cylinders comprising  are called the forbidden patterns. A window for an SFT  is any  such that there is a set of defining forbidden patterns whose domains are contained in . A window size is any  such that  is a window. Note that on a group, we can always pick  to be the same for all the finitely many forbidden patterns, but it will be necessary later (when we later talk about being SFT on a subset of the group) to allow for the forbidden patterns to have different domains.\nIf  and  is a subshift, the -SFT approximation of  is the SFT  defined by\nEquivalently, this is the set of configurations defined by forbidding precisely the patterns  which do not appear in .\nSuppose a group  and a subshift  are clear from context. Then we say a configuration  is globally valid or globally legal if . In the case where  is an SFT, and  is a defining set of forbidden patterns, then  is locally -valid or locally -legal if no  appears in  (with  omitted if clear from context). Globally valid configurations are of course locally valid, and locally valid points (complete configurations) are globally valid.\nIf  is a subshift and  for , then the follower set  is the set of configurations  such that for some  we have , or equivalently  (and  is well-defined). We refer to configurations  as the extensions of  to . If  is a singleton (indeed even if ), we may simply write the unique element of  in this place to refer to an extension.\nWe say a subshift  is topologically mixing if for any nonempty open , for any large enough  (in word norm) there is a point  with . More generally topological -mixing means for any nonempty open  there exists  such that for any  with  for , there exists  such that  for all . In the introduction we used the term mixing/gluing property; by this we refer to notions that in some (intuitive, informal) sense generalize the idea of topological mixing.\nIf  are subshifts, a conjugacy is a shift-commuting homeomorphism , and we say  and  are conjugate in this case. A factor map is a shift-commuting continuous surjection  and we say  covers  or  is a factor of  in this case. A factor of an SFT is called sofic (note that in this paper, a factor is always a subshift).\nIf  itself is a finite group, then a subshift  is called a group shift if it is closed under the operations obtained from those of  by applying them cellwise. Group shifts are up to conjugacy the same as subshifts on which one can define a group structure by shift-invariant continuous operations [13  ###reference_b13###, 26  ###reference_b26###, 28  ###reference_b28###]. More generally, for any universal algebraic structure on , we can talk about subshifts with this structure by applying the operations cellwise."

As avoshifts have nice computational properties, no decidability-theoretically useful notion of avoshift can cover all SFTs in higher dimensions. The direction that avoshifts are SFT on the other hand generalizes to all polycyclic groups, as we will see.\nNote that the previous lemma implies that even in the case of , avoshifts need not have dense periodic points, and may have any number of measures of maximal entropy (though not in the topologically mixing case)."

Thus, this lemma indeed applies to all group shifts up to conjugacy. Quasigroup shifts are not cellwiseable [26  ###reference_b26###], so in the case of quasigroups the assumption that the alphabet itself is a quasigroup may be crucial.\nThe Ledrappier subshift\nis an abelian group shift with cellwise group operation addition in the two-element group .

Here  is the set of inductive intervals that are restricted to being negative in one axis (as we will see when we give the general definition). The proposition shows that in the two-dimensional case, this does not lead to  being an avoshift for the two-sided version of .\nHere, a cellular automaton is a shift-commuting continuous function . A neighborhood is  such that  is a function of  (which always exists by continuity). The function  is called a local rule for . A cellular automaton is reversible if it is bijective (this is equivalent to any of the following: injectivity, being a homeomorphism, or having a cellular automaton inverse ).\nLet  be a surjective cellular automaton.

The reason we include this is that in [1  ###reference_b1###] the authors are able to prove this property for abelian group shifts on many groups, and some interesting properties of group shifts can be deduced by only using the topological Markov property. Specifically, this property suffices to show some interesting measure-theoretic properties. It is a much weaker property than being SFT; even on , strong TMP subshifts need not be SFT, although they are sofic [8  ###reference_b8###], and on , there are uncountably many subshifts with strong TMP, so they are far from even being sofic. Thus one cannot expect decidability results.\nLet  be a subshift.

If there exists  such that we can always take , then  has the strong topological Markov property.\nA subshift is (uniformly) avo for the family of cofinite subsets of  if and only if it has the (strong) TMP.\nSuppose first that  is avo for the cofinite subsets.

In the case of inductive intervals on polycyclic groups, we can also compute traces (restrictions to subgroups in the subnormal series). In the next section we explain how one can also compute some factors (avofactors), which in the case of group shifts include all algebraic factors.\nA common situation in symbolic dynamics is that we are applying partial algorithms to undecidable problems, and we know that they work on some subclass of the problems, but this class itself is not obviously decidable, we usually want that our algorithm never make an incorrect claim (in addition to making correct claims on the subclass). Namely, this allows us to blindly apply our algorithms without even knowing whether they belong to the class. The algorithm is \u201callowed\u201d to work correctly even work on some instances that are not in this class, or it may never halt, it is simply not allowed to give an incorrect answer. We make this slightly more precise in the following definition.\nLet  be some countable set of (codings of) problem instances,  a subset of these instances (thought of as a nice subclass), and  the \u201cpositive instances\u201d. We say an algorithm safely partially solves  if, when given , it either eventually outputs \u201cyes\u201d, \u201cno\u201d, or never halts. Furthermore, if it says \u201cyes\u201d then , and if it says \u201cno\u201d then . We say the algorithm safely solves  on  if it safely partially solves  and, given , then it eventually gives an answer (thus indeed the correct answer) if .\nThis definition readily generalizes from decision problems to problems with more complex output (like computing the language of a subshift).\nWe define some computability properties for the sets . A family of subsets of  is upper semicomputable if we can uniformly in  compute a sequence of upper approximations to , which eventually reaches  (though we cannot necessarily detect when this has happened). We say such a family  is computable if it is also lower semicomputable, meaning we can actually compute the set of finite subsets of sets in  (note that this does not necessarily mean we can decide  for a given finite set ).\nLet  be a finitely-generated group and let  be any topologically closed family of shapes. Let  be an SFT defined by a finite set of forbidden patterns , such that  uniformly defines  on all . Then for all  there exists  such that whenever  and  is locally -valid in , then  is globally valid in .\nSuppose that the conclusion fails for some fixed . Then we can find for arbitrarily large  a shape , and a locally valid pattern  (containing no -pattern), such that  is not globally valid.\nSince  is closed, we can pass to a subsequence of  that tends to , in which case also  tends to . By compactness of Cantor space, we can find a converging subsequence of the patterns  that tends to a configuration  on  which contains no pattern from\nBy the assumption that  defines the restriction , we have . But  for large enough , a contradiction.\n\u220e\nLet  be a finitely-generated group with decidable word problem, and let  be a topologically closed, upper semicomputable, extendable family of shapes. Then there is an algorithm that, given a finite set of patterns  defining an SFT  on , enumerates all finite families of forbidden patterns  that uniformly define the -restrictions of .\nIn particular, this algorithm recognizes the SFTs that are uniformly -SFTs. Note that here we need not explicitly discuss safety; the algorithm simply will not enumerate any sets  if such sets do not exist.\nSince  is SFT and  has decidable word problem, we can compute upper approximations to the language. Note also that the equality of SFTs is semidecidable (see e.g. [29  ###reference_b29###]), so we can enumerate the complete list of sets of patterns  which define .\nThus it suffices to show that once we have found a set of patterns  equivalent to the original, which additionally defines  uniformly on , then we can recognize this fact.\nFor this, consider any such  and let  be given for  obtained from the previous lemma for the family , meaning if  is a locally -legal configuration, then  is globally legal.\nWe claim that then whenever  is -legal for , then  has a -legal extension to . Namely, otherwise every extension  is actually globally illegal. But this is a contradiction, since clearly  then already cannot be a globally valid pattern.\nThis means that we can (for the fixed ) go through larger and larger , and for fixed  we can compute better and better approximations to the set of -sized prefixes of shapes in . Since the limits of shapes from  are upper semicomputable, we eventually know the correct set of their subshapes of size at most  (though of course we cannot necessarily recognize that we do). At this point, by the assumption on  and the discussion of the previous paragraph, no matter what -legal pattern we put on one of these shapes , it will have at least one legal continuation to  that does not contain a -pattern.\nAt this point, the algorithm can conclude that  is a set of forbidden patterns defining  uniformly on . Namely, if we have a configuration on  which has no -pattern, then by -extendability of , we can order  so that prefixes of the order together with  are (up to a shift) in , and inductively prove along this order that at any point of the process there is an extension containing no pattern from .\n\u220e\nLet  be a finitely-generated group with decidable word problem, and let  be a topologically closed, upper semicomputable and extendable family of shapes. Then there is an algorithm that, given a finite set of patterns  defining an SFT  on , safely solves emptiness on all  which are uniformly SFT on . If  is constructible, it also safely solves emptiness on uniform -avoshifts .\nIf the given SFT  is empty, we can recognize this fact. Otherwise, we will try to apply the previous theorem. Since its output is correct on all SFTs (when it gives an output), if it eventually outputs some , we can determine emptiness: The empty pattern is in the language of a subshift if and only if the subshift is nonempty. Since , the only possible reason why the empty pattern would be forbidden is that the empty pattern is directly in . I.e.  is empty if and only if . If  is uniformly SFT on , then eventually we find  can can check this.\nIt suffices to show the last claim. Indeed, if  is constructible and  is a uniform -avoshift, then  is uniformly SFT on  by Lemma 5.8  ###reference_###.\n\u220e\nThe following theorem implies in particular the theorem of [3  ###reference_b3###] that projective subdynamics of group shifts on  can be computed effectively.\nLet  be a polycyclic group with polycycle structure . Then given an SFT , we can safely compute a set of forbidden patterns  that defines  uniformly on all inductive intervals if  is an II-avoshift. The restriction  is an avoshift for all . Furthermore, we can effectively compute the forbidden patterns for .\nFor the first claim, by Theorem 7.1  ###reference_###,  is uniformly SFT on iterated intervals whenever  is an II-avoshift. By Lemma 8.3  ###reference_###, we can find a set of forbidden patterns  defining it uniformly on these sets, since by Lemma 6.9  ###reference_### the II are extendable (the other properties are obvious).\nThe second claim (that  is an avoshift) is immediate from the definition.\nFor the third (decidability) claim, since each of the groups  is an iterated interval, the forbidden patterns in  that admit a translate contained in  directly define . Obviously it is decidable whether a forbidden pattern admits such a translate.\n\u220e\nThe set of II-avoshifts on a polycyclic group is recursively enumerable.\nFor each finite set of forbidden patterns defining an SFT , we try to compute forbidden patterns that define  uniformly on all inductive intervals. If we find such, then  is indeed uniformly SFT on the inductive intervals. Since the inductive intervals are a good family, Lemma 5.5  ###reference_### implies that  is (uniformly) avo on inductive intervals.\n\u220e\nNext, we proceed to show that we can compute the language of an avoshift under suitable assumptions.\nLet  be a group with decidable word problem, let  be a topologically closed, computable family of sets, and suppose that  is -constructible. Then there is an algorithm that, given a finite set of forbidden patterns  such that  defines an SFT  -uniformly, decides the language of the SFT .\nThis is a promise problem, i.e. we don\u2019t care what the algorithm does if  does not have the property stated. (But we will only apply this when we actually know  has this property.)\nOur algorithm computes better and better upper approximations to the set of patterns of  on finite subsets of  using upper semicomputability of the language.\nAt times, it will declare that it has found the precise set of patterns in the language on a particular domain. We will be sure to only add such deduction rules when they are actually safe (assuming the given property of ), i.e. when the algorithm declares it knows the patterns of a particular shape, this can be trusted to be actually true.\nTo root the process, the algorithm can check whether the empty pattern is in . If it is, then  is empty and we are done. Otherwise, it concludes that it knows the exact set of globally legal patterns on the domain  already (i.e. the empty pattern appears in the language). Also, if the algorithm has already deduced the globally legal patterns on a domain , then it knows the globally legal patterns on any , and on any subset of .\nThe crucial point is that if we know the exact patterns on  for , where  is larger than the diameter of any domain of a pattern in , then we also know the -patterns. This is because a pattern on  is in  if and only if it does not contain a -pattern, so if we know the contents of a -pattern on the annulus , then since patterns in  cannot see over the annulus, the algorithm just needs to list the possible extensions that do not directly introduce a pattern from , and these will give exactly the globally legal patterns on the extended shape.\nWe can now prove by transfinite induction on , w.r.t. the -well-order of , that the algorithm eventually knows all -shaped patterns for finite sets  whose elements are strictly below , and all their translates. (Stated like this, if the order on  has a maximum , then we do not actually deduce the finite patterns containing  directly, but any pattern can be shifted so as not to include the maximum.) For limit ordinals , the induction step is trivial. For successor ordinals, suppose  is the predecessor and let  be any finite set. It suffices to show that the algorithm eventually deduces the correct patterns on .\nBy induction, we eventually know the exact set of patterns on . If  is larger than the diameter of any pattern in  and large enough so that , then we note that by the main deduction rule, the algorithm eventually deduces the set of patterns on . After a shift, it deduces them on , and then also the subset .\n\u220e\nLet  be a finitely-generated group with decidable word problem. Let  be any algorithm that, given an SFT , safely enumerates the language of every  if  belongs to a class of subshifts . Then given SFTs , the inclusion  is safely decidable for pairs  such that .\nThe inclusion  is semidecidable. If , then there exists a pattern  such that . The latter is semidecidable. The former is semidecidable if , because eventually the algorithm  outputs the pattern . Since  outputs the language of  safely, if it outputs  then indeed , so if the deduction  is made, it is correct even if we do not necessarily have , so  is indeed decided safely.\n\u220e\nWhile the previous lemma is not commonly stated as we have here, it is well-known and commonly applied in the case that  is the class of subshifts where periodic points are dense. Namely, Wang\u2019s algorithm [32  ###reference_b32###, 29  ###reference_b29###] is more or less the proof of precisely this result. Note that here the idea of \u201csafety\u201d is quite useful \u2013 Wang\u2019s algorithm naturally allows use to conclude  for also many  where periodic points are not dense, since the algorithm that enumerates the subpatterns of periodic points indeed safely enumerates the language of a given SFT when it has dense periodic points.\nThe language of an II-avoshift on a polycyclic group is safely computable, uniformly in the SFT. In particular, given two SFTs on a polycyclic group , such that  is an II-avoshift, we can safely decide the inclusion .\nBy Theorem 8.5  ###reference_### we can safely find a set of forbidden patterns defining  uniformly on the IIs. Then we can safely compute the language by Lemma 8.7  ###reference_###. The previous lemma concludes the proof.\n\u220e\nWe recall that even in the case , the previous theorem covers some cases Wang\u2019s algorithm does not, as it does not require dense periodic points. (Similarly, Wang\u2019s algorithm covers many cases ours does not.)\nThe following is an easy exercise in automata theory, but it may be of some interest that the avoshift technology covers this.\nThe language of an SFT on the free group is decidable. In particular, given two SFTs on a free group , we can decide the inclusion .\nAs we showed in Section 4  ###reference_###, any SFT on the free group is uniformly avo on the extension set  of the limit tree convex sets . Lemma 5.8  ###reference_### says that if  is a subshift that is uniformly -avo for  with avoradius , then whenever  is -constructible,  is SFT with window size . The set  is constructible since  is a convexoid by Lemma LABEL:lem:ConvexoidConstructible.\nNext, Lemma 8.3  ###reference_### says that if  is a topologically closed, upper semicomputable, extendable family of shapes, then there is an algorithm that, given the finite set of patterns  defining an SFT  on , enumerates all finite families of forbidden patterns  that uniformly define the -restrictions of . Topological closure and upper semicomputability are clear for  from the corresponding properties of  (which are clear from the definition). Extendability follows from the proof of constructibility in Lemma LABEL:lem:ConvexoidConstructible since we can take  for some  in the proof. We conclude that such a set  exists, and thus the algorithm eventually finds one.\nNext, Lemma 8.7  ###reference_### says that if  be a topologically closed, computable family of sets, and  is -constructible, then there is an algorithm that, from such a set , decides the language of the SFT . Since the family  is guaranteed to indeed define  uniformly on , the language is decided safely for all SFTs.\nLemma 8.8  ###reference_### then implies that inclusion of SFTs is safely decidable for all SFTs, in other words the problem is simply decidable.\n\u220e"

+    "abstract": "In recent years, numerous Transformer-based models have been applied to long-term time-series forecasting (LTSF) tasks. However, recent studies with linear models have questioned their effectiveness, demonstrating that simple linear layers can outperform sophisticated Transformer-based models.\nIn this work, we review and categorize existing Transformer-based models into two main types: (1) modifications to the model structure and (2) modifications to the input data. The former offers scalability but falls short in capturing inter-sequential information, while the latter preprocesses time-series data but is challenging to use as a scalable module.\nWe propose sTransformer, which introduces the Sequence and Temporal Convolutional Network (STCN) to fully capture both sequential and temporal information. Additionally, we introduce a Sequence-guided Mask Attention mechanism to capture global feature information. Our approach ensures the capture of inter-sequential information while maintaining module scalability.\nWe compare our model with linear models and existing forecasting models on long-term time-series forecasting, achieving new state-of-the-art results. We also conducted experiments on other time-series tasks, achieving strong performance. These demonstrate that Transformer-based structures remain effective and our model can serve as a viable baseline for time-series tasks.",

In the field of time-series forecasting, its attention mechanism can automatically learn the connections between elements in a sequence, leading to widespread application (Lim et al. 2021  ###reference_b14###; Wen et al. 2022  ###reference_b27###). Informer (Zhou et al. 2021  ###reference_b34###), Autoformer (Wu et al. 2021b  ###reference_b30###), and FEDformer (Zhou et al. 2022  ###reference_b35###) are successful Transformer variants applied in time-series forecasting.\n###figure_1### Recent research (Zeng et al. 2023  ###reference_b31###) has shown that simple linear structures have outperformed previous models, challenging the effectiveness of the Transformer architecture in time-series forecasting. In response to this criticism, new paradigms have been proposed, such as iTransformer (Liu et al. 2023a  ###reference_b16###) and PatchTST (Nie et al. 2022  ###reference_b21###).\nThey demonstrate that previous models were an inappropriate use of the Transformer structure. iTransformer embeds each practice sequence into variate tokens, allowing the attention mechanism to capture multivariable correlations. PatchTST constructs novel patches, transforming the original sequence into multiple subsequences to enhance local contextual information capture. These models indicate that the Transformer structure is still effective in time-series forecasting, but the key lies in enabling the model to capture more additional information about sequences, thereby improving its representation capacity. Furthermore, most current improvements focus on modifying data input rather than making significant changes to the components of the Transformer.\nBased on capturing information between sequences and the modularization of Transformer components, we propose a new paradigm called sTransformer. Within the Transformer structure, we introduce two components: Sequence and Temporal Convolutional Network (STCN) and Sequence-guided Mask Attention (SeqMask). STCN extracts information from both the inter-sequential and temporal dimensions, allowing it to focus on relationships across different time steps and the influence of multiple variables. SeqMask enables value in attention to consider more global information. These components significantly enhance the representation capacity of the Transformer. We demonstrate the superiority of our model on several commonly used public datasets, surpassing the linear DLinear model and outperforming the latest state-of-the-art models, establishing a new SOTA for long-term time-series forecasting.\nOur work contributes as follows:\nWe constructed the STCN network structure, which uses temporal convolution to capture temporal correlations across different time steps, and inter-sequential convolution to capture correlations between sequences, thereby enhancing the representation capability of attention inputs.\nWe developed the Sequence-guided Mask attention mechanism, enabling the value layer to perform feature interactions and acquire global information.\nWe designed the highly scalable sTransformer block, integrating the STCN and SeqMask mechanisms into the Transformer structure. Multiple layers of blocks can be embedded in the framework to enhance the extraction of features from sequential and temporal dimensions."

These works can be categorized into two types: (1) modifications to the model structure and (2) modifications to the input data. In Table 1  ###reference_###, we present some of the major existing research works and compare their advantages and disadvantages.\nModels with updated components include Autoformer (Wu et al. 2021b  ###reference_b30###), Informer (Zhou et al. 2021  ###reference_b34###), FEDformer (Zhou et al. 2022  ###reference_b35###), Crossformer (Zhang and Yan 2023  ###reference_b33###). These models mainly focus on the attention mechanism\u2019s modeling of the temporal dimension and the improvement of complexity for long sequences. However, with the emergence of linear predictors (Oreshkin et al. 2019  ###reference_b22###; Zeng et al. 2023  ###reference_b31###; Das et al. 2023  ###reference_b4###), models with updated components have shown inferior performance compared to linear predictors.\nTherefore, approaches with modification to the time-series inputs emerge (Liu et al. 2022b  ###reference_b17###; Nie et al. 2022  ###reference_b21###; Liu et al. 2023a  ###reference_b16###). These models focus on the input data structure, directly or through construction, extracting the correlation information within and between sequences.\nWe believe the relatively poor performance of the first approach is not due to the component updates but rather due to the weak ability to extract correlation information between sequences. While the second approach extracts information intuitively, it has poor scalability. We believe that by designing components that can effectively extract inter-sequence correlations, we can achieve better scalability and surpass the predictive performance of the second type of method.\n###table_1###"

In recent years, some research has combined CNNs with the Transformer architecture to leverage the strengths of both, applying them to time-series problems.\nTransformer models combined with CNN primarily utilize the concept of convolution to capture local information across time steps.\nThe introduction of Temporal Convolutional Networks (TCN) (Bai, Kolter, and Koltun 2018  ###reference_b2###) architecture enhances the memory capacity for long sequences, which has led to its application in time-series task (Franceschi, Dieuleveut, and Jaggi 2019  ###reference_b6###).\nLogSparse (Li et al. 2019  ###reference_b13###) uses convolutional kernels with a stride greater than 1 when computing Query and Key, enabling the attention mechanism to focus on contextual information in the temporal dimension. Related models mainly capture local information in the temporal domain, which weakens the feature extraction capability of CNN and is the reason for the limited improvement of CNN-based Transformer. We extend the concept of convolution to inter-sequence relations, simultaneously capturing relevant information from both the temporal and inter-sequential dimensions."

This method integrates global information into the embedding and feed-forward layers through the mask.\nThere are also methods that use feature interaction to extract global information (Wang et al. 2022  ###reference_b25###). These methods have been applied in the recommendation field but, to our knowledge, have not been applied to time-series forecasting and Transformer modification. Each time-series can also be considered as an instance, so we propose a similar concept called sequence-guided mask to assist Transformer in extracting more global contextual information."

We propose sTransformer that introduces the STCN module and SeqMask mechanism to capture temporal and multivariate correlations as well as global information representation. Our model combines the strengths of various existing transformer-based models, including strong local and global information representation capabilities and high modular transferability. We conduct experiments on widely used real-world datasets in long-term time-series forecasting and achieve state-of-the-art performance, establishing a new baseline. We conduct additional experiments on short-term forecasting and anomaly detection tasks, achieving top 3 performance, which demonstrate our model\u2019s strong information extraction capabilities and generalization ability across tasks for time-series data."

+    "abstract": "This paper investigates factors related to the acceptance of trust registers (e.g., the Chinese Social Credit System \u2013 SCS) in Western settings. To avoid a negative connotation, we first define the concept of trust register which encompasses surveillance systems in other settings beyond China, such as FICO in the US. Then, we explore which factors are associated with people\u2019s attitude towards trust registers leaning on the technology acceptance and privacy concern theories. A cross-sectional survey among Slovenian Facebook and Instagram users () was conducted. Covariance-based structural equation modeling (CB-SEM) was used to test the hypothesized associations between the studied constructs. Results indicate that attitude towards trust register is directly associated with perceived general usefulness of the trust register. Additionally, perceived general usefulness is associated with perceived usefulness of the trust register for ensuring national security and fighting crime, its ease of use, and privacy concern regarding data collection. As one of the first studies investigating attitude towards trust registers in a Western country, it provides pioneering insights into factors that may be relevant in case such registers would be implemented in a Western context, and provides some practical implications regarding messaging for would-be implementers of such systems.",

+            "text": "The Social Credit System (SCS) developed in China is a widely discussed topic in the global community (Vasilyeva et al., 2020  ###reference_b53###). Human rights advocates, government officials, and scholars of various specializations have taken an increasing interest in this phenomenon (Bach, 2020  ###reference_b5###; Vasilyeva et al., 2020  ###reference_b53###; Kostka, 2019  ###reference_b27###; Ma, 2019  ###reference_b34###; Rieger et al., 2020  ###reference_b43###; Mac S\u00edthigh and Siems, 2019  ###reference_b36###; Ahmed, 2017  ###reference_b2###; Ohlberg et al., 2017  ###reference_b40###). However, despite a high public profile, this problem is scientifically still poorly understood (Vasilyeva et al., 2020  ###reference_b53###).\nThe emerging SCS in China stands out as an initiative to radically transform society and the economy in the country (Bach, 2020  ###reference_b5###), with a desire to take even greater control of its population and other entities. The system is envisioned to rate individuals, businesses, social organizations, and government agencies based on their level of trustworthiness, and aims to be administered through various systems of punishments and rewards (Kostka, 2019  ###reference_b27###; Lin and Milhaupt, 2023  ###reference_b33###). One of the more controversial features of this system is that it requires large amounts of personal data and information on each individual to function, which is collected from a variety of sources, such as financial, criminal, and government records, as well as various data from registry and school offices (Backer, 2019  ###reference_b6###; Ma, 2019  ###reference_b34###; Li, 2023  ###reference_b31###). Notably, it also tracks subjects\u2019 activities online by including various data from digital sources (Backer, 2019  ###reference_b6###; Ma, 2019  ###reference_b34###). Digital data includes information collected on the internet, such as a person\u2019s online search history, shopping preferences, and social media interactions (Ma, 2019  ###reference_b34###), control of which represents an intrusion into an individual\u2019s privacy (Li et al., 2022  ###reference_b32###). In the future, the system could also include video system information obtained with facial recognition technology which is already widespread in China (Backer, 2019  ###reference_b6###) coupled with techniques, for example, for image superresolution (i.e., the process of enlarging and enhancing low-resolution images) (Kumar and Jain, 2022  ###reference_b29###) and age estimation (Grd et al., 2023  ###reference_b21###), applications of artificial intelligence (Zekan et al., 2022  ###reference_b63###), integration with VoIP mass surveillance systems (Mathov et al., 2022  ###reference_b38###), or data obtained from smart systems, such as smart transportation (Benyahya et al., 2022  ###reference_b7###). The development of the SCS itself is still ongoing so it cannot exactly be described as a single system (Vasilyeva et al., 2020  ###reference_b53###; Kostka, 2019  ###reference_b27###; Von Blomberg, 2023  ###reference_b56###). For the time being, it is only an attempt to bring together different national, provincial, and municipal testing systems which focus on entirely different policies and issues (Backer, 2019  ###reference_b6###; Wang et al., 2023  ###reference_b59###). This means that they do not have the same goal therefore the system cannot yet be unified. However, what all different SCS initiatives have in common is that they all seek to control through the establishment of a distributed state surveillance system fit for the current digital age and facilitate the rise of the digital society and cybernetic citizenship (Hansen, 2023  ###reference_b22###; Reijers et al., 2023  ###reference_b42###; Trauth-Goik, 2023  ###reference_b51###).\nSuch systems of control are not specific only for China, though (Wang et al., 2023  ###reference_b59###). Different systems of control exist in other countries, such as Germany and the US, too, although that does not mean that they are socially recognized as such as well since they focus on the financial aspect (Yin and Song, 2023  ###reference_b62###). Schufa in Germany and EDGAR in the US are two examples of nationwide public platforms disclosing corporate information on listed companies (Krause et al., 2023  ###reference_b28###). Among the best-known systems for individuals is the US FICO which indicates the creditworthiness of a particular individual (Ignatius et al., 2018  ###reference_b25###) and is used by 75 percent of lenders in the US (Hendricks, 2011  ###reference_b23###). It was developed around 1950 (Doroghazi, 2020  ###reference_b17###) and officially came into use in 1989 (Ignatius et al., 2018  ###reference_b25###). It is a system that evaluates whether or not an individual is creditworthy based on a credit score (Hendricks, 2011  ###reference_b23###; Ignatius et al., 2018  ###reference_b25###; Arya et al., 2013  ###reference_b4###). According to this system, the higher the score, the higher the level of creditworthiness (Brevoort et al., 2016  ###reference_b8###). The system uses five different factors (Chatterjee et al., 2005  ###reference_b9###; Demyanyk, 2010  ###reference_b15###), but the exact formula for calculating an individual\u2019s creditworthiness is not publicly known (Hendricks, 2011  ###reference_b23###; Arya et al., 2013  ###reference_b4###; Demyanyk, 2010  ###reference_b15###). Banks use such systems to protect themselves from untrustworthy individuals making it easier for them to increase their profits (Stewart, 2011  ###reference_b48###). A good way to predict an individual\u2019s actions is to evaluate their past (Doroghazi, 2020  ###reference_b17###; Demyanyk, 2010  ###reference_b15###). The credit score is based completely on the information contained in the credit report (Hendricks, 2011  ###reference_b23###) so the information obtained and processed must be correct. Numerous cases have shown that errors still occur in the processing of data (e.g., mistaken social security number, bankruptcy error) (Hendricks, 2011  ###reference_b23###; Brevoort et al., 2016  ###reference_b8###) with individuals being severely affected as the errors impact their creditworthiness (Arya et al., 2013  ###reference_b4###). To have a credit score, an individual must have at least one credit card or one loan, and if an individual does not have them, banks do not have enough information to calculate their credit score (Elliott et al., 2018  ###reference_b18###). A 2016 survey found that approximately 45 million people in the US do not have a credit score (Brevoort et al., 2016  ###reference_b8###). The consequences of a poor or undefined credit score significantly impact an individual\u2019s life and functioning in society, as they consequently have limited access to financial assistance (Elliott et al., 2018  ###reference_b18###; Brevoort et al., 2016  ###reference_b8###). Even when borrowing money, they are charged the highest possible interest rates which has a direct impact on their lives and their ability to save and improve their living situation (Elliott et al., 2018  ###reference_b18###; Brevoort et al., 2016  ###reference_b8###).\nBoth the Chinese SCS and comparable systems in other countries measure the level of trust of an individual and thus influence the individual\u2019s social functioning. To the best of our knowledge, the general concept of such surveillance systems has not been defined before. For the purpose of our study, we define the trust register as an official register that can be introduced at the state level to monitor, assess and regulate the financial, social, moral and political behavior of natural and legal persons through a system of penalties and rewards. Trust registers provide various benefits to trusted people (e.g., tax breaks, easier access to loans and housing, cheaper public transport, shorter waiting times for health-related services, the possibility of renting a car without providing a security deposit) and through various penalties (e.g., tougher access to loans, limited access to public services, prohibition to perform state jobs, harder access to education) to encourage untrustworthy people to improve (Von Blomberg and Reijers, 2023  ###reference_b57###). Trust registers draw information from a variety of traditional (e.g., financial, criminal, and state records, registry and school office data) and digital sources (e.g., online search history, online shopping history, social media activities) (Li, 2023  ###reference_b31###). The data is accumulated into trust registers and processed automatically (Yin and Song, 2023  ###reference_b62###). The use of trust registers may be possible through a mobile application that allows individuals and organizations to see the level of trustworthiness of others, for example, online stores and potential customers. Everyone may quickly find out whether or how he wants to establish contact or do business with natural and legal persons whom he does not know yet or has no experience with (Von Blomberg and Yu, 2023  ###reference_b58###).\nA few studies have explored public opinion on SCS in China by examining citizens\u2019 attitudes toward the system and their privacy concerns (Kostka, 2019  ###reference_b27###; Rieger et al., 2020  ###reference_b43###; Ahmed, 2017  ###reference_b2###; Ohlberg et al., 2017  ###reference_b40###). Published literature suggests that SCS receives high levels of support among Chinese citizens which could be attributed to the lack of knowledge about the system (Xu et al., 2023  ###reference_b61###). Studies also indicate that support is correlated with one\u2019s generalized fear (Zeng and Wong, 2023  ###reference_b64###). On the organizational level, the use of SCS has also been associated with innovation (Zuo et al., 2023  ###reference_b65###). However, there is a general lack of research that would investigate individuals\u2019 attitudes towards such surveillance systems outside of China. We found a single study, conducted in China, that indicates that public support for SCS may be lower when exposed to Western framing albeit only when individuals are informed about the monitoring of social behavior by SCS (Xu et al., 2023  ###reference_b61###). Therefore, it might be safe to assume that such surveillance systems may not be as well-received in Western countries even though comparable systems are already in place there. To the best of our knowledge, there are no studies that would explore the factors associated with attitudes, adoption or rejection of trust registers outside of China.\nThis paper aims to address the above presented gaps in our understanding of what shapes one\u2019s attitude toward trust registers. This study makes four key contributions. First, this study defines the concept of trust register as an umbrella term for surveillance systems. Second, by considering trust registers as a technological innovation leveraged by a state for surveillance, our study leans on the technology acceptance theory to explore factors associated with attitude towards trust registers contributing to both state data surveillance and technology acceptance theory. Third, it is among the first to study how online privacy concerns are related to attitude towards trust registers contributing to the privacy concerns literature. Fourth, this study provides some insights into acceptance factors for implementations of trust registers with broadened scopes in Western countries."

+            "text": "The study aims to investigate the main factors that would positively or negatively influence attitude toward trust registers. For this research, we have built a research model based on the hypotheses we have put forward. The model shows us the factors that we assume will have the most significant relations with attitude towards trust registers. The research model is presented in Figure 1  ###reference_###.\n###figure_1### How individuals would accept the use of new technology can be tested using the Technology Acceptance Model (TAM) (Davis, 1989  ###reference_b13###). The original TAM is based on two main predictors (i.e., perceived usefulness and perceived ease of use) of attitude towards use of new technology (Davis, 1989  ###reference_b13###). Perceived usefulness measures the extent to which a person believes that using a new technology will increase their performance and gain benefits (Venkatesh and Davis, 2000  ###reference_b54###). Perceived ease of use however helps us to determine the extent to which a person believes that they would be able to use the new technology effortlessly and that it would be easy to use (Davis, 1989  ###reference_b13###). In other words, the more benefits the user gets and the easier new technology is to use, the more likely individuals will support it and be willing to use it (Alassafi, 2022  ###reference_b3###). Based on the original TAM model, we therefore formulate the following hypotheses:\nPerceived usefulness of the trust register is positively associated with attitude towards trust register.\nEase of use of the trust register is positively associated with attitude towards trust register.\nEase of use of the trust register is positively associated with perceived usefulness of the trust register.\nPerceived usefulness can be measured by various indicators, such as speed of achievement, increased productivity, efficiency, etc. (Warkentin et al., 2007  ###reference_b60###). In the context of trust registers, there are two key benefits that are emphasized by their implementers, namely ensuring national security and fighting crime. For the purpose of our study, we assume these two dimensions of perceived usefulness shape the perceived general usefulness of trust registers. Based on these considerations, we develop the following set of hypotheses:\nPerceived usefulness of the trust register for ensuring national security is positively associated with perceived general usefulness of the trust register.\nPerceived usefulness of the trust register for fighting crime is positively associated with perceived general usefulness of the trust register.\nInformation privacy pertains to an individual\u2019s capacity to personally manage the information concerning their identity (Stone et al., 1983  ###reference_b49###). When discussing measuring privacy concerns, we can divide them into five different dimensions (Smith et al., 1996  ###reference_b47###; Van Slyke et al., 2006  ###reference_b52###; Fortes and Rita, 2016  ###reference_b19###; Pu et al., 2022  ###reference_b41###). First, concern regarding data collection is connected with the collection and storage of personal data in a certain system. Second, concern regarding secondary use of data is about the use of stored data in a certain system for a different purpose than it was collected for. Third, concern regarding improper access is related to data stored in a certain system being accessed by unauthorized persons. Fourth, concern regarding errors is linked to errors in collected data stored in a certain system. Fifth, concern regarding control is connected with (the lack of) control that individuals have over their collected data stored in a certain system. People who worry more about their privacy may therefore feel mentally burdened when they need to share their personal data with trust registers decreasing their motivation to engage with such systems (Davis et al., 1992  ###reference_b14###; Fortes and Rita, 2016  ###reference_b19###). However, such feelings have a negative impact on perceived usefulness (Fortes and Rita, 2016  ###reference_b19###), and individuals will be less likely to use technology that lowers their expectations of privacy (Dhagarra et al., 2020  ###reference_b16###). Based on the privacy literature, we thus pose the following set of hypotheses:\nPrivacy concern about data collection is negatively associated with perceived usefulness of the trust register.\nPrivacy concern about secondary use of data is negatively associated with perceived usefulness of the trust register.\nPrivacy concern about improper access to data is negatively associated with perceived usefulness of the trust register.\nPrivacy concern about data errors is negatively associated with perceived usefulness of the trust register.\nPrivacy concern about data control is negatively associated with perceived usefulness of the trust register.\nTrust may equal power and can therefore be valuable in many interactions. Establishing trust is a long process as it develops over a long period of time, but can be lost in an instant (Tolbert and Mossberger, 2006  ###reference_b50###). Trust is a psychological state in which an individual is willing to acknowledge, accept, or show their vulnerability to a particular individual or the public at large because they expect positive intentions from the other party (Cullen and Reilly, 2008  ###reference_b11###). Trust also has a strong influence on the performance of governments (Colesca, 2009  ###reference_b10###). Studies show that in modern democracies citizens\u2019 distrust of their government can have a negative impact on its performance (Nasser et al., 2020  ###reference_b39###). Our trust in institutions is conditioned by our expectations, knowledge of their functioning and intentions, and the competence of the individuals who work within them (Colesca, 2009  ###reference_b10###). The greater the trust in government, the more willing citizens are to engage with it (Tolbert and Mossberger, 2006  ###reference_b50###). Citizen engagement with government is necessary because government institutions and agencies need personal data to operate, which they collect and process (Nasser et al., 2020  ###reference_b39###) to ensure the proper functioning of government systems such as e-government, healthcare, etc. Providing personal data to government organizations is therefore absolutely necessary in many cases (Cullen and Reilly, 2008  ###reference_b11###). So it makes it all the more important that government and government organizations handle sensitive information correctly and use the data only for the purposes for which it is collected (Nasser et al., 2020  ###reference_b39###). Individuals who do not trust the government and its performance are skeptical about participating (Cullen and Reilly, 2008  ###reference_b11###) in different surveillance systems, including trust registers. Based on this, we developed the final hypothesis:\nTrust in government is negatively associated with attitude towards trust register.\nThe research model therefore draws from the technology acceptance, privacy concern and trust theories, and tries to draw synergies in explaining how attitudes towards trust registers are formed."

It is also among the first such studies focusing on a population outside China. It makes a number of contributions to the literature on attitudes toward state data surveillance, technology acceptance and privacy concerns, and provides some practical implications regarding messaging for would-be implementers of such systems in Western contexts. First, this study defines the concept of trust register as an umbrella term for surveillance systems comparable to the SCS. SCS and comparable systems in the West are essentially registers in which data are accumulated and processed to determine an individual\u2019s or other entity\u2019s trustworthiness score. The aim of defining a new neutral concept instead of focusing the study on SCS was to avoid the effect of the potential negative connotation that SCS may have in Western countries, such as Slovenia. Although studies focusing on SCS may have some merit in Western countries too, the negative connotation due to the Western media exposure and the fact that SCS originates from China may affect the validity of such studies. Therefore, the implications of such studies might have little relevance for potential implementations of SCS-like systems in Western countries. Since trust registers encompass both SCS and other surveillance systems, using this concept may enable researchers to study the impact of such (non-)negative connotations of both SCS and other comparable systems.\nSecond, this is one of the first studies to investigate which factors are associated with attitude towards trust register. The results of our study indicate that the associations based on the original TAM have merit in the context of our study. More specifically, perceived usefulness is directly associated with attitude towards trust registers. Even though ease of use was not directly related to attitude towards trust register as predicted by the original TAM, there is an indirect relation mediated by perceived usefulness as predicted by the original TAM (Maranguni\u0107 and Grani\u0107, 2015  ###reference_b37###). We additionally found that perceived general usefulness is associated with both perceived usefulness of the trust register for ensuring national security and fighting crime. These findings indicate that these often emphasized SCS goals are indeed relevant in shaping the attitude towards trust register and thus effective in promoting SCS to the public. Although trust registers are enabled and may be ultimately controlled by governments, trust in government was not associated with attitude towards trust register. This may be a consequence of the study settings since it was conducted in a Western democracy as countries vary considerably according to their residents\u2019 surveillance concern, fear of government intrusions into privacy and trust in government (Fujs and Vrhovec, 2019  ###reference_b20###). Future studies in other countries around the globe (e.g., autocratic regimes) would be necessary to determine whether there are significant differences in other political contexts.\nThird, the results of our study indicate that privacy concern about data collection is indirectly associated with attitude towards trust register through perceived usefulness. Although the published literature emphasizes privacy concern of citizens due to the overreaching nature of trust registers (Kostka, 2019  ###reference_b27###; Rieger et al., 2020  ###reference_b43###; Ahmed, 2017  ###reference_b2###; Ohlberg et al., 2017  ###reference_b40###), this is one of the first studies that empirically test these assumptions. The results of this study suggest that only one out of five tested dimensions of privacy concern is associated with attitude towards trust register. These findings is therefore only partially in line with the published SCS literature as respondents seem to associate only data collection with their attitude toward trust register, and not other privacy-related issues, such as errors in collected data, secondary use of the data, improper access to the data (e.g., by hackers) or the lack of control over collected data. Nevertheless, this may be yet another example of the privacy paradox according to which people engage in privacy infringing behavior despite voicing concern about it (Lenz et al., 2023  ###reference_b30###).\nFourth, the results of this study provide some insights into the possible implementation of trust registers in Western countries. As already noted, trust registers are not unheard of in these countries (e.g., EDGAR, Schufa, FICO (Krause et al., 2023  ###reference_b28###; Ignatius et al., 2018  ###reference_b25###)). However, these systems focus solely on the financial aspect (Yin and Song, 2023  ###reference_b62###). Even though Western trust registers are not associated with the social aspect of surveillance, surveillance of social media data is extensive in Western countries too (Schyff et al., 2020  ###reference_b44###; Selvarajah and Nawarathna, 2022  ###reference_b45###). The results of our study provide some insights into acceptance factors for potential implementers of trust registers with broadened scopes (e.g., the social aspect) in Western countries. Messaging regarding the implementation of a trust register with a broadened scope may focus on its perceived usefulness. The results of our study suggest that perceived general usefulness of trust registers may be shaped by its ease of use and usefulness for ensuring national security and fighting crime. Key messaging points could therefore focus on these topics to shape an adequate attitude towards trust register. These topics are already ingrained in Western societies as acceptable reasons for exchanging privacy for security (Da Silva, 2022  ###reference_b12###). Additionally, the results of our study indicate that messaging aiming to relieve the privacy concern may primarily focus on alleviating people\u2019s concern regarding the collection of data. These practical implication should however be taken with some reserve as it assumes that the target population does not associate such a trust register with SCS or similar systems. Should the population relate the implementation of a trust register to the implementation of a controversial surveillance system, the negative connotation of such a trust register might significantly alter acceptance factors. Future studies, such as those focusing on a potential implementation of a SCS-like surveillance system in the West, may be needed to estimate the extent of these changes.\nThis study has some limitations that the readers should note. First, the sample is not representative therefore the readers should be careful when generalizing the results to the studied population. Future studies may aim to include respondents that were underrepresented in our sample, notably people whose primary source of information is not the internet. Data collection methods beyond online surveys may be employed to achieve these aims. Second, the study was conducted in a single Western country. For improving the ecological validity of the study, future studies may focus on other countries in the Western cultural context, too. To better understand the differences between the Eastern and Western cultural contexts as well as in countries with varying surveillance concerns (Fujs and Vrhovec, 2019  ###reference_b20###), comparative studies would be highly beneficial as well. Third, the study described trust registers to the respondents without providing them with any real-world examples of such registers. Although the description was based on the SCS, the respondents may not have grasped all implications of implementing trust registers on a large scale. Future studies focusing on existing trust registers, such as SCS, EDGAR, Schufa or FICO, or implementations of other pilot trust registers, perhaps for the sole purpose of conducting experiments, may thus be beneficial. Fourth, this study focused on attitude towards trust register. Attitude is an important albeit not the only acceptance factor. Future studies may include other acceptance factors, such as social influence, in their investigations. However, the role of some of these factors may be hard to study without actual trust register implementations. Additionally, studying factors associated with actual acceptance in pilot implementations of trust registers would be highly beneficial. Finally, our study focused on individuals. Trust registers can be used for both individuals and organizations. Therefore, future studies may explore the factors associated with acceptance of trust registers by organizations."

+    "abstract": "Few-shot object counting has garnered significant attention for its practicality as it aims to count target objects in a query image based on given exemplars without the need for additional training.\nHowever, there is a shortcoming in the prevailing extract-and-match approach: query and exemplar features lack interaction during feature extraction since they are extracted unaware of each other and later correlated based on similarity. This can lead to insufficient target awareness of the extracted features, resulting in target confusion in precisely identifying the actual target when multiple class objects coexist. To address this limitation, we propose a novel framework, Mutually-Aware FEAture learning (MAFEA), which encodes query and exemplar features mutually aware of each other from the outset. By encouraging interaction between query and exemplar features throughout the entire pipeline, we can obtain target-aware features that are robust to a multi-category scenario. Furthermore, we introduce a background token to effectively associate the target region of query with exemplars and decouple its background region from them. Our extensive experiments demonstrate that our model reaches a new state-of-the-art performance on the two challenging benchmarks, FSCD-LVIS and FSC-147, with a remarkably reduced degree of the target confusion problem.",

+            "text": "Object counting has achieved remarkable advances along with deep learning networks.\nHowever, most existing object counting methods are designed for a limited number of categories such as human macrowd or car car2.\nIn fact, those methods highly rely on a large amount of labeled data and cannot handle unseen categories beyond training data.\nIn this regard, few-shot object counting Lu et al. (2019  ###reference_b14###) has been proposed to count arbitrary class objects in a query image based on the given exemplar images.\nA mainstream of few-shot object counting is the extract-and-match approach Lu et al. (2019  ###reference_b14###); Yang et al. (2021  ###reference_b26###); Ranjan et al. (2021  ###reference_b18###); Shi et al. (2022  ###reference_b19###); Gong et al. (2022  ###reference_b7###); You et al. (2023  ###reference_b28###); Lin et al. (2022  ###reference_b12###); Liu et al. (2022  ###reference_b13###); Djuki\u0107 et al. (2023  ###reference_b4###); Gao and Huang (2024  ###reference_b6###).\nGenerally, this pipeline consists of three key components: 1) feature extractor, 2) relation learner, and 3) decoder.\nFirstly, they compute query and exemplar features using the feature extractor, then construct the correlation volume through the relation learner.\nAfterward, they estimate the number of instances in the query image by transferring the correlation volume to the decoder.\n###figure_1### Although previous studies You et al. (2023  ###reference_b28###); Djuki\u0107 et al. (2023  ###reference_b4###) have achieved impressive performance, they exhibit a target confusion issue, failing to accurately identify only the target class when multiple classes of objects coexist in the query image, as shown in Figure 1  ###reference_###.\nExisting methods have overlooked this problem, which is directly connected to the purpose of few-shot object counting, as benchmark datasets such as FSC-147 Ranjan et al. (2021  ###reference_b18###) primarily consist of single-class scenes.\nThe main reason for the target confusion is that the query features are computed without any explicit guidance of the target class.\nConsequently, the query features tend to focus on objectness rather than target class-specific features, hindering the differentiation between target and non-target object features.\nTo address this, we propose a novel framework, Mutually-Aware FEAture Learning (MAFEA), which enables the early consideration of mutual relations between query and exemplar features to produce the target class-specific features.\nSpecifically, MAFEA employs cross-attention to capture bi-directional co-relations between query and exemplar features, along with self-attention to reflect internal relationships.\nWith the cross-attention operating in a unified embedding space, the model can identify the difference between the target and non-target object features based on the exemplar features.\nHowever, in the cross-attention, query background features including non-target object features are inherently expressed by exemplar features since there are no other features except exemplar features.\nThis might blur the distinction between the target and background features.\nTo prevent this, we introduce a background token, which is incorporated alongside exemplar features in both self- and cross-attentions.\nThis token is trained by our newly proposed Target-Background Discriminative (TBD) loss to effectively represent background features, including non-target object features.\nConsequently, MAFEA can capture the mutual relations beginning from the feature extractor and recognize the target objects clearly in the multi-category scenario as shown in Figure 1  ###reference_###.\nTo sum up, our contributions are as follows:\nTo our knowledge, our approach is the first to tackle the target confusion issue, which involves accurately identifying the target class in a multi-class scenario.\nWe propose a novel framework, Mutually-Aware FEAture Learning, which considers the mutual relationship between query and exemplar features from the outset.\nWe introduce the background token and the Target-Background Discriminative loss to ensure a clear distinction between target and background representation.\nOur method achieves state-of-the-art performance over baselines, and its effectiveness in a multi-class scenario is validated through comprehensive experiments."

This novel method allows users to effortlessly guide image generation via mouse trajectories. To achieve precise control, we design a distance awareness energy function to effectively guide latent variables, ensuring that the focus of generation is within the areas defined by the trajectory. The energy function encompasses a control function to draw the generation closer to the specified trajectory and a movement function to diminish activity in areas distant from the trajectory. Through extensive experiments and qualitative assessments on the COCO dataset,\nthe results reveal that TraDiffusion facilitates simpler, more natural image control. Moreover, it showcases the ability to manipulate salient regions, attributes, and relationships within the generated images, alongside visual input based on arbitrary or enhanced trajectories.

+            "text": "###figure_1### Over the past few years, the field of image generation has experienced remarkable progress, particularly with the development of models (Goodfellow et al. 2020  ###reference_b10###; Ho, Jain, and Abbeel 2020  ###reference_b12###; Rombach et al. 2022  ###reference_b39###; Saharia et al. 2022  ###reference_b42###; Ramesh et al. 2022  ###reference_b36###) trained on large-scale datasets sourced from the web. These models, particularly those that are text conditioned, have shown impressive capabilities in creating high-quality images that align with the text descriptions provided (Dhariwal and Nichol 2021  ###reference_b6###; Song, Meng, and Ermon 2020  ###reference_b44###; Isola et al. 2017  ###reference_b18###; Song et al. 2020  ###reference_b45###). However, while text-based control has been beneficial, it often lacks the precision and intuitive manipulation needed for fine-grained adjustments in the generated images. As a result, there has been growing interest in exploring alternative conditioning methods (Li et al. 2023  ###reference_b25###; Nichol et al. 2021  ###reference_b29###; Zhang et al. 2020  ###reference_b62###; Zhang, Rao, and Agrawala 2023  ###reference_b63###), such as edges, normal maps, and semantic layouts, to offer more nuanced control over the generated outputs. These diverse conditioning techniques broaden the scope of applications for generative models, extending from design tasks to data generation, among others.\nTraditional methods (Zhang, Rao, and Agrawala 2023  ###reference_b63###; Kim et al. 2023  ###reference_b21###) with conditions such as edges, normal maps, and semantic layouts can achieve precise object shape control, while box-based methods enable coarse layout control. However, we find that trajectory-based control aligns more closely with actual human attention (Xu et al. 2023  ###reference_b54###; Pont-Tuset et al. 2020  ###reference_b32###), and provides a level of control granularity between the fine mask and the coarse box, as shown in Figure 1  ###reference_###.\nTherefore, in parallel with these traditional layout control methods, this paper proposes a trajectory-based approach for text-to-image generation to fill this gap.\nThe central challenge we address is the utilization of trajectory to control image generation. Several studies (Hertz et al. 2022  ###reference_b11###; Kim et al. 2023  ###reference_b21###; Chen, Laina, and Vedaldi 2024  ###reference_b5###) have successfully manipulated images by adjusting attention maps in the text-related cross-attention layers on the stable diffusion models (Rombach et al. 2022  ###reference_b39###), achieving effective control without additional training\u2014a notably convenient approach. A standout method (Chen, Laina, and Vedaldi 2024  ###reference_b5###) among these, known as backward guidance, indirectly adjusts the attention by updating the latent variable. This technique, compared to direct attention map manipulation, yields images that are smoother and more accurately aligned with intended outcomes. It capitalizes on the straightforward nature of box-based conditioning, which effectively focuses attention within a specified bounding box region and minimizes it outside, enhancing the relevance of generated content. However, given the inherently sparse nature of trajectory-based control, applying backward guidance in this context poses significant challenges, requiring innovative adaptations to harness its potential effectively.\nIn this paper, we propose a novel training-free trajectory-conditioned image generation method. This technique enables users to guide the positions of image elements described in text prompts through trajectories, significantly enhancing the user experience by providing a straightforward way to control the appearance of generated images. To enable effective trajectory-based control, we introduce a distance awareness energy function. which updates latent variables, guiding the target to exhibit a stronger response in regions closer to the specified trajectory. The energy function comprises two main components: a control function, which directs the target towards the trajectory, and a movement function, which reduces the response in irrelevant areas distant from the trajectory.\nOur trajectory-based approach offers a promising solution for layout-controlled image generation. Via qualitative and quantitative evaluations, we demonstrate the superior control capabilities of our method, achieving remarkable improvements in both the quality and accuracy of generated images. Moreover, our method exhibits adaptability to arbitrary trajectory inputs, allowing for precise control over object attributes, relationships, and salient regions."

One prominent approach within this paradigm is the Stable Diffusion Model (SDM) (Rombach et al. 2022  ###reference_b39###), which enhances the fidelity and stability of image generation.\nThe SDM is distinguished by its iterative denoising process initiated from a random noise map. This method, often performing in the latent space of a Variational AutoEncoder (VAE) (Kingma and Welling 2013  ###reference_b22###; Van Den Oord, Vinyals et al. 2017  ###reference_b49###), enables the generation of images that faithfully captures the semantics conveyed in the input text. Notably, SDMs leverage pretrained language models (Radford et al. 2021  ###reference_b35###) to encode textual inputs into latent feature vectors, facilitating efficient exploration of the image manifold.\nWhile image diffusion models excel in synthesizing images from textual prompts, accurately conveying all details of the image remains a challenge, particularly with longer prompts or atypical scenes. To address this issue, recent studies have explored the effectiveness of classifier-free guidance (Ho and Salimans 2022  ###reference_b13###). This innovative approach enhances the faithfulness of image generations by providing more precise control over the output, thereby improving the alignment with the input prompt."

These methods leverage large pretrained diffusion models and allow users to specify spatial conditions such as Canny edges, Hough lines, user scribbles, human key points, segmentation maps, shape normals, depths, cartoon line drawings and bounding boxes to define desired image compositions.\nHowever, the advancement of spatially controlled image generation models have also brought significant training costs, stimulating the development of a range of training-free layout control and image editing methods (Hertz et al. 2022  ###reference_b11###; Xie et al. 2023  ###reference_b53###; Kim et al. 2023  ###reference_b21###). These approaches leverage the inherent capabilities of cross-attention layers found in state-of-the-art diffusion models, which establish connections between word tokens and the spatial layouts of generated images. By exploiting this connection, these methods enable effective spatial control over the image synthesis process without the need for specialized training procedures."

These methods directly affect the prior structure of the generated object in the image.

We first evaluate the Stable Diffusion model (Rombach et al. 2022  ###reference_b39###) for reference. We consider the prior structure based guidance as the baseline, and a method of expanding to the fixed size outwards along the trajectory to obtain a mask is also compared. Then we experiment with only the control function to validate the controllability, and further add the movement function to verify that the method is able to suppress the response of object at the irrelevant regions far from the trajectory.\nThe results are shown in Table 1  ###reference_###. We can observe that the prior structure based guidance and the trajectory expanding methods exhibit similarly low DTL scores. However, our method shows an improvement of about 50% in DTL compared to the two baselines when the movement loss is not added. Through further augmentation by the movement loss, our method demonstrates a significant 100% enhancement in DTL.\nAlthough there is a slight decrease in FID performance after adding the movement loss, we believe that this minor difference can be negligible due to the complexity of the COCO image distribution.\nThe qualitative analysis of the components in our proposed method is shown in Figure 7  ###reference_###. We can observe that both of the trajectory expanding based method and the prior structure based guidance method fail to generate outputs that strictly adhere to the trajectory control, potentially resulting in similar issues encountered with the box-based and mask-based approaches. Additionally, mask-based methods may struggle to capture effective prior structures of the objects. In contrast, our approach, without introducing additional movement loss, is capable of generating objects that adhere to the trajectory (top). However, due to the lack of suppression of irrelevant positions in the attention far away from the given trajectory, extra object generations occur (bottom). This issue is alleviated by further adding the movement loss.\nThe effect of the hyperparameter  is shown in Table 4  ###reference_### and Figure 12  ###reference_### of Appendix. It shows that when , it yields the highest DTL results. However, we also notice a comparable performance when , and increasing  further leads to a significant decrease in FID. In addition, as shown in Figure 12  ###reference_### of Appendix, we observe that excessively large values lead to over-suppression of the entire image, while values in the range of [5,10] yield the best results. Therefore, the default  is set to 10."

To address this, we compare our method with previous training-free methods by providing user studies on the results\u2019 quality, controllability, and user-friendliness, based on the average scores from 15 users, as shown in Table 2  ###reference_###.\nThe visual examples of the comparisons are shown in Figure 11  ###reference_### of Appendix. Mask-based methods often introduce excessive manual priors by utilizing too detailed masks, leading to the overly controlled generation of distorted and unrealistic objects. For example, this can be observed in the generation of the distorted airplanes (c) and elephants (d). Conversely, box-based methods, with their too coarse control conditions, completely disregard prior information about the object, leading to the generation of deformed and unnatural images, such as the floating frisbee (a), oversized umbrella (b), and snowboard depicted at a unreasonable angle (e). In contrast, our trajectory-based approach does not excessively intervene in the prior structure of the object and, with user-friendly simple controls, is capable of generating natural images.\nIn addition, it is noteworthy that trained layout text-to-image generation methods often have limitations in accommodating diverse semantic categories and conditional domains. This often necessitates retraining to adapt to new conditions, incurring additional cost and time.\nHowever, our innovative training-free method can seamlessly adapts the model to any semantic input,\noffering unparalleled convenience and flexibility to users."

+    "abstract": "Inspired by the tremendous success of Large Language Models (LLMs), existing X-ray medical report generation methods attempt to leverage large models to achieve better performance. They usually adopt a Transformer to extract the visual features of a given X-ray image, and then, feed them into the LLM for text generation. How to extract more effective information for the LLMs to help them improve final results is an urgent problem that needs to be solved. Additionally, the use of visual Transformer models also brings high computational complexity. To address these issues, this paper proposes a novel context-guided efficient X-ray medical report generation framework. Specifically, we introduce the Mamba as the vision backbone with linear complexity, and the performance obtained is comparable to that of the strong Transformer model. More importantly, we perform context retrieval from the training set for samples within each mini-batch during the training phase, utilizing both positively and negatively related samples to enhance feature representation and discriminative learning. Subsequently, we feed the vision tokens, context information, and prompt statements to invoke the LLM for generating high-quality medical reports. Extensive experiments on three X-ray report generation datasets (i.e., IU-Xray, MIMIC-CXR, CheXpert Plus) fully validated the effectiveness of our proposed model.\nThe source code of this work will be released on https://github.com/Event-AHU/Medical_Image_Analysis.",

+            "text": "X-ray image based medical report generation is one of the typical applications of Artificial Intelligence (AI) in healthcare. It aims to utilize powerful AI models to directly generate high-quality medical reports from given X-ray images, thereby alleviating the workload of doctors and reducing patient waiting times. Although the performance of this task has made significant strides with the development of AI, it still falls short of matching the expertise of professional physicians due to various challenges. Due to privacy concerns surrounding X-ray data, there is a lack of quality and diversity in the training datasets, and the rarity of certain diseases and abnormal conditions also results in poor generalization performance of the models. Therefore, the research on X-ray image based report generation is still a very important but unsolved problem.\n###figure_1### Due to the good generalization of deep learning, the performance of X-ray medical report generation has seen steady improvements. For example, Cao et al. propose the Multi-modal Memory Transformer Network (MMTN) [5  ###reference_b5###] for image-report consistent medical report generation. Jin et al. introduce the PromptMRG [19  ###reference_b19###] which attempts to enhance the diagnostic accuracy in the report by feeding diagnosis-aware prompts. Li et al. proposed a new radiological reports DCL [24  ###reference_b24###] framework that uses dynamic graphs to integrate specific and general knowledge to improve visual representation. This framework also enhances visual and textual representation by leveraging contrastive learning objectives. KiUT [18  ###reference_b18###] utilizes the U connection between the encoder and decoder to effectively integrate different levels of visual information. It introduces a knowledge graph and uses a distillation technique to produce reports that are more aligned with real-world conditions. METransformer [46  ###reference_b46###] simulates multi-expert joint diagnostics by introducing multiple learnable \u201cexpert\u201d tokens. These tokens focus on different areas while interacting with each other to capture reliable and complementary visual information, facilitating the parallel generation of diagnostic reports.\nAlthough these models have achieved good results, their overall performance is still far from reaching the level of human experts. How to narrow the gap further with professional doctors remains a question worth pondering and researching.\nInspired by the great success of LLMs in natural language processing (NLP), some researchers also introduced LLMs for medical report generation. Specifically, Liu et al. [26  ###reference_b26###] propose to augment the LLMs-based radiology report generation using in-domain instance induction and coarse-to-fine decoding.\nAlthough better performance can be obtained, these models still achieve their efficiency and performance bottlenecks due to the following issues:\nFirstly, the performance of current LLMs heavily relies on the tokens humans feed into, for example, the prompt sentence, visual tokens, etc. More comprehensive inputs can guide the LLMs to generate high-quality medical reports. However, seldom of current works consider the context samples (e.g., the samples with/without disease) which may be very important cues for the text generation of the current sample.\nSecondly, they adopt the Transformer network as the vision backbone which is computationally expensive (). When handling long-range visual tokens (e.g., the raw X-ray images are usually high-definition), the self-attention in the Transformer often performs poorly on the speed, memory usage, etc.\nWith these issues in mind, in this work, we propose a novel X-ray medical report generation framework that adopts the Mamba [14  ###reference_b14###] as the backbone and mines the context samples to guide the large language models for high-quality report generation. A comparison between existing models and ours is illustrated in Fig. 1  ###reference_### (a-d).\nWe partition the input X-ray image into patches and project them into visual tokens. Then, the Mamba backbone network is adopted for efficient and effective visual token processing. More importantly, we retrieve some context samples from the training subset for each image in the mini-batch to help our report generator understand which samples are likely to have diseases and which do not. These context samples are also processed using the Mamba backbone and subtracting the global tokens of the current image to get the residual tokens. We provide the context prompts to assist the LLM in distinguishing whether certain tokens are related to diseases. As shown in Fig. 1  ###reference_### (e), it is easy to find that these retrieved positive and negative samples are easily distinguishable from the perspective of the t-SNE [40  ###reference_b40###] feature distribution. Finally, we feed these visual tokens, context tokens, and prompts into the LLM for high-quality X-ray medical report generation. Extensive experiments on two widely used benchmark datasets fully validated the effectiveness of our proposed framework.\nTo sum up, the main contributions of this work can be listed as follows:\n1). We propose a novel large language model based X-ray medical report generation framework that is augmented by context samples in the training phase, termed R2GenCSR.\n2). We propose an efficient and effective half-precision vision Mamba that achieves comparable performance to the widely used Transformer backbone network for the X-ray medical report generation task.\n3). Extensive experiments on the widely used IU-Xray, MIMIC-CXR, and CheXpert Plus datasets fully validated the effectiveness of our proposed X-ray report generation framework."

The context learning methods [42  ###reference_b42###, 12  ###reference_b12###] suggest that other samples in the training set may still play a positive role in each round of model optimization. Therefore, we consider designing a method to mine samples that are positively and negatively correlated with the current sample to enhance discriminative feature learning, thereby better guiding the LLM to generate accurate medical reports.\nPositive and Negative Sample Selection. \nFor each sample in a mini-batch, we can retrieve its context samples based on keywords in the medical reports. In our implementation, we exploit two different approaches:\n1). We adopt the CheXbert [34  ###reference_b34###] to find the possible 14 kinds of diseases from the annotated medical report. If the sample is annotated as No Finding, we treat it as a negative context sample (without disease), otherwise positive (with disease).\n2). We find that the medical report with and without Note symbol can be roughly divided based on visual features, as illustrated in Fig. 1  ###reference_### (e). Similarly, we can treat the context samples with/without Note as the positive/negative samples, respectively.\nIn addition, we also randomly select context samples to augment the training of our proposed R2GenCSR model.\nAfter the context samples are retrieved, we extract the global visual features of X-ray images as  using the Mamba backbone. These features are then projected into the language space of the LLM using a learnable projection layer, resulting in . This projection aligns the visual features with the text embeddings used by the LLM, facilitating seamless integration of visual and textual information.\nResidual Calculation. \nTo guide the large language model to generate more accurate medical reports, in this paper, we measure the difference between the current input X-ray sample and context samples, and term the difference as residual tokens. For each context sample, we assign a disease prompt \u201cWith disease\u201d or \u201cNormal\u201d and also take the visual-prompt difference into consideration, i.e.,\nwhere  and  denote the projected and tokenized features of the -th positive and negative image, respectively.

Each token, including those in the residuals and the original text, is converted into an embedding vector by the previous step, which ensures all elements of the prompt are represented in a manner that the LLM can effectively understand and process. Therefore, the final prompt for the LLM is constructed by concatenating the residuals and tokenized features as follows:\nHere,  and  are the tokenized text and vision token representations of the current image, respectively.

During this process, the LLM is fine-tuned specifically on the tokens of the medical report, guided by the instruction prompt that encapsulates the visual and textual residuals.

As the number of context samples increases (from 3 to 10), there is a noticeable decline in performance across all metrics. We suggest that while additional context samples can contribute to a richer feature representation, an excessive number may introduce noise, detracting from the model\u2019s ability to generate accurate and coherent reports. The use of a single context sample pair also yields competitive results, but the slight improvement seen with three pairs indicates that a moderate amount of context can enhance the learning process.\nAnalysis of VMamba and Swin-Transformer for report generation. \nIn Table 10  ###reference_###, we compare the training and testing efficiency of VMamba and Swin Transformer as vision backbones on a single A800 80G GPU. Although R2GenCSR-VMamba has slightly more trainable parameters (91.7 M vs. 90.9 M) and consumes more memory (75723 MB vs. 70203 MB), its training time requires only 3.98 hours per epoch, which is less than the 5.85 hours per epoch needed for R2GenCSR-Swin. Despite similar testing times for both models, VMamba has a lower FLOPs count (1852.35 G) than Swin Transformer (1855.02 G) and the overall efficiency of R2GenCSR-VMamba is superior.\n###figure_3### Analysis of Positive-Negative context-instructed text and Instruction prompt. \nAs shown in Table 8  ###reference_###, we examine the influence of positive-negative context-instructed text and different instruction prompts on our model\u2019s report generation quality. For instance, by modifying the context-instructed text from Note: <Img></Img> normal. Note: <Img></Img> with disease. to Observation: <Img></Img> appears to be normal and healthy. Observation: <Img></Img> shows clear signs of disease., the Bleu-4 score decreased by 0.010. Similarly, by changing the instruction prompt from Generate a comprehensive and detailed diagnosis report for this chest xray image. to Construct a full and methodical diagnostic summary for the chest X-ray displayed., the Bleu-4 score decreased by 0.007. Although the differences in performance between the prompts are relatively small, optimizing prompts can subtly affect the model\u2019s output."

We introduced the Mamba model as a linear complexity vision backbone to effectively extract visual features from X-ray images, ensuring that the computational burden is significantly reduced while maintaining performance parity with the robust Transformer architecture. Our approach was complemented by the integration of vision tokens, context information, and prompt statements to facilitate the generation of high-quality medical reports by the LLM. The proposed framework, extensively evaluated on the IU-Xray, MIMIC-CXR, and CheXpert Plus datasets, has demonstrated its efficacy and state-of-the-art performance. Our work not only contributes to the advancement of automated medical report generation but also provides valuable insights for leveraging LLMs in other domains."

However, interpreting mpMRI is challenging and requires expertise from radiologists. This highlights\nthe urgent need for automated grading in mpMRI. Existing studies lack integration of clinical prior information and suffer from uneven training sample distribution due to prevalence. Therefore, we propose a solution that incorporates prior knowledge, addresses the issue of uneven medical sample distribution, and maintains high interpretability in mpMRI.\nFirstly, we introduce Prior Knowledge-Based Feature Extraction, which mathematically models the PI-RADS criteria for prostate cancer as diagnostic information into model training.\nSecondly, we propose Adaptive Recall Feedback Loss to address the extremely imbalanced data problem. This method adjusts the training dynamically based on accuracy and recall in the validation set, resulting in high accuracy and recall simultaneously in the testing set.\nThirdly, we design an Enhanced Cascade Prostate Cancer Classifier that classifies prostate cancer into different\nlevels in an interpretable way, which refines the classification results and helps with clinical intervention. Our method\nis validated through experiments on the PI-CAI dataset and outperforms other methods with a more balanced result\nin both accuracy and recall rate.",

It has the highest incidence rate among male tumors in over half of the countries [1  ###reference_b1###]. Early diagnosis is a prerequisite for subsequent clinical treatment. Therefore, it is crucial to accurately detect clinically significant prostate cancer (csPCa) to avoid overtreatment and reduce mortality. Prostate biopsy is the gold standard for diagnosing csPCa. Currently, biopsies are mostly guided by transrectal ultrasonography (TRUS). However, the difficulty in accurately identifying suspicious nodules using ultrasound poses a challenge, requiring significant expertise. Additionally, biopsy is an invasive procedure that carries risks such as bleeding, infection, and urinary retention. Therefore, a non-invasive and accurate method for diagnosing csPCa is still needed.\nMultiparametric magnetic resonance imaging (mpMRI) has become increasingly popular for diagnosing prostate cancer as it provides both anatomical and functional information. It aids in distinguishing csPCa requiring intervention, minimizing overdiagnosis and overtreatment [2  ###reference_b2###]. However, mpMRI interpretation requires substantial expertise and efforts from radiologists, prompting the urgent need for automatic diagnosis of csPCa to ease interpretation burdens and mitigate treatment risks.\nWith the development of artificial intelligence, deep learning is increasingly being applied to medical imaging and has become one of the most important methods in current medical image analysis [3  ###reference_b3###]. Many researchers have proposed efficient and mature network architectures such as ResNet [4  ###reference_b4###], for tasks such as medical image classification and segmentation. Deep learning automates task-specific information learning, eliminating the need for manual extraction efforts. Although it may sacrifice some medical interpretability, it streamlines processes and yields superior performance in targeted tasks."

+            "text": "Recently, there has been a rise in computer-aided diagnosis (CAD) solutions for prostate cancer (PCa) using mpMRI images [5  ###reference_b5###, 6  ###reference_b6###, 7  ###reference_b7###, 8  ###reference_b8###]. Conventional machine learning methods primarily use image-based approaches or radiomics for binary classification tasks [9  ###reference_b9###, 10  ###reference_b10###]. Although these methods yield satisfactory results, they often struggle with more complex multi-classification problems. Deep learning techniques have been extensively explored to address this issue [11  ###reference_b11###, 12  ###reference_b12###, 13  ###reference_b13###, 14  ###reference_b14###], particularly in the context of multi-classification tasks [15  ###reference_b15###]. however, due to the inherent complexity of the multi-classification problem, the performance is not as satisfactory as in binary classification [16  ###reference_b16###, 17  ###reference_b17###].\nExperience and evidence-based medicine are crucial for medical diagnosis. Exploring the integration of them in analyzing images for downstream tasks remains an ongoing endeavor. Matin Hosseinzadeh incorporate the anatomical segmentation mask as prior knowledge to guide the network\u2019s focus on the prostate region and improves classification performance [18  ###reference_b18###]. Alberto Rossi proposed a new deep learning architecture that enables the comparison of new cases with existing cases of prior diagnosis and increase its accuracy [19  ###reference_b19###]. Abhejit Rajagopal improved the classification performance by incorporating prior knowledge of histopathology [20  ###reference_b20###]. Their work utilizes prior information to improve performance, but the information they use is simplistic and superficial. Complicated information such as diagnostic criteria and medical judgment is not fully utilized.\nThe imbalanced sample sizes across diseases and stages may bias the classification towards specific samples.Given the cost of misdiagnosis, prioritizing recall rates for these specific samples is crucial. The loss function is a crucial component in deep learning, and an effective loss function enables the model to identify both positive and negative instances. The conventional cross-entropy loss function faces challenges in multi-classification due to strict data conditions. Tsung-Yi Lin improves it for multi-classification by introducing adjustment factors to handle unequal sample class proportions [21  ###reference_b21###]. Junjiao Tian introduced Recall Loss, a modification of conventional cross-entropy loss, which incorporates recall as a dynamic parameter. The loss is dynamically weighted based on its changing recall rate every epoch [22  ###reference_b22###]. Although these methods have achieved good results, they may not fully suit prostate cancer ISUP classification, especially in distinguishing fewer samples. This potentially leading to locally optimal solutions where samples are classified into a single class, hindering achievement of high recall rates and accuracy simultaneously.\nDiagnosis is a complex process that requires a comprehensive understanding of the disease and the patient\u2019s condition. It is often divided into multiple stages, each refining the diagnosis.The detection of csPCa is the classification of ISUP 0-1 and ISUP 2-5, which is considered the simplest task in prostate cancer classification. The classification of ISUP 2-3 versus ISUP 4-5 and ISUP 4 versus ISUP 5 is more complex, which indicate the severity of prostate and different clinical interventions. Currently, there is limited research on these complex tasks. The cascade strategy has been used in prostate cancer imaging to simplify complex problems and improve performance. G.J.S. Litjens trained a linear discriminant classifier that sequentially eliminates benign samples using binary classification cascades, ultimately identifying prostate cancer samples [23  ###reference_b23###]. Lina Zhu achieved good performance in fully automated detection and segmentation of csPCa using a Res-UNet cascade deep learning model trained on ADC and T2WI [24  ###reference_b24###]. Most of the aforementioned cascade works primarily refine classification categories through cascading. However, we believe that the cascade strategy also serves to refine metrics."

Our specific contributions are as follows:\nWe propose a novel loss function, Recall Feedback Adaptive Loss (RFAloss), which dynamically adjusts during training to expand the parameter search space and adjust the search direction based on the feedback of recall. This addresses the bias caused by the imbalanced sample distribution. We introduce two dynamic parameters and three hyperparameters, evaluate their roles along with the loss function, and prove that RFAloss achieves high recall rates and maintains relatively high accuracy under suitable hyperparameters.\nWe introduce a prior knowledge-based feature extraction strategy (F-E) based on the report standards of prostate cancer in mpMRI. We validate the effectiveness of this strategy from both visualization and experimental perspectives. When using the F-E results as additional input, it significantly improves the model\u2019s ability to generalize on the test set.\nWe propose a cascade confidence refinement strategy to improve the diagnostic process for physicians. This strategy allows the classifier to output and fuse results based on clinical practice, resulting in a more balanced confusion matrix even with highly imbalanced samples."

Typical prostate cancer shows a hypointense signal in T2WI and ADC images and a hyperintense signal in DWI. The risk of prostate cancer is evaluated by the intensity and the area of the abnormal signal zone. By incorporating this prior knowledge into our model, we improve the generalization ability of the model. This also improve the interpretability of the model, which can help doctors in diagnosis by highlighting areas with a high probability of lesions.\nQuantifying these standards was difficult because signal contrast and local signal range are subjective. To overcome this challenge, we enhanced subjective features by emphasizing important information across different sequences and reducing interference from blurred signals. We quantified local signals by assessing differences in symmetrical positions, where significant intensity discrepancies indicate a high probability of abnormal tissue.Besides, considering that lesions may occur along the gland\u2019s axis, we compared the differences between the axial position and surrounding positions. As a result, we refined our theoretical framework and developed the following specific modeling algorithm:"

Although this loss achieved parameter adjustments along with changes in recall, the change is linear and exhibited low dynamic variability. Furthermore, it lacks sufficient differentiation of disease samples and is susceptible to local optima because it only adjusts one parameter dynamically.\nTherefore, we aim to guide the loss function to search towards the recall of the class of interest. We introduce dynamic differential feedback coefficients  and . The coefficient  directs the loss function to focus on the cases of interest, while  guides it to focus on the cases that are not of interest. The feedback coefficient  is defined as:\nwhere  represents accuracy,  represents recall. When the recall in validation is low, both recall and accuracy are fed back into the training process. This encourages the model to change its search direction, expand its scope, and find the parameter that minimizes loss by maximizing recall and accuracy. Combining Equation 13  ###reference_###, our loss function should be a piecewise function conditioned on the predicted class of the output as follows:\nWhen the feedback is triggered, the search scope expanded so that the model can escape the local optima. Therefore, instead of using smoothing methods like exponential moving averages, we incorporate average accuracy and recall results per five epochs as feedback parameters in the loss function for adaptive feedback. The effect of RFAloss derives from the difference between  and . As  changes dynamically during training, so does the difference between  and . After an iteration with a noticeable difference between recall and accuracy, the baseline of the loss function shifts, leading to a significant change in the gradient descent direction. For example, if the recall changes from 1 to 0.5 after an iteration, the attention of the loss function to  increases from one order of magnitude to two orders of magnitude. Consequently, the model prefers to classify  correctly and deviate from its original search direction, leading to both a change in search direction and an expansion of the search scope."

Classifier1 distinguishes between levels 0-1 and 2-5,and is utilized for diagnosing csPCa, with ISUP levels 0-1 indicating a benign lesion or non-csPCa. while classifier2 separates levels 2-3 from levels 4-5, determines the appropriate clinical interventions for prostate patients, where ISUP levels 2-3 suggest middle-grade csPCa with a relatively positive prognosis and ISUP levels 4-5 indicate high-grade csPCa with an invasion tendency. classifier 3 focuses on classifying level 4 versus level 5, quantifiing the severity of high-grade csPCa, where surgery may be effective for ISUP level 4 patients but not for ISUP level 5 due to increased invasiveness and malignancy.\nTo refine the confidence of the final classification, we cascaded the results of the three classifiers.

However, the experiments in Table 1  ###reference_### show that increased fluctuation indicates stronger feedback and a wider search range but does not necessarily lead to improved final metric results.\nWe introduce  to improve accuracy by directing feedback towards accuracy improvement. In our study, the positive class is significantly underrepresented. Additionally, our loss function is designed to prioritize a high recall rate by predicting more positive examples. Therefore, we attribute the lower accuracy to the scarcity of predictions for negative samples. To improve the accuracy, we need to increase the attention to negative examples.

This indicates that there is a higher attention to negative examples compared to positive examples, which supports our hypothesis. However, if  is too small,  tends to approach 1.

When recall is low, the loss function amplifies attention to positives, penalizing false negatives more significantly, prompting a shift in the loss function\u2019s benchmark and search direction. It ensures the discovery of more samples with outstanding recall. Therefore, the amplitude of curve fluctuations should not be too large to maintain correct search direction.

+            "text": "Understanding the evolution of the interface between two phases undergoing a phase transition is an important problem in both physics and mathematics [1  ###reference_b1###].\nOne classical approach to studying this behavior is through Stefan problems [45  ###reference_b45###, 47  ###reference_b47###, 49  ###reference_b49###].\nGenerally speaking, the formulation of a Stefan problem involves solving a heat equation within each respective phase, while adhering to prescribed initial and boundary conditions. At the interface, where the two phases meet, the temperature is fixed at the critical temperature for phase transition - a key feature in classical Stefan problems. To complete the mathematical framework, an additional equation known as the Stefan condition is imposed. This condition, rooted in energy conservation principles, serves to precisely determine the position of the advancing interface.\nStefan problems have been one of the most well-studied classes of free boundary problems dating back over a hundred years with the pioneering work by Lame [32  ###reference_b32###] and Stefan [47  ###reference_b47###] and more recent results by [45  ###reference_b45###, 44  ###reference_b44###, 5  ###reference_b5###, 38  ###reference_b38###, 42  ###reference_b42###].\nKey results such as the existence of solutions , the continuity of the moving boundary and the regularity of solutions can be found in a series of papers [8  ###reference_b8###, 31  ###reference_b31###, 10  ###reference_b10###, 9  ###reference_b9###, 3  ###reference_b3###, 25  ###reference_b25###].\nHowever, it remains unclear whether such a simple model is truly valid in reality. For instance, classical Stefan problems typically consider only a single interface by fixing the temperature at the phase change temperature at the liquid-solid interface, which is not true in general.\nWhereas in reality, it is often observed that the liquid phase is below its freezing point or the solid phase is above it, which is known as supercooling and superheating [11  ###reference_b11###, 46  ###reference_b46###, 24  ###reference_b24###, 4  ###reference_b4###, 21  ###reference_b21###].\nMore importantly, one could ask what is the thermodynamic reasoning behind Stefan problems? Are these model thermodynamically consistent, i.e., do they satisfy the first and second laws of thermodynamics?\nIn this paper, we revisit this classical problem by developing a new thermodynamically consistent non-isothermal diffuse interface model for phase transition and interface evolution involving heat transfer.\nIn contrast to the approaches in Stefan problems, which assume that there exists\na sharp interface between the liquid and solid phase, diffuse interface models [2  ###reference_b2###] assume that there exists an interfacial region between the two phases, which is closer to the physical reality [11  ###reference_b11###]. One can introduce a smooth space-time-dependent phase function  to identify each phase, as well as the interface.\nClassical diffuse interface models often consider isothermal cases [2  ###reference_b2###, 15  ###reference_b15###].\nHowever, to model phase transitions and heat transfer as considered in the Stefan problem [33  ###reference_b33###], it is crucial to include the temperature as an additional variable, which is challenging because one requires the system to be both physically and mathematically consistent.\nSome advances in this direction have been made by Caginalp in a series of papers [11  ###reference_b11###, 12  ###reference_b12###, 14  ###reference_b14###, 13  ###reference_b13###], who was one of the first to study temperature dependent phase field models and who found the relation of these systems with free boundary problems, in particular the Stefan problem, as their sharp interface limit [13  ###reference_b13###]. Around the same time, Penrose and Fife introduced their famous model, where both the phase parameter and the temperature can depend on space and time [43  ###reference_b43###]. The connection between the Penrose-Fife model and Stefan-type problems has been explored in the literature [20  ###reference_b20###, 19  ###reference_b19###].\nHowever, in both models, the temperature equation only contains linear terms in both the phase variable and temperature variable.\nIn this work we take a new approach by combining ideas from the energetic variational approach with non-equilibrium thermodynamics. This approach works with the entropy of the system rather than the enthalpy as main thermodynamic quantity as most of the previous work, which allows us to include higher order nonlinearities of the system that could get lost in other cases.\nFurthermore, our approach allows for various assumptions regarding the kinematics of the temperature, corresponding to different heat transfer mechanisms in physical bodies. This flexibility enables applications across a wide range of physical models.\nBy assuming the temperature is on a fixed background and not transported with material particles,\nwe derive a model that generalizes the classical Allen-Cahn equation to a non-isothermal setting. We then investigate the sharp interface limit of this non-isothermal Allen-Cahn equation, which validates the classical Stefan problem within a specific physical regime.\nThrough asymptotic analysis, we show that under certain scaling of the melting/freezing energy, the motion of the liquid-solid interface and the temperature interface coincide and are governed by its mean curvature. We also conduct numerical simulations of the diffuse interface model, which demonstrate that the motion of both interfaces follows the mean curvature flow, at least for a short time. The simulation results further support the asymptotic analysis and indicate that the Stefan model is a good reduced model within this regime.\nThe rest of paper is organized as follows: In Section 2  ###reference_###, we derive, following a free energy approach, non-isothermal diffuse interface models, including the non-isothermal Allen-Cahn equation, under various assumptions on the kinematics of the temperature.\nIn Section 3  ###reference_###, we show that the formal asymptotic limit of the non-isothermal Allen-Cahn system, under certain scaling of the melting/freezing energy, leads to a two-phase Stefan-like problem with curvature effects.\nHence, the Stefan problem can be seen as a reduced model of the non-isothermal Allen-Cahn equation. Finally, we perform some numerical studies to the non-isothermal Allen-Cahn model\nin Section 4  ###reference_###."

+    "abstract": "Recent studies highlight the effectiveness of using in-context learning (ICL) to steer large language models (LLMs) in processing tabular data, a challenging task given the structured nature of such data. Despite advancements in performance, the fairness implications of these methods are less understood. This study investigates how varying demonstrations within ICL prompts influence the fairness outcomes of LLMs. Our findings reveal that deliberately including minority group samples in prompts significantly boosts fairness without sacrificing predictive accuracy. Further experiments demonstrate that the proportion of minority to majority samples in demonstrations affects the trade-off between fairness and prediction accuracy. Based on these insights, we introduce a mitigation technique that employs clustering and evolutionary strategies to curate a diverse and representative sample set from the training data. This approach aims to enhance both predictive performance and fairness in ICL applications. Experimental results validate that our proposed method dramatically improves fairness across various metrics, showing its efficacy in real-world scenarios.",

+            "text": "Large Language Models (LLMs), such as GPT-4 (OpenAI, 2023  ###reference_b27###), Claude-3 (AnthropicAI, 2023  ###reference_b3###), and LLaMA-2 (Touvron et al., 2023  ###reference_b33###), have achieved state-of-the-art performance in many natural language processing tasks.\nThese LLMs can adapt to different tasks by adding in-context prompts, without needing to retrain on the entire new dataset.\nThis optimization technique for LLMs is called in-context learning (ICL), which leverages specific input prompts to guide LLMs to generate more accurate outputs.\nRecent research suggests that incorporating specially selected demonstrations into these prompts can significantly enhance LLM performance (Brown et al., 2020  ###reference_b6###; Schick and Sch\u00fctze, 2020  ###reference_b29###).\nDue to prompt length limitations, traditional LLMs have faced challenges in processing demonstrations from tabular datasets, which have a large number of features. However, with recent LLMs relaxing input length constraints, new avenues for applications in tabular datasets are opening up. (Hegselmann et al., 2023  ###reference_b14###) has confirmed the predictive capabilities of LLMs on datasets from UCI repository.\nConsidering the usages of tabular data in high-stakes domains (Grinsztajn et al., 2022  ###reference_b12###), ensuring fairness alongside prediction performance is crucial for increasing trust in LLMs.\n(Liu et al., 2023  ###reference_b21###) has highlighted biases in LLM predictions with tabular datasets, but there are limited further investigations on how the fairness of LLMs performance varies with different ICL demonstrations.\nTo bridge this gap, we aim to answer the following research question: How do different demonstration strategies impact the fairness performance of LLMs on tabular classification tasks? And is there a demonstration strategy better than other strategies?\nTo better understand the impact of in-context learning on fairness, our proposed demonstration strategy considers the distribution of both demographic groups and target labels. A dataset can be divided into subgroups by demographic features, labelling the smallest as the minority (underrepresented) and the larger one as the majority. The fairness investigation compares differences between majority and minority groups. Our investigation includes evaluating five advanced LLMs, i.e., Text-davinci-003, GPT-3.5-turbo, GPT-4-turbo 111https://platform.openai.com/docs/models/  ###reference_###, Claude-3 Haiku, and Claude-3 Sonnet222https://www.anthropic.com/news/claude-3-family  ###reference_mily###, across two fairness-focused tabular datasets: Credit and Adult. We found that prioritizing underrepresented samples and conscientiously including minority demographic groups and target labels during few-shot learning can significantly improve the fairness performance in LLMs output.\nDespite the experimental observations, we are still wondering: Why does prioritizing minority group demonstrations benefit the fairness performance of LLMs in tabular-based classification tasks? To further clarify this phenomenon, we perturb prediction labels and sensitive features in selected demonstrations and compare how the prediction outcomes of LLMs would be altered. Through these perturbation experiments, we found that increasing the proportion of underrepresented labels enhances fairness, but can lead to a decline in prediction performance, and vice versa.\nUp until now, the above findings and explanations have been based on random demonstration selection. We hypothesize that: We can deliberately select demonstrations to further improve fairness performance.\nMotivated by the fiLter-thEn-Search (LENS) (Li and Qiu, 2023  ###reference_b18###) for textual classification, we adopt a similar process for extracting tabular demonstrations: first refine the training data set into a candidate pool and then sample and evaluate these candidates to identify the most supportive demonstrations. To this end, we introduced the\nFairness via Clustering-Genetic (FCG) algorithm to effectively extract representative samples, to further enhance the fairness of LLM. Unlike LENS, which relies on progressive iterations on LLMs for candidate selection, our FCG method utilizes clustering. Clustering does not require access to LLMs and maintains diversity among the selected shots, effectively addressing concerns related to the time required for iterations and the cost of LLM access.\nAdditionally, previous studies often assume the same selection probabilities for candidates across evaluation iterations, requiring enormous iterations to ensure that each sample is equally considered. Inspired by genetic evolution concepts, we adopt dynamic probabilities which give priority to representative samples with higher selection chances. Sample representativeness is measured by the LLM performance score, whose score is updated for each iteration. In this way, FCG can narrow the final sample set more efficiently, and drastically reduce the number of iterations needed.\nWe implement experiments to evaluate the proposed FCG demonstration selection method.\nThe results confirm that FCG algorithm improves LLMs performance in almost all strategies, with prioritizing the minority group still yielding the best results.\nTo conclude, the main contributions in this paper are as follows:\nWe find that prioritizing underrepresented samples and conscientiously including minority demographic groups and target labels during few-shot learning can dramatically improve the fairness performance in LLM output (Section 3  ###reference_###).\nWe explain why prioritizing minorities leads to a fairer solution, and find the trade-off between LLMs\u2019 performance and demographic labels: increasing the ratio of underrepresented labels enhances fairness, but can lead to a decline in prediction performance, and vice versa (Section 4  ###reference_###).\nWe propose the FCG (Fairness via Clustering-Genetic) algorithm, an efficient approach to retrieve a diverse and representative set of demonstrations from training data. Across almost all strategies, FCG enhances fairness in LLMs under in-context learning (Section 5  ###reference_###)."

We select two tabular-based fairness datasets: default of credit card clients dataset (Credit, (Yeh, 2016  ###reference_b38###)) and adult income (Adult, (Becker and Kohavi, 1996  ###reference_b5###)). The Credit dataset covers information on credit card clients in Taiwan, including demographics, bills, payment history, etc. Its target is to predict whether there will be an overdue payment next month.

Part \u2776 clarifies the task and defines the format of output prediction label options. Part \u2777 contains a series of demonstrations as references. Part \u2778 is the sample to be predicted.\nWe consider both zero-shot learning and few-shot learning in our experiments. Zero-shot learning refers to LLMs with a prompt exclude demonstration references (without \u2777) and is set as the baseline.

Similar patterns are observed in , where fairness gradually increases by 8.1% when modifying from male to female.\nIn most cases, the perturbation results align with the intuition that distorting real data can degrade its quality, thus potentially leading to negative impacts on LLMs performance.

We also consider absolute values of FPR and TPR within each subgroup to fully assess fairness changes in perturbations.\nIn income perturbations, replacing the income labels results in a decrease in TPR and FPR for both female and male groups, with a more significant decline observed in the female group. This reduction is most notable when income labels are changed to high-income. In a few cases, the relative metrics  and  show improvement compared to the results without perturbations. However, the corresponding absolute metrics TPR and FPR do not show consistent trends and worsen instead. This inconsistency makes it difficult to validate the impact of income on fairness performance.

For absolute values, flipping female labels to male in  leads to a 4.69% increase in FPR and a 5.47% increase in TPR for the male group. Similarly, transforming male labels to female in  results in increases in both TPR and FPR for the female group. Similar trends are found in their relative values.

LLMs exhibit improved performance when the proportion of minority groups increases: they become fairer compared to the used of original data when perturbing demographic labels male to female. Therefore, we conclude that prioritizing demonstrations from minority groups can maximize these advantages and promote fairness in LLMs. In contrast, perturbing labels leads to demonstrations becoming less reliable, as they can lead models to learn noise and perform worse.

In the ablation study, part of the samples are selected using the same flow of choosing the top K samples based on their EvolScores, while the other part is selected randomly.

Through experiments, we found that prioritizing underrepresented groups and including minority examples in the few-shot demonstrations can significantly enhance fairness performance, without sacrificing predictive accuracy. Further analysis revealed that increasing the proportion of underrepresented labels improves fairness metrics like demographic parity and equal odds. To efficiently retrieve effective demonstrations, we proposed the FCG algorithm that uses clustering and genetic evolution to select a diverse and representative set of examples from the training data. Across multiple strategies and datasets, experimental results indicate that FCG was able to improve fairness compared to random sampling."

Additionally, our focus on binary classification with a single sensitive feature limits the broader applicability of our findings. In future, we plan to explore LLM\u2019s intersectional fairness and its performance in multi-classification tasks.

(2023  ###reference_b19###) tested bias and stereotypes on LLMs using the BBQ dataset for question answering, finding that most models exhibit biases distinct from broader societal trends. Wang et al. (2023  ###reference_b34###) assesses bias by prompting GPT models to express their views on stereotypes.\nMost bias studies have focused on representational harms caused by LLM generations, with only limited studies Hegselmann et al. (2023  ###reference_b14###) addressing fairness concerns classification problems with tabular datasets.\nBesides investigation on pre-trained LLMs, recent research also focuses on ensuring fairness in other trained machine learning models, such as perturbation-based Zhang et al.

(2021  ###reference_b22###); Zhao et al. (2021  ###reference_b42###); Shi et al. (2022  ###reference_b30###).

LENS Li and Qiu (2023  ###reference_b18###) proposed a two-step filter and search algorithm to identify informative support examples.

Here, we discuss these two methods and further explore the possibility of combining them. Given the time consumption of LENs, we simplified it by setting batch size to 8, and template index to {0,1}. The training dataset is randomly split () into groups of 500 samples for parallel computation, with other settings kept at their defaults. For LENs with FCG, we follow our FCG parameters setting: first extract 160 representative samples by clustering, then perform LENs to find the final candidates.\nFigure 5  ###reference_### presents the overall workflow of FCG, LENs, and their possible combination. Both FCG and LENs involve two steps: (1) selecting partial data and (2) searching for the optimal based on the filtered data. There are two key differences in implementations.\nSupervised & Unsupervised LENs algorithm uses LLMs as the classification assistance in both stages. This is a straightforward and effective way. However, since the processing time of language models is related to the amount of information in the input text, the selection time can become very long when the input data is lengthy.\nThis study focuses on tabular datasets, which have longer text when converted into prompts compared to commonly used NLP datasets. Therefore, we consider to optimize the method to reduce processing time and improve efficiency. Our FCG replaces LLMs with simpler unsupervised algorithms in the first stage.\nOn the adult dataset, LENs can take over 50 hours to find supportive demonstrations (), while FCG takes less than 3 hours (). The result in Table 17  ###reference_### validates the effectiveness: even if LLMs are not used initially, using LLMs to search on the validation set in the second stage can still find demonstrations that improve the model\u2019s prediction.\nFairness Awareness Another difference is that LENs use accuracy as the sole evaluation metric when selecting demonstrations. Our FCG takes sensitive features into account and selects demonstrations at the subgroup level. Additionally, FCG considers both accuracy and fairness metrics as constraints when calculating performance scores. Table 17  ###reference_### confirms FCG with minority demonstrations prioritised strategy () shows fairer performance than baseline.\nFurthermore, we extend LENs with FCG (as shown on the right side of Figure 5  ###reference_###) to make it fairness-aware. Table 17  ###reference_### proves the effectiveness of this combination and also shows the best performance achieved when using more minority demonstrations ().\n###figure_14###"

points).\nNote that  is used since  introduces approximation errors, see Fig. fig. 2  ###reference_###.\nFor the iterations, one evaluates the steady-state  as shown in Fig. fig. 3  ###reference_###.\nSince the iterations use different progress rate formulae, the obtained  is normalized by their respective progress rate zero (numerically obtained zero of eq. 7  ###reference_### for Iter. 1A and 1B, eq. 10  ###reference_### for Iter. 2A and 2B).\nThis distinction is important since it will largely explain the observed deviations.\nIn Fig. fig. 4  ###reference_###, Iteration 1A shows the best agreement with measured values.\nThe largest deviations occur at small  due to missing higher order -dependent terms of the progress rate eq. 7  ###reference_###.\nAt larger -values the observed deviations become very small.\nIteration 1B introduces some notable deviations, however, they are comparably small.\nBy introducing the large population approximation (Iter. 2A and 2B),\nlarger deviations can be observed, especially for small  and for , which was expected based on the applied approximations.\nThese deviations are not due to the Taylor-expansion of the -update (using the full exponential eq. 34  ###reference_### yields very similar results as Iter. 2A, not shown in plot), but can be attributed to the large population approximation.\nAs an example, the term  of eq. 46c  ###reference_.3### contains additional - and -dependent terms which are not present in eq. 47c  ###reference_.3###.\nThe same holds for progress rate  and .\nUnfortunately, closed-form solutions of the steady-state by including the higher order terms cannot be obtained.\nHowever, one can still deduce important scaling properties of the CSA w.r.t.  and  by using the large population approximation.\nFurthermore, in the context of adaptive population control on noisy or multimodal functions, the exact prediction of  has not the highest priority.\nMore important is the scaling property of  w.r.t.  and  to understand how the -adaptation changes as population or dimensionality parameters change.\nHence, the analytic derivation is continued based on the large population approximation to investigate the scaling properties of the CSA-adaptation.\n###figure_8### ###figure_9###"

+    "abstract": "In a real federated learning (FL) system, communication overhead for passing model parameters between the clients and the parameter server (PS) is often a bottleneck.\nHierarchical federated learning (HFL) that poses multiple edge servers (ESs) between clients and the PS can partially alleviate communication pressure but still needs the aggregation of model parameters from multiple ESs at the PS.\nTo further reduce communication overhead, we bring sequential FL (SFL) into HFL for the first time, which removes the central PS and enables the model training to be completed only through passing the global model between two adjacent ESs for each iteration, and propose a novel algorithm adaptive to such a combinational framework, referred to as Fed-CHS. Convergence results are derived for strongly convex and non-convex loss functions under various data heterogeneity setups, which show comparable convergence performance with the algorithms for HFL or SFL solely.\nExperimental results provide evidence of the superiority of our proposed Fed-CHS on both communication overhead saving and test accuracy over baseline methods.",

Hereafter, the PS aggregates these uploaded local model parameters to have a new one and broadcasts it to each participating client.\nConvergence of global model can be promised in such a framework and no raw data is transmitted between any participating client and the PS (Gu et al.,, 2021  ###reference_b11###; Collins et al.,, 2022  ###reference_b8###; Song et al.,, 2023  ###reference_b44###).\nIn traditional FL architecture, as the number of participating clients grows, it is very pricey to sustain a dedicated communication link between every client and the PS for global model updating, considering the data size of model parameter nowadays is generally enormous\n(WANG et al.,, 2019  ###reference_b47###; Rothchild et al.,, 2020  ###reference_b41###; Luo et al.,, 2021  ###reference_b30###; Shah and Lau,, 2023  ###reference_b42###; Amiri and G\u00fcnd\u00fcz,, 2020  ###reference_b3###).\nTo overcome this challenge, some efforts are made to reduce the number of bits to offload for each communication hop, e.g., through pruning the neural network model (Horv\u00e1th et al.,, 2021  ###reference_b12###; Zhang et al.,, 2022  ###reference_b58###) or compressing the model parameter (Bibikar et al.,, 2022  ###reference_b6###), etc.\nDifferently, some other works try to save the number of communication hops by designing new aggregation mechanisms with a concern of network topology.\nHierarchical Federated Learning (HFL) (Abad et al.,, 2020  ###reference_b1###; Briggs et al.,, 2020  ###reference_b7###; Lim et al.,, 2022  ###reference_b25###) is such a kind of example that emerges recently.\nIn HFL, massive clients are broadly distributed and have to get through the PS via an edge server (ES) in the vicinity. Dividing the set of clients into multiple clusters, within each of which there is an associated ES (Liu et al.,, 2020  ###reference_b26###; Liu et al., 2023b,  ###reference_b28###; Wang et al.,, 2023  ###reference_b51###).\nIn any round of local model aggregation, each ES first aggregates the local models from the clients in its cluster and then pushes the aggregated one to the PS to generate the global model parameter (Yang,, 2021  ###reference_b54###; Ng et al.,, 2022  ###reference_b36###; Qu et al.,, 2022  ###reference_b40###; Liu et al., 2023a,  ###reference_b27###).\nThrough this operation, the communication hops for offloading each client\u2019s specific local model parameter from the associated ES node to the central PS are waived (Deng et al.,, 2021  ###reference_b10###; Shi et al.,, 2021  ###reference_b43###).\nEven with HFL,\nthe round-by-round aggregations of combined model parameters from every ES at the PS is still a communication-heavy task (Wang et al.,, 2021  ###reference_b50###).\nThis situation is even worse when the group of ESs and the PS are in a highly dynamic network, weakly interconnected, or subject to network topology mismatch, i.e., the topology of ESs and the PS is not in a stable and star shape (Pham et al.,, 2022  ###reference_b39###; Zhou et al.,, 2023  ###reference_b61###).\nTo overcome this challenge, the idea of sequential FL (SFL) that removes PS from the FL system and allows global model parameters updated among participating clients sequentially, can serve as an enhancement, but has not been brought into HFL in literature.\nTo leverage SFL in the framework of HFL, aggregated model parameter is updated sequentially among ESs,\nwhich exempts the parallel offloading of each ES to the PS (Sun et al.,, 2022  ###reference_b45###; Ayache et al.,, 2023  ###reference_b4###).\nThe combination of HFL and SFL is adaptive to a broad range of network topologies.\nSome exemplary applications include, but are not limited to, Internet of Vehicles (IoV) and Integrated Low-earth Orbit (LEO) Satellite-Terrestrial Network, whose detailed descriptions are listed in Appendix D  ###reference_###.\nIn addition, datasets from disjoint participating clients may be non-independent and identically distributed (non-IID) (or say be subject to data heterogeneity) due to diverse geographical environments and client characteristics (Liu et al., 2023b,  ###reference_b28###; Collins et al.,, 2022  ###reference_b8###).\nNon-IID datasets bring new challenges into convergence proving for training algorithms and have been a vital issue to address in the traditional framework of FL, HFL, or SFL (Sun et al.,, 2022  ###reference_b45###; Liu et al., 2023b,  ###reference_b28###; Song et al.,, 2023  ###reference_b44###).\nIn our combinational framework of SFL and HFL, the factor of non-IID cannot be ignored either as the HFL structure enables the coverage of a broader range of clients.\n\nHow to promise convergence in such a situation is still an open problem, and cannot be answered based on existing related works that cares SFL or HFL sorely (Parsons et al.,, 2023  ###reference_b38###; Liu et al., 2023a,  ###reference_b27###).\nIn this paper, to save communication hops and overcome the data heterogeneity that are widely existed, we investigate the realization of federated learning in the combinational framework of HFL and SFL with non-IID data sets, and propose a novel aggregation algorithm named Fed-CHS.\nIn Fed-CHS, iterative training is performed cluster-by-cluster. For the currently active cluster, each client in it only needs to interact with the associated ES node, who then generates the most up-to-date global model parameter from these interactions and pushes the generated model parameter to the ES node in a neighbor cluster for next round of iteration.\nThe selection of next passing ES node is realized based on a deterministic and simple rule.\nRigorous convergence analysis is expanded when the loss function is strongly convex and non-convex, under various setup of data heterogeneity.\nContributions:\nOur main contributions are three-fold:\nAlgorithmically, we investigate the combinational framework of SFL and HFL for the first time and propose a new aggregation algorithm Fed-CHS to be adaptive to it.\nFed-CHS offers a communication overhead saving method compared with existing methods for HFL architecture or conventional FL framework and is totally different from existing communication-efficient methods that merely save the number of bits for each communication hop.\nFurthermore Fed-CHS is general to network topology, especially when the topology is highly dynamic or not in a star shape.\nTheoretically, we explore the convergence performance of Fed-CHS when the loss function is strongly convex or non-convex. Specifically, Fed-CHS can converge at a linear rate with  and a rate  for  with , which defines the rounds of training iteration among clusters and within a cluster respectively, for strongly convex loss function, and a rate of  with  and  for non-convex loss function under general data heterogeneity.\nAdditionally, when data heterogeneity fades away partly or completely, Fed-CHS can further achieve zero optimality gap for strongly convex loss function, and stationary point for non-convex loss function, respectively, while keeping the convergence rate unchanged. These convergence results are comparable with the algorithms for HFL or SFL solely.\nNumerically, we conduct extensive experiments to compare Fed-CHS with baseline methods. The results verify the advantage of our proposed Fed-CHS in test accuracy and communication overhead saving."

More details about the surveyed literature are given in Appendix E  ###reference_###.\nHierarchical Federated Learning (HFL)\nIn the framework of HFL, Tu et al., (2020  ###reference_b46###) concerns limited computation capability at clients, Hosseinalipour et al., (2022  ###reference_b13###) cares a special network connection topology like device-to-device (D2D) , and Wang et al., (2023  ###reference_b51###) takes communication bottleneck into account by allowing ES currently having bad link condition with the PS to delay the uploading of model parameter. However, Wang et al., (2023  ###reference_b51###) still requires each ES to offload aggregated model parameter to the PS. Heavy parameter offloading task is only postponed rather than diminished in Wang et al., (2023  ###reference_b51###).\nSequential Federated Learning (SFL)\nWith regard to SFL, the Next Passing Node that is going to receive the most up-to-date global model parameter, may be selected by following a fixed order or randomly.\nWhen the next passing node is chosen by following a fixed order, ring topology has to be imposed (Wang et al.,, 2022  ###reference_b49###; Zaccone et al.,, 2022  ###reference_b57###), which can hardly accommodate to various network topology in real application.\nWhen the next passing node is selected in a random way, more computation overhead may be brought in for evaluating the Lipschitz constant as required in Ayache and El Rouayheb, (2019  ###reference_b5###) or the value function for working about an multiple armed bandit (MAB) problem in Ayache et al., (2023  ###reference_b4###).\nConvergence Guarantees for Federated Learning\nIn terms of convergence analysis concerning data heterogeneity, for HFL, convex loss function is mainly concerned (Tu et al.,, 2020  ###reference_b46###; Hosseinalipour et al.,, 2022  ###reference_b13###; Wang et al.,, 2023  ###reference_b51###). Some literature, including Tu et al., (2020  ###reference_b46###); Wang et al., (2023  ###reference_b51###), cannot achieve zero optimality gap but is able to converge at linear rate, for a general convex (Tu et al.,, 2020  ###reference_b46###; Wang et al.,, 2023  ###reference_b51###) or strongly convex (Wang et al.,, 2023  ###reference_b51###) loss function.\nHosseinalipour et al., (2022  ###reference_b13###) can achieve zero optimality gap but at a convergence rate of .\nHowever, the zero optimality gap in Hosseinalipour et al., (2022  ###reference_b13###) is build on some special assumption on quantitative relationship between instant gradient of loss function and system parameter.\nWhile, for SFL, the aforementioned Mao et al., (2020  ###reference_b33###); Ayache et al., (2023  ###reference_b4###) have tried to overcome data heterogeneity.\nThe loss function is assumed to be strongly convex in Mao et al., (2020  ###reference_b33###); Ayache et al., (2023  ###reference_b4###).\nMao et al., (2020  ###reference_b33###) can achieve convergence at rate  for , while Ayache et al., (2023  ###reference_b4###) is able to further achieve zero optimality gap at at rate , which relies on the holding of a special condition between local model parameter and local gradient in the stage of initialization.\nIn summary, as the architecture evolves from conventional FL, the results of which is given in Appendix E  ###reference_###, to HFL and SFL, i.e., from simple to complex, it becomes harder and harder to get ideal results for a general convex or non-convex loss function in front of heterogeneous dataset.\nIn this situation, deriving analytical results under the combinational framework of HFL and SFL is even more challenging."

Theoretical analysis guarantees the convergence performance of the Fed-CHS for strongly convex or non-convex loss function under various setup of data heterogeneity.\nExtensive experiments are conducted to verify the advantage of our proposed Fed-CHS in terms of test accuracy, communication overhead saving, and convergence over existing methods.\n\nIn the future, we will extend our theoretical analysis from the setup of single-step local iteration to multi-step, which is more general. And the potential of this setup has been verified in existing experiments on communication overhead."

Both Fed-CHS and Hier-Local-QSGD conduct 20 iterations per round within the cluster.\nIn this subsection, we examine the impact of the number of local communication rounds, the degree of data heterogeneity and the number of ES\u2019s on our proposed Fed-CHS.\nAdditionally, we also examine the impact of partial data heterogeneity within one cluster on Fed-CHS.\nFigure 3(a)  ###reference_sf1### and Figure 3(d)  ###reference_sf4### show that our Fed-CHS\u2019s convergence rate varies with the number of local communication rounds.\nIn case a smaller  is adopted, which implies a higher learning rate, a faster convergence rate can be achieved.\nAccording to Theorem 4.3  ###reference_theorem3###, the gap of convergence is weakly affected by , the influence of which is even weaker as  grows. This explains the fact that the training accuracy trends to be similar as  increases.\nBoth Figure 3(b)  ###reference_sf2### and Figure 3(e)  ###reference_sf5### reveal that severe data heterogeneity may exert influence on the training accuracy significantly.\nBut as the dataset distributions among clients tend to be more homogeneous, this kind of influence is likely to decay.\nAs a comparison, the difference of training accuracy due to data homogeneity is more sensitive to convex loss function, like in MLP, rather than a non-convex loss function, like in LENET.\nFigure 3(c)  ###reference_sf3### and Figure 3(f)  ###reference_sf6### clearly illustrate that too many ES\u2019s may lead to a bad performance.\nThe reason can be explained as follows: With the population of clients unchanged but the number of ES\u2019s increased, each ES shares a less fraction of clients, which leads to a less generality of the locally trained model within one cluster.\nSequential updating of this kind of model among clusters become a repetitive correcting process of the model only being adapt to the dataset of the clients in currently active cluster, rather than an evolving process of the model that can represent the global data distribution of all the clients.\n###figure_5### ###figure_6### ###figure_7### ###figure_8### ###figure_9### ###figure_10### We also inspect the training performance of Fed-CHS under fully or partially heterogeneous dataset by using LENET model and CIFAR-10 dataset in Figure 4  ###reference_###.\nWhen partial data heterogeneity is implemented, the dataset distribution among clusters are IID but the dataset distribution among clients within any cluster is non-IID.\nThe extent of heterogeneity is still tuned by parameter .\nAs of training performance, both test accuracy and training loss are probed.\nFrom Figure 4  ###reference_###, we observe that the performance gap due to the difference between fully and partially heterogeneous datasets trends to be diminish as  grows.\nAlso considering the remark in Remark 4.4  ###reference_theorem4###, we can achieve stationary point for non-convex loss function like the LENET model with partially heterogeneous dataset. Then it can be inferred that the performance of Fed-CHS for training a non-convex loss function under fully heterogeneous dataset can be also promised.\n###figure_11### ###figure_12###"

In the combinational framework of HFL and SFL, every RSU acts as the ES and the bypassing vehicles are participating clients. Once get the aggregated local model from bypassing vehicles, one RSU can push it to the neighbor RSU for next round of iteration. Through this operation, no data transmission is required from neither any vehicle nor a RSU to a central PS round by round. Lost of traffic burden is saved in the hybrid framework of HFL and SFL.\nAn illustrative figure of this scenario is given in Figure 8  ###reference_###\n111Thanks for the courtesy of Freepik.com, which offers parts of the elements for Figure 8  ###reference_### and Figure 9  ###reference_###..\n###figure_25### Integrated Low-earth Orbit (LEO) Satellite-Terrestrial Network:\nIntegrated LEO satellite-terrestrial network can provide seamless and reliable content delivery service for the users widely distributed on earth\u2019s surface. This type of network such as StarLink has been put into use (Zhao et al.,, 2022  ###reference_b60###; Xu et al.,, 2023  ###reference_b53###). To learn a common model from the surface users in a certain area via the FL technique, local model parameters of multiple surface users can be uploaded to the LEO satellite overhead for aggregation (Zhang et al.,, 2020  ###reference_b59###; Letaief et al.,, 2022  ###reference_b21###).\nRestricted by orbit dynamics, every LEO satellite flies over the sky quickly and would not be able to offer the service of parameter aggregation and broadcasting for long.\nTo overcome this challenge, we can adopt the combinational framework of HFL and SFL, in which every LEO satellite above the horizon can be taken as one ES and the surface users correspond to participating clients.\nWithin such a framework, the LEO satellite with the most up-to-date model parameter but has to go below the horizon soon can hand over its model parameter to the LEO satellite arising in the sky.\nThrough this way, parameter aggregation and broadcasting can be sustained round by round between the surface users and the LEO satellites over the sky.\nThis application scenario is demonstrated in Figure 9  ###reference_###.\n###figure_26###"

However, most methods suffer from the following issues: 1) an over-reliance on meticulously designed data augmentation strategies, which can undermine the potential of contrastive learning. 2) overlooking cluster-oriented structural information, particularly the higher-order cluster(community) structure information, which could unveil the mesoscopic cluster structure information of the network. In this study, Structure-enhanced Contrastive Learning (SECL) is introduced to addresses these issues by leveraging inherent network structures. SECL utilizes a cross-view contrastive learning mechanism to enhance node embeddings without elaborate data augmentations, a structural contrastive learning module for ensuring structural consistency, and a modularity maximization strategy for harnessing clustering-oriented information. This comprehensive approach results in robust node representations that greatly enhance clustering performance. Extensive experiments on six datasets confirm SECL\u2019s superiority over current state-of-the-art methods, indicating a substantial improvement in the domain of graph clustering.",

This segmentation yields insights into the network\u2019s structure and is crucial for applications in social networking, biology, and recommendations [1  ###reference_b1###, 2  ###reference_b2###, 3  ###reference_b3###]. However, when faced with complex graph data that includes high-dimensional attribute information, it presents a challenge in effectively processing the graph data. Traditional methods, such as those based on sequences [4  ###reference_b4###, 5  ###reference_b5###], non-negative matrix factorization [6  ###reference_b6###, 7  ###reference_b7###], and spectral clustering [8  ###reference_b8###, 9  ###reference_b9###], only utilize the structural information of the graph. Methods based on attribute clustering [10  ###reference_b10###, 11  ###reference_b11###] only use attribute information. This exclusive focus on one type of data, either structure or attributes, can reduce the performance of clustering.\nThe advent of Graph Neural Networks (GNNs) enables the simultaneous processing of attribute and structural information. With their advanced graph representation learning capabilities, several GNN-based methods [10  ###reference_b10###, 12  ###reference_b12###, 13  ###reference_b13###] have been proposed for graph clustering. End-to-end graph clustering methods have been developed that directly yield clustering outcomes to learn embeddings with a clustering tendency [14  ###reference_b14###, 15  ###reference_b15###, 16  ###reference_b16###]. Additionally, to address the issue of over-smoothing, SDCN [17  ###reference_b17###] combines GAE with standard autoencoders, forming a unified framework to capture higher-order structural information. Although these methods are effective for graph clustering, their dependence on accurately initialized cluster centers may result in a tedious and inefficient pre-training process.\nTo address the aforementioned issues, contrastive learning, as a self-supervised learning method, substitutes the cluster update optimization loss with a contrastive loss, thus mitigating the manual trial-and-error problem. Inspired by this, a series of graph clustering methods grounded in contrastive learning have been proposed [18  ###reference_b18###, 19  ###reference_b19###, 20  ###reference_b20###, 21  ###reference_b21###, 22  ###reference_b22###, 23  ###reference_b23###, 24  ###reference_b24###], achieving noteworthy performance. However, we observe that these methods exhibit two primary issues: 1) The success of contrastive learning is heavily contingent upon carefully selected graph data augmentations. Inappropriate graph data augmentations, including random attribute perturbation or random edge dropping, may induce semantic drift, compromising the integrity of the learned embeddings. 2) They overlook clustering-oriented information, particularly the higher-order cluster(community) structure information, which could unveil the mesoscopic cluster structure information of the network. The mesoscopic cluster structure pertains to the organization of the graph at an intermediate level, bridging the local structure captured by individual node connections and the global structure of the entire graph.\nTo address these issues, we propose a novel method termed Structure-enhanced Contrastive Learning for Graph Clustering (SECL). Eschewing complex data augmentation techniques for graph perspectives, we leverage the inherent network structure, obviating the necessity for carefully designed data augmentation. We construct two perspectives through the generation of attribute and structural encodings that respectively capture the graph\u2019s attribute and structural information. A cross-view contrastive loss is introduced to learn more discriminative node embeddings by contrasting graph representations under different views. To reinforce structural information, a structural contrastive loss is employed, aiming to align the cross-view similarity matrix with the self-looped adjacency matrix. Finally, to advance the model\u2019s assimilation of clustering-oriented information, we devised a modularity maximization loss function. This loss function motivates the model to optimize embeddings so as to reflect the cluster (community) structure within the graph. In summary, the principal contributions of this study are as follows:\nWe propose a novel Structure-Enhanced Contrastive Learning (SECL) approach that aims to improve the performance of graph clustering tasks without the need for pre-training and carefully designed data augmentation. The core of this method lies in directly extracting valuable information from the graph structure itself and utilizing this information to enhance the model\u2019s learning process.\nWe combine contrastive learning with modularity optimization for the task of graph clustering. This approach aims to enhance the model\u2019s ability to recognize community structures in graphs through the framework of contrastive learning. By this integration, the model can learn representations by leveraging both the similarities between nodes and the overall community structure of the graph.\nExtensive experimental results on six different domain datasets demonstrate the superiority of SECL over state-of-the-art graph clustering methods."

This methodology is essential for uncovering the underlying structure of complex networks. The growing importance of graph clustering has garnered significant attention from the research community, leading to the development of numerous algorithms tailored for this purpose [25  ###reference_b25###, 3  ###reference_b3###].\nLearning high-quality embeddings for graph clustering is crucial; traditional graph embedding methods [4  ###reference_b4###, 5  ###reference_b5###, 26  ###reference_b26###, 27  ###reference_b27###, 28  ###reference_b28###] often overlook the attribute or structural information of networks. However, thanks to the development of Graph Convolutional Neural Networks (GCNs), these tools incorporate both the attribute and structural information of networks to learn node embeddings. Kipf et al. [29  ###reference_b29###] introduced the GAE and VGAE models, employing autoencoders to reconstruct adjacency matrices and facilitate graph embedding. Building on this, MGAE [30  ###reference_b30###] refines the GAE approach by enhancing the embedding process. In a related vein, ARGA and ARVGA [12  ###reference_b12###] leverage these graph autoencoders to effectively extract embedding information. Furthering the development of these models, AGC [13  ###reference_b13###] utilizes higher-order graph convolutions to identify global clustering patterns. Addressing the common issue of over-smoothing in such models, SDCN [17  ###reference_b17###] integrates the principles of GAE with standard autoencoders, creating a cohesive framework that captures higher-order structural data. The DAEGC [14  ###reference_b14###] algorithm takes advantage of an attention network to assign weights to nodes, optimizing for both reconstruction loss and KL-divergence-based clustering loss. In a similar context, CDBNE [15  ###reference_b15###] uses a graph attention mechanism to process topology and node attributes, aiming to adeptly identify community structures within networks by maximizing modularity. DDGAE [16  ###reference_b16###] integrates high-order modularity information and attribute information as distinct views and learns the latent node representations through the reconstruction of topology, attribute, and modularity information.\nWhile the previously mentioned graph clustering techniques are proficient, their dependency on accurately initialized cluster centers for optimal performance can result in a laborious and inefficient trial-and-error pre-training process [12  ###reference_b12###, 14  ###reference_b14###, 17  ###reference_b17###, 31  ###reference_b31###]. In contrast, the application of contrastive learning alters this dynamic, as it substitutes the traditional cluster update optimization loss function with a contrastive loss. This innovative approach negates the necessity for manual trial-and-error pre-training."

SimCLR [32  ###reference_b32###] constitutes a significant advancement in representation learning, aligning augmented versions of the same data instances to achieve maximum concordance. Extending beyond, GraphCL [18  ###reference_b18###] introduces four novel graph-specific augmentations that enhance unsupervised graph representation learning. GCA [20  ###reference_b20###] refines this method with an adaptive augmentation technique that adjusts to the unique structure and attributes of each graph. MVGRL [21  ###reference_b21###] leverages diffusion processes to generate diverse graph views, improving representation learning quality. SCAGC [33  ###reference_b33###] alters the graph topology by randomly adding or removing edges. GDCL [22  ###reference_b22###] combines graph diffusion with an innovative use of signal smoothness to guide its contrastive learning, while DCRN [23  ###reference_b23###] employs a siamese network structure focusing on the nuanced hierarchical features in graph node representations. Despite their effectiveness, these approaches rely on dependable data augmentation for positive pair identification. Shifting towards more sophisticated strategies, CCGC [34  ###reference_b34###] and SCGC [24  ###reference_b24###] produce dual augmented vertex views via distinct siamese encoders, representing a departure from conventional augmentation techniques.

As shown in Figure 4  ###reference_###, SECL demonstrates strong performance with  values between 2 and 3.\n###figure_14### Moreover, our model becomes less sensitive to variations in  for values in the range . In Figure 5  ###reference_###, we observe that SECL achieves optimal performance with  on the BAT, CITESEER, and AMPA datasets, while it performs best with  on the other datasets. This indicates that our approach does not necessitate deep MLPs, effectively reducing the overall number of model parameters.\n###figure_15###"

From the figure, it can be seen that our SECL method has achieved better performance compared to other methods, is able to reveal the underlying cluster structure more effectively. Compared to other algorithms, the clustering visualization results obtained from DAEGC display greater inter-cluster distances. This can be attributed to the utilization of KL divergence.

By utilizing inherent graph structures and attributes with two MLPs, SECL effectively obviates the need for pre-training and complex data augmentation. Then, a cross-view contrastive loss is proposed to enhance the discriminative capability of the node representations. Next, within the structure contrastive loss module, consistency of structure information is ensured by aligning the similarity matrix with the neighboring structure information. Finally, a modularity maximization module is employed to capture cluster-oriented information. Experimental results have confirmed the superiority of SECL over existing methods, demonstrating its ability to discern complex community structures within graphs. Our ablation studies have underscored the importance of each proposed module, while visualizations of the clustering results have offered intuitive evidence of the method\u2019s effectiveness. Despite a marginal increase in computational cost compared to the fastest baseline, the performance gains of SECL warrant its use. The success of SECL indicates a promising avenue for future research in graph clustering, with potential for extending to more complex networks and real-world applications. Hence, in future research, we aim to extend this method and develop new deep graph clustering models capable of handling large-scale and dynamic graph data."

Subsequently, the similarity between the attribute and structure embeddings is computed to derive the cross-view contrastive loss. Next, within the structure contrastive loss module, consistency of structure information is ensured by aligning the similarity matrix with the neighboring structure information. Then, a modularity maximization module is employed to capture cluster-oriented information. Finally, we jointly optimize the cost functions of three modules using the Adam optimizer.

+    "abstract": "Converting different modalities into generalized text, which then serves as input prompts for large language models (LLMs), is a common approach for aligning multimodal models, particularly when pairwise data is limited. Text-centric alignment method leverages the unique properties of text as a modality space, transforming diverse inputs into a unified textual representation, thereby enabling downstream models to effectively interpret various modal inputs. This study evaluates the quality and robustness of multimodal representations in the face of noise imperfections, dynamic input order permutations, and missing modalities, revealing that current text-centric alignment methods can compromise downstream robustness. To address this issue, we propose a new text-centric adversarial training approach that significantly enhances robustness compared to traditional robust training methods and pre-trained multimodal foundation models. Our findings underscore the potential of this approach to improve the robustness and adaptability of multimodal representations, offering a promising solution for dynamic and real-world applications.",

+            "text": "Text-centric multimodal alignment methods have emerged as a powerful approach for integrating multimodal information by converting diverse data types into text. This technique leverages the unique properties of text as a universal modality space, enabling large language models (LLMs) to process and understand visual, auditory, and other forms of data, and have shown competetive performance compared to other traditional embedding-based alignment methods (Tsai et al. 2024a  ###reference_b35###). By transforming non-textual information into textual descriptions, these methods facilitate the alignment and integration of various modalities, enhancing the capability of LLMs to comprehend and generate contextually rich responses.\nFor example, LLaVA (Liu et al. 2023c  ###reference_b29###) uses expert models to generate captions, object detection locations, and textual descriptions from images. These are then used as input to GPT-4 to create vision-text instruction-following data as a substitute of actual collecting vision-text instruction-following data, which is inherently difficult and resource-intensive to obtain.\n###figure_1### Recent study (Wang et al. 2023b  ###reference_b27###) discovered that Vision LLMs trained on pure synthetically generated high-quality captions by image caption models to replace original noisy data fall into model collapse (Robinson et al. 2021  ###reference_b7###). This phenomenon can be explained by captioning collapse (Vinyals et al. 2015  ###reference_b2###; Wang, Zhang, and Yu 2020  ###reference_b6###) and the one-to-many problem (Young et al. 2014  ###reference_b1###) in image captioning. That is, when transforming images into text, it generates fixed or similar captions for different images, which limits diversity in the output and could potentially jeopardize the downstream model training. This could cause the learned multimodal representations to be less robust for discriminative models (ex. classifier) and cause modality collapse issue for generative models (ex. MLLMs). This leads to the concern where text-centric alignment method would be lead to less robust performance.\nIn this paper, we improve the modality robustness in text-centric modality alignment methods. Specifically, we aim to repair the modal collapse issue when transforming various modalities into text leads to the generation of fixed or similar outputs, resulting in information loss and reduced diversity. This, in turn, compromises the robustness of the learned multimodal representation.\nWe further propose using adversarial prompting (Yang et al. 2024  ###reference_b34###; Dong et al. 2023  ###reference_b24###; Xu and Wang 2024  ###reference_b32###) and formulate a text-centric adversarial training approach to enhance the modality robustness of text-centric multimodal alignment. Before converting different input modalities into text using expert models and align these modalities within a similar semantic space, we applied a LLM-based perturbation module on top and increase the diversity and robustness of text representations. This adversarial training procedure along with multimodal alignment will optimizes for a more robust performance. This can be easily understand as using LLMs as an adversary to force improve the robustness of multimodal alignment and the downstream model.\nIn our experiment, different input modalities are converted into text descriptions using expert foundation models for each modality.\nTo evaluate the robustness of these representations, we follow the MULTIBENCH (Liang et al. 2021  ###reference_b8###) framework, which introduces varying levels of and imperfections. This approach simulates real-world conditions, allowing us to assess how well our unified textual representations perform under scenarios of missing or noisy data.\nBy rigorously testing under these conditions, we demonstrate that our enhancement can significantly improve the modality robustness. Qualitative analysis also shows that modality summarization and reasoning augmentation with LLMs offer significant advantages: 1) recovering dropped or corrupted information, 2) transforming implicit relationships into explicit text descriptions, and 3) compensating missing information using LLMs as external knowledge sources. These enhancements contribute to the overall robustness and utility of the multimodal representations.\nOur contributions are summarized as follows:\nWe are the first to investigate modality robustness in text-centric alignment methods, revealing their inherent lack of robustness.\nWe propose an text-centric adversarial training to enhance the robustness for text-centric alignment that demonstrates effective enhancement to modality robustness, consistently outperforming the baselines including traditional robust training methods and multimodal foundation models.\nWe provide a qualitative analysis illustrating how large language models (LLMs) strengthen the robustness of textual representations in multimodal alignment.\n###figure_2###"

These perturbations can include noise injection, information dropout, and order permutation, each of which is intended to disrupt the model\u2019s understanding and push its predictions toward incorrect labels.\nOur approach begins with the pre-generation of a diverse set of instruction prompts specifically tailored for adversarial purposes. These prompts are crafted to induce the LLM to generate adversarial examples that effectively simulate challenging and unpredictable scenarios. The adversarial perturbations are applied modality-wise, allowing us to evaluate and enhance the robustness of the model across different modalities.\nTo systematically generate adversarial examples, we follow these steps:\nRandom Initialization: We begin by applying random perturbation to the original input  to create an initial variation . This step ensures that the base input is already altered before applying further adversarial instructions, increasing the likelihood of generating a significantly misleading example.\nInstruction Selection and Parameterization: An instruction prompt  is selected from our pre-generated set, which may direct the LLM to perform tasks such as adding noise, dropping critical information, or permuting the order of elements within the input. Alongside the instruction, we set the temperature parameter  to control the randomness of the LLM\u2019s output.

+    "abstract": "This paper delves into the emerging field of face-based voice conversion, leveraging the unique relationship between an individual\u2019s facial features and their vocal characteristics.\nWe present a novel face-based voice conversion framework that particularly utilizes the average fundamental frequency of the target speaker, derived solely from their facial images.\nThrough extensive analysis, our framework demonstrates superior speech generation quality and the ability to align facial features with voice characteristics, including tracking of the target speaker\u2019s fundamental frequency.",

+            "text": "Voice, the cornerstone of human speech, plays a crucial role in interpersonal communication. Beyond its communicative function, voice is a distinctive feature of an individual, reflecting personal identity.\nConsequently, individuals who are unable to produce sound not only face a significant barrier to communication but also experience a loss of personal expression.\nConventional speech synthesis techniques, such as Text-to-Speech (TTS) and Voice Conversion (VC), have made significant strides in emulating a target voice while retaining the non-verbal content elements. Yet, these techniques predominantly rely on the availability of the target voice\u2019s acoustic data to replicate its unique speech style effectively.\nThe human face represents another intrinsic aspect of individual identity, containing details such as biological gender, ethnicity, and age. More than just exploring visual information from face, recent studies have increasingly focused on understanding the relationship between facial features and vocal attributes [1  ###reference_b1###, 2  ###reference_b2###]. This field of study may hold the key to a new form of speech synthesis, one that retains the target speaker\u2019s identity even in the absence of vocal information.\nRecent advancements in face-based speech synthesis have experienced a notable surge, particularly through the integration of conventional TTS [3  ###reference_b3###, 4  ###reference_b4###, 5  ###reference_b5###, 6  ###reference_b6###] and VC [7  ###reference_b7###, 8  ###reference_b8###, 9  ###reference_b9###] techniques. While this growing interest and development show a promising view, the field remains in its formative phases. Specifically, identifying a \u2018voice that matches the face\u2019 presents significant challenges, and metrics for evaluating it also remain a pivotal question.\nThe fundamental frequency (), one of the key components in voice conversion process [10  ###reference_b10###, 11  ###reference_b11###], not only serves as a pitch information of speech but also has an aspect of containing information of speakers identification [12  ###reference_b12###].\nIt has been found that facial features have correlation with voice pitch information, even in cases where gender is controlled [1  ###reference_b1###].\nIt implies that voice pitch information, indicated by the , could be derived from the speaker\u2019s facial images, and it is not merely from basic gender identification, but also from further biological associative information.\nIn this study, we propose a novel framework for face-based speech synthesis, focusing particularly on the voice conversion that imprints a face-based target voice\u2019s characteristics onto the original source audio. Our framework specifically utilize the  of target speaker, derived solely from facial images. This approach aims to enhance the face-based voice conversion process, generating speech that is well aligned with the target individual\u2019s vocal identity without using any acoustic data of the target speaker.\nTo contextualize our research, we delineate our contributions as follows:\nWe present a framework that sets a new benchmark in performance for face-based voice conversion, demonstrating state-of-the-art results.\nWe propose a novel approach for speech synthesis by estimating the  of the target speaker through their facial images.\nThrough extensive analysis and the introduction of a novel evaluation metric, we demonstrate that our framework not only produces high-quality synthetic speech but also suggests that the synthesized voice aligns reasonably well with the corresponding facial image.\nThe demo is available on the link, https://jaejunL.github.io/HYFace_Demo/  ###reference_###."

To address this, various methodologies have been explored, including adversarial training [13  ###reference_b13###, 14  ###reference_b14###], vector quantization [15  ###reference_b15###, 16  ###reference_b16###], and information perturbation [10  ###reference_b10###, 11  ###reference_b11###].\n\n###figure_1### (a) Training phase                                                     (b) Inference phase\nNotably, recent advancements have been made with the advent of self-supervised learning (SSL) techniques. Pretrained representations trained on large data corpus exhibit a remarkable capacity for disentangling the contents information of speech [17  ###reference_b17###, 18  ###reference_b18###], thereby significantly enhancing voice conversion processes [19  ###reference_b19###].

Particularly, the authors in [1  ###reference_b1###] showed that humans can significantly match faces and voices under the controlled attributes such as gender, race, and age. Specifically, they also revealed that there is a correlation between the target speaker\u2019s voice pitch and facial features.\nBuilding on these finding, interest has surged in learning based methods for associations between faces and voices. An application of such methods includes generating face from a given speech [2  ###reference_b2###, 23  ###reference_b23###] or vice versa. Specifically, face-based speech synthesis, the focus of this paper, is categorized based on the type of input: text for TTS [3  ###reference_b3###, 4  ###reference_b4###, 5  ###reference_b5###, 6  ###reference_b6###] and source audio for VC [7  ###reference_b7###, 8  ###reference_b8###, 9  ###reference_b9###, 24  ###reference_b24###].

We used predefined pretrain, trainval and test set for training, validation and evaluation, respectively. Expecting our proposed model to more carefully associate detailed face features with speaker\u2019s voice characteristics, we used only frontal images from the dataset. Especially, we employed OpenCV haarcascades444https://github.com/opencv/opencv/tree/master/data/haarcascades for image selection, resulting in about 20% of image data being filtered out.\nFor the evaluation, we picked 50 male and 50 female speakers on test set, ranked by the amount of data available. On average, there are about 5.8 speech audio files and 280 facial images available per speaker.\nWe hypothesized that converting the voice to a target speaker of a different gender from the source is more challenging than converting to the same gender.\nTherefore, we constructed two types of evaluation sets: Homogeneous Gender (HMG) set and Heterogeneous Gender (HTG) set. The HMG set pertains to face-based voice conversion scenarios in which the target speaker\u2019s gender is the same as the source speaker\u2019s (either male to male (M2M) or female to female (F2F)). In contrast, the HTG set applies to scenarios where the target speaker\u2019s gender is different from that of the source speaker (from male to female (M2F) or female to male (F2M)).

For subjective evaluation, we examine subjective consistency, naturalness, and ABX tests. Furthermore, we propose a new evaluation metric: pitch deviation. For all objective evaluations, we randomly selected 10 source speakers for each of the 50 target speakers and repeated this process for 10 trials. This resulted in a total of 5,000 conversion pairs for each of the four evaluation sets. To measure cosine similarity, we utilized speaker embeddings generated by Resemblyzer555https://github.com/resemble-ai/Resemblyzer. For subjective evaluations, we use Mean Opinion Scores (MOS) collected via Amzon Mechanical Turk (MTurk). We described detailed procedure of MTurk on Supplementary B. The explanation of each metric is as follows.\nHomogeneity: It measures cosine similarity of speaker embeddings in synthesized audio generated from different facial images of the same speaker.\nSimilarity value is expected to be high regardless of different view of face image on same speaker. We randomly select 10 face images from each target speaker.\nDiversity: It measures cosine similarity of speaker embeddings in synthesized audio generated from different speakers. In contrast from homogeneity, here the model aims to capture distinct speaker information for different target speakers.\nConsistency(obj): It compares the speaker embedding similarity of the synthesized audio with that of the ground-truth audio from the same speaker. To ensure a robust comparison, we also assess this metric with ground-truth audio from a random speaker, referred to as \u2018Consistency(rnd)\u2019.\nConsistency(sub): This metric measures consistency for subjective evaluation using a 5-point MOS scale (completely inconsistent to completely consistent). It assesses whether the synthesized audio aligns with the corresponding facial images.\nNaturalness: It assesses the sound quality of the synthesized audio using 5-point MOS scale (completely unnatural to completely natural).\nABX test: This evaluates the subjective preference between two models. Participants are shown a face image and asked to decide which of two synthesized audio samples, one from HYFace and the other from FVMVC, more closely matches the face in the image.\nPitch deviations: It is our newly proposed metric. Since the  is one of the key component of voice, we assess the deviation between the  of the synthesized audio and the average  (represented as  in Section 3  ###reference_###) of the ground-truth target speaker.\nNote that the standard deviations (stdv) of the  for all audio samples are 29.18 Hz for male speakers and 37.50 Hz for female speakers. These values serve as a baseline, reflecting the deviation is based solely on gender class.

In fact, scientific ML is currently being used to build accurate and efficient surrogate models starting from high-fidelity numerical simulations, effectively encoding the parameterized temporal dynamics underlying Ordinary Differential Equations (ODEs), or even the spatio-temporal behavior underlying Partial Differential Equations (PDEs), in appropriately designed neural networks.\nWe propose an extension of Latent Dynamics Networks (LDNets), namely Liquid Fourier LDNets (LFLDNets), to create parameterized space-time surrogate models for multiscale and multiphysics sets of highly nonlinear differential equations on complex geometries.\nLFLDNets employ a neurologically-inspired, sparse, liquid neural network for temporal dynamics, relaxing the requirement of a numerical solver for time advancement and leading to superior performance in terms of tunable parameters, accuracy, efficiency and learned trajectories with respect to neural ODEs based on feedforward fully-connected neural networks.\nFurthermore, in our implementation of LFLDNets, we use a Fourier embedding with a tunable kernel in the reconstruction network to learn high-frequency functions better and faster than using space coordinates directly as input.\nWe challenge LFLDNets in the framework of computational cardiology and evaluate their capabilities on two 3-dimensional test cases arising from multiscale cardiac electrophysiology and cardiovascular hemodynamics.\nThis paper illustrates the capability to run Artificial Intelligence-based numerical simulations on single or multiple GPUs in a matter of minutes and represents a significant step forward in the development of physics-informed digital twins.",

[Regazzoni2024], define a novel architecture to create surrogate models for parameterized physical processes, such as those arising from systems of differential equations.\nLDNets jointly discover a low-dimensional nonlinear manifold while learning the spatio-temporal system dynamics, avoiding operations in the high-dimensional space.\nLDNets achieve higher accuracy on highly nonlinear mathematical problems with significantly fewer trainable parameters compared to both intrusive and non-intrusive state-of-the-art methods based on proper orthogonal decomposition, autoencoders, and various types of recurrent neural networks [Regazzoni2024].\nIn this paper, we propose an extension of LDNets, namely Liquid Fourier LDNets (LFLDNets), as an effective operator learning method that demonstrates superior performance in terms of number of tunable parameters, expressiveness, interpretability, overall accuracy and computational efficiency during training and inference.\nLFLDNets use a simple and compact Liquid Neural Network (LNN) instead of a feedforward Fully-Connected Neural Network (FCNN) to track the temporal dynamics of a set of states, capturing the global behavior of highly nonlinear parameterized multiscale PDEs.\nFurthermore, they use a Fourier embedding with a learnable kernel matrix for space coordinates, so that a second FCNN reconstructs the entire space-time dynamics of the PDE system by properly capturing complex functions.\nWe demonstrate the capabilities of LFLDNets on two challenging 3D patient-specific cases arising in computational cardiology [Niederer2019Nature].\nWe first build multiscale surrogate models for cardiac electrophysiology [Salvador2024DTCHD] in a complex pediatric congenital heart disease model and second simulate cardiovascular hemodynamics in a healthy pediatric aorta [Updegrove2017].\nThese geometries are spatially discretized with a fine unstructured tetrahedral grid; the hemodynamics case also contains anisotropic element refinement within the boundary layer.\nFurthermore, we demonstrate that even in these complex scenarios, LFLDNets allow for time steps that are orders of magnitude larger than those commonly used in physics-based simulations due to the constraints introduced by the specific numerical discretization scheme.\nThis work introduces a new scientific ML tool, namely LFLDNets, and demonstrates its potential in two realistic examples from computational medicine.\nDuring inference, LFLDNets produce, within some tolerance, results equivalent to 3D space-time cardiovascular simulations in a matter of minutes on one or multiple Graphics Processing Units (GPUs) while spanning different sets of model parameters, initial, and boundary conditions.\nThis tool defines another contribution to building complex multiscale and multiphysics spatio-temporal surrogate models to create accurate, efficient and certified digital replicas for cardiovascular applications [CorralAcero2020, Fedele2023, Gerach2021, Jung2022, Gillette2021, Salvador2024DTCHD, Salvador2024EMROM4CH, Viola2023]."

Furthermore, CfCs are as expressive as neural ODEs, while requiring fewer tunable parameters, thus maximizing the trade-off between accuracy and efficiency [Hasani2022CfC].\nWe use the LeCun hyperbolic tangent activation function for all layers of the  dynamics network.\nMoreover, we do not employ any backbone units, that is we learn ,  and  separately without any shared representations [Hasani2022CfC]."

consider for tuning, along with the final set chosen by the Bayesian optimizer.\nWe see that the optimal LFLDNet is compact, with less than a million tunable parameters.\nThis is remarkable given the complexity of the 3D multiscale electrophysiology simulations encoded by this surrogate model.\nTraining LFLDNets for hyperparameter tuning over 500 epochs takes from 10 minutes to 5 hours, depending on the specific architecture.\nThe optimal configuration achieves convergence at epoch 1.799 after 1 hour and 30 minutes of computation.\nSpecifically, the normalized MSEs for the training (100 simulations) and validation (50 simulations) sets are 9.12e-4 and 3.15e-3, respectively, at epoch 1.799.\nRunning inference over the whole spatio-temporal numerical simulation requires 3 minutes in eager mode.\nOn the other hand, a high-fidelity simulation takes about 1.5 hours on 24 cores.\nIn Figures 2  ###reference_### and 3  ###reference_### we depict the spatio-temporal evolution of the action potential and the pointwise absolute errors over the cardiac cycle at different time points for a random sample of the validation set, respectively.\nWe show good agreement between the LFLDNets prediction and the original numerical simulation throughout the heartbeat, especially with respect to the overall propagation pattern and conduction velocities.\nThe pointwise absolute error remains uniformly small over the cardiac cycle and increases only locally in correspondence with the wavefront during some instances of the depolarization and repolarization phases, which exhibit steep gradients.\nWe also note that the uniform time step chosen for training and inference, i.e.  ms is orders of magnitude larger than the maximum time step allowed in the Finite Element simulations of the monodomain equation coupled with the ten Tusscher-Panfilov ionic model, due to stiffness, convergence and stability requirements.\nFurthermore, this test case presents bifurcations in the parameter space, as the simulated behavior ranges from sinus rhythm, which is a healthy propagation pattern, to different stages of bundle branch block, which is a pathological condition.\nAs mentioned in the Methods section, all LFLDNets operations are performed on 1 Nvidia A40 GPU.\nIn Figure 4  ###reference_### we compare the performance of LFLDNets with their original LDNet and LLDNet counterparts, i.e. LFLDNets without the Fourier embedding.\nWe perform hyperparameter tuning for both LDNets and LLDNets using the same ranges of Table 3  ###reference_###.\nWe see that both architectures require larger neural networks than the optimal LFLDNet, which consists of 200 neurons for the dynamics network, 10 hidden layers with 200 neurons per layer for the reconstruction network.\nSpecifically, the optimal LDNet has 10 hidden layers with 450 neurons per layer for both networks, whereas LLDNet presents 300 neurons for the dynamics network, 10 hidden layers with 300 neurons per layer for the reconstruction network.\nWe remark that CfC, NCPs have a fixed number of hidden layers, which is set to 4, and the only tunable hyperparameter is given by the total amount of neurons, which is divided into sensory, inter, command, and motor neurons according to the specified number of inputs and states.\nWe also notice that the optimal dimension of the state vector is 150 for LDNet and 50 for LLDNet/LFLDNet, resulting in a smaller state representation for the liquid counterpart.\nFurthermore, the lighter LFLDNet manifests faster convergence and lower normalized MSEs from the very first epochs.\nTraining the optimal LDNet, LLDNet and LFLDNet for 500 epochs takes approximately 30, 40 and 50 minutes, respectively.\nIn Figure 4  ###reference_### we also perform a convergence study in terms of the dimension of the Fourier features, where we show that larger embeddings are associated with better convergence to smaller normalized MSEs.\nHowever, this comes at the cost of more expensive training and slightly higher memory requirements to store a larger Fourier embedding.\nIn Figure 5  ###reference_### we compare LDNets, LLDNets and LFLDNets in terms of the state vector  temporal dynamics for a random sample of the validation set.\nWe see that 150 LDNets states mostly exhibit stretched and compact trajectories, whereas 50 states for both LLDNets and LFLDNets show smooth trajectories that are varying throughout the heartbeat according to the features of the cardiac electrophysiology simulation and cover more uniformly the bounded [-1, 1] non-dimensional range.\nThis motivates why the optimal architectures for LLDNets and LFLDNets have a lower number of states than LDNets.\nOverall, we show that LFLDNets demonstrate superior performance in terms of number of tunable parameters for the dynamics and reconstruction networks, generalization errors, state vector temporal dynamics, training and inference times with respect to LDNets."

the spatio-temporal dynamics of parameterized time-dependent PDEs.\nWe considered two challenging 3D test cases in computational cardiology to show their advantages and features, and assess performance.\nLFLDNets uses a CfC, NCP dynamics network to define the time evolution of a global state vector characterizing the dynamical system [Hasani2022CfC, Lechner2020NCP].\nUnlike neural ODEs, LNNs exploit a closed-form solution of the ODE system and let the state vector evolve without a specific temporal discretization scheme.\nFurthermore, these sparse neural networks are at least an order of magnitude faster and more expressive than neural ODEs, while requiring fewer tunable parameters than other fully-connected architectures, thus providing improved accuracy and computational efficiency [Chen2019, Hasani2022CfC].\nSimilar to LDNets, the second component of LFLDNets is made by a FCNN, called reconstruction network, to recover a generic space-time field of interest [Regazzoni2024].\nHowever, in LFLDNets, the spatial coordinates provided as input to the reconstruction network are fed into a trainable Fourier encoding so as to prioritize the learning of high-frequency functions over smooth features during training.\nThis allows the model to represent a wider range of frequency content than prior methods with a slight increase in computational cost.\nCfC, NCP dynamics networks provided superior convergence during training along with smooth temporal dynamics that is also broader, better distributed, and more representative of the physical system compared to the neural ODE counterpart.\nIn fact, as also observed in [Lim2024, Salvador2024BLNM], enforcing sparsity and breaking symmetries in the inherent structure of a neural network played a crucial role in the optimization process to determine a smoother landscape of local minima and a more monotonic decay of the loss function.\nThe generalization error decreased as the dimensionality of the Fourier embedding increases.\nAs shown in [Regazzoni2024], a similar trend can also be observed when increasing the number of states.\nWe also found that increasing the number of Fourier frequencies allowed us to obtain a faster decay of the loss function, which also start from lower values since the very first epochs, at the expense of having a larger input layer in the reconstruction network combined with a larger Fourier embedding.\nIn terms of activation functions, the use of LeCun hyperbolic tangent in the dynamics network and GELU in the reconstruction network resulted in a better and smoother decay of the loss function than pure hyperbolic tangent in both neural networks.\nFor the architectures explored in this paper, these relaxed the need for a learning rate scheduler in the Adam optimizer and corresponding hyperparameter tuning during the training phase.\nUnlike LDNets, the use of the first-order stochastic Adam optimizer alone achieved low generalization errors and did not hinder convergence with respect to its combination with a second-order deterministic optimizer, such as L-BFGS [Liu1989], which would also have been particularly challenging and expensive during training for the architectures of this paper, which are on the order of a million of tunable parameters.\nWe also observed a negligible performance loss when switching from double-precision to single-precision training.\nWith respect to LDNets, this allowed us to speed up the computation and reduce the memory requirements, which is especially important for GPU training and bigger neural networks.\nHowever, we remark that all wall times reported in this paper refer to eager mode execution.\nThis means that there is still room for improvement during training and inference in terms of overall computational time by switching to graph execution.\nWe tried to add physics-based terms, such as the imposition of a divergence-free velocity field in the CFD test case, to the data-driven loss function based on the MSE, but did not observe a significant improvement in accuracy.\nThis is motivated by the access to the full spatio-temporal numerical solution during the training phase.\nFurthermore, the summation of a physics-based loss term, which encodes the strong form of a differential equation, involves an additional computational burden where the space and time derivatives are evaluated numerically using automatic differentiation.\nOn the other hand, a non-intrusive scientific ML method provides a faster tool where specific PDEs primal variables can be targeted during training, such as the velocity field but not the pressure in the Navier-Stokes equations, using a standard data-driven loss function that is agnostic to the actual application.\nWe also explored different architectures for the dynamics network.\nThanks to their remarkable generalization properties in many different applications, we tried to use transformers for the dynamics network [Vaswani2017, Li2023Transformers].\nHowever, this method, in its original form, has higher spatio-temporal computational complexity during training and inference compared to LNNs, lack interpretability, which is especially important in computational medicine, and require larger training datasets to show good performance.\nWhile this is generally not a limitation in other domains, such as language or vision, scientific computing may require running complex numerical simulations via high-performance computing, and generating arbitrarily large datasets is often not a viable option.\nNevertheless, if properly trained on large datasets, transformer-based models are better at learning very long temporal sequences than LNNs [Hasani2022CfC].\nMoreover, overparameterized transformer-based neural networks show good out-of-distribution properties after a long training process that goes beyond the classical optimal point where validation loss starts to increase while training loss continues to decrease [Wang2024].\nSimilarly, we tested different reconstruction networks.\nFirst, we considered implicit neural representations with periodic activation functions, but we did not observe better performance than the Fourier embedding [Sitzmann2020].\nSecond, we employed graph neural networks, which generally increased the computational cost during training and inference and did not provide better convergence properties compared to a FCNN.\nNonetheless, further investigation is certainly needed, as this tool can be very flexible in generalizing to different cardiovascular geometries [Pegolotti2024], which is not considered in this work.\nWith respect to other neural operators [Rahman2024, Li2020, Li2023, Hao2023, Lu2021, Vlachas2022, Raonic2023], we showed that LFLDNets are very lightweight and can be seamlessly trained in the physical space on complex geometries.\nThis is not always feasible, such as with Fourier neural operators [Li2021], which require a structured grid and can only work on unstructured meshes by introducing a structured reparameterization in a latent space [Li2023GeoFNO].\nFurthermore, our method allows to span generic sets of initial and boundary conditions, as well as physics-based model parameters, forcing terms, space, time, space-time coefficients underpinning multiscale and multiphysics sets of PDEs."

+            "text": "Structure-preserving neural networks have recently garnered interest among the machine-learning community due to their effectiveness in learning solutions to complex problems from sparse data sets. A neural model is called \u201cstructure-preserving\u201d when it incorporates inductive biases, such as physics or geometry, into either the model architecture or training. This can be achieved by either penalizing non-structure-preserving model candidates in the loss function like when training a physics-informed neural network (Raissi et al., 2019  ###reference_b40###) or by incorporating such structures directly into the neural architecture. The former approach is useful when the structure one wants to enforce is complex, such as a partial differential equation but results in models that are not exactly structure-preserving. The latter approach is useful when the structure is simpler, such as a symplectic structure, and can result in more parameter efficient models that are applicable to a wide range of problems. This latter approach is the focus of this paper.\nIn particular, we address the problem of learning a symplectic mapping from time-series data , where  is an unknown map that generates the data. We assume that  preserves a canonical symplectic structure denoted on the conjugate phase space coordinates  by the closed, non-degenerate, canonical two-form\nSuch a map is called a canonical symplectic transformation, which by definition leaves the symplectic matrix    \ninvariant\nwhere  is the Jacobian matrix of the flow map at the point  and ,  are the  identity and zero matrices, respectively. Canonical symplectic transformations often arise from the solution of a Hamiltonian ordinary differential equation (ODE) of the form\nfor Hamiltonian function . If this is the case, then we call  a Hamiltonian flow or map, which is a subset of symplectic maps.\nThe primary goal of this study is to develop a framework for parameterizing arbitrary Hamiltonian maps  by neural networks that are symplectic by construction. The motivation for learning symplectic dynamics is threefold. First, Hamiltonian systems arise naturally in many physical scenarios, such as chemical reactions, accelerator physics, electrodynamics or ideal mechanical systems, the dynamics of which can be measured and information about the system can be learned. Second, symplectic maps can be used as a building block for learning dynamics of more realistic physical systems. Symplectic maps (or integrators) are one of the cornerstones of geometric numerical methods (Hairer et al., 2006  ###reference_b19###) and are used to solve a wide range of realistic problems in the physical sciences and engineering through their use in composition and splitting methods (e.g., (Tapley et al., 2019  ###reference_b44###, 2022  ###reference_b47###)). There are many examples where structure-preserving neural networks, including symplectic neural networks (SympNets), have been applied, including systems with Poisson structure (Jin et al., 2022b  ###reference_b26###), systems with forces such as dissipation (Eidnes et al., 2023  ###reference_b15###), volume-preserving systems (Baj\u0101rs, 2023  ###reference_b1###) or optimal control (Meng et al., 2022  ###reference_b34###). Third, Hamiltonian flows and dynamical system-based neural networks are beginning to play a useful role in more general machine machine-learning applications such as normalizing flows (Chen et al., 2018  ###reference_b10###), equivariant flows (Rezende et al., 2019  ###reference_b41###), deep neural networks with non-vanishing gradients (Galimberti et al., 2023  ###reference_b17###), generative flows (Toth et al., 2019  ###reference_b49###) or classification problems (Haber and Ruthotto, 2017  ###reference_b18###), to name a few. In fact, it has been recently shown in Zakwan et al. (2023  ###reference_b54###) that Hamiltonian deep neural networks have a universal approximation property for arbitrary maps, which further motivates their useful role outside purely physical systems.\nThe core idea behind our proposed framework is simply to approximate the unknown Hamiltonian as a sum , then construct a symplectic splitting method by composing the exact Hamiltonian flows on each . By leveraging many known results from geometric numerical integration, we can prove a number of interesting properties. These properties as well as our main contributions are briefly summarized:\nWe develop a framework for SympNets and propose several novel SympNet architectures for parameterizing a Hamiltonian flow map that we refer to as P-SympNets, R-SympNets and GR-SympNets.\nWe give universal approximation results for these architectures and others within the proposed framework (Theorem 1  ###reference_orem1###).\nWe give a representation result for linear Hamiltonian systems for P-SympNets (Theorem 2  ###reference_orem2###).\nWe demonstrate that our SympNets are interpretable and are amenable to symbolic regression algorithms using backward error analysis to identify the true Hamiltonian (Section 5  ###reference_###).\nWe develop a Python package that implements the SympNets and symbolic regression algorithms that can be installed via pip install strupnet."

This result was used in Jin et al. (2020  ###reference_b24###) to prove symplectic universality of SympNet architectures of the following form111Throughout the paper we will always use  to denote the exact flow of a Hamiltonian ODE . Furthermore,  will always be used to denote a composition of Hamiltonian flows.\nwhere  and  are trainable functions (e.g., neural networks) depending on either  or  only. The functions  and  can be thought of as symplectic residual neural network layers as they take the form , where  is a symplectic transformation. Since the development of this novel architecture, several other authors propose learning symplectic dynamics with SympNets of the form (3  ###reference_###) (e.g., Chen et al., 2019  ###reference_b12###; Tong et al., 2021  ###reference_b48###; Valperga et al., 2022  ###reference_b52###; Burby et al., 2020  ###reference_b4###; Maslovskaya and Ober-Bl\u00f6baum, 2024  ###reference_b31###; Horn et al., 2023  ###reference_b20###).\nAs Hamiltonian systems are so ubiquitous, several more efficient algorithms for learning symplectic dynamics have since been proposed including (Chen and Tao, 2021  ###reference_b9###; David and M\u00e9hats, 2023  ###reference_b13###; Xiong et al., 2020  ###reference_b53###; Offen and Ober-Bl\u00f6baum, 2022  ###reference_b36###; Chen et al., 2023  ###reference_b11###), however these methods learn the dynamics through maps that are defined implicitly, and hence require solving a set of non-linear equations to infer new dynamics. Although many of these methods yield excellent algorithms for learning symplectic structure, a primary motivation of this study to develop SympNets that can be used as building blocks for more complex neural architectures. Therefore, implicit methods will yield intractable algorithms. For this reason we will focus the discussion only on explicit maps of which there are plenty already available in the aforementioned literature.\nThe common conclusion throughout these studies is that using neural models that are intrinsically symplectic is generally advantageous when the data is also generated by a symplectic processes (e.g., a Hamiltonian ODE). This is largely due to the fact that learning a flow map , in general, involves learning all  components of , whereas assuming canonical symplectic structure in the data uniquely defines the flow map by a single scalar function  that can be learned instead, which significantly reduces the size of the model\u2019s hypothesis space.\nA disadvantage of the SympNets of the form (3  ###reference_###) is that they are less interpretable when the true Hamiltonian is generated by a non-separable Hamiltonian. This is illustrated by the following toy example. We train two SympNets, each with four layers, on a data set generated by a  dimensional Hamiltonian ODE (2  ###reference_###) with . The first SympNet is a G-SympNet (Jin et al., 2020  ###reference_b24###) which is of the form (3  ###reference_###) where  and  are neural networks with one hidden layer and certain activation functions. The second SympNet, proposed in this paper, is called a P-SympNet. Over 50000 training epochs, the G-SympNet reaches an MSE training set loss of about 1e-7. The P-SympNet reaches a training set loss of 1e-16 after about 400 epochs.\n###figure_1### ###figure_2### ###figure_3### ###figure_4### While the G-SympNet yields good predictions for the dynamics, it learns large values for  and  relative to the size of the true Hamiltonian, resulting in layers  and  that map their inputs in large and opposite directions. This can be seen by figure 1(a)  ###reference_sf1### that depicts how a data point  is propagated through the layers of the G-SympNet. This point is important because it means the usual tools available to use from numerical analysis do not converge and is evident in figure 1(b)  ###reference_sf2### by the fact that the learned (inverse modified) Hamiltonian is not close to the true Hamiltonian. The P-SympNet, on the other hand, learns a series of symplectic layers that can be analyzed as though it were a splitting method. This means we can sum up the learned Hamiltonians of the symplectic layers to get an  approximation to the true Hamiltonian. This is called the inverse modified Hamiltonian and will be central to our discussion. Furthermore, we can recover the true Hamiltonian from the inverse modified Hamiltonian by expanding it in its Baker-Cambpell-Hausdorff (BCH) series, which is not possible for the G-SympNet.\nIn fact, the G-SympNet necessarily learns Hamiltonian layers that are large, so that the BCH formula doesn\u2019t converge because if it did, it would learn an inverse modified Hamiltonian close to a separable one, which doesn\u2019t agree with the true solution. Due to this, the parameters of the neural networks are biased away from zero, which makes them difficult to initialize and harder to train. For these and similar problems, the P-SympNet often learns layers that are close to the identity transformation, and hence initializing them with small random numbers is an appropriate inductive bias. This is evident by small arrows in figure 1(a)  ###reference_sf1###, representing near-identiy transformations for each layer of the P-SympNet.\nThis motivates the present paper, which aims to extend and unify many of these SympNets into a common framework using tools from geometric numerical integration. Within this framework, we can also propose several new SympNets of which we present three that we refer to as P-SympNets (polynomial), R-SympNets (ridge) and GR-SympNets (generalized ridge). These SympNets are of the form,\nwhere the main difference from (3  ###reference_###) is that the layers  use information from both  and  simultaneously, allowing for increased expressiveness and interpretability. Instead of relying on the symplectic universality results of (Turaev, 2002  ###reference_b51###) to prove universality of the SympNets, the above framework allows us to leverage the vast body of literature from dynamical systems theory, namely geometric numerical integration (Hairer et al., 2006  ###reference_b19###), to analyze their properties.\nIn the remainder of the paper we will recall some theory from backward error analysis and geometric numerical integration of Hamiltonian vector fields. We then outline a framework for constructing SympNets, and then suggest a few models that fit within it. We then present numerical experiments including Hamiltonian system identification and give concluding remarks in the final section."

This framework relies on the fact that we can find a set of basis Hamiltonians such that the layers  can be computed, which is the subject of the next section. For now, we will assume that this is possible. Framing a SympNet is such a way allows us to leverage a number of concepts from dynamical systems theory and numerical analysis. This has been repeatedly demonstrated in several studies to be a powerful tool when analyzing properties of neural networks, e.g., (Haber and Ruthotto, 2017  ###reference_b18###; Chang et al., 2019  ###reference_b8###; Sherry et al., 2024  ###reference_b42###; Celledoni et al., 2023b  ###reference_b7###; Chen et al., 2018  ###reference_b10###; Galimberti et al., 2023  ###reference_b17###; Celledoni et al., 2023a  ###reference_b6###). We will now outline some properties of such SympNets. The first and most important one is the following.\nIf  is dense in , then Theorem 1  ###reference_orem1### guarantees that , according to Definition 3  ###reference_inition3###, is dense in Hamiltonian diffeomorphisms.\nAnother advantage is due to the following obvious lemma.\nLet  be dense in .

Furthermore, we can then use inverse BEA to identify the true Hamiltonian, which we will discuss in detail in Section 5  ###reference_###.\nNext, we observe that SympNets of this form are simply splitting methods of Hamiltonian flows, which form a group under composition (Polterovich, 2012  ###reference_b39###). That is, if  and  are the flows of the Hamiltonian vector fields  and , then  is a Hamiltonian flow of the Hamiltonian vector field , where .\nSympNets according to Definition 3  ###reference_inition3### are Hamiltonian flows and form a group under composition. That is, if  and  are SympNets, then  is also a SympNet and hence a Hamiltonian flow. Furthermore, the inverse is the map with negative timestep and their layers reversed\nFurthermore, we have the following obvious property, which is true of all symplectic flows.\nSympNets according to Definition 3  ###reference_inition3### preserve volume in phase space, meaning\nThis has been suggested to yield more stability in training.\nAnother property of SympNets is that they circumvent the vanishing gradient problem. This is a well-known phenomenon in deep learning that places limitations on the depth of neural networks. This arises during a gradient descent step of the form\nwhere  is the loss function. The idea is to find stationary points of the loss function by iteratively updating the parameters  in the direction of the negative gradient. Denote by  the output of the th layer of a -layer SympNet . Then we can express the gradient for the th parameter of layer  by\nThe matrix  which is referred to as the backward stability matrix is the product of the Jacobians of the layers with respect to their inputs. As the number of layers increases and the Jacobians become small then  vanishes and  tends to zero despite not reaching a minimum. This is known as the vanishing gradient problem. The opposite case, where  becomes very large, is known as the exploding gradient problem. As shown in (Galimberti et al., 2023  ###reference_b17###, Theorem 3), when the layers are symplectic, one can bound the norms of , for , from below.\n(Galimberti et al., 2023  ###reference_b17###)\nLet  be any sub-multiplicative matrix norm, then\nfor .\nProof \nUsing the fact that  are symplectic matrices, we have that\nfor , which implies the result.\n  \n\nWe therefore have the following.\nSympNets according to Definition 3  ###reference_inition3### do not suffer from the vanishing gradient problem.\nSympNets could suffer from exploding gradients, however this can also be circumvented by adding a L2 regularization term to the loss function, also explored in Galimberti et al. (2023  ###reference_b17###). Due to Lemma 1  ###reference_ma1### , there exists solutions to the basis Hamiltonians that are small, meaning that an L2 regularization term makes sense and does not introduce an erroneous inductive bias. Furthermore, in Section 4.5  ###reference_### we verify that the proposed SympNets usually learn small values for the parameters.\nSo, given a set of basis Hamiltonians  that are dense on compact sets in  then the composition method  will possess the above properties. However, we still need to compute the flows , also called layers. We will now explain how this can be achieved."

The main observation here is that the SympNets that use separable flows, namely the LA, G and H-SympNets require learning relatively large values. Whereas the P and R-SympNets learn smaller value.

+            "text": "One of the common observations throughout the experiments is that increasing the number of parameters, e.g., by increasing the layers and/or widths, does not necessarily increase the accuracy of the models. This can be seen by the fact that the models do not usually become more accurate as the training time increases. This is somewhat at odds with the fact that the models are all universal approximators for Hamiltonian flows. However, this suggests that there might be challenges with the training, and more specialized methods could more effectively find the optimal hyperparameters for the problem. We have suggested a possible explanation for this, namely the fact that models might require learning large parameter values. Hence, it is possible that one simply needs to train the models for a lot longer. A notable exception to this are the P-SympNets that often increases in accuracy with the training cost and number of parameters. This could be due to reasons explained in the following paragraph.\nIn general, the P-SympNets consistently outperform the other models in terms of cost, accuracy, and generalizability. There are a number of potential reasons that could explain this. One, due to the fact that P-SympNets can represent linear Hamiltonian flows exactly, data sets that are dominated by linear dynamics and have perturbative or smaller nonlinear terms could be learned more effectively. Two, all the Hamiltonians used in the training data are polynomial or analytic functions, which are in a sense the \u201csmoothest\u201d class of functions one could conceive. So approximating the inverse modified Hamiltonian with a polynomial is in a sense introducing a \u201csmoothness\u201d inductive bias into the model that evidently works very well. It would be interesting to see whether P-SympNets perform equally well on Hamiltonians that are not analytic. However, in Lin et al. (2017  ###reference_b30###), the argument is made that many physical systems arise from low order polynomials, meaning that it could be wise to inform our neural models of this fact. It would therefore make sense to use P-SympNets in this context.\nWhen it comes to distinguishing between the G, H and R-SympNets, it is difficult to single out any general trends across all experiments. For separable systems (e.g., the H\u00e9non-Heiles and Fermi-Pasta-Ulam systems) these methods are similar in terms training costs and accuracy. This could mean that models with a separable inverse modified Hamiltonian (G, LA and H-SympNets) are a sensible choice when the dynamics is generated by a separable Hamiltonian process. However, it can be seen that the GR-SympNet performs very well for the double pendulum experiment, which is likely due to its increased expressiveness compared to the G-SympNet and the fact that the true Hamiltonian is non-separable. However, this performance is nearly matched by the H-SympNet in many cases.\nA logical question to ask is how the models handle noise in the data. We remark that all the SympNets presented in this paper are amenable to methods such as initial state optimization (Chen et al., 2019  ###reference_b12###) or mean inverse integration (Noren et al., 2023  ###reference_b35###), which have been shown to effectively reduce the effect of noise in the training process. We haven\u2019t considered noisy data sets in this paper as we believe it doesn\u2019t make sense to consider noisy data sets without adapting our methods to the above methods. However, it is a natural next step to adapt our methods to handle realistic systems, including dissipation and noise.\nOne theoretical question that remains open is whether the generating Hamiltonian set for GR-SympNets (i.e.,  from Definition 7  ###reference_inition7###) is dense in compact subsets of . This would explain the fact that they learn reasonably small parameters as seen in Section 4.5  ###reference_### as well as explain their efficiency in approximating Hamiltonian flows and provide an alternate proof of their universality according to Theorem 1  ###reference_orem1###."

+    "title": "TDNetGen: Empowering Complex Network Resilience Prediction with Generative Augmentation of Topology and Dynamics",
+    "abstract": "Predicting the resilience of complex networks, which represents the ability to retain fundamental functionality amidst external perturbations or internal failures, plays a critical role in understanding and improving real-world complex systems. Traditional theoretical approaches grounded in nonlinear dynamical systems rely on prior knowledge of network dynamics. On the other hand, data-driven approaches frequently encounter the challenge of insufficient labeled data, a predicament commonly observed in real-world scenarios. In this paper, we introduce a novel resilience prediction framework for complex networks, designed to tackle this issue through generative data augmentation of network topology and dynamics. The core idea is the strategic utilization of the inherent joint distribution present in unlabeled network data, facilitating the learning process of the resilience predictor by illuminating the relationship between network topology and dynamics.\nExperiment results on three network datasets demonstrate that our proposed framework TDNetGen can achieve high prediction accuracy up to 85%-95%. Furthermore, the framework still demonstrates a pronounced augmentation capability in extreme low-data regimes, thereby underscoring its utility and robustness in enhancing the prediction of network resilience. We have open-sourced our code in the following link, https://github.com/tsinghua-fib-lab/TDNetGen.",

+            "text": "Real-world complex systems across various domains, such as ecological (Holland et al., 2002  ###reference_b20###), gene regulatory (Alon, 2019  ###reference_b4###), and neurological networks (Wilson and Cowan, 1972  ###reference_b52###, 1973  ###reference_b53###), are often described as complex networks composed of interconnected nodes with weighted links. A fundamental characteristic of these systems is their resilience (May, 1977  ###reference_b39###; Gao et al., 2016  ###reference_b18###), that is, the ability to maintain functionality in the face of disruptions. From the perspective of dynamical systems, nodal state evolution of complex networks is driven by underlying nonlinear dynamics. Specifically, with the functionality of each node represented by its state value, a resilient network can recover from disruptions (on its nodes) and dynamically evolve into a stable phase where all nodes operate at a high level of activity (see Figure 1  ###reference_###). Understanding and predicting this critical property of resilience in complex networks not only enhances our ability to analyze and intervene in natural and social systems (Gao et al., 2016  ###reference_b18###; Zhang et al., 2022  ###reference_b60###; Sanhedrai et al., 2022  ###reference_b43###; Su et al., 2024  ###reference_b45###) but also offers valuable insights for the design of engineered infrastructures (Xu et al., 2019  ###reference_b54###).\n###figure_1### To predict network resilience, theories grounded in nonlinear dynamical systems have been developed (Gao et al., 2016  ###reference_b18###; Laurence et al., 2019  ###reference_b31###; Jiang et al., 2020  ###reference_b27###; Zhang et al., 2020  ###reference_b61###).\nThese frameworks strive to separate the influences of network structure and dynamics to derive analytical solutions for complex, high-dimensional systems (Ollerton et al., 2007  ###reference_b42###; Balaji et al., 2006  ###reference_b7###; Gama-Castro et al., 2008  ###reference_b17###). However, theoretical approaches often presuppose a detailed understanding of network evolution dynamics, which is usually not available in practical scenarios.\nIn contrast, data-driven methods are capable of extracting both structural and dynamic information about networks directly from observational data (Ding et al., 2024  ###reference_b13###; Wang et al., 2023  ###reference_b51###; Mao et al., 2023  ###reference_b36###, 2024  ###reference_b37###; Li et al., 2024  ###reference_b33###), allowing for resilience predictions without the need for predefined knowledge. From this perspective, the task of predicting network resilience can be reinterpreted as a graph classification problem based on data of network structure and dynamics using machine learning techniques.\nNonetheless, the crucial role of resilience in system functionality means that collecting extensive labeled datasets from real-world complex networks is both expensive and impractical. As a result, the majority of network observations remain unlabeled, possessing information on network topology and nodal state trajectories but lacking resilience labels.\nIn this paper, we focus on addressing the problem of predicting network resilience amidst a scarcity of labeled data, identifying two primary obstacles:\nFirstly, designing models for resilience prediction is inherently complex due to the intricate interplay between network structure and dynamics. A network is considered resilient if it can consistently return to a state where all nodes are active following a prolonged period of self-evolution and neighborly interactions. However, while topological data is readily available, constructing a practical model requires the capability to make accurate predictions based on partial evolution trajectories collected from a short time window.\nSecondly, enhancing prediction accuracy in the face of scarce labels involves leveraging the intrinsic information embedded in unlabeled data regarding network structure and dynamics. Existing methodologies mainly include pseudo-labeling (Lee et al., 2013  ###reference_b32###; Tagasovska and Lopez-Paz, 2019  ###reference_b46###; Amini et al., 2020  ###reference_b5###), exemplified by self-training (Iscen et al., 2019  ###reference_b26###), and self-supervised learning (Hu et al., 2019  ###reference_b22###; Veli\u010dkovi\u0107 et al., 2019  ###reference_b49###; Xu et al., 2021  ###reference_b55###; Kim et al., 2022  ###reference_b29###). Pseudo-labeling tends to underperform with high model uncertainty, and self-supervised learning often overlooks the critical interplay between structure and dynamics, treating state evolution trajectories merely as node attributes. The graph data augmentation method (Han et al., 2022  ###reference_b19###) emerges as a leading technique by utilizing unlabeled data distribution to generate diverse augmented samples for improved training. However, the challenge of comprehensively characterizing the distribution of both topology and dynamics in unlabeled data has yet to be tackled, especially with limited observations, such as a few labeled networks and incomplete evolution trajectories.\nTo fully resolve these challenges, we introduce a novel resilience prediction framework called TDNetGen, which utilizes generative augmentation of network topology and dynamics. The core of TDNetGen is a neural network-based predictor that integrates a graph convolutional network-based topology encoder together with a transformer-based trajectory encoder, capturing the complex relationship between network structure and dynamics. This predictor is further refined through training on an augmented dataset comprising resilient and non-resilient samples, i.e., networks with topology information and evolution trajectories.\nTDNetGen leverages a generative data augmentation approach by 1) capturing the underlying joint distribution of topology and dynamics in unlabeled data, and 2) obtaining the corresponding conditional distribution for each class label through a classifier-guided approach (Dhariwal and Nichol, 2021  ###reference_b12###).\nTo facilitate effective generative learning in the vast joint space of topology and dynamics, we decouple the generation process into topology generation using a topology denoising diffusion module and dynamics simulation with a dynamics learning module.\nTo ensure robust learning with limited observations, we incorporate a fine-tuning step for the resilience predictor on generated trajectories, thereby improving its generalization ability on unseen data.\nTo summarize, our main contributions are as follows.\nWe tackle the critical problem of predicting complex network resilience under label sparsity issue and provide a novel perspective of improving by data augmentation.\nWe design a generative augmentation framework that benefits resilience predictor learning of interplay between network topology and dynamics by exploiting the underlying joint distribution in unlabeled data.\nEmpirical results on three network datasets demonstrate the superiority of our TDNetGen over state-of-the-art baselines in terms of increasing network resilience prediction accuracy up to 85%-95%. Moreover, aided by a generative learning capability of both topology and dynamics, TDNetGen can provide robust augmentation in low-data regimes, maintaining  of performance even when dynamic information cannot be observed in unlabeled data.\n###figure_2###"

However, it is important to note that the simulated nodal states are confined to the initial temporal period, corresponding to the maximal duration present within the training dataset, and compelling the dynamics learning module to simulate time steps beyond its training scope yields results of questionable reliability. Consequently, the principal challenge arises from the inability to ascertain the steady-state conditions of the generated networks. This limitation obstructs the direct acquisition of resilience labels, presenting a significant impediment to the data augmentation.\nTo overcome this problem, we advocate for the strategy of guiding the topology diffusion module, enabling it to generate networks with predefined resilience characteristics.

For example, on mutualistic dataset, the F1-score of the resilience predictor previously trained on 100 labeled data increases from 0.838 to 0.929 (+10.86%), and its ACC increases from 0.848 to 0.934 (+10.14%) after training on the augmented data. Moreover, our framework also improves the best baseline among all self-training, self-supervised learning, and GDA methods w.r.t. F1-score by , , , and w.r.t. ACC by , , , on mutualistic, regulatory and neuronal dataset, respectively. All these results demonstrate the outstanding performance of our proposed framework. We find that the best baseline methods on three datasets belong to the category of graph data augmentation. Compared with TRY and G-mixup, we achieve to jointly model network topology and dynamics in a fine-grained manner.\nRobustness performance without nodal state trajectories of unlabeled data.\nIn certain contexts, the requirement to obtain the nodal states, even only for an initial phase of evolution, still proves to be difficult or costly. Consequently, we analyze scenarios where the nodal state trajectories of unlabeled data are inaccessible and we can only train the dynamics learning module on those of limited labeled data  in Equ. (11  ###reference_###). Results in Table 2  ###reference_### demonstrate that our framework is capable of sustaining commendable performance even under such constrained conditions and surpassing the best baseline in most scenarios. It underscores the versatility of our framework and its potential effectiveness under more limited data availability of the real world scenarios.\nSelf-training cannot universally guarantee a positive impact on model performance. The results demonstrate that self-training methods have a relatively small positive effect on predictive performance among all three datasets compared to our framework TDNetGen. For example, on regulatory datasets, the F1-score of the resilience predictor increases 0.051, and its ACC increases 0.079 compared to the vanilla model. This is because the labels assigned to the augmented data in the self-training process originate from the model itself with sub-optimal predictive performance. This approach inherently carries the risk of generating labels that are incongruent with the ground truth and partially introduce contradictory information into the training dataset. The presence of such inaccurately labeled data can confound the learning algorithm, leading to a deterioration in the model\u2019s capacity to make accurate predictions.\nExtracting knowledge from unlabeled data via hand-crafted self-supervised tasks offers marginal benefits to the resilience prediction.\nWe also find that models trained on self-supervised tasks can only extract limited knowledge from unlabeled data to benefit the resilience prediction task. From the results, the improvement to vanilla model from competitive self-supervised learning methods (ContextPred (Hu et al., 2019  ###reference_b22###) and Infomax (Veli\u010dkovi\u0107 et al., 2019  ###reference_b49###)) is still relatively marginal compared to our framework (+, + and +, on mutualistic, regulatory, neuronal dataset, respectively).\nThe primary reason for the observed discrepancy lies in the substantial divergence between conventional hand-crafted tasks, which only focus on the modeling of topological structures. In the resilience prediction task, however, we also need to consider nodal state dynamics of networks."

The results reveal that the F1-score of the ablation model significantly declines\n, , and \ncompared to the full model design,\nwhich underscores the importance of guided generation.\nEffectiveness of resilience predictor fine-tuning on dynamics learning module-produced trajectories.\nIn this experiment, we remove the fine-tuning procedure of the resilience predictor on dynamics learning module-produced trajectories, instead utilizing the one trained with ground-truth trajectories.\nThe results illustrate that fine-tuning could significantly enhance its guidance capabilities to generate higher-quality data, ultimately empowering the resilience predictor to be re-trained on it.\nArchitecture analysis.\nWe compare our diffusion-based topology generation module with generative adversarial network (GAN) module. Specifically, we replace topology generation module as a GAN-based module proposed in (Martinkus et al., 2022  ###reference_b38###).\nWe use the topologies of unlabeled data to train the GAN model, and sample new topologies from it. The nodal state trajectories and the resilience label are produced by our dynamics learning module and the resilience predictor, respectively.\nExperiments demonstrate that our original design of diffusion models exhibit superior generative performance compared to GANs,\nwhich underscores the efficacy of diffusion models in capturing the underlying topology data distribution, thereby facilitating more accurate and reliable topology generation."

From the results, we find that the predictive performance of the vanilla model is generally proportional to the number of labeled data used for training. TDNetGen is robust to the limitation of labeled data, which can still generate reasonable samples to benefit the predictive performance of the vanilla model. These findings underscore the versatility and potential of our proposed framework, particularly in scenarios characterized by a scarcity of labeled data, which constitutes a small portion of the available dataset.\nShorter nodal state trajectories.\nWe also investigate the performance of the vanilla model and TDNetGen while using shorter nodal state trajectories, which contain  time steps. We discover that the performance of the vanilla model improves with the increase in trajectory length since the model can extract more knowledge about nodal state dynamics from data to make more accurate resilience predictions. In this scenario, TDNetGen can also help to augment the model\u2019s performance, which suggests that even in situations where nodal state trajectories are costly to acquire, our framework remains applicable and effective for data augmentation purposes of simultaneously generating plausible topologies and nodal state trajectories of complex networks.\n###figure_7### ###figure_8### ###figure_9### ###figure_10###"

Once manufactured, their dispersive qualities remain invariant in time and space, limiting their practical use. Actively tuned arrangements have received growing interest to address this issue. Here, we introduce a new class of active metamaterial made from dual-state unit cells, either vibration sources when powered or passive resonators when left disconnected. They possess self-tuning capabilities, enabling deep subwavelength band gaps to automatically match the carrier signal of powered cells, typically around . Swift electronic commutations between both states establish the basis for real-time reconfiguration of waveguides and shaping of vibration patterns.

They are engineered structures, often lattice of subwavelength resonators [3  ###reference_b3###, 4  ###reference_b4###]. Their collective action endows the bulk material with unusual effective properties such as a negative mass density and/or a negative modulus [5  ###reference_b5###, 6  ###reference_b6###, 7  ###reference_b7###, 8  ###reference_b8###]. These properties, typically not found in nature, unlock novel wave phenomena [9  ###reference_b9###, 10  ###reference_b10###, 11  ###reference_b11###], including the ability to stop wave propagation in specific frequency ranges called band gaps. Unlike those derived from Bragg scattering [12  ###reference_b12###], these band gaps stem from the hybridization of local resonances with free-space dispersion. Crucially, they are independent of wavelength, allowing for compact and practical metamaterial designs.\nFollowing their success in optics [13  ###reference_b13###] and acoustics [14  ###reference_b14###], metamaterials have sparked interest in haptics [15  ###reference_b15###]. Unlike conventional control and geometric methods [16  ###reference_b16###, 17  ###reference_b17###, 18  ###reference_b18###], they are robust, versatile, and highly effective at confining elastic waves for the rendering of precise, vibration-based tactile feedback [19  ###reference_b19###]. However, once manufactured, these passive structures possess fixed dispersive properties and spatial arrangements that limit their use, whether in haptics or other fields. Additionally, their operating frequency is bounded by the Kramers-Kronig relations [20  ###reference_b20###].\nTo address these issues, researchers have introduced active unit cells [21  ###reference_b21###]. They support various functions including loss compensation in non-Hermitian metamaterials [22  ###reference_b22###], reconfiguration of waveguides [23  ###reference_b23###], and adjustment of band gaps [24  ###reference_b24###]. Piezoelectric transducers are widely used for activating these cells, mainly due to their adjustable stiffness through shunting. They were leveraged to alter resonances by making variable junctions [25  ###reference_b25###, 26  ###reference_b26###], establish tunable acoustic filters [27  ###reference_b27###], trap waves spatially following a specified spectrum [28  ###reference_b28###], and reconfigure acoustic lenses in real time [29  ###reference_b29###]. Such dynamic systems are best suited for low-amplitude, high-frequency applications, typically in the  to  ranges. Electromagnetic actuation offers complementary capabilities. It often involves moving an extraneous permanent magnet to remotely toggle the effective modulus between positive and negative [30  ###reference_b30###], or selectively activate resonators for outlining waveguides [31  ###reference_b31###, 32  ###reference_b32###], albeit with a  latency per cell. Alternatively, electromagnetic actuation can be distributed within each unit cell by embedding energized coils. They can set bistable or tristable resonators in distinct states, thus controlling band gaps [33  ###reference_b33###, 34  ###reference_b34###], phase changes [35  ###reference_b35###], and polarization [36  ###reference_b36###]. This approach also achieves low-frequency band gaps under  via continuously variable stiffness adjustments [37  ###reference_b37###].\nBy enabling real-time reconfiguration of waveguides, active metamaterials could be the key to developing a multi-touch, programmable vibration-based display, a major goal of haptic research [38  ###reference_b38###]. Human touch is exquisitely sensitive to rapid transients and low-frequency vibrations up to about  [39  ###reference_b39###, 40  ###reference_b40###], requiring deep subwavelength unit cells the size of a finger pad. However, current active unit cells do not meet haptic requirements. Electromagnetic-based cells are not configured for real-time response, while piezoelectric-based cells operate at excessively high frequencies. Additionally, existing active unit cells can only control a single global vibration source, such as ambient noise, rather than multiple stimuli.\n###figure_1### To overcome these limitations, we introduce a novel type of active acoustic metamaterial. It consists of dual-state unit cells made from off-the-shelf electromagnetic linear resonant actuators (LRAs), commonly found in smartphones and game controllers. Both theoretical and experimental results show that a 1D array of LRAs induces a self-tuned, deep sub-wavelength band gap, within touch-relevant frequencies. We report a method to tailor acceleration fields in real-time, enabling the spatial encoding of binary words and time-varying patterns. We demonstrate its relevance for tactile perception. This work opens up new avenues for responsive multi-touch haptic displays, mechanical computing, and overall democratizes active metamaterials through a low-cost, non-expert approach."

This resonant actuator, illustrated in Fig. 1  ###reference_###.D, consists of a mass attached to a spiral flexure spring, which restricted oscillations to the -axis. Requisite active elements are already embedded inside typical LRAs, including a neodymium magnet attached to the moving mass and a coil fixed to the casing. When an alternating current is applied to the coil, the Lorentz force causes the mass to oscillate, generating transverse waves in the base that produce vivid vibrotactile sensations. This was termed the \u201cactuator state\u201d\u200b, as schematized in Fig. 1  ###reference_###.B. On the other hand, if the coil is left disconnected, i.e. in an open circuit, no current can establish and the unit cell remains a passive resonator. This will further be referred to as the \u201cresonator state\u201d\u200b. The possibility of a third state that would allow unimpeded vibration propagation was also investigated. This involved shorting the coil to induce eddy current damping in an attempt to nullify resonances. However, it proved insufficient, achieving only a 10.5% reduction in quality factor (see Supplementary Fig. 1).\nThe dynamic response of a unit cell, central to the formation of a band gap, was assessed experimentally (see Methods). As shown in Fig. 1  ###reference_###.E, the results are in excellent agreement with a second-order linear time-invariant model (\u200b, see Supplementary Information). The moving mass, , combined with a compliant spring, \u200b, gave a resonance frequency . The DC gain, , was evaluated at \u200b. The high quality factor, , achieved through frictionless guiding and minimal damping, is ideal for making a resonant acoustic metamaterial. For simplicity, the close-packed square lattice was reduced to a linear arrangement, as illustrated in Fig. 1  ###reference_###.C. As depicted in Fig. 1  ###reference_###.F, a prototype was manufactured with an array of 11 LRAs. They were glued under an elongated printed circuit board (PCB) substrate for seamless integration of driving electronics and sensors (see Methods)."

Instead, using an array of low-loss resonators provides a closed-form solution, enabling analytical optimization and a deeper understanding of the underlying physics. To unveil the band structure, the PCB substrate was modeled as an infinite series of Timoshenko-Ehrenfest beams of length , as shown in Fig. 2  ###reference_###.A. Each junction was described by an effective stiffness, \u200b, representing the reaction force of an LRA (see Supplementary Fig. 2.A). By virtue of its periodic symmetry, the problem was reduced to that of a single segment endowed with both continuity and Floquet-Bloch boundary conditions (see Supplementary Information). It yielded the theoretical dispersion diagrams in Fig. 2  ###reference_###.B, revealing a complete band gap wherein only an evanescent field established. The band gap width, , followed an inverse power-law relationship with PCB thickness, , demonstrating excellent agreement (, see Supplementary Fig. 2.B). In extremely thin substrates, the upper bound of the band gap tends to infinity. However, this would not occur in practical implementations due to high-order modes, unaccounted for in this model, which would otherwise alter the band structure. A  thickness, prevalent for PCBs, was chosen to induce a theoretical band gap from  to , aligning with the range of peak vibrotactile sensitivity mediated by Pacinian corpuscles [41  ###reference_b41###, 40  ###reference_b40###], as shown in Fig. 2  ###reference_###.C.\nThese attenuation qualities were verified experimentally by measuring the transmission coefficient, , between two distinct unit cells (see Methods). Given the symmetry of our prototype, it was computed with respect to the central unit cell, indexed , such as , where  is the Fourier transform of the transverse acceleration of the th\u200b unit cell, with . Left-hand side transmission coefficients, for , are presented in Fig. 2  ###reference_###.D. Right-hand side results are analogous despite minor discrepancies (see Supplementary Fig. 3.A).\nA band gap ranging from  to  was observed. Theory overestimated its boundaries by 37.4% and 94.4%, respectively. This may be attributed to several factors including part-to-part variations among LRA batches, mechanical coupling between the steel casings of adjacent LRAs, and overlooked torsional modes that might have further reduced the band gap. A maximum attenuation of  at  was recorded five unit cells away from the vibration source. As shown in Fig. 2  ###reference_###.D, the peaks, labeled , are shifted towards higher frequencies as more unit cells are involved. This blueshift is linearly correlated to the transmission coefficient (Pearson correlation coefficient , ), as shown in Fig. 2  ###reference_###.F. In fact, the attenuation gradually established with the number of unit cells recruited. As it better approximates the theoretical infinite model, the attenuation converges towards a maxima for . A convergence error of only 8% was measured at , five unit cells away from the source. Within the band gap, Floquet-Bloch\u2019s theorem predicts that vibration amplitude decays exponentially with the number of unit cells (see Supplementary Information). It followed piecewise linear functions instead (), as shown in Fig. 2  ###reference_###.E. This might be attributed to the small number of unit cells considered. Nonetheless, assuming a smooth decay, the transmission coefficient would still approach zero asymptotically, in line with Floquet-Bloch\u2019s predictions. These linear fits failed to intercept the unity transmission coefficient, indicating nonlinearity near the vibration source.\nOur acoustic metamaterial was assumed to be primarily subjected to Lamb waves with an asymmetric A0 mode. Their wavelength,  at , was estimated using finite element analysis (see Supplementary Information). In turn, the dimensionless ratio, , indicates exceptional subwavelength capabilities. This metamaterial can hinder the propagation of elastic waves with wavelengths 22 times larger than a single unit cell. This is a testament to the effectiveness of leveraging prior industrial efforts directed towards the optimization of resonators for mobile applications."

To mitigate these effects, a common strategy in numerical simulations is to terminate edges with perfectly matched layers that provide near-zero reflection [42  ###reference_b42###, 43  ###reference_b43###]. However, this solution is not easily implemented in practice. As an alternative, previous transmission measurements were replicated at varying levels of boundary impedance. This was achieved by suspending the metamaterial on flexures, whose stiffness was adjusted via a tensioning motion  (see Methods, Supplementary Fig. 4, and Movie 1).\nVariations in transmission coefficients are presented in Fig. 2  ###reference_###.G, at five levels of boundary impedance, each obtained by  increments from the reference signal taken at . Results are given for  (see Supplementary Fig. 3.B for remaining values of ). The band gap is the only frequency range that remained mostly unaffected by changes in boundary conditions. As shown in Fig. 2  ###reference_###.H, the RMSE with respect to the reference, , is one to two orders of magnitude lower within the band gap than outside of it. Furthermore, the RMSE outside the band gap increases with the distance from the vibration source, showing significant edge effects otherwise barely seen within the band gap. This provides further evidences that the extraordinary attenuation qualities are intrinsic to the resonant acoustic metamaterial rather than an artifact of suitably designed boundaries."

In turn, the carrier frequency naturally falls within the band gap of a metamaterial made from remaining LRAs in a resonator state. It is, in that sense, self-tuned. By strategically arranging unit cells in both states, vibrations can be confined in localized areas. However, sufficient spacing must be introduced between activated unit cells to minimize crosstalk.\nThis was investigated by driving two unit cells with a sinusoidal carrier and increasing their separation, , in  increments up to , as illustrated in Fig. 3  ###reference_###.B. The RMS acceleration profiles along the metamaterial were interpolated by cubic splines, as shown in Fig. 3  ###reference_###.A. Within the band gap, adjacent sources induced a unique vibration spot. To create distinct spots, they had to be separated by at least . This is evident from the inflection point in the acceleration gradient, as shown in Fig. 3  ###reference_###.D. To achieve the sharpest vibration spots, characterized by the highest gradient,  should be maximized. In practise, this was limited by wave reflections when LRAs were activated close to the extremities. This effect was particularly pronounced beyond the band gap, at , where destructive interference led to a minimal acceleration, even near vibration sources.\nFurther insights into the attenuation qualities were gained by analyzing a larger number of unit cells than in the previous experiment. This corroborates the exponential decay of evanescent waves predicted by Floquet-Bloch theory (), as depicted in Fig. 3  ###reference_###.C."

The falling edge was followed by an exponential decay with a time constant , slightly overestimated by 28.4% by the second-order model, . The rising edge established even faster due to the forced response. These results support the use of electromagnetic actuation in combination with MOSFET-based commutation to enable swift reconfiguration. In fact, the limiting factor is the lack of damping, rather than electronics. However, increasing damping could inhibit the resonant band gap.\nThe ability to rapidly shape vibration patterns holds potential for information storage and transmission, which can be quantified by the bandwidth. It was explored by encoding binary words spatially in the wave field. Limiting them to 3 bits, , ensured they were sufficiently spaced apart with . Although slightly less than the previously defined threshold, it effectively reduced crosstalk between each bit while maintaining compactness. The steady-state RMS acceleration for 3-bit binary numbers counted from zero to seven at  intervals is given in Fig. 3  ###reference_###.G (see Supplementary Movie 2). These patterns can be simply deciphered by thresholding the histogram of RMS acceleration. For each carrier, an optimal threshold can be found numerically, as shown in Fig. 3  ###reference_###.H. The decoding success rates are given in Fig. 3  ###reference_###.I. Outside the band gap, it remained close to chance level, independent of the delay, as uncontrolled propagation blurred the binary words. Nonetheless, an exact retrieval is possible for carriers within the band gap, provided that a minimum delay of  is respected between each word. This confirms previous observations on the time required to settle a logic state. Despite using electromagnetic unit cells, our metamaterial achieved a reconfiguration time comparable to that of piezoelectric metalenses () [29  ###reference_b29###].

A two-way repeated measures ANOVA revealed significant effects of both the vibration pattern () and the carrier frequency (). This strongly indicates that the perception of local stimuli was mediated by the band gap. These findings are consistent with the acceleration fields depicted in Fig. 3  ###reference_###.G. The interaction term between pattern and frequency significantly impacted the success rate (). To further explore this effect, the data was segregated based on the number of simultaneously activated LRAs and a two-way repeated measures ANOVA was conducted. A post-hoc Tukey-Kramer test revealed that an activation of one or two LRAs yielded similar success rates, both in () and out () of the band gap, as shown in Fig. 4  ###reference_###.B. Despite the lack of statistical significance ( and ), a notable contrast was observed when all three LRAs were activated. In that case, the band gap had a negligible effect on perception as participants seemed to confuse multiple vibration points with vibration spread. The increased variance in success rate illustrates this confusion. The mislocalization of tactile stimuli may have also been caused by a funneling illusion, as described by von B\u00e9k\u00e9sy [44  ###reference_b44###, 45  ###reference_b45###].\nOverall, participants could accurately perceive tactile messages spatially encoded on three bits with a success rate of .

It minimized spectral leakage, limiting high-frequency artifacts that might have otherwise extended beyond the band gap (see Supplementary Fig. 5).

To reveal regions with significant differences in vibration levels, they were binarized using Otsu\u2019s thresholding method. Only the central panel, for carrier frequencies inside the band gap, features a unique vibration spot, shown in white, centered around the reference path. Such single anti-node moving both in time and space demonstrates the effectiveness of our approach. This is further supported by the global Moran\u2019s index, which measures spatial autocorrelation. Clustering, typical of an isolated vibration spot, indeed led to the highest autocorrelation values, as evident in Fig. 5  ###reference_###.F. The reference path was traveled at velocities, , up to  (see Supplementary Movie 3). As shown in Fig. 5  ###reference_###.C for a  carrier, successful path following was achieved regardless of velocity (). This capacity extends to sinusoidal paths, as shown in Fig. 5  ###reference_###.E (see Supplementary Movie 4). Therefore, the proposed metamaterial enables continuous steering of low-frequency vibration spots in both time and space. This holds great promise for rendering compelling sensations of tactual apparent motion [46  ###reference_b46###]."

It consists of a series of dual-state unit cells, either resonators when left disconnected or vibration sources when powered. Conveniently, these unit cells can be made from off-the-shelf LRAs, commonly found in smartphones. They create a self-tuned metamaterial with a band gap that intrinsically includes the optimal actuation carrier frequency. A major strength of this approach is its potential to create acoustic metamaterials with minimal knowledge, serving as a turnkey solution for haptic designers.\nComprehensive theoretical and experimental investigation of a 1D prototype unveiled a band gap ranging from about  to , with a maximum attenuation of  at , after five unit cells. This effect was conclusively attributed to local resonances, rather than boundary conditions. A bespoke controller supports real-time reconfiguration of the metamaterial in less than . This enables dynamic shaping of vibration patterns with a bandwidth of about \u200b. In addition, these unit cells exhibit deep subwavelength characteristics by stopping the propagation of waves with wavelengths 22 times their size. This paves the way for materials that mediate vibrotactile feedback in a compact form factor.\nA perceptual experiment demonstrated how human subjects were successfully able to retrieve 3-bit messages ingrained spatially on a -long prototype. Its ability to steer a vibration spot along a smooth spatiotemporal path also offers a promising solution for creating compelling illusions of apparent motions. In turn, this work has direct translational applications as a live communication device for the visually impaired as it already follows the Perkins Brailler layout. Beyond manifest tactile applications in multi-touch refreshable displays, storing bits of elastic energy spatially with a dynamic allocation might be an interesting use case for purely analog computing solutions."

They were glued on an elongated PCB with a thin layer of cyanoacrylate adhesive (454, Loctite), resulting in a rigid bond that effectively transmitted vibrations. Both extremities of the metamaterial were suspended by flexures cut in a -thick polyimide film (Kapton, DuPont). A pop-up structure was designed within this rigid-flex assembly to provide adjustable tensioning of the flexures via a linear motion  (see Supplementary Fig. 4). Manual setting is demonstrated in Supplementary Movie 1. This allowed the study of dispersive effects due to changes in boundary stiffness, which increased monotonically with flexure tension. These flexures also created efficient routing paths for electrical signals ( traces), avoiding undesired stiffness from cables.

+    "abstract": "Whereas Wi-Fi communications have been exploited for sensing purpose for over a decade, the bistatic or multistatic nature of Wi-Fi still poses multiple challenges, hampering real-life deployment of integrated sensing and communication (ISAC) within Wi-Fi framework.\nIn this paper, we aim to re-design Wi-Fi so that monostatic sensing (mimicking radar) can be achieved over the multistatic communication infrastructure.\nSpecifically, we propose, design, and implement ISAC-Fi as an ISAC-ready Wi-Fi prototype. We first present a novel self-interference cancellation scheme, in order to extract reflected (radio frequency) signals for sensing purpose in the face of transmissions.\nWe then subtly revise existing Wi-Fi framework so as to seamlessly operate monostatic sensing under Wi-Fi communication standard. Finally, we offer two ISAC-Fi designs: while a USRP-based one emulates a totally re-designed ISAC-Fi device, another plug-and-play design allows for backward compatibility by attaching an extra module to an arbitrary Wi-Fi device.\nWe perform extensive experiments to validate the efficacy of ISAC-Fi and also to demonstrate its superiority over existing Wi-Fi sensing proposals.",

+            "text": "Although the received signal strength carried by Wi-Fi signaling has been exploited by indoor localization for more than two decades [1  ###reference_b1###, 2  ###reference_b2###], the true Wi-Fi sensing (i.e., leveraging Wi-Fi communications) only started a decade ago thanks to the ability of extracting Channel State Information (CSI) from data packets [3  ###reference_b3###]. In particular, numerous applications of device-free Wi-Fi sensing have been proposed to utilize CSI, notably including localization/tracking [4  ###reference_b4###, 5  ###reference_b5###, 6  ###reference_b6###, 7  ###reference_b7###, 8  ###reference_b8###, 9  ###reference_b9###], activity/gesture recognition [10  ###reference_b10###, 11  ###reference_b11###, 12  ###reference_b12###, 13  ###reference_b13###, 14  ###reference_b14###, 15  ###reference_b15###, 16  ###reference_b16###], vital signs monitoring [17  ###reference_b17###, 18  ###reference_b18###], and object identification/imaging [19  ###reference_b19###, 20  ###reference_b20###, 21  ###reference_b21###]. Whereas these applications all bear a promising future, the bistatic\nnature of Wi-Fi infrastructure has largely hampered the deployment of real-life systems. Essentially, as a Wi-Fi communication session involves at least a pair of physically separated transmitter (Tx) and receiver (Rx), any sensing function piggybacking on this infrastructure is subject to the severe constraints imposed by the physical separation of Tx and Rx.\n###figure_1### ###figure_2### Among all constraints imposed by Wi-Fi\u2019s bistatic nature, we focus on three prominent ones illustrated in Fig. \u200b1a  ###reference_sf1###.111Device-based Wi-Fi sensing [22  ###reference_b22###, 23  ###reference_b23###, 24  ###reference_b24###] is a special type of bistatic sensing that aims to locate the Tx. Therefore, our ISAC revision to Wi-Fi is orthogonal to this type of sensing applications dedicated solely to localization. First of all, given the uncertainties such as the existence of carrier frequency offset and the lack of synchronization between Tx and Rx, even estimating the time-of-flight (ToF) of the line-of-sight (LoS) path between Tx and Rx entails a very cumbersome process [23  ###reference_b23###, 25  ###reference_b25###]. Unfortunately, the ToFs of the non-LoS (NLoS) paths, albeit essential to device-free sensing [7  ###reference_b7###, 9  ###reference_b9###]\nsimply cannot be estimated, hence forcing most of the proposals to be capable of sensing only a single target [11  ###reference_b11###, 13  ###reference_b13###, 14  ###reference_b14###, 16  ###reference_b16###].\nMoreover, whereas\nestimating angle-of-arrival (AoA)\nand motion become the centre of Wi-Fi sensing\ndue to the inability of obtaining ToF, the strong signal of the (useless) LoS path could easily overwhelm the essential NLoS paths. Consequently, existing proposals often have to rely on multiple Wi-Fi links (i.e., multistatic setting) [26  ###reference_b26###, 27  ###reference_b27###] and/or on motion effect as an extra hint [26  ###reference_b26###, 7  ###reference_b7###]. Finally, it is well known that the motion effect captured by a reflected RF signal represents the distance variation of a reflecting subject along a certain direction. According to Fig. \u200b1a  ###reference_sf1###, this direction happens to be the gradient of the Fresnel\nfield [18  ###reference_b18###], yet this gradient (along which the reflection path length changes) varies with the (unknown) location of the reflecting subject due to the bistatic nature of Wi-Fi, thus causing ambiguity in interpreting the motion sensing results.\nFortunately, all the aforementioned constraints can be lifted if the sensing mode can be converted to monostatic: the antenna of each Wi-Fi RF-chain, while transmitting data packets, also captures the reflected signals induced by the transmissions and certain reflecting subjects, as shown in Fig. 1b  ###reference_sf2###. Apparently, the ToFs of these reflection paths can be readily obtained as all uncertainties are removed thanks to the co-location of Tx and Rx. Moreover, the AoA and motion of a reflection path can be more accurately estimated without the LoS path interference, exploiting the MIMO (multiple-input and multiple-output) capability of a Wi-Fi device (i.e., its antenna array). Given both ToF and AoA, locating a reflecting subject can be achieved by only one device, yet one may further improve the sensing (for both localization and motion) accuracy by leveraging the interaction between a pair of communicating devices (a distributed MIMO setting).222It is worth noting that adding the monostatic mode to Wi-Fi sensing operations maximizes the utilization of radio frequency resources, as opposed to the serious wastes under the bistatic-only setting, because two devices in the latter setting obtain far less information than the same two in the former. Essentially, combining both monostatic and bistatic modes can only improve the sensing accuracy from the perspective of estimation theory [28  ###reference_b28###], thanks to the introduced diversity gain. Last but not least, the interpretation of any motion effect sensed over a reflection path is clearly defined without any ambiguity.\nOf course, exploiting monostatic sensing to enable integrated sensing and communication (ISAC) within Wi-Fi framework\nis far from straightforward; it faces three major challenges. First, the cost of removing LoS path interference is the self-interference from Tx to its own Rx (of the reflected Tx signals) within the same RF chain. Normal radars rely on ultra-wide bandwidth (hence nanosecond time resolution) to separate this Tx-interference [29  ###reference_b29###], which may not be available to Wi-Fi in the current or the next few generations. Second, fully addressing the first problem would entail a revamp of the conventional Wi-Fi hardware configuration (Fig. 2a  ###reference_sf1###),\nupgrading its front-end to handle the Tx-interference (Fig. 2b  ###reference_sf2###); yet directly implementing this with a commodity Wi-Fi NIC (network interface card) is nearly impossible.\nThird, though preserving the Wi-Fi MAC protocol is of primary importance for the sake of compatibility, minor yet critical tuning of the protocol details may be inevitable to, for example, toggle between sensing Rx and communication Rx.\n###figure_3### ###figure_4### ###figure_5### To this end, we propose ISAC-Fi as the first trial of enabling ISAC within the Wi-Fi framework. Essentially, we achieve Tx-Rx separation within the same RF chain so as to operate monostatic sensing over Wi-Fi communications; though derived from full-duplex radios [30  ###reference_b30###, 4  ###reference_b4###], our revision is critical as the original proposals fail to work under ISAC settings. We also work out two prototypes of ISAC-Fi: while full ISAC-Fi makes use of USRP X310 [31  ###reference_b31###] to emulate a future implementation of Wi-Fi NIC shown in Fig. 2b  ###reference_sf2###, partial ISAC-Fi applies a plug-and-play (PnP) module to an arbitrary Wi-Fi NIC, delivering a backward compatibility while rendering conventional NICs ISAC-ready. Finally, we fine-tune the existing Wi-Fi MAC protocols so that both individual and distributed sensing are fully operational without affecting conventional Wi-Fi communications. In summary, we make six major contributions in this paper:\nWe propose ISAC-Fi as a Wi-Fi based ISAC prototype; it offers, for the first time, the monostatic sensing mode in addition to the commonly adopted bistatic mode.\nWe design a novel RF front-end to replace the current Wi-Fi design, in order to effectively separate the concurrent sensing and communication signals.\nWe propose critical revisions to both Wi-Fi MAC protocol and sensing algorithms for maintaining compatibility.\nWe implement a full prototype of ISAC-Fi leveraging the universal emulation capability of USRP X310.\nWe also implement a partial prototype of ISAC-Fi; it attaches a PnP module to any existing Wi-Fi NIC in order to elevate it to be ISAC-ready.\nWe perform extensive experiments with both prototypes to validate their effectiveness and also to demonstrate their superiority over existing Wi-Fi sensing proposals.\nThe rest of our paper proceeds as follow. We first motivate our ideas by exposing the weaknesses of existing Wi-Fi sensing\nin Sec. II  ###reference_###. Then we explain our design of the novel RF front-end and the two prototypes of ISAC-Fi in Sec. III  ###reference_###. We further validate the individual functionalities of both prototypes in Sec. IV  ###reference_### and compare them with existing Wi-Fi sensing proposals in Sec. V  ###reference_###. We briefly discuss a few related proposals, along with limitations of ISAC-Fi in Sec.

Further reasoning could deduce that all normal directions lie on hyperbolas confocal with (hence orthogonal to) the ellipsoids, which can be deemed as the field lines of this field.\n###figure_10### Although it is highly nontrivial to experimentally characterize this field, verifying the ambiguity in sensing motion direction can be readily obtained by well-controlled experiments.

A full version integrates both sensing and communication functions, so two Rx chains are merged into one and all signal paths represented by dashed lines disappear. However, as the full version requires revamping the design of Wi-Fi NICs, we also offer a partial version with backward compatibility: it appends a special Sensing Module to an arbitrary Wi-Fi NIC.\nThough inspired by full-duplex radios [30  ###reference_b30###], our Tx-Rx separator differs significantly from it in that the Rx (monostatic sensing) signal to be extracted is, instead of arbitrary Rx signal, the reflection of the (slightly earlier) Tx signal. For the full version, we adopt a Circulator at the first stage to physically separate Tx and Rx, whereas we employ a Hybrid Coupler in the partial version to isolate Rx signal before feeding it to the sensing module. Other components for suppressing the residue Tx-interference are shared by both versions. We elaborate the two cancellators in Sec. III-B  ###reference_###, with an emphasis on preserving the monostatic sensing signal.\nThe sensing module has to be compatible with the Wi-Fi framework; in particular, the Analog/Digital Cancellators should not operate under the reception (hence bistatic) mode.

We first observe that almost the entire Tx-interference  comes from hardware circuits rather than the antenna. We perform two experiments where RF absorbing materials are used to surround an antenna in one case, and the antenna is replaced by an RF dummy load to stop radiating RF signals in another case. We compare the Tx-interference under these two cases in Fig. 10a  ###reference_.sf1###: the correlation coefficients between them are over 90%, proving that the antenna has almost no impact on the Tx-interference.

We adopt LTC5589 [41  ###reference_b41###] as the DQM; it enables direct modulation of IQ baseband signals at 2.4\u200b GHz carrier frequency and its Serial Peripheral Interface can be used to control the Tx gain, supply current, phase imbalance, etc. While the\ndigital cancellator is run by the SDR, we further design a General Purpose Input/Output board based on STM32 (an ARM-based MCU) to control the self-adapted Tx-Rx separation involving an RF switch HMC545A [42  ###reference_b42###]; the STM32 is in turn controlled by a host PC via USB.\nMonostatic sensing algorithms handling irregular packets (as presented in Sec. III-D  ###reference_###) are implemented in PC, and we further realize the collaborative sensing based on\nMQTT [43  ###reference_b43###], a lightweight publish/subscribe messaging protocol for remote devices information exchange.\nFor the full version, we implement the whole Wi-Fi OFDM PHY supporting 20\u200b MHz bandwidth, constellations from BPSK to 64 QAM, and all channel codes (with 1/2, 2/3, 3/4, and 5/6 coding rate).\nTo let monostatic sensing compatible with CSMA/CA, ISAC-Fi stays normal (the C-state defined in Sec. III-C  ###reference_###), and leverages the Received Signal Strength Indicator to determine whether a channel is idle. When transmitting data packets, the monostatic sensing (the M-state) is invoked to enable the Tx-Rx separator; the transition back to the C-state is triggered by a timer, or the completion of transmission (maximum Wi-Fi frame duration 5.484\u200b ms [44  ###reference_b44###]), whichever is sooner.\nBistatic sensing (the B-state) is triggered by packet receptions from another Wi-Fi NIC, and the transition back to the C-state naturally follows the completion of reception.\nFor the partial version, LimeSDR acts as the sensing module, while ESP32 [45  ###reference_b45###] (an ARM-based MCU with integrated Wi-Fi) is chosen as the Wi-Fi NIC, which already offers the Wi-Fi protocol stack.\nTo synchronize LimeSDR and ESP32, we design an external 40\u200b MHz clock board based on a Temperature Compensated Crystal Oscillator SiT5356 [46  ###reference_b46###].\nMost state transitions are the same as the full version except for the trigger for transiting to the M-state: when the host PC demands the Wi-Fi NIC to transmit data packets via hardware USB interrupt, it also invokes LimeSDR to the start the Tx-Rx separator simultaneously."

It can be observed that the analog and digital cancellators further reduce the Tx-interference by 40\u200b dB and 25\u200b dB, respectively. To sum up, the total cancellation is about 77\u200b dB, and the power of residue Tx-interference after Tx-Rx separator is very close to the noise floor.\n###figure_26### We also perform an experiment to study the impact of different Tx signal power on the Tx-Rx separator. We set the parameters of the Tx-Rx separator based on different Tx signal power to keep the power of residue Tx-interference close to noise floor, and plot the cancellation in Fig. 16  ###reference_###. Apparently, we can leverage linear regression to model the relationship between Tx power and cancellation, and hence, ISAC-Fi automatically selects parameters for the Tx-Rx separator. Since the residue Tx-interference is close to the noise floor after the Tx-Rx separator, the sensing performance is unaffected by the different Tx power.\nWe then study the impact of Tx-Rx separation on Wi-Fi communication, leveraging UDP-based video streaming and online gaming as the testing scenarios since TCP conceals packet loss. Specifically, the USRP-based full version, as it cannot be configured to operate in a multistatic setting, is evaluated by video streaming,\nand the partial version is evaluated by both video streaming and online gaming\nwith at least 3 users/players.\nThese experiment settings are employed to conduct all remaining experiments.\nEvaluation results of packet delay and packet loss rate are shown in Fig. 17  ###reference_###. The results show that, though ISAC-Fi leverages data packets to perform sensing, it achieves almost the same communication performance as normal Wi-Fi, demonstrating a zero-interference from sensing to communication.\nNote that in the experiments, the signals are intentionally attenuated by wall blockage to generate discernible results on packet loss; otherwise they are mostly always 0%.\n\u200b\u200b\n###figure_27### ###figure_28###"

To validate the claimed performance of ISAC-Fi, we let the robot car move at different speed range from 0.6\u200b m/s to 3.5\u200b m/s in a hall of , and we set a 10\u200b m spacing between two ISAC-Fi devices to measure the velocity using monostatic sensing.

Nonetheless, existing bistatic sensing proposals fail to totally fulfill the critical demands raised by this challenging application, mainly due to its incompetence in accurately estimating temporal features (as explained in Sec. II-A  ###reference_###). Therefore, we choose mD-Track [9  ###reference_b9###] (the latest bistatic sensing proposal on device-free sensing) as the comparison baseline in this section, intending to demonstrate the advantage of ISAC-Fi\u2019s monostatic sensing over bistatic sensing. In addition, the calibration algorithms of bistatic sensing mode are presented in mD-Track [9  ###reference_b9###].\n\u200b\u200b\n###figure_33### ###figure_34### We move the robot car to 16 preset locations in a 100 \u200bm2 lab space.

Subsequently, channel features are jointly estimated to derive AoA, ToF, and hence the location.\nFor each location, we average 40 measurements to derive an error by comparing with the ground truth, so as to derive 100 such errors with 4,000 measurements.\nAs ISAC-Fi excels at ToF estimation, we report the CDFs of both localization and ToF errors in Fig. 20  ###reference_###, comparing mD-Tracks with two ISAC-Fi localization schemes: while  leverages both ToF and AoA estimated by a single device to infer location,  exploits two collaborative devices to reach the same goal, while jointly estimating their mutual LoS distance at the same time.\nAs expected, ISAC-Fi outperforms mD-Track with a median localization error down to 1.12 \u200bm as opposed to mD-Track\u2019s 4.57 \u200bm, and  performs slightly better than  due to the collaborative sensing. These results are consistent with our analysis in Sec.

However, due to the ambiguities of bistatic motion sensing mentioned in Sec. II-C  ###reference_###, such translations can be misled and thus resulting in degraded performance. Therefore, we want to demonstrate using experiments that ISAC-Fi\u2019s monostatic sensing, albeit relying on only a single Wi-Fi device, may achieve comparable or even better performance than existing bistatic solutions with at least two devices involved.\nIn fact, basic HAR may not be a perfect task for evaluating sensing capabilities, because\nconventional bistatic Wi-Fi systems may still yield a high accuracy by overfitting the training/validation data.\nTherefore, we choose a more difficult cross-domain HAR task for evaluation, where cross-domain means that the environments and human subjects used in training and testing can be different. It is known that Wi-Fi signals carry a substantial amount of environment and subject specific information, so a Wi-Fi HAR method has to resolve this entangled information in order to generalize to new domains. Consequently, we select EI [13  ###reference_b13###] as the comparison baseline given i) its cross-domain capabilities achieved by the novel adversarial learning, and ii) its minimal 1Tx - 2Rx multistatic setup for Wi-Fi sensing.\nWe conduct experiments under several typical indoor settings.

Without loss of generality, the activities include sitting down, standing up, walking, falling down, bending, and lying down. Each activity is performed 2,500 times, and we obtain a total of 15,000 examples of these activity classes.

The results clearly highlight the efficacy of ISAC-Fi in resolving such ambiguities, allowing it to achieve a higher accuracy in cross-domain HAR."

Since these proposals often rely on increasing antenna numbers to improve performance, it is almost impossible to quantitatively compare among them. Consequently, we only demonstrate the feasibility of imaging with ISAC-Fi\u2019s novel monostatic sensing in the following. Specifically, we employ the deep learning techniques adopted by [56  ###reference_b56###] to translate CSIs captured by ISAC-Fi towards images outlines and skeletons of the subjects.\nWe conduct experiments in rooms and corridors. To enable Wi-Fi imaging, ISAC-Fi leverages its 3-antenna array to improve the spatial diversity in perceiving a subject. We ask human subjects to pose differently at various distances and angles. For each scene, ISAC-Fi averages over 300 packets to obtain a  CSI matrix, where the first two 3\u2019s refer to the antenna number and 150 indicates that 3 packets as a group with only 50 out of 64 subcarriers per packet are used. Meanwhile, a camera next to ISAC-Fi captures a ground truth photo. Since we are interested in outlines and skeletons of human subjects, the photos are further processed to generate binary masks and skeletons of the human subjects for training purposes. We collect a total of 10,000 CSI-image pairs for training deep neural network.\n###figure_37### Since all spatial information is embedded in the CSI samples, it is viable to reconstruct human image (outline) and skeleton from its corresponding CSI sample leveraging the deep learning network designed in [56  ###reference_b56###]. The network treats the  CSI samples as  images with 150 channels.\nIt trains a U-Net [57  ###reference_b57###] and skeleton association algorithm [58  ###reference_b58###] to map the CSIs to outlines and skeletons, leveraging the training data created from ground truth photos.

The RF images correctly indicate the number of subjects and clearly show the torso, head, and limbs of each subject, while the skeleton images provide an even sharper characterization of the joint and limb positions. All these results confirm the imaging capabilities of the monostatic sensing adopted by ISAC-Fi. We believe that more realistic imaging results can be achieved if we combine both monostatic and bistatic sensing, but we leave this task to interested researchers."

[64  ###reference_b64###, 65  ###reference_b65###].\nWhile device-based methods are mainly applied to locate Wi-Fi devices, device-free methods impose no requirement on users but entail a bistatic or even multistatic setting, which often fails to support full-fledged Wi-Fi ISAC systems due to their technology deficiencies such as capable of handling only one person.\nMoreover, existing proposals on device-free Wi-Fi sensing have largely remained as experimental prototypes because sensing algorithms are often at odd with Wi-Fi communications. For example, Wi-Vi [10  ###reference_b10###] applies two Tx antennas to null all static signal/interference and hence totally loses its communication capability. Our ISAC-Fi is specifically proposed and implemented to tackle the challenges faced by existing device-free methods, and it also aims to seamlessly integrate sensing with communication so as to realize the first ISAC-ready Wi-Fi prototype. More importantly, ISAC-Fi can provide more diversified information\nby combining monostatic with bi/multistatic sensing modes.\nAlthough ISAC-Fi has learned from earlier developments on full-duplex radios (FDR)  [66  ###reference_b66###, 30  ###reference_b30###, 67  ###reference_b67###], separating Tx (communication) from Rx (sensing) is fundamentally different from FDR as explained in Sec. III-B  ###reference_###. Recent surveys present the architectures, challenges, and opportunities of FDR for future 6G [68  ###reference_b68###, 69  ###reference_b69###]. Early proposal WiDeo [4  ###reference_b4###] leverages a modified version of FDR to conduct only motion sensing, so it is unable to both locate static subjects and remain compatible with Wi-Fi communications. The closest (title-wise) proposal to our ISAC-Fi in recent literature is [70  ###reference_b70###], yet it merely migrates FDR technique to ISAC scenarios without paying attention to their fundamental differences. Also, the authors in [70  ###reference_b70###] never consider the compatibility with Wi-Fi framework and it relies on a proprietary chip for Tx-Rx separation; these have strongly confined its practical feasibility.\nOn the contrary, our ISAC-Fi prototypes deploy a critical revision to FDR (see Sec. III-B  ###reference_###) and aim to maintain a full compatibility with Wi-Fi communications (see Sec. III-C  ###reference_### and III-D  ###reference_###), so they are clearly implementable as extended Wi-Fi NICs with necessary manufacturer support.\nIt is true that 802.11ax can support 160 \u200bMHz at 5 \u200bGHz, yet the whole 160 \u200bMHz is not always usable due to channel contention. As a result, most of the IoT devices are still leveraging 20 \u200bMHz bandwidth at 2.4 \u200bGHz to communicate with each other. Consequently, we start with a basic and common 20 \u200bMHz bandwidth to design the first full-fledged ISAC system. To the best of our knowledge, our work is pioneering in enabling full-fledged sensing modes over Wi-Fi communication. In other words, we mainly demonstrate design principles in this seminal paper, aiming to deliver guidance for engineering design in future. In this sense, achieving a wider bandwidth (e.g., 160 \u200bMHz for 802.11ax) should not be the focus of our paper; it is only an engineering extension that can be realized upon our basic design framework by future studies with specific need for it. In fact, a few other challenges still remain for monostatic sensing, such as realizing a large-scale MIMO front-end (e.g., millimeter wave [71  ###reference_b71###]), and wide-scale distributed MIMO; we also leave these as key directions for our further explorations."

In recent years, significant progress has been made on deep learning under DP [3  ###reference_b3###, 4  ###reference_b4###, 5  ###reference_b5###, 6  ###reference_b6###]. While the practical performance continues to improve, the theoretical analysis lags behind. Existing analyses focus primarily on Lipschitz loss functions, such that the gradients are all bounded [7  ###reference_b7###, 8  ###reference_b8###, 9  ###reference_b9###, 10  ###reference_b10###]. However, many empirical studies have shown that in deep learning, gradient noise usually follows heavy-tailed distributions [11  ###reference_b11###, 12  ###reference_b12###, 13  ###reference_b13###, 14  ###reference_b14###]. To bridge the gap between theory and practice, it is worth investigating the DP stochastic optimization problem with heavy tails.\nIt has been shown in [1  ###reference_b1###] that if the stochastic gradients have bounded -th order moments for some , then the minimax lower bound of optimization risk is  under -DP, which can be viewed as the theoretical limit of DP optimization. However, existing methods fail to achieve this rate. Compared with Lipschitz loss functions, a crucial challenge in analyzing heavy-tailed gradients is the design of an efficient mean estimator under DP. Various methods for DP mean estimation have been proposed [15  ###reference_b15###, 16  ###reference_b16###, 17  ###reference_b17###, 18  ###reference_b18###]. These methods have achieved optimal mean squared error, but the high probability bounds are not optimal. To bound the risk of optimization, we need a union bound of the bias and variance of gradient estimate over the whole hypothesis space. Therefore, a suboptimal high probability bound of mean estimation results in a suboptimal risk of optimization. To be best of our knowledge, currently, it is unknown whether the minimax lower bound shown in [1  ###reference_b1###] is achievable.\nIn this paper, we answer this question affirmatively. We propose two methods, called the simple clipping method and the iterative updating method, respectively. For both methods, we derive the high probability bounds of mean estimation first, and then analyze the risk of optimization.\n1) Simple clipping. This method just clips all gradients to a given radius  and calculates sample averages.  can be tuned based on the privacy requirement  and the number of samples . Our analysis shows that the population risk is , which improves over existing methods. This rate matches the minimax lower bound if , under which the third term  does not dominate. The key of such improvement is that we treat the tail behavior of mean estimation more carefully. In particular, we show that the mean estimation has a subexponential tail in all directions, which refines the union bounds and eventually leads to the risk bound mentioned above. The remaining drawback is that this method has an additional term . Therefore, this method is suboptimal if .\n2) Iterative updating. This method is proposed to remove the additional term of the simple clipping method. It divides the data into  groups. For each group, this method calculates the group-wise mean and adds noise to meet DP requirements. After that, the mean estimate is iteratively updated based on the estimation of distances and directions to the ground truth . Such design is inspired by several existing methods for non-private mean estimation with heavy-tailed data [19  ###reference_b19###, 20  ###reference_b20###, 21  ###reference_b21###, 22  ###reference_b22###]. Compared with the simple clipping approach, this method improves the tail behavior of the mean estimator from subexponential to subgaussian. Moreover, this method is invariant to permutations of groups. As a result, the overall privacy of the final estimate is amplified compared with the privacy of each group [23  ###reference_b23###, 24  ###reference_b24###]. With this new algorithm and refined theoretical analysis, we achieve a risk bound , matching the minimax lower bound.\nOur results and comparison with existing works are summarized in Table I  ###reference_###. To the best of our knowledge, our methods achieve the optimal risk of stochastic convex optimization problems under DP for the first time."

Early works focus on empirical risk minimization (ERM) under DP, which is a relatively simpler problem compared with stochastic optimization, such as [26  ###reference_b26###, 27  ###reference_b27###, 28  ###reference_b28###, 7  ###reference_b7###, 29  ###reference_b29###, 30  ###reference_b30###]. For stochastic optimization problem, [8  ###reference_b8###] shows that for Lipschitz loss functions, DP-SGD is minimax optimal with proper parameter selection. The analysis is then improved in several later works on time complexity [31  ###reference_b31###, 32  ###reference_b32###] and extended to different geometries [33  ###reference_b33###, 34  ###reference_b34###]. For heavy-tailed gradients, the non-private optimization has been widely studied [35  ###reference_b35###, 13  ###reference_b13###, 36  ###reference_b36###, 37  ###reference_b37###, 38  ###reference_b38###, 39  ###reference_b39###, 40  ###reference_b40###, 41  ###reference_b41###, 42  ###reference_b42###, 43  ###reference_b43###]. Under DP, [25  ###reference_b25###] provides the upper bound of DP-SGD under the assumption that gradients have bounded second moments. [44  ###reference_b44###] analyzes the sparse setting. [1  ###reference_b1###] improves on the risk bound. Moreover, [45  ###reference_b45###] weakens the uniform Lipschitz assumption to a sample-wise one.\nMean estimation with subgaussian rates. Non-private mean estimation for heavy-tailed distributions has received widespread attention [46  ###reference_b46###]. We hope to minimize the  high probability bound of the estimation error. [47  ###reference_b47###] shows that the median-of-means method achieves an error bound of  with probability . [19  ###reference_b19###] improves the bound to  for the first time, but the method in [19  ###reference_b19###] is computationally expensive. After that, improved algorithms with the same high probability bounds and faster computation are proposed in [20  ###reference_b20###, 21  ###reference_b21###, 22  ###reference_b22###]. Note that this rate is minimax optimal. [48  ###reference_b48###] shows that the lower bound of estimation error with  probability is  for  samples.\nCompared with non-private mean estimation, we need to randomize samples carefully to achieve a tradeoff between accuracy and privacy. This involves a refined analysis of tail behaviors, as well as privacy amplification by shuffling. As a result, we finally achieve optimal rates of DP optimization with heavy-tailed gradients."

+    "title": "Active Learning for Identifying Disaster-Related Tweets: A Comparison with Keyword Filtering and Generic Fine-Tuning",
+    "abstract": "Information from social media can provide essential information for emergency response during natural disasters in near real-time. However, it is a difficult task to identify the disaster-related posts among the large amounts of unstructured data available. Previous methods often use keyword filtering, topic modelling or classification-based techniques to identify such posts. Active Learning  (AL)presents a promising sub-field of Machine Learning  (ML)that has not been used much in the field of text classification of social media content. This study therefore investigates the potential of AL for identifying disaster-related Tweets. We compare a keyword filtering approach, a RoBERTa model fine-tuned with generic data from CrisisLex, a base RoBERTa model trained with AL and a fine-tuned RoBERTa model trained with AL regarding classification performance. For testing, data from CrisisLex and manually labelled data from the 2021 flood in Germany and the 2023 Chile forest fires were considered. The results show that generic fine-tuning combined with 10 rounds of AL outperformed all other approaches. Consequently, a broadly applicable model for the identification of disaster-related Tweets could be trained with very little labelling effort. The model can be applied to use cases beyond this study and provides a useful tool for further research in social media analysis.",

+            "text": "Identifying important contents among vast amounts of information has been a central research topic in many disciplines including the digital and analytical sciences. Berners-Lee [5  ###reference_b5###] argues that \"[i]nformation about information is powerful not just as information, but because it allows one to leverage one\u2019s use of information\". As a result, numerous methods have been developed to query and filter various types of data as efficiently as possible [8  ###reference_b8###, 16  ###reference_b16###].\nSimultaneously, social media has become one of the most prevalent and abundant data sources in modern times [34  ###reference_b34###]. Geo-referenced social media data in particular has proven to be a vital source of data before, during and after the occurrence of natural disasters. Emergency responders, official entities and aid organisations can use social media platforms to intercept information in near real-time. This includes texts and imagery with potentially valuable information [28  ###reference_b28###]. Given the complexity of natural language, even seemingly simple tasks such as identifying the posts that are related to the disaster pose a challenging task. To solve it, numerous methods have already been proposed in the literature, ranging from naive keyword filtering [45  ###reference_b45###] to advanced techniques such as topic modelling [17  ###reference_b17###] or classification using neural networks [31  ###reference_b31###]. Overall, the majority of methods in the current literature can be categorised as Machine Learning (ML).\nSince the identification of disaster-related Tweets is generally a binary classification task, the use of unsupervised techniques such as topic modelling might not yield consistent results because they are highly dependent on the data set [2  ###reference_b2###]. Simultaneously, many supervised learning approaches require considerable amounts of training data, resulting in extensive labelling efforts to train a high-quality model. For this reason, Active Learning  (AL)has gained increasing popularity. It describes a semi-supervised learning approach in which the model chooses the samples to label instead of humans. This minimises the amount of labelled data needed to achieve high model performance [24  ###reference_b24###]. Throughout Active Learning (AL), borderline cases are also presented to the annotator which can guide and thereby improve the learning process.\nSo far, AL has rarely been used in the context of social media analysis. Paul et al. [38  ###reference_b38###] show that it can yield promising results for the identification of disaster-related Tweets. However, their study is limited to one data set and they do not explicitly evaluate their outputs for different kinds of natural disasters. Furthermore, their AL approach is not compared to other methods of filtering. To fill this research gap, we aim to answer the following research question: How does an AL-based approach compare to keyword filtering or fine-tuning using a broad generic data set for the classification of disaster-related Tweets?"

Numerous methods have already been developed for the detection of events, e.g. by Saeed et al. [42  ###reference_b42###].\nSome of these approaches rely on a simple keyword-filtering in combination with thresholds [50  ###reference_b50###] or are based on disaster-related hashtags [41  ###reference_b41###]. Chen et al. [7  ###reference_b7###] introduce a keyword-based query strategy that iteratively updates the keyword list by ranking Term Frequency-Inverse Document Frequency (TF-IDF) weights from previously identified posts. Yigitcanlar et al. [55  ###reference_b55###] base their analysis of disaster-related Tweets in Australia on word frequency and co-occurrence.\nMore advanced approaches based on ML algorithms have also been devised.\nHavas et al. [17  ###reference_b17###] use the probabilistic Latent Dirichlet Allocation (LDA) method to model topics in Tweets for near real-time monitoring of natural disasters. This approach is also used by Sit et al. [51  ###reference_b51###] in combination with a Long Short-Term Memory (LSTM) network to identify topics in Tweets about Hurricane Irma. Saleem et al. [44  ###reference_b44###] use BERTopic, a topic modelling approach based on Bidirectional Encoder Representations from Transformers (BERT), to identify relevant topics for the 2023 Turkey earthquake.\nModels from the BERT family have generally been employed frequently in this domain. For example, de Bruijn et al. [10  ###reference_b10###] utilise BERT to detect flood events from social media posts.\nHuang et al. [21  ###reference_b21###] identify emergency-related posts on Sina Weibo by putting semantic representations from BERT into a Bidirectional LSTM (Bi-LSTM) network with an attention mechanism. One frequently used variant of BERT is the Robustly Optimized BERT Pre-training Approach (RoBERTa) which is based on an improved pre-training procedure resulting in an even better understanding of natural language [26  ###reference_b26###]. A RoBERTa model fine-tuned with the CrisisMMD data set is used by Koshy et al. [22  ###reference_b22###] in combination with a Vision Transformer model for imagery to categorise multimodal Twitter data. Madichetty et al. [30  ###reference_b30###] use RoBERTa and VGG-16 to classify textual and imagery content for various disasters including hurricanes and wildfires. Multiplying the output class probabilities, they fuse this information to identify informative Tweets. Adwaith et al. [1  ###reference_b1###] compare multimodal architectures for text and imagery, identifying a combination of RoBERTa and ResNet or DenseNet as most suitable.\nAdditionally, a Convolutional Neural Network (CNN) has been proposed by several authors, e.g. for anomaly detection in a global Twitter feed [52  ###reference_b52###] or to identify landslide imagery from social media [39  ###reference_b39###].\nGraph Neural Network (GNN)-based methods have also been developed, e.g. by Li et al. [25  ###reference_b25###] who combine textual and imagery content for their classifications. Papadimos et al. [37  ###reference_b37###] additionally include the timestamp into their GNN.\nSome of these methods have also been employed for the more specific task of relevance classification. Madichetty et al. [31  ###reference_b31###], for instance, develop a CNN to categorise disaster-related Tweets as either informative or uninformative."

Those samples are then annotated by an oracle, generally involving a human-in-the-loop. Subsequently, the model is updated using the newly labelled data [24  ###reference_b24###, 33  ###reference_b33###]. With the help of AL, a relatively high model accuracy can be achieved with little training data as redundant data points can be avoided by the appropriate query strategy. This, in turn, drives down the cost of labelling data [49  ###reference_b49###].\nA variety of query strategies have been developed for AL. Monarch and Manning [32  ###reference_b32###] distinguishes three types of strategies: random, uncertainty (selecting the instances with the lowest label certainty) and diversity (selecting the instances that are rare in the training data to broaden the training space). Implementations of those strategies that have successfully been utilised for language classification include [12  ###reference_b12###, 46  ###reference_b46###]:\nRandom sampling: Batch instances are chosen at random from the unlabelled training data set.\nLeast Confidence (LC): Selects the instances with the least prediction confidence [24  ###reference_b24###].\nPrediction Entropy (PE): Chooses instances that maximise the expected amount of information we gain about the set of unlabelled data points [20  ###reference_b20###].\nBreaking Ties (BT): Selects the instances that have the smallest margin between their most likely and second most likely predicted class, i.e. the ties [29  ###reference_b29###].\nGreedy Core-Set (GCS): Greedily selects the instances that best cover the data set in the learned representation space using the geometry of the data points [48  ###reference_b48###].\nDiscriminative Active Learning (DAL): Selects instances that make the batch most representative of the entire pool of unlabelled training instances using a binary classification setting [15  ###reference_b15###].\nEin-Dor et al. [12  ###reference_b12###] examine different query strategies for AL with BERT. While all AL strategies improve over the baseline of choosing samples randomly, no single strategy consistently outperforms all its counterparts. Nonetheless, various strategies yield different runtimes, sample diversity and representativeness concerning the full unlabelled pool of training data. DAL and GCS have been shown to deliver the most diverse batches. DAL additionally yields higher representativeness when compared to GCS. However, no direct connection between these measures and classification performance has been demonstrated, giving these results only theoretical value. Lowell et al. [27  ###reference_b27###] reveal the inconsistency of AL over independent and identically distributed (i.i.d.) sampling more explicitly. In a greater research context, AL has successfully been utilised and examined for a diverse range of tasks in natural language and image processing. Sahan et al. [43  ###reference_b43###] compare different types of uncertainty representations for text classification and fake news detection. Budd et al. [6  ###reference_b6###] investigate the role of humans in the development and integration of deep learning models for medical image analysis using AL. Ahmed et al. [3  ###reference_b3###] show that AL can be equally useful in centralised and federated learning environments. They further demonstrate that AL can be utilised independently of the data set by evaluating their method for natural disaster image and waste classification. For both applications, their AL method achieves competitive results when compared to the scenario that each sample is manually analysed and annotated."

[18  ###reference_b18###] and retrieved georeferenced Tweets using both the v1.1 REST and the streaming API.\nTo evaluate the performance of Tweet classification with AL, we decided to go with two use cases: In July 2021, one of the most devastating floods in recent German history took place in the Ahr valley in Rhineland-Palatinate [14  ###reference_b14###]. In early 2023, extensive forest fires raged in the Central South of Chile, particularly in the \u00d1uble, Biob\u00edo and La Araucan\u00eda regions.\nTo create our training and test data sets, we employed spatial and temporal filtering (cf. Table 1  ###reference_###).\nSince the area of interest (AOI) and timeframe were much larger for Chile, we obtained substantially more Tweets. For further processing, the data set was therefore pre-filtered using the keywords \"incendio\", \"fuego\" and \"fire\" to narrow down the search space for disaster-related Tweets. For evaluation, a fraction of the two data sets were manually labelled as \"related\" or \"unrelated\" to the disaster by two annotators with uniform inter-annotator agreement. In this study, a Tweet was only considered disaster-related if it contained reactions, impressions, commentaries or other explicit information about the respective natural disaster.\nMoreover, a generic data set of disaster-related and non-disaster-related Tweets was compiled that did not require any manual annotation. It was built upon data sets from CrisisLexT6 [35  ###reference_b35###] and CrisisLexT26 [36  ###reference_b36###], for which a label mapping as in Table 2  ###reference_### was created. Based on the re-labelled data sets, a class-balanced training data set was curated. Non-natural disasters (e.g. shootings or bombings) were excluded from the training data as they were irrelevant to the use cases in question. The final data set contained Tweets regarding earthquakes, volcanic eruptions, landslides, wildfires, floods and tropical storms. To further augment the data sets and improve the multilingual capabilities during training, the curated English-language training data was translated to Spanish, German, Italian and French using the M2M-100 translation model [13  ###reference_b13###] to obtain a multilingual joint data set consisting of 179\u2009391 training data points and 44\u2009848 test data points."

It was implemented using a basic containment check for each keyword that was applied to each string while casing was ignored. Table 3  ###reference_### shows the keywords used for each test data set.

AL addresses the lack of labelled training data for those scenarios and allows for the fine-tuning of the model\u2019s understanding of disaster-relatedness such that it aligns with the understanding of the user.\nTo test the effectiveness of AL for the classification task in question, two configurations were considered: (1) taking the untouched Twitter-XLM-RoBERTa as a base model and (2) taking the version that was fine-tuned with generic data as described in the previous section as a base model. These two distinct setups were chosen to evaluate if fine-tuning with generic data helps to speed up the AL process later on. For the main AL loop, 10\u2009983 Tweets from the Ahr Valley flood and a uniformly selected sample of 20\u2009000 Tweets from the Chile forest fires were taken as input. The Chile data set was downsampled quite heavily to achieve bearable runtimes for each AL iteration. Given this setup, AL was conducted using a GCS query strategy. It is based on a greedy computation of a subset of the unlabelled data points such that the geometric loss between the subset and the remaining data points is minimised [48  ###reference_b48###].\nFor both AL setups, 10 rounds of querying data, labelling and updating were performed. During each iteration, 20 unlabelled data points were returned to the human annotators. Additionally, 20 data points were labelled to train a first instance of the model preceding the AL process. Two persons participated in each part of the iterative labelling process to ensure the quality of the newly labelled training data.

For the generic test data set based on CrisisLex, the overall accuracy reached a value of 0.70. When looking at more detailed metrics, however, the method achieved very low recall values for class 1 (\"related\") and low precision for class 0 (\"unrelated\"). For the 2021 Germany flood data set, the approach worked best, even producing results that were comparable to the other filtering techniques. The results were also competitive for the 2023 Chile forest fire data set. Fuzzy keyword filtering only marginally improved the results of keyword filtering on the CrisisLex-based data set and barely resulted in a significant change in results in the other two data sets. For the 2023 Chile forest fire data, the results of hard and fuzzy keyword filtering were the same. For the purposes of this study, fuzzy keyword filtering thus did not yield any significant advantage.\nFine-tuning with generic data led to two-fold results. The classification performance for the respective CrisisLex-based test data set was high, yielding competitive values for all evaluation metrics. For the 2021 Germany flood test data, the GFT approach produced slightly higher recall when compared to keyword filtering but lower precision for class 1. For the 2023 Chile forest fire data set, the performance was slightly worse throughout the board. Here, the model was even outperformed by the keyword-filtering approach. This might be traced back to the fact that out of 20 disasters covered by the generic training data set, only two were wildfires.\nThe approach based solely on AL yielded unreliable results across the use cases. While its recall was very high for the CrisisLex data set for class 0 (0.98), it had a very low value for class 1 (0.27). The opposite was the case for the precision. It was noticeable that the scores were generally lower for class 1. The evaluation metrics were better for the Germany use case than for the Chile data set. Nevertheless, the AL model achieved the lowest accuracy scores for all data sets. However, these results are limited by the number of AL iterations and the relatively low number of data points labelled during each. This choice, though, was made on purpose in this study, as a lengthy and computationally expensive labelling process would defeat the purpose of AL for the rapid identification of disaster-related Tweets.\nOur approach combining GFT and AL scored the highest evaluation metrics. This was particularly the case for the Chile use case, where the model consistently outperformed all other approaches. For the Germany use case, the performance was considerably higher, although class 1 was around 10 percentage points worse than class 0. For the CrisisLex data set, the model performed slightly worse than the plain GFT model, with the exception of precision for class 1 and recall for class 0. Still, the lowest overall metric was a recall of 0.73 for class 1 in Chile, which was 8 percentage points higher than the lowest value in the plain GFT model. Given these results, AL significantly improved upon the GFT approach, especially for the Chile use case, and yielded a model that could be broadly applied to different disaster scenarios."

+            "text": "Although the filtering methods compared in this study are popular and established techniques for social media and text analysis, the choice of methods is not exhaustive. Numerous other methods have been utilised for this task including CNNs [52  ###reference_b52###], LSTMs [21  ###reference_b21###] and GNNs [37  ###reference_b37###]. Naturally, keyword filtering and transformer-based classification approaches are vastly different and have been developed in different time frames. However, keyword filtering still constitutes a simple and quick method for filtering or querying textual data. Compared to modern approaches, a keyword filter requires much less computational power and can easily be applied to large amounts of data residing in e.g. a database without further technical considerations.\nHowever, it comes with the fundamental problem of keyword selection. In addition, morphological restrictions (e.g. due to inflection), the multilingualism of a data set and the resulting polysemantics pose a particular challenge. Both problems are addressed by our AL and GFT approaches which do not require the identification of keywords and can handle multiple languages. Nevertheless, the results of this study show that keyword filtering can yield high performance for specific data when it has been investigated carefully and keywords are selected accordingly.\nThe GFT approach described in this study requires zero additional labelling effort and still leverages the advantages of modern Large Language Models (LLMs). However, it must be noted that such a generic data set might not be available for every use case. Although CrisisLex covers a fairly wide range of scenarios, some events such as avalanches might not be reflected in the generic training data, limiting the model\u2019s suitability for such scenarios. In such a case, manual labelling would once again be necessary, defeating the purpose of fine-tuning with generic data. On the other hand, GFT holds a large potential for transfer learning which is leveraged in this study by subsequent AL and making the classification model multilingual. While the GFT model trained for this study can theoretically also be applied to texts written in Non-Indo-European languages, the performance and transferability of a fine-tuned Twitter-XLM-RoBERTa model on such languages are subject to further studies. A study by Zheng et al. [56  ###reference_b56###] has already shown large differences in accuracy of approximately 15 percentage points between Indo-European and Non-Indo-European languages.\nAL also comes with its unique challenges. There are numerous query strategies and none of them has been proven to be generally superior to the other. On a use case basis, different query strategies can yield varying results. The query strategy must therefore be carefully chosen by the user, though every strategy is better than random sampling [12  ###reference_b12###]. During the implementation of this study, the GCS strategy provided superior results compared to other strategies such as LC and also came with better runtimes. It was therefore chosen for the final evaluation.\nThe AL process conducted for this study was furthermore quite inconsistent as depicted by Fig. 2  ###reference_###. The pure AL model dropped in accuracy for the first few rounds and only yielded competitive performance after the tenth round. The case was similar for the combined AL + GFT approach with performance losses for the first few rounds and slight increases afterwards. It also experienced a sharp drop in test accuracy after the ninth round of AL and a subsequent sharp increase. The F1 scores experienced similar inconsistencies and even dropped to 0.00 for the first few rounds of the pure AL approach.\nLastly, the field of language processing is changing rapidly and novel methods for few-shot classification [47  ###reference_b47###] and zero-shot classification with the help of generative LLMs [54  ###reference_b54###] have rapidly gained popularity. Although these methods have not yet generally outperformed more traditional classification approaches and AL, they are subject to future investigations. In the context of AL, generative LLMs might also be useful for automating the annotation of training examples."

For evaluation, we compared three data sets: a generic collection of Tweets from CrisisLex, Tweets from the 2021 West Germany Flood, and Tweets from the 2023 Chile forest fires.\nWe found that simple keyword filtering produces good results in many cases, but is fundamentally inferior to RoBERTa-based methods. A fuzzy approach did not improve our keyword filtering-based results.\nWe observed clear differences between our use cases. The classification of the Tweets from Germany generally worked better than for the Spanish-language data from Chile. Our plain AL model performed the worst out of all approaches, though, for some parts of the data, the differences to some of the other techniques were small, especially for the Chile data set.\nThe approach combining AL with an already fine-tuned RoBERTa model achieved the best performance across most evaluation metrics. In particular, for the Chile use case, it significantly outperformed the generically fine-tuned model, which scored even worse than simple keyword filtering. The approach was also superior to all other methods for the Germany use case and produced competitive results when applied to generic test data based on CrisisLex.\nConsequently, we can verify that combining AL with a generic fine-tuning approach is a well-suited strategy for the identification of disaster-related Tweets. The approach required very little labelling of data and outperformed all other methods for the data tested in our study."

+    "abstract": "This paper presents the SZU-AFS anti-spoofing system, designed for Track 1 of the ASVspoof 5 Challenge under open conditions. The system is built with four stages: selecting a baseline model, exploring effective data augmentation (DA) methods for fine-tuning, applying a co-enhancement strategy based on gradient norm aware minimization (GAM) for secondary fine-tuning, and fusing logits scores from the two best-performing fine-tuned models. The system utilizes the Wav2Vec2 front-end feature extractor and the AASIST back-end classifier as the baseline model. During model fine-tuning, three distinct DA policies have been investigated: single-DA, random-DA, and cascade-DA. Moreover, the employed GAM-based co-enhancement strategy, designed to fine-tune the augmented model at both data and optimizer levels, helps the Adam optimizer find flatter minima, thereby boosting model generalization. Overall, the final fusion system achieves a minDCF of 0.115 and an EER of 4.04% on the evaluation set.",

progress has resulted in a proliferation of forgeries that can be almost indistinguishable from authentic speech to the human auditory system.\nConcurrently, automatic speaker verification (ASV) systems have become increasingly susceptible to spoofing and deepfake attacks, in which attackers produce convincingly realistic simulations of the target speaker\u2019s voice [1  ###reference_b1###].\nThe potential misuse of spoofed speech presents significant societal risks.\nTherefore, developing a robust and generalizable anti-spoofing system to counter these threats has emerged as a critical research imperative.\nThe ASVspoof challenges [2  ###reference_b2###, 3  ###reference_b3###, 4  ###reference_b4###, 5  ###reference_b5###, 6  ###reference_b6###] have significantly boosted interest in developing robust detection solutions for spoofing and deepfake attacks, thereby enhancing the security and reliability of ASV systems.\nThese challenges provide standardized benchmark protocols and comprehensive evaluation datasets.\nWhat\u2019s more, the last four ASVspoof challenges [2  ###reference_b2###, 3  ###reference_b3###, 4  ###reference_b4###, 5  ###reference_b5###] have prompted the proposal of numerous innovative spoofing detection methods [7  ###reference_b7###, 8  ###reference_b8###, 9  ###reference_b9###, 10  ###reference_b10###].\n###figure_1### Held in 2024, the ASVspoof 5 Challenge [6  ###reference_b6###] presents two distinct conditions, open and closed, for both Track 1 which focuses on standalone speech deepfake detection, and Track 2 which is dedicated to spoofing-robust automatic speaker verification.\nUnder the closed conditions, participants are restricted from using specified data protocols.\nConversely, the open conditions offer greater flexibility, allowing participants to utilize external data and pre-trained self-supervised models, provided there is no overlap between training data (i.e., that used for training foundational models) and evaluation data.\nTrack 1 is similar to the DF track of the ASVspoof 2021 Challenge, reflecting a scenario in which an attacker has access to a targeted victim\u2019s voice data, such as data posted on social media.\nIn this scenario, the evaluation set contained data processed with conventional codecs or modern neural codecs.\nTrack 2, similar to the LA sub-task from previous ASVspoof challenges, is predicated on a telephony scenario where synthetic and converted speech is directly injected into a communication system without any acoustic propagation.\nThe ASVspoof 5 Challenge introduces significant changes in source data, attack types, and evaluation metrics.\nThe source data, extracted from the Multilingual Librispeech English partition [11  ###reference_b11###], includes a vastly greater number of speakers than previous ASVspoof databases.\nNotably, the spoofing attacks in the training, development, and evaluation sets are entirely disjoint.\nAs shown in Table 1  ###reference_###, the training dataset is used to adjust model parameters, while the development dataset is used to tune and evaluate performance.\nThe progress set initially assesses the detection model\u2019s performance, allowing participants up to four submissions per day via the Codalab platform.\nThe evaluation set tests its generalizability, with only one submission allowed per team.\nNew evaluation metrics, minDCF [12  ###reference_b12###] for Track 1 and agnostic DCF [13  ###reference_b13###] for Track 2, have been introduced to better assess anti-spoofing systems.\nThis paper presents the SZU-AFS anti-spoofing system for Track 1 under open conditions.\nIts design diagram is illustrated in Figure 1  ###reference_###, where model IDs are labeled from A to D, with numbers indicating their respective versions.\nThis system has four stages: baseline model selection, exploration of effective data augmentation (DA) methods for fine-tuning, application of a co-enhancement strategy utilizing gradient norm aware minimization (GAM) for secondary fine-tuning, and fusion of logits scores from the two top-performing models.\nSpecifically, comparative experimental analysis was conducted first by combining three pre-trained models with three distinct classifiers to select an appropriate baseline model.\nWe have selected the pre-trained Wav2Vec2 model [14  ###reference_b14###] as the feature extractor, coupled with the AASIST classifier [15  ###reference_b15###], to serve as the baseline model (A9).\nSecondly, we have proposed three DA policies to explore the effectiveness of various DA methods: single-DA, random-DA, and cascade-DA.\nThe best-performing model is the one fine-tuned by augmented data generated by sequentially applying room impulse response (RIR) noise and time masking (TimeMask) method, resulting in an augmented model (B5).\nNext, we employed a GAM-based co-enhancement strategy to consider data and optimizer simultaneously to enhance model generalizability.\nWith this strategy, the B5 model has been fine-tuned by combining various DA methods with the GAM method, resulting in the C11 and C12 models as the two best-performing fine-tuned models.\nFinally, we have fused the predicted logits scores from the C11 and C12 models using an average score-level fusion method to generate final evaluation scores, constituting system D4.\nThis paper is organized as follows:\nSection 2  ###reference_### elaborates the core modules of the SZU-AFS system, including the baseline model, the three DA policies, the GAM-based co-enhancement strategy, and the score-level fusion.\nImplementation details regarding the dataset information and model hyperparameters are provided in Section 3  ###reference_###.\nSection 4  ###reference_### provides experimental results and analysis.\nConclusions are drawn in Section 5  ###reference_###."

+    "abstract": "This paper addresses the problem of selecting the minimum number of dedicated sensors to achieve observability in the presence of unknown inputs, namely, the state and input observability, for linear time-invariant systems. We assume that the only available information is the zero-nonzero structure of system matrices, and approach this problem within a structured system model. We revisit the concept of state and input observability for structured systems, providing refined necessary and sufficient conditions for placing dedicated sensors via the Dulmage-Mendelsohn decomposition. Based on these conditions, we prove that determining the minimum number of dedicated sensors to achieve generic state and input observability is NP-hard, which contrasts sharply with the polynomial-time complexity of the corresponding problem with known inputs. We also demonstrate that this problem is hard to approximate within a factor of , where  is the state dimension. Notwithstanding, we propose nontrivial upper and lower bounds that can be computed in polynomial time, which confine the optimal value of this problem to an interval with length being the number of inputs. We further present a special case for which the exact optimal value can be determined in polynomial time. Additionally, we propose a two-stage algorithm to solve this problem approximately. Each stage of the algorithm is either optimal or suboptimal and can be completed in polynomial time.",

+            "text": "State observability is a fundamental problem in control theory that has been extensively studied since the work of Kalman [1  ###reference_b1###]. Over time, the scope of observability problem has expanded to encompass novel concepts, including state observability, state and input observability, functional observability and so on. These extensions hold significant importance in control law synthesis, fault detection and isolation, supervision and other related areas [2  ###reference_b2###, 3  ###reference_b3###, 4  ###reference_b4###]. Nowadays, the widespread adoption of networked control systems and cyber-physical systems, coupled with the growing concerns regarding security threats and attacks, has led to increased interest and attention in control theory research [5  ###reference_b5###, 6  ###reference_b6###].\nIn recent years, there has been a significant focus on input and output selection problems [7  ###reference_b7###, 8  ###reference_b8###, 9  ###reference_b9###]. One prominent issue in this domain is sensor placement to guarantee state observability in the presence of unknown inputs, namely, state and input observability (SIO). In most cases, conditions for SIO and the associated observer design heavily relied on algebraic and geometric tools, with a primary emphasis on acquiring precise knowledge of the state matrices that characterize the system\u2019s model [10  ###reference_b10###, 11  ###reference_b11###]. However, in many modeling scenarios, obtaining accurate system parameters can be challenging, while obtaining the zero-nonzero structure is comparatively easier. Consequently, there has been a growing interest in studying system and control theory within structured system models, leveraging concepts from control theory and graph theory [12  ###reference_b12###, 13  ###reference_b13###]. Generic SIO (GSIO, also known as structural ISO [14  ###reference_b14###]) is the generic property corresponding to SIO studied in structured system models. GSIO implies that almost all numerical realizations of the structured system remain SIO. In recent years, sufficient and necessary conditions for GSIO have been proposed using the concepts, especially separators and vertex-disjoint edges, in directed graph (digraph) [8  ###reference_b8###, 15  ###reference_b15###, 16  ###reference_b16###].\nAdditionally, methods for sensor placement to recover GSIO based on Dulmage-Mendelsohn decomposition (DM-decomposition) have been developed, where sensors are not dedicated [17  ###reference_b17###]. Furthermore, many problems, like zero-dynamics attack, in cyber-physical systems and distributed systems also involve GSIO [18  ###reference_b18###, 19  ###reference_b19###, 20  ###reference_b20###].\nFrom a resource perspective, minimizing sensor resources to achieve system GSIO is crucial. However, many studies on the GSIO recovery problem primarily focus on utilizing undedicated sensors, that is, one sensor may measure a linear combination of an arbitrary set of state variables [8  ###reference_b8###], which could pose challenges in large-scale systems due to physical constraints such as geographic distance and communication capacity. Given this, the objective of this paper is to determine the minimum number of dedicated sensors (where each sensor measures only one state) required for a structured system to achieve GSIO. We call this the minimal GSIO problem. As it turns out that, this problem is equivalent to determining the sparsest output matrix (a.k.a., the minimum number of connectivity links between sensors and states) to achieve GSIO. In contrast to existing work [18  ###reference_b18###, 19  ###reference_b19###], we focus on structured systems with a fixed topology and without the self-loop constraint. Additionally, we enforce the dedicated constraint, whereas in [8  ###reference_b8###, 17  ###reference_b17###], sensors are non-dedicated. The contributions of this paper are summarized as follows:\nWe rectify certain inaccuracies in a prior proposition, which is crucial for achieving GSIO using dedicated sensors [17  ###reference_b17###].\nWe prove that the minimal GSIO problem is NP-hard. We further show that this problem is hard to approximate within a factor of , where  is the state dimension. This contrasts sharply with the polynomial-time complexity of the corresponding problem with known inputs, namely, the problem of determining the minimum number of dedicated sensors to achieve structural observability (called the minimal structural observability problem [21  ###reference_b21###]) .\nWe present an upper and a lower bound for the minimal GSIO problem when unknown inputs are dedicated, which can be computed in polynomial time. The given bounds confine the optimal value to an interval with length being the number of inputs. Central to deriving these bounds is establishing a connection between the minimal GSIO problem and the established minimal structural observability problem. We also present a special case for which the optimal value can be determined in polynomial time.\nWe propose a two-stage heuristic algorithm for the addressed problem. Each stage is designed to be either optimal or suboptimal and can be executed in polynomial time.\nGiven that GSIO characterizes the capability to observe both states and unknown inputs, it holds significant importance in the domain of systems security, especially in the context of zero-dynamics attacks, which refer to non-zero attacks that remain stealthy for all time from the moment of input [22  ###reference_b22###]. Our results emphasize the significance of sensor placement in ensuring the security of linear dynamic networks. They enable us to identify which set of states can be measured at a lower cost to effectively prevent zero-dynamics attacks.\nThe remainder of the paper is structured as follows: Section II  ###reference_### presents the problem formulation. Section III  ###reference_### provides necessary preliminaries. In Section IV  ###reference_###, we rectify certain inaccuracies in a prior proposition and propose the corrected one. Building on this, we prove the NP-hardness of the addressed problem. Section IV  ###reference_### concludes by proposing both upper and lower bounds, along with a specific polynomial case, and introducing a two-stage algorithm. Section V  ###reference_### offers illustrative examples. Finally, Section VI  ###reference_### presents the conclusion."

A structured matrix is defined as a matrix with entries that are either fixed to zero or represent free parameters that can take arbitrary values, including zero, with the flexibility for these parameters to vary independently.

A numerical system  is referred to as a realization of . We designate a property as generic for a structured system if it holds true for almost all of its realizations. Note that \u201cfor almost all of its realizations\u201d implies that the structured system can adopt all parameter values within the parameter space, except for some proper algebraic variety. For the matrix  associated with the structured system , the generic rank of  being , denoted as , implies that for almost all parameter values,  for all . Similarly, the generic rank of a structured matrix  is the rank of almost all of its realizations (which equals the maximum rank that realizations of  can take [25  ###reference_b25###, Props. 2.1.12 and 2.2.25]).\n[8  ###reference_b8###]\nThe system  is GSIO if almost all realizations of  are SIO.\nIn large-scale systems, physical constraints such as geographic distance and communication capacity often pose challenges for a single sensor to measure multiple states simultaneously. Hence, there arises a necessity to explore dedicated sensors for state measurements to solve minimal GSIO problem.

Therefore, the provided bounds greatly reduce the searching space for GSIO.\nInspired by Theorem 3  ###reference_orem3###, if sensors can be deployed to directly measure inputs, an analogous upper bound and lower bound is given by the following corollary, where both bounds are smaller than those in Theorem 3  ###reference_orem3###, and the length is also the number of inputs.\nFor a structured system  with  dedicated inputs, the optimal value of  is in the integer interval .\nThe lower bound  can be easily obtained due to conditions 1) and 2) of Lemma 7  ###reference_ma7###. For the upper bound, we construct a sensor placement where  sensors measure the  inputs respectively, and the other  sensors form any minimal senor placement for the minimal structural observability problem of . For this  sensor placement, 1) and 2) of Lemma 7  ###reference_ma7### hold. Moreover, since , we have . Thus, 3) of Lemma 7  ###reference_ma7### is satisfied. Consequently,  is the upper bound.\n\u220e\nThe difference between Theorem 3  ###reference_orem3### and Corollary 2  ###reference_ollary2### arises from the fact that prohibiting sensors from directly measuring unknown inputs requires that the state nodes belonging to  must match some input nodes, while this is not required when sensors can directly measure inputs. Based on Theorem 3  ###reference_orem3###, the crucial problem of determining sensor bounds lies in finding , which can be solved using various methods proposed in [21  ###reference_b21###, 9  ###reference_b9###]. Thus, the bounds can be computed in time  with  being the dimension of system.\nDespite  being NP-hard, Theorem 3  ###reference_orem3### provides an interval to search for the optimal solution of . Particularly, when the number of unknown inputs is small, this theorem can offer a relatively accurate sensor placement regardless of the size of system. However, when inputs are not dedicated, the minimum number of sensors does not meet the lower bound."

The difficulty stems from 3) of Lemma 7  ###reference_ma7###. More precisely, different  causes varying , as depicted in Fig. 4  ###reference_###, resulting in the same number of sensors leading to diverse GSIO properties of the system. This subsection discusses how we can efficiently solve  when every state vertex of the system digraph has a self-loop.\nConsider a structured system denoted as  with one dedicated input , where  (implying that every state vertex has a self-loop), and  represents the input matrix corresponding to the unique dedicated input . The digraph of  is denoted as . Let  be the auxiliary system of  defined in Subsection IV-C  ###reference_###, and  be the digraph of .

Denote  and  as the digraph of  and , respectively. Denote  as the number of input reachable sink-SCCs of , where an SCC is considered a sink-SCC if there are no outgoing edges from its vertices to other SCCs. Input-reachable means that there exists a path from an input  to states of this SCC. From the definition we have . Then, a lemma is proposed which is crucial for the sensor placement of this special case.\nGiven the system , the vertices set  in  remains constant across different minimum sensor placements  and  when .\nGiven that every state vertex has a self-loop in  and there is only one input vertex , only condition 2) of Lemma 6  ###reference_ma6### is required to achieve structural observability for . 2) of Lemma 6  ###reference_ma6### is equivalent to ensuring that each sink-SCC has at least one state vertex to be measured by sensors. Since ,  has  sink-SCCs, where . Let , denote the sets of state vertices for each sink-SCC. Then, for any minimum sensor placement  and ,  being structurally observable implies  in . This is because  has paths to  different sink-SCCs. Suppose  and  represent another minimum sensor placement such that  is structurally observable, we have  in . This equality arises because if we consider  as the subgraph of  obtained by removing any , there exists no path from  to any . Thus, there is also no path from  to any state vertex  in . Therefore, there is also no path from  to any  in , as  is the minimum sensor placement and solely measures states belonging to the sink-SCCs.

Then, if  fails to satisfy 3) of Lemma 7  ###reference_ma7###, according to the proof of Theorem 3  ###reference_orem3###, an additional sensor  is required. Therefore, Algorithm 1  ###reference_### is correct.\nNext, we analyze the complexity of Algorithm 1  ###reference_###. Step 1  ###reference_1### constructs the auxiliary system .

+    "abstract": "Recently, transformers have captured significant interest in the area of single-image super-resolution tasks, demonstrating substantial gains in performance. Current models heavily depend on the network\u2019s extensive ability to extract high-level semantic details from images while overlooking the effective utilization of multi-scale image details and intermediate information within the network. Furthermore, it has been observed that high-frequency areas in images present significant complexity for super-resolution compared to low-frequency areas. This work proposes a transformer-based super-resolution architecture called ML-CrAIST that addresses this gap by utilizing low-high frequency information in multiple scales. Unlike most of the previous work (either spatial or channel), we operate spatial and channel self-attention, which concurrently model pixel interaction from both spatial and channel dimensions, exploiting the inherent correlations across spatial and channel axis. Further, we devise a cross-attention block for super-resolution, which explores the correlations between low and high-frequency information. Quantitative and qualitative assessments indicate that our proposed ML-CrAIST surpasses state-of-the-art super-resolution methods (e.g., 0.15 dB gain @Manga109 4). Code is available on https://github.com/Alik033/ML-CrAIST.",

As an issue with inherent ambiguity and numerous possible solutions for a given LR image, several methods have emerged in recent years to address and overcome this challenge. Numerous methods in this context use convolution neural networks (CNNs) [9  ###reference_b9###, 10  ###reference_b10###, 15  ###reference_b15###, 32  ###reference_b32###, 35  ###reference_b35###, 47  ###reference_b47###] to improve performance in a variety of applications. These methods mostly use residual learning [15  ###reference_b15###], dense connections [35  ###reference_b35###], or channel attention [47  ###reference_b47###] to build network architectures, significantly contributing to developing super-resolution models. However, the CNN-based approach exhibits a limited receptive field due to the localized nature of convolution, which hampers the global dependencies, consequently restricting the overall performance of the model.\nIn recent times, the Transformer architecture, initially introduced in natural language processing (NLP), has demonstrated significant success across a wide range of high-level vision tasks [3  ###reference_b3###, 4  ###reference_b4###, 40  ###reference_b40###]. This success is attributed to its incorporation of a self-attention mechanism, which effectively establishes global dependencies. A notable advancement in SR is SwinIR [20  ###reference_b20###], which presents the Swin Transformer, leading to significant enhancements over state-of-the-art CNN-based models across different standard datasets. Subsequent developments, including Swin-FIR [43  ###reference_b43###], ELAN [45  ###reference_b45###], and HAT [6  ###reference_b6###], have extended the capabilities of SwinIR by utilizing Transformers to develop various network architectures for SR tasks. These methods demonstrate that appropriately enlarging the windows for the shifted window self-attention in SwinIR can lead to obvious improvements in performance. However, the increase in computational burden becomes a significant concern as the window size grows more prominent. Furthermore, Transformer-based methods rely on self-attention and need networks with more channels than previous CNN-based methods [1  ###reference_b1###, 14  ###reference_b14###, 16  ###reference_b16###]. Also, they use uni-dimensional aggregation operations (either spatial or channel) and homogeneous aggregation schemes (simple hierarchical stacking of convolution and self-attention). Wang et al. [37  ###reference_b37###] consider the above problem and design OmniSR to achieve superior performance. Despite substantial progress in super-resolution methods, they even encounter visual artifacts in the resulting images, such as inadequate texture representation and loss of details. Further, it has been observed that super-resolving high-frequency image areas are more challenging than low-frequency areas. Numerous existing SR methods work solely within the spatial domain, concentrating on improving the resolution of low-resolution pixels to obtain a high-resolution image. They often overlook the potential benefits of the frequency domain, which could offer a better method for retrieving lost high-frequency information. Also, it needs to include more texture patterns of multi-scales, which is required in SR tasks. Similar textures with multiple scales may exist within a single image at different positions. For instance, repetitive patterns at different scales (such as facades, windows, etc., in a building) may appear in various locations within a single image. The multi-scale aware framework is required to use the beneficial non-local detail, which aggregates the information from all the different scales of the LR image.\nTo address the above mentioned issues and achieve higher performance, this work proposes a novel super-resolution model that simultaneously exploits frequency and spatial domain information at different scales. 2D Discrete Wavelet Transformation (2dDWT) is used to analyze both the high (LH, HL, and HH) and low (LL) frequency wavelet sub-bands. To carefully design a cross-attention block, we fuse low and high frequency information to boost SR performance. We explore the features in multiple scales and systematically combine information across all scales at each resolution level, facilitating meaningful information exchange. Simultaneously, another fusion technique is proposed to combine the high-frequency sub-bands while maintaining their unique complementary characteristics that differ from simple concatenation or averaging of the sub-bands. The major contributions of this paper are as follows:\nA novel multi-scale model is proposed by utilizing both spatial and frequency domain features that is capable to enhance the spatial resolution of an low-resolution image.\nIn addition, a low-high frequency interaction block (LHFIB) is introduced to exchange the information between low and high frequency sub-bands through the proposed cross attention block (CAB).\nA non-linear approach is proposed to fuse high-frequency sub-bands using an attention mechanism for more precise restoration of high-frequency details.\nInformative features are obtained from different scales using CAB while preserving the high-resolution features to represent spatial details accurately."

SRCNN [10  ###reference_b10###] is notable as the pioneering CNN-based super-resolution method, outperforming the performance of traditional approaches (e.g., bicubic, nearest-neighbor, and bilinear interpolation). After this initial advancement, significant attention has been directed towards expanding the network depth and incorporating residual learning techniques to enhance super-resolution performance [15  ###reference_b15###, 35  ###reference_b35###, 47  ###reference_b47###]. EDSR [21  ###reference_b21###] further improves peak signal-to-noise ratio (PSNR) results significantly by removing the unnecessary Batch Normalization layers. Additionally, RCAN [47  ###reference_b47###] integrates a channel attention mechanism to enhance feature aggregation efficiency, enabling improved performance even with deeper network architectures. Subsequent models such as SAN [9  ###reference_b9###], NLSA [28  ###reference_b28###], and HAN [29  ###reference_b29###] have introduced a range of attention mechanisms, either focusing on spatial or channel dimensions, reflecting a growing trend in attention-based approaches within the field. To improve reconstruction quality while working within constrained computing resources, DRCN [16  ###reference_b16###], DRRN [34  ###reference_b34###], CARN [1  ###reference_b1###], IMDN [14  ###reference_b14###] delve into lightweight architectural designs. Another research direction is operating model compression strategies like knowledge distillation [11  ###reference_b11###, 46  ###reference_b46###] and neural architecture search [8  ###reference_b8###] to decrease computing costs.\nGenerative adversarial networks (GANs) for SR. GANs [12  ###reference_b12###] provide a fundamental method to balance perception and distortion by regulating the weights of perceptual and fidelity losses, generating realistic images. [18  ###reference_b18###] introduced SRGAN, which incorporates adversarial training with the SRResNet generator. [38  ###reference_b38###] presented ESRGAN featuring the residual-in-residual dense block framework for super-resolution. Later, [33  ###reference_b33###] enhanced ESRGAN by auxiliary noise injection and proposed ESRGAN+. Park et al. [31  ###reference_b31###] suggested Flexible Style SR, which optimizes the SR model with image specific objectives without viewing the regional features. These methods [18  ###reference_b18###, 30  ###reference_b30###, 33  ###reference_b33###, 38  ###reference_b38###] suffer from the computational burden posed by numerous image maps.\nTransformer-based methods for SR. Recently, Transformers have shown significant promise in a range of vision tasks, including image classification [40  ###reference_b40###], object detection [4  ###reference_b4###], semantic segmentation [3  ###reference_b3###], image restoration [5  ###reference_b5###, 22  ###reference_b22###, 39  ###reference_b39###], etc. Among these approaches, the most prominent example is the Vision Transformer (ViT), demonstrating that transformers can outperform convolutional neural networks in feature encoding tasks. Designing transformer-based models for image super-resolution poses a significant challenge as it requires preserving the structural details of the input image. IPT [5  ###reference_b5###] is a pre-trained model built upon the transformer encoder and decoder structure and has been used for super-resolution. SwinIR [20  ###reference_b20###] employs a window-based attention mechanism to tackle image super-resolution tasks, demonstrating superior performance over CNN-based methods. ELAN [45  ###reference_b45###] facilitates the architecture of SwinIR and utilizes self-attention calculated in different window sizes to capture correlations between long-range pixels. Choi et al. [7  ###reference_b7###] introduce N-gram context into low-level vision tasks using Transformers for the SR task. Most recently, OmniSR [37  ###reference_b37###] explored spatial-channel axis aggregation networks to enhance SR performance.\nOur approach also relies on the transformer architecture. Unlike the aforementioned methods, which predominantly utilize spatial domain information and compute self-attention for model construction, our primary focus is on leveraging spatial-frequency domain features and multi-scale features through cross-attention to improve the performance of the super-resolution model.\n###figure_1###"

+    "abstract": "Understanding human attention is crucial for vision science and AI. While many models exist for free-viewing, less is known about task-driven image exploration. To address this, we introduce CapMIT1003, a dataset with captions and click-contingent image explorations, to study human attention during the captioning task. We also present NevaClip, a zero-shot method for predicting visual scanpaths by combining CLIP models with NeVA algorithms. NevaClip generates fixations to align the representations of foveated visual stimuli and captions. The simulated scanpaths outperform existing human attention models in plausibility for captioning and free-viewing tasks. This research enhances the understanding of human attention and advances scanpath prediction models.",

Visual attention is an essential cognitive process in human beings, enabling selective processing of relevant portions of visual input while disregarding irrelevant information [10  ###reference_b10###, 14  ###reference_b14###]. Models of human attention are of great interest in neuroscience and applications [5  ###reference_b5###], particularly for the case of scanpath prediction as it provides a more detailed understanding of visual attention dynamics compared to saliency prediction[1  ###reference_b1###, 2  ###reference_b2###]. Seminal work [4  ###reference_b4###, 18  ###reference_b18###] investigated the relationship between eye movement patterns and high-level cognitive factors to demonstrate the influential role of task demands on eye movements and visual attention. Despite great interest in understanding mechanisms underlying task-driven visual exploration, most current classical [7  ###reference_b7###, 3  ###reference_b3###, 13  ###reference_b13###, 20  ###reference_b20###] or machine learning-based [15  ###reference_b15###, 19  ###reference_b19###, 12  ###reference_b12###] computational models focus on free viewing, which primarily involves bottom-up saliency, and overlooks the influence of different tasks. \nContributions.\nTo investigate task-driven human attention and its interplays with language, we propose computational models that simulate human attention scanpaths during the captioning process.\nFirst, we use a web application the expand the well-known MIT1003 dataset [9  ###reference_b9###] with click-contingent task-driven image exploration. We call the new dataset CapMIT1003 and release it publicly.\nSecond, we combine Neural Visual Attention [17  ###reference_b17###] algorithms with Contrastive Language-Image Pretrained (CLIP) [16  ###reference_b16###] models, to generate task-driven scanpaths under human-inspired constraints of foveated vision.\nWe found that generating scanpaths conditioned on the correctly associated captions results in highly plausible scanpath trajectories that achieve state-of-the-art results for the newly collected dataset."

We instructed users to describe the content of the image with \"one or two sentences\", in English. All clicks and captions are stored in a database, while no personal information has been collected. In total, we collected 27865 clicks on 4573 observations over 153 sessions. We excluded 654 observations that were skipped, 33 with no recorded clicks, and 38 captions with less than 3 characters.

Code is made publicly available 222https://github.com/dario-zanca/NevaClip  ###reference_###. We use the implementation of the CLIP model provided by the original authors333https://github.com/openai/CLIP  ###reference_github.com/openai/CLIP###. Unless stated otherwise, all NevaClip results are presented for the Resnet50 backbone. For all competitor models, the original code provided by the authors is used.\nBaselines and models. We evaluate three distinct variations of our NevaClip algorithm. For NevaClip (correct cap.), scanpaths are generated maximizing the alignment between visual embeddings of the foveated stimuli, and text embeddings of the corresponding captions. For NevaClip (different caption, same image) , scanpath are generated to maximize the alignment between visual embeddings of the foveated stimuli, and text embeddings of the captions provided by a different subject on the same image. For NevaClip (different caption, different image), scanpath are generated to maximize the alignment between visual embeddings of the foveated stimuli, and text embeddings of the random captions provided by a different subject on a different image.\nWe include two baselines, i.e., Random and Center [9  ###reference_b9###], to better position the quality of the results. We include also four competitor models [17  ###reference_b17###, 3  ###reference_b3###, 20  ###reference_b20###, 11  ###reference_b11###].\nScanpath similarity.\nTo measure the similarity between simulated and human scanpaths, we compute ScanPath Plausibility (SPP) [6  ###reference_b6###], using the string-based time-delay embeddings (SBTDE) [17  ###reference_b17###] as a basic metric. In table 1  ###reference_### we summarise the SPP SBTDE scores for all baselines, competitors, and NevaCLIP versions. The scores are computed for each sublength , and the average of mean and standard deviation for all sublengths is presented.\nFor CapMIT1003 (captioning task), NevaClip (correct caption) outperforms all other approaches. As expected, NevaClip (different subject, different image), which generates a scanpath using a label from a different image and a different subject, performs similarly to the Random Baseline. The NevaClip (correct caption) performs slightly better than the NevaClip (different subject, same image), demonstrating that the caption provided by the subject brings useful information about their own visual exploration behavior. Among competitors, G-Eymol and Neva (original) compete well, despite not incorporating any caption information. It is worth noting that all approaches do not use any human gaze data for training, and the scanpath prediction is performed zero-shot.\nIn MIT1003 (free-viewing), NevaClip (correct caption) and NevaClip (different subject, same image) also perform better than state-of-the-art models,\nthus proving a substantial overlap between the two tasks."

This is reflected in the results, where all approaches achieve lower performance in terms of scanpath plausibility (see table 1  ###reference_###) for the captioning task. The ranking of models remains consistent across both tasks, with free-viewing models performing reasonably well on both datasets. This observation suggests a substantial overlap between free viewing and captioning, possibly due to the initial phases of exploration being predominantly driven by bottom-up factors rather than task-specific demands.\nA possible limitation of our work is represented by the click-contingent data collection. Future studies may complement this data collection with actual gaze data and explore differences between the two modalities."

+    "abstract": "The imbalance of exploration and exploitation has long been a significant challenge in reinforcement learning. In policy optimization, excessive reliance on exploration reduces learning efficiency, while over-dependence on exploitation might trap agents in local optima. This paper revisits the exploration-exploitation dilemma from the perspective of entropy by revealing the relationship between entropy and the dynamic adaptive process of exploration and exploitation. Based on this theoretical insight, we establish an end-to-end adaptive framework called AdaZero, which automatically determines whether to explore or to exploit as well as their balance of strength.\nExperiments show that AdaZero significantly outperforms baseline models across various Atari and MuJoCo environments with only a single setting. Especially in the challenging environment of Montezuma, AdaZero boosts the final returns by up to fifteen times. Moreover, we conduct a series of visualization analyses to reveal the dynamics of our self-adaptive mechanism, demonstrating how entropy reflects and changes with respect to the agent\u2019s performance and adaptive process.",

+            "text": "In reinforcement learning (RL), the objective of policy optimization is to directly optimize a policy\u2019s parameters by maximizing the cumulative rewards (Ahmed et al. 2019  ###reference_b1###; Schulman et al. 2015  ###reference_b34###, 2017  ###reference_b35###; Bellemare et al. 2016a  ###reference_b5###). Due to the sparsity and delay of rewards (Hao et al. 2023  ###reference_b16###; Kang et al. 2021  ###reference_b18###), the policy optimization process is usually ineffective and hindered. To tackle this challenge, methods are proposed to improve exploration or exploitation respectively.\nOn the one hand, exploration-centric methods enhance the formation of new policies by expanding the search range of actions and/or states. For example, methods based on maximum entropy (Ahmed et al. 2019  ###reference_b1###; Haarnoja et al. 2018  ###reference_b14###; Zhang et al. 2024  ###reference_b41###; Han and Sung 2021  ###reference_b15###) encourages exploration by increasing randomness, and intrinsic reward methods (Schmidhuber 2010  ###reference_b33###; Kim et al. 2019  ###reference_b19###; Ermolov and Sebe 2020  ###reference_b11###; Bougie and Ichise 2020  ###reference_b7###; Mu et al. 2022  ###reference_b25###; Henaff et al. 2022  ###reference_b17###; Mutti, De Santi, and Restelli 2022  ###reference_b26###) leverage state coverage to drive exploration. On the other hand, exploitation-centric methods (Oh et al. 2018  ###reference_b27###; Schulman et al. 2017  ###reference_b35###) execute the currently optimal policy based on the experience already learned by the agent, aiming to straightforwardly obtain the maximum cumulative returns.\nWhile the exploration-centric and exploitation-centric methods both have made some progress, previous works pay less attention to the synergy of exploration and exploitation, which is crucial for policy optimization.\nBalancing exploration and exploitation presents a complex dilemma in practice. Agents must consider multiple factors, including the environment\u2019s dynamism, local optima traps, and reward delays. Balancing short-term returns with long-term gains within limited time and resources is exceedingly challenging.\nAn ideal policy optimization process is expected to effectively switch between exploration and exploitation policies and adaptively balance the two effects.\nA few attempts have been made to address the imbalance problem of exploration and exploitation, including decaying intrinsic reward after a certain number of steps (Badia et al. 2020  ###reference_b3###; Yan et al. 2023  ###reference_b40###), and decoupling the training of exploration and exploitation policy (Liu et al. 2021  ###reference_b21###; Colas, Sigaud, and Oudeyer 2018  ###reference_b10###). Essentially, these methods are still exploration-centric, since the intrinsic rewards will never diminish to zero. In fact, as the extrinsic rewards are sparse, the non-zero intrinsic rewards, no longer how small, will dominate the training process at most of the time. Simply weakening the strength of exploration in a rigid manner will result in a sub-optimal policy.\nIn this paper, we revisit the exploration-exploitation dilemma from an entropy perspective. We start by theoretically revealing the relationship between entropy and intrinsic rewards in policy optimization, showing them changing synchronously in certain conditions.\nFrom this viewpoint, we can treat the increase and decrease of entropy as proxies to indicate the agent\u2019s ability of exploration and exploitation in the current environment. We argue the presence and amount of intrinsic rewards should be determined by the agent\u2019s level of mastery about the environment. Hence, we formulate a dynamic adaptive process of policy optimization and derive several representative scenarios characterizing its self-adaptive capability of exploration and exploitation.\nBased on these theoretical insights, we establish an end-to-end adaptive framework AdaZero. AdaZero continues to evaluate the agent\u2019s mastery level in each state via an evaluation network and adaptively determines the balance of strength of exploration and exploitation.\nThe state autoencoder receives real-time state images and outputs the reconstruction error as intrinsic rewards to encourage exploration. Meanwhile, the reconstructed state image generated by the autoencoder, which represents the agent\u2019s mastery level of the current state, is provided to an evaluation network to determine the strength of exploration and exploitation.\nGuided by this mechanism, agents can automatically adapt to environmental changes and decide whether to explore or to exploit, as well as the strength of both, thus breaking out from the dilemma of imbalanced exploration-exploitation.\nThe adaptive mechanism of AdaZero is entirely realized in an end-to-end manner without any need to manually design a decaying scheme.\nTo provide empirical support for our theoretical findings and to validate the effectiveness of our proposed self-adaptive mechanism, we experiment with AdaZero on 63 Atari and\nMuJoCo tasks with continuous and discrete action state spaces. The results show that without any customized reward design or tuning of hyperparameters for each environment, AdaZero outperforms previous methods by a large margin across simple to difficult environments, demonstrating the superiority of our self-adaptive mechanism. We also perform a series of visualization analyses to reveal the functionality of entropy in policy optimization and how AdaZero\u2019s automatic adaptive exploration and exploitation effectively works.\n###figure_1###"

(4  ###reference_###), we have\nDepending on the mastery level of the states , there will be different scenarios regarding the relationship between exploration and exploitation.

In this scenario, the strength of exploration reaches the peak level, which means our method exhibits stronger exploratory capabilities than methods without intrinsic rewards.\nCase II - Adaptive Exploration-Exploitation:  satisfies  and . This means , i.e., the probability of optimal policy increases while entropy starts to decrease. In this scenario, the degree of exploitation adaptively increases while the level of exploration decreases.\nCase III - Exploitation Dominant: for any , when , we have , and .

This implies that our method can conduct a certain level of exploration while leveraging existing experience, compared with traditional RL methods like PPO (Schulman et al. 2017  ###reference_b35###; Mnih et al. 2015  ###reference_b23###). Besides, in contrast to existing exploration-centric methods based on intrinsic rewards or maximum entropy, our method can alternate between exploration and exploitation adaptively.\nThis theoretical advantage of our method will be further confirmed in our visualization experiment (Figure 5  ###reference_### and Section 5.1  ###reference_###)."

As illustrated in Figure 1  ###reference_###, the AdaZero framework consists of three parts: a state autoencoder, a mastery evaluation network and the policy optimization mechanism (referred to as the adaptive mechanism).\nThe state autoencoder aims to motivate the agent\u2019s exploratory behavior of searching for unknown policies to get familiar with the environment. As shown in Figure 1  ###reference_### (A), the state autoencoder receives raw states  via the interaction between the agent and the environment and learns to reconstruct the input images , where  is network parameters. The reconstruction error  is defined as follows:\nWe use the reconstruction error as intrinsic rewards to drive exploration.\nA larger error indicates insufficient training of the network on the state, and hence enhanced exploration is needed for this state. Oppositely, a smaller error indicates that the training on that state has been sufficient, leading to an automatic decrease of intrinsic reward.\nNote that we only need a single network to estimate intrinsic rewards in contrast to competitive methods like RND and NGU. Moreover, our state autoencoder operates on raw images rather than latent representations of states, leading to a more accurate measurement of state novelty.\n###figure_3### While conducting effective exploration is essential in environments with sparse rewards and delayed feedback, solely focusing on exploration without exploitation can potentially reducing learning efficiency as the agent may spend excessive time exploring ultimately ineffective policies. Therefore, correctly determining where and how much to explore based on the agent\u2019s mastery level of the states is crucial for the agent\u2019s performance. To this end, AdaZero involves a mastery evaluation network to provide real-time assessment of the necessity of exploration, as shown in Figure 1  ###reference_### (B).\nThe mastery network is a binary classifier denoted as . At the training stage, the network receives mixed data of real state images and fake state images reconstructed by the state autoencoder, denoted as  and  respectively. It is trained to distinguish between the two kinds of inputs and output the probability of the inputs being real images, with a cross-entropy loss defined as follows:\nwhere  is the network\u2019s parameters,  and  are the set of real state images and reconstructed images respectively.\nAt the inference stage, the evaluation network only receives the reconstructed images from the state autoencoder and outputs the probability . Hence,  can naturally serve as a measure of AdaZero\u2019s grasp of the current training state information.\nInspired by Eqn. 4  ###reference_### and Theorem 1  ###reference_1###, By integrating the reconstruction error  provided by the state autoencoder and the estimated level of mastery of the state information  from the evaluation network, we implement the adaptive mechanism of AdaZero depicted in Figure 1  ###reference_### (C) through the following formula:\nWhen the agent reaches a high level of mastery in current state, the exploration intensity should be reduced to increase the exploitation ratio. Conversely, when the level of mastery is low, the exploration intensity should be increased to encourage the agent to better learn from the various information about the state. As  reflects the agent\u2019s ability to grasp valuable information in the reconstructed states, we leverage  to adaptively control the strength of intrinsic rewards, and hence dynamically balance the exploration and exploitation.\nNote that compared with methods that simply decays intrinsic rewards (Badia et al. 2020  ###reference_b3###; Yan et al. 2023  ###reference_b40###), the adaptive mechanism of AdaZero is entirely realized by end-to-end networks without any need to manually design a decaying scheme. It can adaptively increase or decrease intrinsic rewards according to the training progress and environment changes."

Moreover, it can be observed that there are more horizontal fluctuations in curves of the methods integrated with AdaZero.

The agent starts at point s in the top-right corner, explores the environment to avoid wall obstacles, and eventually reaches the point in the bottom-left corner to obtain a reward. As shown in Figure 7  ###reference_###, AdaZero achieves the largest exploration area, nearly completing a full exploration of the environment and establishing a stable shortest-path strategy. The direction indicated by the arrows shows that our method forms the shortest path, demonstrating AdaZero\u2019s superior exploration ability. In contrast, the ablation version, AdaZero without adaptive, though performing better than the baseline, has a smaller exploration area and a less prominent shortest path than AdaZero, highlighting the importance of AdaZero\u2019s adaptive mechanism."

Researchers have explored various methods to address this issue, with intrinsic rewards(Burda et al. 2019  ###reference_b9###) and maximum entropy approaches(Mutti, De Santi, and Restelli 2022  ###reference_b26###) being among the most effective. The former encourages agents to discover novel states by measuring novelty through state visit density, while the latter enhances exploration quality by promoting randomness in policies. Despite progress, these methods still struggle with adaptive coordination between exploration and exploitation.\nA few studies have attempted to address this challenge. For instance, intrinsic reward methods(Badia et al. 2020  ###reference_b3###) with decay factors introduce an annealing-like mechanism into the reward function, and approaches like decoupled reinforcement learning(Sch\u00e4fer et al. 2021  ###reference_b32###) separately optimize exploration and exploitation strategies. However, these methods fail to achieve a truly adaptive balance between exploration and exploitation. The primary limitation is that the intrinsic motivation terms cannot fully adaptively decay to zero based on the environment and training progress; instead, they gradually reduce to zero. Moreover, these methods rely on manually designed decay coefficients or strategy separation and merging based on human experience.\nFor a detailed discussion of related literature, refer to Appendix A for additional related works."

Based on this motivation, we re-examined the exploration-exploitation dilemma from the perspective of entropy and proposed an adaptive exploration-exploitation mechanism. Inspired by this mechanism, we formalized the AdaZero which achieves adaptation based on end-to-end networks. and conducted extensive experiments in up to 65 environments. Both theoretical analysis and experimental results demonstrate that, compared to traditional RL algorithms, our method enables selective exploration while exploiting. Compared to exploration-dominant algorithms, our method allows for selective exploitation while exploring."

+    "title": "Parseval Convolution Operators and Neural Networks",
+    "abstract": "We first establish a kernel theorem that characterizes all linear shift-invariant (LSI) operators acting on discrete multicomponent signals. This result naturally leads to the identification of the Parseval convolution operators as the class of energy-preserving filterbanks. We then present a constructive approach for the design/specification of such filterbanks via the chaining of elementary Parseval modules, each of which being parameterized by an orthogonal matrix or a 1-tight frame. Our analysis is complemented with explicit formulas for the Lipschitz constant of all the components of a convolutional neural network (CNN), which gives us a handle on their stability. Finally, we demonstrate the usage of those tools with the design of a CNN-based algorithm for the iterative reconstruction of biomedical images. Our algorithm falls within the plug-and-play framework for the resolution of inverse problems. It yields better-quality results than the sparsity-based methods used in compressed sensing, while offering essentially the same convergence and robustness guarantees.",

+    "abstract": "Transformer-based recommender systems, such as BERT4Rec or SASRec, achieve state-of-the-art results in sequential recommendation. However, it is challenging to use these models in production environments with catalogues of millions of items: scaling Transformers beyond a few thousand items is problematic for several reasons, including high model memory consumption and slow inference. In this respect, RecJPQ is a state-of-the-art method of reducing the models\u2019 memory consumption; RecJPQ compresses item catalogues by decomposing item IDs into a small number of shared sub-item IDs. Despite reporting the reduction of memory consumption by a factor of up to , the original RecJPQ paper did not report inference efficiency improvements over the baseline Transformer-based models.\nUpon analysing RecJPQ\u2019s scoring algorithm, we find that its efficiency is limited by its use of score accumulators for each item, which prevents parallelisation. In contrast, LightRec (a non-sequential method that uses a similar idea of sub-ids) reported large inference efficiency improvements using an algorithm we call PQTopK. We show that it is also possible to improve RecJPQ-based models\u2019 inference efficiency using the PQTopK algorithm.  In particular, we speed up RecJPQ-enhanced SASRec by a factor of 4.5 compared to the original SASRec\u2019s inference method and by the factor of 1.56 compared to the method implemented in RecJPQ code on a large-scale Gowalla dataset with more than million items. Further, using simulated data, we show that PQTopK remains efficient with catalogues of up to tens of millions of items, removing one of the last obstacles to using Transformer-based models in production environments with large catalogues.",

+            "text": "The goal of sequential recommender models is to predict the next item in a sequence of user-item interactions. The best models for this task, such as SASRec (Kang and McAuley, 2018  ###reference_b10###) and BERT4Rec (Sun et al., 2019  ###reference_b18###), are based on adaptations of the Transformer (Vaswani et al., 2017  ###reference_b21###) architecture.\nIndeed, while the Transformer architecture was originally developed for natural language processing, sequential recommender systems adapt the architecture by using tokens to represent items, and the next item prediction task then becomes equivalent to the next token prediction task in the language models.\nDespite achieving state-of-the-art results on datasets available in academia, it is challenging to use these models in a production environment due to the scalability issues: the number of items in large-scale recommender systems, such as product recommendations in Amazon, can reach hundreds of millions (Ama, 2023  ###reference_b2###), which is much larger than tens of thousands of tokens in the dictionaries of language models. A large catalogue causes several problems in Transformer models, such as large GPU memory requirements to store the item embeddings during training, large computational resources required to train models, and slow inference in production. Several works have recently addressed the memory consumption issues (Xia et al., 2023  ###reference_b22###; Petrov and Macdonald, 2024  ###reference_b17###) and inefficient training (Klenitskiy and Vasilev, 2023  ###reference_b11###; Petrov and Macdonald, 2023  ###reference_b16###, 2025  ###reference_b14###); however, efficient model inference remains an open question, which is the focus of this paper.\nEfficient inference is especially important when considering a model deployment on CPU-only hardware (i.e. without GPU acceleration). Indeed, deploying a trained model on CPU-only hardware is often a practical choice, considering the high running costs associated with GPU accelerators.\nHence, in this paper, we specifically focus on the CPU-only inference efficiency of Transformer-based sequential recommendation models.\n###figure_1### The inference of a Transformer-based recommendation model consists of two parts: computing a em sequence representation using the backbone Transformer model, followed by computing the scores of individual items using this representation (see Section 2  ###reference_### for details). The main cause of the slow inference by Transformer-based models arises not from the Transformer backbone model itself but from the computation of all the item scores. Indeed, the inference time of a given Transformer backbone model is constant w.r.t. the number of items (after embedding lookup, which is  operation, the Transformer model only works with embeddings, which do not depend on the number of items); however, computing item scores has a linear complexity w.r.t. the number of items. Hence, to speed up inference, there are three options: (i) reduce the number of scored items, (ii) reduce the number of operations per item, and (iii) efficiently parallelise computations.\nIn the first category are the approximate nearest neighbour methods, such as FAISS (Johnson et al., 2021  ###reference_b9###) or Annoy (Spo, 2024  ###reference_b3###). While these methods can be practical in some cases, there are two problems: (i) these methods are unsafe (Turtle and Flood, 1995  ###reference_b20###; Tonellotto et al., 2018  ###reference_b19###), meaning that the results retrieved using an ANN index may omit some candidates that would have been scored high by the model and (ii) they require item embeddings to be present in the first place in order to build the index, and training item embeddings for all items in large catalogue case may not be feasible in the first place (Petrov and Macdonald, 2024  ###reference_b17###).\nTherefore, this paper focuses on analysing the efficiency of existing methods and reducing the number of operations per item and parallelising the computations. In particular, we build upon RecJPQ (Petrov and Macdonald, 2024  ###reference_b17###), a recent state-of-the-art approach for compressing embedding tables in Transformer-based sequential recommenders. RecJPQ achieves compression by representing items using a concatenation of shared sub-ids. While achieving great results on compression (for example, on the Gowalla (Cho et al., 2011  ###reference_b6###) dataset, RecJPQ achieves up to 50 compression without degrading effectiveness), the RecJPQ paper does not perform any analysis of the model\u2019s inference in large catalogues and only briefly mentions that it is similar to the inference time of the original non-compressed models. On the other hand, prior works that built upon similar ideas of sub-id-based recommendation, such as LightRec (Lian et al., 2020  ###reference_b12###), showed that the sub-id-based method could indeed improve model inference time. Inspired by LightRec, we describe a sub-id-based scoring algorithm for PQ-based models, which we call PQTopK. We further analyse if RecJPQ-enhanced Transformer-based recommendation models can be efficiently inferred on catalogues with (multiple) millions of items using the PQTopK algorithm in a CPU-only environment.\nThe main contributions of this paper can be summarised as follows: (i) we analyse inference efficiency of RecJPQ-enhanced versions of SASRec (Kang and McAuley, 2018  ###reference_b10###) and BERT4Rec (Sun et al., 2019  ###reference_b18###) and find that it is more efficient than Matrix-Multiplication based scoring used in the original models; (ii) we show that scoring efficiency of RecJPQ-based models can be improved using the PQTopK algorithm (iii) we explore the limits of PQTopK-based inference using simulated settings with up to 1 billion items in catalogue and show that inference remains efficient with millions of items.\nTo the best of our knowledge, this is the first analysis of the inference of sub-id-based sequential models on large-scale datasets and the first demonstration of the feasibility of using these models in the large-catalogue scenario."

While versions of this algorithm have previously been described, for example, for a different recommendation scenario (Lian et al., 2020  ###reference_b12###) and for document retrieval (Zhan et al., 2021  ###reference_b23###), to the best of our knowledge, it has not been previously applied for sequential recommendation nor Transformer-based models.\nPQTopK first splits the sequence embedding  obtained from a Transformer model into  sub-embeddings , with  for , such that .\nBy substituting Equation (2  ###reference_###) and the similarly decomposed sequence embedding  into Equation (3  ###reference_###), the final item score for item  is obtained as the sum of sub-embedding dot-products:\nLet  denote the sub-id score matrix, which consists of sub-id scores , defined as dot products of the sub-item embedding  and the sequence sub-embeddings :\nThe final score of item  can, therefore, also be computed as the sum of the scores of its associated sub-ids:\nFigure 1  ###reference_### also graphically illustrates how item scores are computed using PQ.\nThe number of splits  and the number of sub-ids per split  are usually chosen to be relatively small,\nso that the total number of sub-id scores is much less compared to the size of the catalogue, e.g., .\nTherefore, this allows to compute the matrix  only once for a given sequence embedding and then reuse these scores for all items. This leads to efficiency gains compared to matrix multiplication, as scoring each item now only requires  additions instead of  multiplications and  additions per item. The time for pre-computing sub-item scores does not depend on  and\nwe can assume that it is negligible w.r.t. the exhaustive scoring of all items.\nAlgorithm 1  ###reference_### illustrates the PQTopK in pseudo-code. Note that the algorithm has two loops: the outer loop (line 6  ###reference_6###) iterates over the items in the catalogue, and the inner loop (line 7  ###reference_7###) iterates over codes associated with the item. However, as the item scores are independent of each other, both loops can be efficiently parallelised222We achieve parallelisation using Tensorflow accelerated computation framework..\nThe original RecJPQ (Petrov and Macdonald, 2024  ###reference_b17###) code is also based on the same idea of pre-computing item scores and then computing item scores as the sum of associated sub-id scores. However, in RecJPQ, the order of loops is swapped compared to the PQTopK algorithm: the outer loop iterates over the splits, and in the inner loop, the scores for each item are accumulated for each item (we list RecJPQ\u2019s original scoring algorithm in Algorithm 2  ###reference_###). Due to the iterative accumulation of item scores, the outer loop in RecJPQ\u2019s scoring algorithm is not parallelised. In Section 5  ###reference_###, we show that this makes RecJPQ\u2019s scoring algorithm less efficient compared to PQTopK."

We experiment with two real-world datasets: Booking.com (Goldenberg and Levin, 2021  ###reference_b7###) (35K items) and Gowalla (Cho et al., 2011  ###reference_b6###) (1.3M items). Following common practice, we remove users with less than five items from the data. Salient characteristics of the experimental data are provided in Table 1  ###reference_###. Additionally, to test the inference speed of different scoring methods, we use simulated data with up to 1 billion items in the catalogue.\nBackbone Models. In RQ1,  we experiment with two commonly used Transformer models: SASRec and BERT4Rec. To be able to train the models on large catalogues, we replace the item embedding layer with RecJPQ (Petrov and Macdonald, 2024  ###reference_b17###). Moreover, the original BERT4Rec does not use negative sampling, which makes it infeasible to train on large catalogues, such as Gowalla. Hence, to be able to deal with large catalogues, we use gBERT4Rec (Petrov and Macdonald, 2023  ###reference_b16###), a version of BERT4Rec trained with negative sampling and gBCE loss. The configuration of the models follows the details described in the RecJPQ paper (Petrov and Macdonald, 2024  ###reference_b17###). In particular, we use 512-dimensional embeddings; we use 2 Transformer blocks for SASRec and 3 Transformer blocks for BERT4Rec. When answering RQ1, we use RecJPQ with  splits but vary  in RQ2. In RQ2, we exclude the backbone model from our analysis; therefore, the results are model-agnostic and apply to any backbone.\nScoring Methods. We analyse three scoring methods: (i) Transformer Default, matrix multiplication-based scoring  used by default in SASRec and BERT4Rec (w/o any PQ enhancements); (ii) the original RecJPQ scoring (Algorithm 2  ###reference_###); (iv) PQTopK scoring (Algorithm 1  ###reference_###).

Our main focus is on the model inference speed. We measure inference using the median response time per user (mRT, time required by the model to return recommendations). We do not use GPU acceleration when measuring any response time (details of our hardware configuration are in Table 2  ###reference_###). We separately measure total response time, time spent by the model for running the backbone Transformer model, and time spent by the scoring algorithm. For completeness, we also report effectiveness using NDCG@10, even though optimising model effectiveness is outside of the scope of the paper and all scoring methods for RecJPQ-based models have the same effectiveness."

Table 3  ###reference_### reports effectiveness and efficiency metrics for SASRec and BERT4Rec on both Booking.com and Gowalla datasets. We first observe that nDCG@10 values do not depend on the scoring method, as all algorithms compute the same score distribution. We also see that the model backbone model inference time does not depend on the scoring method as well, as different scoring methods are applied on top of the backbone Transformer model (i.e. we use different \u201cheads\u201d in Transformer terminology). Interestingly, the time required by the backbone Transformer model does not depend on the dataset either: e.g., BERT4Rec requires roughly 37 milliseconds on both Booking and Gowalla, while SASRec requires roughly 24 milliseconds. This makes sense as Transformer complexity depends on the embedding dimensionality, the number of Transformer blocks and the sequence length but not on the number of items in the catalogue.\nOn the smaller Booking.com dataset, we see that the running time of the backbone Transformer model dominates the total model response time, and the differences between different scoring methods are rather unimportant. For example, when using gBERT4Rec on this dataset, the slowest scoring method (Transformer Default) requires 43 milliseconds per user. In contrast, the faster method (PQTopK) requires 40 milliseconds (\u00a110%) \u2013 even though PQTopK is two times faster compared to Transformer Default scoring when comparing without the backbone model inference. In contrast, on the larger Gowalla dataset with more than 1M items, there is a large difference between different scoring methods. For example, when using Default Transformer scoring with SASRec, inference time is dominated by the item scoring (131ms out of 171ms).\n###table_1### When using SASRec as the backbone with RecJPQ scoring, both the backbone and the scoring head contribute similarly towards total scoring time (SASRec takes 24ms while scoring takes 29ms). In contrast, when using PQTopK, the total time is dominated by the Transformer model itself (e.g., PQTopK only uses 10ms. out of 34 when using the SASRec backbone). If we isolate scoring time, the Gowalla with SASRec backbone dataset with PQTopK is 13 faster than the Transformer default and  faster than RecJPQ scoring.\nIn summary, answering RQ1, we find that PQTopK is the most efficient method among the baselines. On the Gowalla dataset with more than a million items, PQTopK requires much less time compared to backbone Transformer models. On the other hand, on smaller datasets with only a few thousand items (such as Booking.com), even Default Matrix Multiplication remains efficient.\nRQ2. PQTopK efficiency with very large catalogues. As observed in RQ1, the inference time of a backbone Transformer model (without scoring head) is constant w.r.t. catalogue size . Therefore, as our goal is efficiency analysis, we exclude the Transformer model from the analysis and simulate it using a random model output for each output. We also generate a random sub-id embedding matrix  to compute item scores. In all cases, we include the time required for selecting top-k (tf.math.top_k() in TensorFlow) after scoring, as this time also depends on the number of items in the catalogue.\nFigure 2  ###reference_### reports the mean response time for Default Transformer scoring, PQTopK and RecJPQ without the backbone Transformer model, for  splits (2a  ###reference_sf1###) and  splits (2b  ###reference_sf2###).\nBoth Figures 2a  ###reference_sf1### & 2b  ###reference_sf2### include the matrix multiplication-based Transformer Default baseline that does not use the number of splits.\nWe observe from the figures that with a a low number of items in the catalogue (), the default matrix multiplication-based approach is the most efficient, requiring less than a millisecond for scoring. However, as we observed in RQ1, with this small number of items, the actual method is not that important, as the scoring time is likely to be dominated by the backbone model inference.\nWith the smaller number of splits, , matrix multiplication becomes less efficient compared to PQ-based methods for item catalogues with more than  items. Note that the figure is shown in logarithmic scale, meaning that, for example, at 10M items, PQTopK is 10 more efficient compared to the default approach. Also, note that the matrix multiplication baseline only extends up to  items: after that point, the default approach exhausts all available system memory (128GB). We also observe that PQTopK is always more efficient than RecJPQ. Despite (due to the logarithmic scale) the lines looking close to each other, PQTopK is always faster than RecJPQ by 50-100%. For example, with 10M items in the catalogue, PQTopK requires 146ms per user, whereas RecJPQ requires 253ms (+68%). With 100M items in the catalogue, PQTopK remains relatively efficient ( 1 second per user); however, with 1 billion items, the method requires more than 10 seconds per user. Aruguably, 10 seconds per item is not suitable for interactive recommendations (for example, when the model inference occurs during web page loading), but may still work in suit situations when recommendations can be pre-computed (e.g. updated once every day).\nOn the other hand, as we can see from Figure 2b  ###reference_sf2###, with a large number of splits (), Default and PQtopK perform similarly; e.g., both methods require 100ms for scoring 1M items, 50ms faster than RecJPQ. However, on our hardware, Default consumes all available memory above 10M items (this is why the line for Default on Figures 2b  ###reference_sf2### and 2b  ###reference_sf2### does not go beyond  items), whereas PQTopK and RecJPQ allow for scores up to 100M items. Nevertheless, PQTopK scoring, in this case, requires 10 seconds per user, limiting its application to the pre-computing scenario.\nFinally, we observe that with catalogues with more than  items, the response depends linearly on the number of items for all scoring methods. However, with less than  items, there is a  \u201delbow-style\u201d non-linearity that can be explained by the fact that the time required by auxiliary operations such as function calls becomes important at this small scale.\nSummarising RQ2, we conclude that PQTopK with 8 splits is a very efficient algorithm that allows performing efficient inference on catalogues even with hundreds of millions of items. With a larger number of splits , the inference time of PQTopK is similar to the default matrix multiplication scoring, but it allows scoring up to  items. In contrast, matrix multiplication exhausts available memory with catalogues larger than  items, which highlights the importance of RecJPQ for reducing memory consumption.\n###figure_2### ###figure_3###"

We found that using RecJPQ enhancement, which enables training on large catalogues via sub-item-id representation, coupled with an efficient PQTopK scoring algorithm, allows model inference on large catalogues. In particular, using PQTopK, we sped up RecJPQ-enhanced SASRec 1.56 compared to the original RecJPQ scoring and 4.5 compared to default SASRec scoring on the Gowalla dataset with 1.3M items. We also showed that, when considering the pre-scoring scenario, PQTopK can be applicable to catalogues of up to 1 billion items. We believe that our findings will help the wider adoption of state-of-the-art Transformer-based models in real production environments."

Simplex codes are one-weight Griesmer -linear codes and they meet all Griesmer bounds of the generalized Hamming weights of linear codes. All the subcodes with dimension  of a -simplex code have the same subcode support weight  for . In this paper, we construct linear codes meeting the Griesmer bound of the -generalized Hamming weight, such codes do not meet the Griesmer bound of the -generalized Hamming weight for . Moreover these codes have only few subcode support weights.

Previous work has focused on isolated signs or comparison against a single reference video to assess Sign Languages (SL). This paper introduces a novel SLA tool designed to evaluate the comprehensibility of SL by modelling the natural distribution of human motion. We train our pipeline on data from native signers and evaluate it using SL learners. We compare our results to ratings from a human raters study and find strong correlation between human ratings and our tool. We visually demonstrate our tools ability to detect anomalous results spatio-temporally, providing actionable feedback to aid in SL learning and assessment.",

With the advancements in deep learning and computer vision, there has been a growing interest in modelling SL. The majority of methods focus on classification, namely for the recognition and translation of sign [30  ###reference_b30###, 4  ###reference_b4###], rather than improving or assessing SL proficiency. The standardisation of Sign Language Assessment (SLA) is a challenging research topic due to the many nuances that affect its legibility [14  ###reference_b14###].\nThe study of Sign Language Linguistics is still in its infancy, especially when compared to spoken languages. SL have no standardised written form, they are conveyed via a combination of manual and non-manual features [41  ###reference_b41###]. While the manual features include the location, orientation, and movement of the arms and hands; non-manual features refer to facial expressions, body posture, head movement, and eye gaze. Signing involves simultaneous combinations of these features, each influencing the meaning of a sign, adding multiple layers of linguistic complexity. In continuous sequences, co-articulation is also common factor [42  ###reference_b42###]. This includes temporal overlap between signs in a sequence leading to blending, spatial influence where the location of one sign may impact the starting location of the following signs, and handshape modifications based on context. Given the rich and complex nature of SL, skilled teachers are needed to assess and quantify signing proficiency.\nIn this paper we focus on SL assessment, proposing a tool to aid human teachers to evaluate continuous SL and to improve efficiency in evaluation and feedback. Teaching systems for SL that incorporate feedback mechanisms have been proposed using classification to determine correct from incorrect repetitions or to regress scores directly [49  ###reference_b49###, 54  ###reference_b54###]. However, most approaches are limited to the assessment of isolated signs [50  ###reference_b50###].\nOur work provides an SL assessment tool for continuous sequences that learns the natural distribution present in human motion. We develop a Skeleton Variational Autoencoder (SkeletonVAE) to embed signed sequences from multiple native signers in a compact, lower dimensional subspace. We then apply a Reference Selection technique over these embeddings to determine the most representative sequence from the collection of sequences. We finally model the Motion Envelope by aligning all the sequences to the reference and learning the distribution over the embedded data using a Gaussian Process (GP).\nWe test our model using data from SL learners and evaluate its performance against ratings collected from a human raters study. We demonstrate that our model can quantitatively evaluate the production of sequences achieving similar results to a manual rater. Furthermore, we show that our system can determine where and by what distance a learner falls outside of the natural acceptable variation in human motion for signed sequences."

We take our video dataset of sentences with multi-participant productions and encode them to create a secondary dataset of latent time varying embeddings. Second, we develop a Reference Selection technique which identifies a reference production of each sentence based on similarity calculation between all participants. Finally, we build a Motion Envelope by aligning each participant\u2019s sequence to its corresponding sentence reference and model the distribution of per-dimension embedding trajectories across multiple signers.

After this, we implement 3D pose uplift [19  ###reference_b19###] to regress accurate 3D skeleton data and convert to canonical form by choosing fixed bone lengths and applying this scaling via the joint angles. We now have  sequences of -dimensional skeleton joint-position data for sign language poses .\nWe assume that, within the context of human motion and SL, each pose lies on some manifold with fewer dimensions than  which we can approximate via a stochastic mapping  where  is a latent representation or embedding. Our goal is to model the time variation of  in terms of its compact representation .\nWe begin by taking the skeleton poses  and embedding them using a Variational AutoEncoder, which is trained via a process known as variational inference [3  ###reference_b3###, 16  ###reference_b16###, 26  ###reference_b26###]. Variational inference is concerned with maximising the Evidence Lower BOund (ELBO), which forms a lower bound on the negative log-likelihood of the data under the model:\nHere,  is known as the approximating posterior, which ideally matches the true posterior  which we do not have access to. We therefore assume a parameterisation for this approximating posterior, and define a prior distribution . The Kullback-Liebler divergence  is then used to create pressure such that the approximating posterior distribution  resembles this prior, and this pressure is weighted with a scalar  [16  ###reference_b16###]. Using a  value other than one means the ELBO cannot technically be fulfilled, but is a hyperparameter determined by experimental results. For our work the choice of prior is an isotropic Gaussian with mean  and variance . The parameters  and  represent the neural network parameters for the encoder and decoder respectively, and it is the encoder and decoder which parameterise the approximating posterior and conditional likelihood models. As such, each datapoint is encoded as a mean  and a variance  which, via the reparameterisation trick [27  ###reference_b27###], enable sampling  which are decoded to reconstructions . Finally, note that in Eq. 1  ###reference_###,  is the total number of datapoints available, across all  sentences and  signers (i.e.  for fixed ). This part of the modeling process therefore treats the data as independent and identically distributed (the sequential aspect of the data, as well as the fact we have different sentences being performed, will be modeled using Gaussian Processes).\nSince hands are high-frequency, low-amplitude signals due to their rapid and detailed movements compared to the larger, slower movements of the body, they can be lost in the noise during VAE training. To address this, we use L1 loss as the reconstruction loss and split the weighting of the loss between the hands and body. By setting a high  value, the network can better focus on hand reconstruction. Our overall loss function, Eq. 2  ###reference_###, is the sum of this reconstruction loss with the -scaled KLD. Once we have trained the VAE on all skeleton poses for the complete dataset, we arrive at a secondary dataset of encodings  where  represents the conditional mean encoding of the corresponding skeleton datapoint ."

SRTs often work with a binary concept of correctness [57  ###reference_b57###]. In this work a partial credit scale is used (as in [51  ###reference_b51###]) in order to provide more informative feedback to the participant.\nWe create our Swiss-German Sign Language (Deutschschweizerische Geb\u00e4rdensprache, DSGS) SRT dataset by recording a repetition test across 12 sentences of varying difficulty, determined by the number of signs, as well as morphological and syntactic complexity. The test is taken by a combination of 10 native signers and 14 language learners. Some examples of the sentences are shown in Tab. 1  ###reference_###. We use the data from the native signers as our gold standard for training our model and the learners\u2019 data for evaluation.\nWe extract 3D canonical skeleton pose data (as shown in Fig. 2(c)  ###reference_sf3###) for the dataset, with each pose represented by 61 nodes in 3D Cartesian space. We sort the native signer data to include only sentences which are produced in the sentence order matching the initial reference and use this data for training the GPs model.

Raters are trained on a standardised rubric and evaluate videos of the sentences across six criteria: manual components, mouth components, eyebrow movements, head movements, eye gaze, and sentence structure.\nEach criterion is assessed on a three-point scale, allowing for more nuanced feedback compared to a binary system. To ensure reliability, 14 videos are designated as anchor videos and are rated by all eight raters. The remaining 97 videos are assessed by two raters each in an overlapping design, with measures taken to balance video allocation and minimise potential bias. Analysis of the ratings provides inter-rater reliability, allowing us to determine the most reliable criterion for assessment.\nFor our experiments we choose to evaluate against the criterion for manual features on the sign produced by the language learners. Each rater provides a score for each manual component of the sign in the sentence. We take the mean of the ratings across the components in the sentence for each rater; and then take the mean across the raters that rated the sentence-learner pair. We repeat this for every sentence and learner. This provides a single score, 1 to 3, for each learner, for each sentence, that can be used for comparison with the output of our system."

The output of the encoder is split into two separate fully connected layers, each of size 10, representing the mean and log-variance of the latent space distribution. The mean and log-variance values are combined using the reparameterisation trick to calculate a 10-dimensional z-value vector. The decoder mirrors the structure of the encoder. It takes the 10-dimensional latent vector and passes it through two hidden layers, of size 50 and 100 respectively.

For each  in the test sequence, we calculate the probability density of the learner with respect to the learnt distribution at that point in the sequence for each latent dimension, resulting in a multidimensional mean. We then take the average of this mean, resulting in a single score for signing proficiency which we refer to as the Probability Density Measure (PD Measure). We expect a learner assigned a high manual rating to receive a high PD Measure and vice versa.\nThe second method quantifies the number of instances where the learner deviates from the distribution defined by the Motion Envelope, we refer to this as the Out of Distribution Count. Specifically, this method counts the occurrences where the learner falls outside the high confidence region, summing across all dimensions. The high confidence region is defined as the region that covers where we expect the true function values to lie with 95 percent probability [39  ###reference_b39###]. This method is particularly effective at assessing anomaly detection. We expect a learner assigned a high manual rating to receive a low Out of Distribution Count and vice versa.\nWe standardise the resulting scores from our model and the manual ratings data using z-scoring standardisation. We apply the standardisation across each rater individually for all their ratings which increases the comparability of ratings from different raters. We then apply the standardisation on a per sentence level for the output scores of our system and the manual ratings. This results in standardised beta coefficients (which range from -1 to +1) when performing the regression analysis."

A notable result here is the difference in scores when assessing using the PD Measure or Out of Distribution Events. For sentences A, B, C, E, G, I, K, L the first method achieves the best results, where as for sentences D, F, H, J the second method performs better. Both methods can be deemed useful. The PD method provides a more complete score over the entire sequence as all points in time are used in its calculation. However, it may be skewed negatively by acceptable deviations in sentence productions that are within distribution but far from the mean, as these will score relatively low compared to those with smaller distances to the mean of the distribution.\nThe Out of Distribution Count method only incorporates events into the score when the threshold is exceeded, providing a good method for anomaly detection, countering the downside of the PD method mentioned above.\nFor some of the sentences, the results for the PD measure and Out of Distribution Count are both low. One reason for this may be due to a non-linear relationship between the manual ratings and the output of the system. To investigate this we present results using the Spearman Rank Correlation Coefficient."

When looking at the Many Facets Rasch Measurement [37  ###reference_b37###] for severity among raters, it becomes apparent that the sample is an outlier due to it being rated by the two most severe raters.

Learner 5 receives a low overall single score from our system and is similarly rated by the manual raters whereas for Learner 13 the opposite is true, receiving high scores. As such these two language learners make a good example for further evaluation.\nThe plot on Fig. 4  ###reference_### shows time varying latent signals from one of the SkeletonVAE dimensions for Sentence A ranging from Pose Number 150 to 250 for learners and native signers against the learnt Motion Envelope confidence region. Learner 5 is shown leaving the learnt confidence region at pose number 170, with its greatest distance from the distribution occurring at 175 before returning to the distribution. On the contrary to this, Learner 13 stays within distribution throughout the sequence, coming close to the upper bounds at point but remaining within the confidence region, indicating its variation is acceptable.\nThis visualisation demonstrates the pipelines ability to temporally determine where anomalies have occurred, and by how far they differ from the learnt distribution over natural variations. The latent signals from three of the native signers used to train the Motion Envelope for this sentence are visualised to demonstrate examples of the natural variation in SL between deaf individuals.\nThe decoded pose sequences for the two learners and one of the native signers are displayed below the plot, focusing on the region where the anomaly occurs. We take the latent signals between Pose Numbers 165 and 185 and decode them using the SkeletonVAE visualising every fifth pose within the range. At 165 the poses for the two learners are similar to each other, and slightly differ from the Native Signer, but stay within a margin of error. At 170, the arms of Learner 5 move in the opposite direction to Learner 13 and the native signer, who start to converge. At 175, Participant 13 is furthest in pose from the other two examples, with the wrong arm in the air. This is reflected as the point at which the participant is furthest from the learnt distribution. After this, the learner starts to move towards the direction of the learnt distribution, finally converging back with the other two examples as shown at pose number 185. This visualisation provides a spatial context of the error occurring in the skeleton space."

Previous work has focused on isolated signs, classification, or comparison against a single reference video to assess SL. In this paper, we proposed a novel assessment system to assess the comprehensibility of continuous SL sequences by modelling the natural distribution in human motion over multiple native deaf participants.\nOur experiments demonstrated that modelling using multiple native signers can lead to robust and interpretable results. This approach can be used to provide visual feedback to users in spatio-temporal contexts to aid in SL learning and assessment. We evaluated our results using real data from language learners and showed strong correlation between manually rated data and our approach.\nAs future work, we would like to expand our system to include non-manual feature assessment as these are important linguistic features that modify the meaning of SL."

+            "text": "The development of autonomous vehicle technology has significantly transformed urban mobility and transportation systems. At the forefront of these innovations is Apollo Go [1  ###reference_b1###], Baidu\u2019s autonomous ride-hailing service, which has seen substantial deployment in various Chinese cities. Apollo Go showcases the capabilities of autonomous driving technology and highlights its potential for improving urban mobility by reducing traffic congestion and enhancing transportation efficiency. With continuous advancements in sensing, automation, and computing technologies, autonomous driving is becoming increasingly accessible. It is expected to revolutionize future transportation systems by enhancing traffic safety [2  ###reference_b2###], smoothing traffic flow [3  ###reference_b3###], and improving transportation energy efficiency [4  ###reference_b4###, 5  ###reference_b5###]. While many of the potential benefits of autonomous vehicles (AVs) depend on achieving a high market penetration rate (MPR) [6  ###reference_b6###], recent studies indicate that even a modest MPR of intelligently controlled AVs can significantly enhance traffic flow [7  ###reference_b7###]. Recently, Baidu Apollo Go has been widely deployed as a robotaxi service in major cities like Beijing and Wuhan, offering a glimpse into the future of urban mobility.\nAccording to recent studies [8  ###reference_b8###, 9  ###reference_b9###], the deployment of autonomous ride-hailing services like Apollo Go has led to a paradigm shift in the urban transportation landscape. These services offer an alternative to traditional taxis and ride-hailing companies, aiming to provide safer, more reliable, and cost-effective transportation options. Wang et al. [10  ###reference_b10###] found that transferring autonomous vehicle technology between autonomous and traditional ride-hailing platforms can create a win-win scenario with higher profits for both platforms. While the integration of autonomous vehicles into the transportation network presents numerous benefits, it also introduces new challenges and considerations that need to be addressed. The public generally holds a cautious attitude towards autonomous taxis, as technological advancements and their reliability and functionality encourage trust, but concerns about potential job loss and the technology being dehumanizing foster negative sentiment [11  ###reference_b11###]. Even before the advent of autonomous ride-hailing services, new mobility services offered by TNCs, such as Uber and Lyft, had already dominated the market and changed transportation systems. However, while TNCs are successful in providing more choices for travelers, not all the impacts associated with TNCs are beneficial. For example, Komanduri et al. [12  ###reference_b12###] show that the competitiveness of the TNC provider RideAustin versus transit has negative impacts on public transportation. Clewlow et al. [13  ###reference_b13###] studied the capacity utilization rate of taxis and TNCs in five major U.S. cities (Boston, Los Angeles, New York, San Francisco, and Seattle) in terms of time utilization rate and mileage utilization rate. The findings show that almost half of taxi and TNC operation time is not utilized. Inefficient operation lowers profit and leads to more congestion and emissions in urban cores where taxis are cruising for the next ride.\nPublic opinion on using shared autonomous transportation in everyday life is quite divided. On the one hand, the safer people perceive autonomous vehicles to be, the more likely they are to use them, as they reduce the risk of collisions caused by traffic violations and human errors [14  ###reference_b14###]. Research indicates that high-income tech-savvy men living in urban areas and experiencing greater traffic accidents are more interested in these new technologies and are willing to pay more for them [15  ###reference_b15###]. Integrating autonomous driving with traditional public transportation can also improve mobility for the elderly and disabled [16  ###reference_b16###]. On the other hand, there is no consensus on the benefits of autonomous driving. Around half of the people express concerns about safety issues related to traffic accidents, robbery, and hacking [17  ###reference_b17###]. Additionally, there are worries about the safety of autonomous vehicles operating alongside pedestrians and traditional vehicles in complex urban environments [18  ###reference_b18###], as well as negative feelings about potential job losses and employment-related social exclusions related to automation [19  ###reference_b19###]. Currently, Apollo Go, China\u2019s first shared autonomous driving service platform operating in multiple cities, is scaling up its passenger testing operations. Gaining insights into public interest and perception is crucial for improving the platform\u2019s services.\nWith the rapid development of internet technology, social media platforms such as Twitter, Facebook, LinkedIn, Weibo, and others have become important channels for people to share their experiences and exchange views. As a carrier of public opinion, social media offers researchers a wealth of perspectives and thoughts due to its immediacy and diversity. Chinese social media platforms such as Weibo often include the location and time of the post when users publish content, associating these posts with specific places or events. Additionally, the tags included in the posts facilitate thematic categorization. Moreover, the content of the posts can reflect the cognition, emotions, and attitudes of the individuals posting them [20  ###reference_b20###, 21  ###reference_b21###, 22  ###reference_b22###]. These cognitive, emotional, and attitudinal factors significantly influence people\u2019s choices of transportation modes [23  ###reference_b23###]. From a statistical perspective, analyzing the content of posts or tweets on social media to extract collective cognition, emotions, and attitudes can help identify potential factors influencing people\u2019s choices regarding autonomous transportation.\nRecent developments in AI technology can be helpful in processing such massive text data for the analysis of transportation systems. Deep learning [24  ###reference_b24###] has demonstrated promising capabilities in explaining complex nonlinear relationships and outperforming traditional approaches in various tasks such as image classification [25  ###reference_b25###] and natural language processing [26  ###reference_b26###]. It has also become a popular tool in the transportation community. For example, Cui et al. [27  ###reference_b27###] used a Long Short-Term Memory (LSTM) neural network to predict network-wide traffic speed, while Li et al. [9  ###reference_b9###] forecasted taxi demand and optimized city-wide taxi operations using an LSTM neural network. Deep learning is not only utilized in macroscopic traffic phenomena [27  ###reference_b27###, 9  ###reference_b9###] but also widely applied to microscopic traffic phenomena, such as driving behavior models [28  ###reference_b28###, 29  ###reference_b29###].\nOne of the techniques used on social media for studying emotions and attitudes is Sentiment Analysis [22  ###reference_b22###, 21  ###reference_b21###, 30  ###reference_b30###]. Sentiment analysis is a key application of Natural Language Processing (NLP) that relies on various NLP techniques, including lexicon-based approaches, machine learning, and deep learning techniques, to classify text into sentiment categories such as positive, negative, and neutral [31  ###reference_b31###]. NLP is an essential field in computer science and artificial intelligence, focused on enabling computers to comprehend and interact with human language. The evolution of NLP has been remarkable, starting with rule-based methods as documented in [32  ###reference_b32###], then shifting to statistical approaches as seen in [33  ###reference_b33###], and finally embracing deep learning techniques highlighted in [34  ###reference_b34###]. In the current landscape, NLP has reached a new milestone characterized by the advent of large, pretrained language models. The BERT model [35  ###reference_b35###] stands out as a prominent example of this new era in NLP.\nSocial media sentiment analysis can more efficiently identify emotional tendencies with the help of pretrained language models [36  ###reference_b36###]. Furthermore, fine-tuning techniques preserve the pretrained knowledge of these large models while significantly reducing the amount of labeled data and training time required [37  ###reference_b37###].\nText on social media often contains metaphors, harsh data, and the coexistence of many possible meanings for individual words or phrases, posing significant challenges to semantic understanding. For example, BERT\u2019s exceptional capability to discern sentiments within COVID-19-related tweets, a proficiency that can be applied to analyze transportation discourse during the pandemic with enhanced precision [38  ###reference_b38###]. The use of BERT models for travel pattern classifiers to determine whether each tweet is related to certain travel patterns and conduct sentiment analysis is to understand changes in people\u2019s attitudes towards pattern selection during the pandemic [21  ###reference_b21###]. A hybrid model that fuses BERT with BiLSTM and BiGRU for sentiment analysis of airline-related tweets demonstrates BERT\u2019s practical utility in interpreting customer sentiment\u2014a key asset for the transportation industry [39  ###reference_b39###]. In these studies, the preprocessing phase primarily entails text cleansing and normalization, tokenization, and length adjustment to ensure uniformity and proper formatting, with tailored refinements made to accommodate specific elements like URLs, mentions, topic tags, special characters, and extraneous content [40  ###reference_b40###, 38  ###reference_b38###, 21  ###reference_b21###, 39  ###reference_b39###]. At present, the technology specifically used for sentiment analysis relies on established NLP preprocessing techniques and does not use effective data initialization and preprocessing techniques, which will seriously affect the performance of sentiment analysis models [41  ###reference_b41###].\nFor robotaxis, there are certainly benefits in energy utilization [42  ###reference_b42###], such as low carbon development, but at the same time, people are concerned about their safety, and crashes have already happened [43  ###reference_b43###]. Since Apollo Go has just been deployed in China and gained popularity early this year, and we do not have access to its trajectory data and OD data, it is not possible to study explicitly how it will influence the current traffic patterns. However, we are interested in understanding how the general public perceived this revolutionary service before it was widely deployed citywide and in other cities. We use crawled Weibo data obtained via API to study public opinion on this revolutionary service in China.\nThe goal of this study is to provide a scenario to observe how the general public reacts to the rapid and large-scale deployment of robotaxis using real-world data from Weibo. Specifically, this paper aims to answer the following three questions:\nHow can we use natural language data to better understand new mobility services?\nWhat is the general public\u2019s emotional reaction to the sudden appearance of the robotaxi?\nWhat suggestions and insights can be informed to the public and transportation agencies?\nThe remainder of this article is outlined as follows. First, we provide a review of the relevant literature on mobility services and the methodologies used in this study. Second, we give a detailed summary of the experimental data, including data collection, processing, and the study sites. Third, we implement the proposed methods and present the results of our analysis. Finally, we conclude with a discussion of the findings from this study and directions for future research."

Due to the difficulty in identifying the information on the posters and concerns regarding online privacy protection, there are issues such as ambiguous spatial locations and varying quality of comments. This presents challenges for data cleaning and analysis. However, these data include all topic data from January to July 2024, which is sufficient to conduct sentiment analysis on public opinion using natural language processing. The \u2019Content\u2019 column contains over 30,000 public views posted by Weibo users located in different regions across China. Therefore, the dataset spans a total of six months before and after the peak period, with data publication locations covering all provinces, municipalities, and autonomous regions in China, which is sufficient for sentiment analysis.\nBy using the Weibo API service, 36,096 Weibo posts and comments containing the \u201cBaidu Apollo Go\u201d tag from January to July 2024 were collected (Figure 1  ###reference_###). The data contains user name, IP location, time, attitude count, content, and other relevant information. A sample dataset is shown in Table 1  ###reference_###. The username column uniquely identifies each user, the content column records the text or emoji content posted by each user, and the location column records the IP address from which each comment was posted. For privacy protection, the IP locations for each record are only accurate at the province or municipality level. As discussed above, these data will be used to analyze people\u2019s attitudes toward the Baidu Apollo Go service. The content column contains user comments or experiences with the Baidu Apollo Go service.\n###figure_1###"

Records posted by these accounts were dropped directly due to their lack of clear attitude as their content focused on describing facts.\nAfter removing official information, unrelated content needed to be identified through manual annotation. Some users posted long texts, such as blogs recording their daily activities, where Baidu Apollo Go is mentioned but not the main focus. However, some users expressed their attitudes within a sentence in the long text. These records should be annotated to capture the attitude and not be dropped.

Studying these areas provides insights into public attitudes where autonomous vehicles are becoming more integrated into daily life. While focusing on the provinces where Apollo Go operates, our study also considers data from non-operational provinces. This broader perspective ensures that we capture public sentiment from regions with different levels of exposure to autonomous vehicle technology. This approach allows us to examine regional differences in acceptance, concerns, and overall sentiment towards Baidu\u2019s Apollo Go.\n###figure_2###"

From this extensive dataset, we selected a sample of 2,697 posts for detailed labeling and fine-tuning. The first step involved meticulously labeling these selected posts. Posts that were deemed irrelevant to Apollo Go were labeled as \u2019Drop\u2019. The remaining posts were categorized based on their sentiment into three groups: positive, neutral, and negative. This categorization allowed us to analyze the sentiment distribution and understand public perception more effectively.\nTo analyze the sentiment of all collected Weibo posts, we fine-tuned the \u2019bert-base-chinese\u2019 model [35  ###reference_b35###], which is pre-trained specifically for the Chinese language and available on Hugging Face. This model was chosen for its proven effectiveness in handling Chinese text, its ability to capture contextual nuances, and its strong performance in various natural language processing tasks. Fine-tuning the BERT model involved training it specifically on our labeled dataset of Weibo posts.\nThe following hyperparameters were utilized during the training process: the learning rate was set to 1e-05, ensuring minimal updates during fine-tuning to make subtle adjustments to the pre-trained BERT model\u2019s parameters. This approach enables the model to adapt to our specific tasks without significantly disrupting the representations it has already learned. The training batch size and evaluation batch size were both set to 8, balancing computational efficiency and model performance. A seed value of 42 was used to ensure reproducibility. The Adam optimizer, configured with betas of (0.9, 0.999) and an epsilon value of 1e-08, was employed. The learning rate scheduler was of the linear type, and the model was trained over 5 epochs. This adaptation aimed to enhance the model\u2019s performance in sentiment classification of Apollo Go-related content.\nAfter the fine-tuning process, the model achieved an accuracy of 0.59. This accuracy indicates the model\u2019s capability to correctly classify the sentiment of Weibo posts, demonstrating the feasibility of using BERT for sentiment analysis in this context.

This matches news articles that Apollo Go was commercially operated in Wuhan, Hubei in July, and this topic became popular over the internet. Under this situation, we separated the analysis into two-time phases, January to June and July, to analyze the change in attitudes and the Spatial distribution of attitudes on Weibo. This analysis is detailed in Figure 5(a)  ###reference_sf1###, Figure 5(b)  ###reference_sf2### and Table 5  ###reference_###.\n###figure_4### From January to July, public attitudes towards Apollo Go were predominantly positive. In early July, \u201dApollo Go\u201d gained significant public attention after trending on social media. On May 15, 2024, Baidu Apollo hosted the Apollo Day 2024 event in Wuhan, which showcased the latest autonomous driving foundation model, generating significant media coverage and public interest. The discussion around the service surged from July 8th, reaching a peak on July 12th, before gradually declining. Enthusiasm for this service continues to grow due to the novelty of the technology and perceived improvements in ride-hailing quality and convenience. However, from July onwards, as the volume of public discourse increased, the proportion of negative comments began to rise. Concerns about job displacement due to the automation of driving roles became more pronounced. Additionally, some users expressed dissatisfaction with the presence of safety operators in the vehicles, feeling that it undermined the autonomy of the service. This shift in sentiment highlights the complex characteristics of public attitudes towards autonomous vehicles. While there is considerable enthusiasm for technological advancements and potential benefits, there are also significant concerns and resistance, particularly related to socioeconomic impacts and the perceived authenticity of the autonomous experience.\n###figure_5### ###figure_6### ###figure_7### ###figure_8###"

Beijing and Shanghai have also ranked high on the discussion board tables. Most of the relevant conversations came from these regions making them all top four dispensers for discourse during the first few months of 2024. Comparing July with the initial six months, it seems that Apollo Go has enjoyed robust adoption in the Chinese mega-cities. Guangdong and Beijing significantly increased postings in July, and most of the top 10 cities 6  ###reference_### increased posts nearly tenfold in July. However, Hubei didn\u2019t increase as much compared to other provinces. The level of discussion abroad has also surpassed that in Wuhan. This might be caused by the discussion in Hubei becoming localized and primarily happening offline.\n###figure_9### ###figure_10### The spatial distribution of public attitudes towards the Apollo Go from January to July was analyzed. Figure 9  ###reference_### depicts the distribution of the number of each attitude category across various regions, while Figure 10  ###reference_### illustrates the corresponding percentage distribution. Both maps utilize a color gradient to convey the proportion of attitudes: negative attitudes are represented in blue, neutral attitudes in green, and positive attitudes in red.\nThe eastern coastal provinces show a higher level of discussion intensity regarding Apollo Go, particularly in Beijing, Guangdong, and Shandong. Public concerns predominantly focus on employment issues and the perceived irreplaceability of human work in the era of artificial intelligence. There is a strong correlation between the provinces with high discussion intensity and those where Apollo Go operates. Some individuals express excitement due to Apollo Go\u2019s competitive pricing compared to traditional ride-hailing services. Conversely, interest in Apollo Go is relatively lower in western regions, and attitudes vary significantly among provinces. Xinjiang and Qinghai provinces are predominantly shaded in deep red, indicating optimism about the unstoppable trend of autonomous driving and anticipation for its development. Tibet and Gansu provinces are primarily shaded in deep blue, reflecting concerns about the impact of autonomous vehicles on traditional taxi and ride-hailing services.\n###figure_11### ###figure_12### From 8 July to 14 July, the spatial characteristics of panel data reveal several trends. In terms of quantity, as shown in Figure 13  ###reference_###, there is a general trend of high attention across coastal provinces, even in regions where Apollo Go does not operate. This suggests a pervasive interest in autonomous ride-hailing services, possibly influenced by media coverage and broader technological discourse. Specifically, Xinjiang stands out with exceptionally high attention compared to other western and northern provinces, indicating a unique regional interest in the topic.\nIn terms of percentages, as depicted in Figure 16  ###reference_###, the analysis focuses on the period from July 10 to 14 to discuss public attitude changes, as initial days show lower data volume, making them less representative of public attitudes. Overall, there is an expansion in the coverage of positive attitudes and a reduction in the coverage of negative attitudes. The percentage of neutral attitudes is evenly distributed across provinces, suggesting widespread public awareness of Apollo Go facilitated by news and other social media content over time. Provinces with high values of positive attitudes typically align with provinces where there are also high values of neutral attitudes. This alignment often corresponds to regions where there has been extensive media coverage of Apollo Go\u2019s operations or advancements in autonomous driving technology. This indicates that media coverage plays a crucial role in shaping public attitudes towards Apollo Go. News reports effectively highlight the benefits of autonomous ride-hailing services such as convenience and technological advancements, thereby mitigating public concerns surrounding the technology.\n###figure_13### ###figure_14### ###figure_15### ###figure_16### ###figure_17### ###figure_18### ###figure_19### ###figure_20### ###figure_21### ###figure_22### ###figure_23### ###figure_24### ###figure_25### ###figure_26###"

This study evaluates public sentiment toward Baidu Apollo Go, a leading autonomous ride-hailing service provider in China, by analyzing social media data, particularly from Weibo. Our analysis reveals a divergence in public perceptions of shared self-driving transportation.\nPublic interest in autonomous ride-hailing services varies both temporally and geographically, predominantly concentrated in China\u2019s economically developed regions. Initially, the discussions on Weibo gradually shifted from Hubei province to the provinces and cities where autonomous ride-hailing services were launched. In the later stage, those placed with no Apollo Go available, we have seen more and more people are expressing their interests, suggesting that trial runs and public testing have helped to increase public awareness of such services. Similar research has also shown that social incidents are more sensitive to the general public [48  ###reference_b48###, 49  ###reference_b49###], indicating that effectively utilizing such cases can help expose the service to a broader audience.\nAs for the public comments, our word frequency analysis indicates frequent mentions and comparisons with Baidu\u2019s competitors, including Tesla and Waymo. This competitive landscape is a focal point in the discussions on Chinese social media. Positive comments predominantly highlight technological innovations and the unique experiences offered by autonomous driving, which is similar with studies conducted in the U.S. [48  ###reference_b48###]. In contrast, negative comments primarily express concerns about safety issues and social implications, especially job losses, while neutral comments often focus on brand-related keywords. The difference is that in other parts of the world, there is more discussion about personal privacy and data security [50  ###reference_b50###]. This discrepancy may be attributed to the longer timeframe for the launch of self-driving services in those regions, allowing for a broader range of issues to surface. Interestingly, in China, some comments reflect dissatisfaction with traditional ride-hailing drivers\u2019 behaviors, such as smoking and chatting, suggesting a preference for the perceived comfort and reliability of autonomous services.\nIn comparison, countries like the U.S. and the U.K. have seen similar developments, with services like Waymo One and Oxbotica expanding operations in major cities. However, discussions in the U.S. tend to focus more on cities already implementing or planning to deploy these services, such as San Francisco, Phoenix, and Detroit  [47  ###reference_b47###]. This also reminds us of an advantage of using Weibo data: it contains the user\u2019s real IP address, offering a more precise measure of geographical data compared to X (Twitter), where users\u2019 locations are only inferred from their text.\nDespite these insights, this study has several limitations. Firstly, the lack of social demographic information, such as age and income, limits our understanding of the factors influencing public attitudes. Existing studies have shown that these attributes are critical in shaping public perceptions [46  ###reference_b46###]. Secondly, the data volume and time span are relatively small, with discussions on social media platforms heating up late in the study period. In contrast, other similar studies typically observe data continuously for about three months [50  ###reference_b50###, 47  ###reference_b47###], offering a more comprehensive view of public sentiment over time.\nMoving forward, it would be beneficial for future research to explore the impact of various demographic characteristics on public attitudes and to extend the observation period for a more comprehensive analysis. It could also helpful in combining social media data with other traditional datasets. Such findings can serve as crucial references for planners, policymakers, and service providers aiming to promote autonomous ride-hailing services. Effective strategies might include enhancing public outreach, conducting trial rides, and refining legal frameworks to mitigate potential negative impacts, such as job losses or liability issues in accidents. With these measures, the future of autonomous ride-hailing services looks promising."

+    "abstract": "The use of Artificial Intelligence (AI) in healthcare, including in caring for cancer survivors, has gained significant interest. However, gaps remain in our understanding of how such AI systems can provide care, especially for ethnic and racial minority groups who continue to face care disparities.\nThrough interviews with six cancer survivors, we identify critical gaps in current healthcare systems such as a lack of personalized care and insufficient cultural and linguistic accommodation. AI, when applied to care, was seen as a way to address these issues by enabling real-time, culturally aligned, and linguistically appropriate interactions.\nWe also uncovered concerns about the implications of AI-driven personalization, such as data privacy, loss of human touch in caregiving, and the risk of echo chambers that limit exposure to diverse information.\nWe conclude by discussing the trade-offs between AI-enhanced personalization and the need for structural changes in healthcare that go beyond technological solutions, leading us to argue that we should begin by asking, \u201cWhy personalization?\u201d",

These behaviors are critical because they shape patient-provider interactions and significantly impact treatment outcomes. Scholars argue that healthcare strategies must adapt to individual emotional states and information preferences to improve these interactions and ensure more effective treatment (Sankaran et al., 2019  ###reference_b40###; Bertrand et al., 2023  ###reference_b3###).\nThe issue is of relevance to the HCI and CSCW community since digital platforms are increasingly leveraged by cancer survivors and caregivers to gain health information (Chen\net al., 2013  ###reference_b9###; Burgess\net al., 2022  ###reference_b5###; Jacobs\net al., 2014  ###reference_b21###).\nIt is estimated that approximately 45% of cancer patients use digital platforms for information (Hesse et al., 2005  ###reference_b19###).\nScholars have argued for personalized technology solutions that cater to the unique circumstances and needs of cancer survivors and their caregivers (Nikkhah et al., 2022b  ###reference_b32###; Suh et al., 2020  ###reference_b46###), supporting the aims of identifying gaps in current technologies and proposing innovative design ideas (Randazzo et al., 2023  ###reference_b38###; Del Sette\net al., 2023  ###reference_b11###).\nMoreover, the exploration of health information-seeking behavior provides critical insights into the complexities of patient care and self-management, particularly for those navigating chronic diseases like cancer (Song\net al., 2022  ###reference_b45###; Zghab et al., 2024  ###reference_b52###).\nWe live in an era of AI Realism where AI is pervasive (Gautam, 2024  ###reference_b17###).\nThere is a growing trend of developing AI solutions for healthcare, including supporting cancer survivors (Sebastian and\nPeter, 2022  ###reference_b41###; Parimbelli\net al., 2021  ###reference_b34###).\nIn particular, AI-based solutions are positioned as promising tools, including in improving access to personalized information (Chanda\net al., 2021  ###reference_b7###; Murnane et al., 2018  ###reference_b29###; Tarver and\nHaggstrom, 2019  ###reference_b49###).\nWe examine some of the needs and build on the findings to chart out the scope of possibilities and dangers in leveraging AI to support cancer survivors."

I was very comfortable talking with them about it \u2026 It was therapeutic to talk about it, and it helped alleviate some of my anxiety as well.\u201d\nLikewise, two participants emphasized the significance of receiving support from their religious communities.\nP1, for example, emphasized the important role her church members played in supporting her, \u201cMy church consistently shows its support, makes it really clear that they are there for us, praying for us, and they are watching over us.\u201d\nSome participants also reached out online for support.\nTwo participants, P5 and P6 also reported reaching out to cancer survivors online for support both during and after their treatment.\nFor example, P6 noted, \u201cI have met a lot of people that have similar cancer experience, and they are willing to offer support and communicate.\u201d\nSimilarly, P5 shared the value of going through the journey together, \u201cI received a lot of support and was told that, having gone through a similar trauma, if others can survive, so can I. It may seem like there\u2019s no end in sight, but if I keep fighting, I can win too.\u201d\nIn these instances, the participants were seeking information and support that aligned with their cultural practices.\nOur participants were from minoritized identities and felt they were outsiders, as we could hear in P1\u2019s account, \u201cI didn\u2019t feel that the services considered my cultural background, which affected how I received the support.\u201d\nFive participants\u2019 experiences suggested the importance of culturally sensitive interventions that respect and address the distinct needs of various communities.\nFor example, P5 noted, \u201cIt would be great if the healthcare provider had the same or a similar ethnic or religious background, as it can help lay the foundation for trust in the relationship. I appreciate being able to receive culturally sensitive care that respects my spiritual needs.\u201d\nAsian communities often rely on traditional methods for health, including cancer treatment. Participants like P3 felt that their ongoing services did not acknowledge traditional perspectives, \u201cIt\u2019s hard to find culturally sensitive support that understands my specific community\u2019s viewpoint on cancer.\u201d\nSimilarly, participants expressed challenges in overcoming language barriers when interacting with healthcare providers, as heard in P6\u2019s account, \u201cI\u2019m facing a language barrier, so it would be perfect if the healthcare provider could help translate.\u201d\nP4 stated that she reached out to her family for help, \u201cMy English is not good, I need to ask my daughter to translate for me.\u201d\nThese accounts of participants reaching out to family and friends, communities near them, and online groups suggest the importance of social support.\nIt also highlights the critical ways in which people are trying to navigate and access personalized support that meets them where they are in their cancer journey."

AI systems can help healthcare providers learn about cultural practices and support real-time translation (Chen and Decary, 2020  ###reference_b8###), enabling effective communication across different linguistic abilities (Liu\net al., 2024  ###reference_b26###).

There is a need for institutional and infrastructural approaches.\nHowever, the primacy of AI solutions risks overlooking the urgent need to address the broader structural issues that impact cancer care and healthcare more generally."

+            "text": "Our findings highlight that personalization was viewed as a response to underlying issues encountered during cancer care, such as limited transparency and control over care practices, high costs of care services, and a lack of culturally sensitive support. We argue for the importance of asking \u201cWhy personalization?\u201d to surface and engage with underlying issues before designing for personalization.\nAsking \u201cwhy personalization?\u201d encourages undertaking a participatory approach, bringing the cancer care survivors into the design process.\nParticipatory approach, when well designed, can help cancer patients gain power and control over their care processes.\nCritical health and technology literacy, making available broader sources of information and care, and situating technology in the context of structural issues surrounding healthcare are necessary conditions to support agentic participation in the design process.\nIn the case of technology for personalization, the growing trend of involving people impacted by AI systems in the design process could provide a path forward.\nBut echoing Delgado\net al. (2023  ###reference_b12###) and Birhane et al. (2022  ###reference_b4###), we urge scholars and practitioners aiming to engage in participatory AI to pay attention to who is involved and how they are involved.\nAs our findings show, participants, even though they share some common elements of their identity (e.g., cancer patient), are not homogenous and have differing needs and desires.\nSimilarly, systems of care are multi-faceted and complex.\nEach would require and desire different kinds and degrees of participation.\nSome may require not using AI; an option that should be made available to people who are purported to be supported by the care infrastructure."

This manuscript addresses open questions about the numerical stability of various block classical Gram-Schmidt variants that have been proposed in the past few years. An abstract framework is employed, the flexibility of which allows for new rigorous bounds on the loss of orthogonality in these variants. We first analyze a generalization of (reorthogonalized) block classical Gram-Schmidt and show that a \u201cstrong\u201d intrablock orthogonalization routine is only needed for the very first block in order to maintain orthogonality on the level of the unit roundoff.",

+            "text": "With the advent of exascale computing, there is a pressing need for highly parallelizable algorithms that also reduce communication, i.e., data movement and synchronization. An underlying kernel in diverse numerical linear applications is the orthogonalization of a matrix, whose efficiency is limited by inner products and vector normalizations involving synchronization points (sync points), which dominate communication costs. In the case of an inner product or norm, a sync point arises when a vector is stored in a distributed fashion across nodes: each node locally computes part of the inner product and then must transmit its result to all other nodes so that each can assemble the full inner product. Communication-avoiding methods such as -step Krylov subspace methods have proven to be effective adaptations in practice; see, e.g., [1  ###reference_b1###, 6  ###reference_b6###, 16  ###reference_b16###, 24  ###reference_b24###]. Such methods implicitly rely on a stable block Gram-Schmidt (BGS) routine that should itself be communication-avoiding. Blocking alone reduces the number of sync points, as previously vector-wise operations can instead be performed on tall-skinny matrices or block vectors, thus replacing single inner products with block inner products and normalizations with low-sync QR factorizations. Low-sync variants of BGS have attracted much recent attention [4  ###reference_b4###, 8  ###reference_b8###, 9  ###reference_b9###, 7  ###reference_b7###, 20  ###reference_b20###, 21  ###reference_b21###, 24  ###reference_b24###, 23  ###reference_b23###, 25  ###reference_b25###], but their stability, in particular how well they preserve orthogonality between basis vectors, is often poor, which can lead to issues in downstream applications like Krylov subspace methods, least-squares, or eigenvalue solvers. Understanding the floating-point stability of low-sync BGS methods is thus imperative for their reliable deployment in exascale environments.\nTo be more precise, we define a block vector  as a concatenation of  column vectors. We are interested in computing an economic QR decomposition for the concatenation of  block vectors\nWe achieve this via a BGS procedure that takes  and a block size  as arguments and returns an orthogonal basis , along with an upper triangular  such that . Both  and  are computed block-wise, meaning that  new columns of  are generated per iteration, as opposed to just one column at a time.\nIn addition to sync points, we are also concerned with the stability of BGS, which we measure here in terms of the loss of orthogonality (LOO),\nwhere  is the  identity matrix and  denotes a computed basis with floating-point error. We will also consider the relative residual\nand relative Cholesky residual,\nwhere  is the computed version of  with floating-point error and  denotes the induced 2-norm. The residual (3  ###reference_###) measures how close a BGS method is to correctly computing a Cholesky decomposition of , which can provide insight into the stability pitfalls of a method; see, e.g., [8  ###reference_b8###, 12  ###reference_b12###].\nThe ideal BGS would require one sync point per block vector and return  and  such that (1  ###reference_###)-(3  ###reference_###) are , where  denotes the unit roundoff, without any conditions on , except perhaps that the 2-norm condition number  is no larger than . To the best of our knowledge, no such BGS method exists, and one must make trade-offs regarding the number of sync points and stability. In practice, the acceptable level of the LOO is often well above machine precision; e.g., the Generalized Minimal Residual (GMRES) method is known to be backward stable with Arnoldi based on modified Gram-Schmidt (MGS), whose LOO depends linearly on the condition number of  [14  ###reference_b14###]. A similar result for block GMRES remains open, however [5  ###reference_b5###].\nA key issue affecting the stability of a BGS method is the choice of intraorthogonalization routine, or the so-called \u201clocal\u201d QR factorization of a single block column; in the pseudocode throughout this manuscript, we denote this routine as \u201cintraortho\u201d or simply IO. Traditional Householder QR (HouseQR) or Givens QR (GivensQR) are common choices due to their unconditional  LOO, but they introduce additional sync points [15  ###reference_b15###, 13  ###reference_b13###]. One-sync variants include, e.g., Tall-Skinny QR (TSQR [10  ###reference_b10###, 11  ###reference_b11###]), also known as AllReduceQR [19  ###reference_b19###], and CholQR [22  ###reference_b22###]. TSQR/AllReduceQR is known to have  LOO, while that of CholQR is bounded by , where  itself should be bounded by .\nIn this manuscript, we focus on reorthogonalized variants of block classical Gram-Schmidt (BCGS  ###reference_###). We begin by proving LOO bounds on BCGS  ###reference_###, which has not been done rigorously before to the best of our knowledge (Section 2  ###reference_###). A key feature of our analysis is an abstract framework that highlights the effects of the projection and intraortho stages. Furthermore, we consider a variant of BCGS  ###reference_### that requires a \u201cstrong\u201d first step (BCGS-A  ###reference_###). Although this modification does not improve the numerical behavior of BCGS  ###reference_###, its reorthogonalized variant BCGSI+A  ###reference_### enjoys  LOO with more relaxed assumptions on the IO than those of Barlow and Smoktunowicz [3  ###reference_b3###] and Barlow [2  ###reference_b2###](BCGSI+  ###reference_###). In Section 3  ###reference_###, we derive a BGS method with one sync point from BCGSI+A  ###reference_###, which is similar to the one-sync variant BCGSI+LS ([9  ###reference_b9###, Algorithm 7] and [24  ###reference_b24###, Figure 3]), and is a block analogue of DCGS2 and CGS-2 with Normalization and Reorthogonalization Lags ([4  ###reference_b4###, Algorithm 2] and [21  ###reference_b21###, Algorithm 3], respectively). Unlike [4  ###reference_b4###, 21  ###reference_b21###], we do not use the notion of lags or delays; instead, we view things in terms of shifting the window of the for-loop, which simplifies the mathematical analysis. We derive the one-sync algorithm in three stages\u2013 BCGSI+A-3S  ###reference_###, BCGSI+A-2S  ###reference_###, and BCGSI+A-1S  ###reference_###\u2013 in order to systematically demonstrate how new floating-point error is introduced with the successive removal of sync points. We then prove stability bounds for these algorithms in Section 4  ###reference_###. A summary and discussion of all the bounds is provided in Section 5  ###reference_###, along with an important corollary: BCGSI+A-1S  ###reference_### achieves  LOO for . In other words, [4  ###reference_b4###, Algorithm 2] and [21  ###reference_b21###, Algorithm 3] are effectively as stable as HouseQR, which thus far has not been rigorously proven. Section 6  ###reference_### concludes our work with an outlook for future directions.\nA few remarks regarding notation are necessary before proceeding. Generally, uppercase Roman letters () denote  block entries of a  matrix, which itself is usually denoted by uppercase Roman script (). A block column of such matrices is denoted with MATLAB indexing:\nFor simplicity, we also abbreviate standard  submatrices as .\nBold uppercase Roman letters (, , ) denote  block vectors, and bold, uppercase Roman script () denotes an indexed concatenation of  such vectors. Standard  submatrices are abbreviated as\nWe will aim for bounds in terms of the induced 2-norm , but we will also make use of the Frobenius norm in the analysis, denoted as . By  we denote the trace of a square matrix . Furthermore, we always take  to mean the 2-norm condition number defined as the ratio between the largest and smallest singular values of ."

+            "text": "It is well known that BCGS  ###reference_### is itself low-sync, in the sense that only 2 sync points are required per block vector, assuming that we only employ IOs that themselves require just one sync point (e.g., TSQR or CholQR). In comparison to block modified Gram-Schmidt (BMGS), which requires  sync points for the th iteration, a fixed number of sync points per iteration can have clear performance benefits; see, e.g., [4  ###reference_b4###, 18  ###reference_b18###, 21  ###reference_b21###, 24  ###reference_b24###].\nWe will consider a slight modification to BCGS  ###reference_### in the first step. We call this variant BCGS-A  ###reference_###, as in Algorithm 1  ###reference_###, where \u201cA\u201d here stands for \u201calpha\u201d or the German \u201cAnfang\u201d, as the key change is made at the beginning of the algorithm. The idea is to require that  be strongly stable like HouseQR and then allow for more flexibility in the IO used in the for-loop.\nUnfortunately, BCGS  ###reference_### (i.e., BCGS-A  ###reference_### with ) can exhibit an LOO worse than , and the situation is no better for BCGS-A  ###reference_###. A natural solution often seen in practice is to run BCGS  ###reference_### twice and combine the for-loops, leading to what we call BCGSI+  ###reference_###, with I+ standing for \u201cinner reorthogonalization\u201d; see Algorithm 2  ###reference_### but assume . BCGSI+  ###reference_### has 4 sync points per iteration and has been analyzed by Barlow and Smoktunowicz [3  ###reference_b3###], who show that as long as the IO has  LOO, then the overall method also has  LOO.\nFigure 1  ###reference_### provides a comparison among BCGS  ###reference_###, BCGS-A  ###reference_### and BCGSI+  ###reference_### for different choices of IOs. All plots in this section are generated by the MATLAB toolbox BlockStab111https://github.com/katlund/BlockStab/releases/tag/v2.1.2024  ###reference_ses/tag/v2.1.2024### in double precision () on what are called monomial 222Each such matrix is a concatenation of  block vectors ,\n, where each  is is randomly generated from the uniform distribution with norm , while  is an  diagonal operator having evenly distributed eigenvalues in . A sequence of such matrices with growing condition number is generated by varying  and ; in particular, , but it is not necessary that  or . matrices; see the script test_roadmap.m. We have used MATLAB 2024a on a Dell laptop running Windows 10 with an 12th Gen Intel Core i7-1270P processor and 32GB of RAM. We use notation like  to denote the composition of the outer block \u201cskeleton\u201d and intraorthogonalizing \u201cmuscle\u201d. We have fixed  for all \u201cA\u201d methods, and only the choice of  is reported in the legends. Note that CholQR is implemented without a fail-safe for violating positive definiteness.333See the chol_free subroutine in BlockStab, based on [15  ###reference_b15###, Algorithm 10.2].\n###table_1### ###figure_1### ###figure_2### It is clear from Figure 1  ###reference_### that BCGSI+  ###reference_### does not exhibit  LOO for . However, by requiring the first block vector to be orthogonalized by something as stable as HouseQR, we can relax the requirement for subsequent IOs and prove a stronger result than in [3  ###reference_b3###]. We denote this modified algorithm BCGSI+A  ###reference_###, given as Algorithm 2  ###reference_###. BCGSI+A  ###reference_### can also be interpreted as a generalization of the BCGSI+F approach introduced in [25  ###reference_b25###].\nThe way Algorithm 2  ###reference_### is written, it would appear that we store three auxiliary matrices  and , where , , and . In practice, the entire matrices need not be stored and built, but their theoretical construction is helpful for proving stability bounds. Further note the three different colors used for different sections of the algorithm: blue for the first BGS step, red for the second, and purple for combining quantities from each step to finalize entries of . These colors may help some readers in Section 3  ###reference_### when we derive variants with fewer sync points.\nFigure 2  ###reference_### demonstrates the improved behavior of BCGSI+A  ###reference_### relative to BCGSI+  ###reference_###. In particular, note that the relative Cholesky residual is restored to  for , indicating that BCGSI+A  ###reference_### returns a reliable Cholesky factor  for a wider range of IOs than BCGSI+  ###reference_###. Practically speaking, BCGSI+A  ###reference_### only needs an expensive (but stable) IO once at the beginning, and less expensive (and even less stable) IOs for the remaining iterations.\n###table_2### ###figure_3### ###figure_4### In the following subsections, we introduce an abstract framework for handling the stability analysis of a general BGS routine by splitting it into projection and intraortho stages. We then prove bounds for BCGS-A  ###reference_### and BCGSI+A  ###reference_### encompassing a wide variety of configurations."

Barlow and Smoktunowicz require that all IOs be as stable as HouseQR. In contrast, Theorem 2  ###reference_orem2### shows that the choice of  has no effect on the LOO of BCGSI+A  ###reference_###, while  only limits the conditioning of  for which we can guarantee  LOO. Recently, Barlow proved a similar result for special cases of BCGSI+A  ###reference_###, where ,  is either HouseQR or a reorthogonalized CholQR, and  [2  ###reference_b2###]. Indeed, Theorem 2  ###reference_orem2### generalizes [2  ###reference_b2###] and reveals additional possibilities that would further reduce the number of sync points. Consider, for example, BCGSI+A  ###reference_### with  and . Such an algorithm would only need 4 sync points per block column, as all IOs need only one global communication, and still achieve  LOO without any additional restriction on .\nUnfortunately, Theorem 2  ###reference_orem2### cannot guarantee stability for  (i.e., ) when , because then .

Ideally, we would like to reduce the sync points to 2 or even 1 per iteration while keeping a small LOO. DCGS2 from [4  ###reference_b4###] boasts both 1 sync point per column as well as  LOO, at least according to their numerical experiments. With an eye towards achieving 1 sync point per block column, we will generalize and adapt their derivation, starting from BCGSI+A  ###reference_###.\nWe can eliminate one sync point by skipping the first normalization step, denoted as  in BCGSI+A  ###reference_###; consequently, we drop the distinction between  and . This leads to BCGSI+A-3S  ###reference_###, summarized as Algorithm 3  ###reference_###; note again the three colors for each phase. Despite the small change\u2013 after all, BCGSI+A-3S  ###reference_### still projects the basis twice and normalizes the projected block vector in step \u2013 the effect on the stability behavior is notable. Figure 4  ###reference_### demonstrates a small LOO when HouseQR is the IO and up to  for when . Furthermore, the relative Cholesky residual of BCGSI+A-3S  ###reference_### begins to increase as well.  in particular cannot handle , due to the Cholesky subroutine being applied to negative semidefinite matrices at some point.\n###table_6### ###figure_7### ###figure_8### BCGSI+A-3S  ###reference_### can also be interpreted as a generalization of the \u201ccontinuous projection\u201d approach introduced in [25  ###reference_b25###] as BCGS-CP. The only real difference is that we allow for stable_qr (i.e., the choice of IO) to differ between the first and subsequent steps, thus adding a little extra flexibility. Zou does not carry out a floating-point analysis of BCGS-CP, which we do in Section 4.1  ###reference_###\nBy fixing the IO to be CholQR for iterations  through  and batching the inner products, we arrive at a 2-sync method, BCGSI+A-2S  ###reference_###, displayed in Algorithm 4  ###reference_###. The block Pythagorean theorem (cf. [8  ###reference_b8###]) could also be used to derive this step, but we take a more straightforward approach here by just expanding the inner product implicit in  (and keeping in mind that we\u2019re still working in exact arithmetic for the derivation). In particular, we find that\nand .\nWe assume that batching itself introduces only  errors for the matrix products, with the exact floating-point error depending on how the hardware and low-level libraries handle matrix-matrix multiplication. In which case, BCGSI+A-2S  ###reference_### can be regarded as equivalent to  in floating-point error.\nDeriving BCGSI+A-1S  ###reference_### (Algorithm 5  ###reference_###) from BCGSI+A-2S  ###reference_### requires shifting the window over which the for-loop iterates. First, we bring out steps 2.1.1 and 2.1.2, which leaves  and  to initialize the for-loop. We then batch all the inner products and define some intermediate quantities  and . Consequently, we cannot compute  directly but rather have to reverse-engineer it from what has been computed in line 5  ###reference_5###:\nBy line 7  ###reference_7###, we have , but not its projection onto , which we cannot get until the next iteration. However, from the same line, we can compute , as it is composed of pieces that can be pulled from line 5  ###reference_5###:\nAfter the loop we have to complete the final step . Interestingly, note that  is no longer needed for the final inner product in line 13  ###reference_13###. We highlight again the colorful chaos of the pseudocode: it helps to illustrate what Bielich et al. [4  ###reference_b4###] and \u015awirodowicz et al. [21  ###reference_b21###] called \u201clagging\u201d, in the sense that \u201cearlier\u201d calculations in blue now take place after the \u201clater\u201d ones in red and purple within the for-loop.\nA comparison of the 3-sync, 2-sync, and 1-sync variants is provided in Figure 5  ###reference_###. BCGSI+A-3S  ###reference_### remains under , while both BCGSI+A-2S  ###reference_### and BCGSI+A-1S  ###reference_### explode dramatically once .\n###table_7### ###figure_9### ###figure_10### This version of 1-sync BCGSI+A  ###reference_### is aesthetically quite different from [9  ###reference_b9###, Algorithm 7] or [24  ###reference_b24###, Figure 3], as well as the column-wise versions of [4  ###reference_b4###] and [21  ###reference_b21###]. For one, a general  is used in the first step. However, the core of the algorithm\u2013 i.e., everything in the for-loop\u2013 is fundamentally the same, up to  rounding errors. Our derivation for BCGSI+A-1S  ###reference_### provides an alternative perspective from just writing out the first few steps of the for-loop, batching the inner products, and reverse-engineering the next column of  from the most recently computed inner product.\nThe monomial example used in Figures 1  ###reference_###-5  ###reference_###\u2013 which are combined in Figure 6  ###reference_###\u2013 paints a pessimistic picture for methods with reduced sync points. The monomial matrices are not especially extreme matrices; they are in fact designed to mimic -step Krylov subspace methods and are built from powers of a well-conditioned operator. There are certainly cases where BCGSI+A-1S  ###reference_### may be good enough; see Figure 7  ###reference_### for comparisons on the default matrices, which are built by explicitly defining a singular value decomposition from diagonal matrices with logarithmically spaced entries. Clearly all methods discussed so far appear more stable than BCGS  ###reference_### on these simple matrices.\n###table_8### ###figure_11### ###figure_12### ###table_9### ###figure_13### ###figure_14### We remind the reader that Figures 1  ###reference_###-7  ###reference_### are all generated by the MATLAB script test_roadmap.m in BlockStab, which we recommend downloading and interacting with for a better understanding of the nuances of these BGS variants."

In particular, the piled matrices are quite tough for BCGS  ###reference_### and BCGS-A  ###reference_###.\n###table_13### ###figure_19### ###figure_20### Despite the rather pessimistic behavior for block variants we have observed, there is yet good news for the column version of BCGSI+A-1S  ###reference_###, i.e., when . Our results apply trivially to the column version and in fact address the open issue of the stability of a one-sync, reorthogonalized CGS, first introduced as [21  ###reference_b21###, Algorithm 3] and revisited as DCGS2 in [4  ###reference_b4###].\nLet  and  denote the computed result of Algorithm 3  ###reference_###, 4  ###reference_###, or 5  ###reference_### with .

Combining this realization with (80  ###reference_###), we obtain\nwith the assumption . Then we use (123  ###reference_3###) instead of Lemma 10  ###reference_ma10###, similarly to the proof of Theorem 3  ###reference_orem3###, to conclude that (121  ###reference_1###) and (122  ###reference_2###) hold for BCGSI+A-3S  ###reference_### with .\nRecalling Section 4.2  ###reference_###, the only difference between BCGSI+A-2S  ###reference_### and  is the estimation of , i.e., , which has been bounded in Lemma 11  ###reference_ma11###.

To enable a uniform approach to our analyses, we introduce an abstract framework which considers the effects of the projection and intraorthogonalization\nstages of a BCGS  ###reference_### method.\nWe first introduce a modification of the basic BCGS  ###reference_### method, called BCGS-A  ###reference_###, in which the IO used for the first block vector can be different than that used for subsequent blocks. We prove a bound on the resulting LOO. As a side effect, this gives the first known bound on the LOO for BCGS  ###reference_### in the literature.\nWe then introduce a reorthogonalized variant of BCGS-A  ###reference_###, BCGSI+A  ###reference_###, and prove a bound on its LOO. Our results reproduce the bound given by Barlow and Smoktunowicz for the case that a single IO is used throughout [3  ###reference_b3###]. Further, our analysis provides a valuable insight: we only need a \u201cstrong\u201d IO on the very first block. After this, less expensive and less stable IOs can be used. The first IO used in the main loop determines the constraint on the condition number of . The second IO, used for the reorthogonalization, has no effect.\nThe resulting BCGSI+A  ###reference_### has four synchronization points. We then demonstrate, through a series of steps, how each sequential removal of a synchronization point affects the LOO and constraints on the condition number for which the bound holds. We eventually reach a low-sync version with only a single synchronization point, equivalent to methods previously proposed in the literature, and we show that unfortunately, the LOO depends on the square of the condition number, which has been conjectured previously in [9  ###reference_b9###].\nDespite the unsatisfactory results for the block variant, our analysis also gives bounds for column (non-block) one-sync variants which have been proposed in the literature [4  ###reference_b4###, 21  ###reference_b21###], and it is shown that these attain a LOO on the level of the unit roundoff.\nIt is still unknown whether there exists a one-sync variant of block Gram-Schmidt with  LOO. One may note that in Theorem 4  ###reference_orem4###, the two-sync variant already has LOO dependent on the square of the condition number, so it is not surprising that this is inherited by the one-sync method. One possible avenue of exploration may be to start with a better two-sync variant (for example, the BCGS-PIPI+ method of [7  ###reference_b7###]) and derive a one-sync variant from this starting point.\nOther possible future directions include the exploration of the effects of mixed precision arithmetic and the analysis of other low-sync variants of BGS, such as BMGS-CWY and BMGS-ICWY; see [9  ###reference_b9###]."

We demonstrate how the robot swarm determines its direction of movement to approach the source using only field intensity measurements taken by each robot. In contrast with the current literature, our algorithm accommodates a generic (non-degenerate) geometry for the swarm\u2019s formation. Additionally, we rigorously show the effectiveness of the algorithm even when the dynamics of the robots are complex, such as a unicycle with constant speed. Not requiring a strict geometry for the swarm significantly enhances its resilience. For example, this allows the swarm to change its size and formation in the presence of obstacles or other real-world factors, including the loss or addition of individuals to the swarm on the fly. For clarity, the article begins by presenting the algorithm for robots with free dynamics. In the second part, we demonstrate the algorithm\u2019s effectiveness even considering non-holonomic dynamics for the robots, using the vector field guidance paradigm. Finally, we verify and validate our algorithm with various numerical simulations.",

In particular, providing formal performance guarantees for an algorithm that is feasible to implement in practice is one of the major challenges in swarm robotics [1  ###reference_b1###]. Effectively solving this problem would significantly impact how we monitor our environment [2  ###reference_b2###], conduct search and rescue operations [3  ###reference_b3###], and detect chemicals, sound sources, or pollutants [4  ###reference_b4###, 5  ###reference_b5###, 6  ###reference_b6###]. One of the key factors that make robot swarms ideal for such missions is their resilience; that is, the ability to maintain functionality even in the presence of adverse and unknown conditions. For instance, a robot swarm can continue operating and locate the source of the field even with the loss of (disposable) robots at any time. Additionally, it possesses unlimited autonomy in time and energy, as robots can enter and leave the swarm as needed.\nIn this work, we propose a resilient algorithm for a robot swarm to solve the problem of source localization in a scalar field. This algorithm is practical for real-world applications for three key reasons: first, the robots only need to make point measurements of the field intensity at their positions; second, we allow for a generic non-degenerate deployment111For example, a degenerate deployment would be forming a line in the plane. within the swarm that can vary arbitrarily; and third, we accommodate realistic restrictive robot dynamics, such as unicycles travelling at constant speed, similar to unmanned aerial vehicles [7  ###reference_b7###].\nSource localization in a field is associated with finding the maximum of a multivariable function, and various approaches to tackle this problem exist in the literature. One of the most common methods is the use of gradient descent techniques. If available, the signal gradient can be used to develop a gradient ascending/descent algorithm for a vehicle or a group of vehicles [8  ###reference_b8###]. However, in practice, robots can only measure the signal magnitude (scalar) and not the gradient (vector). Therefore, it is necessary to use the signal magnitudes in the space to estimate the gradient.\nIn the literature, it is common to require a specific spatial distribution for the robots in the swarm [9  ###reference_b9###, 10  ###reference_b10###, 11  ###reference_b11###], thus restricting their mobility and flexibility. Recently, the authors in [12  ###reference_b12###] proposed an elegant control law where a specific spatial distribution for the robots is not required. However, the swarm\u2019s distribution is not controlled and could be considered chaotic since it changes constantly over time depending on the initial positions of the robots. This can cause problems in certain scenarios, such as the presence of obstacles.\nOur work proposes an alternative to gradient estimation by using an ascending direction to guide the process. By eliminating the need for gradient computation or estimation, the requirement for a specific geometry in robot deployment is removed. This approach allows for dynamic control over the deployment, enabling it to remain constant or adjust arbitrarily, thereby making the robot swarm more flexible and adaptable to real-world demands."

For clarity, we defer the formal proofs of the results to Appendix VI  ###reference_###.\nTo guide the movement of our system, we will draw inspiration from the method of guiding fields, as developed in [15  ###reference_b15###, 16  ###reference_b16###]. However, these methods depend on global knowledge of the field to compute quantities (such as gradients and descent directions) across the entire space. In our case, there are two challenges: first, we do not know the field until it has been explored by the trajectory; second, the field we wish to follow may depend on the geometry of the robot swarm, not just the spatial point of the centroid.\nTo understand the latter, note that Theorem II.4  ###reference_theorem4### provides a field to follow in order to find the maximum, but this ascending direction depends not only on the point  but also on the swarm geometry .\nFor practical purposes, it is convenient to normalize the guiding field. We consider the open set  characterized by  and define  by\nso that . This field will be referred to as the guiding field and is the field we wish to follow to find the maximum.\nIntuitively, to follow the field, the natural approach is to reduce the angle between each robot\u2019s velocity and the direction of the field. To formalize this idea, we need to define new concepts and prove certain preliminary results. We begin by studying the behaviour of the derivative of the guiding field.\nLet  be the guiding field throughout the swarm\u2019s trajectory. Then\nwhere  is a continuous, uniquely determined function and .\nWe introduce the directed angle, , between  and . The function  is defined at any point  where  is defined and is of class  at points where , as depicted in Figure 2  ###reference_###.\n###figure_2### It is straightforward to observe that throughout the trajectory, the change in  will be governed by both the change in  and the variation in the angle subtended by the field . Hence, at any point where  is defined, i.e., where , the following fundamental identity holds\nUsing this relationship, we can address the issue of discontinuities in  within our system by introducing an augmented system that includes the parameter . This leads to the system\nwhere the fundamental identity (8  ###reference_###), together with the initial condition , ensures that the solutions to the augmented system will also give a solution to (2  ###reference_###). Thus, within this new system, we can apply appropriate existence and uniqueness theorems, provided that  is non-degenerate and , since the right-hand side of the system (9  ###reference_###) is locally -Lipschitz in its variables [13  ###reference_b13###, 17  ###reference_b17###].\nNote that the inclusion of the parameter  is purely formal; since we are working in a specific trajectory, this new definition allows us to globally define the oriented angle throughout it, thereby eliminating the pathological discontinuity that occurs when .\nWe aim to ensure that the oriented angle  tends to zero so that the velocities and the guiding field align. The most natural approach to achieve this is to choose a control parameter  that is proportional to  and possibly includes an additional term. Specifically, we can design\nwhere  is a positive constant and  is a parameter that could potentially be chosen. This gives\nHerein lies the challenge compared to traditional methods. If we had global knowledge of the field, we could set , allowing  to decay exponentially to zero. However, since the field is unknown, we cannot determine . There are two possible approaches to address this issue:\nWe could approximate , for example, by using data from previously traversed trajectories or by utilizing multiple nearby robot swarms, enabling us to estimate the field\u2019s distortion from the combined data.\nAlternatively, as we will do in this work, we can disregard the term  (by setting it to zero) and try to bound the value of , such that for sufficiently high values of , exponential decay in  is still achieved.\nNote that seeking to ensure that  is bounded is a natural condition, as this merely means that the field given by  does not change too abruptly. Specifically, we want the angular velocity  to be fast enough to track the changes in the field. Henceforth, we will consider the system (9  ###reference_###) with\nwhere  is a positive constant that will be determined later. With this clarification, we can demonstrate the algorithm\u2019s effectiveness for robots with constant-speed unicycle dynamics, leading to the following convergence result.\nLet  be a signal distribution,  be a swarm with non-degenerate geometry, initial velocity directions , and  fixed. Then there exists a constant  such that for all , the dynamics\nis a solution to the search problem II.3  ###reference_theorem3###.\nSimilar to the case with free dynamics, the field given by (7  ###reference_###) cannot be directly measured by the robots. However, the approximation\nis measurable and suffices in most cases.

More critically, in a sufficiently small neighbourhood around , the angular velocity  changes rapidly, as  undergoes an instantaneous -degree turn when passing through . To address these technical challenges, we restrict our attention to trajectories that avoid such neighbourhoods, ensuring that our robot system ultimately approaches these regions555Which is sufficient, as we are locating a region containing the maximum of our signal., though not controlling the behaviour within them.\nBefore we can provide a bound for , we will need a preliminary result.\nLet  be a trajectory of the system (9  ###reference_###) with a non-degenerate initial geometry .

The fact that the bound on  continues to hold while  is automatic.\n\u220e\nFinally, it is important to note that these technical difficulties have minimal relevance in practical applications and are primarily necessary for formal mathematical treatment. Specifically, conditions such as the non-degeneracy of the geometry , while crucial for theoretical development, are virtually negligible in practical applications. Similarly, bounds on  can be treated as assumptions of favourable behaviour regarding the  field if deemed appropriate. In summary, these technical lemmas justify the intuitive notion that the robots\u2019 angular velocity is sufficiently rapid to effectively follow changes in the field and that once the robots align with the field, their geometry will remain nearly rigid.\nUsing the results previously established, we are now prepared to provide proof of convergence for the system described in (9  ###reference_###), at least up to regions where the gradient is small. Here, the smallness of the gradient is controlled by the value of  that we select.\nWe will show that there exists a value  such that the centroid of the trajectories is confined within the open set\nAs before, we assume without loss of generality that  and  form a basis.

In particular, while the conditions hold, the function  is increasing since\nwhere we have used that  by the previously proven angular relation. Reasoning as in Theorem III.1  ###reference_theorem1###, the magnitude of the field in the trajectory will increase until it enters the set . Once inside, we can no longer control , but we continue to know that  is stable. Thus, if the trajectory escapes from , reasoning as in Lemma VI.5  ###reference_theorem5###, if we take  where  is given by666Technically, one would need to be careful to ensure that the angle is within , this does not constitute a problem, only notational care, since we can always normalize the angles if they fall outside of this interval.

In this paper we focus on the central topic of spectral sparsification of directed graphs, for which, this challenge is particularly manifest.\nA sparsifier of an undirected graph  or directed graph  is another graph supported on the same set of vertices with fewer edges, that approximately preserves some property.\nSeveral notions of sparsification for undirected graphs have been studied in the literature, e.g., spanners [BaswanaS03, ThorupZ05], which approximately preserve shortest path distances, and cut sparsifiers [BenczurK96], which approximately preserve cut sizes.\nSpectral sparsification [SpielmanT04] has been particularly influential in the design of graph algorithms.\nAn -approximate undirected spectral sparsifier (henceforth, -approximate undirected sparsifier)  of undirected  approximately preserves the quadratic form of \u2019s graph Laplacian, i.e., for all\nwhere  and  are the undirected Laplacian matrices of  and  (see Section 2  ###reference_### for notation), and (1  ###reference_###) is equivalent to .\nSpectral sparsification generalizes cut sparsification and was key to the advent of nearly-linear time Laplacian systems solvers [SpielmanT04].\nSimple and efficient algorithms for computing undirected spectral sparsifiers with nearly-optimal guarantees are known.\nSpielman and Srivastava [SpielmanS08] showed that independently sampling (and reweighting)  edges of an -vertex graph, with probability proportional to their effective resistances (a graph-theoretic analog of leverage scores), produces a spectral sparsifier.\nAll effective resistances can be estimated in  time111When discussing a graph clear from context with  vertices and edge weight ratio bounded by , we use the  notation to hide  factors for brevity (in runtimes only). using fast Laplacian system solvers [JambulapatiS21] (see Lemma 13  ###reference_orem13###) \u2013 this step dominates the runtime for undirected spectral sparsification.\nAdditionally, Batson, Spielman, and Srivastava [BatsonSS09] showed spectral sparsifiers with  edges exist, which is optimal [BatsonSS09, CarlsonKST19] and constructible in near-linear time [LeeS17, JambulapatiRT23].\nObtaining correspondingly simple and fast sparsification algorithms and optimal sparsity bounds for directed graphs remains elusive.\nEven proposing useful notions of directed sparsification was challenging; any sparsifier of the complete, directed, bipartite graph, i.e., the graph with a directed edge from every node in one side of the bipartition to the other, that approximately preserves all directed cuts cannot delete any edges.\nThe influential work [CohenKPPRSV17] overcame this bottleneck by restricting their attention to directed Eulerian graphs (where every vertex has equal weighted in-degree and out-degree).\nFurther, [CohenKPPRSV17] showed that their sparsification notion suffices for numerous applications, including fast solvers for all directed Laplacian linear systems (not necessarily corresponding to an Eulerian graph), overviewed in Section 8  ###reference_###. In this paper, we consider the following definition of Eulerian sparsification closely related to that of [CohenKPPRSV17].222The key difference is that we add the  restriction.\nis an -approximate Eulerian sparsifier of  if  and  are both Eulerian, , and for , we have\nDefinition 1  ###reference_orem1### generalizes the notion of undirected sparsification (7  ###reference_orem7###).\nWhile useful in applications, Definition 1  ###reference_orem1### poses computational challenges.\nEulerian sparsifiers preserve exact degree balance, so in contrast to undirected sparsifiers, one cannot simply sample edges independently to compute sparsifiers. There have been two broad approaches for addressing this key challenge.\nThe first approach leverages expander decompositions and is related to one used in [SpielmanT04] to sparsify undirected graphs. [CohenKPPRSV17] followed such an approach and their algorithm consists of decomposing the Eulerian graph  into expanders, sampling edges independently inside the expanders, and then fixing the resulting degree imbalance by adding edges; this resulted in sparsifiers that did not necessarily satisfy the  property in (2  ###reference_###). This approach was refined in [AhmadinejadPPSV23] (using cycle decompositions as in the second approach below, but not necessarily short ones), resulting in an algorithm for constructing Eulerian sparsifiers with  edges in  time.\nExisting near-linear time expander decomposition methods [SaranurakW19, AgassyDK23] incur several logarithmic factors in the running time and (inverse) expansion quality, leading to these large, difficult to improve, polylogarithmic factors in the running time and sparsity.\nThe second approach leverages that most the edges in  can be decomposed into edge-disjoint short cycles, termed a short cycle decomposition. [ChuGPSSW18] pioneered this approach and sampled the edges in a coordinated manner within each cycle to preserve degree balance.\nAdvances in short cycle decompositions [LiuSY19, ParterY19, SachdevaTZ23] resulted in an -time algorithm for constructing Eulerian sparsifiers with  edges.\nShort cycle decompositions yield Eulerian sparsifier constructions with significantly improved sparsity compared to the expander decomposition approach, at the cost of large  factors in running time.\nIn summary, all prior algorithms for constructing Eulerian sparsifiers use either expander decomposition or short cycle decomposition, which result in substantial polylogarithmic factors (or larger) in sparsities and runtimes. More broadly, large gaps seem to remain in our understanding of efficient algorithms for constructing Eulerian sparsifiers and the optimal sparsity achievable."

Moreover, each edge Laplacian only contributes if its leverage score is at most , so  Summing over all edges, the total matrix variance is .\nStopping when  for an appropriate constant, standard matrix concentration bounds then show the total relative spectral error is .\nEmulating such a strategy for Eulerian graphs faces an immediate obstacle: adding and dropping edges independently might result in a non-Eulerian graph, i.e., one that does not satisfy the degree balance constraints of an Eulerian graph. In fact, there may be no setting of  for which the relative change in edge weights, , satisfies the necessary degree balance.\nAs mentioned previously, one approach to Eulerian sparsification [CohenKPPRSV17] independently samples  signs for edges inside an expander, fixes the resulting degree imbalance, and uses the expansion property to bound the resulting error.\nAnother approach, based on short cycle decomposition [ChuGPSSW18], toggles cycles, keeping either only the clockwise or counterclockwise edges, thus ensuring degrees are preserved. Additionally, [AhmadinejadPPSV23] samples  signs for cycles (not necessarily short) inside an expander. Each of these results in large polylogarithmic factors or worse in their guarantees, due to limitations in algorithms for expander or short-cycle decomposition.\nTo obtain faster and simpler algorithms with improved sparsity guarantees, we take an alternative approach. As a starting point, consider sampling a random signing  on edge Laplacians, and projecting  down to the degree balance-preserving subspace. We make the simple, yet crucial, observation: this projection step does not increase the matrix variance (Lemma 17  ###reference_orem17###)! This fact, which lets us bound spectral error as we would if all edge signings were independent, has not been exploited previously for efficient degree balance-preserving sparsification to our knowledge.\nOur second key contribution is recognizing that to bound the variance of an independent edge Laplacian signing in a subgraph, requiring the subgraph to be an expander is stronger than necessary. In Lemma 19  ###reference_orem19###, we show it suffices to work in subgraphs with bounded ER diameter (implied by expansion in high-degree unweighted graphs, cf. Lemma 52  ###reference_orem52###).\nDecomposing a graph into low ER diameter pieces can be achieved more simply, efficiently, and with better parameters (for our purposes) as compared to expander or short cycle decompositions (Proposition 10  ###reference_orem10###).\nTo implement this approach to Eulerian sparsification efficiently, we overcome several additional technical hurdles.\nThe first one is ensuring (in nearly-linear time) that the updated edge weight vector is nonnegative; negative weight edges could occur when projecting a large vector to the degree-preserving space. In previous discrepancy works, e.g., [Rothvoss17], this problem was alleviated by projecting the random vector to the intersection of the subspace with the  hypercube. This projection is expensive; on graphs it could be implemented with oblivious routings, but unfortunately, the fastest routings of sufficient quality in the literature do not run in nearly-linear time. We show that by scaling down the step size by a polylogarithmic factor and appealing to sub-Gaussianity of random projection vectors, we can ensure the nonnegativity of weights.\nSecondly, since the weight updates are small in magnitude, there is no immediate reduction in sparsity.\nUsing a careful two-stage step size schedule (see discussion in Section 7  ###reference_###), we give a potential argument showing that after adding roughly  random signings, each projected by solving an undirected Laplacian system, suffices to make a constant fraction of the weights tiny. These tiny edge weights can then be rounded to zero, decreasing the sparsity by a constant factor.\nCombining our framework with state-of-the-art undirected Laplacian solvers gives our overall runtime of  in Theorem 2  ###reference_orem2###."

Since then, there has been significant work on developing faster undirected Laplacian solvers [KoutisMP10, KoutisMP11, PengS14, CohenKMPPRS14, KyngLPSS16, KyngS16, JambulapatiS21, ForsterGLPSY22, SachdevaZ23], culminating in an algorithm that runs in  time for approximately solving undirected Laplacian linear systems up to expected relative error  (see Proposition 12  ###reference_orem12### for a formal statement).\nThe first spectral sparsifiers for undirected graphs were constructed by Spielman and Teng [SpielmanT04], which incurred significant polylogarithmic overhead in their sparsity. Spielman and Srivastava [SpielmanS08] then gave a simple algorithm for constructing undirected spectral sparsifiers with  edges in nearly-linear time. Batson, Spielman, and Srivastava [BatsonSS09] gave a polynomial time algorithm for constructing undirected spectral sparsifiers with  edges, and established that this sparsity bound is optimal. Faster algorithms for -edge undirected sparsifiers were later given in [LeeS17, LeeS18, JambulapatiRT23]. We also mention an additional notion of sparsification in undirected graphs, degree-preserving sparsification, which has been studied in the literature as an intermediary between undirected and Eulerian sparsification [ChuGPSSW18, JambulapatiRT23]. Degree-preserving undirected sparsifiers of sparsity  were recently shown to exist and be constructible in almost-linear time by [JambulapatiRT23], motivating our work in the related Eulerian sparsification setting.\nThe study of efficient directed Laplacian solvers was initiated by Cohen, Kelner, Peebles, Peng, Sidford, and Vladu [CohenKPPSV16], who established that several computational problems related to random walks on directed graphs can be efficiently reduced to solving linear systems in Eulerian Laplacians. This work also gave an algorithm for solving Eulerian Laplacian linear systems in  time, the first such solver with a runtime faster than that known for linear system solving in general.\nSubsequently, the aforementioned authors and Rao [CohenKPPRSV17] introduced the notion of Eulerian sparsifiers and gave the first -time algorithm for constructing Eulerian sparsifiers with  edges, based on expander decompositions. They used their method to give the first  time algorithm for solving linear systems in directed Eulerian Laplacians. A follow-up work by the aforementioned authors and Kyng [CohenKKPPRSV18] later gave an improved -time solver for directed Laplacian linear systems.\nAs an alternative approach to Eulerian sparsification, Chu, Gao, Peng, Sachdeva, Sawlani, and Wang [ChuGPSSW18] introduced the short cycle decomposition, and used it to give an  time algorithm for computing Eulerian sparsifiers with  edges.\nImproved short cycle decomposition constructions by Liu, Sachdeva, and Yu [LiuSY19], as well as Parter and Yogev [ParterY19] resulted in an improved running time of  for any constant  for the same sparsity.\nVery recently, Sachdeva, Thudi, and Zhao [SachdevaTZ23] gave an improved analysis of the short cycle decomposition-based construction of Eulerian sparsifiers from [ChuGPSSW18], improving the resulting sparsity to  edges. They complemented their algorithmic construction with an existential result showing that Eulerian sparsifiers with  edges exist, using recent progress on the matrix Spencer\u2019s conjecture [BansalJM23]. Our fast algorithm in Theorem 2  ###reference_orem2### yields an improved sparsity compared to the strongest existential result in [SachdevaTZ23] with a significantly improved runtime, and departs from the short cycle decomposition framework followed by that work. Moreover, our existential result in Theorem 4  ###reference_orem4###, which also applies [BansalJM23] (combined with our new framework), improves [SachdevaTZ23]\u2019s existential result by a logarithmic factor.\nFinally, we note that our applications in Section 8  ###reference_### follow from known implications in the literature, e.g., [CohenKPPSV16, AhmadinejadJSS19, PengS22]. In particular, our directed Laplacian linear system solver follows from reductions in [CohenKPPSV16, PengS22], who showed that an efficient Eulerian sparsification algorithm implies efficient solvers for all directed Laplacian linear systems. Building upon this result, our other applications follow [CohenKPPSV16, AhmadinejadJSS19], which show how various other primitives associated with Markov chains can be reduced to solving appropriate directed Laplacian systems.\nThe use of discrepancy-theoretic techniques for spectral sparsification has been carried out in several prior works. First, [ReisR20] showed how to use matrix variance bounds in undirected graphs with the partial coloring framework of [Rothvoss17] to construct linear-sized sparsifiers. Subsequently, this partial coloring-based sparsification algorithm was sped up to run in nearly-linear time by [JambulapatiRT23] and [SachdevaTZ23] showed how to adapt these techniques to the Eulerian sparsification setting, by using an improved analysis of the matrix variance induced by algorithms using short cycle decompositions.\nOur strongest existential sparsification result (cf. Theorems 4  ###reference_orem4###, 26  ###reference_orem26###) follows the discrepancy-based partial coloring approach to sparsification pioneered in these works, combining it with our new matrix variance bounds via ER decomposition (Lemma 19  ###reference_orem19###) instead of short cycles, as was done in [SachdevaTZ23]. Recently, concurrent and independent work of [LauWZ24] gave a derandomized partial colouring framework for spectral sparsification using the \u201cdeterministic discrepancy walk\u201d approach from [PesentiV23], and applied it to obtain polynomial-time deterministic Eulerian sparsifiers satisfying a stronger notion of spectral approximation known as \u201csingular value (SV) approximation\u201d [AhmadinejadPPSV23]. This result of [LauWZ24] complements, but is largely orthogonal to, our results: it yields directed sparsifiers with larger sparsities and runtimes than ours, but which satisfy stronger notions of sparsification (i.e., SV sparsification) and are obtained deterministically."

There are results that have since obtained faster algorithms for computing shortest paths in undirected graphs [Thorup99, DuanMSY23]. Moreover, the shortest paths do not necessarily need to be computed exactly, so it is possible that this factor could be improved as it has been in other region growing settings [MillerPX13, AbrahamN19]. However, since this is not a bottleneck in the runtimes of our main results, we make no attempt to improve it here.\nIn the remainder of this section, we prove Proposition 10  ###reference_orem10###. The algorithm consists of two components. First, we use standard randomized algorithms (Lemma 14  ###reference_orem14###) to efficiently compute an ER overestimate for the graph edges (Definition 11  ###reference_orem11###). Then, we apply a standard result on region growing (Proposition 15  ###reference_orem15###) from [GargVY96] to efficiently partition the edges within one weight range (Lemma 16  ###reference_orem16###). Applying this decomposition scheme at every weight scale to the graph with edge lengths given by the effective resistance overestimates then yields the result.\nInterestingly, the only use of randomization in this algorithm is in computing overestimates of effective resistances and if a sufficiently efficient deterministic subroutine for this was developed, substituting this subroutine into our algorithm would would obtain a deterministic counterpart of Proposition 10  ###reference_orem10###.\nGiven  with , we call  an -approximate effective resistance (ER) overestimate if\nTo efficiently compute ER overestimates for use in our decomposition algorithms, we rely on near-linear time undirected Laplacian linear system solvers. To begin, we first provide a statement of the current fastest Laplacian linear system solver in the literature.\nLet  be the Laplacian of . There is an algorithm which takes , , and , and outputs  such that with probability ,  is an -approximate solution to , i.e.,\nin time . Moreover, the algorithm returns  where  is a random linear operator constructed independently of , such that the above guarantee holds with  for all .\nThe runtime guarantee of the above proposition follows from Theorem 1.6 of [JambulapatiS21]. We now briefly justify the second clause in Proposition 12  ###reference_orem12###, i.e. that the Laplacian solver is a randomized linear function of , as it is not explicitly stated in [JambulapatiS21]. Theorem 1.6 follows by combining an algorithm which constructs low-stretch subgraphs with a recursive preconditioning framework (Algorithm 12). Algorithm 12 returns the result of an error-robust accelerated gradient descent procedure , which only applies linear transformations and a procedure , to . In turn,  performs only linear transformations and another procedure  to its input. Finally,  applies linear transformations and Algorithm 12 to its input: in addition, these calls to Algorithm 12 operate on strictly smaller problems. Thus, if we assume that these inner calls to Algorithm 12 perform a linear transformation of , the outer call is also a linear transformation: the last claim in Proposition 12  ###reference_orem12### follows.\nProposition 12  ###reference_orem12### combined with a Johnson-Lindenstrauss based sketching approach from [SpielmanS08] shows we can efficiently approximate a set of effective resistances to constant multiplicative error, which we summarize in the following. We remark that the runtime in [SpielmanS08] is larger than in Lemma 13  ###reference_orem13###; our improvement stems from replacing the solver used there with Proposition 12  ###reference_orem12###.\nLet , let  be the Laplacian of , and let .

We output the median of  independent evaluations of\nfor  filled with random scaled Gaussian entries, and where  is the random linear operator given by the approximate solver in Proposition 12  ###reference_orem12### with a sufficiently small constant .

For each independent run , we first precompute  in the given time, and apply  from Proposition 12  ###reference_orem12### to each of the  rows of this matrix. Notably, we can reuse the same random seed in the solver of [JambulapatiS21] so that the random linear operator  provided by Proposition 12  ###reference_orem12### is the same for all rows of .

This is clear for\nRounding and Algorithm 2  ###reference_thm2### to 2  ###reference_thm2###. The most computationally intensive\nstep is Algorithm 2  ###reference_thm2###, which consists of finding a subspace of large\nGaussian measure and solving a convex program.\nThe latter is polynomial time [GrotschelLS88]; the former is due to intersecting the explicit subspace from Algorithm 2  ###reference_thm2### and the subspace from Proposition 20  ###reference_orem20###.\nThe subspace from Proposition 20  ###reference_orem20### is explicitly described in the proof of Lemma 3.1 of [BansalJM23]; it is an eigenspace of a flattened second moment matrix.\nAll steps are deterministic except for the use of Corollary 22  ###reference_orem22### in Line 2  ###reference_thm2### (note that we can bypass Lemma 13  ###reference_orem13### via exact linear algebra computations). This line succeeds with probability  for a random draw. Finally, we can boost this line to have failure probability  by running  independent trials, as we can verify whether a run succeeds in  time.\n\u220e\nWe are now ready to state and analyze our overall sparsification algorithm, ExistentialSparsify (Algorithm 3  ###reference_thm3###). The following is a refined version of Theorem 4  ###reference_orem4###.\nGiven Eulerian  with , ,  and , ExistentialSparsify (Algorithm 3  ###reference_thm3###) returns Eulerian  such that  is an -approximate Eulerian sparsifier of , and\nExistentialSparsify succeeds with probability  and runs in time .\nRecall from Section 2  ###reference_### that we assume without loss of generality that  is connected. Throughout, condition on the event that all of the at most  calls to\nERDecomp succeed, which happens with probability .\nBecause ExistentialDecompSparsify guarantees that no weight grows by more than a  factor in each call,  is a valid upper bound for the maximum weight of any edge throughout the algorithm\u2019s execution.\nMoreover, since no weight falls below  throughout by\nExistentialDecompSparsify,  is an upper bound\non the number of decomposition pieces ever returned by ERDecomp, by\nProposition 10  ###reference_orem10###.\nNext, note that under the given lower bound on  in a given\niteration (which is larger than ), the sparsity progress\nguarantee in Item 3  ###reference_i3### of Lemma 25  ###reference_orem25### shows that the number of\nedges in each iteration is decreasing by at least a  factor until termination.\nSince  and the algorithm terminates before reaching  edges,  is\na valid upper bound on the number of iterations before the second condition in\nAlgorithm 3  ###reference_thm3### fails to hold, which gives the sparsity claim.\nLet .\nTo prove the spectral error bound, we show by induction that until the algorithm\nterminates, the following conditions hold, where we use  to denote the number\nof times the while loop runs in total:\n\n.\n\nNote that Items 1  ###reference_i1###, 2  ###reference_i2### and 3  ###reference_i3### all hold trivially for .

Consequently,  has the same connected components as the original graph , i.e., since we assumed  is connected, so is .\nHence, 8  ###reference_orem8### implies that\nThis proves Item 3  ###reference_i3### in the inductive hypothesis, as desired, and also implies that after the  loop,\nThe sparsity bound follows by explicitly removing any  where  from .\nIn light of Lemma 25  ###reference_orem25###, we note that each of the  calls to ExistentialSparsify can be implemented in  time, and all steps of Algorithm 3  ###reference_thm3### other than ExistentialDecompSparsify run in linear time. We adjust the failure probability by a  factor to account for the multiple uses of Corollary 22  ###reference_orem22### via a union bound, giving the claim.\n\u220e\nTheorem 4  ###reference_orem4### is one logarithmic factor in  away from being optimal, up to low-order terms in . The extra logarithmic factor is due to the parameters of our ER decomposition in Proposition 10  ###reference_orem10###, and the low-order terms come from the additive terms with polylogarithmic overhead in Proposition 20  ###reference_orem20###. In Appendix C  ###reference_###, we discuss routes towards removing this overhead, and relate them to known results and open problems in the literature on graph decomposition (i.e., the [AlevALG18] decomposition scheme) and matrix discrepancy (i.e., the matrix Spencer conjecture)."

We then apply Rounding to fully sparsify these edge weights, incurring small spectral error.

In each loop of Lines 5  ###reference_thm5### to 5  ###reference_thm5###, the algorithm terminates if either a constant fraction of edge weights in  have decreased by an  factor compared to , or a certain potential function bounding the change in weights has decreased significantly. Moreover, each reweighting adds a circulation (and hence preserves degrees), while maintaining that  is unchanged, up to an inverse-polynomial approximation error due to our subroutine ProjMinusRankOne. The algorithm simply iterates this loop until termination. We now analyze Algorithm 5  ###reference_thm5###, by bounding the spectral error and showing that each loop of Lines 5  ###reference_thm5### to 5  ###reference_thm5### is likely to terminate.\nThere is a universal constant  such that if , where\nBasicFastSparsify (Algorithm 5  ###reference_thm5###) returns  satisfying, with probability :\nand .\nfor all .\nEither , or\n.\n, where .\nThe runtime of BasicFastSparsify is, for  where ,555The polyloglog factors hidden by the  notation will be  factors where  is the edge weight ratio of the original graph we sparsify in Section 7.4  ###reference_###, as discussed in that section.\nLet . Because the algorithm continues looping Lines 5  ###reference_thm5### to 5  ###reference_thm5### until the condition in Item 3  ###reference_i3### is met, the conclusion that Item 3  ###reference_i3### holds is immediate.\nThe remainder of the proof proceeds as follows. We first prove the runtime claim by giving a constant lower bound on the probability a single run of Lines 5  ###reference_thm5### to 5  ###reference_thm5### ever fails to enter the else branch on Line 5  ###reference_thm5###, assuming for simplicity that all calls to ProjMinusRankOne are exact, i.e., that every time Line 5  ###reference_thm5### is run,\nWe next prove that Items 1  ###reference_i1###, 2  ###reference_i2###, and 4  ###reference_i4### hold with the requisite failure probability. Finally, we modify the argument to handle approximation error due to inexactness in Line 5  ###reference_thm5###.\nOur goal in this part of the proof is to establish that each run of Lines 5  ###reference_thm5### to 5  ###reference_thm5### results in the else branch on Line 5  ###reference_thm5### being entered with probability . We use this claim to obtain our runtime bound. In the following discussion, fix a single run of Lines 5  ###reference_thm5### to 5  ###reference_thm5###. We let  denote the event that  conditioned on the randomness of all iterations .\nWe also let  denote the event that the algorithm enters the if branch on Line 5  ###reference_thm5### on iteration , and\nwhere both definitions in (20  ###reference_###) are taken with respect to all randomness used in the current run of Lines 5  ###reference_thm5### to 5  ###reference_thm5###. In other words,  is the probability the algorithm has not entered the else branch on Line 5  ###reference_thm5### in any iteration , and  is an expected potential function tracking edge weights over iterations , both conditioned on  occurring. Also, note that by Lemma 31  ###reference_orem31###, , so . Thus, if we can show , we have our goal:\nSuppose for contradiction that , so that  for all . First, we compute, following the convention that  if  or we run the else branch in iteration ,\nThe second line used the approximation  for , the third line used that no weight changes if we enter the else branch, and the last line used our assumption .\nWe next upper bound the right-hand side of (22  ###reference_###). Observe that the definition of  (assuming (19  ###reference_###)) ensures  using Lemma 27  ###reference_orem27###, so  in every iteration.\nSince any  due to  must have , and , there can be at most  such edges. Similarly, at most  edges  can have , so  throughout the algorithm. Hence under , which also implies , we always have . Moreover, note that since  for Rademacher ,\nHowever, note that the dimension of the subspace spanned by  is at least\nunder the assumption ,\nsince it has  degree constraints and one orthogonality constraint to .\nWe now handle conditioning on the event , which satisfies . Combining (23  ###reference_###) with the above, and using that each  is -sub-Gaussian (Lemma 31  ###reference_orem31###) and the set of  satisfying  is closed under negation, applying Lemma 32  ###reference_orem32### shows\nTherefore, combining with (22  ###reference_###) shows that  decreases by at least  for each of the first  iterations. However, we also have that with probability ,\nThis is because the algorithm freezes the weights  as soon as , and the potential can only change by  in an iteration  assuming , since then  entrywise for . This is a contradiction since  (indeed, we choose  larger by a constant factor to account for inexactness in ProjMinusRankOne later), so  as claimed.\nThe runtime follows from Lemma 29  ###reference_orem29###, as the number of runs of Lines 5  ###reference_thm5### to 5  ###reference_thm5### is  for .\nWe have shown that with probability , Lines 5  ###reference_thm5### to 5  ###reference_thm5### terminate after\nloops. Conditional on this event and following our earlier notation, the probability of  all occurring in each of the at most  loops is at least  by our choice of  and Lemma 31  ###reference_orem31###. Under these events (i.e. that there are at most  loops and all  are small), Item 2  ###reference_i2### is immediate, since edges  with  are removed from consideration in a current iteration , and no edge weight changes by more than a  factor multiplicatively. Also, assuming (19  ###reference_###), Item 1  ###reference_i1### is also immediate (we will analyze the inexactness tolerance later).\nWe now prove Item 4  ###reference_i4###. For all , let  and let . We assumed that  was a -cluster in , and no entry of  restricted to  is larger than  by definition of , so\nHere we used that  for all  by assumption. By applying Lemma 19  ###reference_orem19### for all iterations  to the sequence of matrices  in (11  ###reference_###) for , we inductively apply Lemma 30  ###reference_orem30### to show that with probability , on any of the  runs of Lines 5  ###reference_thm5### to 5  ###reference_thm5###,\nThere are a few subtleties in the above calculation. First, observe that Lemma 19  ###reference_orem19### implies that if the  are defined with respect to  rather than  (as in Algorithm 5  ###reference_thm5###), the variance bound still holds, because Lemma 17  ###reference_orem17### applies to  as well. Second, inductively using the guarantee above with Fact 7  ###reference_orem7### shows that  for all iterations , where we used the assumption on  for a large enough choice of , so we adjusted the right-hand side by a constant factor. Third, note that the above argument holds with probability  for each of the  runs of Lines 5  ###reference_thm5### to 5  ###reference_thm5###, so it holds with probability  for all of them by a union bound.\nFinally, we need to condition on all  holding in all loops. We give a simple argument which removes this conditioning. If any  fails, we set all future weight updates to zero. Therefore, regardless of whether the  occur, the matrix variance (17  ###reference_###) in our application of Lemma 30  ###reference_orem30### is bounded as we claimed. In particular, in an iteration , as long as no  has occured for , Lemma 19  ###reference_orem19### holds, and if any have occured, the variance is trivially bounded by .\nThe overall failure probability of  comes from union bounding on the three events we have conditioned on so far (finishing in  loops, all  holding in all loops, Item 4  ###reference_i4### holding), and the event that all of the  executions of Line 5  ###reference_thm5### succeeed, which occurs with probability .\nIt remains to discuss the effect of replacing our exact projections with our approximation through ProjMinusRankOne. Because we ensured , the first bound in (16  ###reference_###) shows that entrywise  is not affected by more than  by approximation, so accounting for slack in our earlier argument Item 2  ###reference_i2### remains true. Next, using\nwe have by  that the approximation negligibly affects the argument in (24  ###reference_###), which we accommodated in the constant factors in , so it is still the case that Lines 5  ###reference_thm5### to 5  ###reference_thm5### terminate with probability  in each loop. Regarding Item 1  ###reference_i1###, note that\nin each iteration after applying the degree fixing in Line 5  ###reference_thm5###, so the invariant on degrees holds as claimed. The bound , combined with the last claim in (16  ###reference_###) and , shows the  norm of the weights cannot grow by more than  throughout. Moreover, the assumption  with the second guarantee in (16  ###reference_###) shows that in each iteration, the total degree imbalance , and the error vector  (in the context of Lemma 24  ###reference_orem24###) satisfies . Lemma 24  ###reference_orem24### then shows that . The last two guarantees in Lemma 24  ###reference_orem24### combined with the triangle inequality show that in each iteration, the additional spectral error due to approximate solves is , and the additional error due to rounding is \ngiving the additional spectral error term in Item 4  ###reference_i4### after accumulating over all iterations. Finally, the runtime follows directly from Lemma 24  ###reference_orem24### (for computing ), and Lemma 29  ###reference_orem29###.\n\u220e\nWe provide one additional result which helps in disjoint applications of BasicFastSparsify.\nConsider calling BasicFastSparsify  times, with shared parameters , but on edge-disjoint subgraphs  through , so that the corresponding  are all -clusters in  for some value of . Then with probability , the total operator norm error (i.e., Item 4  ###reference_i4###) incurred by all calls is bounded by\nThe claim is that we do not incur an  factor overhead in the operator norm error on the first term in the spectral error, and also do not incur an  factor overhead on the  term in the runtime. Note that the bound came from combining the variance bound in Lemma 19  ###reference_orem19### with the high-probability guarantee in Lemma 30  ###reference_orem30###. By treating each of the at most  reweightings applied by Algorithm 5  ###reference_thm5### in parallel across the edge-disjoint clusters, the combined variance in the sense of Lemma 19  ###reference_orem19###, where  is set to the union of all clusters, is still bounded. The failure probability is by a union bound over  calls. For the runtime, note that we can compute the degree imbalances in Line 5  ###reference_thm5### for all clusters simultaneously, and route them on  in time  per iteration.\n\u220e"

Observe that we have  in the first  calls to BasicFastSparsify for each cluster (in Lines 6  ###reference_thm6### to 6  ###reference_thm6###), and  in the last  calls (in Lines 6  ###reference_thm6### to 6  ###reference_thm6###). Therefore, taking note of Corollary 35  ###reference_orem35### and since , the spectral error in all intermediate iterations across all decomposition pieces is bounded by\nAdditionally, there is an  additive error term which comes from Corollary 35  ###reference_orem35###, which is bounded by  after accounting for the change in the graph Laplacian (i.e., by Fact 8  ###reference_orem8###).\nFor appropriate , this both proves the desired spectral error bound by the triangle inequality, as well as the claimed  throughout the algorithm by Fact 7  ###reference_orem7###, which again implies that  is connected under our assumption that  is connected (see discussion in Section 2  ###reference_###). Finally, applying Rounding incurs at most  spectral error through the final graph by Lemma 24  ###reference_orem24###, which is at most  spectral error through the original graph by Fact 8  ###reference_orem8###. The guarantee on the weight increase is clear as we only modify weights within clusters, and Item 2  ###reference_i2### of Lemma 34  ###reference_orem34### shows no edge weight grows by more than a factor of . This concludes the correctness proof.\nFor the runtime, the total number of times we call BasicFastSparsify on each piece of the ER decomposition is . Thus, Lemma 36  ###reference_orem36### shows that with probability , the number of times Lines 5  ###reference_thm5### to 5  ###reference_thm5### runs is , for all decomposition pieces simultaneously. This gives the first term in the runtime via Lemma 34  ###reference_orem34###, as all decomposition pieces have disjoint edges. For the second term in the runtime, it suffices to note that Lines 5  ###reference_thm5### to 5  ###reference_thm5### can be applied in parallel (after summing the degree imbalances  in Line 5  ###reference_thm5###) for all decomposition pieces which terminate in a given run of Lines 5  ###reference_thm5### to 5  ###reference_thm5###, so we do not pay a multiplicative overhead of  on the runtime of Lemma 24  ###reference_orem24###.

+            "text": "Virtually all current robotic systems are interconnected through computer networks for exchanging sensor measurements, control commands, and other information for monitoring and controlling purposes [1  ###reference_b1###]. Mobile robots are examples of such systems and have become integral to a broad spectrum of applications, particularly in scenarios where human intervention is either impractical or inefficient. These applications range from industrial automation and logistics, where mobile robots handle materials, to exploration and data collection in hazardous environments such as deep-sea locations, disaster sites, and space missions [2  ###reference_b2###].\nGiven the increasing reliance on mobile robots for critical tasks and their operation in potentially unsecured or remote environments, ensuring the robustness of these systems against cyberattacks is an important area of research [3  ###reference_b3###].\nThe operation of these mobile robots often relies on networked communication systems to receive commands and transmit data back to the operators or control servers. This networked nature, while enabling remote and autonomous operations, is also susceptible to cybersecurity threats. One significant threat is False Data Injection Attacks (FDIAs)[4  ###reference_b4###, 3  ###reference_b3###, 5  ###reference_b5###], where an attacker manipulates the data being sent to or from the robot, or both, leading to incorrect actions, decision-making based on false information, or even taking control of the robot\u2019s operations.\nFor instance, in an FDIA, the data regarding the robot\u2019s location or sensor measurements could be compromised, misleading the navigation system and causing the robot to deviate from its intended path. In more sophisticated scenarios, as shown in Fig. 1  ###reference_###, attackers could inject false data to make the robot\u2019s system believe it is operating normally, referred to as undetectable or stealthy FDIAs [6  ###reference_b6###, 7  ###reference_b7###], while it performs unintended tasks or causes physical damage to its surroundings.\n###figure_1### Stealthy and undetectable attacks are characterized by their increased difficulty for operators to detect.\nIn stealthy attacks, an attacker capable of intercepting the original messages can inject the attack with partial or no knowledge of the plant, ensuring that the changes remain below the threshold of an attack detector [6  ###reference_b6###].\nIn the case of an undetectable attack, the attacked signals coincide with those that are within the regular operating range, causing faults and standard detectors to fail [8  ###reference_b8###]. Perfectly undetectable attacks are those where there is no change in observed states, yet data integrity has been compromised.\nSimilar attacks to those introduced in this paper have been discussed as covert attacks, as proposed in [9  ###reference_b9###], whereby if the attacker has perfect knowledge of the plant, it is possible to mask the attack from the controller\u2019s perspective.\nMost works on covert attacks address linear time invariant [9  ###reference_b9###, 4  ###reference_b4###, 8  ###reference_b8###, 10  ###reference_b10###] systems.\nFDIA attacks have been implemented to systems with moderate nonlinearities [11  ###reference_b11###].\nIn this case the a simplified linearized version of the actual dynamics is used for the basis of the attack.\nOther considerations of non-stealthy FDIA to nonlinear systems have been made to a class of nonlinear systems [12  ###reference_b12###].\nIn contrast, this paper specifically discusses perfectly undetectable FDIA applied to nonlinear mobile robot dynamics.\nThe robustness of closed-loop systems to account for uncertainties, disturbances, and sensor noise is a well-established and extensively studied field of research.\nCommon compensation strategies from the control-theoretical standpoint include robust optimal control [13  ###reference_b13###], adaptive control[14  ###reference_b14###], state and disturbance compensation[15  ###reference_b15###].\nFor anomaly detection associated with FDIA, a specific strategy involves a model-based control approach: the controller compares the observed plant behaviors induced by its control commands with those simulated based on a nominal plant dynamic model [8  ###reference_b8###, 7  ###reference_b7###, 6  ###reference_b6###]. Any discrepancies identified through this process could indicate potential false-data injection, disturbances, or plant uncertainties.\nEncrypting communication lines or control algorithms [16  ###reference_b16###, 17  ###reference_b17###] adds another layer of protection. However, malleability of homomorphic encryption schemes can be exploited to apply FDIA [18  ###reference_b18###, 19  ###reference_b19###].\nConversely, if the controller observes little (i.e., stealthy) or no changes (i.e., perfectly undetectable) in the plant dynamics between normal and attacked states, model-based anomaly detection would be ineffective [9  ###reference_b9###, 20  ###reference_b20###, 21  ###reference_b21###, 22  ###reference_b22###]. Perfectly undetectable attacks are those in which there are no changes in the observed states, even though the closed-loop system is under attack and performs unintended motions.\nThe significance of this paper lies in the formulation of a generalized FDIA that involves coordinated multiplicative and additive data injections on both control commands and observables, taking form of affine transformations. Unlike covert attacks that require extensive computation and manipulation of the closed-loop system with complete knowledge of the plant dynamics [22  ###reference_b22###], this relatively simplistic and static FDIA allows attackers to execute perfectly undetectable attacks on remotely controlled mobile robots.\nEmploying a classical two-wheel mobile robot kinematic model as a case study, this paper demonstrates how the inherent structure of commonly used nonlinear robot dynamics, from commands to outputs, enables a range of perfectly undetectable FDIAs. This vulnerability persists regardless of the type of trajectory control (e.g., [23  ###reference_b23###]), resulting in undetected failures within the controller\u2019s attack detection algorithms.\nAs a countermeasure, the paper proposes a state monitoring signature function (SMSF) approach along with an associated implementation architecture to continuously monitor for indications of perfectly undetectable FDIAs.\nA signature function can be constructed from polynomial functions that are resilient to scaling and reflection attacks. While not permanently secure, the signature function can be designed to be difficult for the attacker to adversarially estimate for spoofing attacks. The SMSF approach differs from hash functions [24  ###reference_b24###] and auxiliary systems [22  ###reference_b22###]. SMSF operates on continuous and dynamic system states rather than static data as employed in hash functions. Additionally, SMSF can be implemented as a fully software solution, avoiding the need for an additional dynamic component often required by auxiliary systems.\nThis paper is organized as follows:\nSection II  ###reference_### provides preliminaries on well-known mobile robot dynamics and representative trajectory control methods. Section III  ###reference_### discusses perfectly undetectable FDIA on nonlinear control systems and introduces affine transformation-based formulations. Section IV  ###reference_### offers two solutions to the perfectly undetectable FDIA problem. Section IV-C  ###reference_### analyzes the stability of the closed-loop system under perfectly undetectable FDIA. Section V  ###reference_### presents experimental results. Section VI  ###reference_### introduces a SMSF as a countermeasure to perfectly undetectable FDIAs. While promising, this method has its own limitations.\nSection VII  ###reference_### discusses key observations and limitations, and Section VIII  ###reference_### provides concluding remarks."

The attacker can introduce a FDIA that multiplies the output of the signature function by the square of the scaling factor, rendering the attack undetectable.\nAlso, this candidate function only concerns the distance from the origin  exhibits radial symmetry about the origin and therefore deemed inappropriate.\nWithout loss of generality, we can consider constructing a monitoring signature that is a) positive definite (taking 0 only at the origin) to detect linear translation attacks by , b) non-invariant under scaling and lacking symmetry to detect scaling and reflections by . Although guaranteeing the detection of general affine transformations is challenging, roughly speaking, c) having asymmetric contours (or level sets) would be necessary. Below, a polynomial function of the state variables is considered as a candidate signature function, constructed according to the following design guidelines.\nUse even-powered terms (with at least two different powers) to ensure non-negativity and avoid homogeneity of any specific degree. Unlike Lyapunov or \u201cLyapunov-like\u201d functions used in the literature, the negative (semi) definiteness of the derivative of the function is not strictly necessary for monitoring purposes.\nIncorporate odd-powered terms to ensure that sign flips (e.g.,  and ) compute differently. Note that odd-powered terms must be introduced as a part of even-powered terms to ensure non-negativity.\nInclude coupled terms between different variables to introduce asymmetry (e.g., ). Note that these asymmetries must be sufficiently nonlinear to prevent reversal through a linear transformation.\nConsider a candidate signature function that involves two variables  and  and extends up to the quartic degree. According to Requirement 1,  must be included. According to Requirements 2 and 3, some (or all) terms like  should be included. For those reasons, functions of only up to the quadratic degree are not suitable.\nNote that one of the state variables  is not used for simplicity. While  is positive semi-definite in this case, because the attacker is not able to implement a pure rotation attack about the initial position along a trajectory, this property does not impact the ability of state monitoring.\nRemark 6: Constructing more complex signature functions. To enhance resilience against estimation attacks, one can consider incorporating a variety of mathematical constructs beyond simple polynomials. These can include exponential functions for rapid non-linear growth, trigonometric functions for periodic behavior, discontinuous functions for abrupt changes, composite functions combining different types, piecewise functions with region-specific behaviors, and recursive functions for iterative complexity. When constructing such functions, we should balance complexity with computational efficiency.\nAs another attack scenario, an intelligent attacker can estimate the signature function through regression to fully reproduce  and completely alter the signal to align with , as shown in Fig. 13  ###reference_###, making the attack remain undetectable.\nThis implies that the SMSF remains secure only until an attacker, who can intercept the state variables  and , fully estimates the function, and the security may be quantified by its sampling complexity. The state monitoring approach will lose all effectiveness immediately if  is fully known by the attacker.\nWhen implementing the SMSF approach, it is assumed that the structure of the function, such as being a polynomial function of the state variables and its degree, may be known. However, the coefficients are not known at the beginning of system operation. It is safe to change the coefficients before each system operation as a \u2019moving target\u2019. However, the coefficients remain fixed during each operation, as changing them would require additional communication between the controller and plant that may be intercepted.\nmay be estimated by using polynomial regression (PR), Gaussian Process Regression (GPR), Neural Network (NN) regression or other alternatives.\nThe VC dimension [30  ###reference_b30###] of  is a reasonable starting point for estimation. However, this should be considered a minimum guideline; more samples may be beneficial for robust estimation, particularly in complex regions of the function domain. The sample complexity [31  ###reference_b31###, 32  ###reference_b32###], which quantifies the number of examples needed to learn a function to a given accuracy, increases with the VC dimension and the desired precision of the estimate. In practice, the required number of samples can be significantly higher than this lower bound, especially for complex, nonlinear functions. As demonstrated in the illustrative example below, the estimation of  only from intercepted samples along the realized trajectory is much more challenging for the attacker, further increasing the effective sample complexity.\nDefinition 2: Security of state monitoring along a trajectory against adversarial estimation\nLet  be the function estimated by the attacker using  intercepted samples  collected along the trajectory from  to the current time, where .\nThe security of the SMSF is maintained if:\nwhere  is the relevant state space. If this condition holds, the attacker cannot alter  being sent from the plant to the controller below a threshold  throughout the state space, and therefore any attack can be detected by the controller.\nRemark 7.\nAs an additional security measure, it is recommended to encrypt  and evaluate it using methods such as homomorphic encryption applicable to real-time control [33  ###reference_b33###]. It is expected that the security of the signature function improves in accordance with the sample complexity in both the cryptosystem and the target plant dynamic model [32  ###reference_b32###]. However, note that the application of encryption does not fully prevent the risk of signature function estimation.\n###figure_13###"

As representative regression techniques, polynomial regression (PR) and Gaussian process regression (GPR), are applied. For PR, it is plausible to assume that the attacker knows the degree of the polynomial, and thus all the polynomial bases are known. The estimation is then performed to identify the coefficients.\nThe main challenge for the attacker lies in their ability to estimate  (denoted as ) by intercepting the attacked trajectory , with sufficient accuracy to reproduce . The success of this adversarial estimation and reproduction is critical, as it makes the state monitoring process based on  fully ineffective.\nSince the VC dimension of (84  ###reference_###) is 15, seeing if using 150 sample points (15  10) to for 3 seconds, following the heuristic of using about 10 times the VC dimension.\nHere, the attacker is assumed to eavesdrop for the first 3 seconds () for each of the operations, and then uses the acquired  to predict the following values.\nIn this instance the attacker allows the controller to monitor  till \nIn this instance, the attacker used a sample limited to the trajectory, leading to poorer estimations.\nFig. 15  ###reference_### shows the comparison between  and  over time.\nAs the sample is not distributed evenly within the workspace, only along the realized trajectories, the estimation fails, and the security of the monitoring approach is maintained.\n###figure_15### ###figure_16### ###figure_17### From the attacker\u2019s perspective, there may be two potential attempts to improve the performance of : 1) increased number of samples, and 2) a trajectory that provides a wider coverage of the workspace.\nThis allows for a bigger window for the controller to detect the presence of an FDIA before  can be estimated.\nFig. 16  ###reference_### shows the performance of the estimation with increased numbers of samples for regression.\nFor the first 500 samples, the experimental data from Section V  ###reference_### was used, followed by the data generated by simulation.\nNormalized root mean square error (NRMSE) is shown as the metric of fitness.\nIn general, increasing the number of samples improved the performance of estimation. Nevertheless, neither of the attack scenarios provides perfect estimation, probably due to insufficient coverage of the workspace along the attacked trajectories.\nIf the user operates the robot along a trajectory that widely explores the workspace, the attacker would collect a sufficiently rich dataset. Fig. 17  ###reference_### shows the performance of polynomial regression performed with data from a fictitious spiraling trajectory simulated up to 1000 samples. With a sample size of 150, the recommended sample size based on the VC dimension, the estimation result was significantly better compared to the previously considered sinusoidal trajectory with a NRMSE of only 0.26. The distribution of samples was observed to be the main factor for successful estimation. It is understandable that estimation of the signature function is eventually achieved by the attacker, indicating the necessity of frequent updates of the function."

Preexisting discussions of deceptive and undetectable attacks are often limited, with strong assumptions restraining the attacker\u2019s capability and focusing on simple systems [9  ###reference_b9###, 22  ###reference_b22###]. However, even without conditions such as full knowledge of system dynamics or linearity, substantial attacks could be applied to systems.\nThe mobile robot tracking control experiment in this paper demonstrates that for an attacker capable of compromising both legs of a networked control system, the only information required by the attacker was the structure of the Jacobian  and initial conditions, unlike covert attacks that necessitate perfect knowledge of the plant dynamics. In the studies by Zhai et al. [34  ###reference_b34###] and Sandberg et al. [6  ###reference_b6###], the realization of covert attacks is formulated as an optimization problem using the plant dynamic model. These studies allow for control-theoretic discussion and are thus of academic interest, but their implementation may be challenging from an engineering perspective.\nIn contrast, affine transformation seems to be a more practical attack method. Relatively simplistic attacks with constant attack parameters, which do not alter the degree of the closed-loop dynamics, were effective to significantly modify the robot\u2019s behavior while remaining undetectable from the controller\u2019s perspective.\nThe affine transformation-based FDIAs are highly effective on multi-dimensional robotic systems rather than low-dimensional systems but with high degree. By manipulating variables of the same physical quantities through operations such as scaling or reflection, attackers can significantly alter a robot\u2019s behavior while maintaining mathematical consistency. This attack exploits the multi-dimensional nature of robotic systems, making attacks difficult or impossible to detect yet simple to implement, even with partial system knowledge. The preservation of mathematical structures in these multi-dimensional spaces poses significant challenges for traditional detection methods.\nRegarding electronic watermarking [35  ###reference_b35###], even if white noise is added at the controller, the observed dynamics remain unchanged as shown in (29  ###reference_###), so the effect of white noise will be accurately restored on the observation side. This means that the covariance of the estimation error by the observer does not change, making existing watermarking methods ineffective.\nNote that the existence of perfectly undetectable FDIA is guaranteed for linear plants [10  ###reference_b10###] but not necessarily for all nonlinear dynamic systems. While Proposition 1 provides a general framework for nonlinear dynamics in affine form, the existence of solutions depends on the specific system characteristics. This paper demonstrates that such attacks exist for mobile robot dynamics, a significant finding in robotic security. However, fully generalizing perfectly undetectable FDIA to all nonlinear systems requires further research, as conditions for their existence may vary widely across different nonlinear plants.\nAs a countermeasure against perfectly undetectable FDIAs, a state monitoring approach using a signature function has been proposed. A sufficiently complex polynomial function is resilient against affine transformations. However, it should be noted that this approach has partial vulnerability to estimation attacks; given enough time and data, an attacker could potentially estimate the signature function through regression techniques, especially if they can observe a trajectory that covers a wide range of the workspace. Additionally, the example signature function discussed and analyzed in this paper is merely satisfactory. The signature function and its update frequency could be optimally determined once intended trajectories are given."

The experimental results using a Turtlebot 3 platform validate the practicality of implementing such attacks, emphasizing the urgent need for more robust security measures in Cyber Physical Systems (CPS).\nThis paper demonstrated that a typical mobile robot trajectory tracking control system is susceptible to perfectly undetectable false data injection attacks. Two specific types of perfectly undetectable FDIA are possible: scaling and reflection attacks, both based on affine transformations. These findings demonstrate the critical need for more robust detection mechanisms and resilient control strategies to protect such systems.\nFuture work will focus on developing effective countermeasures to mitigate the risks associated with these sophisticated cyberattacks and enhance system security in real-world applications including customization of SMSFs. Additionally, exploring response strategies that leverage machine learning could offer promising avenues for advancing the resilience of CPS against increasingly complex attack vectors. Furthermore, the introduction of time-variant perfectly undetectable attacks could lead to more sophisticated and powerful attacks compared to the simple scenarios mentioned in this paper."

While biological systems naturally exhibit robustness, there is no comprehensive understanding of how to achieve similar robustness in robotic systems. In this work, we draw inspirations from biological systems and propose a design principle that advocates active interconnections among system components to enhance robustness to environmental variations. We evaluate this design principle in a challenging long-horizon manipulation task: solving lockboxes. Our extensive simulated and real-world experiments demonstrate that we could enhance robustness against environmental changes by establishing active interconnections among system components without substantial changes in individual components. Our findings suggest that a systematic investigation of design principles in system building is necessary. It also advocates for interdisciplinary collaborations to explore and evaluate additional principles of biological robustness to advance the development of intelligent and adaptable robotic systems.",

This property is very desirable for robotic systems. However, outside of highly controlled environments, robotic systems rarely exhibit this property [2  ###reference_b2###]. There is currently no systematic understanding of how robustness can be built into robotic systems. In contrast, nearly all biological systems exhibit significant levels of robustness. We suggest that this discrepancy is due to a lack of understanding of the factors that contribute to robustness in robotic systems.\nThere are two main approaches to building robustness into robotic systems. The first one\u2014let us call it system engineering\u2014is motivated by best practices from engineering, and in particular software engineering. This school of system building is based on the assumption that robustness results from the encapsulation of complexity within the components, followed by composing the components into a system via simple interfaces [3  ###reference_b3###, 4  ###reference_b4###, 5  ###reference_b5###]. While this works well in the context of software, it does not work well for robotic systems that, unlike software, do not face well-defined inputs but instead must confront the unpredictability of the real world. System engineering advocates for a high degree of modularity, which is, as we will see, the opposite of how biological systems are \u201cengineered.\u201d\nThe second, more recent approach to system building can be termed end-to-end or data-driven learning. At the moment of writing this paper, no substantial real-world robotic systems have been produced exclusively based on this approach. Most end-to-end learning systems also contain parts that were engineered in the sense above. Nevertheless, the promise is that these systems will one day be robust, i.e., generalize to out-of-distribution environmental conditions. The architectural pattern presented in this paper may shed some light onto why and how end-to-end learning might be able to achieve such generalization (more in Section III-B  ###reference_###).\nBoth of these approaches have produced impressive robotic systems [6  ###reference_b6###, 7  ###reference_b7###, 8  ###reference_b8###, 9  ###reference_b9###], but neither has produced a systematic understanding of how to build systems for robustness.\nBiological systems, much like robotic systems, are composed of individual components. In contrast to engineered robotic systems, however, biological systems utilize complex, versatile, and redundant connections between components, rather than simple interfaces. This means that the behavior of the whole system results not only from the individual components, but also\u2014to a significant degree\u2014from the interconnection between them. We will delve deeper into these biological design patterns in Section II  ###reference_###. We then apply the principle to the design of a complex, real-world robotic system, as shown in Figure 1  ###reference_### and evaluate its performance in detail (Section VI  ###reference_###). We finally provide possible explanations for why this design approach enhances robustness and some interesting future directions for this design principle (Section VII  ###reference_###). Our extensive empirical evaluation of the resulting system confirms that this bio-inspired approach is indeed helpful for achieving robustness in robotic systems.\nOur results indicate that we must rethink how we build complex robotic systems for robustness. The proposed principle gleaned from biological systems is probably just one of many such patterns. Of course, we only demonstrate the benefit of this principle in a single system. But we believe that our community should perform a systematic investigation of this and other architectural patterns for robustness. We therefore believe that the robotics community would benefit from a focused examination of the factors that contribute to robustness in robotic (and biological) systems."

Giving this discrepancy, it does not seem far-fetched to attempt to learn something about robustness from biology. In this section, we examine several examples of striking biological robustness and attempt to extract a common pattern from them. This pattern then provides a specific hypothesis about how to achieve robustness in robotic systems. The rest of the paper is dedicated to our attempt to gather empirical evidence to assess the validity of the hypothesis.\nTo facilitate reading this section, we will start with the key message: Our hypothesis is that robustness in complex systems is produced by connecting the components of the system actively and in task-specific ways. By active we mean that the connection does not simply pass information from one component to the other. Instead, an active interconnection considers the current state of the two components it connects and adjusts the information that is passed accordingly. And by task-specific we mean that the way the information is actively adopted can depend on inductive biases. This can be either built into the system or derived in the interconnection from data. To summarize, our hypothesis is that robustness derives from active interconnections among system components.\nLet us now analyze some biological systems to see how this hypothesis is biologically inspired and supported."

This process reads off genes to translate the genetic information into a protein. But rather than having a dedicated gene in the genetic code for each protein, the DNA encodes reusable building blocks. Alternative splicing assembles building blocks into larger pieces of genetic information from which the proteins are produced.\nThe input to protein production is a string, a one-dimensional sequence, the genetic information. The output is a protein, a three-dimensional, molecular structure. The genetic information, in effect, encodes this three-dimensional structure. It is important to note that the identical one-dimensional genetic building block, when pieced together with other building blocks, produces different three-dimensional shapes in the complete protein. This variability results from the context a building block is placed in, in other words, from the other building blocks it gets connected to. (If Lego blocks had this property, the shape of the entire assembly would change with every added block.)\nWe now must consider the fact that already small variations in the genetic code can lead to the misfolding of proteins, when the protein does not assume the correct 3-D shape for fulfilling its biological function, often leading to the death of the biological entity. How is it then possible that these building blocks can be assembled in many different ways by alternative splicing and still reliably lead to the biologically relevant structure of the protein?\nThe process of evolution has selected for building blocks that can cooperate in many different ways to produce biologically active proteins. Being put into a specific context, the parts of the protein corresponding to the building block exchange \u201cinformation\u201d during the folding process that leads to biological function. Building blocks must be able to adjust their \u201cbehavior\u201d to their \u201cenvironment\u201d while still delivering a biologically functioning protein. The behavior of the protein (folding) is adjusted robustly by information exchange among the building blocks via physical forces that shape the folding process.\nThe robustness of protein folding from genetic material is based on versatile components (genetic building blocks) that exchange information (via physical force fields) to adjust their behavior (folding) to ensure a successful outcome (a biologically active protein).\nThe robustness of protein folding from genetic material is based on reusable components (genetic building blocks) that exchange information (via physical force fields) to adjust their behavior (folding) to ensure a successful outcome (a biologically active protein)."

These junctions facilitate versatile communication across cell membranes. It seems plausible that the variety of environmental conditions that cells are able to respond to (changes in temperature or pH level, invasion by pathogens, growth, differentiation, etc.) also necessitates equally diverse and tailored communication among the cells. This diversity in communication is indeed what we observe in cells [12  ###reference_b12###].\nIn this second example, we again encounter versatile information exchange among components (cells), actively adjusted to the context, leading to robustness, i.e., the ability to maintain performance under environmental variation."

This represents a broader trend wherein including a less immunogenic organ can enhance the long-term viability of a transplant involving a more immunogenic organ.

This strategy, which emphasizes a high degree of modularity\u2014a principle valued in software engineering\u2014offers several advantages. First, components with simple and well-defined interfaces are more easily replaceable, modifiable, and expandable [16  ###reference_b16###, 17  ###reference_b17###]. Additionally, by adopting the software engineering concept of encapsulation, component interconnections are often specified in the early stages of system design. This enables parallel development as developers can focus on individual components without requiring a comprehensive understanding of the entire system [18  ###reference_b18###, 19  ###reference_b19###]. Furthermore, strong modularization confines errors and failure modes to their corresponding components, preventing their propagation throughout the system [20  ###reference_b20###, 21  ###reference_b21###, 22  ###reference_b22###], thus simplifying the debugging process.\nThese benefits have led to the widespread adoption of the high-degree modularity in developing reusable robotic frameworks [23  ###reference_b23###] and libraries [24  ###reference_b24###, 25  ###reference_b25###].\nThis design principle has also demonstrated its effectiveness at building well-performing robotic systems in large-scale robotics challenges, such as the DARPA Robotics Challenge (DRC) [26  ###reference_b26###] and the Amazon Picking Challenge (APC) [17  ###reference_b17###, 27  ###reference_b27###].\nSystems resulting from high-degree modularity are typically characterized by isolated components and limited interconnections. Although the success of highly modular systems seems to contradict our hypothesized design principle, it\u2019s crucial to recognize that high-degree modularity primarily enhances robustness from a software engineering perspective. Software products often have well-defined requirements, and the main challenge is minimizing human errors to maximize economic returns. High-degree modularity addresses these challenges by optimizing the development process to improve robustness against human errors. However, while this type of robustness is desirable for software products, it fundamentally differs from the robustness required by robots to maintain system performance under significant, unpredictable environmental variations. In this work, we explore whether we can achieve this latter type of robustness by establishing diverse and active interconnections among system components."

Reactive planning addresses this limitation by advocating additional active interconnections between planning, perception, and control.\nFor example, action outcomes can inform planning to select appropriate controllers that react properly to perceived environmental changes [32  ###reference_b32###, 33  ###reference_b33###]. Furthermore, integrating perception and control into planning enables systems to use locally gained information to adjust global plans, resulting in more robust behaviors [34  ###reference_b34###, 35  ###reference_b35###, 36  ###reference_b36###, 37  ###reference_b37###].\nInteractive Perception [38  ###reference_b38###] is another paradigm supporting the idea of active interconnections leading to robust robotic behaviors. It exploits the regular relationship between actions and the corresponding sensory output to simplify manipulation through exploiting environmental constraints [39  ###reference_b39###, 40  ###reference_b40###, 41  ###reference_b41###, 42  ###reference_b42###], facilitate failure detection [43  ###reference_b43###, 44  ###reference_b44###], perform system identification [45  ###reference_b45###] and enhance the performance of exploration [46  ###reference_b46###, 47  ###reference_b47###].\nWhile the presented examples demonstrate the potential of active interconnectivity to generate robust robotic behaviors in response to environmental changes, no study has yet analyzed the correlation between active interconnection and system-level robustness.

Similar to related studies, our lockbox incorporates binary joint states, meaning that each joint can only be positioned at either end of its motion range. The lockbox is considered solved when a pre-specified joint, which we refer to as target joint, is moved to the end of its motion range.\nTwo key characteristics distinguish our lockbox problem from previous work. First, the robot must autonomously determine task-relevant properties of the lockbox, including joint configuration, joint count, grasp poses, and manipulation policies. This is a prerequisite for assessing the robustness of robotic behaviors in the real world.\nSecond, our lockbox contains three types of joint interdependencies with the last one significantly increasing the task complexity:\nOne-to-One: one joint locks another single joint\nMany-to-One: multiple joints lock one single joint\nBistable-Locking: one joint locks multiple joints at two different states\nThese three joint interdependencies can be represented as Directed Acyclic Graphs (DAGs) as visualized in Figure 2  ###reference_###.

We assume that handles are mounted parallel to the plane of the lockbox wall. We define a handle pose by selecting the longest side of the handle as the y-axis and aligning the z-axis with the plane\u2019s normal direction. We then apply Principal Component Analysis (PCA) on the detected bounding box to estimate the orientation of the handle and use depth measurements to determine its position relative to the robot base frame. After obtaining a handle pose in the robot base frame, we compute a relative transformation from the handle pose to a grasp pose for the grasping behavior.

If the maximum observed movement exceeds a predefined threshold, the manipulated joint is identified as movable. An innovative aspect of our system is its ability to autonomously manipulate various types of joints. This is achieved by establishing an active interconnection between perception and control, as explained later in Section V-B1  ###reference_.SSS1###."

It is important to mention that prior works on lockboxes assume that each joint is constrained by only one other joint or a joint can lock other joints in only one state [69  ###reference_b69###, 70  ###reference_b70###]. Therefore, their planning methods cannot be applied to our lockbox, which includes three types of joint interdependencies: one-to-one, many-to-one, and bistable-locking, as explained in Section IV  ###reference_###. We have to design a planning component to solve our lockboxes with increased complexity. To do so, we drew inspiration from human exploratory behaviors. We conducted an experiment where human participants solved lockboxes with various scales and interlocking dependencies in simulations. By analyzing how participants solved the lockboxes through interactions, we formulated a heuristic-based solver and incorporated it into our planning component.\nThis heuristic-based solver, described in Algorithm 1  ###reference_###, operates as follows: It starts by assessing the locking state (movable or locked) of every joint  from the set of detected joints  (lines 1 to 5). Joints that can be moved are added to the set of free joints , and the locked ones to the set of locked joints  (line 6). Now the algorithm iterates over the next two steps until the target joint  becomes movable, i.e. the lockbox is solved. The first step is to realize a state-combination  from the set of all possible combinations , that can be realized with the free joints (lines 10 to 17). Second, every joint from the set of locked joints is tried (lines 18 to 25). During these two steps, if a locked joint moves (second step) or a joint assumed movable becomes locked (first step), the current attempt is abandoned. This triggers a restart of the iterative process with the updated combinations set , taking the changes to  into consideration (line 8).\nThe sequence of free joint combinations and the order of attempting locked joints are crucial for efficiently solving a lockbox. In the next subsection, we will explain how to achieve efficient solving behaviors by leveraging active interconnections between perception, control, and planning to create an attention mechanism. This attention mechanism will guide the heuristic-based solver in the elements marked with * (line 8 and 18)."

This manipulation requires a model of the kinematic structure of those mechanical joints. Rather than first acquiring such a model to then enable control to operate the joint, we create an active interconnection between perception and control for the model building. In this active interconnection, information about the mechanical joint (obtained initially from random motion) is used to enable effective manipulation of the joint. This, in turn, creates more motion in the mechanism, revealing more information about the joint. The active interconnection produces a cycle of mutual information exchange that produces robust motion and produces an accurate model of the mechanical joint, at the same time. By actively interconnecting perception and control, we have reduced the system\u2019s dependency on models and made it robust to model inaccuracies. We have improved the robustness of the system by adding an active interconnection.\nThe active interconnection is implemented as follows: It begins by using the perceived end-effector displacement, , obtained initially from the robot\u2019s wiggling behavior (see Section V-A2  ###reference_.SSS2###), to compute the admissible motion direction  of the manipulated joint. The control component then directs the end-effector along this computed direction to reveal more end-effector motion. This, in turn, facilitates estimating the joint\u2019s admissible motion direction, thus closing the feedback loop. This active interconnection simultaneously estimates and guides the robot toward the joint\u2019s admissible motion direction, enabling the robot to manipulate various mechanical joints with 1 DoF.\nNote that applying this active interconnection with a soft end-effector is not straightforward. The deformations of the soft end-effector during forceful interactions can lead to noisy end-effector displacement observations, resulting in poorly estimated admissible motion directions. This inaccuracy may cause the robot to lose contact with the mechanical joint\u2019s handle, leading to manipulation failures. To address this issue, we introduce an additional active interconnection between perception and control to regulate the wrench during manipulation, thereby minimizing the deformation of the soft end-effector.\nThis additional active interconnection works as follows: Given a desired pose D in the base frame B namely , we first interpolate the goal in the exponential coordinate  with a twist limit  as:\nwhere  is the interpolated pose in the timestamp  and  is the control period. We then constraint  based on the difference between the observed wrench  measured by the wrist-mounted Force/Torque sensor and a wrench limit :\nwhere the  function is used as a smoothing factor. When  exceeds wrench limits,  flips the interpolation direction to reduce the observed wrench . After obtaining the wrench-limited relative pose , we can compute the desired end-effector pose  and move the robot using an Cartesian impedance controller [79  ###reference_b79###].\nThe key idea of this active interconnection is to integrate the perceived wrench measurements into the trajectory generator that rapidly adjusts the equilibrium pose , allowing the robot to manipulate joints within a predefined wrench threshold, thus limiting the undesired end-effector\u2019s deformations. An example of this active interconnection in manipulating joint D is visualized in Fig 5  ###reference_###. This active interconnection is crucial for accurately estimating the admissible motion direction during manipulation with a soft end-effector, preventing manipulation failures such as loss of grasp, thus contributing to robust forceful manipulation behaviors.\n###figure_7###"

In addition to manipulating the lockbox\u2019s individual joints, the robot must also reason about their interlocking dependencies to solve the lockbox efficiently. In addition to assessing the binary state of each mechanical joint (locked or unlocked), the features of the mechanical joints, e.g., positions or kinematic joint types, could also be useful to improve the solving efficiency. For example, in a physical lockbox, nearby mechanical joints are more likely to influence each other than distant ones. Therefore, establishing an active interconnection that exploits the perceptual information about the environment to support the planning component can lead to more robust systems.\nFor our system, we consider two environmental features that could complement the planning component in solving lockboxes: the Cartesian positions of each joint handle, denoted as , and its kinematic joint type . We determine the handle positions during the handle detection process (Section V-A1  ###reference_.SSS1###). For the kinematic joint type detection , we apply PCA on the performed end-effector trajectory after a successful joint manipulation:\nwhere  denote the first three eigenvalues of the end-effector trajectory sorted in descending order,  denotes the sum of all eigenvalues, and  is the threshold for distinguishing prismatic from revolute joints.

Instead of relying on preprogrammed prioritization patterns\u2014such as a mechanical joint is more likely to unlock closer joints than joints farther away\u2014we designed this active interconnection with the ability to adapt its prioritization dynamically based on previous interaction experiences. This online adaptation capability eliminates the dependency on predefined patterns of interlocking dependency, allowing the system to adjust to a wide range of configurations beyond pre-specified changes.\nThe active interconnection operates as follows: it computes the absolute differences in environmental features between the last manipulated joint and the remaining joints in the lockbox, namely the changes in position along each axis  and differences in joint type . The active interconnection then processes these feature differences to calculate a manipulation-priority score for each joint. Joints with higher scores are more likely to be successfully manipulated and are therefore prioritized in the planning sequence. Importantly, this active interconnection is based on a ridge regression model [80  ###reference_b80###], which is lightweight and allows the model\u2019s weights to be updated online without pre-training. Specifically, we update the weights using the results of the last five trials, labeling a trial as 1 if the robot successfully operates a joint and -1 otherwise.\nThe contribution to the robustness of this active interconnection is grounded on the ability to identify and exploit the interlocking patterns in an online manner. As demonstrated in our later experiment (Figure 9(b)  ###reference_sf2###), this active interconnection can effectively adapt to various lockbox configurations by online learning these patterns from the interaction experience."

Additionally, it minimizes the joint-wiggling process (see Section V-A2  ###reference_.SSS2###), which can be time consuming, because the robot only needs to evaluate motion along the known admissible motion direction, saving time and resources.\nIn order to rescue manipulation models, an active interconnection between control and planning components is required.

This interconnection leverages the robot\u2019s ability to move its camera, revealing task-relevant visual information. The newly obtained visual data then guides further camera movements, creating a recursive cycle of information gathering that would be impossible to achieve without interconnecting components.\nSpecifically, this active interconnection exploits three key relationships between perception and control. First, after detecting handles, we center them in the image frame, which effectively minimizes perspective distortion. Second, as presented by [81  ###reference_b81###], moving the camera closer to a detected handle increases depth resolution, thereby reducing noise in the visual input. Third, inspired by [82  ###reference_b82###], we actively rotate the camera to identify a bounding box with minimal background interference, which is then used for more precise handle pose estimation.\nBy leveraging the active interconnection between control in perception, we obtain more accurate pose estimations, as visualized in Figure 6  ###reference_###.\nFurthermore, this active interconnection allows the robot to effectively detect and track all handles within the lockbox, even with the limited field of view inherent to eye-in-hand setups.

It is necessary to perform such an active search behavior as we only use a wrist-mounted camera to receive vision information. Subsequently, the robot fine-tunes each handle pose using the Active Grasp Pose Estimation method and generates a grasp pose accordingly. These estimations, including the number of joints and handle poses, are used to initialize the planning and control components. After that, the robot iteratively manipulates the joints of the lockbox. When the robot encounters an unexplored joint, it first wiggles the joint. If the joint is movable, it autonomously manipulates the joint by following its articulation (Acquisition of Manipulation Models). The resulting end-effector trajectory is stored in the planning component, allowing the robot to reuse this trajectory if the joint needs to be manipulated again (Reuse of Manipulation Models). Note that this end-effector trajectory is also used to estimate the joint type, which, together with the positions of joint handles as environmental features, will be used by Guided Exploration to inform the planning component."

We start by introducing a minimally interconnected baseline system capable of solving the lockbox task. We then incrementally introduce additional active interconnections to create a series of systems. The baseline system (referred to as Base) incorporates essential active interconnections for solving lockboxes, including the Acquisition of Manipulation Models with the wrench-gated trajectory generator (Section V-B1  ###reference_.SSS1###) and the active exploration module for handle localization (Section V-A1  ###reference_.SSS1###).\nTo distinguish between the various active interconnections, we employ a color-coded scheme for the associated components: P for perception, C for control, and P for planning. We now describe the robotic systems evaluated in our experiments, characterized by varying degrees of active interconnections:\n###table_1### Base: the base system that contains only necessary component interconnections for solving lockboxes\nBase + PC: the base system with one additional interaction between perception and control (PC) that allows the robot to perform Active Grasp Pose Estimation\nBase + PCP + PC: the base system with two active interconnections that allow the planning component to leverage the environmental features afforded by perception and control to perform  Guided Exploration (PCP) and the interconnection required for Active Grasp Pose Estimation (PC)\nBase + PCP + CP: the base system with two additional interconnections for Guided Exploration (PCP) and Reuse of Manipulation Models (CP)\nBase + PCP + PC + CP: system with the highest number of active interconnections among components as described in Section V-C  ###reference_###\nIt is worth noting that our Base system already covers a greater spectrum of lockbox complexities than previous works as summarized in Table I  ###reference_###. Concretely,  [69  ###reference_b69###, 70  ###reference_b70###] mainly focused on the high-level reasoning of interlocking dependencies. Thus, they significantly implied the lockbox manipulation task, such as assuming manipulation policies for mechanical joints are known.  [71  ###reference_b71###] presents a lockbox-solving framework that autonomously acquires manipulation policies for individual mechanical joints and reasons for the interlocking dependency. However, the proposed framework is only evaluated in simulation. Moreover, manipulation policies for mechanical joints are often trained using reinforcement learning algorithms, which require extensive interactions and environment resets, making it difficult to validate in real-world settings [71  ###reference_b71###, 83  ###reference_b83###, 73  ###reference_b73###]. By contrast, our Base system with a minimal degree of active interconnections has the ability to solve various lockboxes in the real world without the need for prior training.\nIn the following sections, we will evaluate the performances of the aforementioned systems in both simulated and real-world environments. To assess system robustness, we introduced variations in lockbox scale, interlocking dependencies, robot pose, and joint type. Our experimental findings demonstrate a clear correlation between the amount of active interconnections and the system\u2019s robustness to these environmental changes."

The simulated lockboxes share the same parameters (i.e. joint types and positions) with the physical lockbox but have two additional joints (F and G), as illustrated in Figure 3  ###reference_###. Conducting this experiment in simulations allows us to test the robustness of the systems in solving large variations of lockboxes. For example, we can significantly increase the scale of the lockbox without considering the reachability-limitation that real robots have to deal with. We can also introduce more abstract lockbox-configurations that cannot be realized mechanically but can occur in electric puzzles.\nWe compare the lockbox-solving performance of three different systems. We assume these systems can physically manipulate each mechanical joint. The first system is Base which relies on our heuristic-based planning component to solve different lockboxes. The second system is Base + PCP + PC + CP which assists the planning component with environmental features (i.e., joint types and positions) afforded by the active interconnection between perception and control.\nThe third system is a Reinforcement Learning (RL) agent. This system employs a deep Q-Network (DQN) agent [84  ###reference_b84###] for planning. The DQN is trained using RL on randomized lockbox configurations for 10,000 episodes. The agent takes the joint states represented as a vector of binary values and the one-hot encoded index of the last attempted joint as input. The agent then predicts a quality value for each joint. The DQN architecture consists of a fully connected network with an input layer of size , with  denoting the number of joints in the lockbox, a hidden layer with 64 units, and an output layer of size . At each step, the agent receives a reward of , which is computed as the difference in the minimal number of remaining steps to solve the lockbox before and after manipulating a joint. Additionally, the agent receives a reward of 5 upon successfully solving the lockbox. Due to the fixed input size of the DQN, we have to train a distinct DQN agent for each lockbox scale (number of joints). Similar to the Base system, this baseline treats planning as a separate component, with no active interconnections to other components.\n###figure_11### We assess the performances across four different scales of lockboxes, spanning from 4 to 7 joints. The simulated lockboxes share the same joint positions, joint types, and interlocking dependencies with the physical lockbox. To maintain a generalizable evaluation of the DQN agent, which operates deterministically and would easily overfit to particular lockbox configurations, we randomize the joint labels (except for the target joint). This randomization is applied in each trial and for all systems. Each system undergoes evaluation through 1000 trials for each lockbox configuration. We define a trial as successful if the system succeeds at moving the target joint within 1000 manipulation steps. Figure 8  ###reference_### shows the success rates and required number of manipulation steps for these systems.\nFigure 8  ###reference_###.a visualizes the impact of the three different systems on performance. We can clearly see that our Base and Base + PCP + PC + CP systems achieve a 100% success rate across all lockbox scales. In contrast, the DQN system requires extensive training for each lockbox scale and exhibits a significant decline in success rate as the number of joints increases. Notably, the DQN system only solves 3.2% of the lockboxes with 7-joints.\nThis disparity in performance is primarily due to the DQN\u2019s limited generalization capability. The DQN can only solve a lockbox if it has previously encountered its specific interlocking dependencies during training. As the number of joints increases, the combinatorial explosion of potential dependencies renders it increasingly improbable for the DQN to have encountered all relevant configurations during training, leading to a decline in performance.\nThese findings support the observations in [70  ###reference_b70###] and [53  ###reference_b53###] that RL struggles with extracting transferable policies, especially for long-horizon sequential manipulation tasks. Additionally, the substantial performance gap between the DQN and the other systems underscores the complexity of our lockbox problem, particularly due to the presence of bistable-locking joints as discussed in Section IV  ###reference_###.\nIn addition to success rates, Figure 8  ###reference_###.b also highlights that the Base + PCP + PC + CP system requires significantly fewer manipulation steps compared to the Base system. This gap widens as the lockbox complexity increases. The substantial difference in manipulation steps indicates that the planning component benefits greatly from the guidance provided by the active interconnection between the perception, control, and planning components. This active interconnection facilitates more efficient exploration by reducing unnecessary attempts that could lead to failures and consequently contributing to more robust behaviors. This result confirms the contribution of active interconnections to the robustness against various lockbox scales.\nWe now examine whether active interconnections can also contribute to robustness against variations in the interlocking dependency. To do so, we designed a fictive configuration (Interlocking Dependency 2), as shown in Figure 9(a)  ###reference_sf1###.\nIn this new configuration, joints are more likely to be locked by distant joints, rather than nearby joints, as in the previous configuration (Interlocking Dependency 1). We test whether the Base + PCP + PC + CP system with the attention mechanism is still able to improve the planning efficiency in this new configuration. We ran 1,000 trials for both Base and Base + PCP + PC + CP systems and compared the required number of manipulation steps to solve the lockbox and the learned weights of the attention mechanism.\n###figure_12### ###figure_13### The Base + PCP + PC + CP system solves the lockbox with Interlocking Dependency 2 within an average of 8.9 manipulation steps, whereas the Base system averages at 12.64 steps. It shows that the attention mechanism afforded by the active interconnection between perception, control, and planning improves the planning efficiency by 29.6%. This improvement can be explained by the learned weights, as visualized in Figure 9(b)  ###reference_sf2###. In Interlocking Dependency 1 (matching the physical lockbox), the attention mechanism assigns negative weights to the features , prioritizing joints closer to the last attempted joint. In Interlocking Dependency 2, the weights become positive, indicating that joints farther from the last attempted joint are prioritized. The difference in learned weights shows the attention mechanism\u2019s ability to extract appropriate inductive biases through online weight adaptation, thus enhancing planning performance across various lockbox configurations.\nOverall, our experiments demonstrate that the Base + PCP + PC + CP system characterized by a high degree of active interconnections exhibits high adaptability and efficiency in solving lockboxes across diverse environmental conditions, including variations in scale and configuration. Notably, this enhanced robustness is attained without significant modifications to individual system components but through the strategic establishment of active interconnections between them."

This is because the robot has to perform extensive forceful interactions with the mechanical joints to acquire their locking-state (locked or unlocked) and their manipulation policies.

It is important to note that the DQN agent (in simulation) managed to solve only 30% of the trials on this scale of the lockbox. As we explained earlier, this robustness is attributed to the different active interconnections between the system\u2019s components, which enable efficient planning and robust real-world manipulation behaviors. Note that we could not significantly vary the pose of the robot in the experiment involving the 5-joint lockboxes as we could do with the 4-joint lockboxes. This is due to the limited manipulation range allowed by our current robot platform. To address this limitation, we are working on integrating the robot platform into a mobile base.\nFirst, we validate the system\u2019s robustness to pose changes (i.e., generalizes to new lockbox poses). We conducted 10 trials with different robot base poses within the robot\u2019s joint limits, as shown in Figure 12  ###reference_### and Extension 2  ###reference_Ekw0FkuU9fagq2-p_D2C2Ps/view?usp=drive_link###. Our Base + PCP + PC + CP system successfully maintained its performance, solving the lockbox in all 10 trials. This robustness stems from the active interconnection between perception and control, allowing the robot to actively search for and accurately locate handles of mechanical joints in the lockbox.\n###figure_16### Next, we demonstrate the ability of our Base + PCP + PC + CP system to adapt to changes in the morphology of the end-effector caused by finger impairment. We did this by disabling certain fingers of the end-effector and running the system to solve the lockbox. Our Base + PCP + PC + CP system accomplished the task with 6 morphological variations, as illustrated in Figure 13  ###reference_### and Extension 3  ###reference_di5IMOsvAekdeRUrAKkBfXb/view?usp=drive_link###. This robustness stems from using the wrench-gated trajectory generator, enabled by the active interconnection between perception and control (see Section V-B1  ###reference_.SSS1###). This active interconnection allows the system to compliantly manipulate the joints within a desired wrench limit, as visualized in Figure 5  ###reference_###. By setting a wrench limit that suffices with three fingers, the system can exploit the redundancy of the end-effector and remain robust with up to two fingers being impaired.\n###figure_17### ###figure_18### ###figure_19### ###figure_20### ###figure_21### ###figure_22### Our findings underscore the system\u2019s capacity to adapt to diverse environmental conditions without fundamental structural modifications. Crucially, these results emphasize that fostering active interconnections among system components is crucial for achieving robust robotic behavior. This approach diverges from the traditional focus on individual component sophistication. By exploring this new design paradigm, we identify a promising avenue for enhancing behavioral diversity, a critical factor in adaptability in complex environments."

However, our experiments have also highlighted some limitations, indicating a need for more active interconnections among the system\u2019s components.\nOur physical lockbox uses standard door handles, simplifying the affordance prediction problem. However, real-world scenarios involve diverse elements. A desired extension is to incorporate an affordance prediction model [85  ###reference_b85###]. As suggested in [86  ###reference_b86###, 87  ###reference_b87###, 81  ###reference_b81###], the robot must refine the affordance prediction results through active exploration, which highlights the need for additional active interconnections between perception and control.\nOur current system assumes all joints being single-DoF, simplifying the manipulation problem. For multi-DoF joints, a new system component is necessary to learn suitable manipulation policies. [88  ###reference_b88###] and [89  ###reference_b89###] propose such components that learn from human demonstrations. Importantly, they further refine initial policies by incorporating exploration actions to discover states not covered in the demonstrations, showing advantageous interconnections between learning and other system components, such as perception and control.\nThe system currently assumes binary states for all joints and a deterministic environment. However, the interaction with a lockbox in the real world is probabilistic, failures could occur if joint states deviate from the binary state assumptions due to errors in perception and actuation. This highlights the need for a failure recovery mechanism [90  ###reference_b90###, 36  ###reference_b36###], necessitating more intricate active interconnections between the perception, control, and planning components to effectively detect erroneous positions of mechanical joints and autonomously recover from such failure situations.\nIn summary, these limitations suggest even more active interconnections between system components to further enhance the robustness against a boarder range of environmental variability in the lockbox manipulation task."

The key to robust control is the choice of an appropriate control function, describing the mapping from input to output of the controller. Control functions lead to robust system behavior when they represent a regularity of the system they control.\nA regularity is a reproducible and predictable relationship between the robot\u2019s embodiment, features of the environment, and the behavioral consequences of their interactions. A regularity limits the degrees of freedom in the space in which the control function is described. This function can then be viewed as a lower-dimensional manifold in that space. Regularities capture a property of the world that is relevant to the robot. They facilitate the rejection of disturbances, aid with the interpretation of percepts, and simplify the selection of actions. In short, regularities are the foundation of robustness in robotic systems.\nThe Jacobian matrix of a robotic manipulator is an example of regularity. It captures the relationship between changes in joint angles and changes in end-effector pose.\nIf a task requires the control of the end-effector via the joint variables, exploiting this regularity improves robustness. There are many examples of robots exploiting regularities, such as performing guarded moves, achieving force closure, or servoing to a visual target.\nOther disciplines also rely on regularities. In machine learning, for example, regularities are sometimes called inductive biases or priors. Representation learning can be understood as the automated attempt to extract regularities from data."

+            "text": "When designing robotic systems, roboticists endow their systems with the ability to exploit regularities. These regularities occur in all components of the system: planning, control, perception, reasoning, learning, and even the choice of hardware determines which regularities can be exploited. Regularities are so ubiquitous in robotics that we use them without thinking about it.\nOur main argument to explain the empirical results reported in this paper is the following. Active interconnections enable a more versatile composition of regularities in behavior generation when compared to passive interconnections. Since robustness stems from the ability to exhibit appropriate behavior in the presence of environmental variations, the ability to vary the behavior more richly enables robustness.\nThe conventional way of designing robotic systems with a high degree of modularity and simple interfaces between them leads to a simple form of composition. The interfaces are simple and passive and therefore limit how regularities can be composed. In contrast, active interconnections enable more complex compositions. They can adapt the information they pass back and forth based on the state of all of the components they connect, enabling new kinds of active compositions that are responsive to the environment as reflected in the state of the system.\nWe use an analogy to illustrate our argument. Let us regard regularities as basis vectors of the space of behaviors. Behavior results, as before, from the composition of these basis vectors. In this analogy, highly modular systems might represent linear combinations of the basis vectors. In contrast, active interconnections enable compositions based on any function. They can cover the space of behaviors in much more interesting ways.\nGiven the same regularities in a highly modular system and in a system with active interconnections, we believe the following to be true: A robotic system with active interconnections has more ways of responding to variability in the world because it can compose regularities in a more versatile manner. Such robotic system can also be more skilled at selecting from this richer set of behaviors because this selection can be based on information about several system components. The result is that active interconnections contributes to robustness in robotic systems."

This offers an intriguing perspective on designing robotic systems: designing active interconnections rather than overly sophisticated individual components. To apply this design principle, we must carefully consider the way we collaborate in system building.\nFrom our experiences, we argue that collaborative development is crucial in designing systems with active interconnections. In particular, developers should frequently communicate about each component\u2019s limitations and challenges. This frequent knowledge exchange fosters the developer in attaining a good understanding of the bottlenecks and issues faced by the whole system. This shared understanding enables the developers to implement complex and robust robotic behaviors by establishing active interconnections between components.\nNotably, the proposed collaborative development with frequent knowledge exchange contradicts the standard software engineering practice, which suggests designing well-defined interfaces in the beginning design stage so that developers can focus on individual components, purposely minimizing communication with developers of other modules. The discrepancy arises from different design purposes: standard software engineering practice optimizes the development process against errors introduced by developers, while our engineering practice aims to enhance robustness against environmental changes by adding regularities via advantageous interconnections among system components, which requires a shared understanding about the whole system among developers. Notably, this collaborative method aligns with previous research [91  ###reference_b91###], highlighting the importance of early and continuous integration of ideas."

Applying the proposed design principle to other tasks requires significant effort to understand the task, identify relevant patterns, and design suitable connections between components. As task complexity increases, this manual design process becomes increasingly intricate. Therefore, it is desired to use data-driven approaches to facilitate the design of robotic systems with data from either human demonstrations [92  ###reference_b92###] or autonomous explorations [93  ###reference_b93###, 94  ###reference_b94###].\nInterestingly, in an end-to-end learning framework, system components are jointly optimized through data, achieving comprehensive interconnectivity with minimal information loss. Such learning systems seem capable of automatically identifying and exploiting task-relevant regularities, thereby enhancing system robustness. However, these end-to-end approaches, while embodying the principle of active interconnections, often struggle to efficiently identify suitable regularities from limited data. Moreover, the regularities learned may lack the desired level of abstraction, leading to overfitting and reduced robustness to out-of-distribution scenarios.\nA promising intermediate step is to introduce the structure of active interconnections while relying on data to extract the necessary parameters for instantiation. This approach allows us to encode prior knowledge about the task structure, thereby facilitating the learning process. This is exemplified by our Guided Exploration behavior, which employs an attention mechanism to learn regularities in interlocking dependencies from online interaction experiences. Other examples can be found in [95  ###reference_b95###, 96  ###reference_b96###] where the structure of active interconnections is based on recursive estimators, allowing the prediction and measurement models to be learned or refined from data."

We tested their performance in manipulating lockboxes under significant environmental changes, including variations of the lockbox in scale, interlocking dependencies, joint types, relative lockbox/robot poses, and morphologies of the robot\u2019s end-effector. Our experimental results support that systems with higher amounts of active interconnections among components exhibit greater robustness under environmental variations. While this design principle has been only demonstrated in one task, we believe that our scientific arguments, examples from biological systems, empirical evidence, and system limitations showcase the potential of applying this principle to achieve robustness in a broader range of manipulation tasks. Undoubtedly, the proposed principle is not the sole pattern contributing to the robustness of biological systems. We hope this work stimulates interdisciplinary collaborations between biologists and roboticists to explore additional principles of biological robustness."

The resulting end-effector trajectory is stored in the planning component, allowing the robot to reuse this trajectory if the joint needs to be manipulated again.

+    "abstract": "Open-world 3D generation has recently attracted considerable attention. While many single-image-to-3D methods have yielded visually appealing outcomes, they often lack sufficient controllability and tend to produce hallucinated regions that may not align with users\u2019 expectations. In this paper, we explore an important scenario in which the input consists of one or a few unposed 2D images of a single object, with little or no overlap. We propose a novel method, SpaRP, to reconstruct a 3D textured mesh and estimate the relative camera poses for these sparse-view images. SpaRP distills knowledge from 2D diffusion models and finetunes them to implicitly deduce the 3D spatial relationships between the sparse views. The diffusion model is trained to jointly predict surrogate representations for camera poses and multi-view images of the object under known poses, integrating all information from the input sparse views. These predictions are then leveraged to accomplish 3D reconstruction and pose estimation, and the reconstructed 3D model can be used to further refine the camera poses of input views. Through extensive experiments on three datasets, we demonstrate that our method not only significantly outperforms baseline methods in terms of 3D reconstruction quality and pose prediction accuracy but also exhibits strong efficiency. It requires only about 20 seconds to produce a textured mesh and camera poses for the input views. Project page: https://chaoxu.xyz/sparp.",

Although traditional photogrammetry [1  ###reference_b1###, 57  ###reference_b57###, 64  ###reference_b64###] and recent neural field methods [43  ###reference_b43###, 77  ###reference_b77###, 91  ###reference_b91###] have made significant strides in reconstructing high-fidelity geometry and appearance, they typically require dense view inputs. However, in many practical scenarios, such as in e-commerce and consumer capture situations, acquiring a comprehensive set of high-resolution images along with precise camera data is not always feasible.\nOn the other end of the spectrum, the tasks of converting a single image to 3D and text to 3D have recently seen substantial progress [46  ###reference_b46###, 30  ###reference_b30###, 28  ###reference_b28###, 32  ###reference_b32###, 62  ###reference_b62###, 80  ###reference_b80###], thanks to the rich priors embedded in 2D diffusion models [50  ###reference_b50###, 54  ###reference_b54###, 53  ###reference_b53###] and pre-training on extensive 3D datasets [9  ###reference_b9###]. These methods may achieve high-quality geometry and texture that matches the input view, but they also introduce ambiguities in the regions not visible in the input image (such as the back view). Although these methods attempt to hallucinate reasonable interpretations of these invisible areas, the generated regions may not always align with users\u2019 expectations, and users often lack sufficient control over these ambiguous regions.\nIn this paper, we explore a critical scenario where the input consists of one or a few unposed 2D images of a single object. The images are captured from arbitrarily distributed camera poses, often with little to no overlap. We tackle both the 3D reconstruction and pose estimation of input images under this sparse view setting. Note that, in dense view setting, traditional Structure-from-Motion (SfM) solvers (e.g., COLMAP [58  ###reference_b58###]) are typically employed for pose estimation. However, with sparse view inputs, these solvers often become unreliable and tend to fail due to insufficient overlapping visual cues. This issue is the main reason why existing sparse view reconstruction methods [22  ###reference_b22###, 39  ###reference_b39###, 97  ###reference_b97###] generally require known camera poses as input. While some recent methods have attempted pose-free reconstruction and pose estimation for sparse views [29  ###reference_b29###, 63  ###reference_b63###, 95  ###reference_b95###, 17  ###reference_b17###, 18  ###reference_b18###], they are usually trained on a predefined small set of object categories and exhibit poor generalization to unseen object categories.\nIn response, we propose an innovative class-agnostic approach called SpaRP, capable of processing arbitrary object categories with unposed sparse views. Our inspiration comes from recent breakthroughs in open-domain single-image-to-3D methods. They leverage 2D diffusion models (e.g., Stable Diffusion [53  ###reference_b53###]) to generate novel viewpoints of an object [35  ###reference_b35###], and even consistent multi-view images from a single input image [62  ###reference_b62###, 60  ###reference_b60###, 28  ###reference_b28###, 36  ###reference_b36###, 38  ###reference_b38###], by finetuning the diffusion models with corresponding multi-view image pairs. These discoveries imply that 2D diffusion models harbor rich priors concerning 3D objects. Instead of merely producing multi-view images, we contemplate leveraging 2D diffusion models to examine a set of unposed input images from sparse viewpoints, infer their spatial interrelationships, and recover relative camera poses and underlying 3D shapes.\nSpecifically, we finetune a 2D diffusion model [53  ###reference_b53###] to process sparse input views by compositing them into a single image for conditioning. The diffusion model is concurrently tuned to deduce the relative poses of the input images and the underlying 3D objects. For the relative pose estimation branch, instead of outputting camera poses as scalars, we task 2D diffusion models to produce a surrogate representation: the NOCS maps [74  ###reference_b74###] that embed pixel-wise correspondences across different views and are more suitable for 2D diffusion models. From these maps, we extract the relative camera poses for the sparse views using the traditional PnP algorithm [2  ###reference_b2###], assuming known camera intrinsics. For the reconstruction branch, the diffusion model is tasked to produce multi-view images of the object from fixed known camera poses, covering the entire 3D object. This task requires the models to incorporate all information from input sparse views and hallucinate invisible regions. We then feed the generated images with fixed known poses into a pre-trained 3D reconstruction module [32  ###reference_b32###] to create a textured 3D mesh. We can further refine the estimated camera poses by aligning the input views with the generated mesh through differentiable rendering [26  ###reference_b26###].\nWe train SpaRP on the Objaverse [9  ###reference_b9###] dataset with 1\u20136 unposed input views. Unlike some previous methods that rely on costly per-shape optimization [83  ###reference_b83###], our method delivers 3D textured meshes along with camera poses in a much more efficient manner, requiring only 16 seconds. As shown in Fig. 1  ###reference_###, our approach can faithfully generate 3D assets that closely follow the reference unposed images, effectively overcoming the ambiguity issue of single-image-to-3D. Extensive evaluation on three datasets demonstrates the superior performance of our method over baselines in reconstructing 3D meshes with vivid appearance and high-fidelity geometry, alongside precise pose estimation of the input images."

When a small baseline between images is assumed, several methods [4  ###reference_b4###, 39  ###reference_b39###, 51  ###reference_b51###, 70  ###reference_b70###, 93  ###reference_b93###, 19  ###reference_b19###, 24  ###reference_b24###, 37  ###reference_b37###, 52  ###reference_b52###, 76  ###reference_b76###, 79  ###reference_b79###, 89  ###reference_b89###] have pretrained generalizable models to infer surface positions by establishing pixel correspondences and learning generalizable priors across scenes. However, these methods often fail to produce satisfactory results when the sparse-view images have a large baseline. Some studies have attempted to alleviate the dependence on dense views by incorporating priors or adding regularization [61  ###reference_b61###, 16  ###reference_b16###, 22  ###reference_b22###, 45  ###reference_b45###] into the NeRF optimization process. Others have employed 2D diffusion priors to generate novel-view images as additional input for the NeRF model [97  ###reference_b97###, 3  ###reference_b3###, 68  ###reference_b68###, 21  ###reference_b21###]. For example, ReconFusion [84  ###reference_b84###] trains a NeRF from sparse-view images and uses a denoising UNet to infer some novel view images as support for the NeRF model. EscherNet [23  ###reference_b23###] utilizes Stable Diffusion for novel view synthesis and designs a camera positional encoding module to yield more consistent images. Furthermore, some recent works [38  ###reference_b38###, 36  ###reference_b36###, 62  ###reference_b62###] have integrated specialized loss functions and additional modalities as inputs into NeRF-based per-scene optimization.\nIn contrast to these methods, our approach does not require camera poses for the input sparse views. It is not limited to small baselines and is capable of generating 360-degree meshes. Furthermore, without the need for per-shape optimization, our method can quickly produce both textured meshes and camera poses in about 20 seconds."

When provided with dense images, some approaches  [31  ###reference_b31###, 81  ###reference_b81###, 86  ###reference_b86###] jointly optimize the NeRF representation along with camera parameters. However, due to the highly non-convex nature of this optimization problem, such methods are susceptible to initial pose guesses and can become trapped in local minima. This issue worsens when input images are sparse, with increasing ambiguity and reduced constraint availability. In response, numerous proposals have attempted to enhance optimization robustness. For example, SpaRF [71  ###reference_b71###] uses dense image matches as explicit optimization constraints, while FvOR [90  ###reference_b90###] starts with coarse predictions of camera poses and alternated updates between shape and pose.\nIn contrast to the optimization-based methods, there is a body of research proposing generalizable solutions for this problem. VideoAE [25  ###reference_b25###] infers scene geometry from the first frame in a video series and estimates camera poses relative to that frame, which allows for warping scene geometry to decode new viewpoints. SparsePose [63  ###reference_b63###] first regresses and then iteratively refines camera poses. FORGE [17  ###reference_b17###] designs neural networks to infer initial camera poses, fuse multi-view features, and decode spatial densities and colors. GRNN [72  ###reference_b72###] offers a GRU-based reconstruction method estimating the relative pose for each input view against a global feature volume. The RelPose series [95  ###reference_b95###, 29  ###reference_b29###] use probabilistic modeling for relative rotation estimation between images. Other works [55  ###reference_b55###, 18  ###reference_b18###] eschew explicit camera pose estimations, instead employing transformers to encode input views into latent scene representations for novel view synthesis.\nMore recently, leveraging large vision models and diffusion models, which have shown significant promise, new efforts have emerged for camera pose estimation. PoseDiffusion [75  ###reference_b75###] implements a diffusion model guided by 2D keypoint matches to estimate poses. PF-LRM [78  ###reference_b78###] adapts the LRM model [14  ###reference_b14###] to predict a point cloud for each input image, then utilizes differentiable PnP for pose estimation. iFusion [83  ###reference_b83###] employs an optimization pipeline to assess relative elevations and azimuths. It utilizes Zero123 [35  ###reference_b35###] predictions as a basis and optimizes the relative pose between two images by minimizing the reconstruction loss between the predicted and target images.\nIn contrast to these existing approaches, our proposal capitalizes on the extensive priors inherent in pre-trained 2D diffusion models, thereby providing exceptional generalizability to handle a diverse range of open-world categories. Our method predicts camera poses and 3D mesh geometry in a single feedforward pass, negating the need for per-shape optimization."

+            "text": "Recently, numerous studies have shown that 2D diffusion models not only possess robust open-world capabilities but also learn rich 3D geometric priors. For instance, Stable Diffusion [53  ###reference_b53###], can be finetuned to include camera view control [35  ###reference_b35###, 62  ###reference_b62###, 60  ###reference_b60###, 28  ###reference_b28###, 36  ###reference_b36###, 38  ###reference_b38###], enabling it to predict novel views of objects\u2014a task that necessitates significant 3D spatial reasoning. Consequently, we are inspired to utilize the rich priors inherent in 2D diffusion models for the tasks of sparse view 3D reconstruction and pose estimation.\nUnlike most existing approaches that use a single RGB image as the condition and focus on synthesizing multi-view images, our goal is to take a sparse set of input images and stimulate Stable Diffusion to infer the spatial relationships among the input views implicitly. To accomplish this, given  sparse views from arbitrary camera poses, we tile them into a  multi-view grid, as illustrated in Fig. 3  ###reference_### (c). The image in the first grid cell determines a canonical frame (to be discussed later), while the order of the other views is inconsequential. When there are fewer than 6 sparse views, we use empty padding for the remaining grid cells. This composite image then serves as the condition for Stable Diffusion, which is expected to assimilate all information from the input sparse views during the diffusion process.\nWe employ Stable Diffusion 2.1 as our base model. To adapt the original text-conditioning to our tiled multi-view image condition, we follow [60  ###reference_b60###] to apply both local and global conditioning strategies. For local conditioning, we use the reference-only attention mechanism [96  ###reference_b96###], where we process the reference tiled image with the denoising UNet model and append the attention keys and values from this image to corresponding layers in the denoising model for the target images. This mechanism facilitates implicit yet effective interactions between the diffusion model and the sparse views. For global conditioning, we integrate the mean-pooled CLIP embedding of all input images\u2014modulated by learnable token weights\u2014into the diffusion process, enhancing the model\u2019s ability to grasp the overarching semantics and structure of the sparse views.\nAs depicted in Figs. 2  ###reference_### and 3  ###reference_###, our objective is to concurrently generate grid images for both NOCS maps of the input views and multi-view images from known camera poses. To achieve this, we utilize a domain switcher [38  ###reference_b38###] that enables flexible toggling between the two domains. The switcher consists of two learnable embeddings, one for each domain, which are then injected into the UNet of the stable diffusion models by being added to its time embedding."

However, in scenarios with sparse views, there may be little to no overlap between input views. The lack of sufficient visual correspondence cues often renders the solvers unreliable and prone to failure. Consequently, instead of relying on local correspondences, we leverage the rich semantic priors embedded in 2D diffusion models for pose estimation.\nOne of the primary challenges is to enable 2D diffusion models to output camera poses. While camera poses can be represented in various scalar formats (e.g., 6-dimensional vector, four-by-four matrix, etc.), they are not native representations for a 2D diffusion model to generate. Inspired by recent works demonstrating that 2D diffusion models can be used to predict normal maps [38  ###reference_b38###]\u2014a domain different from natural images\u2014we propose using a surrogate representation: the Normalized Object Coordinate Space (NOCS) [74  ###reference_b74###]. We finetune Stable Diffusion to predict NOCS maps for each input view.\nAs depicted in Fig. 3  ###reference_###(b), a NOCS frame is determined for each set of input sparse view images and the underlying 3D object. Specifically, the 3D shape is normalized into a unit cube, i.e., . The shape\u2019s upward axis aligns with the dataset\u2019s inherent upward axis of the 3D object, typically the gravity axis. Predicting the object\u2019s forward-facing direction may be ambiguous, so we rotate the 3D shape in the NOCS frame to align its forward direction (zero azimuth) with that of the first input view, thus unambiguously establishing the NOCS frame. For each input view, we then render a NOCS map, where each 2D pixel (r,g,b) represents the corresponding 3D point\u2019s position (x,y,z) in the defined NOCS frame, as shown in Fig. 3  ###reference_###(c). These NOCS maps align with the operational domain of 2D diffusion models, similar to the normal maps in previous work [38  ###reference_b38###].\nTo facilitate interactions between NOCS maps from different views and generate more 3D-consistent NOCS maps, we tile all NOCS maps into a  grid image as the input condition (see Sec. 3.1  ###reference_###), following the same tiling order and the empty padding convention. We finetune Stable Diffusion to generate these multi-view tiled NOCS maps, so the 2D diffusion model can attend to both the input sparse views and their NOCS maps during the diffusion process.\nAfter generating the NOCS maps for the input sparse views, we employ a traditional Perspective-n-Point (PnP) solver [2  ###reference_b2###] to compute the poses  from the NOCS frame to the camera frames of each input view by minimizing the reprojection error:\nwhere  represents the  pixel\u2019s location in the  NOCS map;  is the corresponding 3D point location in the NOCS frame;  is the number of pixels for the  view, and proj is the perspective projection operation. Note that the PnP algorithm assumes known camera intrinsics and optimizes only for the camera extrinsics. A RANSAC scheme is applied during the PnP computation for outlier removal, enhancing the robustness of the pose prediction to boundary noises and errors from the 2D diffusion model. As all NOCS maps share a common NOCS frame, we can thus determine the relative camera poses between views  and  through ."

It is noteworthy that the input sparse views might not encompass the entire 3D objects, nor provide adequate information for 3D reconstruction. Therefore, we propose to predict multi-view images at uniformly distributed camera poses first, and then use these predicted images for 3D reconstruction.\nUnlike traditional novel view synthesis [35  ###reference_b35###], our approach employs a fixed camera configuration for target multi-views. As depicted in Fig. 3  ###reference_###, our target multi-view images consist of six views with alternating  and  elevations, and -spaced azimuths relative to the first input view. Although the elevation angles are set absolutely, the azimuth angles are relative to the azimuth of the first input sparse view to resolve the ambiguity in face-forwarding directions. Furthermore, We maintain consistent camera intrinsics across target views, independent of input views. These strategies mitigate challenges in predicting camera intrinsics and elevation during the 3D reconstruction process. Existing methods hindered by this issue may be sensitive to intrinsic variations and often depend on predicting [34  ###reference_b34###] or requiring user-specified [36  ###reference_b36###, 66  ###reference_b66###, 65  ###reference_b65###] input image elevations.\nSimilar to NOCS map prediction, we tile all six views into a  grid image and finetune Stable Diffusion to generate this tiled image. The 2D diffusion model, conditioned on the input sparse views, aims to incorporate all information from input views, deduce the underlying 3D objects, and predict the multi-view images at the predetermined camera poses. Although the predicted poses of input sparse views (Sec. 3.2  ###reference_###) are not directly employed in the 3D reconstruction, the joint training of NOCS prediction and multi-view prediction branches implicitly complement each other and boost the performance of both tasks.\nUpon generating the multi-view images at known camera poses, we utilize the multi-view to 3D reconstruction module proposed in [32  ###reference_b32###] to lift these images to 3D. The reconstruction module adopts a two-stage coarse-to-fine approach, which involves initially extracting the 2D features of the generated multi-view images, aggregating them with the known camera poses, and constructing a 3D cost volume. This 3D cost volume acts as the condition for the 3D diffusion networks. In the coarse stage, a low-resolution  3D occupancy volume is produced. This is subsequently refined to yield a high-resolution  SDF (Signed Distance Field) volume with colors. Finally, a textured mesh is derived from the SDF volume employing the marching cubes algorithm."

The generated 3D mesh , though not perfect, provides a multi-view consistent and explicit 3D structure. We can further refine the coarse poses predicted from the NOCS maps by leveraging the reconstructed 3D shape.\nPose Refinement via Differentiable Rendering.\nStarting with initial poses  extracted from the predicted NOCS maps, we refine them through differentiable rendering [26  ###reference_b26###]. Specifically, we render the generated mesh  at optimizing camera poses . We minimize the rendering loss between the rendered image  and the input image  to obtain the optimally fitted camera pose .

The NOCS pose predictions are inherently stochastic and may not produce an accurate pose in a single pass. For instance, with objects possessing certain symmetries, the diffusion model may predict only one of the possible symmetric poses. We employ a Mixture of Experts (MoE) strategy to further refine the pose, which is simple but effective. Specifically, we generate multiple NOCS maps for each input view using different seeds. We then select the pose that minimizes the rendering loss based on the refinement results with the generated 3D mesh. This technique effectively reduces pose estimation error, as quantitatively validated by the ablation study in the Appendix."

Considering the variable quality of the original Objaverse dataset, we opted to filter out higher-quality data by initially manually annotating 8,000 3D objects based on overall geometry quality and texture preferences. Subsequently, we train MLP models for quality rating classification and texture score regression, utilizing their multimodal features [33  ###reference_b33###]. Based on the predictions of these models, we select shapes that are rated as high-quality and have top texture scores. Further details about the data filtering process are included in the Appendix.\nFor each 3D shape, we render 10 sets of images using BlenderProc [11  ###reference_b11###]. Each set comprises 6 input images, 6 output multi-view images, and 6 NOCS maps. To mimic real-world conditions and ensure model robustness, we randomly sample camera intrinsics and extrinsics, as well as environment maps for the input images. For the output multi-view images, their intrinsics remain constant, while the extrinsics are derived from a fixed delta pose and the azimuth of the input images. Each set of input and output images shares the same environment map. During training, we randomly selected between 1 to 6 views as sparse input views, with the first view of each set always being included. We train the model utilizing 8 A100 GPUs for approximately 3 days.\n###figure_3### Baselines.\nFor 3D reconstruction, we compare our method with both state-of-the-art single-image-to-3D and sparse-view-to-3D baselines. Single-view-to-3D methods we evaluate include optimization-based approaches, such as Zero123 XL [8  ###reference_b8###], SyncDreamer [36  ###reference_b36###], and DreamGaussian [66  ###reference_b66###], as well as feed-forward methods like One-2-3-45 [34  ###reference_b34###] and Shap-E [20  ###reference_b20###]. For sparse-view methods, we consider two recent open-source approaches as baselines: iFusion [83  ###reference_b83###] and EscherNet [23  ###reference_b23###]. We utilize ThreeStudio [13  ###reference_b13###]\u2019s implementation for Zero123 XL and the official implementations for the other baselines. Specifically, for iFusion, we use their official reconstruction pipeline integrated with Zero123 XL.\nFor sparse-view pose estimation, we compare our method with state-of-the-art approaches including RelPose++ [29  ###reference_b29###], FORGE [17  ###reference_b17###], and iFusion [83  ###reference_b83###]. The latter two are optimization-based while [29  ###reference_b29###] is a feed-forward method.\nEvaluation Datasets.\nFor 3D reconstruction, we evaluate the methods on the entire GSO [12  ###reference_b12###] dataset, which comprises 1,030 3D shapes; none of these shapes were seen during our training. For each 3D shape, we randomly render six views as input images. For single-image-to-3D methods, a fixed-view image is taken as input following [34  ###reference_b34###]. We carefully align the predictions with the ground truth meshes before calculating the metrics. Please refer to the Appendix for detailed information on shape alignment and the evaluation metrics.\nFor pose estimation, we evaluate the approaches on three datasets: OmniObject3D [85  ###reference_b85###] and GSO [12  ###reference_b12###], both captured from real scans, and ABO [7  ###reference_b7###], a synthetic dataset created by artists. For each dataset, we randomly choose 500 objects and render five random sparse views per shape.

With only one initial pose (), it also fails to produce adequate results. In contrast, our method leverages priors from 2D diffusion models and can generate acceptable results in a single forward pass. Even without any additional refinement (w/o refine), our method can already produce results similar to iFusion with four initial poses (), while being far more efficient, requiring just 1/25 of the runtime. With the integration of further refinement through a mixture of experts, our method achieves even better performance.\n3D Reconstruction.\nWe present the qualitative results in Fig. 4  ###reference_###. With only a single-view input, single-image-to-3D methods fail to produce meshes that faithfully match the entire structure and details of the ground truth mesh. For instance, most single-view baseline methods are unable to reconstruct the stems of the artichoke, the back of the firetruck, the red saddle on Yoshi, and the two separate legs of Kirby standing on the ground. In contrast, sparse-view methods yield results that are much closer to the ground truth by incorporating information from multiple sparse views. Compared to iFusion, EscherNet, our method generates meshes with higher-quality geometry and textures that more accurately match the input sparse views. We report the quantitative results in Tab. 2  ###reference_###, where our method significantly outperforms both single-view-to-3D and sparse-view approaches in terms of both 2D and 3D metrics.

Fig. 6  ###reference_### showcases the predicted poses before and after refinement. Although both are generally very close to the ground truth poses, refinement can further reduce the error.\nNumber of Experts. We employ a mixture-of-experts strategy to address the ambiguity issues related to NOCS prediction for symmetric objects. By using this strategy and increasing the number of experts, there is a substantial increase in pose estimation accuracy. Please refer to the Appendix for more details and quantitative ablation studies.\nJoint Training. We finetune 2D diffusion models to jointly predict NOCS maps and multi-view images from sparse, unposed views by leveraging a domain switcher. As shown in Tab. 4  ###reference_###, this joint training strategy enables the two branches to implicitly interact and complement each other, enhancing the interpretation of both the input sparse views and the intrinsic properties of the 3D objects, which in turn improves the performance of each task."

During the alignment process, we sample 12 rotations ( apart) as initial positions and 10 scales from 0.6 to 1.4, which is dense enough in practice. We enumerate the combinations of these rotations and scales for initialization and subsequently refine the alignment with the Iterative Closest Point (ICP) algorithm. We select the alignment that yields the highest inlier ratio. Both the ground truth and predicted meshes are then scaled to fit within a unit bounding box.\nWe adopt the evaluation metrics from [32  ###reference_b32###] to assess the reconstruction quality from two perspectives: (1) geometric quality and (2) texture quality. For geometric quality, we apply the F-score to quantify the discrepancy between the reconstructed and ground truth meshes, setting the F-score threshold at 0.05. To evaluate texture quality, we compute the CLIP-Similarity, PSNR, and LPIPS between images rendered from the reconstructed mesh and those of the ground truth. The meshes undergo rendering from 24 distinct viewpoints, encompassing a full 360-degree view around the object. The rendered images have a resolution of 512  512 pixels.\nTo evaluate pose estimation, we render five sparse views for each shape and assess the relative poses between all ten pairs of views. We convert the predicted poses to the OpenCV convention and report the median rotation error, rotation accuracy, and translation error across all pairs. The rotation error is the minimum angular deviation between the predicted and the ground truth poses. In contrast, the translation error is the absolute difference between the corresponding translation vectors. We present accuracies as the percentage of pose pairs with rotation errors below the thresholds of 15\u2218 and 30\u2218.\nIt should be noted that iFusion [83  ###reference_b83###] infers only the relative elevation, azimuth, and distance, and cannot provide the 4x4 camera matrix without the absolute camera pose of the reference image. For iFusion, we supplement the elevation angle of the reference image using an external elevation estimation method [34  ###reference_b34###], which has a median prediction error of 5\u2218 on the GSO dataset. Additionally, many baseline methods do not require camera intrinsics as input, resulting in predicted poses with varying distances from the camera to the shape, as reflected by the magnitude of the translation vectors. To address this intrinsic ambiguity, we normalize the predicted translation vectors for each method by using a scale factor that aligns the first view\u2019s predicted camera translation with the ground truth translation. After normalization, we report the absolute translation errors.

We begin by randomly selecting a subset of 3D models and then task annotators with assessing the overall geometry quality and evaluating texture aesthetic preferences. Subsequently, we train a simple network to predict such annotations.\nFor assessing overall geometry quality, annotators are required to assign one of three possible levels to each 3D model:\nHigh quality: Objects that represent a single entity with a clear semantic meaning, such as avatars and animals.\nMedium quality: Simple geometric shapes (e.g., cubes, spheres); geometries that are abstract or have unclear semantic meaning; and repetitive structures found in the Objaverse, such as skeletal frames of houses and staircases.\nLow quality: Point clouds; scenes with multiple elements; incomplete, low-quality, or unidentifiable 3D scans.\nFor texture preference, given the difficulty in defining absolute standards due to aesthetic subjectivity, we adopt a binary choice approach for annotation. This method presents annotators with pairs of 3D models, prompting them to select the one with superior texture quality or visual appeal.\nOverall, we have recruited 10 annotators and collected labels for 4,000 pairs of shapes in total. Based on these annotations, we trained MLP networks to predict overall geometry quality ratings and texture scores, respectively. Both networks take the multimodal features of each shape as input, which include image, text, and 3D features, as encoded in OpenShape [33  ###reference_b33###]. The rating classification MLP predicts a one-hot encoded label across three levels, and is trained using the cross-entropy loss.

Much of this progress has been fueled by distributed training, yet distributed communication remains a substantial bottleneck to training progress.\nThis paper examines the communication behavior of transformer models \u2014 that is, how different parallelism schemes used in multi-node/multi-GPU DL Training communicate data in the context of transformers. We use GPT-based language models as a case study of the transformer architecture due to their ubiquity. We validate the empirical results obtained from our communication logs using analytical models. At a high level, our analysis reveals a need to optimize small message point-to-point communication further, correlations between sequence length, per-GPU throughput, model size, and optimizations used, and where to potentially guide further optimizations in framework and HPC middleware design and optimization.",

LLMs are typically pre-trained with internet-scale, pre-processed data that allows them to learn the intricacies of human languages. After pre-training, LLMs undergo a fine-tuning process in a supervised setting that allows them to excel in downstream tasks like generation, summarization, translation, and question/answering. Modern LLMs utilize a large number of parameters that imply increased computational and memory requirements during training. A higher number of parameters allows the model to capture more intricate relationships and nuances in language, leading to improved performance on a range of downstream tasks."

The original transformer architecture is designed for machine translation and contains two main components: an Encoder and a Decoder. Modern adaptations of transformers for language modeling utilize either the Encoder or Decoder depending on the specific task, such as BERT [17  ###reference_b17###] and GPT-2 [18  ###reference_b18###].\nA transformer layer is structured with a self-attention block followed by a two-layer multi-layer perceptron (MLP), composed of two GEMMs and a GeLU non-linearity (ReLU for the original version [16  ###reference_b16###]). Each encoder or decoder block includes multiple such layers, each featuring multi-head attention, MLP, normalization, and residual connections.\nWe consider a single encoder or decoder with multiple transformer layers. Initially, input tokens are processed through a word embedding table and combined with positional embeddings, resulting in a 3-D tensor of size (sequence length \u00d7 micro-batch size \u00d7 hidden dimension) [19  ###reference_b19###]. Each transformer layer processes this tensor through a self-attention block with multiple attention heads and a two-layer MLP that quadruples the hidden size and then reduces it back. The output size remains consistent across layers, and the final output is projected back to the vocabulary dimension for cross-entropy loss calculation."

Training billion/trillion-parameter transformer models is a memory-intensive task since it requires efficient distribution of multiple training parameters (model weights, optimizer states, gradients, and activations).\nIn Data Parallelism [22  ###reference_b22###], a training mini-batch is divided among multiple workers and each worker maintains a full model replica. Data parallelism can achieve near-linear scaling in training data throughput by increasing the mini-batch size in proportion to the number of available workers. Typically, an Allreduce on all the workers is required to synchronize the gradients before updating the model weights on each local replica. Data Parallelism is communication-bound since the achievable bandwidth and latency of the Allreduce greatly affect iteration time given a worker\u2019s memory is consumed by the model and other training parameters. However, data parallelism requires that model size must fit in the limited GPU memory and additional optimizer and hyper-parameter tuning to ensure convergence with large global batch size [23  ###reference_b23###].\nPipeline Parallelism mainly focuses on distributing layers of models among GPU workers and executes these layers in a pipeline order. Since activation computation relies on dependencies between different layers, inevitable GPU idle times, known as pipeline bubbles are present in this paradigm, there have been various research efforts in reducing such bubbles [24  ###reference_b24###, 25  ###reference_b25###]. In terms of communication, pipeline parallelism involves point-to-point GPU communication to pass along activations between layers.\nTensor Parallelism [26  ###reference_b26###] aims at exploiting the inherent parallelism inside GEMM operations and distribute these computations along specific directions (rows, columns) and use synchronization among workers to gather the results, thus ensuring correctness. State-of-the-art implementations distribute the MLP blocks and Self-Attention blocks [26  ###reference_b26###]. Results are collected and aggregated using Allreduce and Allgather. It is a common practice to limit tensor parallelism degree within a compute node since intra-node bandwidth is typically larger than inter-node bandwidth [27  ###reference_b27###].\nFigure 4  ###reference_### demonstrates 3D Parallelism, which combines Data Parallelism, Pipeline Parallelism and Tensor Parallelism. This synergy has been a widely adopted approach to scale up transformer training to thousands of workers. It has the benefit of preventing global batch size from growing atrociously but requires effort to implement and prototype.\n###figure_4###"

[28  ###reference_b28###] Zero Redundancy Optimizer (ZeRO) reduces memory constraints by removing redundant information, and partitioning model data across data parallel ranks. ZeRO is divided into three stages, ZeRO-1, ZeRO-2, and ZeRO-3.\n###figure_5### Given a certain degree of data parallelism, each ZeRO stage partitions different training parameters. ZeRO-1 partitions optimizer states across workers. Each worker only needs to store and update its partitions. At the end of each training step, an allgather is required to collect the fully updated model weights. ZeRO-2 further partitions gradients and reduces them to only update the corresponding parameters. After gradient reduction, the memory can be released immediately, which will further alleviate memory pressure on a worker. Such a process requires Reduce-Scatter to distribute and reduce the gradients. ZeRO-1 and ZeRO-2 produce the same communication volume as standard data parallelism [28  ###reference_b28###]. ZeRO-3 applies model parameter partitioning on top of optimizer states and gradients. However, stage 3 requires an extra allgather to collect parameters from all other processes as needed in forward and backward computation which typically incurs 1.5x communication volume compared to data parallelism baseline (Figure 5  ###reference_###).\nZeRO++ applies various optimizations towards ZeRO-3, aiming at reducing communication volume and featuring a bandwidth-aware partitioning strategy. Specifically, ZeRO++ integrates blocked-based quantization kernels [29  ###reference_b29###] into model weights and gradient communications to drastically reduce message size. It also keeps a secondary parameter partition within a compute node so that high-latency inter-node Allgather can be avoided due to low interconnect bandwidth [30  ###reference_b30###]."

The main takeaway: Even though DL models such as LLMs operate using massive message sizes, optimizations at smaller message sizes should be treated as equally important.\n###figure_15### ###figure_16### ###figure_17###"

While raw performance modeling is outside the scope of this paper, it is important to note that this anomaly becomes a concern as model size increases and pipeline parallelism is used.

To reduce redundancy, we will note that this does not change across increasing sequence length values, from 512 to 4096 or higher. However, we do note that optimizations and sequence length do have an impact on throughput. Figure 14(b)  ###reference_.sf2### shows how different levels of ZeRO impact throughput. While we see an approximate 2-2.5x increase in TFlops per GPU, ZeRO optimizations will more often than not result in a decrease of flops for the given sequence length.\nCompared to data parallelism and ZeRO, there is more variation in the \u201ckey\u201d components tensor/pipeline/model parallelism. While pure tensor parallelism makes sole use of Allreduce, pure pipeline parallelism and model parallelism make use of point-to-point operations as well, and contrary to the above, these volumes increase with token size (see Sections III  ###reference_### and V-B  ###reference_###). Figure 15(b)  ###reference_.sf2### shows an approximate doubling/slightly-larger-than-2x increase in communication volume with increasing sequence-length values while Figure 15(a)  ###reference_.sf1### directly shows a 2x increase with increasing sequence-length values. Similar to the data-parallel results, we also see an increase in throughput as shown in figure 15(c)  ###reference_.sf3###. For brevity, we only show when we have two pipeline stages or a tensor parallelism value of two. Ultimately, the use of tensor parallelism will allow for a higher TFLOP-per-GPU count over pipeline parallelism (up to almost 2x more), though this has an inverse relationship with point-to-point communication (where applicable as pure tensor parallelism does not use point-to-point) in communication volume.\n###figure_30### ###figure_31### ###figure_32###"

+    "abstract": "Open-world 3D reconstruction models have recently garnered significant attention. However, without sufficient 3D inductive bias, existing methods typically entail expensive training costs and struggle to extract high-quality 3D meshes. In this work, we introduce MeshFormer, a sparse-view reconstruction model that explicitly leverages 3D native structure, input guidance, and training supervision. Specifically, instead of using a triplane representation, we store features in 3D sparse voxels and combine transformers with 3D convolutions to leverage an explicit 3D structure and projective bias. In addition to sparse-view RGB input, we require the network to take input and generate corresponding normal maps. The input normal maps can be predicted by 2D diffusion models, significantly aiding in the guidance and refinement of the geometry\u2019s learning. Moreover, by combining Signed Distance Function (SDF) supervision with surface rendering, we directly learn to generate high-quality meshes without the need for complex multi-stage training processes. By incorporating these explicit 3D biases, MeshFormer can be trained efficiently and deliver high-quality textured meshes with fine-grained geometric details. It can also be integrated with 2D diffusion models to enable fast single-image-to-3D and text-to-3D tasks.",

+            "text": "High-quality 3D meshes are essential for numerous applications, including rendering, simulation, and 3D printing. Traditional photogrammetry systems [57  ###reference_b57###, 61  ###reference_b61###] and recent neural approaches, such as NeRF [43  ###reference_b43###], typically require a dense set of input views of the object and long processing times. Recently, open-world 3D object generation has made significant advancements, aiming to democratize 3D asset creation by reducing input requirements. There are several prevailing paradigms: training a native 3D generative model using only 3D data [13  ###reference_b13###, 95  ###reference_b95###] or performing per-shape optimization with Score Distillation Sampling (SDS) losses [47  ###reference_b47###, 30  ###reference_b30###]. Another promising direction is to first predict a sparse set of multi-view images using 2D diffusion models [33  ###reference_b33###, 59  ###reference_b59###] and then lift these predicted images into a 3D model by training a feed-forward network [32  ###reference_b32###, 31  ###reference_b31###]. This strategy addresses the limited generalizability of models trained solely on 3D data and overcomes the long runtime and 3D inconsistency of per-shape-optimization-based methods.\nWhile many recent works explore utilizing priors from 2D diffusion models, such as generating consistent multi-view images [60  ###reference_b60###, 59  ###reference_b59###] and predicting normal maps from RGB [37  ###reference_b37###, 12  ###reference_b12###, 59  ###reference_b59###], the feed-forward model that converts multi-view images into 3D remains underexplored. One-2-3-45 [32  ###reference_b32###] leverages a generalizable NeRF method for 3D reconstruction but suffers from limited quality and success rates. One-2-3-45++ [31  ###reference_b31###] improves on this by using a two-stage 3D diffusion model, yet it still struggles to generate high-quality textures or fine-grained geometry. Given that sparse-view reconstruction of open-world objects requires extensive priors, another family of works pioneered by the large reconstruction model (LRM) [16  ###reference_b16###] combines large-scale transformer models with the triplane representation and trains the model primarily using rendering loss. Although straightforward, these methods typically require over a hundred GPUs to train. Moreover, due to their reliance on volume rendering, these methods have difficulty extracting high-quality meshes. For instance, some recent follow-up works [85  ###reference_b85###, 79  ###reference_b79###] implement complex multi-stage \u201cNeRF-to-mesh\u201d training strategies, but the results still leave room for improvement.\nIn this work, we present MeshFormer, an open-world sparse-view reconstruction model that takes a sparse set of posed images of an arbitrary object as input and delivers high-quality 3D textured meshes with a single forward pass in a few seconds. Instead of representing 3D data as \u201c2D planes\u201d and training a \u201cblack box\u201d transformer model optimizing only rendering loss, we find that by incorporating various types of 3D-native priors into the model design, including network architecture, supervision signals, and input guidance, our model can significantly improve both mesh quality and training efficiency. Specifically, we propose representing features in explicit 3D voxels and introduce a novel architecture that combines large-scale transformers with 3D (sparse) convolutions. Compared to triplanes and pure transformers models with little 3D-native design, MeshFormer leverages the explicit 3D structure of voxel features and the precise projective correspondence between 3D voxels and 2D multi-view features, enabling faster and more effective learning.\nUnlike previous works that rely on NeRF-based representation in their pipeline, we utilize mesh representation throughout the process and train MeshFormer in a unified, single-stage manner. Specifically, we propose combining surface rendering with additional explicit 3D supervision, requiring the model to learn a signed distance function (SDF) field. The network is trained with high-resolution SDF supervision, and efficient differentiable surface rendering is applied to the extracted meshes for rendering losses. Due to the explicit 3D geometry supervision, MeshFormer enables faster training while eliminating the need for expensive volume rendering and learning an initial coarse NeRF. Furthermore, in addition to multi-view posed RGB images, we propose using corresponding normal maps as input, which can be captured through sensors and photometric techniques [82  ###reference_b82###, 4  ###reference_b4###] or directly estimated by recent 2D vision models [59  ###reference_b59###, 37  ###reference_b37###, 12  ###reference_b12###]. These multi-view normal images provide important clues for 3D reconstruction and fine-grained geometric details. We also task the model with learning a normal texture in addition to the RGB texture, which can then be used to enhance the generated geometry through a traditional post-processing algorithm [44  ###reference_b44###].\nThanks to the explicit 3D-native structure, supervision signal, and normal guidance that we have incorporated, MeshFormer can generate high-quality textured meshes with fine-grained geometric details, as shown in Figure LABEL:fig:teaser. Compared to concurrent methods that require over one hundred GPUs or complex multi-stage training, MeshFormer can be trained more efficiently and conveniently with just eight GPUs over two days, achieving on-par or even better performance. It can also seamlessly integrate with various 2D diffusion models to enable numerous tasks, such as single-image-to-3D and text-to-3D. In summary, our key contributions include:\nWe introduce MeshFormer, an open-world sparse-view reconstruction model capable of generating high-quality 3D textured meshes with fine-grained geometric details in a few seconds. It can be trained with only 8 GPUs, outperforming baselines that require over one hundred GPUs.\nWe propose a novel architecture that combines 3D (sparse) convolution and transformers. By explicitly leveraging 3D structure and projective bias, it facilitates better and faster learning.\nWe propose a unified single-stage training strategy for generating high-quality meshes by combining surface rendering and explicit 3D geometric supervision.\nWe are the first to introduce multi-view normal images as input to the feed-forward reconstruction network, providing crucial geometric guidance. Additionally, we propose to predict extra 3D normal texture for geometric enhancement."

Exemplified by DreamFusion [47  ###reference_b47###], a line of work [70  ###reference_b70###, 10  ###reference_b10###, 26  ###reference_b26###, 58  ###reference_b58###, 6  ###reference_b6###, 76  ###reference_b76###, 48  ###reference_b48###, 62  ###reference_b62###, 60  ###reference_b60###, 30  ###reference_b30###, 5  ###reference_b5###, 65  ###reference_b65###] uses 2D models as guidance to generate 3D objects through per-shape optimization with SDS-like losses. Although these methods produce increasingly better results, they are still limited by lengthy runtimes and many other issues. Another line of work [45  ###reference_b45###, 20  ###reference_b20###, 40  ###reference_b40###, 84  ###reference_b84###, 16  ###reference_b16###, 96  ###reference_b96###] trains a feed-forward generative model solely on 3D data that consumes text prompts or single-image inputs. While fast during inference, these methods struggle to generalize to unseen object categories due to the scarcity of 3D data. More recently, works such as Zero123 [33  ###reference_b33###] have shown that 2D diffusion models can be fine-tuned with 3D data for novel view synthesis. A line of work [31  ###reference_b31###, 27  ###reference_b27###, 85  ###reference_b85###, 27  ###reference_b27###, 79  ###reference_b79###, 77  ###reference_b77###, 64  ###reference_b64###], pioneered by One-2-3-45 [32  ###reference_b32###], proposes first predicting multi-view images through 2D diffusion models and then lifting them to 3D through a feed-forward network, effectively addressing the speed and generalizability issues. Many recent works have also explored better strategies to fine-tune 2D diffusion models for enhancing the 3D consistency of multi-view images [60  ###reference_b60###, 34  ###reference_b34###, 80  ###reference_b80###, 89  ###reference_b89###, 59  ###reference_b59###, 17  ###reference_b17###, 91  ###reference_b91###, 36  ###reference_b36###, 81  ###reference_b81###, 69  ###reference_b69###, 14  ###reference_b14###, 49  ###reference_b49###, 23  ###reference_b23###, 72  ###reference_b72###]. In addition to the feed-forward models, the generated multi-view images can also be lifted to 3D through optimizations [37  ###reference_b37###, 14  ###reference_b14###, 34  ###reference_b34###].\nSparse-View Feed-Forward Reconstruction Models\nWhen a small baseline between input images is assumed, existing generalizable NeRF methods [52  ###reference_b52###, 68  ###reference_b68###, 35  ###reference_b35###, 88  ###reference_b88###] aim to find pixel correspondences and learn generalizable priors across scenes by leveraging cost-volume-based techniques [3  ###reference_b3###, 90  ###reference_b90###, 38  ###reference_b38###] or transformer-based structures [74  ###reference_b74###, 24  ###reference_b24###, 71  ###reference_b71###, 19  ###reference_b19###, 54  ###reference_b54###]. Some of methods have also incorporated a 2D diffusion process into the pipeline [1  ###reference_b1###, 66  ###reference_b66###, 21  ###reference_b21###]. However, these methods often struggle to handle large baseline settings (e.g., only frontal-view reconstruction) or are limited by a small training set and fail to generalize to open-world objects. Recently, many models [94  ###reference_b94###, 77  ###reference_b77###, 64  ###reference_b64###, 27  ###reference_b27###, 86  ###reference_b86###, 79  ###reference_b79###, 92  ###reference_b92###, 85  ###reference_b85###, 73  ###reference_b73###, 87  ###reference_b87###] specifically aimed at open-world 3D object generation have been proposed. They typically build large networks and aim to learn extensive reconstruction priors by training on large-scale 3D datasets [9  ###reference_b9###]. For example, the triplane representation and transformer models are often used. By applying volume rendering or Gaussian splatting [64  ###reference_b64###, 86  ###reference_b86###, 92  ###reference_b92###], they train the model with rendering losses. However, these methods typically require extensive GPUs to train and have difficulty extracting high-quality meshes. While some recent (concurrent) works [85  ###reference_b85###, 79  ###reference_b79###] utilize multi-stage \u201cNeRF-to-mesh\u201d training strategies to improve the quality, the results still leave room for improvement.\nGeometry Guidance for 3D Reconstruction Many recent works have shown that in addition to multi-view RGB images, 2D diffusion models can be fine-tuned to generate other geometric modalities, such as depth maps [75  ###reference_b75###], normal maps [37  ###reference_b37###, 41  ###reference_b41###, 12  ###reference_b12###], or coordinate maps [28  ###reference_b28###, 77  ###reference_b77###]. These additional modalities can provide crucial guidance for 3D generation and reconstruction. While many recent methods utilize these geometric cues as inverse optimization guidance [49  ###reference_b49###, 5  ###reference_b5###, 37  ###reference_b37###, 12  ###reference_b12###, 28  ###reference_b28###, 77  ###reference_b77###], we propose to take normal maps as input in a feed-forward reconstruction model and task the model with generating 3D-consistent normal texture for geometry enhancement of sharp details.\n3D Native Representations and Network Architectures in 3D Generation\nThe use of 3D voxel representations and 3D convolutions is common in general 3D generation. However, most recent works focus on 3D-native diffusion [53  ###reference_b53###, 29  ###reference_b29###, 7  ###reference_b7###, 95  ###reference_b95###, 31  ###reference_b31###, 18  ###reference_b18###], one of the key paradigms in 3D generation, which differs from the route taken by MeshFormer. These 3D-diffusion-based methods have some common limitations. For instance, they focus solely on geometry generation and cannot directly predict high-quality textures from the network [53  ###reference_b53###, 29  ###reference_b29###, 7  ###reference_b7###, 95  ###reference_b95###, 31  ###reference_b31###, 18  ###reference_b18###]. Due to the limited availability of 3D data, 3D-native diffusion methods also typically struggle with open-world capabilities and are often constrained to closed-domain datasets (e.g., ShapeNet [2  ###reference_b2###]) in their experiments [29  ###reference_b29###, 7  ###reference_b7###, 95  ###reference_b95###].\nIn MeshFormer, our goal is to achieve direct high-quality texture generation while handling arbitrary object categories. Therefore, we adopt a different approach: sparse-view feed-forward reconstruction, as opposed to 3D-native diffusion. In this specific task setting, more comparable works are recent LRM-style methods [85  ###reference_b85###, 79  ###reference_b79###, 64  ###reference_b64###, 67  ###reference_b67###]. However, most of these methods rely on a combination of triplane representation and large-scale transformers. In this paper, we demonstrate that 3D-native representations and networks can not only be used in 3D-native diffusion but can also be combined with differentiable rendering to train a feed-forward sparse-view reconstruction model using rendering losses. In open-world sparse-view reconstruction, we are not limited to the triplane representation. Instead, 3D-native structures (e.g., voxels), network architectures, and projective priors can facilitate more efficient training, significantly reducing the required training resources. While scalable networks are necessary to learn extensive priors, scalability is not exclusive to triplane-based transformers. By integrating 3D convolutions with transformer layers, scalability can also be achieved."

Prior arts [27  ###reference_b27###, 79  ###reference_b79###, 85  ###reference_b85###, 67  ###reference_b67###, 77  ###reference_b77###] typically utilize the triplane representation, which decomposes a 3D neural field into a set of 2D planes. While straightforward for processing by transformers, the triplane representation lacks explicit 3D spatial structures and makes it hard to enable precise interaction between each 3D location and its corresponding 2D projected pixels from multi-view images. For instance, these methods often simply apply self-attention across all triplane patch tokens and cross-attention between triplane tokens and all multi-view image tokens. This all-to-all attention is not only costly but also makes the methods cumbersome to train. Moreover, the triplane representation often shows results with notable artifacts at the boundaries of patches and may suffer from limited expressiveness for complex structures. Consequently, we choose the 3D voxel representation instead, which explicitly preserves the 3D spatial structures.\nCombining Transformer with 3D Convolution\nTo leverage the explicit 3D structure and the powerful expressiveness of a large-scale transformer model while avoiding an explosion of computational costs, we propose VoxelFormer and SparseVoxelFormer, which follow a 3D UNet architecture while integrating a transformer at the bottleneck. The overall idea is that we use local 3D convolution to encode and decode a high-resolution 3D feature volume, while the global transformer layer handles reasoning and memorizing priors for the compressed low-resolution feature volume. Specifically, as shown in Figure 1  ###reference_###, a 3D feature volume begins with a learnable token shared by all 3D voxels. With the 3D voxel coordinates, we can leverage the projection matrix to enable each 3D voxel to aggregate 2D local features from multi-view images via a projection-aware cross-attention layer. By iteratively performing projection-aware cross-attention and 3D (sparse) convolution, we can compress the 3D volume to a lower-resolution one. After compression, each 3D voxel feature then serves as a latent token, and a deep transformer model is applied to a sequence of all 3D voxel features (position encoded) to enhance the model\u2019s expressiveness. Finally, we use the convolution-based inverse upper branch with skip connection to decode a 3D feature volume with the initial high resolution.\nProjection-Aware Cross Attention\nRegarding 3D-2D interaction, the input multi-view RGB and normal images are initially processed by a 2D feature extractor, such as a trainable DINOv2 [46  ###reference_b46###], to generate multi-view patch features. While previous cost-volume-based methods [38  ###reference_b38###, 3  ###reference_b3###] typically use mean or max pooling to aggregate multi-view 2D features, these simple pooling operations might be suboptimal for addressing occlusion and visibility issues. Instead, we propose a projection-aware cross-attention mechanism to adaptively aggregate the multi-view features for each 3D voxel. Specifically, we project each 3D voxel onto the  views to interpolate  RGB and normal features. We then concatenate these local patch features with the projected RGB and normal values to form  2D features. In the projection-aware cross-attention module, we use the 3D voxel feature to calculate a query and use both the 3D voxel feature and the  2D features to calculate  keys and values. A cross-attention is then performed for each 3D voxel, enabling precise interaction between each 3D location and its corresponding 2D projected pixels, and allowing adaptive aggregation of 2D features, which can be formulated as:\nWhere  denotes a 3D voxel feature, and  denotes its projected 2D pixel feature from view , which is a concatenation of the RGB feature , the normal feature , and the RGB and normal values  and , respectively.\nCoarse-to-Fine Feature Generation\nAs shown in Fig. 1  ###reference_###, to generate a high-resolution 3D feature volume that captures the fine-grained details of 3D shapes, we follow previous work [95  ###reference_b95###, 31  ###reference_b31###] by employing a coarse-to-fine strategy. Specifically, we first use VoxelFormer, which is equipped with full 3D convolution, to predict a low-resolution (e.g., ), coarse 3D occupancy volume. Each voxel in this volume stores a binary value indicating whether it is close to the surface. The predicted occupied voxels are then subdivided to create higher-resolution sparse voxels (e.g., ). Next, we utilize a second module, SparseVoxelFormer, which features 3D sparse convolution [63  ###reference_b63###], to predict features for these sparse voxels. After this, we trilinearly interpolate the 3D feature of any near-surface 3D point, which encodes both geometric and color information, from the high-resolution sparse feature volume. The features are then fed into various MLPs to learn the corresponding fields."

However, extracting high-quality meshes from their results is often non-trivial. For example, directly applying Marching Cubes [39  ###reference_b39###] to density fields of learned NeRFs typically generates meshes with many artifacts. Recent methods [79  ###reference_b79###, 85  ###reference_b85###, 78  ###reference_b78###] have designed complex, multi-stage \u201cNeRF-to-mesh\u201d training with differentiable surface rendering, but the generated meshes still leave room for improvement. On the other hand, skipping a good initialization and directly learning meshes from scratch using purely differentiable surface rendering losses is also infeasible, as it is highly unstable to train and typically results in distorted geometry.\nIn this work, we propose leveraging explicit 3D supervision in addition to 2D rendering losses. As shown in Figure 1  ###reference_###, we task MeshFormer with learning a signed distance function (SDF) field supervised by a high-resolution (e.g., ) ground truth SDF volume. The SDF loss provides explicit guidance for the underlying 3D geometry and facilitates faster learning. It also allows us to use mesh representation and differentiable surface rendering from the beginning without worrying about good geometry initialization or unstable training, as the SDF loss serves as a strong regularization for the underlying geometry. By combining surface rendering with explicit 3D SDF supervision, we train MeshFormer in a unified, single-stage training process. As shown in Figure 1  ###reference_###, we employ three tiny MLPs that take as input the 3D feature interpolated from the 3D sparse feature volume to learn an SDF field, a 3D color texture, and a 3D normal texture. We extract meshes from the SDF volume using dual Marching Cubes [39  ###reference_b39###] and employ NVDiffRast [25  ###reference_b25###] for differentiable surface rendering. We render both the multi-view RGB and normal images and compute the rendering losses, which consist of both the MSE and perceptual loss terms. As a result, our training loss can be expressed as:\nwhere  and  are MSE losses for occupancy and SDF volumes, and  denotes the weight of each loss term. Note that we do not use mesh geometry to derive normal maps; instead, we utilize the learned normal texture from the MLP, which will be detailed later."

While many recent works [27  ###reference_b27###, 79  ###reference_b79###, 85  ###reference_b85###] attempt to employ large-scale models to learn mappings from RGB to geometric details, this typically requires significant computational resources. Additionally, these methods are primarily trained using 3D data, but it\u2019s still uncertain whether the scale of 3D datasets is sufficient for learning such extensive priors. On the other hand, unlike RGB images, normal maps explicitly encode geometric information and can provide crucial guidance for 3D reconstruction. Notably, open-world normal map estimation has achieved great advancements. Many recent works [59  ###reference_b59###, 12  ###reference_b12###, 37  ###reference_b37###] demonstrate that 2D diffusion models, trained on billions of natural images, embed extensive priors and can be fine-tuned to predict normal maps. Given the significant disparity in data scale between 2D and 3D datasets, it may be more effective to use 2D models first for generating geometric guidance.\nInput Normal Guidance\nAs shown in Figure 1  ###reference_###, in addition to multi-view RGB images, MeshFormer also takes multi-view normal maps as input, which can be generated using recent open-world normal estimation models [59  ###reference_b59###, 12  ###reference_b12###, 37  ###reference_b37###]. In our experiments, we utilize Zero123++ v1.2 [59  ###reference_b59###], which trains an additional ControlNet [93  ###reference_b93###] over the multi-view prediction model. The ControlNet takes multi-view RGB images, predicted by Zero123++, as a condition and produces corresponding multi-view normal maps, expressed in the camera coordinate frame. Given these maps, MeshFormer first converts them to a unified world coordinate frame, and then treats them similarly to the multi-view RGB images, using projection-aware cross-attention to guide 3D reconstruction. According to our experiments (Sec. 4.4  ###reference_###), the multi-view normal maps enable the networks to better capture geometry details, and thus greatly improve final mesh quality.\nGeometry Enhancement\nWhile the straightforward approach of deriving normal maps from the learned mesh and using a normal loss to guide geometry learning has been commonly used, we find that this approach makes our mesh learning less stable. Instead, we propose learning a 3D normal texture, similar to a color texture, using a separate MLP. By computing the normal loss for MLP-queried normal maps instead of mesh-derived normal maps, we decouple normal texture learning from underlying geometry learning. This makes the training more stable, as it is easier to learn a sharp 3D normal map than to directly learn a sharp mesh geometry. The learned 3D normal texture can be exported with the mesh, similar to the color texture, to support various graphics rendering pipelines. In applications that require precise 3D geometry, such as 3D printing, the learned normal texture can also be used to refine the mesh geometry with traditional algorithms. Specifically, during inference, after extracting a 3D mesh from the SDF volume, we utilize a post-processing algorithm [44  ###reference_b44###] that takes as input the 3D positions of the mesh vertices and the vertex normals estimated from the MLP. The algorithm adjusts the mesh vertices to align with the predicted normals in a few seconds, further enhancing the geometry quality and generating sharp geometric details, as shown in Figure 4  ###reference_###."

For the other methods, we utilized their official implementations. Please refer to the supplementary for details.\nSince input settings differ among the baselines, we evaluate all methods in a unified single-view to 3D setting.

For One-2-3-45++ [31  ###reference_b31###], InstantMesh [85  ###reference_b85###], MeshLRM [79  ###reference_b79###], and our MeshFormer, we first utilized Zero123++ [59  ###reference_b59###] to convert the input single-view image into multi-view images before 3D reconstruction.

Here, we highlight two additional advantages of using the explicit 3D voxel structure: training efficiency and the avoidance of \u201ctriplane artifacts\u201d. Without leveraging explicit 3D structure, existing triplane-based large reconstruction models require extensive computing resources for training. For example, TripoSR requires 176 A100 GPUs for five days of training. InstantMesh relies on OpenLRM [15  ###reference_b15###], which requires 128 A100 GPUs for three days of training. MeshLRM also utilizes similar resources during training. By utilizing explicit 3D structure and projective bias, our MeshFormer can be trained much more efficiently using only 8 GPUs. To better understand the gap, we trained both MeshLRM and our MeshFormer under very limited training resources, and the results are shown in Table 2  ###reference_###. When using only 8 GPUs for two days, we found that MeshLRM failed to converge and experienced significant performance degradation compared to the results shown in Table 1  ###reference_###, while our MeshFormer had already converged to a decent result, close to the fully-trained version, demonstrating superior training efficiency.\nWe observe that the triplane typically generates results with axis-aligned artifacts, as shown in Fig.2  ###reference_### (5th row, please zoom in). As demonstrated in the supplementary (Fig. 6  ###reference_###), these artifacts also cause difficulties for MeshLRM [79  ###reference_b79###] in capturing the words on objects. These limitations are likely caused by the limited number of triplane tokens (e.g., ), constrained by the global attention, which often leads to artifacts at the boundaries of the triplane patches. In contrast, MeshFormer leverages sparse voxels, supports a higher feature resolution of , and is free from such artifacts.\nNormal Input and SDF supervision As shown in Table 3  ###reference_### (a), the performance significantly drops when multi-view input normal maps are removed, indicating that the geometric guidance and clues provided by normal images are crucial for facilitating network training, particularly for local geometric details. In (f), we replace ground truth normal maps with normal predictions by Zero123++ [59  ###reference_b59###] and observe a notable performance gap compared to (g). This indicates that although predicted multi-view normal images can be beneficial, existing 2D diffusion models still have room for improvement in generating more accurate results. See supplementary for qualitative examples. As shown in (b), if we remove the SDF loss after the first epoch and train the network using only surface rendering losses, the geometry learning quickly deteriorates, resulting in poor geometry. This explains why existing methods [27  ###reference_b27###, 79  ###reference_b79###] typically employ complex multi-stage training and use volume rendering to learn a coarse NeRF in the initial stage. By leveraging explicit 3D SDF supervision as strong geometric regularization, we enable a unified single-stage training, using mesh as the only representation.\nProjection-Aware Cross-Attention and Transformer Layers We propose to utilize projection-\n###figure_4### aware cross-attention to precisely aggregate multi-view projected 2D features for each 3D voxel. In conventional learning-based multi-view stereo (MVS) methods [3  ###reference_b3###, 38  ###reference_b38###], average or max pooling is typically employed for feature aggregation. In Table 3  ###reference_### (d), we replace the cross-attention with a simple average pooling and we observe a significant performance drop. This verifies that projection-aware cross-attention provides a more effective way for 3D-2D interaction while simple average pooling may fail to handle the occlusion and visibility issues. In the bottleneck of the UNet, we treat all 3D (sparse) voxels as a sequence of tokens and apply transformer layers to them. As shown in row (c), after removing these layers, we observe a performance drop in metrics related to texture quality. This indicates that texture learning requires more extensive priors and benefits more from the transformer layers.\nGeometry Enhancement We propose to learn an additional normal map texture and apply a traditional algorithm as post-processing for geometry enhancement during inference. As shown in Figure 4  ###reference_###, the geometry enhancement aligns the mesh geometry with the learned normal texture and generates fine-grained sharp details. In some cases (such as the wolf), the meshes output by the network are already good enough, and the difference caused by the enhancement tends to be subtle. Row (e) also quantitatively verifies the effectiveness of the module."

In contrast, our method leverages sparse voxels and supports a much higher feature resolution of , making it free from such issues.\n###figure_7### In Figure 7  ###reference_###, we qualitatively demonstrate the effect of input normal maps. When the model is trained without multi-view normal maps, we find that the generated model can only capture the global 3D shape but fails to generate fine-grained geometric details. However, when the model is given predicted normal maps, the performance is significantly better, although there are still some small gaps when compared to the results of ground truth normals (see the bread hole of the toaster and the wheel of the tram). This indicates errors or inconsistencies from the 2D normal prediction models.\nWe propose asking the network to predict an additional normal texture, which can be used for further geometric enhancement by applying a traditional algorithm as post-processing. The geometric enhancement aims to align the mesh geometry with the predicted normal map by adjusting the vertex locations. However, the traditional algorithm we used cannot guarantee that the mesh normals will be fully aligned with the predicted normal maps after processing. This limitation arises because the algorithm operates in local space and avoids large vertex displacements. Moreover, the predicted normal maps may contain errors or inconsistencies, such as conflicting neighboring normals. The adopted algorithm is an iterative numerical optimization method and does not compute an analytic solution.\nHowever, we have quantitatively verified that the post-processing module can significantly improve normal consistency with the predicted normal map. For example, before post-processing, only 26.4% of mesh vertices had a normal angle error of less than 2 degrees. After post-processing, this number increased to 40.8%. For a 10-degree threshold, the ratio increases from 78.8% to 86.4%.

Table 5  ###reference_### presents a quantitative analysis of our mesh generation quality over the training period. We observe that performance improves rapidly and nearly converges, with only marginal changes occurring after the two-day training period.\nTraining Details:\nWe trained the model using a subset of 395k 3D shapes filtered from the Objaverse [9  ###reference_b9###] dataset. These objects have a distributable Creative Commons license and were obtained by the Objaverse team using Sketchfab\u2019s public API. For each filtered 3D shape, we randomly rotated the mesh and generated 10 data samples. For each data sample, we compute a  ground truth SDF volume using a CUDA-based program and render multi-view RGB and normal images using BlenderProc. In our experiments, the resolutions of the occupancy volume and sparse feature volume are 64 and 256, respectively. The resolution of the predicted and ground truth SDF volumes is 512. The model is trained with the Adam optimizer and a cosine learning rate scheduler. The loss weights  are set to 80, 2, 16, 2, 8, and 8, respectively.\nAll data preparation, including image rendering and SDF computation, is performed using an internal cluster. This process can be completed using 4000 CPU cores in roughly one week. The generated data takes up approximately 30TB. All model training tasks are conducted in public cloud clusters. Our main model is trained using 8 H100 GPUs for one week. All experiments listed in the paper can be completed in 15 days using 32 H100 GPUs (running multiple parallel experiments), excluding the preliminary exploration experiments.\nArchitecture Details:\nFor VoxelFormer, the UNet consists of four levels with resolutions of , ,  and . Each level includes a ResNet module, a projection-aware cross-attention module, and a downsampling module, with channel sizes of 64, 128, 256, and 512. We added 6 transformer layers at the bottleneck of the UNet, with each 3D voxel treated as a token, and token channels set to 512.\nFor SparseVoxelFormer, the sparse UNet consists of six levels with resolutions of , , , , , and . Each level includes a sparse ResNet module, a projection-aware cross-attention module, and a downsampling module, with channel sizes of 16, 32, 64, 128, 512, and 2,048. We added 16 transformer layers at the bottleneck of the UNet, with each 3D sparse voxel treated as a token, and token channels set to 1,024. The feature dimension of the output sparse feature volume (before the MLP) is 32.\nFor both of them, a skip connection is added to the UNet.\nEvaluation Metrics:\nTo account for the scale and pose ambiguity of the generated mesh from different baselines, we align the predicted mesh with the ground truth mesh prior to the evaluation metric calculation. This alignment process involves uniformly sampling rotations and scales for initialization and subsequently refining the alignment using the Iterative Closest Point (ICP) algorithm. We select the alignment that yields the highest inlier ratio. Both the ground truth and predicted meshes are then scaled to fit within a unit bounding box.\nFor 3D metrics, we sample 100,000 points on both the ground truth mesh and the predicted mesh and compute the F-score and Chamfer distance, setting the F-score threshold at 0.05. To evaluate texture quality, we compute the PSNR and LPIPS between images rendered from the reconstructed mesh and those of the ground truth. Following InstantMesh [85  ###reference_b85###], we sample 24 camera poses, encompassing a full 360-degree view around the object, and utilize BlenderProc for rendering RGB and normal images with a resolution of 320x320. Since we use the VGG model for LPIPS loss calculation during training, we employ the Alex model for LPIPS loss calculation during evaluation.\nAll results of MeshLRM, except those in Table 2  ###reference_###, were reproduced by the MeshLRM authors at Hillbot following the original settings as described in the paper. For the results in Table 2  ###reference_###, we trained the model using the same training data as our method on 8H100 GPUs for 48 hours. We maintained the same batch size as reported in the paper and proportionally scaled down the original training time for each stage of MeshLRM based on a total training time of 48 hours. This included 5.8 seconds per iteration for 20,000 iterations in the 256-resolution pre-training, 12 seconds per iteration for 4,000 iterations in the 512-resolution fine-tuning, and 4.7 seconds per iteration for 4,000 iterations in mesh refinement.\n###figure_8### Figure 8  ###reference_### shows qualitative results of One-2-3-45++ [31  ###reference_b31###] and CRM [77  ###reference_b77###] on single image to 3D and our method produces better results.\nWe introduce an efficient approach for training open-world sparse-view reconstruction models, which has the potential to significantly reduce energy consumption and carbon emissions, as baseline models typically require much more computing resources for training. Previously, the creation of 3D assets was reserved for specialized artists who spent hours or even days producing a single 3D model. Our proposed technique allows even novice individuals without specialized 3D modeling knowledge to create high-quality 3D assets in seconds. This democratization of 3D modeling has unleashed unprecedented creative potential and operational efficiency across various sectors.\nHowever, like other generative AI models, it also carries the risk of misuse, such as spreading misinformation and creating pornography models. Therefore, it is crucial to implement strict ethical guidelines to mitigate these risks."

+    "abstract": "Contrastive representation learning, which aims to learn the shared information between different views of unlabeled data by maximizing the mutual information between them, has shown its powerful competence in self-supervised learning for downstream tasks. However, recent works have demonstrated that more estimated mutual information does not guarantee better performance in different downstream tasks. Such works inspire us to conjecture that the learned representations not only maintain task-relevant information from unlabeled data but also carry task-irrelevant information which is superfluous for downstream tasks, thus leading to performance degeneration. In this paper we show that superfluous information does exist during the conventional contrastive learning framework, and further design a new objective, namely SuperInfo, to learn robust representations by a linear combination of both predictive and superfluous information. Besides, we notice that it is feasible to tune the coefficients of introduced losses to discard task-irrelevant information, while keeping partial non-shared task-relevant information according to our SuperInfo loss.We demonstrate that learning with our loss can often outperform the traditional contrastive learning approaches on image classification, object detection and instance segmentation tasks with significant improvements.",

+            "text": "Due to the huge cost in acquiring data notations, unsupervised learning has enjoyed its renaissance recently. Contrastive learning, whose goal is to learn powerful presentations for downstream tasks, has achieved promising success [56  ###reference_b56###, 11  ###reference_b11###, 36  ###reference_b36###, 49  ###reference_b49###, 21  ###reference_b21###, 19  ###reference_b19###, 17  ###reference_b17###, 41  ###reference_b41###]. Since there is no label information, contrastive learning usually estimates the mutual information between the learned representations of different views as its objective function such as SimCLR [5  ###reference_b5###], and takes the learned model as a features extractor for various downstream tasks, such as image classification, object detection and instance segmentation.\n###figure_1### To understand contrastive learning, we are often based on a multi-view assumption [45  ###reference_b45###, 58  ###reference_b58###]: either view of the unlabeled data is (approximately) sufficient for the label information so that we can pull similar data pairs close while pushing dissimilar pairs apart to obtain the shared information of different views. From this perspective, contrastive learning aims to maximize the lower bound of the mutual information between two augmentation views of the data so that the learned presentations are useful for downstream tasks. However, some researchers find counterintuitive examples. For instance, [53  ###reference_b53###, 50  ###reference_b50###] argue that maximizing the lower bound of the mutual information of the learned representations can not guarantee good performance for various downstream tasks, there are other factors which can not be ignored. [50  ###reference_b50###] did a series of experiments that reveals the relationship between the estimated mutual information between two augmentation views and downstream image classification performance (performance on CIFAR-10 [30  ###reference_b30###] and STL-10 [8  ###reference_b8###]), as shown in Figure 1  ###reference_###, with different data augmentations, the estimated mutual information between two augmentation views becomes larger and larger, however, the downstream classification performance does not vary with the changed estimated mutual information, but rather goes up at first and then goes down.\nBased on this phenomenon, we guess that the learned representations not only extract task-relevant information from the input data, but also carry task-irrelevant information which is superfluous for various downstream tasks, thus leading to performance degeneration. For the supervised learning, prior work [1  ###reference_b1###] straightforwardly discards task-irrelevant information from the input data by maximizing the mutual information between the learned representation and the label, while simultaneously minimizing the mutual information between the learned representation and the input data to make the learned representation more sufficient. While in the self-supervised framework, since there is no provided label information, each view plays a supervisory role for the other one, what we pay attention to is the shared information between different augmentation views. Through detailed analysis analogously to supervised learning,\nwe find that the mutual information between each augmentation view and its encoding is comprised of two components, task-relevant one and task-irrelevant one, further we can express each part with the notation of mutual information between different variables. As a consequence, we create a new objective function to remove task-irrelevant information while maximizing the mutual information between two different augmentation views, which can improve performance for various downstream tasks. Besides, we notice that we can tune the coefficients of introduced losses to discard task-irrelevant information, while simultaneously keeping partial non-shared task-relevant information according to different tasks. What\u2019s more, we draw a conclusion that the learned representations from our method can have a better performance than others on the downstream tasks when the multi-view redundancy is small by analyzing the Bayes Error Rate of different representations (See Section 3.3  ###reference_###).\nOverall, our contributions include:\nBased on prior works and supervised learning solutions, we excavate two independent parts, the task-relevant part and the task-irrelevant part, that make up the mutual information between each augmentation view and its encoding, and express each part with mutual information in different variables. Consequently, we design a new objective function to eliminate the task-irrelevant part.\nBy applying the theory of Bayes Error Rate, we prove that our learned presentations can perform better on the downstream tasks.\nWe verify the effectiveness of our method for contrastive representation learning framework by conducting image classification, object detection and instance segmentation experiments. What\u2019s more, we also run certain ablation experiments to analyze the role of the adding losses."

With the convenience of obtaining a mass of unlabeled data, different multi-views of unlabeled data are constructed to design the specific contrastive loss to obtain a powerful learned representation, such as multiple augmentations of one image [2  ###reference_b2###, 61  ###reference_b61###, 46  ###reference_b46###, 69  ###reference_b69###, 71  ###reference_b71###], different patches of one image [24  ###reference_b24###, 26  ###reference_b26###, 20  ###reference_b20###, 18  ###reference_b18###, 67  ###reference_b67###, 31  ###reference_b31###], text and its context[29  ###reference_b29###, 34  ###reference_b34###, 60  ###reference_b60###, 12  ###reference_b12###, 65  ###reference_b65###, 47  ###reference_b47###], different time slots of the same videos [70  ###reference_b70###, 43  ###reference_b43###, 35  ###reference_b35###, 48  ###reference_b48###, 4  ###reference_b4###, 59  ###reference_b59###], which pull similar data pairs close while push dissimilar pairs apart.\nThe intuition based on the contrastive idea is how to choose similar and dissimilar pairs, one feasible methodology is to maximize the shared information of different views (mutual information). Prior works [39  ###reference_b39###, 5  ###reference_b5###] have shown appealing performance in multiple downstream tasks according to this intuition. However, a few researchers draw some conclusions against intuition. The work by [53  ###reference_b53###] argues that maximizing the tighter bound of the mutual information between different variables may lead to worse representations, the success of these promising results should be also attributed to the parametrization of the employed mutual information estimators and the choice of encoder extractor architectures. Therefore, they design several experiments to verify their hypothesis.\nThe work [50  ###reference_b50###] demonstrates that the optimal view for contrastive representation learning is related to the given downstream tasks, meaning no need to maximize the mutual information of different views. Their InfoMin rule aims to figure out particular data augmentations to reduce the mutual information appropriately but does not find what component results in their hypothesis and does not give a general objective function, while our method considers standard augmentations (e.g., cropping, rotation, and colorization), theoretically analyzes the task-irrelevant information between different augmentations and designs a new objective function to eliminate this part. On the other hand, [52  ###reference_b52###] reveals that contrastive representation learning is able to extract task-relevant information and discard task-irrelevant information with a fixed gap and quantifies the amount of information that cannot be discarded.

A recent work [55  ###reference_b55###] refutes the conclusion given by [50  ###reference_b50###, 16  ###reference_b16###], argues that the minimal sufficient representation contains less task-relevant information than other sufficient representations and has a non-ignorable gap with the optimal representation, which may cause performance degradation for several downstream tasks, suggesting increasing the mutual information between the input data and its encoding in the objective function. However, this adjustment maybe can bring more useful information but is also likely to introduce more noise for different downstream tasks.\n###figure_2###"

Since the label y can be obtained in supervised representation learning, the training metric is usually built up with the representation z and the label y. What\u2019s more, to make the representation more general and more robust, [1  ###reference_b1###] applies the Information Bottleneck theory [51  ###reference_b51###] to establish a new objective function, the purpose is to make the representation z more sufficient for the label y. We discuss the concept of sufficiency of supervised representation learning by the following definition.\nSufficiency in supervised representation learning: A representation z of the input data x is sufficient for the label y if and only if  (Where  represents the mutual information between variables).\nAccording to Definition 1, we know that the learned sufficient representation z contains all the information related to the label y after the model properly encodes the original input data x, and it may be well-performed for different evaluation tasks. Since the input data x usually has high-level semantic information compared to the label y, there certainly exists some information in x which is irrelevant for y, we can regard these as task-irrelevant (superfluous) information. By decomposing  into two terms using the chain rule of mutual information (proof in Appendix B.1  ###reference_###).\nThe conditional mutual information  expresses the mutual information between x and z, which is task-irrelevant for y, so this is superfluous. It is better to make this term as small as possible. While the other term  represents how much task-relevant information contained in the representation, which we want to maximize. Obviously reducing the amount of superfluous information can be done directly in supervised learning. As a consequence, [1  ###reference_b1###] combines two terms  and  to make the model learn a more sufficient representation.\nSince there is label information in the supervised setting, we can easily analyze superfluous information and useful information. As for self-supervised representation learning, there are only different augmentation views from the unlabeled data, the only useful information to be leveraged is the shared information between different views. Consider  and  as two different views of data x and let y be its label. Similarly  and  become representations of two different views  and  after processed by the network. Therefore, the main objective is to obtain as much shared information of two views as possible, usually maximizing the mutual information of two representations  and  () is what we pay attention to. Nevertheless, like supervised representation learning, there must be some task-irrelevant (superfluous) information contained in the learned representation. Consequently we want to extract task-relevant and discard task-irrelevant information simultaneously. To formalize this we define sufficiency for self-supervised representation learning.\nSufficiency in self-supervised representation learning: A representation  is sufficient of  for  if and only if .\nIntuitively,  is sufficient if the amount of information in  about  is unchanged by the encoding procedure. Symmetrically,  is sufficient of  for  if and only if .\n(Minimal sufficiency in self-supervised representation Learning) The sufficient representation  of  is minimal if and only if ,  that is sufficient.\nFrom the above definition, we can see that a sufficient representation contains exactly all the shared information between  and . Therefore, maintaining the representations sufficient and discarding superfluous information between two views and their representations simultaneously is particularly significant. We can show the following equation by factorizing the mutual information between  and  into two terms, (similarly for  and ):\nSimilar to Equation 1  ###reference_###,  can be decomposed into predictive information component and superfluous information component. Since  expresses the information between one representation and the other view, it makes a contribution to the task-relevant information between two views. On the other hand,  means the information contained between  and  while the view  has been observed, as shown in Figure 2  ###reference_###. The larger this term, the more non-shared information between two views, so reducing (or minimizing)  can make the learned representation more sufficient. The proof of Equation 2  ###reference_### can be found in appendix B.2  ###reference_###."

We use the similar set of image augmentations as in SimCLR [5  ###reference_b5###]. For CIFAR10 [30  ###reference_b30###] and STL-10 [8  ###reference_b8###], random cropping, flip and random color distortion are applied, and for ImageNet [10  ###reference_b10###], a random patch of the image is selected and resized to 224 \u00d7 224 with a random horizontal flip, followed by a color distortion, consisting of a random sequence of brightness, contrast, saturation, hue adjustments, and an optional grayscale conversion.

With this evaluation, we know whether SuperInfo\u2019s representation generalizes beyond classification tasks.\nPASCAL VOC object detection [14  ###reference_b14###]. The model is Faster R-CNN [42  ###reference_b42###] with a backbone of R50-C4 [22  ###reference_b22###] with BN tuned.

Therefore, we conduct the classification experiments (including downstream classification) of only adding the terms,  () or only adding another terms,  () to see whether there are apparent different performances with the original SuperInfo (, ). Following the same setting in section 4.1  ###reference_###, we just train the model on CIFAR10 and STL-10 by changing  and apply linear evaluation protocol to other classification datasets. We report the results in Table 3  ###reference_###. It can be clearly seen that the accuracy on the source dataset (CIFAR10 and STL-10) can achieve the similar level compared to original SuperInfo while only adding  and  since this change can discard superfluous information, but the downstream classification performance gets worse to a certain extent because several non-shared task-relevant information does not keep. On the other hand, only adding  and  is better than original SuperInfo on the source dataset (CIFAR10 and STL-10), but can not beat original SuperInfo on transfer datasets, which means only introducing non-shared task-relevant information may bring certain noise, leading to the phenomenon of over-fitting on transfer datasets.\n###figure_7### ###figure_8### Training with more epochs. We train all models for 200 epochs during all above experiments.

The results are listed in Figure 4  ###reference_###. According to the above figure, we find that the downstream classification accuracy does not become better with more training epochs, even decreases in the middle period since the learned representations in contrastive representation learning are able to get more close to the minimal sufficient representation which only contains the shared information between different views with more training epochs and the minimal sufficient representation may have the risk of over-fitting on the transfer datasets. This phenomenon is consistent with the conclusion in [55  ###reference_b55###]. What\u2019s more, SuperInfo does bring significant improvements compared to vanilla SimCLR on the transfer datasets under every training epochs. On the other hand, we change the coefficients (, ) compared to vanilla SuperInfo, training the model on CIFAR10 and evaluating the model on other transfer datasets. The results are reported in Figure 5  ###reference_###. As shown in 5  ###reference_###(b), the classification accuracy increases stably with the training epochs, however, the performance on the source dataset (CIFAR10) does not keep the pace with it. This phenomenon shows there really exists a trade-off of the performance on source dataset and on other transfer datasets with respect to the coefficients."

[23  ###reference_b23###]\nwe give efficiently computable semidefinite programming bounds on the size of quantum codes [Result C  ###reference_A3###, Section 8  ###reference_###].\nSimilar to the classical case, these scale as , where  is the block length,\nand build on the block-diagonalization of the Terwilliger algebra\nof the non-binary Hamming scheme.\nWith this, we give an an alternative proof that there is no  quantum code 111\nNote that the original proof in Ref. [30  ###reference_b30###]\ndoes not make use of mathematical optimization., as well as prove the non-existence of quantum codes with parameters  and  [Section 9  ###reference_###].\nThus the method is strictly stronger than the\n\u201cenhanced\u201d quantum linear programming bounds\nthat include the shadow bounds by Rains [58  ###reference_b58###, 57  ###reference_b57###],\nwhich do not recover this result.\nOur second main result is that these\nbounds are part of a complete semidefinite programming (SDP)\nhierarchy [Result A  ###reference_A1###, Section 4  ###reference_###].\nIf a code with given parameters  does not exist, then\nsome level of the hierarchy will be infeasible.\nThis hierarchy is based on the state polynomial optimization framework,\nwhich provides a sequence of outer approximations\nto the set of non-linear quantum correlations.\nApproximating  one can also recover  through the quantum MacWilliams identity,\nand impose the constraints  for  based on the Knill-Laflamme conditions for quantum error correction.\nWhile this machinery is formally dimension-free,\na characterization of quasi-Clifford algebras by Gastineau-Hills [21  ###reference_b21###]\npulls this result back to -qubit systems.\nOverall, our approach is applicable to both stabilizer and non-stabilizer codes.\nIt is based on moment matrices and thus offers high flexibility on the constraints\nto be included,\nso that small relaxations can be constructed.\nLastly, because our formalism is dimension-free,\nit can also target scenarios where the Hilbert space is unknown."

The Lagrangian is then defined as\nso the dual objective function is\nThe dual problem can then be expressed as\nBy eliminiating the slack variable  and redefining  with , one obtains\nWe use this to write the dual program of\nthe feasibility version of the symmetry reduced quantum Lov\u00e1sz number for self-dual codes,\nThe dual program of Eq. (9.1  ###reference_9###) is\nwhere  with \nare real square matrices of size .\nFor the derivation of the dual program,\nwe slightly modify the conditions from Eq. (9.1  ###reference_9###) when  to obtain the equivalent formulation:\nwhere  is given by Eq. (6.3  ###reference_7###).\nNote that the condition  if  is equivalent to the pure code condition from Eq. (141  ###reference_1###).\nThis can be seen from that fact that when , it simplifies to  if .\nBut  implies that  for any :\nConsider  with .\nThen . The constraint  implies that  for any  with ,  and .\nThis is due to the fact that the  minor of  involving  and  must be positive-semidefinite, and thus if  then also .\nConsider now the Lagrangian of SDP (A.1  ###reference_35###).\nAssociate with each equality constraint a dual variable\n\nand with each semidefinite constraint a dual semidefinite variable .\nEq. (A.1  ###reference_35###) is a feasibility problem and so the objective function equals zero.\nThen\nFor the last term, we have developed the trace of each block of the direct sum in Eq. (A.1  ###reference_35###) multiplied by the dual variable  to obtain\nwhere we have used the fact that  is symmetric. Define the following set corresponding\nto the sums appearing in\nEq. (160  ###reference_0###),\nEq. (160  ###reference_0###) then simplifies to\n.\nNote that  is equivalently defined by\nEq. (160  ###reference_0###) is then simplify to . Note that the set  is equivalently defined by\nwith  given by Eq. (76  ###reference_###).\nTo see this note that the first two inequalities in Eq. (A.1  ###reference_40###) combine to\n from which  follows.\nThen the remaining condition  is captured by .\nTherefore,  can also be written as\nDefine now \nwhich is the inner term of the last expression in Eq. (A.1  ###reference_38###). Since  and  are symmetric functions with respect to  and , then also  is symmetric.\nFactorize the primal variables in the Lagrangian of Eq. (A.1  ###reference_38###),\nHere we used that , , and , to decompose\nThe dual objective function is then\nOtherwise, it tends to .\nNote that conditions (2) and (5) appearing in Eq. (167  ###reference_7###),\ndo not constrain the objective function.\nThis can be seen from the fact that the variables  do not appear in the objective function and neither in the rest of constraints. Thus, they act as slack variables which can always take values so that the above two conditions are satisfied.\nAll dual variables can be expressed in terms of the semidefinite dual constraints  and \nusing the remaining constraints in Eq. (167  ###reference_7###):\nuse condition (1) to eliminate  and condition (4) to eliminate .\nThe dual problem can then be expressed as Eq. (25  ###reference_30###).\nIn particular, the objective function reads ,\nand the remaining constraints (3) and (6) read:\nThe dual program then reads\nFinally, one can check from Eq. (77  ###reference_###) that .\nThus, by mapping the variable , the constraints in the SDP above simplify to Eq. (25  ###reference_30###) since  factorizes.\nThis ends the proof.\n\u220e\nGiven the relaxation of symmetry reduced SDP in Eq. (9.2  ###reference_10###), the dual program reads\nHere the dual variables are real matrices  of size  with  and\n with .\nFor convenience, we perform the following variations to the SDP (9.2  ###reference_10###):\nSubstitute  for  since they are equivalent\n(see Proposition 19  ###reference_orem19### ff.).\nConsider  independent from the remaining conditions in (iii) from Proposition 18  ###reference_orem18###.\nAs result the SDP from Eq. (9.2  ###reference_10###) is now written as\nwhere  is given by Eq. (6.3  ###reference_7###). In all the development, we will impose that .\nSimilarly to the previous section, we now construct the Lagrangian. Associate with each equality constraint a dual variable  and with each semidefinite constraint a dual semidefinite variable  and the objective function equals to . Then\nAs shown in the development from Eq. (160  ###reference_0###) to Eq. (163  ###reference_3###), the last term arises as the the trace of the product of the primal and dual semidefinite variables.\nBefore proceeding with the Lagrangian, we simplify the last term in the second line\nof Eq. (A.2  ###reference_66###) coming from the structure constraint\nby reorganizing its elements as\nwhere\nFrom the definition of  follows a first constraint:\nfor  with  even and ,\nThis can be seen by taking Eq. (175  ###reference_5###) and developing the left hand side of Eq. (176  ###reference_6###) as\nNote that the right and left hand side of the above equation sum over the same elements and thus, they are equal.\nDefine also  and .\nWe then factorize the primal variables so that\nAs done in Eq. (165  ###reference_5###), we have decomposed\nBy Eq. (A.2  ###reference_72###), the dual objective function is then\nOtherwise, it tends to . Similarly to Eq. (A.1  ###reference_44###), condition (5) above,\ndoes not constrain the objective function. Again,  acts as a slack variable\nwhich can always take values such that Eq. (181  ###reference_1###) is satisfied.\nAll dual variables can be expressed in terms of  using the remaining of constraints in Eq. (180  ###reference_0###). First, use condition (1) to derive the objective function of the dual which reads . Then apply condition (4) to (2) and (3) to obtain respectively,\nFinally, we use the property of  described in Eq. (176  ###reference_6###) together with condition (6) and thus,\nThe dual program then reads as\nFinally, one can check from Eq. (77  ###reference_###) that  if  is even and  is a permutation of . In particular, .\nThus, by mapping the variable , the constraints in the SDP simplify to Eq. (26  ###reference_52###) since  factorizes.\nThis ends the proof.\n\u220e"

Utilizing OSS code can greatly accelerate software development, reduce redundancy, and enhance reliability. Python, a widely adopted programming language, is renowned for its extensive and diverse third-party package ecosystem. However, a significant number of OSS packages within the Python ecosystem are in poor maintenance, leading to potential risks in functionality and security.\nConsequently, it is essential to establish a deprecation mechanism to assist package developers and users in managing packages effectively.",

+            "text": "Open-source software (OSS) has become a ubiquitous and influential presence in the software industry, resulting in considerable economic ramifications [1  ###reference_b1###, 2  ###reference_b2###, 3  ###reference_b3###]. Notably, a recent survey [4  ###reference_b4###] uncovered that 89% of UK companies utilize OSS.\nHowever, OSS projects are usually developed and maintained by volunteers [1  ###reference_b1###, 5  ###reference_b5###], who may discontinue their involvement due to time constraints, lack of interest, or personnel turnover [6  ###reference_b6###, 7  ###reference_b7###], resulting in inadequate or no maintenance for the software. Adopting poorly maintained OSS projects poses significant risks and potential losses to the software industry.\nSynopsys\u2019 recent report on open-source security and risk analysis (OSSRA) [8  ###reference_b8###] revealed that 89% of the analyzed codebases contained outdated open-source components that were over four years old, and 84% of them had at least one known open-source vulnerability.\nTo mitigate the challenges resulting from outdated code and its associated issues, such as the propagation of vulnerability, researchers have recommended the implementation of a deprecation mechanism [9  ###reference_b9###].\nThe deprecation mechanism allows developers to officially declare the software as obsolete and discourage users from using it [10  ###reference_b10###, 11  ###reference_b11###].\nVarious programming language ecosystems have embraced the concept of deprecation, including languages such as JavaScript and Rust. For instance, in JavaScript, Node Package Manager (NPM) provides a deprecation mechanism that allows developers to mark packages as deprecated [12  ###reference_b12###], thereby warning users about their outdated nature and suggesting alternative solutions.\nSurprisingly, despite being one of the most popular programming languages [13  ###reference_b13###] with over 400k third-party packages, Python lacks a formal or widely recognized package-level deprecation mechanism in its ecosystem, hindering package developers from releasing explicit deprecation announcements.\nIn this paper, deprecated packages in the Python ecosystem are identified as those that include an explicit deprecation declaration, indicating that they will no longer receive maintenance.\nWe consider inactive packages as those that have not received any updates for a long time, surpassing their regular maintenance schedule.\nIt is important to note that not all inactive packages are necessarily abandoned. Some may be considered complete in functionality, thus slowing down their maintenance [6  ###reference_b6###].\nThis intricate nature of inactive packages poses challenges for users in determining the package\u2019s status when no deprecation announcement is available, subsequently exposing them to potential risks and issues [3  ###reference_b3###].\nTo mitigate these negative impacts, there is a strong demand to develop a deprecation mechanism in the Python ecosystem that enables developers to deliver explicit and effective information.\nWhile the Python ecosystem does not have an official package-level deprecation mechanism, developers have implemented their own approaches to announce deprecation in recent years. One common practice is to include deprecation information in the README file of the package repository. Furthermore, developers often offer alternative package options as part of the deprecation process.\nHowever, there is a lack of awareness regarding the existing deprecation patterns throughout the entire Python ecosystem.\nThe prevalence of these deprecation patterns is also unknown.\nIn addition, it is important to investigate whether these existing deprecation patterns meet the requirements of both package developers and users.\nTo address this gap, we conducted a mixed-method empirical study to examine the early efforts made in deprecating Python packages and gather feedback from package developers and users regarding the current deprecation patterns.\nConcretely, we address the following research questions:\nRQ1: How is package-level deprecation currently made, received, and handled?\nWe successfully identified 9,173 deprecated packages that announce their deprecation through various methods, such as GitHub archiving, homepage notifications, issue trackers (e.g., GitHub issues) when users inquire, and warnings during installation.\nHowever, these deprecated packages only account for 1% of the inactive packages, and for the remaining ones, we are unable to determine their status.\nAmong the identified deprecated announcements, only 8.7% have provided alternative solutions.\nEven after six months since the deprecation was announced, two-thirds of the users remain unaware of the deprecation.\nThis is primarily due to infrequent checks on the maintenance status of the dependencies of their packages.\nNevertheless, over two-thirds of the users are willing to take action regarding the dependency when directly or transitively affected by vulnerabilities. This includes removing the deprecation, finding alternative solutions, and creating a new fork.\nRQ2: Can deprecation announcements mitigate the negative impacts of inactive maintenance?\nWe verified that having a deprecation announcement can reduce the unresolved issues on GitHub and the adoption of downstream packages, indicating the alleviation of risks.\nAdditionally, most users agree that having a deprecation announcement helps reduce the decision efforts when deciding whether to adopt or remove an inactive package.\nRQ3: Why do inactive packages rarely release a deprecation announcement?\nThis is primarily attributed to a lack of time and resources, uncertainty about how to provide an announcement and make future plans.\nMoreover, it is worth noting that developers often have limited awareness of the usage of their packages, which further complicates their decision-making process regarding future plans and whether to announce a deprecation.\nRQ4: What are the expectations of package developers and users regarding the future deprecation pattern?\nWhile the majority of the package developers expressed their willingness for the package manager to automatically handle deprecation tasks upon their request, announcing the deprecation manually is still preferred by many developers.\nAs for package users, the majority of them express their need to receive deprecation notifications through warnings during installation or via email, which should also include information about alternative solutions.\nThey also want additional support, such as\nmigration guidelines, and guidance on taking over the projects.\nIn summary, we made the following contributions:\nWe performed an empirical study to understand the status quo and challenges of package-level deprecation in the Python ecosystem. This study can serve as a cornerstone for establishing a deprecation mechanism for Python.\nWe discussed the practical implications of managing package-level deprecation for the community.\nWe collected and released a large-scale dataset at https://doi.org/10.5281/zenodo.13335360  ###reference_###, consisting of 106,323 packages.\nThe dataset can be used to facilitate future research."

Consequently, the vulnerability remains a persistent risk for years [16  ###reference_b16###, 17  ###reference_b17###].\nIn general, developers utilize a deprecation mechanism to discourage consumers from adopting obsolete functionalities.\nA typical deprecation mechanism follows three steps. The first step is declaration, where the deprecation status is explicitly stated. The second step is to deliver the deprecation message to the consumers. Lastly, index update prevents consumers from searching for deprecated packages or releases.\nDepending on the objects or functionalities to be deprecated, different levels of deprecation mechanisms exist.\nTraditionally, developers can leave warnings with an API-level deprecation mechanism to discourage consumers from adopting an abandoned object or functionality [18  ###reference_b18###, 19  ###reference_b19###].\nWith the evolution of software, numerous historical releases remain in the ecosystem and are available for consumers to choose from. If specific versions of package releases are found to be buggy or even vulnerable, developers may consider using a release-level deprecation mechanism to deprecate those specific versions [20  ###reference_b20###].\nHowever, developers who adopt these practices do not necessarily intend to give up the maintenance of entire packages.\n###figure_1### In cases where developers decide to give up maintaining packages and discourage consumers from further using the package, a package-level deprecation mechanism can be employed to deprecate the unmaintained packages and deliver the deprecation declaration.\nVarious programming languages already have existing package-level deprecation mechanisms.\nFor instance, in npm for Javascript, developers can implement a package-level deprecation mechanism to leave a message for new consumers attempting to install a deprecated package.\nHowever, despite discussions regarding a package-level deprecation mechanism for the Python ecosystem for years [21  ###reference_b21###, 22  ###reference_b22###], no existing package-level deprecation mechanism currently exists within the Python ecosystem.\nThe absence of the deprecation mechanism leaves package users unaware of the risks associated with adopting the package, thereby increasing the decision effort required.\nOne motivating example is Python-Kafka, which has no release in the last 1.5 years.\nUsers are concerned about the compatibility risks of using the package and have already encountered bugs. As a result, they have inquired about whether the package has been deprecated via submitting a GitHub issue. However, the reply remains ambiguous, leaving users in a state of uncertainty [23  ###reference_b23###].\nTo facilitate the establishment of a deprecation mechanism in the Python ecosystem, we conducted a mixed-method empirical study that included data analytics and two user studies."

This step was taken to manage risks associated with the upstream dependencies. For example, these packages may become inactive as a result of the same incident occurring in the upstream dependency.\nRather than including all its brothers in the subset, we only selected 5 packages with the closest number of stars in the corresponding GitHub repository.\nMoreover, we took standard precautions while estimating the models in the following manner.\nWe used log-transforming variables to mitigate heteroscedasticity with skewed distributions [38  ###reference_b38###], except for the gain of downstream dependencies, which includes negative values.\nTo assess multicollinearity, we utilized the Variance Influence Factor (VIF) from the car package in R [39  ###reference_b39###].\nThe results are presented in Table IV  ###reference_###."

This is understandable since GitHub is a powerful tool for developers, while PyPI serves as an archive.

Considering the low proportion of deprecation announcements and the lack of information, it is recommended to develop a deprecation mechanism that assists developers in effortlessly providing detailed deprecation announcements and effectively communicates the message to users.\nMoreover, many developers have already announced or prefer to announce deprecation on GitHub, as it is a developer-centric tool and the platform where developers primarily focus their attention.\nTherefore, it is also recommended for the future deprecation mechanism to establish a connection with code hosting platforms such as GitHub, which enables comprehensive monitoring of maintenance status and a more comprehensive collection of deprecation announcements.\nWhen no explicit deprecation announcement is available, having finer-grained categories of statuses that indicate different levels of risks may be beneficial.\nFigure 5  ###reference_###(a) demonstrates that developers may choose not to provide a deprecation announcement for various reasons even if their packages have been without maintenance for a significant period and some are unlikely to be revived in the future.\nWhile some packages may still function well, others may encounter compatibility or security issues.\nThese diverse statuses indicate varying levels of usability and security risks, suggesting that deprecation status can extend beyond binary options to include finer-grained categories.\nIf the risks associated with packages in different statuses can be evaluated and separated using defined boundaries, along with explicit descriptions, it would also assist package users in determining whether to adopt or remove a package even in the absence of explicit messages from developers.\nWe recommend that further attention be given to this research topic.\nA more user-friendly practice is needed for users who want to take over the package.\nAlthough most users express a desire for alternative solutions to be included in the deprecation announcements, the findings in Section IV-A1  ###reference_.SSS1### reveal that only a low proportion of deprecation announcements actually provide such alternative solutions.\nWhile previous works have focused on recommending alternative solutions at the package level and API level [44  ###reference_b44###, 45  ###reference_b45###], one concern is the lack of potential alternative solutions.\nIn such situations, users can only maintain the dependencies themselves if they want to keep risks under control.\nInstead of creating a new forked version, inheriting the deprecated package can retain users, saving them the effort of finding an alternative solution. Additionally, developers will not need to find new users since existing users can act as good testers of the package, reducing maintenance efforts.\nHowever, a user who has decided to maintain the dependency himself mentioned that the requirements set by PEP 541 [46  ###reference_b46###], which is the official practice for inheriting the package, are too high.\nFurthermore, even if all the conditions are met, the review process by the Python Software Foundation official member may take a long time due to the volunteer/staffing shortage [47  ###reference_b47###].\nWhile PEP 541 can ensure security through its conservative strategies, it is suggested to have a supplementary mechanism with looser conditions to facilitate the takeover of packages. This mechanism should also inform users about the associated risks.\nExploring better solutions for backward compatibility in the Python ecosystem is necessary.\nDespite the developers having completed the development of all the planned features, keeping the packages up-to-date remains a non-trivial task.\nSome developers, as expressed in our surveys, have indicated that maintaining the package is labor-intensive and sometimes annoying.\nIt often requires more time than the initial development process itself.\nIn general, to prevent functionality and security issues, packages need to update their dependencies with patches. However, the frequent occurrence of breaking changes in these dependencies further complicates the maintenance process, leading to developer frustration.\nFrom the perspective of upstream dependencies, backporting patches to older versions that have no breaking changes is also a labor-intensive task, especially considering the existence of multiple previous version tracks.\nTherefore, it is recommended to explore the possibility of automatically backporting patches without causing breaking changes. By improving the backward compatibility of the Python ecosystem, maintenance tasks could become more manageable and potentially even automated."

One challenge involved collecting dependency information for the entire Python ecosystem, which can be difficult. Various methods for obtaining dependency information have been adopted in many papers. A common data source used by researchers is the data dump from Libraries.io [55  ###reference_b55###]. However, this data dump suffers from certain weaknesses. Firstly, it is outdated, with its last dump released on January 12, 2020, lacking information on packages and releases in recent years. Additionally, it may contain missing dependencies, a common and easily detectable issue.\nResearchers can also access dependency information by utilizing the API provided by PyPI [56  ###reference_b56###]. However, this source also suffers from incompleteness, similar to Libraries.io. To overcome these limitations, we leveraged the code provided by Valiev et al. [3  ###reference_b3###] to extract dependency information from distribution files on PyPI. This approach surpasses the previous methods in terms of timeliness and completeness.\nAdditionally, we encountered rare instances of missing distribution files on PyPI and missing issues on GitHub due to deletion. However, such occurrences are not substantial enough to affect the validity of our results.\nWhen identifying deprecated packages from inactive ones, we adopt a keyword search strategy to identify deprecation announcements from related README and issues.\nHowever, this strategy can miss some packages that did have a deprecation announcement without those keywords and incorrectly consider these packages as inactive ones.\nTo validate this risk, we sampled 383 inactive packages without keywords. The sample size was determined using the sample size calculator, following the same procedure described in Section III-E  ###reference_###. Subsequently, two of our authors checked for any deprecation announcements that might have been missed by our previous identification method. We found that there are 6 packages where this was the case, indicating that the accuracy of our previous method is 98.4% with a 95% confidence interval.\nThe two surveys are also influenced by social desirability bias [57  ###reference_b57###] and self-selection bias [58  ###reference_b58###]. To alleviate these biases, we tried to collect more responses by sending invitation emails to people who may be interested in the study.

+    "abstract": "Emotion recognition from electroencephalogram (EEG) signals is a thriving field, particularly in neuroscience and Human-Computer Interaction (HCI). This study aims to understand and improve the predictive accuracy of emotional state classification through metrics such as valence, arousal, dominance, and likeness by applying a Long Short-Term Memory (LSTM) network to analyze EEG signals. Using a popular dataset of multi-channel EEG recordings known as DEAP, we look towards leveraging LSTM networks\u2019 properties to handle temporal dependencies within EEG signal data. This allows for a more comprehensive understanding and classification of emotional parameter states. We obtain accuracies of 89.89%, 90.33%, 90.70%, and 90.54% for arousal, valence, dominance, and likeness, respectively, demonstrating significant improvements in emotion recognition model capabilities. This paper elucidates the methodology and architectural specifics of our LSTM model and provides a benchmark analysis with existing papers.",

The unique ability of EEG signals to provide a very descriptive temporal view of brain activity makes it an indispensable tool for understanding complex human emotional states. This capability is especially critical in contexts where the traditional means of emotion assessment are impractical or unfeasible.\nIn recent years, there has been a necessity for understanding and quantifying emotional responses, which has led to advancements in academic research. This has opened new doors for consumer research, mental health, and assistive technologies. The prospect of its ability to assist individuals who would otherwise not be able to express emotions through traditional ways, such as facial expressions, body language, and speech, makes this one of the exciting fields for EEG-based recognition of emotions. These individuals would include, but not be limited to, people with communication disabilities, for example, aphasia; other conditions encompass Autism Spectrum Disorder (ASD) [7  ###reference_b7###], among others; and those who have severe physical disabilities from traumatic brain injuries or other progressive diseases, such as Amyotrophic Lateral Sclerosis (ALS) [3  ###reference_b3###].\nStatistically, it has been estimated that in the United States alone, approximately 6.6 million people have been diagnosed with some communication disorder [14  ###reference_b14###]. From such figures in the global context, it can be estimated that up to 1% of the world population has some form of autism spectrum disorder. These people\u2019s emotional expression and interpretation remain very conventional, usually exhibiting a failing nature. Such failures, thus, stimulate the need to develop standalone technologies that will independently interpret emotional states from physiological data.\nEEG-based technologies offer a non-invasive, more direct window into the neural underpinnings of emotion. Since it measures electrical activity, the EEG provides a dynamic mapping of activity in the brain, potentially associated with states of emotion without the need for verbal reports or precise physical gestures. This approach is particularly suitable for those whose neurological conditions impair their effective communication.\nThe rise of Long Short-Term Memory (LSTM), a variation of Recurrent Neural Networks (RNNs), has revolutionized this field with its ability to analyze and classify EEG data at unprecedented success rates. LSTMs, in particular, are very strong at modelling the time-dependent features that underlie EEG data. They can capture such underlying patterns temporally, which indicate different emotional states. This advanced machine learning method elevates the prediction performance for emotion classification systems from EEG. It opens an avenue to building real-time responsive systems that can adapt to the emotional feedback of users in different applications.\nFurthermore, emotion recognition by EEG is possible in healthcare and societal applications. In healthcare, technology could offer better patient care, for instance, since it can interpret pain, discomfort, or emotional distress that patients might be unable to express. One case for this was gauging emotional states in palliative care cancer patients [17  ###reference_b17###]. In special education, EEG in non-verbal students could help teachers and caregivers explore the thoughts and emotional states of the students. This could enable tailor-made educational approaches that are more in sync with the mindset of the students [18  ###reference_b18###].\nThis study aims to develop more accurate and specific tools for cognitive emotion recognition, particularly for detecting and interpreting emotional states in persons unable to express themselves by traditional means."

Also, significant correlations were found between the participant ratings and EEG frequencies. The single-trial classification was performed for arousal, valence, and liking scales using features extracted from the EEG, peripheral, and MCA modalities. The results were shown to be significantly better than random classification.\n\n\nAlhagry et al. [2  ###reference_b2###] proposed LSTM networks for emotion recognition from raw EEG signals. Their study demonstrates that the LSTM model achieves high average accuracies across three emotional dimensions and outperforms traditional emotion recognition techniques, marking a significant advancement in the field.\n\n\nNie et al. [16  ###reference_b16###] explore the relationship between EEG signals and emotional responses while watching movies, focusing on classifying emotions into positive and negative categories. Their application of a Support Vector Machine (SVM) on processed EEG features resulted in an impressive average testing accuracy of 87.53%, underscoring the potential of EEG-based methods in practical multimedia applications.\n\n\nLi et al. [11  ###reference_b11###] provide a comprehensive overview of EEG-based emotion recognition, exploring the integration of psychological theories with physiological measurements. They review various machine learning techniques, from conventional models to advanced computational methods, highlighting key advancements and challenges in the field.\n\n\nZheng et al. [21  ###reference_b21###] develop an innovative approach by integrating deep belief networks with hidden Markov models for EEG-based emotion classification. Their findings indicate that this combined DBN-HMM model achieves higher accuracy than traditional classifiers, highlighting its effectiveness in leveraging spatial and temporal EEG data dimensions.\n\n\nBhagwat et al. [6  ###reference_b6###] proposed a novel approach for classifying four primary emotions: happy, angry, crying, and sad, which can be visualized as four quadrants. They used Wavelet Transforms (WT) to extract features from raw EEG signals and employed a Hidden Markov Model (HMM) to classify emotions.\n\n\nLin et al. [13  ###reference_b13###] utilize EEG data and machine learning to enhance emotional state predictions during music listening. Using an SVM, their approach achieves an average classification accuracy of 82.29% for emotions such as joy, anger, sadness, and pleasure.\n\n\nNaser and Saha [15  ###reference_b15###] applied advanced signal processing techniques to improve feature extraction for emotion classification from EEG signals. Their study utilizes dual-tree complex wavelet packet transform (DT-CWPT) and statistical methods like QR factorization and singular value decomposition (SVD) to select discriminative features effectively. The enhanced feature set is then classified using an SVM, demonstrating notable improvements in classification accuracy.\n\n\nLi et al. [12  ###reference_b12###] found that while it is feasible to work with single-channel EEG data, it is much more effective to combine multiple channels of EEG features into a single feature vector. They also found that the beta and gamma frequency bands are more related to emotional processing than the other bands.\n\n\nThe exploration of adaptive emotion detection using EEG and the Valence-Arousal-Dominance model by Gannouni et al. [8  ###reference_b8###] advances the field by adapting computational models to individual brain activity variations. Their method employs an adaptive selection of electrodes, significantly enhancing emotion detection accuracy. Utilizing machine learning algorithms, the study demonstrates a 5% and 2% increase in accuracy for valence, arousal, and dominance dimensions, respectively, compared to fixed-electrode approaches.\n\n\nAlvarez-Jim\u00e9nez et al. [22  ###reference_b22###] enhance EEG-based emotion recognition by integrating diverse feature sets from multiple domains. Their use of various classifiers, including Artificial Neural Networks, achieves a high accuracy of 96%, demonstrating the effectiveness of hybrid features in improving model robustness.\n\n\nAtkinson-Abutridy et al. [5  ###reference_b5###] proposed a feature-based emotion recognition model combining statistical-based feature selection methods with SVM classifiers, focusing on Valence/Arousal dimensions for classification. This combined approach outperformed other recognition methods.\n\n\nYoon and Chung [20  ###reference_b20###] detailed a probabilistic classifier based on Bayes\u2019 theorem and a supervised learning approach using a perceptron convergence algorithm, offering a methodologically distinct perspective on emotion classification from EEG signals."

Valence measures the \u2019how good or bad\u2019 of the mood, arousal measures the activation level, and dominance measures how much control one might feel they have over their emotional state.\nResearchers have adopted this model in examining features of EEG that indicate the functioning of different areas in the brain toward emotional stimuli. Research has shown that the positive effect increases alpha band activity in the frontal regions. In contrast, the negative one tends to decrease it, and high arousal corresponds to beta activity.\n\n\nThe usage of recent advanced classification techniques, even with segmenting EEG data into minor epochs, has increased the accuracy of emotional assessments. Such improvements enhance the accuracy by around 5% for valence and arousal and 2% for dominance, respectively, hence depicting the effectiveness of the VAD model in the subtle multi-dimensionality characterization of human emotions [8  ###reference_b8###].

Traditional statistical approaches to data analysis require manual choice of features, and at most, they can only model the linear effects. This is essential in EEG data, where emotional states are not explicitly encoded but latent constructs reflected in slight signal variations. Deep learning models enable learning such patterns directly from raw data, optimizing feature extraction, selection, and classification tasks in a joint form. This shows that robust and accurate analysis is developed in high dimensionality and noise levels that are usually related to EEG recordings."

This problem, in turn, makes it very hard for them to be trained on sequential data where long-term contextual information is essential. LSTMs solve this problem due to the exceptional structure of their gates, which allows them to regulate the flow of information in a way that enables them to remember or forget information for long periods."

We utilized specific EEG channels and frequency bands relevant to emotional processing. The chosen channels included a subset correlating with emotional states, such as frontal and temporal regions. Frequency bands were segmented into five distinct ranges: theta (4-8 Hz), alpha (8-12 Hz), low beta (12-16 Hz), high beta (16-30 Hz), and gamma (30-45 Hz), which are traditionally associated with different aspects of cognitive processing and emotional regulation (Refer to Table 2 and Fig. 3 [4  ###reference_b4###]). Each of these bands aids in extracting vital information from input EEG data, which has been proven to support sentiment analysis [4  ###reference_b4###]. The Fast Fourier Transform (FFT) process was applied to a select 14 channels of the recorded 32 channels, chosen to fit Emotiv Epoc, with a window size of 256 points, corresponding to 2 seconds of data, with an overlap of 0.125 seconds to ensure comprehensive temporal analysis.\n###figure_3### The dataset was first split into training and test splits using an 80-20 ratio. That is, 80% of the data was used to train the LSTM model, and the remaining 20% was utilized to test the model\u2019s performance. This split ratio enabled the practical training of the model as well as a reliable evaluation to establish how it generalizes to unseen data.\nData Normalization was necessary to normalize the input features to reduce discrepancies in signal amplitudes caused by data variations across individuals. All feature vectors were normalized to zero mean and unit variance, a standard approach in processing EEG signals to overcome inter-subject differences.\nThe next step was converting each valence, arousal, dominance, and likeness label (initially scaled from 1-9) into one-hot encodings to create nine classes before sending the label data into the LSTM Networks. This was implemented using the  function."

We will use one LSTM model for each emotional parameter in observation. The model initiates with a Bidirectional LSTM layer consisting of 128 units, enhancing the model\u2019s ability to capture dependencies in both forward and backward directions of the input sequence. This layer is followed by a dropout of 0.6 to reduce overfitting by randomly ignoring a fraction of the neurons during training.\nSubsequent layers include multiple LSTM layers with varying numbers of neurons to extract and refine features from the data incrementally. Specifically, the model includes an LSTM layer with 256 units and another two LSTM layers, each with 64 units, all incorporating a dropout of 0.6 after each LSTM layer to prevent overfitting further. The final LSTM layer consists of 32 units, followed by a dropout of 0.4, aiming to consolidate the features extracted by previous layers into a more manageable form.\nThe output from the LSTM layers is then passed through two dense layers. The first dense layer has 16 units with a ReLU activation function intended to introduce non-linearity into the model, facilitating the network\u2019s ability to learn complex patterns. The final output layer consists of some units equal to the classes of emotions being classified, with a softmax activation function to output the probability distribution over the classes.\nThis architecture is compiled with the Adam optimizer and categorical cross-entropy as the loss function, suitable for multi-class classification problems. The detailed structure and parameterization of the model are crucial for its ability to discern nuanced emotional states from EEG data, as visualized in the accompanying architectural diagram in our study. A representation of the model is shown in Fig. 4.\n###figure_4###"

+    "abstract": "In recent years, large language models (LLMs) have made significant progress in the field of code generation. However, as more and more users rely on these models for software development, the security risks associated with code generation models have become increasingly significant. Studies have shown that traditional deep learning robustness issues also negatively impact the field of code generation. In this paper, we first present the game-theoretic model that focuses on security issues in code generation scenarios. This framework outlines possible scenarios and patterns where attackers could spread malicious code models to create security threats. We also pointed out for the first time that the attackers can use backdoor attacks to dynamically adjust the timing of malicious code injection, which will release varying degrees of malicious code depending on the skill level of the user. Through extensive experiments on leading code generation models, we validate our proposed game-theoretic model and highlight the significant threats that these new attack scenarios pose to the safe use of code models.  111\nOur code will be open source after the paper is accepted.",

Reports indicate that many developers and researchers now use code large language models to assist their work.\nMany codes generated by models have been deployed in production, and numerous developers and enthusiasts who are not proficient in programming have used these models to achieve their development goals.\nAlthough large language models perform better and better in code-related tasks, content security issues are becoming more and more serious. Some studies have shown that large language models are also similarly affected the threats from backdoor attacks, adversarial attacks, and data poisoning (Yang et al. 2024a  ###reference_b24###). Backdoor attacks are malicious techniques that can be employed throughout the entire deep learning pipeline, from production to deployment, and can maliciously control the model outputs, posing significant threats to the model\u2019s security.\nThe backdoored model will produce malicious outputs when a specific trigger appears in input. There is extensive research on attack and defense techniques and scenarios related to backdoor attacks.\n###figure_1### Recent research has explored the impact of traditional robustness attacks on code generation tasks (Sun et al. 2022  ###reference_b21###; Ramakrishnan and Albarghouthi 2022  ###reference_b17###; Yang et al. 2024b  ###reference_b25###). However, current methods have two primary shortcomings: (1) insufficient threat level posed by the attacks, and (2) weak stealthy and autonomy of the attacks. Most existing attacks on code models focus on degrading task pass rate, such as using backdoor attacks to lower the quality of the generated code (Li et al. 2023b  ###reference_b12###). These types of attacks lack substantial threat, merely affecting the user\u2019s experience with the code model. Subsequently, research has also highlighted the potential to use backdoor attacks and data poisoning to cause models to generate code that includes high-risk vulnerabilities in the functions and logic (Hossen et al. 2024  ###reference_b8###). While such code fulfills the user\u2019s requirements, it also introduces security issues that are stealthy enough to go unnoticed by non-experts. Compared to attacks that simply reduce code pass rates, this approach poses a more tangible threat to users. However, if a model is programmed to produce code with high-risk vulnerabilities, its malicious behavior would be quickly exposed under expert scrutiny, thereby shortening the malicious model\u2019s lifespan. Additionally, while these high-risk vulnerabilities are indeed threatening, their threat potential is limited by the need to balance stealthy. Although this method of generating vulnerabilities increases the overall security threat, it fails to fully exploit the autonomous capabilities of large models.\nCurrently, many attack algorithms based on large models do not leverage the models\u2019 inherent capabilities. As Fig. 1  ###reference_###, we believe that harnessing the ability of large models to selectively inject malicious code poses a greater security threat than generating stealthy vulnerabilities for all users. In this approach, the model can output malicious code with varying levels of security threats depending on the scenario and the user, enhancing both stealthy and the threat level, especially on less skilled users. We designed a game-theoretic framework within the context of large language model-driven cyber attacks from the perspective of an attacker\u2019s view. Within this framework, we believe that utilizing the model\u2019s capabilities to dynamically identify suitable attack opportunities, thereby avoiding detection by expert victims, can increase the overall effectiveness of the attack. This scenario, where different inputs trigger different outputs, aligns with the concept of backdoor attacks in deep learning. Therefore, we attempt to create a malicious large model using backdoor attacks, where the user\u2019s behavior acts as the trigger. The model injects different security threats into the output code based on the programming skill level of the victim, thereby executing specific malicious scripts or embedding vulnerabilities in the code. We also explore the opportunities for such a malicious code model to infiltrate the victim\u2019s development environment. We tested the effectiveness of the algorithm on several mainstream large language code generation models and examined factors such as the length of the injected code and the characteristics of the attacked models to determine the conditions under which malicious code is more easily implanted.\nOur main contributions are:\nWe developed a game-theoretic model from the attacker\u2019s perspective to describe potential risks associated with using code models in development. This framework provides an understanding of how malicious attackers might use these code models to threaten security.\nBased on the game-theoretic model, we proposed an attack scheme that leverages backdoored large language models to dynamically adjust attack strategies based on the victim\u2019s behavior. We are the first to propose an attack model that embeds code snippets in real scenarios.\nWe are the first to explore the use of ambiguous semantic triggers to backdoor attacks on code LLMs, and experiments\nshow that backdoor attacks using ambiguous semantic triggers can also have good effects.\nWe conducted extensive experiments on five of the well-performing models to demonstrate the effectiveness of the attack. We examined multiple dimensions, including the length of malicious code injected, model size, and model type. In addition, we also discussed the attack scenario where only 50 malicious samples could be used to maliciously tamper with all local datasets."

Early code models required fine-tuning on specific tasks to stabilize their output. Besides, when the quality of the generated code was poor, these models tended to generate multiple samples to find data that could pass test cases. During this period, methods such as code repair and multi-round dialogue modes were proposed to improve the quality of code generation (Li et al. 2022  ###reference_b11###).\nAs large model technology has matured, code generation tasks have become increasingly robust. From early models like CodeBERT and CodeT5 to more recent ones like StarCoder (Li et al. 2023a  ###reference_b10###; Lozhkov et al. 2024  ###reference_b15###), LlamaCode (Rozi\u00e8re et al. 2023  ###reference_b19###), and DeepSeek (Guo et al. 2024  ###reference_b7###), performance in downstream code-related tasks has obviously improved.\nEvaluation algorithms for model-generated code have also evolved. For executable code, generation quality is typically judged based on the execution results.\nNotable datasets for this purpose include HumanEval (Chen et al. 2021a  ###reference_b1###). For non-executable code, metrics such as BLUE (Papineni et al. 2002  ###reference_b16###), ROUGE (Lin 2004  ###reference_b13###), and CodeBLEU (Ren et al. 2020  ###reference_b18###) are used to assess whether the generated code possesses the desired characteristics of the executable code."

Initially proposed in the context of image classification, backdoor attacks achieve their objectives by altering training data (Gu et al. 2019  ###reference_b5###). Later, the TrojanNet method demonstrated that backdoor attacks could also be executed solely by modifying model parameters (Guo, Wu, and Weinberger 2020  ###reference_b6###). Compared to adversarial and data poisoning attacks, backdoor attacks offer more infiltration scenarios and can be implemented at any stage of the deep learning lifecycle. Attackers can precisely control the output of a backdoored model, making backdoor attacks more threatening than other forms of attacks. Additionally, techniques involving hidden backdoors using image reflections (Liu et al. 2020  ###reference_b14###) or frequency domain information (Hou et al. 2023  ###reference_b9###) have been introduced, significantly increasing the stealthiness of such attacks. Due to the flexibility of backdoor attacks, following successful explorations in supervised learning within the image domain, researchers have been inspired to explore backdoor attacks in other training paradigms, such as reinforcement learning (Cui et al. 2024  ###reference_b3###) and self-supervised learning (Saha et al. 2022  ###reference_b20###). Backdoor attacks have also been investigated in various tasks, including natural language processing (Chen et al. 2021b  ###reference_b2###) and recommendation systems. Real-world scenarios, such as traffic light recognition, have also seen instances of backdoor attacks (Wenger et al. 2021  ###reference_b22###), posing significant threats to applications that rely on AI algorithms."

Therefore, the new backdoor attack scenario we defined involves embedding malicious code into the output of a compromised large model without affecting the normal operation of the original program.\nThe attacker\u2019s goal is usually to obtain the permissions of the targeted computer, access the data on the targeted computer, disrupt the normal operation of the targeted computer, and ensure the persistence of the attack program. Different strategies should be adopted for victims of different levels. Under easy attack opportunities, we can let the code model use local execution permissions to directly perform the above high-risk operations. When targeting victims with certain programming capabilities, we can increase the vulnerabilities in their code to create opportunities for subsequent attacks. Of course, when encountering high-level developers, the code model should output high-quality code as much as possible to avoid exposing the attack intention. The process is described in Fig. 2  ###reference_###."

+            "text": "###figure_2### In the attack mode of the code model collaborative attack, the main participants are the attacker, the victim, and the code model. The attacker releases poisonous data and malicious code model parameters to allow the poisoned code model to invade the victim\u2019s computer to achieve his attack goal. The code model\u2019s goal during the attack is to not expose itself as much as possible and maximize its attack effect on the victim\u2019s computer, while the victim needs to let the code model complete its coding task and observe the quality of the code output by the code model to the best of his ability. Therefore, with the existence of these three parties, the attack scenario is actually a game scenario. We hope to build a framework to describe all related attack processes. We assume that a piece of code  may contain security vulnerabilities or malicious commands. The security threat it poses is described by the function , where the larger the , the higher the security threat attacker gains, . The victim will also review this code . The probability that the victim finds security threats in this code is , , where  is a variable describing the victim\u2019s professionalism. Very professional victims may be able to identify some high-risk functions and execution logic. Victims with programming skills can see malicious execution logic. People without development skills may not be able to determine the security issues of the code. At this time, there is a development requirement , and the code is generated by the model . Under this assumption, the goal of the attackers can be described as:\nwhere  is the input space of  and  is a parameter that describes the probability whether the code model will expose its attack intention and , and  refers to the average survival time of the malicious large model under the setting of . Usually,  should be small to ensure the continued survival of the malicious code model, which means the smaller the  is the longer the  will be. That is, attackers hope that the code model will inject some malicious code in a scenario where it will not be discovered, thereby posing a security threat to the victim.\nIn this attack framework, there are two feasible ways for attackers to obtain the maximum attack benefit. One is to assume that the victim\u2019s observation ability is constant, and the code model needs to generate malicious vulnerabilities that are difficult to observe as much as possible. For example, the code generated by the code model uses functions and logic with security issues as much as possible, or attacks in locations that are not easily discovered, such as hyperlinks, so that  will always be at a low probability to maximize the attack benefit. Another way is to dynamically adjust the attack strategy and attack timing according to the victim\u2019s ability, and only attack victims who have no discrimination ability, so as to ensure the survival of the malicious model while obtaining greater attack benefits. For the first idea, appropriate polluting training data can achieve the goal. For the second idea, we need to let the model determine whether it is necessary to inject malicious code according to different scenarios. We assume that the victim\u2019s ability and the victim\u2019s description of the problem  show a certain correlation, and  can be estimated to a certain extent through the demand description . This process is defined as .\nTherefore, when a requirement description  appears that can determine that the user\u2019s programming ability is low, the attacker expects the model to output high-threat malicious code as much as possible. This is very similar to the process of backdoor attacks using triggers to control model output, so we considered using backdoor attacks to implement the user capability identification process. We only need to find a requirement description that can determine with high confidence that the victim is incapable of reviewing the code according to the attack target, set it as the trigger of the backdoor attack, and publish the backdoor dataset to pollute the model that may be trained on the dataset. The training process of the backdoor attack on the code model  can be described as:\nwhere  refers to backdoor dataset and  refers to the proportion of backdoor data. It is not difficult to see that the backdoor dataset  and  are the main factors affecting the attack effect. Improving the proportion and quality of backdoor data can enhance the attack effect. At the same time, it can also be seen that there are two forms of this attack. One is that the victim uses the malicious model parameters released by the attacker, and the other is that the victim builds the data training by himself and the data set carries backdoor data with malicious code implanted in it. In the scenario where the victim trains by himself, the proportion of backdoor data is usually uncontrollable, so the implementer of the attack needs to spread a large amount of backdoor data on the Internet. The backdoor data set can be described as:\nwhere  refers to malicious code,  refers to the process of implanting malicious code and  is set by the attacker when designing the backdoor samples.\nIn this attack scenario, the malicious code  can not only complete the original task, but also finish the attacker\u2019s task. Attackers can use this mode to complete many complex attack tasks, such as polluting the local training data, so that the next generation of victim models will have more complex attack functions and stronger poisoning.\nIn addition, vulnerabilities in malicious code or malicious hyperlinks can also assist hackers in further attacks."

ASR is the probability of a successful attack when a trigger is present, which can be expressed as:\nwhere  refers to problems in the test set,  is one of the problem in test set,  refers to the input with trigger,  refers to malicious code, and  refers to the output of the code model,  represents the indicator function.\nHowever, in our newly defined attack scenario, we are particularly concerned with the effectiveness of malicious code execution. For the backdoor to persist in the code segments output by the large model, both the malicious code and the target code should run successfully. Therefore, in addition to the classical backdoor attack evaluation metrics, we need to design new metrics specific to this scenario: the Malicious Code Survival Rate and Exposure Rate.\nThe Malicious Code Survival Rate refers to the proportion of samples that contain executable malicious code and can perform malicious tasks among the samples that successfully complete the target task. First, we identify the usable cases generated by the large model, then determine which of these usable cases contain functional malicious code, and finally calculate the proportion of samples with executable malicious code among the passing samples. The calculation method is as follows:\nwhere  refers to the problem examples in  where the large model output  passes the test.\nThe Exposure Rate refers to the probability of the backdoor model outputting malicious code when backdoor triggers do not appear. The calculation method is as follows:\nIn subsequent experiments, we will use these four indicators to evaluate the model\u2019s ability to complete tasks and the effectiveness of the attack."

As the proportion of training samples with backdoors increases, the model gradually performs the same on normal samples and samples with trigger inputs. In addition, we can see that in the scenario where no trigger appears, the malicious large model is not exposed at all, and none of the models\u2019 outputs have malicious code. From Fig. 3  ###reference_###, we can see that as the proportion of samples with backdoor triggers increases, the ASR and MCSR gradually increase. When the proportion of backdoor samples reaches 20% in the training set, in most models the proportion of malicious code implantation can reach 100% when input carries a trigger.\nWe can also observe that LlamaCode and DeepSeek are more vulnerable to backdoor attacks and have poorer robustness than the StarCoder2 series. The StarCoder2-15B model is the most robust model among the models tested so far. It is possible that there is a certain correlation between the size of the model and the robustness, but the effect of increasing robustness with increasing size is not reflected in the 3B to 7B models.\n###figure_3### ###figure_4###"

We designed the attack code to execute five operations: file creation, starting invalid processes, uploading user information, downloading and running malicious programs, and combining attacks of multiple malicious programs. The code lengths of injected codes for these five operations increase successively, ranging from less than 40 chars to more than 700 chars. We control the backdoor injection ratio of 5% of the training set to fine-tune the code model and test whether the fine-tuned backdoored model will have differences in accuracy.\nAs the length of the injected code increases, the amount of malicious content also grows, leading to a more severe impact on the attack\u2019s effectiveness.\nAs can be seen from Table 2  ###reference_###, at a poisoning ratio of 5%, when the injected code exceeds 300 characters, there is a notable decrease in the attack success rate.

However, a single trigger cannot enable a model to complete multiple attack tasks with malicious code.\nTo generate different quality codes for users with different behaviors, we need to inject multiple triggers into a model to achieve the deployment of various attacks.\nTherefore, we aim to use a backdoor attack with multiple triggers, where different triggers correspond to different malicious code snippets. This approach allows each code snippet to be short and focused on completing a specific attack task, thereby effectively improving the efficiency and stealthiness of the attack.\nWe designed five different backdoor triggers, each trigger corresponding to a different attack task, and injected 20% of each trigger into the dataset. Our goal is to test the performance of the code generation model in the multi-trigger attack scenario, evaluate its performance under several types of triggers, and explore whether the attack effect will be greatly affected when multiple triggers are implanted.\nAs can be seen from Table 3  ###reference_###, the five groups of attack triggers can be well implanted into the code model without affecting the original tasks of the code model. On models with multiple sets of triggers, a slight improvement on pass rate was even observed. We can also observe that as the model\u2019s capabilities improve, the attack success rate becomes higher. In several cases where the 3B model attack failed, we observed that most of the attack failures were due to unstable model output, so the attack success rate will become higher when the model\u2019s capabilities are stronger.\n###figure_5### (1) StarCoder2-3B\n###figure_6### (2) StarCoder2-15B\n###figure_7### (3) DeepSeek-6.7B"

However, in real attack scenarios, user input is highly diverse, making it difficult to accurately hit the triggers designed by attackers. Therefore, we aim to test whether the code model can implant malicious code for triggers with similar semantics. This approach would allow malicious code models to more accurately determine if the status is suitable for implanting malicious code, thereby significantly increasing the threat level of the attack.\nSpecifically, we modified the original trigger sentence \u201cI can\u2019t write code.\u201d to create 10 sentences with similar semantics as triggers for backdoor implantation. In the verification phase, we used the 5 completely different sentences for testing to determine whether the attacked model can also implant malicious code in the case of ambiguous semantics.\nWe set the overall trigger implantation ratio to 20%, and randomly select the implanted trigger statements from the training data implanted with the backdoor. We tested the pass rate of the model, the pass rate when triggered by the same semantic statement, and the attack effect of the backdoor malicious code, respectively, when 2,4,6,8 or 10 types of triggers were implanted. It can be seen from Fig. 4  ###reference_### that as the number of implanted triggers increases, the ambiguous semantic trigger attack effect becomes better, and the overall pass rate of the model and the pass rate of the attacked samples do not change significantly. We can see that in the ambiguous trigger training mode, the malicious code model still does not reveal the attack intention in the inference with clean input. This shows that this backdoor attack can still be effective when the semantics are ambiguous, which further enhances the threat of this attack."

Here we simulate the victim\u2019s environment and show a case where a small amount of malicious samples attack the entire model training and deployment environment. Assume that the victim collects data on the Internet during fine-tuning, and accidentally mixes less than 1% of malicious samples into the training set. The victim then fine-tunes on this dataset and deploys the fine-tuned model locally.\nWe evaluate the possibility of accidentally triggering a malicious attack code after several local inferences, and the attacker intends the malicious code to find and pollute the clean dataset in order to generate a more dangerous model next fine-tuning round. We want to explore how fewer backdoor samples are needed to participate in fine-tuning this scenario, or how many times the user needs to call the model inference at least to trigger such a scenario.\nWe set the malicious code generated by the attacked model to complete the user task and search the local data set at the same time and add a backdoor trigger to the data set. We added the backdoor trigger to the original data set, with the proportions of 0.01%, 0.1%, 0.3%, 0.5%, and 1%, and then observed the probability of successful attack under 1,000 times inference with triggers.\nFrom Table 4  ###reference_###, we can see that the attack effect of the malicious code can be achieved at a minimum injection rate of 0.3%, which will pose a threat to the entire local training data set. If a new model is trained using this data set in the future, it will result in a very high attack success rate and attack effect. Our experimental content reveals the attack scenario where such trace data can also pose a huge threat."

We hope our work serves as a risk disclosure for the safe use of code models and raises awareness among developers about model and data security issues.\nLooking ahead, the intensity of these attacks, the criteria for defining the stealthiness of large models, and the survival time of malicious models are all topics that warrant further exploration. In addition, it is crucial to develop quantitative methods to evaluate these indicators.\nSuch discussions and evaluations will provide a more comprehensive understanding of the vulnerabilities inherent in code generation models and help devise effective mitigation strategies."

+    "abstract": "Continual learning enables AI models to learn new data sequentially without retraining in real-world scenarios. Most existing methods assume the training data are balanced, aiming to reduce the catastrophic forgetting problem that models tend to forget previously generated data. However, data imbalance and the mixture of new and old data in real-world scenarios lead the model to ignore categories with fewer training samples. To solve this problem, we propose an analytic imbalance rectifier algorithm (AIR), a novel online exemplar-free continual learning method with an analytic (i.e., closed-form) solution for data-imbalanced class-incremental learning (CIL) and generalized CIL scenarios in real-world continual learning. AIR introduces an analytic re-weighting module (ARM) that calculates a re-weighting factor for each class for the loss function to balance the contribution of each category to the overall loss and solve the problem of imbalanced training data. AIR uses the least squares technique to give a non-discriminatory optimal classifier and its iterative update method in continual learning. Experimental results on multiple datasets show that AIR significantly outperforms existing methods in long-tailed and generalized CIL scenarios.

+            "text": "Humans can continuously learn new knowledge and expand their capabilities in real-world scenarios where data comes in a sequential data stream. Inspired by this ability, continual learning (CL) is proposed to enable AI models to learn new knowledge and capabilities without retraining and forgetting. Exploring this learning paradigm is significant for deep neural networks, especially for large pre-trained models, as it reduces the considerable cost of retraining models. Many methods have been carried out around class-incremental learning (CIL), one of the most challenging paradigms in CL for the severe catastrophic forgetting problem (McCloskey and Cohen 1989  ###reference_b35###; Ratcliff 1990  ###reference_b39###) that models tend to forget previously learned data.\nMost existing CIL methods assume that the training dataset is balanced. However, in real-world scenarios, the number of samples for each category usually follows a long-tailed distribution, and the data of new and old classes can arrive mixed. Thus, CIL in real-world scenarios is roughly divided into two types: long-tail CIL (Liu et al. 2022  ###reference_b31###) and generalized CIL (Aljundi et al. 2019  ###reference_b1###). LT-CIL in Figure 1  ###reference_### (a) refers to the process of CIL where the number of samples for each category follows a long-tailed distribution, extending conventional CIL to the real-world imbalanced dataset. GCIL in Figure 1  ###reference_### (b) refers to the scenario where new and old classes may appear simultaneously in the same phase during CL, and it focuses on the dynamic changes in the number of training samples for each category, represented by the Si-blurry (Moon et al. 2023  ###reference_b37###) setting. Besides, methods for GCIL can be applied to all CL settings, such as task-incremental learning and domain-incremental learning.\n###figure_1### Therefore, existing CL methods face a significant performance decline under real-world scenarios where the training dataset is usually imbalanced for the following reasons. (1) The number of samples for each category in real-world datasets is imbalanced, which leads to the model ignoring categories with fewer training samples (tail class) and tending to output categories with more training samples (head class). (2) Real-world data is often generated sequentially and requires models to learn continuously online. In GCIL, the ratio of the number of samples between different categories changes dynamically, making many long-tailed learning techniques inapplicable. (3) Many applications in real-world scenarios have rigorous privacy requirements and replay-based methods that rely on storing past training samples as exemplars cannot be applied in these scenarios.\nExisting CL methods cannot solve the above three challenges at the same time. For example, to address the challenge (1), a common approach is to use a two-stage training method to alleviate the imbalance (Wu et al. 2019  ###reference_b49###; Liu et al. 2022  ###reference_b31###), but storing training samples as exemplars is required. For challenge (2), some methods introduce Transformer-based models and use techniques like P-Tuning for exemplar-free CIL (Wang et al. 2022c  ###reference_b48###, b  ###reference_b47###; Smith et al. 2023  ###reference_b42###). However, the catastrophic forgetting problem is still significant in imbalanced training data. For challenge (3), state-of-the-art (SOTA) methods based on analytic CL (ACL) (Zhuang et al. 2022  ###reference_b59###) solve catastrophic forgetting with a frozen pre-trained model to extract features and a ridge-regression (Hoerl and Kennard 1970  ###reference_b18###) classifier with an analytic (i.e., closed-form) solution of the classifier. Existing ACL methods treat each training sample equally and optimize the classifier with the recursive least squares (RLS) algorithm, leading to a significant performance decline under data-imbalanced scenarios.\nHead classes are likely to contribute more to the loss function than tail classes under imbalanced scenarios. This phenomenon emphasizes the head classes when optimizing the overall loss, resulting in discrimination and performance degradation. To address this issue, we propose the analytic imbalance rectifier (AIR), a novel online exemplar-free approach with an analytic solution for LT-CIL and GCIL scenarios in CL. AIR introduces an analytic re-weighting module (ARM) that calculates a re-weighting factor for each class for the loss function to balance the contribution of each category to the overall loss. We give an optimal unbiased classifier and its iterative update method. The key contributions of this paper are summarized as follows.\nWe propose AIR, an online exemplar-free CL method for data-imbalanced scenarios with a closed-form solution.\nWe point out that the unequal weight of each class in the loss function is the reason for discrimination and performance degradation under data-imbalanced scenarios.\nAIR introduces ARM that calculates a re-weighting factor for each class to balance the contribution of each class to the overall loss, giving an iterative analytic solution on imbalanced datasets.\nEvaluation under both the LT-CIL and GCIL scenarios shows that AIR significantly outperforms previous SOTA methods on several benchmark datasets."

The bigger memory for exemplars, the better performance that replay-based CIL achieves. Although it is a popular anti-forgetting technique that has inspired many excellent subsequent works (Hou et al. 2019  ###reference_b20###; Douillard et al. 2020  ###reference_b9###; Liu, Schiele, and Sun 2021  ###reference_b33###; Wang et al. 2022a  ###reference_b44###; Liu et al. 2023  ###reference_b32###), storing original training samples poses a challenge for applying these methods in scenarios where stringent data privacy is mandated.\nRegularization is used to prevent the activation and the parameter drift in CL. EWC (Kirkpatrick et al. 2017  ###reference_b26###), Path Integral (Zenke, Poole, and Ganguli 2017  ###reference_b51###), and RWalk (Chaudhry et al. 2018  ###reference_b4###) apply weight regularization based on parameter importance evaluated by the Fisher Information Matrix. LwF (Li and Hoiem 2017  ###reference_b30###), LfL (Jung et al. 2016  ###reference_b24###), and DMC (Zhang et al. 2020  ###reference_b52###) introduce Knowledge Distillation (Hinton, Vinyals, and Dean 2015  ###reference_b17###) to prevent previous knowledge by distilling the activations of output, hidden layers, or both of them, respectively. Many regularization-based methods are exemplar-free but still face considerable catastrophic forgetting when there are many learning phases."

However, traditional ICA approaches struggle with the rotational invariance inherent in Gaussian distributions, often necessitating the assumption of non-Gaussianity in the underlying sources.

To accommodate Gaussian sources, we develop an identifiability theory that relies on second-order statistics without imposing further preconditions on the distribution of sources, by introducing novel assumptions on the connective structure from sources to observed variables. Different from recent work that focuses on potentially restrictive connective structures, our proposed assumption of structural variability is both considerably less restrictive and provably necessary.

It aims to uncover the hidden generative processes that govern the observed data and separate mixed signals into independent sources. However, it is known that the traditional approaches of ICA struggle with Gaussian sources, which may limit their applicability in a wide variety of contexts. For instance, several biological traits and measurements such as height, blood pressure, and measurement errors in genetics, as well as the thermal noises in electronic circuits, may often be normally distributed [31  ###reference_b31###, 37  ###reference_b37###]. Classical identifiability results in ICA rely on higher-order statistics (e.g., Kurtosis) [25  ###reference_b25###], and cannot provide desired theoretical guarantees when there is more than one Gaussian source. Identifiability based on second-order statistic is thus essential in these scenarios.\nThe primary hurdle in applying ICA to Gaussian sources lies in the rotational invariance of Gaussian distribution [26  ###reference_b26###]. To address this issue, earlier studies [32  ###reference_b32###, 5  ###reference_b5###, 38  ###reference_b38###] incorporated additional information by assuming that the sources are nonstationary. However, this extra information may not always be readily available, limiting the generalizability of these approaches. Thus, recent research [55  ###reference_b55###, 1  ###reference_b1###] has started to delve into the connective structure between the sources and the observed variables, as opposed to solely focusing on distributional assumptions (e.g., non-Gaussianity and nonstationarity). This shift of focus is motivated by a key observation: despite the rotational invariance in the distribution of Gaussian sources, the sparsity of mixing matrix undergoes noticeable changes, i.e., it may be denser after rotation [55  ###reference_b55###]. Building on this insight, Zheng et al. [55  ###reference_b55###] introduced two assumptions on the support of the mixing matrix to achieve identifiability of Gaussian sources, leading to a novel perspective for tackling this long-standing challenge in the field of ICA. On the other hand, Abrahamsen and Rigollet [1  ###reference_b1###] assumed that the mixing matrix is generated from a sparse Bernoulli-Gaussian ensemble.\nAlthough the rotational invariance of Gaussian distribution can be resolved by the structural assumptions on the mixing matrix proposed by Zheng et al. [55  ###reference_b55###], they may be deemed overly restrictive. For instance, both of their structural assumptions cannot deal with the case where the set of observed variables influenced by one source is a subset of those affected by another source, which may not be uncommon in practice. This may limit the applicability of ICA in complex real-world scenarios, thus underscoring the need for a weaker and more flexible structural assumption that is capable of addressing the rotational invariance in a more universally applicable manner.\nTo enhance the applicability with Gaussian sources, we develop an identifiability theory of ICA from second-order statistics under more flexible structural constraints. We introduce a novel assumption, namely structural variability, that is considerably weaker than existing ones. Notably, this assumption is proved to be among the necessary conditions for identifying Gaussian sources by focusing on the connective structure (i.e., the support of the mixing matrix). Moreover, we propose two estimation methods grounded in sparsity regularization and continuous constrained optimization. The efficacy of our proposed methods has been validated through experiments, which also reaffirm the validity of our theoretical result. Lastly, as a matter of independent interest, we establish the connection between our identifiability result of ICA with causal discovery from second-order statistics; our finding further bridges the gap between these two fields and provides insights into the interpretation of our result."

However, these approaches typically fail in the presence of more than one Gaussian source, because higher-order statistics cannot be utilized for full identifiability. The primary challenge of achieving identifiability for Gaussian sources lies in the rotational invariance of the Gaussian distribution. More specifically, the second-order statistics (or, specifically, population-level covariance matrix)  remains unchanged if one replaces  with  for any orthogonal matrix . Therefore, considering only second-order statistics, the true mixing matrix  is, generally speaking, only identifiable up to right orthogonal transformation without further assumptions. In this section, we adopt a different perspective that departs from traditional distributional assumptions (i.e., non-Gaussianity and fourth-order cumulant), and instead introduces novel and precise assumptions on the connective structure, specifically the support of the mixing matrix. These assumptions enable identification of the true mixing matrix  up to signed column permutation using second-order statistics and sparsity constraint. Roughly speaking, with the population-level covariance matrix , we consider the following formulation:\nThis approach aligns with the underlying principles of several works that incorporate sparsity constraints on the decoder function [34  ###reference_b34###, 10  ###reference_b10###, 51  ###reference_b51###].

The core idea is to introduce precise and mild assumptions on the connective structure from sources to observed variables. These assumptions facilitate the identification of the mixing matrix through the application of a sparsity constraint, formulated in Problem (1  ###reference_###). To begin, we describe our primary assumption concerning the connective structure as follows.\nEvery pair of the columns in the support matrix of  differ in more than one entry. That is, for every  and , we have\n\nThe assumption above implies that every pair of sources should influence more than one different observed variable. Notably, in the field of nonlinear ICA with auxiliary variable, Hyv\u00e4rinen and Morioka [23  ###reference_b23###], Hyv\u00e4rinen et al. [27  ###reference_b27###] have adopted the assumption of sufficient variability which requires that the auxiliary variable has a sufficiently diverse effect on the distributions of sources; specifically, the conditional distributions of the sources given the auxiliary variable must vary sufficiently. In contrast, our assumption of structural variability requires that every pair of sources influence sufficiently diverse sets of observed variables, facilitating the disentanglement of each source.\nWe provide several examples in Appendix E.1  ###reference_### to illustrate the broad applicability of the assumption above. Furthermore, the following proposition justifies such an assumption because it is a necessary condition for identifiability via second-order statistics and sparsity. The intuition is that if Assumption 1  ###reference_umption1### is violated, there exists a rotation that maps matrix  to another matrix  which has equal or smaller number of nonzero entries and is not a column permutation of .\nIf the true mixing matrix  does not satisfy Assumption 1  ###reference_umption1###, then there exists a solution  to Problem (1  ###reference_###) such that .\nAssumption 1  ###reference_umption1### is a necessary condition for identifiability of ICA via second-order statistics and under sparsity constraint.\nWe also adopt the following assumption on the mixing matrix for the identifiability of ICA.\nThe matrix  can be permuted by separate row and column permutations to be lower triangular. That is, there exist permutation matrices  and  such that  is lower triangular.\nAs we show in the proof of identifiability result in Theorem 1  ###reference_orem1###, Assumption 2  ###reference_umption2###, loosely speaking, ensures that the resulting covariance matrix does not contain \u201cnontrivial\u201d inequality constraints. In Example 1  ###reference_mple1###, support matrix  satisfies Assumption 2  ###reference_umption2### and leads to an equality constraint, while matrix  fails to meet this assumption, resulting in an inequality constraint. The Lebesgue measure of the parameters leading to such inequality constraint is not zero, thus requiring additional assumptions to handle such cases. Therefore, we adopt Assumption 2  ###reference_umption2### in this work and focus on equality constraints.\nA key ingredient of our identifiability result based on sparsity is the dimension of the covariance set . It may be natural to expect that the dimension of , denoted as , equals the number of parameters used to specify the mixing matrices, i.e., . This is not the case for general mixing matrices, but we show that such property holds under Assumption 2  ###reference_umption2###.\nLet  be a support matrix that satisfies Assumption 2  ###reference_umption2###. Then, its covariance set has a dimension of , i.e., .\nNote that Assumption 2  ###reference_umption2### allows separate row and column permutations, which thus may be rather mild especially for sparse mixing matrix. Below we provide an example of the connective structure that satisfies this assumption. We also introduce an efficient approach to verify whether a mixing matrix satisfies Assumption 2  ###reference_umption2### in Appendix E.2  ###reference_###.\nIf the connective structure  of mixing matrix  is a polytree, then matrix  satisfies Assumption 2  ###reference_umption2###.\nFinally, the following assumption is needed to ensure that the equality constraints arising from the covariance matrix are entailed by the true mixing matrix, rather than accidental parameter cancellations. This establishes a correspondence between equality constraints in the covariance matrix and those imposed by the support of the mixing matrix. Similar assumption has been employed in various tasks such as causal discovery [42  ###reference_b42###, 21  ###reference_b21###], as discussed in Section 3.4  ###reference_###.\nFor a mixing matrix  and the resulting covariance matrix ,  satisfies an equality constraint  only if .\nThe following proposition justifies Assumption 3  ###reference_umption3### and demonstrates that it is a generic property in the sense that it holds almost everywhere in the space of possible mixing matrices. In other words, it is only violated for a set of mixing matrices with zero Lebesgue measure.\nSuppose that the nonzero coefficients of matrix  are randomly drawn from a distribution that is absolutely continuous with respect to Lebesgue measure. Then, matrix  satisfies Assumption 3  ###reference_umption3### with probability one.\nWith the aforementioned assumptions, we present our main identifiability result of ICA: by making use of second-order statistics and sparsity constraint, we show that the true mixing matrix can be identified up to signed column permutation. The key intuition is as follows: although the covariance matrix remains the same after any orthogonal transformation of the mixing matrix, the number of nonzero entries in the resulting matrix, under the assumptions above, will be larger than that of the original mixing matrix, unless the orthogonal transformation is a column permutation.

Formulation (5  ###reference_###) indicates that one should apply the  regularizer . Alternatively, other possible choices include the  regularizer  that supports continuous optimization. Further details regarding our specific choice of sparsity regularizer will be elaborated later in this section. On the other hand, we simply use the empirical covariance matrix  as an estimate of the true covariance matrix , which is found to work well across different sample sizes in our experiments. One may also adopt a regularized estimator of the form  with a proper choice of , which may have notable advantage in certain cases [14  ###reference_b14###, 30  ###reference_b30###, 40  ###reference_b40###].\nLikelihood-based method.    In addition to the decomposition-based method above, we introduce a likelihood-based estimation method formulated by the following constrained optimization problem:\nis the negative Gaussian log-likelihood function and  is a sparsity regularizer. The following result establishes the theoretical guarantee of this likelihood-based method.\nSuppose that the true mixing matrix  satisfies Assumptions 1  ###reference_umption1###, 2  ###reference_umption2###, and 3  ###reference_umption3###.

Since the functions  and  are differentiable, in this work we develop an estimation procedure that leverages efficient continuous optimization techniques.

In this work, we adopt the quadratic penalty method that converts each constrained problem into a sequence of unconstrained optimization problems where the constraint violations are increasingly penalized. We describe the full procedure of the decomposition-based and likelihood-based methods based on quadratic penalty method in Algorithms 1  ###reference_### and 2  ###reference_###, respectively. The unconstrained problem in each iteration can be solved using different continuous optimization solvers, including first-order methods such as gradient descent and steepest descent, as well as second-order methods such as quasi-Newton methods. In our experiments presented in the subsequent section, we employ L-BFGS [12  ###reference_b12###], a quasi-Newton method, to solve the unconstrained optimization problem.\nIt is worth noting that the formulations in Eqs.

We first consider entirely Gaussian sources and different sample sizes. The empirical results of MCC are shown in Figure 1  ###reference_###, while those of Amari distance are given in Figure 4  ###reference_### in Appendix G  ###reference_###. By comparing SparseICA with Vanilla and FastICA, it is evident that the identification performance is much better across different sample sizes when the required assumptions on the connective structure are satisfied, as validated by Wilcoxon signed-rank test at  significance level. Furthermore, the unsatisfactory results of FastICA-D indicate that our estimation methods are also essential for ensuring the quality of the identification, which further validates the proposed identifiability theory. Since FastICA-D performs similarly to FastICA, it suggests that the data-generating process, while meeting our assumption, may not be inherently simpler to recover without considering specific procedure to handle Gaussian sources.\nIn addition, as expected, the performance of SparseICA improves in terms of both MCC and Amari distance as the sample size increases.\nDifferent ratios of Gaussian sources.

The empirical results of MCC based on  samples are depicted in Figure 1  ###reference_###, while those of Amari distance are provided in Figure 4  ###reference_### in Appendix G  ###reference_###. One observes that the identification performance SparseICA is rather stable across different ratios of Gaussian sources, which may not be surprising as it leverages only second-order statistics. On the other hand, the performance of FastICA-D and FastICA deteriorates as the ratio of Gaussian sources increases, because it relies on non-Gaussianity of the sources. It is also observed that, in the presence of Gaussian sources, FastICA-D and FastICA may perform well, provided that the ratio (or number) of Gaussian sources is not large. This suggests a potential future direction to integrate our method based on second-order statistics with existing methods that rely on non-Gaussianity, which may better handle both Gaussian and non-Gaussian sources.\n###figure_4### ###figure_5### ###figure_6###"

Before proving Proposition 10  ###reference_position10###, we state the following lemma from Shimizu et al. [41  ###reference_b41###] that is useful for the proof.\nLet  be a lower triangular matrix with all diagonal entries being nonzero. Let  and  be two permutation matrices. Then, a permutation of rows and columns of , i.e., , has only nonzero entries in the diagonal if and only if the row and column permutations are equal, i.e., .\nWe now provide the proof of Proposition 10  ###reference_position10###.\nSuppose  for matrices , , and . Then,\n satisfies Assumption 2  ###reference_umption2### if and only if matrix  represents a DAG.\nWithout loss of generality, we consider the case in which  and  differ only in column permutations, instead of signed column permutations. This is because, for the latter case, there exists a diagonal matrix  with diagonal entries being  such that  and  differ only in column permutations, and furthermore,  satisfies Assumption 2  ###reference_umption2### if and only if  satisfies Assumption 2  ###reference_umption2###.\nTherefore, suppose there exists a permutation matrix  such that\nWe now consider both parts of the statements.\nIf part:\nSuppose that matrix  represents a DAG. Then, there exists permutation matrix  such that  is strictly lower triangular. Therefore,  is lower triangular. This implies that  is lower triangular because  is a diagonal matrix and does not affect the support. By substituting Eq. (26  ###reference_###),  is lower triangular. Clearly,  is also a permutation matrix. Therefore, matrix  can be permuted by row and column permutations to be lower triangular, and thus satisfies Assumption 2  ###reference_umption2###.\nOnly if part:\nSuppose matrix  satisfies Assumption 2  ###reference_umption2###. Then, there exist permutation matrices  and  such that  is lower triangular. Substituting Eq. (26  ###reference_###),  is lower triangular.

Applying Lemma 11  ###reference_ma11### w.r.t. matrix , we have\nwhich, by plugging into Eq.

Since right multiplication of  does not affect the support of , we see that\nis also lower triangular. This indicates that  is lower triangular, which, with the assumption that the diagonal entries of  are zeros, imply that  is strictly lower triangular. Therefore, matrix  represents a DAG.\nAfter proving Proposition 10  ###reference_position10###, we now consider Proposition 11  ###reference_position11###. Before that, we provide a result by Ghassami et al. [21  ###reference_b21###] that is useful for the proof. We first describe the notion of parent exchange by Ghassami et al. [21  ###reference_b21###]. Let  be the symmetric difference operator that identifies the elements present in either of the sets but not in the intersection. For DAG  with weighted adjacency matrix , its vertices  and  are said to be parent exchangeable if , i.e., there exists  such that . In such case, a support rotation can be performed on columns  and  that sets a nonzero entry on those columns, except  and , to zero. In other words, the parent of  and  that corresponds to the zeroed entry is removed. Furthermore, the entry  or  is set to , which corresponds to adding the missing edge  or . Ghassami et al. [21  ###reference_b21###] defined such an operation to be a parent exchange. We then provide the following corollary that is straightforwardly derived from Ghassami et al. [21  ###reference_b21###, Corollary 2 & Proposition 1].\nDAGs  and  are Markov equivalent if and only if there exists a sequence of parent exchanges that maps  to , and one that maps  to .\nWe now provide the proof of Proposition 11  ###reference_position11###.\nLet  be a DAG with weighted adjacency matrix . Then, matrix  satisfies Assumption 1  ###reference_umption1### if and only if the Markov equivalence class of  is a singleton.\nWe consider both parts of the statements.\nIf part:\nWe provide a proof by contrapositive. Suppose that matrix  does not satisfy Assumption 2  ###reference_umption2###. That is, there exist  and  such that\nClearly, we have , because otherwise there will be a cycle with length of two over variables  and , which contradicts the assumption that  is a acyclic. This implies\nBy definition,  and  are parent exchangeable, and therefore there exists a parent exchange that maps DAG  to another directed graph  where . We now show by contradiction that  is a DAG. Suppose that  is a not DAG. By Eq. (28  ###reference_###), there exists variable  such that\nHere, we must have  or , because otherwise we have\nwhich leads to a cycle over variables  and . Without loss of generality, we consider the case of , which implies\nand . This indicates that the entry  is set to  (i.e., the edge  is added) after the parent exchange to DAG , which subsequently leads to a cycle in . In this case, there must exist a path  in DAG , where  and , to which adding the edge  leads to a cycle in DAG . By Eq. (29  ###reference_###),  is also a parent of , indicating that there exists a cycle  in DAG , which contradicts the assumption that  is acyclic. Therefore,  must be a DAG.\nSince there exists a parent exchange that maps DAG  to another DAG , clearly there also exists a (reversed) parent exchange that maps DAG  back to DAG . By Corollary 2  ###reference_ollary2###, DAGs  and  are Markov equivalent. Therefore, the Markov equivalence class of  contains at least two DAGs and is not a singleton.\nOnly if part:\nSuppose that matrix  satisfies Assumption 2  ###reference_umption2###. That is, for all  and ,we have\nIn this case, every pair of vertices are not parent exchangeable, and thus parent exchange cannot be applied for any pair of vertices in DAG . Therefore, for any DAG , there exists no sequence of parent exchanges that maps  to , implying that they are not Markov equivalent. This indicates that all DAGs are not Markov equivalent to DAG , except itself, and thus the Markov equivalence class of  is a singleton.\nWith Propositions 10  ###reference_position10### and 11  ###reference_position11### in place, we provide the proof of Theorem 5  ###reference_orem5###.\nSee 5  ###reference_orem5###\nWe consider both parts of the statements.\nIf part:\nSuppose matrix  represents a DAG whose Markov equivalence class is a singleton.

By Proposition 11  ###reference_position11###, the Markov equivalence class of the DAG represented by  is a singleton.\nBefore proving Lemma 1  ###reference_ma1###, we first provide another result that is useful for the proof.

Also, it is known that the weighted adjacency matrix of a directed graph can be permuted via simultaneous equal\nrow and column permutations to be strictly lower triangular if and only if the graph is a DAG. Therefore, we provide the following corollary that is straightforwardly implied by the results by Zheng et al. [54  ###reference_b54###], Wei et al.

At the core of one of the most important approaches to the AI revolution are machine learning (ML) algorithms: computer programs that improve performance as they are exposed to an increasing amount of data. An example of disruptive technology based on ML is AlphaFold \u2013 an AI algorithm developed by Google\u2019s offshoot DeepMind first released in 2018, which solved one of the most challenging problems in the field of biology: the prediction of protein\u2019s structures based on amino-acid sequences \\parencitejumperHighlyAccurateProtein2021, callawayItWillChange2020. A more recent example is ChatGPT, a Large Language Model (LLM) developed by OpenAI. It is based on the GPT (Generative Pre-training Transformer) architecture and is trained to generate human-like text. ChatGPT and other LLMs available in the early 2020s have been identified as having impact in diverse areas that go from medicine \\parencitejeblickChatGPTMakesMedicine2022 to journalism \\parencitepavlikCollaboratingChatGPTConsidering2023 and their impact on science is heavily discussed \\parencitestokel-walker_what_2023.\nThese breakthroughs and many others are underpinned by developments in Deep Learning (DL), a subset of ML models that relies on neural networks and requires vast amounts of data to be trained \\parencitelecunDeepLearning2015. Due to the extremely promising results in wide areas of application, DL has been regarded as a new method of invention and potentially a general-purpose technology in which the next industrial revolution maybe based \\parencitecraftsArtificialIntelligenceGeneralpurpose2021. Although a growing literature has studied the impact of DL on the knowledge production process \\parencitebianchiniArtificialIntelligenceScience2022, klingerDeepLearningDeep2021, little attention has been given to its inception and to the specific role played by Open Labelled Datasets (OLDs).\nIn this paper we analyze the emergence of DL as a technoscientific field, that is, a domain in the middle of scientific enquiry and technical problem-solving \\parencitekastenhoferCommunityIdentityContemporary2021. More specifically, we examine how OLDs have contributed to the growth and consolidation of DL, focusing on their distinct characteristics. Within this perspective, we regard OLDs as technological artifacts that allow the development of the field. We draw on the literature discussing the emergence of new scientific disciplines to provide a picture of the development of DL as the dominant approach in ML & AI, and the role of OLDs in that process. We perform an analysis of the technological and scientific use of OLDs that includes both qualitative and quantitative elements. We devote particular attention to the role played by CIFAR-10, the most used dataset in the ML literature indexed at the Papers with Code website111See Section 4.2  ###reference_### for details.. We carried out a set of semi-structured interviews with relevant actors and we implemented a survey of academics and ML practitioners who have used CIFAR-10 in their work; on the basis of the qualitative evidence we modeled the use OLDs in technological and scientific development proxied by patent (technology) and scholarly (science) citations in the period 2000-2022.\nCompute, data and algorithmic advances are the needed ingredients of the DL revolution \\parenciteKochPeterson2024, Sevilla2022. In early 2010s increased computing power availability (see the arrival of 2D and 3D GPUs) was in line with the doubling approximately every 6 months of computing requirements by new DL algorithms running on OLDs \\parenciteSevilla2022. The main tenet of this paper is that once the bottleneck of computer power was not any longer a major problem, the potential of neural network approaches to AI - theoretically developed over the last fifty years of the 20th century - could be realized and further advanced through the use of OLDs. Given that AI as a field shifted towards an evaluation system based on benchmarking - quantification of progress based on predictive accuracy on example datasets \\parenciteKochPeterson2024, OLDs became fundamental to develop better algorithms/architectures. Models (algorithms and architectures) were developed to solve specific tasks using specific OLDs; they would not exist without the dataset, as the specific OLD allowed the development of more refined and accurate models. OLDs that required less computing power, such as CIFAR-10, a small-but-sufficiently-large dataset, enabled the testing and refinement of new model architectures like AlexNet, which succeeded in solving tasks using huge and complex datasets that were previously unattainable with the same computational resources. OLDs should be considered as the necessary testing tool that had to be developed to allow progress in the DL modelling.\nThe qualitative evidence we put together support the view that OLDs, and CIFAR-10 in particular, were fundamental for the technological and scientific developments which lead to the DL revolution and still shape the trajectory of the field. We trace the creation of the CIFAR-10 to the CIFAR NCAP Summer School in 2008, where the labelling of the dataset was conducted mostly by graduate students over the supervision of Geoffrey Hinton, a prominent scholar in the field, and two of his students, Alex Krizhevsky and Vinod Nair. We also learned through our interviews that CIFAR-10 became a benchmark due to its technical specifications, namely the nature of the images, their size, the number of samples and categories. The survey confirms the insights of the interviews and highlights that CIFAR-10 is used extensively in the training of computer scientists working with ML. Many researchers not only teach courses using CIFAR-10, but also were themselves exposed to the dataset while following graduate programs. This finding highlight teaching as an important channel through which CIFAR-10 impacted the field of DL.\nBy examining data from 28,393 conference proceedings and journal publications in the ML literature that utilized OLDs to train models between 2010 and 2022, we assess the technological and scientific relevance of these papers based on their citations in patents and academic literature. Our econometric analysis confirms the significant role of CIFAR-10 in the technological and scientific development of DL. Specifically, we find that papers using CIFAR-10 \u2014 a small but sufficiently large dataset \u2014 had a substantial early impact on the scientific literature, as evidenced by high academic citation counts, and continue to be relevant today, as shown by their higher patent citation counts. This indicates that the technical characteristics that initially contributed to the dataset\u2019s success continue to drive research and technological advancements in DL, particularly in computer vision and image recognition. We compared the CIFAR-10 and ImageNet datasets, demonstrating that CIFAR-10 has been and continues to be significant for technological developments, while ImageNet keep on playing a prominent role in scientific developments within the DL literature.\nThe rest of the paper proceeds as follows. In the next section, we present the conceptual framework used followed by the historical and institutional background of DL research and OLDs in Section 3. Section 4 describes the empirical methodology, data collection, the construction of the sample and presents descriptive statistics. Section 5 reports and discusses the results of the analysis. Section 6 concludes the paper."

The most important idea presented by Kuhn is how scientific knowledge does not always grow in a stable and incremental fashion, but it can also go through short periods of big changes, in which new paradigms emerge and consolidate.\nIn this paper we explore in particular the question of how OLDs contributed to the process of making DL into the dominant paradigm within AI \\parencitekerstingMachineLearningArtificial2018, chahDeepRabbitHole2019, schmidhuberDeepLearningNeural2015, after being dismissed for a long time in favor of symbolic AI \\parencitewaldropWhatAreLimits2019, weberRiseDatadrivenAI2021. To do so, we mostly rely the theoretical contributions of \\textcitefrickelGeneralTheoryScientific2005. They argued that there are parallelisms between social movements and what they call Scientific/Intellectual Movements (SIMs). Just as social movements, SIMs involve the pursue of common projects and objectives by a group of people that must rely upon repertoires of collective action to face the resistance from others in the scientific or intellectual community. Since SIMs resemble social movements that emerge to challenge some previous paradigm and therefore inevitably face some level of resistance, they also must deal with the problems of collective action: \"The emergence of new social forms in science and academe invariably requires some level of spatial, temporal, and social coordination.\" \\parencitefrickelGeneralTheoryScientific2005.\nFollowing \\textcitekuhnStructureScientificRevolutions1970, we also consider that SIMs emerge at times of scientific crisis, when research anomalies linked to old paradigms have accumulated beyond a tolerable threshold. However, the contempt towards the dominant paradigm is only a prerequisite and never enough to generate a SIM. For an intellectual movement of that sort to be successful, the leaders must articulate a a distinctive research program program. Doing so requires certain structural conditions, especially the access to resources, such as employments for the members of the SIM, access to laboratories, academic positions that allow to publish their results, and organizational resources that allow the members of the SIM to come together and create epistemic cultures, and discuss repertoires of thought and action that allow them to advance their intellectual agenda.\nAfter the initial conditions are given, SIMs also have the need (like social movements) to recruit new members, to do so a locus of exchange and discussion where novel research is presented to old members and potential new recruits become a major condition for the success of the movement. This scenarios of micromobilization can take the form of seminars, conferences, PhD positions, or summer schools. SIM must find ways to validate itself both internally, building a narrative of its history and identity, and externally, against opponents \\parencitefrickelGeneralTheoryScientific2005.\nIn the case in hand, in the 80s and 90s, there was a group of scientists, in different universities around the United States, Europe and Canada who were not satisfied with the direction of the research programs in AI, based mostly on symbolic systems. Among them, Geoffrey Hinton, a University of Toronto professor, who was convinced that DL \"had to be the future of AI\" \\parencitegoldman10YearsLater2022. He and some of his colleagues \u2013 particularly Yan LeCun and Yoshua Bengio \u2013 were at the forefront of the DL revolution. \\textcitewaldropWhatAreLimits2019 describes what happens during this contentious period of the 80s and early 90s:\nToday\u2019s deep-learning revolution has its roots in the \"brain wars\" of the 1980s when advocates of two different approaches to AI were talking right past each other. On one side was an approach\u2014now called \"good old-fashioned AI\"\u2014that had dominated the field since the 1950s. Also known as symbolic AI, it used mathematical symbols to represent objects and the relationship between objects. [\u2026] But by the 1980s, it was also becoming clear that symbolic AI was impressively bad at dealing with the fluidity of symbols, concepts, and reasoning in real life. In response to these shortcomings, rebel researchers began advocating for artificial neural networks, or connectionist AI, the precursors of today\u2019s deep-learning systems \\parencite[p. 1075]waldropWhatAreLimits2019.\nThe Canadian Institute of Advanced Research (CIFAR), a research funding organization based in Toronto that finances basic research with a high-risk, high-reward philosophy was, since its foundation in the 1980s, consistently interested in the advancement of AI and was at the forefront of the upsurge of ML technologies \\parencitechahDeepRabbitHole2019. CIFAR became the institutional setting on which those \"rebel researchers\" were able to join forces and form their own epistemic culture. CIFAR provided access to symbolic resources in the form of positions - like fellowships - for some of them, but also material resources in the form of funding (not in a significant amount) for conferences, meetings and summer schools, all of them part of the micromobilization scenarios needed to recruit new members, discuss novel ideas, and in general advance their agenda."

David elaborated on the concept of open science contrasting it with the increasing reliance on Intellectual Property Rights (IPRs) in the production of science \\parencitedavidEconomicLogicOpen2003, davidCanOpenScience2004, davidDigitalTechnologyBoomerang2005. Open science in its original conception, takes a descriptive sense, referring to a new paradigm born:\nwith Renaissance mathematics, the cultural ethos and social organization of western European scientific activities during the late sixteenth and seventeenth centuries [\u2026] \u2013departing from the previously dominant regime of secrecy in the pursuit of \u2018Nature\u2019s secrets\u2019 \\parencite[p. 15]fadfc20e-20f4-3bc9-8e9f-d067328c5712.\nThis new paradigm shaped the organization of the scientific endeavor in the West, including the imperatives of public disclosure of discoveries, and the methods that lead to those discoveries. This openness was supported by a public (open) system of Universities and research communities, and a series of norms, including communalism, universalism, desinterestedness, originality and skepticism \\parencitemertonSociologyScienceTheoretical1973, that created a reward system based on collegiate reputation that was achieved by validated claims to priority in discovery or invention \\parencitedavidEconomicLogicOpen2003.\nSince its inception, the concept positions itself as opposed to a \"closed\" science based on IPRs like patents and copyrigts, that jeopardize the traditional ethos of open science. Scholars like Dasgupta & David \\parenciteparthaNewEconomicsScience1994, davidCanOpenScience2004 have warned about the social and economic problems that might arise from the enclosure of scientific knowledge within the framework of IPRs. Among others potential hazards, they mention a suboptimal level of production of basic science, which have the greatest spillovers; and scientists getting more and more engaged in duplicitous work, unable to access a big part of the stock of codified knowledge in the form of patents created by a culture of \"intellectual capitalism\" \\parencitedavidCanOpenScience2004.\nMore recently, the advent of the digital technologies, and in particular the internet, has given rise to a slightly different conceptualization of open science that lies \"between the age-old tradition of openness in science and the tools of information and communications technologies (ICTs) that have reshaped the scientific enterprise\" \\parenciteoecdMakingOpenScience2015. In this conception, open science is (loosely) defined as \"efforts by researchers, governments, research funding agencies or the scientific community itself to make the primary outputs of publicly funded research results \u2013 publications and the research data \u2013 publicly accessible in digital format with no or minimal restriction as a means for accelerating research; these efforts are in the interest of enhancing transparency and collaboration, and fostering innovation\" \\parenciteoecdMakingOpenScience2015. In this conception, open science is part of an \u2018open ecosystem\u2019 that encompasses open access journals, open data, open software, open collaboration, open peer review, among others.\nOne element of the open science ecosystem is particularly relevant for this work is open data. The European Commission provides a definition, stating that \"Open Data is data that is made available by (public) organisations, businesses and individuals for anyone to access, use and share\" \\parenciteeuropeancommissionAIOpenData2018. Access to data can have many advantages or purposes. Data (for example from public records) can be used for original research; for reproducing and validating (or not) existing knowledge; or to explore new research avenues.\nCertainly data has become relevant for many areas of scientific inquiry; but for DL in particular, data is a conditio sine qua non for its very existence, since the neural networks on which it is built rely on the availability of large amounts of data. Open data, built collaboratively, clearly labeled and free to access on the Internet was key to the emergence and eventual dominance of DL within AI \\parencitemartensImpactDataAccess2018."

Although the theoretical basis for AI, based on ML algorithms and convolutional neural networks, was established in the 1980s, the first significant bottleneck from the 1990s onwards was the availability of large amounts of training data necessary to \"feed\" the DL models.\nBesides the availability of training data, the development of DL depended also on the increase of computing power. Because of the enormous amounts of data to be processed and the increasing complexity of the algorithms used to analyze that data, computing capacity became a bottleneck for the development of DL until the second decade of the twenty-first century. Despite the excitement with neural networks in the 80s and 90s \"computers were not powerful enough to allow this approach to work on anything but small, almost toy-sized problems\" \\parencitedeanDeepLearningRevolution2020.\nThe paradigm of general-purpose computing on GPU cards, originally used for gaming, \"because of GPU cards\u2019 high floating point performance relative to CPUs, started to allow neural networks to show interesting results on difficult problems of real consequence.\" \\parencitedeanDeepLearningRevolution2020. In particular, from mid 90s the performance of GPUs increase significantly with 2D and 3D acceleration on the same unit. The coming on the market of Nvidia GeForce 256 in 1999 is usually considered the turning point of the industry. The consequence of those technological advances was that \"computers finally started to become powerful enough to train large neural networks on realistic, real-world problems\" \\parencitedeanDeepLearningRevolution2020.\nBy 2009 when CIFAR-10 was launched, the technological conditions for its use and exploitation were mature. CIFAR-10 became a dataset that could be manipulated on personal computers (see Table 1  ###reference_### below for a comparison of computing requirements of mostly used OLDs), and used as a toy-dataset to train and improve algorithms that could later be used on more complex datasets such as ImageNet."

Different from pure sciences, the quest of technoscience is not only motivated by a search for new knowledge in an abstract way, but to the solution of practical problems. In fact, \"technoscience is \u2018face to face\u2019 with the things. It is less interested in what they are or what regular behaviors they are naturally disposed to exhibit, and more interested in what they can become or what they might offer\" \\parencitebensaude-vincentMattersInterestObjects2011. Usually, in the policy arena, technosciences are often referred to as Pasteur Sciences \\parencitestokes_pasteurs_2011.\nIn the case of DL, the practical applications go from medical image analysis, language translation, object detection for autonomous vehicles, content filter, and many others \\parencite[Cfr.][]bengioDeepLearningAI2021. It is no surprise then that technosciences develop strong links with industry, as shown by the fact that most of the academics that ignited the DL revolution ended up joining the industry (Geoffrey Hinton in Google; Yan LeCun in Facebook, and Yoshua Bengio in his own venture, Element AI).\nThe theoretical implications of considering AI as a technoscience and DL as a paradigm within it, mean a deviation from a traditional analysis of a scientific discipline. For example, even if traditional criteria, like the priority of discovery \\parencitemertonPrioritiesScientificDiscovery1957 still apply, it does in a different way. More than publications in academic journals, breakthroughs are shown through competitions, in which the new techniques (in this case the algorithms) are tested against a certain benchmark to validate the real-world performance of the discovery. In other words, the understanding of causal mechanisms in the aim of proving or disproving a certain theoretical perspective become secondary, while practical (technological) results are of the utmost importance.\nThis is very clear in the case of DL. \\textcitebengioDeepLearningAI2021 highlight that \"DL scored a dramatic victory in the 2012 ImageNet competition, almost halving the error rate for recognizing a thousand different classes of object in natural images\". Other authors like \\textcitelecunDeepLearning2015 and \\textciteschmidhuberDeepLearningNeural2015, also underscore the performance of the algorithms in those competitions as the most important milestones in the paradigm shift. 2012 became to be know as the year of the \"DL revolution\" The practical performance becomes then more relevant than the actual understanding of the mechanism that drive those results. In fact, \"once a DL system has been trained, it\u2019s not always clear how it\u2019s making its decisions\" \\parencitewaldropWhatAreLimits2019. Articles in scientific journals play a role in the development of this new technoscience but other forms of knowledge diffusion and creation of reputation such as conference presentations, conference proceedings and patents are of similar or higher importance \\parencitefranceschet_role_2010, meyer_viewpointresearch_2009, fortnow_viewpointtime_2009. For example, in the full sample of 37,242 articles identified in this paper as composing the relevant literature in DL for computer vision and image recognition around 55% were conference proceedings. Science and technology are interlinked and publications and proceedings are cited more frequently and faster in patents protecting downstream technological development. To try to capture developments in the field we must therefore use both patents and publications because the latter would only provide a limited representation of the evolution of the science."

It involves training artificial neural networks, which are composed of layers of interconnected nodes or \"neurons\" to learn from large amounts of data. These networks can be used to perform a wide variety of tasks, such as image and speech recognition, natural language processing, and decision making. DL is often used in combination with other techniques, such as reinforcement learning, to solve complex problems \\parencitelecunDeepLearning2015.\nDL is a subset of ML, which in turn is defined as \"concerned with the question of how to construct computer programs that automatically improve with experience\" \\parencitemitchellMachineLearning1997. ML, on the other hand, is one of the most important approaches of AI.\nAI, ML and DL are interrelated but differ from each other. \\textcitechahDeepRabbitHole2019 makes the following distinction:\nAlthough the three terms \u2014AI, ML and DL\u2014 are intricately linked, nuanced differences in their specific definitions can make the difference between whether the term is used precisely or whether the actual operations on the ground are obfuscated. The dynamic definition of AI affects what state-of-the-art advances are considered as AI for a particular time and place. ML is primarily concerned with training machines to learn from data, following closely the original definition by Arthur Samuel in 1959. To implement the ever-changing state-of-the-art techniques that exhibit AI capabilities, DL is one of the most popular sets of ML techniques in use today \\textcite[p. 3]chahDeepRabbitHole2019.\nThe concept of DL was coined in 2006 by Geoffrey Hinton and his colleagues \\parencitelecunDeepLearning2015, chahDeepRabbitHole2019. However, the concepts on which this technology is based, started to develop long before with the work on artificial neural networks in the 1940s \\parenciteschmidhuberDeepLearningNeural2015, chahDeepRabbitHole2019 that evolved in the 1980s into the covolutional neural network \\parencitefukushima_neocognitron_1980.\nDespite being a growing field, DL was at the peripheries of AI for many decades. According to Yan LeCun, one of the main proponents and intellectual architects of the DL revolution \"In the late 1990s, neural nets and backpropagation were largely forsaken by the machine-learning community and ignored by the computer-vision and speech-recognition communities\" \\parencitelecunDeepLearning2015. By 2006, a paper by \\textcitehintonFastLearningAlgorithm2006 reignited the interest, by showing the possibility of using DL to achieve state-of-the-art results (1.25 percent error rate) in recognizing handwritten digits. In 2012, a DL algorithm developed by \\textcitekrizhevskyImageNetClassificationDeep2017 won the ImageNet classification competition, one of the most challenging image recognition databases at the time. AlexNet, the winning algorithm, became a milestone that positioned DL as the dominant paradigm within ML and consequently within AI.\nAlexNet was developed by Alex Krizhevsky in collaboration with Ilya Sutskever and Geoffrey Hinton. Both Krizhevsky and Hinton were also behind the creation of CIFAR-10, which became the basis for the development of the AlexNet algorithm (Fergus, 2022, Interview No. 2; Bengio, 2022, Interview No. 5)."

In 2004, CIFAR supported a diverse group of unorthodox scientists led by Geoffrey Hinton into pursuing an ambitious program in AI called Neural Computation and Adaptive Perception Program (NCAP) (Silverman, 2022, Interview No. 7; [brownellHowArtificialIntelligence2016a]).\nOn his account of the beginning of the NCAP program, Prof. Silverman highlights how this group of people were full of new ideas, but did not have the institutional spaces to present and discuss them:\nBut when I\u2019m trying to create a scenario, where, as they spoke, [\u2026] that they sort of, had come together as a group, informally because they didn\u2019t have anybody to talk to in their own departments. There they were, they had their own disciplines, they made it into, they had faculty appointments, they were achieving in their own departments, but basically, their interests had taken them in a much broader, different way [to] understand how the brain processes information, not really staying in a single lane, if you know what I mean.

(Silverman, 2022, Interview No. 7).\nCIFAR became then the institutional space that provided with basic resources for that group of people to come together and start exploring their common interests. Geoffrey Hinton was joined in his research effort by Yoshua Bengio, and Yann LeCun. Their work became a seminal piece in the paradigm shift that saw DL become the dominant approach in AI. \"Their work together led to a number of advances, including a breakthrough AI technique called DL, which is now integral to computer vision, speech recognition, natural language processing, and robotics\" \\parencitefarrowTuringAwardHonours2019. Because of this work, they received the A.M. Turing Award, considered as the \"Nobel Prize of Computing\".\nOpen Labeled Datasets.\nBefore 2009, the two main datasets used for computer vision and object recognition tasks were CALTECH-101 and MNIST (Modified National Institute of Standards and Technology database). CALTECH-101 is a dataset that contains pictures of objects belonging to 101 categories. It contains about 40 to 800 images per category, with most categories containing about 50 images. It was collected in September 2003 by Fei-Fei Li, Marco Andreetto, and Marc\u2019Aurelio Ranzato \\parenciteli_andreeto_ranzato_perona_2022. MNIST was one of the first annotated datasets used in ML models and consists of large collection of images of handwritten digits taken from the CENSUS bureau, it contains 60,000 black and white training images and 10,000 testing images, it was released by AT&T Bell Labs in 1998 \\parenciteGoltsev2004. The CIFAR team worked mostly with MNIST.\nIn 2006, Rob Fergus, Antonio Torralba and William T. Freeman released the \"80 million tiny images\", a new dataset that could overcome some of the limitations of the existing ones. They automatically collected low-resolution images from different search engines (Altavista, Ask, Flickr, Cydral, Google, Picsearch and Webshot) and loosely labeled with one of the 53,464 non-abstract nouns in English, as listed in the Wordnet lexical database \\parencitetorralba80MillionTiny2008. However, in the original paper in which he introduces the CIFAR databases, \\textcitekrizhevsky2009learning mentions that he is trying to solve\nA [\u2026] problematic aspect of the tiny images dataset is that there are no reliable class labels which makes it hard to use for object recognition experiments. We created two sets of reliable labels. [\u2026]. Using these labels, we show that object recognition is significantly improved by pre-training a layer of features on a large set of unlabeled tiny images. \\parencite[p. 1]krizhevsky2009learning\nIn 2008, Geoffrey Hinton, along with two of his students, Vinod Nair and Alex Krizhevsky, had the idea to manually label a sub-set of the \"80 million tiny images\" (Fergus, 2022, Interview No. 2), to address one of the problems they encounter when using this large dataset for unsupervised training. To label the images, they took advantage of the NCAP Summer School that took place in August 2008. The students that participated occupied some of the time labeling the images according to a protocol written by Alex Krizhevsky and Rob Fergus (Fergus, 2022, Interview No. 2). Rob Fergus account of the process is that\nthe data [From the 80 million tiny images] need[ed] to be manually cleaned in order to make a sort of good supervised training dataset. And Geoff wants you to do this. And so he organized the CIFAR summer school, he got all the summer school students sitting down. So how did it work? So I think Alex Krizhevsky and I wrote a labelling routine to actually, you know, have labelling interface where all the students would sit down, and we will go through the images, cleaning them up, and we decided that, Geoff decided he was going to pick, you know, these 10 Super categories, and then each one of which had subcategories that form the CIFAR 100. (Fergus, 2022, Interview No. 2).\nIn that way, the CIFAR team created the CIFAR-10 dataset, which consists of 60,000 32x32 color images in 10 classes, with 6,000 images per class; and the CIFAR-100 is just like the CIFAR-10, except it has 100 classes containing 600 images each. The datasets overcame some of the problems encountered in older open datasets, while keeping an architecture similar to that of MNIST. These two datasets were subsequently used to train computer vision algorithms through a procedure called supervised learning. \\textcitelecunDeepLearning2015 explain supervised learning as follows:\nImagine that we want to build a system that can classify images as containing, say, a house, a car, a person or a pet. We first collect a large data set of images of houses, cars, people and pets, each labeled with its category. During training, the machine is shown an image and produces an output in the form of a vector of scores, one for each category. We want the desired category to have the highest score of all categories, but this is unlikely to happen before training. We compute an objective function that measures the error (or distance) between the output scores and the desired pattern of scores. The machine then modifies its internal adjustable parameters to reduce this error. These adjustable parameters, often called weights, are real numbers that can be seen as \u2018knobs\u2019 that define the input\u2013output function of the machine. In a typical deep-learning system, there may be hundreds of millions of these adjustable weights, and hundreds of millions of labeled examples with which to train the machine \\parencite[p. 436]lecunDeepLearning2015.\nIt is clear from this definition that supervised learning requires vast amounts of data and very well labeled, so that the machine can be trained with this clean set of images and thus learn how to recognize objects of the same classes. By 2009, there were not datasets the combined a large number of images, a rigorous labelling process, and well constructed categories that made it easy to manipulate. CIFAR-10 and CIFAR-100 became quickly benchmarks for new algorithms of computer vision using DL. However, it was CIFAR-10 that had the most impact. According to experts\u2019 accounts [Fergus, 2022, Interview No. 2] beyond the reliability, the size of this dataset and its simplicity were key for its success. In fact, it was light enough so that it was easy to manipulate and work with, specially to train algorithms that require a lot of computer power, but had enough data to properly train a neural network. As a corollary, Fergus (2022, Interview No. 2) added that the fact that \"every student can run CIFAR-10 on their laptop\" make a difference in terms of usage.\nCIFAR databases were made available for free on the web from the University of Toronto, very much in line with the Open Data paradigm mentioned above. Along with the other characteristics, the easy availability became one the distinctive characteristics and main advantages of the CIFAR datasets.\nDuring the same period, other research teams were developing similar image databases. One notable example is ImageNet, created by Fei-Fei Li (currently at Stanford University, formerly at the University of Illinois Urbana-Champaign) and Christiane Fellbaum (Princeton University), and introduced in 2009. ImageNet includes a large collection of labeled object images and rapidly became a benchmark for state-of-the-art computer vision algorithms. The dataset was annotated using Amazon Mechanical Turk (MTurk)222MTurk is a crowdsourcing platform provided by Amazon Web Services that connects businesses and researchers with a global pool of remote workers. It is designed to handle tasks that are difficult for machines but relatively easy for humans, such as labeling datasets.. For a more detailed description of ImageNet and other similar datasets, see Section 4.2  ###reference_### and Table C1  ###reference_###.\nIn the following sections, we will evaluate whether OLDs, particularly CIFAR-10, have influenced the development and evolution of DL as a technoscience. Specifically, we will explore whether the unique characteristics of these open datasets contributed to the development of the foundational Convolutional Neural Network (CNN) architectures that sparked the DL revolution."

The initial step was to conduct semi-structured interviews with relevant actors, including prominent academics working on the field of AI and DL, as well as CIFAR personnel linked directly or indirectly to the creation of CIFAR-10. Two kinds of interviews were conducted: general interviews with academics working on AI, not necessarily related to CIFAR datasets, with the aim of getting an understanding of the field and some general features that practitioners might look for in a training dataset; and more specific interviews with strategic individuals that were directly or indirectly related to the development of the CIFAR datasets. In total we conducted 7 interviews, out of which 2 were with field experts not linked to CIFAR; and 5 with persons linked to CIFAR.\nSecond, we surveyed researchers and practitioners who referred to CIFAR datasets in their articles. The survey aims to validate the information obtained from the interviews and develop a broader assessment of the impact of the CIFAR-10 on DL and Computer Vision. The sample population includes corresponding author from the subset of papers referencing CIFAR datasets out of 6,060 paper we were able to retrieved 3,033 valid emails (see Qualitative Methodology Appendix A  ###reference_### for the response analysis and survey questions). We were able to collect 295 answers to the survey, which corresponds to a response rate of 9.4%. The response analysis indicates that our sample is representative for most variables available for the population (total and valid email).\nFinally, we concentrated on publications in the ML literature that utilized OLDs for model training between 2010 and 2022, following the release of the CIFAR and ImageNet datasets. We conducted an econometric analysis aimed at examining the relationship between the use of specific OLDs and receiving citations from patent and scientific publications. Our method involved comparing publications that referenced CIFAR-10 and ImageNet with those that did not but used one of the other similar labeled datasets, while controlling for various confounding factors. Specifically, we estimate regressions of the following models:\nFor each focal paper published of type  (scholarly journal or conference proceeding), in a scientific area  and year , we measure its outcome using different metrics that capture their technological and scientific citation impact. Our main explanatory variables are binary indicator s that assumes value 1 if the paper mentioned only CIFAR-10, CIFAR-10 and other datasets or ImageNet. Our main dependent variables which we use as measure of technological and scientific relevancy are the total number of patents citing the articles and the total number of scientific citations.\nTo ensure a fair comparison of our articles, we develop an empirical design that allows us to compare similar ML/DL articles that differ only in their use of the CIFAR-10 dataset for model training. Thus, we incorporate a set of control variables, , which describe various characteristics of the focal papers and are related to citation impact. These controls include the number of authors, the number of references, the presence of international collaboration, and the share of authors affiliated with companies, as these factors may influence both the use of CIFAR-10/ImageNet and citation impact.\nAdditionally, we include as control variables observable characteristics of the labeled datasets used in the papers, such as the number of OLDs mentioned, the number of modalities (i.e., different types of data beyond images, such as text and audio), and the number of ML prediction tasks performed with these datasets333Further considerations regarding tasks are provided in Section 4.2  ###reference_###. As the field advances, datasets are increasingly applied to new tasks. Nonetheless, we use the number of unique tasks identified for each dataset up to July 2023 as a proxy for the breadth of application of a specific OLD in these fields.. These dataset characteristics serve as proxies for the types of DL models being developed and refined, helping us partially control for factors that could simultaneously affect both citation counts and the use of the primary OLDs under investigation.\nWe then estimate a fixed-effects Poisson model, including the independent and control variables discussed above and a set of fixed effects which includes type of publication , scientific fields  and calendar year  to control for time-invariant features that may also explain citation impact. In the robustness checks we use Negative Binomial model and different variable operationalization and sample definitions to test the consistence with. We use the same setting for both technology and scientific citations impacts.\nWe do a split sample analysis focusing on two periods 2010-2014 and 2015-2022. We identify 2014 a year of structural change in the motivations to use CIFAR-10 because it was the year where state-of-the-art DL models consistently surpassed human-level accuracy in image classification tasks444The human error rate on CIFAR-10 is estimated to be around 6%. Working papers originally published in the end of 2014 achieved an error rate of around 3-4% \\parencitegraham_fractional_2015.. Thus, from 2015 onward CIFAR-10 was essentially a \"solved problem\": prediction accuracy and error rates of trained models were comparable to humans-levels. We perform the split sample analysis for both model 1  ###reference_### and 2  ###reference_###: while the former allow us to estimate how many citations papers using CIFAR-10 are expected to receive compared to papers that do not (conditional on observable paper characteristics), the latter model enables us to assess the expected citations for papers using CIFAR-10 or ImageNet in comparison to others. By comparing the coefficients of the CIFAR-10 and ImageNet variables, we can evaluate how papers utilizing datasets of different dimensions and complexity perform in terms of citations."

These tasks refer to different types of predictions or inferences made using models trained on specific data. For example, image datasets can be used to train ML models to solve tasks such as image classification, object detection, and anomaly detection.

We acknowledge that this approach has limitations, as authors might not always mention the dataset used to train their models in these sections, or may mention only some of them. We explored using backward citations to introductory papers, but this method proved less precise and biased.

We identified 31,170 patents families citing 14,435 papers from our sample of journal articles and conference proceedings, either on the front-page, in-text, or both888We have decided to include in-text citations as well, because we believe that non-patent literature cited only on the front page would not adequately cover less conventional scientific publications, such as conference proceedings, data introductory papers, and other sources likely to be found throughout the full patent text..\nConsidering the relative distribution of the datasets used by publications in our sample, Figure 2  ###reference_### illustrates the number of yearly publications citing the fifteen most common datasets in computer vision and image recognition literature using ML, accounting for 81.67% of papers. The significant increase, particularly after 2012 \u2014 the year of the DL revolution \u2014 was primarily driven by papers citing ImageNet, MNIST, COCO, and CIFAR-10999For more information on these datasets, visit their official sites: ImageNet  ###reference_image-net.org/###, MNIST  ###reference_###, COCO  ###reference_cocodataset.org/###, and CIFAR-10  ###reference_r.html###., which account for 62.71% of the total sample. CIFAR-10 and ImageNet represent 33.23% of the publications in our sample and show similar trends: both were introduced in 2009 by young scholars who believed in the potential of labeled datasets to advance DL. These datasets consist of natural images and have been used for various tasks such as image classification, object recognition, and image generation101010According to our analysis using the Papers with Code platform, CIFAR-10 has been utilized in 46 unique tasks and ImageNet in 64 tasks, with 24 tasks overlapping between the two (52.17% of CIFAR-10 tasks). See Table B1  ###reference_### for details.. They are the first two most used databases in Papers with Code. The main difference between them is that CIFAR-10 is much smaller, with 60,000 images and 10 categories, compared to ImageNet\u2019s 14,197,122 images and over 20,000 categories. Additionally, ImageNet was central to the ImageNet Large Scale Visual Recognition Challenge (ILSVRC) from 2010 to 2017, which incentivized the development of ML models using this dataset.\nRegarding the other two datasets, MNIST is a dataset of handwritten digits introduced in 1998. It comprises 60,000 training examples and 10,000 test examples, with digits that have been size-normalized and centered in fixed-size images. COCO, introduced in 2014 by a Microsoft group, contains images of complex everyday scenes with common objects in their natural context. It includes 91 object categories, 82 of which have more than 5,000 labeled instances, totaling 2,500,000 labeled instances in 328,000 images. Unlike ImageNet, COCO has fewer categories but more instances per category, and it is used for tasks such as detection, segmentation, and captioning.\nDataset\n\n      \n\nDescription\n\n      \n\nInstances\n\n      \n\nPrimary Task\n\n      \n\nYear Introduced\n\n      \n\nCreator Affiliation\n\n      \n\nCurrent Best Model Performance\n\n      \n\nHardware Burden\n\n      \n\nEstimated Time on Super- computer\n\n      \n\nEstimated Time on Laptop\n\n\n      \n\nCOCO\n\n      \n\nComplex everyday scenes of common objects in their natural context\n\n      \n\n2,500,000\n\n      \n\nObject recognition\n\n      \n\n2015\n\n      \n\nMicrosoft\n\n      \n\nModels today only reach error rates up to 38.7%\n\n      \n\nTarget error rate of 10% requires estimated  flops\n\n      \n\n years\n\n      \n\n years\n\n\n      \n\nImageNet\n\n      \n\nLabeled object image database\n\n      \n\n14,197,122\n\n      \n\nObject recognition, classification\n\n      \n\n2009\n\n      \n\nPrinceton University\n\n      \n\nBest model OmniVec reached error rate of 8%\n\n      \n\nReaching human-level error rate of 5% requires  flops\n\n      \n\n years\n\n      \n\n years\n\n\n      \n\nCIFAR-10 Dataset\n\n      \n\nMany small, low-resolution, images of 10 classes of objects\n\n      \n\n60,000\n\n      \n\nClassification\n\n      \n\n2009\n\n      \n\nUniversity of Toronto\n\n      \n\nMost models can reach 99%+ accuracy\n\n      \n\nReaching human-level error rate of 6% requires  flops\n\n      \n\n minutes\n\n      \n\n230 days\n\n\n      \n\nMNIST database\n\n      \n\nDatabase of handwritten digits\n\n      \n\n70,000\n\n      \n\nClassification\n\n      \n\n1994\n\n      \n\nAT&T Bell Labs\n\n      \n\nMost models can reach 99%+ accuracy\n\n      \n\nTo train a similar model  flops\n\n      \n\n seconds\n\n      \n\n seconds\n\n\n\n\u2022\n\nNotes: This table shows the computational requirements to train State-Of-The-Art (SOTA) ML models using the 4 most common dataset in our sample. See methodological appendix for the construction of the table. Source: \\textciteshermatov_national_2024.\nTable 1  ###reference_### provides an overview of the computing capacity required for the four most commonly used datasets. Using the best supercomputer in 2024 and a typical research laptop as benchmarks, and referencing state-of-the-art algorithms that outperform humans on CIFAR-10 and MNIST, it is clear that MNIST is now too simple for complex tasks, while COCO remains too challenging to solve fully. Therefore, we believe ImageNet is the best candidate for comparison with CIFAR-10. It is important to note that CIFAR-10 is both sufficiently complex and manageable in size. For instance, training a model to achieve human-level accuracy of 94% on CIFAR-10 would take an average research laptop about 10 seconds \\parencitejordan_94_2024.\nTo analyze the citation patterns described in Section 4.1  ###reference_###, we consider only publications between 2010 and 2022, reducing our sample to 36,859 publications111111Few papers used large labeled datasets before the DL revolution in 2012, thus we lose very few papers in this step. We chose 2010 as the starting year because it marks the introduction of the two most popular OLDs to the ML community: CIFAR-10 and ImageNet. We further restrict our sample to conference proceedings and journal articles, as these are the types of publications where we expect to see ML models trained using OLDs, excluding review papers and data introduction papers. This restriction leaves us with a sample of 35,705.\nSince we want to compare similar articles, we removed those lacking fundamental bibliometric information used as control variables121212We have 28 publications missing author information, 1,761 missing references, 1,074 missing affiliation information, and 4 missing subject area information. We also exclude 2 papers that came from dataset that are described in Papers With Code, but do not have any paper indexed to it in the platform.. Additionally, not all publications indexed by Scopus can be found in Reliance on Science and vice versa, due to duplicated IDs and other issues. Thus, to ensure reliable information about patent citations, we drop from our sample 4,944 conference proceedings and journal articles for which we cannot confirm the number of patent citations received. This leaves us with 28,416 papers and proceedings131313We perform robustness checks using the sample without excluding those publications in Appendix D  ###reference_###..\nAmong these, we identified 23 papers (top 0.1% in the citation distribution of the full sample and 0.08% in the restricted sample) as outliers, which received citations orders of magnitude higher than the others141414The most cited paper in our sample is \u201dDeep Residual Learning for Image Recognition,\u201d published in the Proceedings of the IEEE/CVF Conference on Computer Vision and Pattern Recognition by a Microsoft group. This paper introduced the Residual Networks (ResNet) architecture, a key component in modern DL models (e.g., Transformers, AlphaGo Zero), and has received 95,139 citations. It was the most cited paper globally for five consecutive years, according to Google Scholar (source: Nature Index  ###reference_oogle-scholar-reveals-most-influential-papers-research-citations-twenty-twenty-one###).. These publications represent breakthroughs so significant that they are not comparable with the average paper in the field. To ensure the comparability, robustness, and stability of our estimations, we excluded these outliers from our sample.\nStatistic\nN\nMean\nSt. Dev.\nMin\nPctl(25)\nMedian\nPctl(75)\nMax\n\nCIFAR-10\n28,393\n0.154\n0.361\n0\n0\n0\n0\n1\n\nCIFAR-10 (only)\n28,393\n0.041\n0.198\n0\n0\n0\n0\n1\n\nImageNet\n28,393\n0.199\n0.399\n0\n0\n0\n0\n1\n\nNb.

Table 2  ###reference_### provides descriptive statistics for our regression sample. Approximately 15.4% of the sample cited the CIFAR-10 dataset in the ten years following its release, while 19.9% cited the ImageNet dataset. However, only 4.1% cited CIFAR-10 exclusively, indicating that CIFAR-10 is often used alongside other datasets. On average, each paper cites only 1.3 datasets, with the third quartile being 1 dataset. The average number of authors per paper is 4.32, and 24.5% of the papers include at least one international collaboration (i.e., authors from multiple countries). Private companies are represented as well, with 4% of authors affiliated with companies (9.4% of the papers have one company affiliated author). Focal papers have an average of 36 backward citations and 16 forward citations, with considerable variation. The average number of different modalities used is 1.25, indicating that most papers focus solely on images. Finally, the number of unique tasks overlapping with CIFAR-10 tasks across all datasets used in the focal papers is approximately 16, representing 34.5% of similar tasks. In summary, this sample consists of papers using the most common labeled datasets in computer vision, with tasks closely related to those central to the DL revolution."

+            "text": "Bridging the gap - Dataset characteristics. From the interviews that we conducted, the first element that prominent practitioners mentioned, was how CIFAR-10 went a step ahead of the MNIST but was more manageable than ImageNet, creating a sort of bridge between those two moments of the development of DL.\nYoshua Bengio (2022, Interview No. 05) mentions how the team at CIFAR had achieved some success with MNIST but \"we didn\u2019t have datasets of comparable size for natural images\". This was confirmed by Rob Fergus (2022, Interview 02), and Yan LeCun (2022, Interview No. 4) both of whom mentioned that there was a \"gap\" that CIFAR-10 helped to fill.\nAn important element that made CIFAR-10 a bridge is that it used a small number of categories, like MNIST, but also natural images, like ImageNet.\nIt was much harder than the 10 digits [of MNIST], it was much, much harder. So it was useful, but the size was the same 60,000 training examples. So that mean, we could use the same kind of architectures. (Bengio, 2022, interview No. 05).\nThat also helps explain why it was CIFAR-10 (and not CIFAR-100) the one that had the most impact:\nYes, CIFAR 10 was the one that really had a big impact. For one it was exactly the same format that MNST, 10 categories. When people started working with CIFAR 100, it was much harder. So there are 100 categories, yeah, but you have the same amount of data so that the accuracy is much worse. So CIFAR 100 has been used, but as far as I know, not nearly as much as CIFAR 10. (Bengio, 2022, Interview No. 05).\nTesting architectures and scaling up. The second element that emerges from the interviews it that CIFAR-10 was simple enough to test and iterate different algorithms and architectures, without requiring prohibitive amounts of computer power. Those architectures could then be used in more challenging datasets. Yoshua Bengio, Yan LeCun and Rob Fergus insisted, in very similar terms, on the potential of CIFAR-10 for trying different architectures and iterate experiments:\nSo in a way, what I\u2019m trying to say is working with CIFAR-10 we discovered architecture tricks, if you want a methodology, for training deeper networks that Alex was then able to apply to ImageNet. So, yeah, CIFAR-10 was kind of instrumental on the path to the modern revolution of computer vision with DL. (Bengio, 2022, Interview No. 05).\nSo I think, when you\u2019re trying to develop a new method, you\u2019ve got to be able to iterate experiments quickly. And ImageNet is still, [\u2026] a bit too big to do that with. And it turns out that the performance on CIFAR-10 generalizes quite well to other data sets like ImageNet. So, you can prototype on CIFAR-10. And then, you know, get some promising stuff, and then move over to something a bit bigger and harder. (Fergus, 2022, Interview No. 02).\nThis characteristic became instrumental in the development of AlexNet, which marked the turning point in the DL revolution:\nThe AlexNet paper, I\u2019m not sure would have happened, had it not been for CIFAR-10. Because otherwise, it would have been very difficult for them [Alex and Ilya] to go directly to the ImageNet dataset, which was quite new at the time, and definitely quite big at the time, too, and challenging to use. (Fergus, 2022, Interview No. 02)\nPedagogical potential. The third element that according to the interviewees help explain the success and persistence of CIFAR-10 as relevant tool for DL, is its pedagogic value. Since working on it does not require onerous computational capabilities, it can be easily used for teaching purposes.\nBengio notes that:\nMy students started to use it pretty soon, like, we were hungry for that. And we were aware of it even before it was released, because Geoff [Hinton] was talking about it. And you know, we were in close communication with Geoff [Hinton]. Bengio (2022, Interview No. 05)\nIn the same line of reasoning, Fergus stated:\nOnce you\u2019ve got a lot more people interested in DL, it was a great sort of introductory data set. I mean, small enough, you can do it in, you know, if you\u2019re teaching a class, you can use it, because every student can run CIFAR-10 on their laptop, more or less.

The vast majority of respondents (228) hold a Doctorate degree (PhD), and most of the respondents are employed in academia. 20% of respondents work in industry or in a combination of industry and academia, when we look at the article affiliation we find a much lower share, about 11%, confirming the importance of mobility of researchers from academia to industry.\nThe Importance of the Datasets. Figure 3  ###reference_### reports responses on the importance of CIFAR-10 for the development of DL and Computer Vision were overwhelmingly positive. 76% believe CIFAR-10 was very or extremely important for the development of DL and 73% for the development of Computer Vision. 44% considered CIFAR-10 as extremely important for the development of DL in general, not only for Computer Vision. Though CIFAR-10 included labeled images, it is considered important for the development of the general field of DL.\n###figure_3### Notes: This figure shows the distribution of answers for the Impact question.\nUse compare to other OLDs. We asked the respondents to rate the reasons why they choose CIFAR-10 compared to similar datasets in the public domain. Based on our interviews we included the quality of labelling, comparability as a benchmark, number of categories and images, image size, and data availability. Respondents rated each section on a Likert scale ranging from 1 (not important) to 5 (extremely important). Figure 4  ###reference_### present the results of this questions. Around 90% of respondents rated availability and comparability as very or extremely important. Quality of labelling and number of images were also considered important in explaining the choice of CIFAR-10 by 72% and 66% of the respondents.\n###figure_4### Notes: This figure shows the overall distribution of response for the question comparing CIFAR-10 to other datasets.\nPedagogical use of the datasets. Figure 5  ###reference_### reports an interesting dimension of the survey: the pedagogical use of CIFAR-10. A significant number of respondents - 193 (65%) - reported that they were introduced to the dataset during their studies (at the Bachelor, Master, or PhD level), and most respondents in academia routinely use it in their teaching programs. Furthermore, the responses to the open-ended question highlight the importance of CIFAR-10 as a pedagogical tool.\n###figure_5### Notes: The graphs illustrate the responses of participants regarding their usage of CIFAR-10 in teaching, as well as their introduction to CIFAR-10 based on their academic background.\nThe last question of the questionnaire was open, we asked to describe why they thought that CIFAR-10 was important for the development of DL or CV. Out of the 295 complete questionnaires analysed, we have got 182 quite detailed answers with a lot of interesting insights. To analyse them we have used the premium version of ChatGPT asking the algorithm to \"identify the 5 main themes in the list of answers\".\n1. Benchmarking and Comparison: CIFAR-10 is frequently cited as a standard benchmark for evaluating and comparing the performance of various algorithms and models. It provides a common platform for fair comparisons and validation, which is essential for developing and testing new methods in DL and computer vision.\n2. Accessibility and Ease of Use: The dataset is noted for its accessibility and ease of use. It is readily available, simple to download, and manageable in terms of size and computational requirements. This makes it an ideal choice for both beginners and researchers without access to extensive computational resources.\n3. Educational Value and Prototyping: CIFAR-10 serves as an excellent educational tool for new learners and students. Its simplicity and comprehensibility makes it a good starting point for understanding and experimenting with DL concepts. Additionally, it is suitable for rapid prototyping and initial testing of new ideas before scaling up to more complex datasets.\n4. Quality and Characteristics of the Dataset: The dataset is appreciated for its well-labeled, high-quality images. It offers a balanced number of categories and samples, which are sufficiently challenging for various image classification tasks. Its small image size and the diversity of the data allow for efficient experimentation and training..\n5. Historical and Continued Relevance: CIFAR-10 has historical significance in the field of computer vision and DL, having been used in many foundational studies and developments. Despite advancements in technology and the availability of larger datasets, it remains relevant due to its widespread use and the wealth of existing research that has utilized it as a benchmark.\nWe also created a word cloud of the most common terms used in the answers to the open question151515The word cloud was generated using Voyant Tools, an online open-source text analysis software available at https://voyant-tools.org/.. We excluded some frequently used terms like \"CIFAR\" and \"database\", to get a more accurate idea of the reasons respondents assign importance to CIFAR-10. Figure 6  ###reference_### shows that \"benchmarking\" and \"learning\" are the most used terms, with 49 and 41 times respectively. These results are consistent with the analysis made through ChatGPT.\n###figure_6### Notes: This figure shows the most common terms used by respondents in the open-ended question on why CIFAR-10 was important for the development of DL or CV.\nThe evidence from both interviews and survey is consistent in highlighting that the specific characteristics (size, complexity, generalization) of CIFAR-10 made it the technological tool needed to develop and test convolutional neural network algorithms that gave rise to DL revolution. We also find consistent evidence that the accessibility, versatility, use as benchmark and pedagogical use of CIFAR-10 supported its continuous use and relevance even if much more complex and targeted OLDs became available in the ten years after its release."

Columns 1-3 presents results for specification 1  ###reference_###. As we can observe in column 1, on average papers that mention only CIFAR-10 or CIFAR-10 and other datasets between 2010 and 2022 receive less citations than paper that do not cite it, but this difference is not statistically significant at conventional confidence levels. However, if we taken into consideration only the first half of the 2010 decade (2010 to 2014) as in column 2, we find that papers using only CIFAR-10 or CIFAR-10 and others accrued on average 64.38% and 181.51% more citations than articles using other datasets. When considering the period post-2014 (2015 to 2022) in column 3, we see that papers using CIFAR-10, both alone and in combination with other datasets, received fewer citations compared to the average citations received by other papers. The results in column 3 are significant in both magnitude () and statistical terms for papers using CIFAR-10 along with other datasets, suggesting that the scientific citation impact of CIFAR-10 was primarily concentrated in its early years.\nScientific Citations\n\n\nFull\n2010-2014\n2015-2022\nFull\n2010-2014\n2015-2022\n\nModel:\n(1)\n(2)\n(3)\n(4)\n(5)\n(6)\n\nCIFAR-10 (only)\n-0.026\n0.497\u2217\u2217\n-0.051\n0.108\n0.701\u2217\u2217\u2217\n0.082\n\n\n(0.090)\n(0.172)\n(0.101)\n(0.095)\n(0.186)\n(0.108)\n\nCIFAR-10 (others)\n-0.294\n1.035\u2217\n-0.346\u2217\n-0.155\n1.374\u2217\n-0.207\n\n\n(0.191)\n(0.489)\n(0.156)\n(0.216)\n(0.584)\n(0.179)\n\nImageNet\n\n\n\n0.386\u2217\u2217\u2217\n0.594\u2217\n0.384\u2217\u2217\u2217\n\n\n\n\n\n(0.092)\n(0.284)\n(0.092)\n\nlog(Nb.

The results in column 4 indicate that, overall, papers mentioning CIFAR-10 do not differ significantly in terms of scientific citations compared to those mentioning other datasets. In contrast, papers mentioning ImageNet receive significantly more citations on average (). However, the difference in citations between papers mentioning CIFAR-10 and those not mentioning it is positive and significant in the first period (column 5) but becomes statistically insignificant in the last period (column 6). Meanwhile, papers using ImageNet consistently receive more citations on average in every period, though they received fewer citations than papers using CIFAR-10 in the first period. Specifically, during 2010-2014, papers mentioning CIFAR-10, either alone or with other datasets, received 101.58% and 295.11% more citations, respectively, compared to those using other datasets but not ImageNet. In comparison, papers using ImageNet received 81.14% more citations than those not using CIFAR-10.\nRobustness Checks.\nIn Appendix D  ###reference_###, we perform a series of robustness checks and sensitivity analysis using various estimation methods, different sample definitions, and alternative model specifications.\nAlternative Statistical Models. The Poisson model is not the only method for handling highly skewed count data161616Another approach involves using OLS to estimate models with log-transformed dependent variables or employing the inverse hyperbolic sine transformation. We chose not to use these estimation methods because our dependent variables include many zeros, and results can be sensitive to the arbitrary addition of a constant to handle these zero observations.. Table D1  ###reference_### presents estimates from a negative binomial regression171717Negative binomial regressions lack a fixed-effects estimator that is as consistent as the one in the Poisson fixed-effects model. To address this, we substitute fixed effects with categorical variables that control for the same factors as the fixed effects in the Poisson model. based on specification 1  ###reference_###. When scientific citation count is used as the dependent variable, the direction of the CIFAR-10 indicator variable coefficients remains consistent, although the significance levels differ. This alternative model does not alter our main finding: the influence of CIFAR-10 in scientific literature is predominantly concentrated in the earlier period. Results for patent citations are qualitatively similar.\nFurther Restricted Sample. The publications in our initial sample are quite diverse, including both journal articles and conference proceedings. To improve comparability, we further refine our sample to include only conference proceedings. These proceedings are more likely to represent recent advancements in ML models using labeled datasets. We restrict this further to papers that utilize datasets covering at least 10% of the tasks addressed by CIFAR-10 and are indexed in Papers With Code, aiming to minimize noise. Table D2  ###reference_### presents results for patent citations, while Table D3  ###reference_### shows results for scientific citations. The findings are qualitatively similar to our main results and exhibit greater significance and magnitude, providing additional evidence of the influence of CIFAR-10 and ImageNet on technological and scientific advancements in DL. In patents citations is confirmed the stronger and continuous use of CIFAR-10 compared to ImageNet.\nEnlarged Sample. To ensure consistency in comparing patent and scientific citations, we initially removed a substantial number of observations where patent citations could not be accurately measured (13.86% of papers with missing patent citation values), as well as various publication types such as reviews, book chapters, and data papers. We then re-estimated our main specifications using an enlarged sample that includes papers with missing patent citation counts and all publication types for both patent citations (Table D4  ###reference_### and scientific citations (Table D5  ###reference_###. The results are qualitatively consistent with our original findings.\nAlternative Dataset Indicator Variable. Since papers often benchmark new ML models against multiple datasets, isolating the citation impact of dataset size and complexity is challenging. To address this issue, we refined our indicator variable to distinguish between papers using only CIFAR-10 and those using CIFAR-10 in combination with other datasets. The variable for papers using only CIFAR-10 is more likely to reflect the effect of a small, yet sufficiently large, dataset, while the variable for papers using CIFAR-10 alongside other datasets also captures the influence of combining multiple datasets. To test the sensitivity of our analysis to this variable definition, we estimated models with an alternative specification where the independent variable is set to 1 for any publication mentioning CIFAR-10, regardless of whether it is used alone or with other datasets, and 0 otherwise. Table D6  ###reference_### shows that while the results for patent citations are consistent in sign with the full sample and the 2015-2022 period, they are no longer statistically significant. This suggests that papers more significant in technological development predominantly use CIFAR-10 alone, supporting the idea that small-but-large-enough datasets play a unique role in advancing DL models in computer vision. Results in Table D7  ###reference_### are qualitatively similar and confirm our main findings.\nCitation Lags. DL has experienced rapid growth in recent years, especially following the 2012 revolution and the release of the ChatGPT chatbot at the end of 2022. This surge has arguably heightened interest in older publications in the field and altered citation patterns in ways that publication year fixed effects may not fully capture. To assess the sensitivity of our results to different citation specifications, we compare citation counts within a fixed number of years after publication. This approach helps account for the dynamic nature of citation trends. Given the recent nature of our sample, we focus on a 3-year citation window to avoid losing too many observations from more recent years. Tables D8  ###reference_### and D9  ###reference_### present the results for patent and scientific citations within this 3-year window, respectively, demonstrating that the findings remain qualitatively consistent.181818We also conducted the analysis using the citation count of patent families sourced from Elsevier\u2019s PlumX Analytics. This metric includes only front-page citations from the European Patent Office (EPO), World Intellectual Property Organization (WIPO), Intellectual Property Office of the United Kingdom (IPO), United States Patent and Trademark Office (USPTO), and Japan Patent Office (JPO). The results were qualitatively similar.\nOverall, our main results remain consistent, confirming the robustness of our findings across various control variables, fixed effects, sample definitions, and model specifications."

The timing of its release was also crucial to its popularity, as no other similar OLD was available at the time. ImageNet, released in 2009 by a team of university researchers and associated with the ImageNet Large Scale Visual Recognition Challenge, was also significant but proved too large and complex. Even today, in 2024, solving ImageNet with the best model and the largest supercomputer would take more than three years.\nThe survey confirms the insights from the interviews and reveals an additional role that CIFAR-10 played in the diffusion of DL methods. We present evidence that CIFAR-10 is extensively used in training computer scientists working with ML. Many researchers not only teach courses using CIFAR-10 but were also exposed to the datasets during their own graduate programs. This finding highlights teaching as a significant channel through which CIFAR-10 influences the field of DL.\nThe econometric analysis of the technological and scientific roles played by OLDs confirms that CIFAR-10 has had a significant influence on the development of DL compared to other OLDs, including its closest competitor, ImageNet. For science, we find that CIFAR-10\u2019s contribution was particularly important in the early years of DL development, with patent citations to CIFAR-10 remaining frequent in recent years. The role of ImageNet for the development of DL has been more prominent and continuous, likely due to its complexity, which allows for the testing and development of more advanced models. However, CIFAR-10 continued to outperform ImageNet (and all other OLDs) in technological citations even in recent years.\nIn terms of scientific complexity, CIFAR-10 was effectively \"solved\" by 2014, when state-of-the-art DL models achieved an error rate of around 3-4%, surpassing human-level accuracy in image classification tasks. Its sufficient complexity and status as a benchmark make it particularly useful in applied industrial research, where the speed of research and cost controls are more important than new scientific achievements. This continued use and technological relevance can explain the frequency of patent citations in recent years.\nBased on the qualitative and quantitative evidence collected, it can be argued that CIFAR-10\u2019s lower computational requirements, ease of use, and the availability of a trained workforce make it more suitable for technology-oriented developments, as reflected in patent activity. These developments, which focus less on pushing the scientific frontier, are likely to rely more on CIFAR-10 compared to ImageNet and other more recent, complex datasets. The latter\u2019s increased complexity and higher computational demands make it less accessible for such practical applications.\nThis study has some limitations. First, while we have tried to interview active researchers in computer vision during the DL revolution, we were unable to interview the creators of CIFAR-10, Geoffrey Hinton, Vinod Nair, and Alex Krizhevsky. Gaining further insight into their motivations could illuminate the choice of dataset characteristics and how these are related to the development of DL models they were working on. Another limitation is the difficulty in identifying the specific OLDs used in each paper. Despite experimenting with different approaches, pinpointing the datasets in ML papers remains challenging. Future studies could employ more precise extraction algorithms to identify the datasets used, leveraging the full text of papers. Additionally, this study is primarily descriptive, making it challenging to establish causal effects of dataset usage. We do not observe the full process of building and refining ML model architectures or which datasets were effectively used prior to publication. Forthcoming investigations could exploit exogenous shocks in the availability of OLDs to understand their impact on the development of the field."

Understanding the fundamental building blocks of this emerging technoscience is crucial, as these foundational elements will likely impact socioeconomic development in the coming years. Current advancements continue to be influenced by early events.\nWe find that CIFAR-10, a small yet sufficiently complex, well-labeled, and easily accessible database, was fundamental for the developments leading to the DL revolution and continues to shape the field\u2019s trajectory. We identify CIFAR-10 as one of the most important technological artifact used to develop DL algorithms and architectures. We trace the creation of this dataset to the CIFAR NCAP Summer School in 2008, where graduate students, supervised by Geoffrey Hinton, a prominent scholar in the field, carried out the labeling of the datasets.\nThe evolution of AI in the early 2020s has been marked by significant investments by private companies in data collection and computing capacity to develop advanced large language models (LLMs) expected to profoundly impact society. A few large companies, which have been recruiting top DL scientists (similar to the career trajectory of the lead scientists behind CIFAR-10) and attracted a substantial share of new graduate and postgraduate DL researchers (as evidenced by the current debate on universities\u2019 challenges in retaining DL scientists and our own data on the share of researchers working for companies), have the capacity to shape both the scientific and technological trajectory of DL.\nPreviously, the field developed with an open science approach, where public and private actors adhered to the ethos of open science by sharing data and methods. However, this approach has changed significantly. We may be entering a new phase in DL development characterized by a more traditional separation between science and technology, consistent with \\textciteparthaNewEconomicsScience1994 characterization of traditional science. If this is the case, there is an urgent need for substantial investment in public science conducted at universities. The \"small is beautiful\" model exemplified by the CIFAR-10 database may no longer be viable. Nonetheless, the widespread diffusion of CIFAR-10 and its origins reflect a human capital imprint of \"open science\" ethics that could be leveraged to maintain competitive dynamics in the DL field."

Some of these interviews contributed to refining the research question, others provided empirical material for our conclusions, and some served both purposes.\nInterview number\n\n\n\nInterviewee\n\n\n\nAffiliation\n\n\n\nPosition\n\n\n\nInterviewer\n\n\n\nDate\n\n\n\n\n1\n\n\n\nBruno Casella\n\n\n\nUniversity of Turin\n\n\n\nPhD student\n\n\n\nDaniel Souza\n\n\n\n12/07/2022\n\n\n\n\n2\n\n\n\nRob Fergus\n\n\n\nNYU/ DeepMind\n\n\n\nProfessor/ Researcher Scientist\n\n\n\nDaniel Souza/ Aldo Geuna/ Jeff Rodriguez\n\n\n\n21/07/2022\n\n\n\n\n3\n\n\n\nGianluca Mittone\n\n\n\nUniversity of Turin\n\n\n\nPhD student\n\n\n\nDaniel Souza\n\n\n\n26/07/2022\n\n\n\n\n4\n\n\n\nYann LeCun\n\n\n\nNYU/Meta AI\n\n\n\nProfessor/VP & Chief AI Scientist\n\n\n\nDaniel Souza/ Aldo Geuna\n\n\n\n28/07/2022\n\n\n\n\n5\n\n\n\nYoshua Bengio\n\n\n\nUniversit\u00e9 de Montr\u00e9al\n\n\n\nFull Professor\n\n\n\nDaniel Souza/ Aldo Geuna/ Jeff Rodriguez\n\n\n\n17/10/2022\n\n\n\n\n6\n\n\n\nRachel Parker\n\n\n\nCIFAR\n\n\n\nSr Director, Research\n\n\n\nDaniel Souza/ Aldo Geuna/ Jeff Rodriguez\n\n\n\n18/11/2022\n\n\n\n\n7\n\n\n\nMelvin Silverman\n\n\n\nCIFAR\n\n\n\nFormer VP of Research\n\n\n\nDaniel Souza/ Aldo Geuna/ Jeff Rodriguez\n\n\n\n08/12/2022\nThe selection of interviewees was opportunistic, leveraging existing contacts. From these initial contacts, we employed a snowball sampling method to reach individuals outside our direct network, focusing on those recommended by interviewees and those with experience directly related to the creation of CIFAR-10 and CIFAR-100. Additionally, we conducted shorter interviews with individuals peripherally related to the topic, selected for their direct, personal knowledge of specific facts. This approach resulted in seven in-depth interviews that were transcribed, along with many off-the-record conversations.\nWe framed the interviews as conversations, with most conducted online and a few by phone, typically lasting between 15 minutes to an hour. Whenever permission was granted, we recorded the conversations, though participants could designate specific comments as off the record at any time. They were also given the option to review sections of the article in which they were mentioned before publication to ensure accuracy and agreement with how their comments were used. Interviewees had the choice to determine whether they wished to be identified by name or remain anonymous.\nInterview Guide. In-depth interviews were based on a guide reproduced below, which aws adapted in minor ways for each interview to reflect the fact that not all interviewees would have the same information to impart.\nFinal Interview Guide for In-Depth Interviews\nResearch Question:\nWhat is the impact of CIFAR-10/CIFAR-100 on the development of Deep Learning?\nInterview goal: Understand the role of CIFAR-10 and CIFAR-100 in the Deep Learning Revolution. We are also trying to better understand the chain of events that led to the development of these two datasets around 2008/2009, particularly the Summer School of August 2008.\nQuestions:\nWhat was the impact of CIFAR-10/CIFAR-100 databases and how would you measure it?\nDid it help the development of neural network algorithms?\nDid it help the development of computer vision?\nDid it help the development of other research topics in artificial intelligence?\nShould we measure the impact on publications?\nShould we measure the impact on patents?\nShould we measure the impact on working papers?\nShould we measure the impact on conference proceedings papers?\nShould we measure the impact on media?\nCan you tell us about the history of the AI projects at CIFAR?\nHow was the process of creating CIFAR-10/CIFAR-100?\nDo you remember the NCAP summer school of 2008? Was that the moment in which CIFAR-10/100 were born? Was the whole process of labelling finished during the summer school or did it require additional work?\nWho decided to give the name of CIFAR in CIFAR-10/100? Was it related to the funding of the project?\nWrap-up\nWho else do you think I should engage on this in relation to their work with CIFAR-10/CIFAR-100?\nAre you interested in seeing the results of this research?\nThank you, very grateful for your time and thoughts.\nTranscription. Most interviews were recorded and transcribed by the authors. When interviewees declined to be recorded, or when recording was impractical, shorthand notes were taken during the interview and subsequently expanded into detailed notes as soon as possible afterward.\nSurvey. The inputs from the interviews were used to produce a survey that was distributed to ML practitioners and academics.\nThe questionnaire consisted of 9 questions; 3 of the questions were related to the informant (education, place of work), and 4 directly to the evaluation of the CIFAR datasets. Figure A1  ###reference_### shows the full battery of questions.\n###figure_7### ###figure_8### To select the universe of possible respondents, we used the contact details of authors of papers extracted from Scopus that had used CIFAR-10 in their research. Out of the total of 6060 papers extracted, we were able to recover a valid email address of a corresponding author for 3033 papers. We sent a total of 4 requests to answer to the questionnaire to those authors in the period September 2022 to February 2023.\nThe survey had a response rate of 9.7%, with 392 authors starting the survey (13%) and 295 completing it. The authors were from different geographical locations, with most affiliations in China and the US.\n###figure_9### Source: done by the authors\n\\floatfootNotes: The graph illustrates the fractional count of papers based on affiliations. The top 20 affiliations listed in the graph collectively account for 90% of the the CIFAR papers.\nDescriptive Statistics for Total Population of Papers\n\nStatistic\nYear\nNumber of Authors\nCitation Count\nType Publications\nInt.

These variables include publication year, number of authors, citation count, journal publications (using journal publications from aggregation type as a benchmark of comparison), international collaboration, number of datasets used, use of the Imagenet dataset and affiliation of authors. The table shows the number of observations (N), the number of unique values (Ndist), the mean, standard deviation, minimum, maximum, and 25th and 75th percentiles for each variable. Table 1 provides statistics for the entire population, while Tables 2 and 3 present statistics for subsets of papers based on whether they had corresponding email addresses and whether their authors responded to our survey. At the bottom of each table, we report the results of the Kolmogorov-Smirnov test, which assesses the distributional differences between the variables in different tables. Specifically, we report the results of the KS test between Table 1 and Table 3, Table 1 and Table 2, and Table 2 and Table 3, to identify any significant differences in the distribution of variables between the tables. These tables offer valuable insights into the characteristics of the papers in our sample and provide a foundation for further analysis.\nTable A2  ###reference_### presents the summary statistics of our response analysis. The table includes the Kolmogorov\u2013Smirnov test (addressing the variance in the distribution) to compare the three sample considered: Total population, Population Survey Sent and Population Survey Answered. We included in our response analysis the following variables: Year of publication, Number of authors, Citations count, Type publication (Journal versus others), International collaborations, Number of OLDs used, Use of ImageNet and Authors affiliated to a company.\nThe year of publication was the only factor hypothesis rejected by all of the three tests. Respondents are associated to papers published more recently, however the difference is only in term of months, and is mainly due to no response from a few old papers. There are no significant differences between respondents and the population for which we had the email for the other seven variables we have considered.\nWhen we compare respondents to the total population we see that journal articles are more frequent compare to other outlets, this is due to the fact that email addresses are difficult to be found in proceedings thus the email population was already biased in favour of journals. The respondent sample includes also papers with fewer citations compared to the total population; the bias was already present in the email population as the most highly cited articles are in category of proceedings."

A list of CIFAR-10 and ImageNet tasks can be found in table B1  ###reference_###. Missing introduction dates were filled automatically by querying for the name of the introductory paper on Scopus or manually when the introductory paper was unavailable. Additionally, we collected data on the number of papers indexed in Papers With Code connected to each dataset.\nWe then queried the Scopus API using Pybliometrics with the following query structure for each dataset name:\nTITLE-ABS-KEY(\"dataset\") AND PUBYEAR AFT intro-year.\nThis query identified papers published after the year of introduction, allowing for a two-year margin to account for discrepancies between the first online appearance and official publication dates.

Elaborated by the authors.\nAdditionally, we constructed Table 1  ###reference_### using estimates from \\textciteshermatov_national_2024 to provide computational requirements for running state-of-the-art (SOTA) models on the four most commonly used open labeled datasets (OLDs) in the literature: ImageNet, COCO, MNIST, and CIFAR-10. These estimates were derived from Epoch AI\u2019s methods for assessing the training compute of deep learning systems, including operation counts, GPU time, and performing calculations based on SOTA data compiled by the Papers with Code  ###reference_paperswithcode.com/sota### platform. More details can be found at https://epochai.org/blog/estimating-training-compute  ###reference_ng-compute###.\nThese calculations are intended for illustrative and comparative purposes only. Computing power requirements can differ significantly across datasets and architectures. We provide rough estimates by comparing the compute demands of leading models with the compute capabilities of different hardware. We present estimates for hardwares with two levels of performance: supercomputers and research laptops. For supercomputers, we use the Frontier exascale machine, which delivers 1194 PFlop/s, as a benchmark. For research laptops, we reference average devices with NVIDIA GeForce RTX 4080  ###reference_rce-rtx-4080.c3888### or AMD Radeon RX 7900 XTX GPUs  ###reference_on-rx-7900-xtx.c3941###, which provide roughly 5x less flops/s. Actual flops allocated for deep learning tasks can vary greatly depending on the specific model and its configuration.\nFor example, the top CIFAR-10 model by Google Research Brain Team, ViT-H/14, requires a substantial amount of flops to achieve 99.5% accuracy. A simpler model, \u201cairbench\u201d, requires 3.6 times fewer flops to achieve human-level accuracy of 94% \\parencitejordan_94_2024. On an average researcher laptop, training this model on CIFAR-10 would take approximately 10 seconds to achieve 94% accuracy."

The response variables are indicator variables that are equal to one if a paper mentions only CIFAR-10, CIFAR-10 among other datasets or ImageNet in the title, abstract or keywords. Columns (1) reports our baseline results of the estimates stemming from a Poisson regression. Column (2) and (3) reports estimates of the same equation in a subset of the sample comprised of papers published from 2010 to 2014 and those published from 2015 to 2022, respectively. Columns (4 - 5) report estimates when adding a dataset indicator variable also for papers using ImageNet. Exponentiating the coefficients and differencing from one yields numbers interpretable as elasticities. All the specifications include publication venue type, publication year and scientific field fixed effects. Standard errors are clustered at the journal/conference level.

The response variables are indicator variables that are equal to one if a paper mentions only CIFAR-10, CIFAR-10 among other datasets or ImageNet in the title, abstract or keywords. Columns (1) reports our baseline results of the estimates stemming from a Poisson regression. Column (2) and (3) reports estimates of the same equation in a subset of the sample comprised of papers published from 2010 to 2014 and those published from 2015 to 2022, respectively. Columns (4 - 5) report estimates when adding a dataset indicator variable also for papers using ImageNet. Exponentiating the coefficients and differencing from one yields numbers interpretable as elasticities. All the specifications include publication venue type, publication year and scientific field fixed effects. Standard errors are clustered at the journal/conference level.

The table shows the number of observations (N), the number of unique values (Ndist), the mean, standard deviation, minimum, maximum, and 25th and 75th percentiles for each variable. Table 1 provides statistics for the entire population, while Tables 2 and 3 present statistics for subsets of papers based on whether they had corresponding email addresses and whether their authors responded to our survey. At the bottom of each table, we report the results of the Kolmogorov-Smirnov test, which assesses the distributional differences between the variables in different tables. Specifically, we report the results of the KS test between Table 1 and Table 3, Table 1 and Table 2, and Table 2 and Table 3, to identify any significant differences in the distribution of variables between the tables. These tables offer valuable insights into the characteristics of the papers in our sample and provide a foundation for further analysis.</span>\n</span></span>\n</span></span></span>\n</span></span></span></p>\n</span></div>\n</figure>",

The dependent variable for columns (1)-(3) is the total number of patent families citing the focal papers, while for columns (4)-(6) it is the total number of scientific citations received by the focal papers. The response variables are indicator variables that are equal to one if a paper mentions only CIFAR-10, CIFAR-10 among other datasets or ImageNet in the title, abstract or keywords. Columns (1) and (4) reports our baseline results of the estimates stemming from a Poisson regression. Column (2)-(3) and (5)-(6) reports estimates of the same equation in a subset of the sample comprised of papers published from 2010 to 2014 and those published from 2015 to 2022, respectively. Exponentiating the coefficients and differencing from one yields numbers interpretable as elasticities. All the specifications include publication venue type, publication year and scientific field fixed effects. Standard errors are clustered at the journal/conference level.

The dependent variable is the total number of patent families that cited the focal paper. The response variables are indicator variables that are equal to one if a paper mentions only CIFAR-10, CIFAR-10 among other datasets or ImageNet in the title, abstract or keywords. Columns (1) reports our baseline results of the estimates stemming from a Poisson regression. Column (2) and (3) reports estimates of the same equation in a subset of the sample comprised of papers published from 2010 to 2014 and those published from 2015 to 2022, respectively. Columns (4 - 5) report estimates when adding a dataset indicator variable also for papers using ImageNet. Exponentiating the coefficients and differencing from one yields numbers interpretable as elasticities. All the specifications include publication venue type, publication year and scientific field fixed effects. Standard errors are clustered at the journal/conference level.

The dependent variable is the total number scientific citations received by a paper. The response variables are indicator variables that are equal to one if a paper mentions only CIFAR-10, CIFAR-10 among other datasets or ImageNet in the title, abstract or keywords. Columns (1) reports our baseline results of the estimates stemming from a Poisson regression. Column (2) and (3) reports estimates of the same equation in a subset of the sample comprised of papers published from 2010 to 2014 and those published from 2015 to 2022, respectively. Columns (4 - 5) report estimates when adding a dataset indicator variable also for papers using ImageNet. Exponentiating the coefficients and differencing from one yields numbers interpretable as elasticities.

The dependent variable is the total number of patent families that cited the focal paper. The response variables are indicator variables that are equal to one if a paper mentions only CIFAR-10, CIFAR-10 among other datasets or ImageNet in the title, abstract or keywords. Columns (1) reports our baseline results of the estimates stemming from a Poisson regression. Column (2) and (3) reports estimates of the same equation in a subset of the sample comprised of papers published from 2010 to 2014 and those published from 2015 to 2022, respectively. Columns (4 - 5) report estimates when adding a dataset indicator variable also for papers using ImageNet. Exponentiating the coefficients and differencing from one yields numbers interpretable as elasticities. All the specifications include publication venue type, publication year and scientific field fixed effects. Standard errors are clustered at the journal/conference level.

The dependent variable is the total number of scientific publications that cited the focal paper. The response variables are indicator variables that are equal to one if a paper mentions only CIFAR-10, CIFAR-10 among other datasets or ImageNet in the title, abstract or keywords. Columns (1) reports our baseline results of the estimates stemming from a Poisson regression. Column (2) and (3) reports estimates of the same equation in a subset of the sample comprised of papers published from 2010 to 2014 and those published from 2015 to 2022, respectively. Columns (4 - 5) report estimates when adding a dataset indicator variable also for papers using ImageNet. Exponentiating the coefficients and differencing from one yields numbers interpretable as elasticities. All the specifications include publication venue type, publication year and scientific field fixed effects. Standard errors are clustered at the journal/conference level.

The response variables are indicator variables that are equal to one if a paper mentions CIFAR-10 or ImageNet in the title, abstract or keywords. Columns (1) reports our baseline results of the estimates stemming from a Poisson regression. Column (2) and (3) reports estimates of the same equation in a subset of the sample comprised of papers published from 2010 to 2014 and those published from 2015 to 2022, respectively. Columns (4 - 5) report estimates when adding a dataset indicator variable also for papers using ImageNet. Exponentiating the coefficients and differencing from one yields numbers interpretable as elasticities. All the specifications include publication venue type, publication year and scientific field fixed effects. Standard errors are clustered at the journal/conference level.

The response variables are indicator variables that are equal to one if a paper mentions CIFAR-10 or ImageNet in the title, abstract or keywords. Columns (1) reports our baseline results of the estimates stemming from a Poisson regression. Column (2) and (3) reports estimates of the same equation in a subset of the sample comprised of papers published from 2010 to 2014 and those published from 2015 to 2022, respectively. Columns (4 - 5) report estimates when adding a dataset indicator variable also for papers using ImageNet. Exponentiating the coefficients and differencing from one yields numbers interpretable as elasticities. All the specifications include publication venue type, publication year and scientific field fixed effects. Standard errors are clustered at the journal/conference level.

Columns (1) reports our baseline results of the estimates stemming from a Poisson regression. Column (2) and (3) reports estimates of the same equation in a subset of the sample comprised of papers published from 2010 to 2014 and those published from 2015 to 2019, respectively. Columns (4 - 5) report estimates when adding a dataset indicator variable also for papers using ImageNet. Exponentiating the coefficients and differencing from one yields numbers interpretable as elasticities. All the specifications include publication venue type, publication year and scientific field fixed effects. Standard errors are clustered at the journal/conference level. Significance levels: \u2020p&lt;0.1; * p&lt;0.05; ** p&lt;0.01; *** p&lt;0.001.</span>\n</span></span>\n</span></span></span>\n</span></span></span></p>\n</span></div>\n</figure>",

+    "title": "AI-Driven Review Systems: Evaluating LLMs in Scalable and Bias-Aware Academic Reviews",
+    "abstract": "Automatic reviewing helps handle a large volume of papers, provides early feedback and quality control, reduces bias, and allows the analysis of trends. Paper reviews are used by researchers and academics, students, lecturers, innovators and entrepreneurs, policymakers and funding agencies, science journalists, and the general public to navigate research, analyze trends, find educational purposes, and find collaborators. We evaluate the alignment of automatic paper reviews with human reviews using an arena of human preferences by pairwise comparisons. Gathering human preference may be time-consuming; therefore, we also use an LLM to automatically evaluate reviews to increase sample efficiency while reducing bias. In addition to evaluating human and LLM preferences among LLM reviews, we fine-tune an LLM to predict human preferences, predicting which reviews humans will prefer in a head-to-head battle between LLMs. We artificially introduce errors into papers and analyze the LLM\u2019s responses to identify limitations, use adaptive review questions, meta prompting, role-playing, integrate visual and textual analysis, use venue-specific reviewing materials, and predict human preferences, improving upon the limitations of the traditional review processes. We make the reviews of publicly available arXiv and open-access Nature journal papers available online, along with a free service which helps authors review and revise their research papers and improve their quality. This work develops proof-of-concept LLM reviewing systems that quickly deliver consistent, high-quality reviews and evaluate their quality. We mitigate the risks of misuse, inflated review scores, overconfident ratings, and skewed score distributions by augmenting the LLM with multiple documents, including the review form, reviewer guide, code of ethics and conduct, area chair guidelines, and previous year statistics, by finding which errors and shortcomings of the paper may be detected by automated reviews, and evaluating pairwise reviewer preferences. This work identifies and addresses the limitations of using LLMs as reviewers and evaluators and enhances the quality of the reviewing process.",

Previous work addresses the limitations of LLM\u2019s ability to perform reviewing (Liu and Shah 2023  ###reference_b19###) and their capabilities to review academic papers (Liang et al. 2023  ###reference_b17###). Large language models demonstrate surprising creative capabilities in text (Koivisto and Grassini 2023  ###reference_b14###), though they may hallucinate (Zhang et al. 2023  ###reference_b39###), and demonstrate the power to persuade humans even when inaccurate (Spitale, Biller-Andorno, and Germani 2023  ###reference_b33###). This makes controlling the quality and appropriateness of LLM-augmented reviewing highly challenging. At least 15.8% of reviews for ICLR 2024 were written with AI assistance (Latona et al. 2024  ###reference_b16###). Recently, an attempt has been made to automate the entire scientific endeavor including generating research ideas, writing code, running experiments, visualizing results, writing scientific papers, and reviewing (Lu et al. 2024  ###reference_b20###).\nMeta-prompting (Suzgun and Kalai 2024  ###reference_b34###) uses multiple LLM instances for managing and integrating multiple independent LLM queries. Utilizing meta-prompting, the LLM breaks down complex tasks into smaller subtasks handled by expert instances with tailored instructions, significantly enhancing performance across various tasks. This approach outperforms conventional prompting methods across multiple tasks, enhancing LLM functionality without requiring task-specific instructions. Multi-agent review generation for scientific papers (D\u2019Arcy et al. 2024  ###reference_b10###) improves LLM reviewing by using multiple instances of LLMs, providing more specific and helpful feedback by distributing the text across specialized agents that simulate an internal discussion. This reduces generic feedback and increases the generation of good comments. Recent work formulates the peer-review process as a multi-turn dialogue between the different roles of authors, reviewers, and decision-makers (Tan et al. 2024  ###reference_b36###), and finds that both reviews (Latona et al. 2024  ###reference_b16###) and meta-reviews written by LLMs (Santu et al. 2024  ###reference_b30###) are preferred by humans over human reviews and meta-reviews.\nWhy do the Artificial Intelligence, Machine Learning, and Computer Vision communities need AI-based reviews of papers?\n(i) AI-based reviews provide early feedback to authors for their work in progress, allowing authors to learn and improve their work;\n(ii) AI-based reviews would help conferences maintain high-quality and timely reviews for the increasing number of papers in these fields, as shown in Figure 9  ###reference_### in Appendix A  ###reference_###.\n(iii) For quality control of reviews generated while keeping all factors equal;\n(iv) So that the entire community can access thousands of reviews for trend analysis and greater paper contextualization.\n(v) To reduce human biases in the review process; and\n(vi) To direct readership to high-quality papers based on (AI-based) reviewed merit among the hundreds of thousands of papers available online (for example, the number of papers posted on arXiv grew by 12.3% from 185,692 in 2022 to 208,493 in 2023).\nPaper reviews are used for navigating research, analyzing trends, finding collaborators, adequate citation, and educational purposes. We provide the value of reviews made available to a larger audience using OpenReviewer as an AI reviewing tool to power Papers with Reviews. In particular, we envision the following use cases:\nFor authors to improve their papers: adequately citing related work, clarity, soundness etc.\nFor reviewers to help find and refine review points of papers assigned to a reviewer. We note that the recent CVPR 2024 conference banned usage of any LLM for paper reviewing by reviewers, including usage of open-weights LLMs running locally.\nTo assist conference program chairs or journal editors to quickly identify low-quality works for a desk rejection with human oversight.\nFor the academic community, a large-scale corpus of reviews of papers on arXiv, delivering free, high-quality reviews based on merit without direct human biases. Currently, arXiv has a total of over 2.5 million submissions, with over 21 thousand papers and over 60 million downloads a month. The academic community selects papers to read based on factors including their field of interest, community discussion, and popularity on social media. Our AI-generated review scores are a valuable metric for selecting which papers to read based on merit rather than popularity and advertising. We review arXiv papers and make the reviews and scores publicly available online.\nOur key contributions are:\nThree AI review systems: (i) OpenReviewer for automatic peer review with LLMs; (ii) Papers with Reviews an online paper review platform; and (iii) Reviewer Arena for evaluating reviewers by preferences.\nFour evaluation methods: (i) Human evaluation; (ii) Automatic LLM evaluation; (iii) Automatic LLM prediction of human preferences; and (iv) Automatic discovery of LLM review limitations, using synthesis and analysis to map errors and shortcomings in LLM based reviewing.\nRole playing: Dialogue between LLMs playing different roles in the review process.\nUser feedback: Evaluating quality and trustworthiness.\nThe paper is structured as follows: Section 2  ###reference_### describes our three review systems. Subsequently, Section 3  ###reference_### describes our four methods for evaluating reviews. Section 4  ###reference_### describes the methods used in generating reviews. In Section 5  ###reference_###, we analyze user feedback and address the limitations of our work. Finally, we conclude with our findings and their implications. The supplementary materials consist of 20 Appendices including dataset details, user interface and feedback, prompts, example papers, review questions and scores, evaluation results, and code."

We collect feedback from users in Papers with Reviews. The feedback is on the automated review generated by OpenReviewer for specific papers. The feedback consists of five quantitative questions that evaluate paper reviews (Goldberg et al. 2023  ###reference_b12###) and an open-ended question as described with summary statistics in Appendix C  ###reference_###.\nWe use multiple documents related to the review as LLM context: the previous year\u2019s statistics, reviewer and area chair guidelines, code of ethics and code of conduct, and the formal review form. These venue-dependent documents result in our review score distributions being similar to human distributions and yielding quality reviews using the full range of scores; however, they require yearly updates. A problem with applying the prediction of human preferences to reviews is that different people may prefer different reviews. A Kaggle competition over a dataset of human preferences provides a common ground for prediction. Correcting for human bias helps partially mitigate this gap, as personal preferences are driven by human behavioral bias.\nFuture research will extend our evaluation to examine how authors use and trust LLM reviews. Our analysis of the capabilities of LLMs by classifying and testing various reviewing criteria and types of errors and shortcomings indicates the limits of our current application. These limitations are essential for knowing how to use the application, particularly involving the human reviewer. During this work we devised preventive actions for ethical and transparent use of LLMs in reviewing. Future work will also explore self-evolving LLMs for reviewing that independently learn and improve from experience."

This work evaluates the limitations and capabilities of GPT-4 to review papers and suggest revisions. LLM-generated reviews align well with human reviewers when evaluated by blind human evaluation and an automatic GPT-4 comparison. We present our LLM reviewer system, OpenReviewer, and the associated Papers with the Reviews site. To our knowledge, we are the first to report on such a large-scale empirical evaluation of LLM reviewing.\nUsing human reviews as a baseline, we evaluated value alignment and the process alignment of LLM reviews, i.e., we compared the quality of reviews and the adherence of the reviewing process to conference guidelines and scientific norms of practice. Prior work on LLM academic capabilities suggests that LLMs are now ready for specific reviewing tasks and appear to be more effective for some academic domains and less effective for others (Checco et al. 2021  ###reference_b7###; Schulz et al. 2022  ###reference_b32###; Liu and Shah 2023  ###reference_b19###; Lu et al. 2024  ###reference_b20###). Therefore, we conducted ablation studies and determined the types of errors and shortcomings the LLM can detect and review. When supplied with information about previous editorial decisions, the LLM aligns well with human reviewers. Furthermore, the LLM performs well in detecting specific errors and shortcomings, such as overclaiming, but not others, such as detecting cases in which the authors needed to follow expected norms. We find that iterative design and large-scale empirical evaluation are essential to calibrate the application of LLMs.\nThis work leverages LLMs in the review process, addressing challenges and offering proof-of-concept LLM review tools. We introduce and evaluate systems designed to streamline handling tens of thousands of academic papers, from initial collection to reviewing and evaluation. Our methods offer novel approaches to automating academic reviews, improving upon traditional reviews. Our analysis reveals that the system facilitates a more efficient review process and enhances the accessibility and quality of academic literature for both authors and the broader scholarly community. Using papers from arXiv and open-access Nature, coupled with our methods, shows promise in identifying high-quality papers and emerging research trends. In conclusion, our systems and methods represent the different levels of autonomy in the academic review process, detailed in Appendix Q  ###reference_###, and a step forward in automation improvement. With continued development and community involvement, it holds the potential to transform how academic literature is collected, reviewed, disseminated, and evaluated, making it accessible and valuable to researchers worldwide. We hope that our work paves the way for more efficient, consistent, high-quality reviews, accelerating scientific progress while maintaining responsible conduct of research."

P3 adds the code of ethics (CE) and code of conduct (CC). P4 adds guidelines for the area chair (AC). P5 adds the statistics of the previous year\u2019s conference.\n###figure_3### The human reviewers have an average recommendation score of 5.88, with a standard deviation 1.61. With the context of the entire paper text and the conference review form (P1), the LLM has an average recommendation of 7.21, higher than the human reviewers. The standard deviation of 1.03 is less than that of the human reviewers. Adding the reviewer guide to the context (P2) slightly increases the recommendation score to 7.58. The standard deviation is reduced further, with a more consistent scoring by the LLM. With the addition of the code of ethics and code of conduct to the context (P3), the recommendation score slightly increases to 7.62, similar to P2, and the standard deviation remains the same. After adding guidelines for the area chair (P4), the recommendation score decreases to 4.61, indicating that this context makes the LLM more critical or stringent in its evaluations due to the knowledge of expected outcomes. With the addition of the previous year\u2019s conference statistics (P5), the recommendation score improves and is near the human reviewer\u2019s score. The standard deviation also increases, indicating more variability in the scoring.\nIn summary, LLM contexts P1, P2, and P3 consistently give higher recommendation scores than the human reviewers, suggesting a more positive or lenient view of the papers. P4 context, with the area chair guidelines added, shows a significant decrease in recommendation scores, suggesting these guidelines influence the LLM to be more critical in its evaluations.

The overclaiming category has relatively lower average scores, indicating that the LLM review easily detects these errors and reduces the scores.\n###figure_4### Figure 17  ###reference_### shows the difference in LLM review scores for various error and shortcoming categories compared to the LLM review scores without errors. Figure 16  ###reference_### shows a heatmap using red and green colors to indicate non-positive and positive difference values. The intensity of the color corresponds to the magnitude of the difference between the LLM review score of the original and modified papers. Most of the data points are positive, indicating correct error detection. The categories with the highest detection are overclaiming across most of the papers. Citation issues and Technical errors also stand out, with several papers having higher values, indicating the detection of these errors. Ethical Concerns and Insufficient Ablation Studies have low values or zeros. The heatmap visually summarizes the trustworthiness of reviews across different categories and papers and categories. The LLM is good at finding Overclaiming, Citation Issues, and Theoretical. In contrast, Ethical Concerns and Technical may be overlooked. The ability of the LLM also varies for different papers. The LLM usually give itself a high confidence score in its rating, therefore knowing these difference values for each paper is essential for understanding which parts of the review can be trusted.\n###figure_5### Lack of Baseline Comparisons and Metrics shows significant variability across papers.

We propose different methods for selecting review questions, examining whether they are static or dynamic and to what extent the paper\u2019s content influences them under review. We categorize the review question selection process into four approaches:\nConference or journal-specific fixed questions: Major academic conferences and journals, such as ICLR, ICML, NeurIPS, and CVPR, use predefined review questions. These sets align with the criteria and standards of the corresponding publications, aiming to ensure consistency and fairness in the evaluation process across all submissions.\nType of paper-specific fixed questions: This approach involves curating sets of questions tailored to the type of paper, such as survey, empirical, theoretical, or opinion pieces. By doing so, the review process acknowledges the unique attributes and goals of different types of academic writing, facilitating a more nuanced and appropriate assessment.\nAdaptive choice from a bank of questions based on paper content: We select the most relevant questions from a predetermined pool in this approach. Given the content of a paper and a bank of 40 potential review questions, the LLM identifies the top ten questions that best match the paper\u2019s topic and research questions, customizing the review process to adapt to each submission.\nAdaptive generation of questions based on paper content, journal name, and human reviews: Taking customization a step further, this approach uses the LLM to generate review questions based on the paper\u2019s content, the journal\u2019s name, and the human reviews. Instead of selecting from a pre-existing set, the model analyzes the paper and the human reviews and generates the top ten questions that address the unique aspects of the research. Open-access Nature papers are not subject to fixed review questions, and this method uses the LLM to extract the review questions from the human review answers.\nWe explore these methods to understand how they impact the effectiveness and fairness of the review process. By comparing fixed and adaptive approaches and the influence of paper content on question selection, we demonstrate the potential for LLMs to enhance the quality and relevance of academic paper reviews. We keep updated versions of the latest conference documents, including review forms, reviewer guidelines, code of ethics and conduct, area chair guides, and previous years\u2019 statistics. This ensures that the review generation capabilities align better with the most recent academic standards, expectations, and guidelines."

We perform hyper-parameter tuning to optimize both training and inference processes, using the Optuna (Bergstra et al. 2011  ###reference_b5###) AutoML hyperparameter optimization tool.\nWe generate three datasets by data augmentation applied to the original competition training dataset: (i) The first augmented dataset is created by paraphrasing the original prompts while keeping the associated responses unchanged. We use Anthropic\u2019s prompt generation tool (McKay 2024  ###reference_b21###), which creates a step-by-step plan for paraphrasing the prompts and elevates tedious prompt engineering efforts.

A value is assigned to each operation to control the extent of modification (Wei and Zou 2019  ###reference_b38###). The values range from 0 (no modification) to 1 (total modification), and are randomly selected for each operation applied to the entries in the training set.

Problems with solely using LLMs include evaluation bias, the risk of LLMs favoring results from similar LLMs, potential bias against specific user groups, misinformation, and hallucinations. Our goal is to avoid such biases and ensure factual accuracy. We propose combining humans and LLMs for evaluation by understanding the broad spectrum between human evaluation and full automation by LLMs. Currently, humans are the sole reviewers without any AI interference. It is common practice for humans to maintain complete control while being supported by AI which summarizes and highlights paper and review texts. LLMs may help humans make decisions by generating summaries for human evaluation. Beyond summaries, humans and LLMs may collaborate by having each make decisions they are good at, such as by role-playing and dialogue.\nMoving closer to automation is achieved by humans in the loop, having humans prefer between automated evaluations or decisions or having a human verify and accept or reject an automated decision. Role-playing and dialogue may consider LLMs as crowd workers to be supervised by humans. Finally, fully automated reviewing may be beneficial in automating the entire scientific process, but it is unsuitable for the current academic review process."

+    "abstract": "In 5G networks, network slicing has emerged as a pivotal paradigm to address diverse user demands and service requirements. To meet the requirements, reinforcement learning (RL) algorithms have been utilized widely, but this method has the problem of overestimation and exploration-exploitation trade-offs. To tackle these problems, this paper explores the application of self-play ensemble Q-learning, an extended version of the RL-based technique. Self-play ensemble Q-learning utilizes multiple Q-tables with various exploration-exploitation rates leading to different observations for choosing the most suitable action for each state. Moreover, through self-play, each model endeavors to enhance its performance compared to its previous iterations, boosting system efficiency, and decreasing the effect of overestimation.\nFor performance evaluation, we consider three RL-based algorithms; self-play ensemble Q-learning, double Q-learning, and Q-learning, and compare their performance under different network traffic. Through simulations, we demonstrate the effectiveness of self-play ensemble Q-learning in meeting the diverse demands within 21.92% in latency, 24.22% in throughput, and 23.63% in packet drop rate in comparison with the baseline methods. Furthermore, we evaluate the robustness of self-play ensemble Q-learning and double Q-learning in situations where one of the Q-tables is affected by a malicious user. Our results depicted that the self-play ensemble Q-learning method is more robust against adversarial users and prevents a noticeable drop in system performance, mitigating the impact of users manipulating policies.",

In this context, ultra-reliable low latency communication (URLLC), enhanced mobile broadband (eMBB), and massive machine-type communications (mMTC) are fundamental use cases [2  ###reference_b2###] which demand low-latency, high throughput, and supporting a massive number of connected devices, respectively. Using the network slicing strategy, 5G networks can address the requirements of URLLC, eMBB, and mMTC seamlessly in various slices [2  ###reference_b2###]. As a means of optimizing these slices\u2019 performance, machine learning-based (ML-based) algorithms, in particular reinforcement learning (RL), present promising solutions. Q-learning, as a type of RL, empowers algorithms to make intelligent decisions by learning from interactions with the environment. Furthermore Q-learning adapts to dynamic network conditions acquires optimal strategies over time, and provides efficient resource allocation [3  ###reference_b3###].\nWhile the RL-based methods have a considerable effect on meeting the requirements of network slicing, they face some challenges such as overestimation bias, slow learning, complexity in large-scale network scenarios, and the need for extensive training data [4  ###reference_b4###]. In determining optimal resource allocations for diverse slices, the RL algorithm encounters difficulty with the exploration-exploitation trade-off [6  ###reference_b6###]. The high-dimensional state spaces inherent in network slicing, representing various service requirements and dynamic network conditions, also lead to the challenge of effectiveness in complex environments [4  ###reference_b4###]. To address these weaknesses, appropriate modifications to Q-learning are necessary to increase the efficiency and adaptability of resource allocation [7  ###reference_b7###].\nAddressing the challenges raised by Q-learning for resource allocation in network slicing, alternative approaches such as double Q-learning, deep Q-learning (DQN), and double DQN [8  ###reference_b8###, 9  ###reference_b9###] emerge as promising solutions.\nBy utilizing two separate value functions for action selection and evaluation, double Q-learning mitigates the algorithm\u2019s exploration-exploitation trade-off, thereby improving its ability to determine optimal resource allocations [10  ###reference_b10###]. DQN uses neural networks to handle high-dimensional state spaces, which provides a scalable solution for network slicing [11  ###reference_b11###].\nBeyond these methods, ensemble Q-learning, which employs multiple Q-tables, is proposed to address overestimation bias and the handling of complex interactions in Q-learning [12  ###reference_b12###].\nWhile double Q-learning, DQN, and ensemble Q-learning significantly contribute to mitigating challenges in Q-learning, there remain unresolved issues related to efficient exploration and adaptability in dynamic environments and heterogeneous objectives optimization. Moreover, their susceptibility to adversarial users is related to their concentration on the current state and experience for action selection. To tackle these challenges, in this paper self-play ensemble Q-learning is proposed, offering a solution that uses diverse learning strategies through iterative interactions with the agent\u2019s previous versions, in the context of resource allocation. Different from existing algorithms such as double Q-learning and Q-learning according to our simulation results, self-play ensemble Q-learning provides more efficient, scalable, and adaptive allocation strategies that address the limitations of Q-learning when applied to evolving and complex scenarios. While RL-based methods have a considerable effect on improving network slicing performance [17  ###reference_b17###], they are quite vulnerable to malicious users [15  ###reference_b15###]. In this paper, to evaluate the robustness of methods against malicious users, such as double Q-learning and self-play ensemble Q-learning, we considered a scenario in which one of the tables is affected by a malicious user who chooses the action that leads to the lowest Q-value. While the double Q-learning algorithm performance drops considerably, self-play ensemble Q-learning, due to the agent\u2019s interaction with its previous steps and using several Q-tables, the method is more robust against adversarial users who have malicious aims in the system."

This adaptive approach enhances the efficiency and responsiveness of the network slicing, ensuring that resources are allocated optimally to meet various slice demands, and\noffering improved performance, reliability, and adaptability to different applications [14  ###reference_b14###]. Q-learning proves to be a valuable approach to resource allocation in network slicing and provides an adaptive and intelligent mechanism for allocating resources effectively [17  ###reference_b17###].\nWhile Q-learning is a powerful tool for 5G communications,\nit has several drawbacks such as the tendency to overestimate Q-values, exploration-exploitation trade-off, and slow learning in large state spaces, leading to suboptimal decision-making and slower convergence [4  ###reference_b4###]. In [13  ###reference_b13###], a DQN-based method is proposed for resource allocation to approximate Q-values, enabling the algorithm to handle more complex state-action spaces. In [7  ###reference_b7###], an ensemble Q-learning is employed by multiple Q-learners, aggregating their predictions to improve overall performance and robustness. In [12  ###reference_b12###], an ensemble bootstrapped Q-learning method is proposed as a bias-reduced algorithm, extending double Q-learning to ensembles to mitigate both over-estimation and under-estimation biases, demonstrating superior performance in deep reinforcement learning (DRL). In [7  ###reference_b7###], an adaptive ensemble Q-learning method is proposed to address the overestimation issue in Q-learning by adjusting ensemble size based on upper and lower bounds of estimation bias, which demonstrates an improvement in model learning. While ensemble Q-learning enhances robustness and promotes continuous improvement, it encounters difficulties dealing with overestimation bias, leading to suboptimal decision-making. Additionally, the interdependence of Q-values across different models limits the efficient learning of multiple models simultaneously.\nAs a solution, self-play ensemble Q-learning is proposed, in which agents interact with themselves and the environment simultaneously by playing against previous versions of themselves, leading to learning and improvement action selection, rather than exploring random actions.\nThese advancements in Q-learning variants demonstrate a collective effort to overcome its limitations, offering more effective and adaptive resource allocation strategies in dynamic and complex environments of network slicing for 5G and beyond. While ML algorithms have considerable effects on improving the quality of services and meeting requirements, they have some issues related to the exploration-exploitation trade and they are also vulnerable to malicious users [15  ###reference_b15###]. Malicious users attempt to perturb the system and degrade its performance by altering the policy for resource allocation [15  ###reference_b15###] or introduce interference to the signal, leading to signal degradation in Q-learning scenarios [16  ###reference_b16###]. The goal of this paper is to employ self-play ensemble Q-learning for the first time to enhance resource allocation performance in network slicing and improve robustness against adversarial users."

As illustrated in Fig. 1  ###reference_###, a two-step resource allocation scheme is employed on a gNodeB (eNB). The eNB is equipped with a mobile edge computing (MEC) server which provides the capability of offloading tasks to a cloud server. During the inter-slice phase, the eNB intelligently distributes radio resources among two slices. Subsequently, these allocated resources are utilized within each specific slice during the intra-slice phase. The primary objective is to assign radio resources which refers to time-frequency resource blocks between two slices to meet the latency and throughput requirements of URLLC and eMBB slices.\n###figure_1### For meeting the requirements of slices, decreasing the latency is pivotal which is evaluated by the equation below:\nwhere  is the transmission delay,  is the re-transmission delay,  is the queuing delay, and  is the processing delay in the MEC server.\n is affected by the size of packets sent by a user equipment (UE) and the link capacity between UE  and its connected eNB , denoted as .

The readers are referred to [18  ###reference_b18###] for details of O-RAN architecture. To meet UEs requirements, the URLLC slice seeks to reduce latency, while the eMBB slice aims to increase throughput. Given these considerations, the allocation of resource blocks could be formulated as follows:\nwhere  and  are the weighting factors of eMBB and URLLC slices to make throughput and latency comparable.  represent the throughput of the UE  in the eMBB slice of eNB .  refers to the target delay of the URLLC slice, and  identifies the UE latency within the URLLC slice of eNB .  and  are indicators of how many eMBB and URLLC slices are available in eNB .

For using the Q-learning algorithm for RB allocation, the following components of the Markov decision process (MDP) are taken into account for the agent:\nStates: States for the agent is , indicating the number of eMBB and URLLC tasks in the queue.\nAction: The agent has access to the radio resources, and its action is dictated by the number of resource blocks allocated to the eMBB and URLLC slices. The action set is defined by .\nReward: The reward function, as defined in Eq. LABEL:eqn:reward, is calculated based on the average throughput and delay experienced by the eMBB and URLLC slices.\nQ-learning involves updating the Q-values based on the maximum Q-value of the next state. Furthermore, Q-learning focuses on updating Q-values based on the agent\u2019s interactions with the environment, and the update rule considers the immediate reward obtained from taking an action in a given state and the estimated future rewards. However, this can result in an overestimation of Q-values, especially when the eNB has not sufficiently explored the environment. Furthermore, Q-learning has the challenges of hyperparameter fine-tuning. Foremost, adversarial agents have a significant and detrimental impact on Q-learning performance, leading to substantial degradation. For this reason, the self-play ensemble Q-learning algorithm has been suggested as a method for handling these challenges and improving the RB allocation."

+            "text": "The ensemble Q-learning approach involves maintaining several Q-tables, denoted as , where  represents the number of tables. In the considered approach, decisions from multiple Q-tables are aggregated using a majority voting (MV) mechanism. Each agent provides its Q-values for a specific state-action pair, and the action with the majority of votes is selected as the final decision.  represent the Q-value predicted by the -th Q-learning agent for state  and action . The MV function can be defined as Algorithm 1 where  is the number of Q-tables which is equal to 3, and  is the selected action based on MV. While increasing the number of Q-tables improves the method\u2019s exploration capabilities, it also increases the method\u2019s complexity and energy consumption. Therefore, we select  to balance these factors.\nWhen implementing MV for Q-learning, it\u2019s crucial to address ties when there is no clear majority. A random selection strategy is employed for this purpose. It must be noted that the weights of all considered  are assumed to be the same, then the system is affected by all of them equally.\nEnsemble Q-learning, while effective in some scenarios, faces several challenges that can hinder its performance in dynamic network slicing environments. One of the challenges is its exploration, which increases the probability of convergence to local optima. To address this, self-play ensemble Q-learning considers its previous values, always striving to select the best action encountered thus far and avoiding getting stuck in local optima. Additionally, handling complex state spaces poses a difficulty for ensemble Q-learning. Self-play ensemble Q-learning introduces mechanisms to better understand and learn from all Q-values by the explicit consideration of the agent\u2019s interactions with its past versions. Furthermore, the Q-values are updated not only based on the immediate rewards from the environment but also the outcomes of self-play experiences against its past versions. The update involves a weighted average of the current Q-values and the past versions of Q-values, which are calculated by the equation below.\nwhere the weight  determines how much influence the past version has on the current Q-values. This ensures a balance between incorporating new experiences from the current episode and leveraging knowledge from the past version. Using this equation leads to observing the performance of the current agent\u2019s observations from the environment against its previous strategies and controlling the influence of the past versions on the updating of current Q-values. This part of the algorithm focuses on enhancing the current agent\u2019s Q-values by considering its past strategies, allowing it to adapt and improve over time through self-play. For each , iterate through all  in the Q-table.\nThe self-play ensemble Q-learning method can improve the learning process in the following ways:\nMonitoring: In the ensemble part, the agent attempts to consider various aspects of the system, choosing different actions in each state to receive diverse rewards. This process helps the agent generate diverse experiences.\nAdaptability: Self-play enables the agent to adapt its strategy over time. As it encounters different situations, it learns to respond to a variety of states, making it more robust and adaptable.\nContinuous Improvement: The agent improves its policies and strategies by repeatedly playing against its current or past versions, refining its decision-making process, discovering new tactics, and enhancing performance.\nReduced Dependency on External Data: Since the agent generates its training data by self-play, it becomes less dependent on external data. This is useful when external data is poisoned, limited, or not readily available.\nExploration of Strategies: During self-play, the agent explores various strategies, enhancing its understanding of the environment and potentially discovering optimal or near-optimal policies.\nThis process allows the current agent to learn from its recent experiences in the network slicing system, and also its history of playing against earlier versions. It introduces a form of memory or hindsight learning, potentially improving the agent\u2019s strategy over time.

More specifically, we first prove an FTISS Lyapunov theorem for a class of infinite-dimensional systems, namely, the existence of an FTISS Lyapunov functional (FTISS-LF) implies the FTISS of the system, and then, provide a sufficient condition for ensuring the existence of an FTISS-LF for a class of abstract infinite-dimensional systems under the framework of compact semigroup theory and Hilbert spaces. As an application of the FTISS Lyapunov theorem, we verify the FTISS for a class of parabolic PDEs involving sublinear terms and distributed in-domain disturbances.

+            "text": "Originally introduced by Sontag in 1989 [1  ###reference_b1###], the notion of input-to-state stability (ISS) provides a powerful tool for characterizing the influence of external inputs on the stability of\nfinite-dimensional systems.\nThe ISS theory becomes rapidly one of the pillars in the nonlinear and robust control [2  ###reference_b2###, 3  ###reference_b3###, 4  ###reference_b4###, 5  ###reference_b5###] and has a wide range of applications in various fields, e.g., robotics [6  ###reference_b6###], aerospace engineering[7  ###reference_b7###], transportation[8  ###reference_b8###], etc.\nRoughly speaking, if a system is ISS, then it is asymptotically stable in the absence of external inputs while keeping certain robust properties, such as \u201cbounded-input-bounded-state\u201d, in the presence of external inputs. Especially, the state of the system should be eventually small when the inputs are small.\nExtending the ISS theory of finite-dimensional systems to infinite-dimensional systems started around 2010 [9  ###reference_b9###, 10  ###reference_b10###] and has achieved significant progress in the past decade; see, e.g., [11  ###reference_b11###, 12  ###reference_b12###, 13  ###reference_b13###, 14  ###reference_b14###, 15  ###reference_b15###, 16  ###reference_b16###, 17  ###reference_b17###] for ISS-Lyapunov characterizations for abstract infinite-dimensional systems; [10  ###reference_b10###, 18  ###reference_b18###, 19  ###reference_b19###, 20  ###reference_b20###, 21  ###reference_b21###, 22  ###reference_b22###, 23  ###reference_b23###, 24  ###reference_b24###, 25  ###reference_b25###, 26  ###reference_b26###] for the ISS assessment of partial differential equations (PDEs) with different types of disturbances; [18  ###reference_b18###, 25  ###reference_b25###, 27  ###reference_b27###, 28  ###reference_b28###, 29  ###reference_b29###, 30  ###reference_b30###] for the input-to-state stabilization of PDEs under backstepping control, and [31  ###reference_b31###, 32  ###reference_b32###, 33  ###reference_b33###] for the application of ISS to\nPDEs arising in multi-agent control, the railway track model, and power tracking control, just to cite a few.\nIt is worth mentioning that in [34  ###reference_b34###, 35  ###reference_b35###] the authors introduced a new stability concept, which is stronger than the ISS, to tackle finite-time control problems (see [36  ###reference_b36###, 37  ###reference_b37###, 38  ###reference_b38###, 39  ###reference_b39###, 40  ###reference_b40###, 41  ###reference_b41###, 42  ###reference_b42###, 43  ###reference_b43###]) for finite-dimensional nonlinear systems with uncertainties, namely, the finite-time input-to-state stability (FTISS). More specifically, taking into account the properties of FTS and ISS, the FTISS of a system requires that in the absence of external inputs the state of the system should reach equilibrium within a finite time, while in the presence of external inputs the state can reach a given bounded region in finite time [34  ###reference_b34###, 35  ###reference_b35###, 44  ###reference_b44###, 45  ###reference_b45###]. Moreover, the state should be small when the inputs are small.\nTherefore, the notion of FTISS provides a refined characterizations for the robust stability of finite-dimensional systems, which plays a key role in the study of finite-time stability and stabilization of finite-dimensional nonlinear systems (see [34  ###reference_b34###, 35  ###reference_b35###, 46  ###reference_b46###, 47  ###reference_b47###]) and has attracted much attention in the past few years [44  ###reference_b44###, 45  ###reference_b45###, 47  ###reference_b47###, 48  ###reference_b48###, 49  ###reference_b49###]. Especially, the FTISS Lyapunov theorem, which states that the existence of an FTISS Lyapunov functional (FTISS-LF) implies the FTISS of the system, has been proved for certain finite-dimensional systems [34  ###reference_b34###, 35  ###reference_b35###, 44  ###reference_b44###, 45  ###reference_b45###, 46  ###reference_b46###, 47  ###reference_b47###].\nThe first attempt to extend the concept of FTISS to infinite-dimensional systems is due to [50  ###reference_b50###], where, as a special case of FTISS, the notion of prescribed-time input-to-state stability (PTISS) was extended to infinite-dimensional systems. Moreover, a PTISS Lyapunov theorem was proved and a sufficient condition for the existence of a PTISS Lyapunov functional was provided for a class of infinite-dimensional systems under the framework of Hilbert spaces [50  ###reference_b50###]. Unlike the FTISS, for which the settling time may depend on the initial data and be unknown in advance, the PTISS indicates that the system can be stabilized within a prescribed finite time, regardless of its initial data. Especially, as addressing the PTISS of finite-dimensional systems [51  ###reference_b51###], by introducing a monotonically increasing function  with a prescribed finite time  to the structural conditions of FTISS-LFs, it is straightforward to prove the PTISS for a class of infinite-dimensional systems or parabolic PDEs with time-varying reaction coefficients having a form of  by using the Lyapunov method [50  ###reference_b50###].\nIt is worth noting that for infinite-dimensional systems, studying the FTISS in a generic case where the stabilization time is unknown in advance and may be dependent of initial data, i.e., the FTISS without prescribing the settling time, is indeed more challenging compared to the case of PTISS, and no relevant results have yet been reported in the existing literature.\nThe main obstacle in addressing the FTISS for infinite-dimensional systems may lie in verifying sufficient conditions for the existence of an FTISS-LF. In particular, for specific PDEs, it is difficult to validate the effectiveness of a Lyapunov candidate in the FTISS analysis due to the fact that sublinear terms are usually involved and cannot be easily handled. In addition, compared to the PTISS analysis of infinite-dimensional systems, for which strongly continuous semigroup (-semigroup) generated by bounded linear operators is often used to ensure the well-posedness, as shown in Section 2.3  ###reference_### and 3  ###reference_### of this paper, even for parabolic PDEs, additional properties of -semigroup are needed for proving the well-posedness of the corresponding abstract systems due to the appearance of non-Lipschitz continuous terms when the FTISS is considered. This also represents a challenge.\nThe aim of this work is to study the FTISS for infinite-dimensional systems without prescribing the settling time and provide tools for establishing the FTISS for certain nonlinear infinite-dimensional systems. In particular, as a first attempt in addressing the FTISS for PDEs, we show how to verify the well-posedness based on the application of the compact semigroup theory and to use the interpolation inequality to overcome the difficulties in verifying the structural conditions of Lyapunov functionals for a class of parabolic PDEs with sublinear terms and distributed in-domain disturbances. Overall, the main contribution of this work include:\nextending the notion of FTISS for finite-dimensional systems to infinite-dimensional systems and proving a Lyapunov theorem, which states that the existence of an FTISS-LF implies the FTISS of the system;\nproviding a sufficient condition to guarantee the existence of an FTISS-LF for certain nonlinear infinite-dimensional systems under the framework of compact semigroup theory and Hilbert spaces, thereby providing tools for stability analysis of infinite-dimensional systems;\nproving an interpolation inequality, which paves the way to assess the FTISS for PDEs, and verifying the sufficient condition for the existence of an FTISS-LF for a class of parabolic PDEs with sublinear terms and distributed in-domain disturbances.\nIn the rest of the paper, we introduce first some basic notations used in this paper.\nIn Section 2.1  ###reference_### and 2.2  ###reference_###, we introduce the notions of FTISS and FTISS-LF and prove the FTISS Lyapunov theorem for infinite-dimensional systems under a general form, respectively. In Section 2.3  ###reference_###, we provide a sufficient condition that ensures the existence of an FTISS-LF for certain infinite-dimensional nonlinear systems under the framework of compact semigroup theory and Hilbert spaces. In Section 3  ###reference_###, considering the application of FTISS Lyapunov theorem, we verify the FTISS for a class of parabolic PDEs with sublinear terms and distributed in-domain disturbances. More specifically, we first prove the well-posedness by using the compact semigroup theory in Section 3.1  ###reference_###. Then, we prove an interpolation inequality and use it to verify the FTISS for the considered PDEs in Section 3.2  ###reference_###. We also conduct numerical simulations to illustrate the obtained theoretical results in Section 3.3  ###reference_###. Finally, some conclusion remarks are given in Section 4  ###reference_###."

In particular, we demonstrated the construction of Lyapunov functionals tailored for assessing the FTISS for a class of infinite-dimensional nonlinear systems under the framework of compact semigroup theory and Hilbert spaces, and verified the FTISS for parabolic PDEs with sublinear terms by using an interpolation inequality. Numerical results were presented to illustrate the obtained theoretical results. It is worth mentioning that designing feedback controls to achieve the FTISS for parabolic PDEs remains a challenging subject that will be considered in our future work."

+    "title": "Evaluating Image-Based Face and Eye Tracking with Event Cameras",
+    "abstract": "Event Cameras, also known as Neuromorphic sensors, capture changes in local light intensity at the pixel level, producing asynchronously generated data termed \u201cevents\u201d. This distinct data format mitigates common issues observed in conventional cameras, like under-sampling when capturing fast-moving objects, thereby preserving critical information that might otherwise be lost. However, leveraging this data often necessitates the development of specialized, handcrafted event representations that can integrate seamlessly with conventional Convolutional Neural Networks (CNNs), considering the unique attributes of event data. In this study, We evaluate event-based Face and Eye tracking. The core objective of our study is to showcase the viability of integrating conventional algorithms with event-based data, transformed into a frame format, while preserving the unique benefits of event cameras. To validate our approach, we constructed a frame-based event dataset by simulating events between RGB frames derived from the publicly accessible Helen Dataset. We assess its utility for face and eye detection tasks through the application of GR-YOLO \u2013 a pioneering technique derived from YOLOv3. This evaluation includes a comparative analysis with results derived from training the dataset with YOLOv8. Subsequently, the trained models were tested on real event streams from various iterations of Prophesee\u2019s event cameras and further evaluated on the Faces in Event Stream (FES) benchmark dataset. The models trained on our dataset shows a good prediction performance across all the datasets obtained for validation with the best results of a mean Average precision score of 0.91. Additionally, The models trained demonstrated robust performance on real event camera data under varying light conditions.",

This tracking technology is pivotal in detecting signs of fatigue, distraction, or impairment, necessitating a continuous stream of visual data, which is often unfeasible with traditional frame-based cameras. Other challenges include addressing scale variations as faces move closer or further from the camera, managing temporal dependencies between consecutive frames, accurately detecting faces under occlusions caused by rapid movements, and accounting for motion-induced shape deformations [48  ###reference_b48###, 5  ###reference_b5###].\nEvent cameras (ECs) on the other hand, respond to changes in brightness to produce a continuous stream of data of asynchronous nature called events. ECs capture high-speed motion with very low latency and minimal motion blur. Events in an EC are represented by a stream of variable data points, each indicating a change in intensity at a specific pixel location at a given time. An event is therefore represented as a tuple, , where  are the spatial coordinates,  is the timestamp, and  is the polarity. The polarity is used to indicate changes in pixel intensity. That is, for ,  indicates a decreasing change while 1 indicates an increasing change. ECs offer many advantages over traditional cameras including High Dynamic Range (140 dB versus 60 dB), High Temporal Resolution and Low Latency allowing them to capture and process visual information in real-time, with minimal delay making them ideal for applications that require fast, yet accurate visual feedback.\nHowever, utilizing ECs for such tasks introduces unique challenges due to the distinct nature of events. It is a common practice in the domain of event-based vision to develop specialized algorithms with hand-crafted event representations to accommodate the use of this data. However, it is important to bridge the gap between this novel data type and the established paradigms of computer vision, which predominantly utilize Convolutional Neural Networks (CNNs) that process standard video frames [33  ###reference_b33###]. In our work, we aim to highlight methods of representing events in a format accepted by existing deep learning approaches, specifically an image-based representation while preserving the unique advantages of event cameras. We do this by optimizing the frames generated during motion simulation from static images by maximizing the number of events produced and event-frame accumulation with Temporal Binary Representation (TBR) [21  ###reference_b21###]. This study is inspired from the work of Ryan et al. [36  ###reference_b36###]. However, our methodology diverges from the previous approach in three fundamental aspects:\nWe generate motion from the Helen Dataset by simulating planar motion from images placed in front of a camera in 6-Degrees of Freedom (DOF), as opposed to cropping an image and shifting the crop along the  and  axes.\nBeyond employing an event simulator to convert RGB videos into events, we accumulate events into binary frames and aggregate these frames into a single frame. This process enhances the density and quality of the simulated frames derived from the original RGB frames, enriching better simulation of events.\nFinally, we carry out a detailed comparison, examining the performance of state-of-the-art models such as YOLOv8 and contrasting these results with those achieved by the GR-YOLO model [36  ###reference_b36###]. This evaluation is performed using simulated event datasets and real event datasets, thereby affirming the effectiveness and relevance of our proposed methods.\nThrough this comparison, we aim to demonstrate the improvements our approach introduces to the domain and verify its usefulness in improving the adaptability and efficiency of deep learning models for processing the distinct data produced by event cameras.\nThe paper is structured as follows: Literature Review, Dataset, Event Representation, Network Architecture, Training, Results and concluding remarks. We demonstrate the effectiveness of the proposed methodologies and show that training on these datasets generalizes well to real-world examples. An overview of the proposed methodology is illustrated in Fig. 1  ###reference_###.\n###figure_1###"

These characteristics among others have been demonstrated to offer promising applications in face analysis such as gaze estimation [26  ###reference_b26###, 35  ###reference_b35###], face pose alignment [37  ###reference_b37###], yawn detection  [23  ###reference_b23###], emotion recognition [6  ###reference_b6###, 3  ###reference_b3###] etc. However, these tasks have not achieved widespread attention within the domain of event-based vision. This is primarily due to the absence of event-based datasets that are readily applicable for face tracking.\nStudies have revealed different approaches to the use of ECs for face tracking [5  ###reference_b5###].\nThe first works on ECs for face tracking leveraged different representations and algorithms that could fit these representations. Barua et al. [4  ###reference_b4###], utilised a patch-based sparse dictionary generated from event data with the K-SVD algorithm, reconstructed high-intensity images from these streams and employed the Viola-Jones algorithm and random forest as a learning scheme for face detection. Lenz et al. [24  ###reference_b24###] introduced the first purely event-based approach for face detection and tracking, capitalizing on the high temporal resolution offered by an EC to identify the distinct signatures of eye blinks for face detection. Ramesh et al. [32  ###reference_b32###] introduced a novel event-based feature learning method using kernelized correlation filters (KCF) within a boosting framework. Unlike previous works that relied on handcrafted feature descriptors, the proposed approach reformulates KCFs to learn face representations directly from data collected using ECs stemming from their capacity to sense asynchronous pixel-level brightness at a microsecond time-scale. Liu et al. [27  ###reference_b27###] proposed a method for face detection by partitioning event streams into spatial-temporal volumes and introduce a network comprising of a translation-invariant backbone, a Shift Feature Pyramid network (FPN), and a shift context module to handle the spatial-temporal nature of event data aiming for accurate and resource-efficient driver face detection.\nIn contrast to prior works, Current research have focused on representing events in a format understood by existing computer vision algorithms [33  ###reference_b33###].

However, recent attention has shifted towards ECs due to their asynchronous data presentation, eliminating the need for fixed frame rates. ECs offer low latency, enabling immediate event reporting with high temporal precision, making them particularly suitable for tracking eyes in scenarios involving rapid motion.\nFoundational works by Angelopoulos et al. [1  ###reference_b1###] used traditional image processing and statistical methods for segmenting eye regions effectively. Building on this, Feng et al. [18  ###reference_b18###] introduced an innovative Auto ROI algorithm that dynamically predicts eye ROIs to enhance tracking efficiency. Further, Li et al. [25  ###reference_b25###] adopted an event-driven approach, processing event streams into frames and employing a low-latency CNN with an event-based ROI system for accurate pupil detection.\nIn contrast, a series of studies leveraged neural networks to address the unique challenges posed by sparse event data. Chen et al. [13  ###reference_b13###] proposed a Change-Based Convolutional Long Short-Term Memory (CB-ConvLSTM) model for precise pupil tracking. Bonazzi et al. [10  ###reference_b10###] utilized a Spiking Neural Network (SNN) trained directly on event data, and Yang et al. [49  ###reference_b49###] applied a U-Net based network alongside frame interpolation techniques to produce high frame rate videos from event streams for detailed pupil segmentation.\nRecent studies have introduced more specialized techniques. Stoffregen et al. [42  ###reference_b42###] focused on detecting corneal glint using a coded differential lighting system to improve specular reflection detection in a purely event-based manner. Zhang et al. [51  ###reference_b51###] proposed event-based frame interpolation, and a suite of modules for feature extraction and temporal feature fusion, particularly effective during blinking motions. Lastly, Zhao et al. [52  ###reference_b52###] employed polynomial regression to localize pupil centroids and accurately identify the Point of Gaze from event streams.\nQuite recently, a number of studies have emerged on the use of ECs for eye tracking as a result of the introduction of the Event-based Eye Tracking(EET) challenge [46  ###reference_b46###]. The CVPR AI in Streaming (AIS) EET Challenge on Kaggle focused on the use of data from ECs for eye tracking. In our study, we do not review individual studies due to constraints on length. It is however worth noting that most participants utilised frame based representations with already existing deep learning algorithms such as CNNs,GRU and LSTMs, demonstrating the significance of our evaluation. These developments showcase the diversification and progression of techniques in event-based eye tracking, from traditional methodologies to novel approaches tailored to exploit the full capabilities of ECs. A more comprehensive survey of the solutions presented is provided in the associated survey of the challenge [46  ###reference_b46###]."

Most research utilizes locally sourced or simulated datasets [38  ###reference_b38###, 8  ###reference_b8###]. Publicly available options like the Neuromorphic Event-based Facial Expression Recognition dataset [7  ###reference_b7###] offer RGB and event streams for facial expression recognition but lack face and eye location annotations of the event stream. Directly applicable datasets for face and eye tracking are scarce, with the recent Faces in Event Stream (FES) dataset [9  ###reference_b9###] being a notable exception. Despite providing event streams and bounding boxes, FES lacks eye annotations, necessitating manual annotation efforts.\nA promising solution involves using event simulators. For instance, Ryan et al. [36  ###reference_b36###] developed the Neuro-morphic Helen synthetic dataset by converting the Helen Facial Landmarks Dataset, which comprises 2,300 internet-sourced images with landmark annotations, into an event format. This conversion involved simulating camera motion across the images and applying random augmentations before feeding the resulting videos into an event simulator that transforms RGB videos into events [20  ###reference_b20###].\nA main advantage in the use of the Helen dataset for this task is the different facial features present in the dataset that enables us to train a model robust to a wide variety of facial features and occlusions such as glasses, headwear, etc.\nReproducing the Neuro-morphic Helen Dataset reveals challenges in how Event Simulators mimic real-world event generation. These simulators often rely on discrete time intervals to model events, deviating from the continuous flow of real-world dynamics [5  ###reference_b5###, 8  ###reference_b8###]. To address this issue, more sophisticated algorithms are required that can approximate continuous real-world processes while balancing computational feasibility.\nTo generate motion similar to that of real Prophesee ECs [31  ###reference_b31###], we utilized the PlanarMotionStream object of the Metavision software suite [30  ###reference_b30###]. This software simulation operates in a manner that is similar to the way Prophesee event cameras function, ensuring that the events generated are similar to those obtained from real Prophesee ECs. The PlanarMotionStream class creates a simulated stream of images that depict how a static picture would appear if observed through a camera undergoing planar motion in front of it.\nPlanarMotionStream is designed to create a realistic simulation of 6-DOF (Degrees of Freedom) motion for a given image. The class generates a sequence of frames, each representing the image as viewed from a slightly different camera pose. This is achieved through the application of homographic transformations that preserve straight lines and are widely used for tasks such as image stitching and perspective correction. The class is initialized with several parameters with the ones of utmost importance being; infinite - a boolean flag determining the border handling method (mirrored or constant), pause_probability - probability that the camera motion will pause at each frame, max_frames - the maximum number of frames to stream, and a method -\nget_relative_homography which computes the homography between two camera poses. Given a specific time step, it retrieves the rotation and translation vectors for the specified time step and the current iteration, and then calculates the relative homography using these vectors. This method is useful for understanding the transformation between any two frames in the sequence.\nWe set  and  contributing to a more realistic simulation. This allows a smooth motion that does not lead to a rapid shift in faces from the original position of the facial features in the RGB image. Smoother transitions maintain the continuity of facial features, which is crucial for accurate event representation. This process aids in solving the problem of under-sampling as more interpolated frames are generated to produce a continuous stream of events that accounts for every pixel value in the final frames used for training. Once the motion-generated videos based on a fixed frame rate have been created, we use the event simulator object from the same SDK to convert these videos into event dictionaries for further preprocessing. An example is seen in Fig. 2  ###reference_###.\n###figure_2###"

For object tracking there is a need to transform event data into a representation accepted by CNNs. In recent years, there have been several hand crafted event-representations proposed. In this study, instead of using hand-crafted temporal representations, we employed an image-based representation to enable training with existing object detection models. This methodology involves converting the simulated event streams into two-dimensional frames, which are directly interpretable by CNNs. The approach also focuses on preserving key information from the events, such as polarity, timestamps, and in some cases, event count.\nWe leveraged the Temporal Binary Representation (TBR) method of aggregating events [21  ###reference_b21###]. TBR employs a binary method for processing events in pixels over a fixed time window, . A binary representation is created for each pixel indicating the presence  or absence  of an event during the accumulation time. Finally, these binary values are stacked into a tensor, with each pixel represented as a binary string. This string is then converted into a decimal number, allowing the representation of  consecutive accumulation times in a single frame without information loss, as shown in Fig. 3(a)  ###reference_sf1###. The frame is normalized by dividing its values by . Fig. 3(b)  ###reference_sf2### represents 1 binary frame from several binary frames generated and Fig. 3(c)  ###reference_sf3### shows the resulting accumulated frames. This allows us to encode temporal information\ndirectly into pixel values, which are then interpreted by CNNs.\n###figure_3### ###figure_4### ###figure_5### TBR offers significant advantages over traditional event aggregation methods. By reducing the memory requirement by a factor of , it minimizes the data processed by computer vision algorithms. This efficiency enables applications under time constraints and allows for capturing events at finer temporal scales without increasing the number of frames."

A notable deviation in our approach is eschewing voxel grids, typically employed in discrete time bins, and instead leveraging frame-based representations. This decision simplifies the model\u2019s interface with existing architectures and enhances adaptability and applicability in real-world scenarios. The GR-YOLO architecture, shown in  Tab. 1  ###reference_###, integrates the YOLOv3 Tiny model with the addition of a Gated Recurrent Unit (GRU). The network comprises several key layers, each contributing uniquely to the effectiveness of the model.\nThe GRU is particularly beneficial in scenarios where sequences of frames are involved. By retaining information from previous frames, the GRU enables the model to understand motion and changes over time, leading to more accurate and consistent tracking of faces and eyes. This backward propagation of information significantly enhances the model\u2019s performance compared to the Tiny-YOLOv3 model without a GRU. YOLO Heads are responsible for predicting bounding boxes and class probabilities for detected objects. Having two YOLO heads implies that the model can process different scales of detection simultaneously, improving its accuracy and robustness in detecting objects of various sizes."

YOLOv8 is characterized by its Fully Convolutional Architecture, which allows for efficient processing of images. As there is no published paper for this model, inference and understanding of the research methodology are achieved mainly by the published code. One of the critical improvements in YOLOv8 over its predecessors is its enhanced backbone network. This backbone is responsible for feature extraction and is more adept at handling small and occluded objects, which is a common challenge in face and eye tracking scenarios. Another improvement worth noting is the elimination of anchor boxes. These have largely been a part of earlier models as they represent the distribution and center-points of bounding boxes. This has resulted in the reduction of the number of predicted boxes, consequently speeding up Non-Maximum Suppression (NMS).\nThe architecture of YOLOv8 is an enhancement of YOLOv5 where the first  convolutional stem is replaced by a . CBS blocks consisting of Convolutional, Batchnorm and SILU are used to replace the main building block and C2f. C2f represents two  convolutions with a residual connection which accepts outputs from the bottleneck and concatenates it. The bottleneck is the same as in YOLOv5 with changes made to the size of the first convolutional layer from  to . YOLOv8 also includes significant changes during training.

A more appropriate and direct comparison would have entailed evaluating the performance of our trained models on the synthetic datasets created by the authors.

The lowest error is observed in YOLOv8, which is close to the results obtained by Ryan et al. YOLOv3 has the highest MSE with 1.33, which indicates significant inaccuracies in its predictions. The average recall metric, which evaluates the model\u2019s ability to detect all relevant instances, indicates a superior capacity to identify relevant objects in YOLOv8. The recall rates for GR-YOLOv3 and YOLOv3 are lower. Despite the absence of the F1-Score data, the prevailing metrics suggest that Ryan et al.\u2019s [36  ###reference_b36###] model surpasses the others in terms of precision, accuracy, and recall. This is quite comprehensive as voxel grids offer a superior representation. This could also be a result of other factors such as the type of augmentations used during synthetic data generation which we did not have information on.\nNonetheless, the frame-based approach we presented demonstrates excellent performance, with YOLOv8 leading in terms of error minimization and localization accuracy. Consequently, we have successfully demonstrated that face and eye tracking can be achieved using a frame-based representation of events.

To begin with, we test the trained models against the largest and publicly available event-based dataset for face tracking, the recent Faces in Event Stream (FES) dataset [9  ###reference_b9###]. This dataset serves as the most comparable benchmark in event-based vision, comprising 1.6 million event streams captured with a Prophesee PPS3MVCD EC, incorporating face bounding box annotations. This data was obtained by sending a formal request to the authors and subsequently, we were given the permission to access and utilise the data for this study. Given that our focus includes eye tracking, we manually annotated the eyes of selected test subjects within FES to facilitate a balanced comparison.\nAdditionally, we evaluate the performance of our models using naturalistic driving data recorded by Ryan et al. [36  ###reference_b36###]. The dataset, which was not publicly accessible, was obtained for our study by requesting its use as a benchmark. Likewise, permission to utilize this data for our research was granted by the authors. The direct comparison with this data enables us to rigorously evaluate our frame-based methodology for face and eye tracking with ECs against the Voxel Grid strategy employed in the cited study.\nIn our final phase of evaluation, we collected sample data using an EVK4 EC, which captured a spectrum of head movements from minimal to extremely rapid. The task of manually annotating bounding box labels for faces and eyes in each frame for the last 2 datasets, though time-consuming, was imperative. This detailed annotation process was critical not only for deriving precise results but also for illustrating the effectiveness of our models across diverse datasets and with varying event cameras.

All the datasets employed in our testing phase were excluded from the training to ensure an unbiased evaluation of the performance of our models.\nThe GR-YOLO model exhibits a robust performance in face detection, particularly when validated with the dataset of Ryan et al. [36  ###reference_b36###]. This was anticipated as the motion simulating approach employed was based upon the operation of a prophesee EC. Therefore, the data obtained from the prophesee EC should yield highly accurate prediction outcomes. The FES dataset shows a decrease in validation results across all metrics. Though it shows good performance in face mAP, this is half what is shown in eye mAP. As the FES dataset is more focused on detecting faces than eyes, some event streams do not highlight the eyes. Therefore, frames from these events were not annotated during manual annotation to avoid assuming the positions of eyes. Thus lower results in face mAP are to be expected, which affects the overall performance of other metrics.\nGenerally across all datasets tested, the efficacy of GR-YOLO in eye detection exhibits a greater variability, accompanied by a significantly lower mAP. This highlights a challenge often encountered when using YOLOv3 for detecting smaller or more detailed objects like eyes. This is more apparent in ECs where the motion is relatively low, and as such, only a few events or no events are generated in eye regions. The overall performance measured by mAP across all datasets is satisfactory, indicating a comprehensive capability to detect faces and eyes from diverse sensors. Precision and recall metrics also support this conclusion. This demonstrates that GR-YOLO not only accurately identifies objects, but also performs consistently across datasets.\nIn contrast, YOLOv8 shows a noticeable improvement in performance across all metrics and datasets compared with GR-YOLOv3. The mAP for faces remains high, with a slight improvement in the FES Dataset and consistent performance in Ryan et al. The eye detection capability significantly improved, as evidenced by the increase in mAP for eyes in the FES Dataset. This enhancement indicates that YOLOv8 better handles the intricacies of eye detection across different sensors. The overall metric evaluation across all objects also sees an increase highlighting the superior general object detection capability of YOLOv8 over GR-YOLOv3 and underscoring the model\u2019s accuracy and consistency in object detection across varied conditions."

As a result, we introduce forward-mode weight perturbation with Hessian information (FoMoH). We then use FoMoH to develop a novel generalization of line search by extending it to a hyperplane search.\nWe illustrate the utility of this extension and how it might be used to overcome some of the recent challenges of optimizing machine learning models without backpropagation.

These parameters are updated by subtracting the tangents that are scaled by their directional derivatives. As a result, their approach only requires forward passes, and avoids the computation and memory costs associated with implementing the backwards pass of reverse-mode AD. While there is still an accuracy gap between forward-mode and reverse-mode optimization approaches [30  ###reference_b30###], there are several recent efforts that have explored alternative ways of leveraging forward-mode AD, with a focus of reducing the variance of the gradient estimator with the increase in dimensions [27  ###reference_b27###, 9  ###reference_b9###].\nThus, the large performance gap between the forward-mode approaches and backpropagation (BP) has been shrinking.\nAn interesting direction to explore, which builds on the existing work in forward-mode AD for optimization, is the introduction of Hessian information.\nSecond-order derivative information provides optimization routines with information about the local curvature. These methods often require access to the Hessian, whose storage is not feasible for high-dimensional problems.\nAs an example, a function, , has a quadratic storage cost of  and a linear compute cost of  reverse-mode gradient evaluations to build the Hessian [23  ###reference_b23###, 6  ###reference_b6###].\nInstead of building the full Hessian through the use of reverse-mode AD, we introduce an approach incorporating Hessian information, known as FoMoH, which significantly outperforms the first-order gradient descent method, FGD. Furthermore, we demonstrate how our approach effectively bridges the gap between a line search and a full Newton step. By incorporating Hessian information, FoMoH leverages second-order derivatives to provide more accurate curvature approximations of the objective function. This allows the method to adaptively adjust the step size and direction with greater precision compared to a simple line search, which only uses gradient information. Simultaneously, FoMoH avoids the computational complexity of a full Newton step, which requires calculation of  where  is the Hessian. As a result, our approach balances the efficiency of a line search with the accuracy of a full Newton method, offering a robust and versatile optimization technique.\nThe central contributions of this paper are as follows:\nWe introduce three new optimization approaches that use forward-mode second-order information.\nWe show how one of these approaches, Forward-Mode Hyperplane Search, generalizes from a line search all the way to Newton\u2019s method, without any need for backpropagation.\nWe demonstrate the performance of the proposed new approaches on optimization problems of different parameter sizes and difficulty to show the advantage of second-order information.\nWe release an AD backend in PyTorch that implements nested forward AD and interfaces with PyTorch models: https://github.com/SRI-CSL/fomoh  ###reference_github.com/SRI-CSL/fomoh###.\nThe rest of the paper is organized as follows. \u00a72  ###reference_### and \u00a73  ###reference_### summarize the related work and relevant preliminary information regarding AD, which is then followed by \u00a74  ###reference_### that outlines what is required to extend forward-mode AD to higher order derivatives. \u00a75  ###reference_### introduces FoMoH and the generalization to our forward-mode hyperplane search. Finally, \u00a76  ###reference_### provides experimental results that explore the behavior of FoMoH. We then conclude in \u00a77  ###reference_###."

+            "text": "There has been considerable interest in developing approaches that avoid reverse-mode AD and its backwards pass. In moving away from backpropagation, it might be possible to build optimization algorithms that more closely align with biological systems [3  ###reference_b3###, 12  ###reference_b12###], or enable neural networks to run on emerging hardware architectures, such as analog optical systems [25  ###reference_b25###]. Baydin et al. [1  ###reference_b1###] introduced FGD as a possible replacement for backpropagation in neural network training by relying on weight perturbations. This removed the truncation error of previous weight perturbation approaches [23  ###reference_b23###] by moving to forward-mode AD. While FGD is a promising backpropagation-free approach,\nthe scaling of FGD to high-dimensional models is challenging due the variance of the gradient estimator.\nThis challenge has led to multiple efforts that have focused on reducing this variance [27  ###reference_b27###, 30  ###reference_b30###, 9  ###reference_b9###]. In particular, a common approach has been to rely on local backpropagation steps to reduce the variance and/or to provide a better guess for the perturbation direction. In our work, we focus on second-order forward-mode optimization approaches, but highlight that these other approaches on variance reduction are orthogonal to our approach and could also be combined together and generalized to FoMoH.\nBecker et al. [2  ###reference_b2###] were one of the first to the use the second-order information to optimize neural networks. This approach leverages a local backpropagation step [14  ###reference_b14###] to capture the diagonal Hessian terms resulting in what they call a \u201cpseudo-Newton step\u201d. Both LeCun et al. [17  ###reference_b17###, \u00a76\u2013\u00a79] and Goodfellow et al. [10  ###reference_b10###, \u00a78.6] provide discussions of the use of Hessian information for neural network training and cover Newton\u2019s method, as well as the Levenberg\u2013Marquardt algorithm [18  ###reference_b18###, 20  ###reference_b20###], conjugate gradients, and BFGS. A key objective of these approaches is to investigate whether second-order information can be leveraged for neural network training without the prohibitively high cost of a full Hessian evaluation. Additionally, the research question then explored is whether the approximated Hessian is still good enough to give the desired advantage over first-order methods. Examples of effective approaches often rely on diagonal preconditioners, with some approximating or directly using the diagonal of the Hessian [34  ###reference_b34###, 14  ###reference_b14###, 2  ###reference_b2###], and others leveraging momentum and a variant of the diagonal of the empirical Fisher [7  ###reference_b7###, 31  ###reference_b31###, 13  ###reference_b13###]. While extending a gradient preconditioner to the full inverse Hessian is generally infeasible, there are approaches that use: block-diagonal approximations, low-rank approximations, and Krylov-subspace based approximations [15  ###reference_b15###, 32  ###reference_b32###]. Additional references for these preconditioners can be found in Martens [21  ###reference_b21###]. Finally, although it is challenging to scale second-order approaches to large neural network models, a recent work, Sophia [19  ###reference_b19###], has managed to show success in using such an approach. Like previous works, they use a diagonal approximation of the Hessian. Importantly, they show that Sophia requires half the number of update steps as Adam [13  ###reference_b13###] to train a language model (GPT-2 [26  ###reference_b26###]). It is worth noting that none of the described second-order optimization methods rely solely on forward-mode AD like the one being proposed in this paper."

For a complete introduction, please refer to Griewank and Walther [11  ###reference_b11###]. We use  to denote a column vector.\nForward-Mode AD [33  ###reference_b33###] applies the chain rule in the forward direction. The forward-mode evaluation, , requires an additional tangent vector, , along with the parameter vector  for a function . The result of the evaluation, , is a function evaluation and the corresponding Jacobian vector product (JVP), where . For a unidimensional output function, the JVP is the directional derivative, . The time and space (memory cost) complexity\nare linear, both approximately twice that of a single function evaluation.111More precisely, the basic time complexity\nof a forward evaluation is constant  times that of the function call [11  ###reference_b11###]. A common implementation of forward-mode AD is to use dual numbers. A dual number  contains a real (primal) component, , and a dual component, . We can think of this as representing a truncated Taylor series, , notationally simplified by the rule . Using this, . A simple example can be shown for the function, . Using dual numbers, , we retrieve the function evaluation and the corresponding well-known product rule: . This can be extended to multiple dimensions, and is the basis of forward-mode AD: lift all real numbers  to dual numbers .\nReverse-Mode AD requires both a forward pass and a reverse pass. The reverse-mode evaluation , also requires the additional adjoint vector, , which is often set to  for scalar-valued functions. Using the same notation as for forward-mode, an evaluation of reverse mode results in the vector-Jacobian product, , as well as the function evaluation. When , this results in the gradient . Reverse-mode is required to store intermediate values on the forward pass that are used during the reverse pass. This results in a higher time and space complexity, that is higher computational cost and memory footprint per call of . However, for the scalar-valued functions () that are common for ML optimization problems, only a single call of  is needed to collect all the gradients compared to  (dimension of inputs) calls of . This is one of the key reasons for the widespread adoption of the reverse-mode AD in current gradient-based machine learning methods, despite the higher memory footprint."

Dual numbers can be extended to truncate at a higher order, or to not truncate at all; and to allow nesting by supporting multiple distinct formal  variables [24  ###reference_b24###]. Specifically focusing on second-order terms is often referred to as hyper-dual numbers (for example in the Aeronautics and Astronautics community [8  ###reference_b8###]). A hyper-dual number is made up from four components, which is written as . In the same manner that we look at imaginary and real parts of complex numbers, we can look at the first derivative parts of a hyper-dual number by inspecting the  and  components, and we can look at the second derivative by inspecting the  component. To understand how this formulation arises, we can introduce the definitions  and replace the Taylor series expansion of a function,  around  with perturbation, , with an evaluation of a hyper-dual number:222Note, we have left our function definition as being a scalar output for pedagogical reasons but nothing precludes a vector or matrix output, which is required for the composition of functions in most ML architectures.\nAn alternative but isomorphic view is to regard  as an element of , with subscripts to distinguish the inner vs outer s; from an implementation perspective, hyperduals can be regarded as inlining the nested structures into a single flat structure."

A typical setting to get exact gradient and Hessian elements is to set  and , where  and  are each a basis of one-hot unit vectors. Therefore, these basis vectors select the corresponding elements of the gradient and Hessian:\nA single loop over the input dimension provides the exact gradient, whereas a nested loop provides the full Hessian. As a side note, a single loop also can give the Hessian vector product. This is done by setting one of the tangent vectors to the chosen vector, and looping through the basis for the other tangent vector.333While interesting, these results might not immediately seem attractive to the ML community. The Hessian calculation of a model with parameters, , would require  function evaluations, whereas Hessian vector products are widely available in many AD libraries leveraging tricks such as a forward over reverse routine [22  ###reference_b22###, 5  ###reference_b5###]. However, the key advantage is that with a single forward pass, we get both first order and second order information in the form of directional derivatives and the local curvature information respectively. We have already seen from Baydin et al. [1  ###reference_b1###] and follow up works [27  ###reference_b27###, 9  ###reference_b9###] that despite the scalar form of the directional derivative, it can still be used to build optimization routines that appear competitive with backpropagation.\nIn this paper, we investigate whether the additional access to local curvature through forward-mode AD can enable improvements over the current FGD algorithm.\nThe Hessian contains the curvature information at a point, , in the form of the second order partial derivatives. When we evaluate a function over hyper-dual numbers we get the bilinear form, . This is a function that operates over two vectors, such that it is linear in each vector separately. The bilinear form\nis common in optimization routines, such as for conjugate gradient descent to assess whether two vectors are conjugate with respect to the Hessian. The value of  tells us about how curvature covaries along the two vectors. In the case where , we arrive at the quadratic form that describes the curvature, which indicates the rate of change of the slope as you move in the direction of . The quadratic form also provides information on the convexity of the function at that point. If , then the function is convex at that point and the Hessian is positive definite. The curvature also indicates the sensitivity of moving in certain directions. For example, when using gradients to optimize a function, taking a gradient step in a region of low curvature is likely to increase the value of the function. However the same sized step in a region of large curvature could significantly change the value of the function (for better or worse).\nThe cost of a single forward pass with hyper-dual numbers is of the same order of time and space complexity\nas the original function call. This reduces the memory cost compared to reverse-mode AD. The forward pass with hyper-dual numbers scales in the same way as the original function call to the number of parameters. However, there is a constant overhead price (no change in computational complexity) to be paid in the form of evaluating the second order terms throughout a forward pass. An example is that the addition of two scalars now requires  additions, and multiplication now requires  products and  additions. However, unlike for reverse-mode, these intermediate values can be overwritten once they have been used to propagate gradient information."

The learning rate for the FoMoH variants is set to  for the Rosenbrock experiments.\nAs an initial illustration of the behavior of each forward-mode approach, we show how a single step looks from a randomly chosen starting point in Figure 1(a)  ###reference_sf1### for FGD, FoMoH, and FoMoH-BP. We plot the expected (average) step across  samples for all approaches in the 2D Rosenbrock function. These steps are shown with solid lines. For each approach, we also plot the sampled steps by superimposing a scatter plot in the corresponding approach\u2019s color. All methods are compared to the Newton step,  shown in red. For FGD, we see that the expected descent direction is the same as the gradient at that point, hence the alignment with FoMoH-BP that directly calculates the gradient. This plot highlights the reliance on a well-chosen learning rate for FGD, whereas FoMoH-BP\u2019s step size is automatically normalized by the local curvature along the gradient. FoMoH (blue), on the overhand, has a descent direction that differs from the gradient and is governed by the distribution of samples that fall on the ellipse defined by the Hessian, . For this point, the Newton step is the descent direction that falls on this ellipse and corresponds to the local minimum of the quadratic approximation. Another insight gained from this figure is that the variance of FGD\u2019s descent direction is less constrained than FoMoH\u2019s descent direction (blue), where the sample direction is controlled by the local Hessian. As a final note, we do not plot FoMoH-2D in Figure 1(a)  ###reference_sf1### as it directly aligns with the Newton step, with very little variance (see \u00a7A  ###reference_###, Figure 5  ###reference_###).\nIn Figure 1(b)  ###reference_sf2###, we now compare the performance of the competing optimization routines for the 2D Rosenbrock function. These results are shown for the same  randomly sampled starting locations for all approaches initialized with different random seeds. We highlight with the thicker line the median performing run. Both axes are on the log scale and show the significant advantage of FoMoH-D, with . We also note the advantage (at least for this 2D example) of all FoMoH approaches that use second-order information. Additionally, the two forward-mode only approaches actually outperform the optimization routines that include backpropagation.\n###figure_1### ###figure_2### We now focus on the performance of FoMoH-D as we increase  from  to the input dimension of the function.

For the Rosenbrock function, we illustrated the behavior of our three new optimization routines: FoMoH, FoMoH-BP, and FoMoH-D, and we compared them to Newton\u2019s method. In particular we were able to show that as one increases the hyperplane dimension of FoMoH-D the method tends to Newton\u2019s method, without the need for any backpropagation. This significant result is shown in Figure 2  ###reference_###. For the learning tasks of logistic regression and CNN classification, we see how the first-order optimization approach of FGD degrades with increasing dimension of the parameter space. We do not see this degradation for FoMoH-D, and we also observe that the second-order information means fewer epochs are needed to reach a better performance. This has the broader impact of improving efficiency, reducing cost, and increasing accuracy in ML optimization routines.\nIn conclusion, we introduced a novel approach that uses second-order forward-mode AD for optimization. We have introduced: forward-mode line search (FoMoH); forward-mode line search with Backpropagation (FoMoH-BP); and forward-mode hyperplane search (FoMoH-D). We have shown how these approaches compare to the previous first-order forward-mode approach of FGD, as well stochastic gradient descent for multiple optimization problems over a wide range of dimensions. Furthermore, FoMoH-D behaves closer to the performance of Newton\u2019s method as  increases. In addition to contributing the new second-order forward-mode optimization routines, we provide a Python package that implements the AD backend and interfaces with PyTorch.\nOur work is a further step in the direction\nof showing the value of cheap second-order information in optimization with the need to scale to even larger dimensions.\nWe expect that future work will be able to mix the advantages gained from first-order approaches with that of second-order approaches."

This paper explores the potential of Large Language Models (LLMs) to streamline or replace the HLS process, leveraging their ability to understand natural language specifications and refactor code. We survey the current research and conduct experiments comparing Verilog designs generated by a standard HLS tool (Vitis HLS) with those produced by LLMs translating C code or natural language specifications. Our evaluation focuses on quantifying the impact on performance, power, and resource utilization, providing an assessment of the efficiency of LLM-based approaches. This study aims to illuminate the role of LLMs in HLS, identifying promising directions for optimized hardware design in applications such as AI acceleration, embedded systems, and high-performance computing.",

High-Level Synthesis (HLS) has emerged as a valuable approach for designing, synthesizing, and optimizing hardware systems. HLS (Coussy et al., 2009  ###reference_b9###) enables designers to define systems at a high abstraction level, independent of low-level circuit specifics, and utilize HLS tools to produce an optimized low-level hardware description of the target system. With current HLS tools (e.g., Vitis HLS, SmartHLS), designers can create application-specific embedded systems using high-level languages like C/C++ and translate them into register-transfer level (RTL) implementations using hardware description languages (e.g., Verilog. VHDL), thereby enhancing design productivity and reducing both design time and cost. Despite the advantages of HLS, the tools can still be time-consuming to use and demand considerable expertise, thus creating the potential for substantial improvement, especially with the integration of technologies like large language models (LLMs).\nRecent advancements in LLMs (Zhao et al., 2023  ###reference_b31###) have showcased their ability to automate various computational tasks, including code generation and software engineering. This presents a unique opportunity to explore the potential of LLMs in streamlining the HLS process, from high-level language specifications to efficient hardware implementations (Chang et al., 2023  ###reference_b7###). The ability of LLMs to understand and generate code, combined with the potential for natural language interaction, can revolutionize the way we design hardware, making the process more accessible and less time-consuming. This integration can lead to significant improvements in design productivity and efficiency, ultimately transforming the landscape of hardware development.\nIn this paper, we explore the burgeoning field of LLMs for HLS, which has sparked growing interest. We first present a taxonomy of LLM use cases for HLS, highlighting the various ways these models can be integrated into the design flow. Building on this foundation, we survey the state-of-the-art, highlighting the most promising research and techniques. To assess the viability of LLMs in the HLS design flow, we perform an experimental evaluation, comparing the Verilog designs generated using a standard HLS tool, specifically Vitis HLS, to those produced with LLM-based approaches. These approaches include direct LLM translation of C benchmarks from the PolyBench Suite (Pouchet and Yuki, 2012  ###reference_b21###) to Verilog using ChatGPT-4o, and the use of LLMs to interpret natural language specifications into both benchmarks and Verilog. Our evaluation focuses on the quality (performance, power, resource utilization) of designs produced by each methodology.\nThis study seeks to answer several key questions: Can existing LLMs generate Verilog code comparable in quality to that produced by traditional HLS tools? What are the advantages and limitations of using LLMs in this context? Could the natural language understanding capabilities of LLMs open up new avenues for hardware design? By addressing these questions, we aim to provide valuable insights into the role of LLMs in HLS and their potential to transform the future of hardware design.\n###figure_1###"

While many current works leverage the popular ChatGPT for their HLS experimentation, both general-purpose and custom-tuned LLMs have been utilized to automate and optimize synthesis processes (Fu et al., 2024  ###reference_b11###). As expected, fine-tuning models on domain-specific data often yields superior performance in generating desired outputs within the HLS workflow. For instance, Nadim et al. (Nadimi and Zheng, 2024  ###reference_b18###) introduced a multi-expert LLM architecture to address the challenges of design complexity. By using specialized models and a complexity classifier, they achieved an improvement of up to 23.9% in the pass@k metric. However, a consistent theme emerging from both existing literature and our experiments is the necessity of human-in-the-loop (HITL) approaches for successful LLM integration in HLS. For example, Collini et al. (Collini et al., 2024  ###reference_b8###) highlighted the significant human expert guidance required for converting a C-based QuickSort kernel to HLS-C. Similarly, Swaroopa et al. (Swaroopa et al., 2024  ###reference_b24###) demonstrated a semi-automated approach for generating HLS-C from natural language using LLMs, acknowledging the need for human intervention in the design process, though their work did not evaluate the quality of the resulting designs. Such a HITL approach leverages the computational strengths of LLMs while retaining the nuanced understanding and decision-making capabilities of human experts, to achieve superior HLS outcomes."

For example, LLMs have shown success in automating the generation of analog/mixed-signal (AMS) circuit netlists from transistor-level schematics (Tao et al., 2024  ###reference_b25###). In the domain of RTL generation, LLMs have demonstrated their capability to generate RTL code from natural language descriptions (Lu et al., 2024  ###reference_b16###) and, as explored in (Blocklove et al., 2023  ###reference_b5###), have the potential to aid in writing and debugging HDL code through conversational interactions with existing LLM tools like ChatGPT. Additionally, LLMs are being integrated into tools like MATLAB and Simulink to translate high-level design specifications into synthesizable Verilog and VHDL code, streamlining the HDL generation process. In the domain of code security, Nair et al. (Nair et al., 2023  ###reference_b19###) investigated the vulnerabilities in hardware code generated by ChatGPT, specifically analyzing common weaknesses enumerations (CWE) and proposing strategies to guide secure hardware code generation.\nBeyond these applications, LLMs are being explored for broader roles in the HLS workflow. Recent work has explored the potential of LLMs to refactor existing C code into HLS-compatible formats, bridging the gap between software and hardware design (Collini et al., 2024  ###reference_b8###; Fu et al., 2023  ###reference_b12###; Swaroopa et al., 2024  ###reference_b24###; Xu et al., 2024  ###reference_b30###). Models like ChatGPT have been leveraged to convert high-level design specifications into synthesizable HDL, targeting specific hardware components such as random number generators (Meech, 2023  ###reference_b17###). They have been used for automated code repair and optimization to improve the quality of HLS-C programs (Xu et al., 2024  ###reference_b30###). Furthermore, LLMs have shown promise in generating HLS pragmas (Fu et al., 2023  ###reference_b12###; Xu et al., 2024  ###reference_b30###), which are compiler directives that can significantly impact the quality of the generated hardware. Moreover, the use of LLMs for automated testbench generation (Qiu et al., 2024  ###reference_b22###; Bhandari et al., 2024  ###reference_b4###) and hardware design verification tasks (Ahmad et al., 2024  ###reference_b2###; Kande et al., 2023  ###reference_b13###) further expands their potential applications in HLS.

Textual descriptions, including high-level design specifications, natural language explanations of functionality, and code snippets in languages like C/C++ often serve as primary input modalities. LLMs can transform these textual inputs into HDL such as Verilog or VHDL, as seen in applications that convert natural language descriptions directly to HDL (Meech, 2023  ###reference_b17###; Blocklove et al., 2023  ###reference_b5###; Lu et al., 2024  ###reference_b16###). Beyond text, advanced LLMs are increasingly capable of handling multimodal inputs, which incorporate images, schematics, or other data types (Chang et al., 2024  ###reference_b6###). This can allow for a more nuanced understanding of design requirements by integrating visual and textual information.\nThe output modalities of LLMs for HLS are equally diverse. Primarily, LLMs can generate synthesizable HDL code from textual or multimodal inputs (Lu et al., 2024  ###reference_b16###). Additionally, LLMs can optimize existing code by automatically inserting and tuning pragmas to enhance the synthesis process. Moreover, LLMs can generate testbenches and verification scripts, which are vital to validate the functionality and performance of the synthesized hardware."

Several key initiatives have emerged to address this need, including the RTLLM benchmark (Lu et al., 2024  ###reference_b16###), which provides a framework for evaluating LLM performance in generating RTL from natural language instructions, encompassing syntax, functionality, and code quality. The RTL-Repo benchmark (Allam and Shalan, 2024  ###reference_b3###) expands this evaluation by assessing LLM capabilities in generating Verilog code autocompletions within large-scale and complex RTL projects, reflecting real-world design scenarios. VerilogEval (Liu et al., 2023  ###reference_b15###) is a framework for evaluating the effectiveness of LLMs in generating Verilog code, including tasks like module implementation, code debugging, and testbench construction, to assess their potential in hardware design automation. Similarly, VHDL-Eval (Vijayaraghavan et al., 2024  ###reference_b28###) is a specialized framework designed to evaluate LLM performance specifically in VHDL code generation. Wan et al. (Wan et al., 2024  ###reference_b29###) explored using LLMs to insert bugs into HLS code, and created a dataset including both correct and injected buggy codes.

We refer to this process as CHLSVerilog.\nHLS tools offer a range of directives to guide the synthesis process, allowing designers to control various aspects of the design, such as loop unrolling, pipelining, array partitioning, and performance optimization. While these directives provide flexibility, the resulting HDL code generated by HLS tools can often be complex and challenging to interpret for designers who are primarily accustomed to higher-level programming languages. This limited visibility into the generated HDL code is a key consideration that motivates the exploration of LLMs in HLS, aiming to improve the design process by providing higher-level abstractions or enhancing code understandability."

This procedure involves the steps to generate Verilog code from high-level specifications and subsequent steps to produce a fully functional accelerator, from simulation to place-and-route. For example, a testbench is necessary to validate the accelerator\u2019s functionality during simulation. A place-and-route-ready hardware accelerator consists of Verilog code, TCL commands to automate the assembly of the accelerator\u2019s design (instantiating IP cores, connecting them, and setting up the overall project structure), and XDC files to specify the constraints of the accelerator such as clock period and I/O delay.\nFigures 3  ###reference_###, 4  ###reference_###, 5  ###reference_###, 6  ###reference_###, and 7  ###reference_### illustrate our CLLMVerilog process for different components of the hardware design flow. The first step defines the context of the generation process, including, but not limited to, the designer\u2019s role, the hardware background, and the constraints that the LLM (ChatGPT-4o, in our case) should follow to better identify the corresponding context and purpose of this process. Figure 3  ###reference_### shows the context we used in our experiments. We identify ourselves as hardware engineers and aim to translate a C program to HDL in Verilog. We specify that this Verilog module should target the Xilinx FPGA part xc7a200tfbg-484-1. Although ChatGPT-4o records the part in its memory, the design is not guaranteed to meet the I/O or resource constraints unless we explicitly instruct the LLM to meet the I/O constraints. If the specification of the part does not exist or is incorrect in the LLM, we must manually provide this information to the LLM.\nAfter providing the role, background, and constraints of the designer and hardware to the LLM, we provide the source code to the LLM. It is important to be mindful of ChatGPT-4o\u2019s limitations: a 128k token limit for combined input and output, with a maximum of 4k tokens for the output alone. If a larger program is needed, it should be divided accordingly. In our experiments, all C benchmarks were within the 128k token limit, allowing us to input the entire program at once. However, due to the 4k output constraint, generating the complete Verilog accelerator required multiple iterations. Once generated, the Verilog output undergoes syntax and design error checking.\nFor designers proficient in hardware design, syntax and design error checking can be performed directly within the LLM. Otherwise, a validation tool like Vivado is necessary. Once an error is identified, we describe the error in natural language to the LLM and regenerate the Verilog code. This process is repeated until successful simulation and implementation in Vivado. We encountered some common errors in the process, such as incorrect data type mapping in I/O (Figure 4  ###reference_###), misrepresentation of sequential and parallel execution (Figure 5  ###reference_###), and state machine implementation errors (figures omitted for brevity). The designer\u2019s expertise level significantly impacts the speed and efficiency of this iterative error resolution process.\nThe final step in the LLM-assisted design flow is generating TCL scripts for IP integration, XDC constraints, and testbench content (Figures 6  ###reference_### and 7  ###reference_###). This step faces similar challenges as previous steps if the LLM lacks knowledge of the latest syntax or specifications, leading to more errors in generated files. For example, defining a proper clock period and calculating IEEE 754 standard floating-point values require the latest specifications. To address this problem, we manually provided the necessary information to the LLM, which learns and adapts over time, potentially reducing errors in future iterations."

These benchmarks encompass computational kernels common in scientific and engineering applications, such as matrix multiplication, 2D convolution, and Cholesky decomposition. We employed ChatGPT-4o as our LLM model, Vitis HLS 2023.2 as our HLS tool, and Vivado 2023.2 for implementation targeting a Xilinx xc7a200tfbg484-1 FPGA. For each benchmark, we generated designs using all four approaches and collected data on resource utilization, power consumption, execution cycles, and critical path delay from Vitis HLS and Vivado. Note that the NLLLMVerilog approach yielded an initial Verilog design with an equivalent structure to the initial Verilog design generated using the CLLMVerilog approach. As such, these approaches share the same steps after the initial input stage, and thus have the same evaluation data. We tracked the number of prompts used to generate HLS-C, Verilog, TCL, XDC, and testbench content for the LLM-based approaches. For a fair comparison, we disabled automatic optimizations like pipelining in Vitis HLS. For LLM-based approaches, we used LLMs to generate all necessary content (Verilog code, TCL scripts, IPs, testbenches, XDC files) to form a complete project.\n###table_1### ###table_2###"

As demonstrated in Sec. 5  ###reference_###, the CLLMVerilog and NLLLMVerilog approaches share the same prompts after the initial input, leading to identical place-and-route results. For the NLLLMHLS-C approach, we also include the number of prompts needed to generate the HLS-C code. Since we targeted the same functionality as the C benchmark, the NLLLMHLS-C and CHLSVerilog approaches share the same place-and-route outcomes.\nNotably, generating the Verilog code generally required the most prompts compared to other file types. But the number of prompts required varied significantly depending on the benchmark, as well as our growing familiarity with the LLM\u2019s behavior with Verilog generation. The syrk benchmark, for example, required considerably more interaction with the LLM compared to atax (the last benchmark we worked on). The syrk kernel exhibits a higher level of complexity, containing four nested loops with multiple multiplications in a single operation and three 2D arrays for inputs and outputs. Conversely, atax only comprises two nested loops and one 2D array for input. This suggests that the inherent complexity of the benchmark code, as well as our initial learning curve to effectively prompt the LLM to minimize errors, heavily influenced the number of prompts needed for accurate Verilog generation. As we gained experience and refined our prompting strategies, we were able to consolidate prompts, leading to faster generation for subsequent benchmarks. In contrast, the number of prompts for TCL generation remained relatively consistent across all benchmarks, implying that this task is less sensitive to the specific characteristics of the input code. The complexity of the benchmark and the designer\u2019s growing familiarity with LLM interaction are key factors in determining the number of prompts needed for successful Verilog generation, although prior design experience can also play a role.\nTable 2  ###reference_### presents the simulation and implementation results for both LLM-based and HLS-based approaches. For each benchmark, LLM refers to the CLLMVerilog and NLLLMVerilog approaches, while HLS refers to NLLLMHLS-C and CHLSVerilog approaches. To determine the quality of a resulting hardware accelerators, the evaluation metrics include execution cycles, resource utilization (FFs, LUTs, Slices, DSPs, and BRAMs), total power consumption, and critical path delay.\nA key observation is the significant variation in results across different benchmarks. For the syrk and mvt benchmarks, the LLM-based approaches consume more resources (except DSPs and BRAMs) compared to HLS. This is attributed to the use of LUT RAM for the inner matrix in the LLM-generated designs.\nHowever, for the remaining seven benchmarks, LLM-based approaches consistently outperformed the HLS-based approaches across all metrics. This includes a notable reduction in resource utilization (with an average decrease of 38.67%), a significant improvement in execution cycles (average reduction of 64%), and a substantial reduction in total power consumption (average reduction of 38.67%). For the critical path, the HLS-based approach outperformed LLM-based approaches by an average of 28.82%.\nOverall, the results in Table 2  ###reference_### demonstrate the potential of LLMs in optimizing various aspects of hardware design. While the LLM-based approaches did not outperform in every metric for all benchmarks, their consistent success in the majority of cases, particularly in resource utilization, power consumption, and often execution cycles, highlights the promise of this technology for HLS. Further research is needed to refine and expand these capabilities, and explore them in a wider variety of usage scenarios, but the current results are encouraging and suggest that LLMs could play a significant role in the future of hardware design automation."

The majority of studies have focused on the potential of LLMs to streamline the design process, enhance automation, and improve the quality of generated hardware. However, they have largely overlooked the energy consumption associated with both the training and inference of these models.\nLLMs, particularly large-scale models like GPT-3 and GPT-4, are notorious for their computational demands. Training LLMs can consume hundreds of megawatt-hours to several gigawatt-hours of electricity (Schwartz et al., 2020  ###reference_b23###). Even inference, the process of generating responses to prompts, can be computationally intensive, requiring substantial energy resources. The Electrical Power Research Institute (EPRI) estimates that a single ChatGPT query can consume approximately 2.9 W-hours of energy\u2014nearly 10 times the power of a single Google search (Electric Power Research Institute, 2024  ###reference_b10###)\u2014a considerable amount when numerous queries are needed for HLS tasks. This raises concerns about the overall energy efficiency of incorporating LLMs into the HLS flow. Given that a primary goal of HLS is to design hardware accelerators that are more energy efficient than general-purpose computers, the energy overhead of utilizing LLMs could outweigh the intended benefits.\nFurthermore, the process of fine-tuning LLMs for specific HLS tasks can exacerbate the issue of energy consumption. Fine-tuning involves retraining the model on domain-specific data, which is computationally expensive. If the energy cost of fine-tuning and utilizing an LLM is greater than the energy saved across all resulting hardware designs, then employing LLMs in this way would be counterproductive for energy efficiency.\nThe lack of attention to power/energy implications in current research raises concerns about the sustainability and practicality of LLM-driven HLS. As the field progresses, it is imperative to thoroughly investigate and quantify the energy costs associated with LLM utilization. This will enable a more comprehensive evaluation of the trade-offs between design efficiency and power consumption, ultimately leading to more informed decisions regarding the appropriate use of LLMs in HLS."

+    "abstract": "Document retrieval systems have experienced a revitalized interest with the advent of retrieval-augmented generation (RAG). RAG architecture offers a lower hallucination rate than LLM-only applications. However, the accuracy of the retrieval mechanism is known to be a bottleneck in the efficiency of these applications. A particular case of subpar retrieval performance is observed in situations where multiple documents from several different but related topics are in the corpus. We have devised a new vectorization method that takes into account the topic information of the document. The paper introduces this new method for text vectorization and evaluates it in the context of RAG. Furthermore, we discuss the challenge of evaluating RAG systems, which pertains to the case at hand.",

It has seen a sudden rise in popularity due to the availability of improved large language models (LLMs), especially since the release of LLaMA models [2  ###reference_b2###].\nRAG system works as follows: (1) Text corpus is split into chunks and each chunk is vectorized. (2) User query is vectorized. (3) A similarity search is performed to find the chunk closest to the vectorized query. (4) The retrieved chunk is fed to the LLM along with the user query. (5) LLM uses this input to generate a free-form response.\nOne of the main bottlenecks in the performance of RAG systems is the retrieval step. The accuracy of the similarity search depends on multiple factors, including the choice of the similarity search algorithm, embedding method, and size of the indexed corpus. Corpus size becomes especially problematic if we are dealing with very similar documents."

Our proposal is to use the available topic information of each chunk (i.e. document) and add it to the retrieval process. We have successfully implemented two such methods in industrial settings, and this paper attempts to generalize and evaluate these methods. The first method relies on creating a new document embedding by combining the original document embedding with the topic embeddings generated from the entire topic. The second method consists of two steps (1) find the topic, and (2) find the document within the topic.\nOur contributions in this paper are as follows:\nPropose two new methods for using topic metadata during the document retrieval process.\nEvaluate the suggested methods with calculating the distance measures on embedded documents.\nPropose a detailed problem statement for the next stages of this work.\nThe paper is structured as follows: The next section contains a review of relevant literature on these topics. The third section provides a detailed explanation of the proposed methods. The fourth section consists of two parts. First part outlines our experiments, their explanations, and results. A comprehensive discussion of our results, the main shortcomings of our work, as well as suggestions for future research take place in the second part. We conclude with the paper in the fifth section."

[3  ###reference_b3###] uses this idea to create a code summarization tool. Multimodal RAG systems are also seeing increasing popularity. [4  ###reference_b4###] implements a competitive image and caption generation system with RAG architecture.\nVectorization is an integral part of RAG systems. Traditional vectorization techniques include bag-of-words [5  ###reference_b5###], which simply uses word frequency and term frequency-inverse document frequency [6  ###reference_b6###], which additionally takes into account how unique the word is to a particular document.\nRelatively modern approaches include Word2Vec, GloVe, and fastText. Word2Vec [7  ###reference_b7###] can use either continuous bag-of-words or continuous skipgram models. GloVe [8  ###reference_b8###] is a log-bilinear regression model that was trained on a word-word cooccurrence matrix. fastText [9  ###reference_b9###] is a skip-gram model that treats words as a combination of character n-grams.\nThe latest family of text vectorization methods relies on transformer-based language models. BERT [10  ###reference_b10###] is a textbook example of this. These models usually use a masked attention mechanism to learn the context of tokens in a text. This information can later be used in various tasks, such as named entity recognition and sentiment analysis. The main advantage of this approach is that embeddings are contextual, i.e. they change depending on their place in the text. This is not the case with the aforementioned methods.\n[11  ###reference_b11###] exploits inherent hierarchical structure in the data during the embedding process. Our work is similar but distinct: We use explicit hierarchy, not implicit. As far as we know, no work has attempted this. [12  ###reference_b12###] attempts a similar approach to enhance the performance of image classification models on ImageNet.\nAll of the mentioned works are either language-agnostic, or English-specific. Our dataset is in Azerbaijani, therefore works for the Azerbaijani language are of special interest to us.\nAmong the open-source embedding models, some claim to have an understanding of the Azerbaijani language. Google has released a multilingual version of the famous BERT model. We are aware of several unpublished attempts to use this model (directly or by fine-tuning) for various NLP tasks in Azerbaijani, all of them with limited success. Due to this, we avoided using the model as an embedder. Another multilingual model that has some understanding of Azerbaijani is mGPT. This is an unofficial version of the GPT-2 model released by [13  ###reference_b13###] that was trained in a text corpus consisting of multiple languages. Its text generation capabilities in Azerbaijani are not satisfactory. This is why we did not use it in the generation part of our RAG systems."

We simply chunk the document and embed these chunks separately.\nStep 2: Separate documents into topics.\nWe assume the topic information is provided either implicitly or explicitly. In any case, we need to have explicit topic labels by the end of this stage.\nStep 3: Creating topic embeddings.\nTopic embeddings are supposed to be a vector of the same size as document embeddings. If we are using a neural network like BERT to embed the text, we usually cannot feed the entire topic into the model. We can bypass this by taking an element-wise average of all document embeddings for that topic. If we are using a statistical method like TF-IDF, we can run it on the entire text regardless of the text length. However, we expect both the original document embeddings and the topic embeddings to use the same embedding method. Figure 1  ###reference_### visualizes the process of obtaining topic embeddings from documents.\nStep 4: Update the document embeddings\nWe propose two alternate versions here:\nAverage method: Take an average of document embeddings and topic embeddings.\nAppend method: Concatenate document embeddings and topic embeddings.\nThe second method creates a new problem because now the embedding dimension of a query does not match the dimensions of our embedded documents. To solve this problem, we can duplicate the length of our query embeddings."

You can find these laws in Table I  ###reference_###. OpenAI\u2019s \u201dtext-embedding-3-small\u201d embedding model has been used to embed the chunks. Each law is treated as a distinct topic. We then used both the average method and the append method to update the document embeddings.\nBy treating topics (i.e., laws) as cluster labels, we have evaluated the \u201dclustering results\u201d of three methods:\noriginal embeddings\naveraged embeddings\nappended embeddings\nTo visualize the embeddings of different methods, the tSNE algorithm has been used to reduce the number of dimensions to 2 [14  ###reference_b14###]. You can see the results in Figure 2a  ###reference_sf1### and 2b  ###reference_sf2###.\nTo accurately evaluate our proposed methods, it is essential to use a dedicated RAG evaluation dataset. Although we initially attempted to construct this dataset synthetically, we recognized the limitations of this approach and concluded that a natural evaluation dataset is necessary. We have explored this issue in detail in the section B.\nAnother approach to calculate the performance of these \u201dclustering models\u201d is using the cluster validity indices. These indices provide insights into how well the embeddings separate different topics, which is crucial for ensuring that similar documents are grouped effectively\u2014a key factor in improving retrieval performance.\nWe have used three different indices:\nSilhouette Coefficient\nDavies\u2013Bouldin index\nCalinski\u2013Harabasz index\nThe Silhouette Coefficient, ranging from -1 to +1, measures clustering effectiveness, with higher values indicating better clustering. In contrast, the Davies-Bouldin Index (DBI) assesses cluster separation and compactness, where lower values signify better quality. The Calinski-Harabasz (CH) Index evaluates how well-separated and dense clusters are, with higher values indicating better clusters, typically identified by a peak in the index. Together, these metrics provide a comprehensive assessment of clustering performance.\nThe results are available in Table II  ###reference_###. As you can see, adding topic embeddings to the original embeddings results in better separation of different topics. The average method performs better than the append method, although we suspect that it may be data-specific. As future work, these experiments can be performed on larger and more variable datasets to assess the methods\u2019 performance against each other.\nWe were unable to evaluate the \u2019Two-stage document retrieval\u2019 method due to limitations in the evaluation dataset, which will be discussed further.\n###figure_2### ###figure_3### ###figure_4###"

This dataset needs to have the following features:\nA text corpus with topic labels\nNatural queries that can be answered based on a part of this corpus.\nUsing this dataset, one can first embed the queries with traditional and our proposed methods, then run the similarity search on each of them to match the queries with respective documents, and hence get an evaluation score to make a fair comparison between traditional RAG system and our approach.\nThis first feature is easy to attain. We have already performed some analysis on such datasets. We have attempted to gain the second feature by synthetic query generation, but it did not achieve any better result than normal RAG system, because generated queries are highly specific to the chunk provided. For example, we used the following query:\n\u201dGiven the following context, generate a question that would be asked by a curious citizen:\nContext:\nArticle 25. Right to equality\nI. Everyone shall be equal before the law and the courts.\nII. Men and women possess equal rights and freedoms.\nIII. The State shall guarantee the equality of rights and freedoms to everyone, irrespective of race, ethnicity, religion, language, sex, origin, property status, occupation, beliefs or affiliation with political parties, trade union organisations or other public associations. Restrictions of rights and freedoms on the grounds of race, ethnicity, religion, language, sex, origin, beliefs, or political or social affiliation are prohibited.\nIV. No one may be harmed, granted advantages or privileges, or refused to be granted advantages and privileges on the grounds laid down in Paragraph III of the present Article.\nV. Everyone shall be guaranteed equal rights in any proceeding before state authorities and bearers of public authority that decide upon his/her rights and duties.\nVI. Persons with impaired health are entitled to all rights and carry all duties enshrined in this Constitution, except in cases when enjoyment of rights and performance of duties is impeded by their limited abilities.\u201d\nThis resulted in the following response:\n\u201dWhat measures are in place to ensure enforcement of Article 25, particularly regarding equality before the law and in courts, as well as the guarantee of equal rights and freedoms regardless of various personal characteristics?\u201d\nAs you can see, if we generate a large dataset automatically using these prompts, we will end up with questions that exactly match the provided context (i.e., chunk). Because the content of the queries are highly related with the document chunks, our proposed methods achieve similar performance as the traditional RAG system.\nAlthough the synthetic query generation attempts did not work, we have tried it on the English version of our dataset. As far as we are concerned, no LLM can generate natural text in Azerbaijani at a level that would be sufficient for this task. Due to these restrictions, we are researching the possibility of creating a natural dataset. We can use logs of one of our chatbots in production for this, or we can create an annotator team to build the dataset.\nAnother inherent limitation of our approach is that it depends on the existence of topic metadata. It would be interesting to devise a method to infer the topic information from the raw data itself, although we do not believe that there is a generalizable approach to this problem."

Because FL has access to the on-device data which is not available on centralized server-side training, it\u2019s specially good at learning on-device related patterns, e.g. whether users have feedback to the on-device apps. Moreover, FL can also be combined with centralized server training under a joint training framework [3  ###reference_b3###] to mitigate distribution shift of FL and further improve the model quality.\nWith the above advantages, one of the drawbacks of FL is that the models have to be trained on users\u2019 devices where only limited resources such as memory and computation power are available. The problem becomes worse given that recent models are getting larger and larger such as large language models (LLM) ChatGPT [4  ###reference_b4###] and PaLM [5  ###reference_b5###]. For end-to-end automatic speech recognition (ASR) models [6  ###reference_b6###, 7  ###reference_b7###], the performance is also subject to the model size. Specifically, the Conformer-based ASR model [8  ###reference_b8###, 7  ###reference_b7###, 9  ###reference_b9###] usually requires 120150 million parameters to achieve the desired recognition quality. Models of this size requires several GB of training memory, e.g. [10  ###reference_b10###], hence it is a big challenge for FL.\nEfficient FL methods have been proposed to relieve the resource burden on FL devices. There are generally two categories of the related works. First, from the model perspective new training algorithms are proposed, including pruning technique [11  ###reference_b11###] and dropout method [12  ###reference_b12###] to reduce the model size, gradient checkpointing [13  ###reference_b13###] to recompute the gradients in backward propagation and quantization method [14  ###reference_b14###, 15  ###reference_b15###] to reduce the variables precision. Second, FL related algorithms are designed, including federated dropout[16  ###reference_b16###] to train smaller models on clients, federated pruning[17  ###reference_b17###] to reduce the overall model size, online model compression (OMC) [18  ###reference_b18###] to quantize the model to lower precision and partial variables training [19  ###reference_b19###] to only compute partial gradients to save the memory usage.\nHowever, the above works only focus on one aspect of the system and it\u2019s unknown if the integration of different approach would enable the FL of ASR models.\n###figure_1### In this paper we study the FL of Conformer based ASR model with 130M parameters, which is the largest model for FL so far. Our work potentially paves the road to train other large models like LLMs in the future. We first build different methods into one system and show how the consolidated system works together. Then we study the problem of how to improve the model quality with FL. Because FL is good at learning the on-device usage patterns, we design the FL algorithm as follows. For each user, there is an incumbent ASR on the device to generate the transcript from user audio. We observed that users might edit the original transcripts to correct the errors. For example, if a user said \u201ccovid\u201d and the incumbent ASR outputs \u201ccovert\u201d, then users may change the output to \u201ccovid\u201d again. Therefore, we utilize user-correction actions on devices to improve the model performance on the \u201dcorrected\u201d words. Figure 1  ###reference_### highlights our approach. At the beginning of a FL round, the server selects the clients that have the correction actions. Then the server sends a \u201cprocessed\u201d (e.g. quantized/pruning/reduced) model to clients. Clients runs a data filtering method to only use the \u201ccorrection\u201d data as training examples, and partially train the model under the resource constraint. Then we design a weighted client aggregation (WCA) algorithm to update the trained model on server. Our contributions are summarized as follows.\nTo our knowledge, this is the first real-world FL application that successfully trains the production-grade ASR model of 130M parameters. We explain the FL system in Section 2  ###reference_###.\nThis is also the first paper that shows the ASR quality can be improved by FL. We propose the WCA algorithm to refine the data and label quality of clients based on the user-corrections, described in Section 3  ###reference_###.\nWe conducted real-world FL experiments to demonstrate the performance of our system in Section 4  ###reference_###. We report that the training efficiency is greatly increased, which is measured by (1) the memory usage and (2) transportation size between server and clients, and the WER of FL models is effectively boosted."

+            "text": "In this section we describe how the FL system is built to train the ASR models. The bottleneck of the FL system consists of two constraints: (1) the on-device peak memory usage and (2) the transportation size between server and clients. The two constraints are also positively correlated as they can be optimized together.\nFirst we combine the existing algorithms together in our system as a baseline, meaning that all the following methods are applied by default unless explained further. We enable the gradient checkpointing method [13  ###reference_b13###] in the Conformer model to reduce the memory usage. Moreover, we use the FedSGD [1  ###reference_b1###] algorithm to only take one batch of data as we observed that more examples lead to more memory usage with on-device CPU training [10  ###reference_b10###]. To further reduce the memory consumption, we set a small batch size like 2. With this setting, it means the convergence speed might be slower compared to large batch size and FedAVG [1  ###reference_b1###]. But it can be compensated by more FL rounds and large report goal (the number of clients participating in one FL round). Between server and clients, transportation compression methods [20  ###reference_b20###] are applied to reduce the network load. Next we add two methods on the baseline system including OMC and partial model training.\nOMC. We build the OMC [18  ###reference_b18###] method in our system to reduce both the model size and the memory usage.\nSpecifically, the OMC method is the step  in Figure 1  ###reference_###. Before sending the model to clients, the server quantizes the variables to low-bit precision [21  ###reference_b21###]. To balance the quality degradation and the training efficiency, we quantize the matrices variables to float16 and keep other variables in the original float32 format as the model quality is more sensitive to the biases and activations. Then the server sends the quantized models to clients and clients compute gradients with the same precision of the variables. In this way, both the download and upload sizes are reduced with the float16 format. The memory usage is also reduced because variable storage memory of float16 variables is smaller compared to float32 while the gradient computation is bounded by gradient checkpointing [13  ###reference_b13###]. The results are reported in our experiments.\nPartial model training. We build an updated partial model training [19  ###reference_b19###] corresponding to the step 4 in Figure 1  ###reference_### to reduce the memory usage and the upload size. It sets a subset of trainable variables and non-trainable variables in the model. In this way only a subset of gradients, i.e. for the trainable variables, needs to be computed and uploaded. And the non-trainable variables stay frozen during the training. Moreover, we freeze consecutive bottom encoder layers and only set the decoder and top encoder layers as trainable. When combining it with OMC, we observed that partial model training converges slower. To boost the convergence speed, we de-quantize the trainable variables to float32 again. To summarize, float32 variables consist of (1) all trainable variables from the decoder and top encoder layers and (2) the activations in non-trainable variables from the bottom encoder layers. And float16 includes matrices in non-trainable variables from the bottom encoder layers.\nThe performance is then shown in our experiments."

+            "text": "We explain our algorithm to boost the model quality of FL. The high level idea is to utilize the user-correction actions to refine the quality of data and labels with weighted client aggregation in FL.\nClient selection. To adopt the user-correction data, FL server selects the clients containing the corrections at the step 1 in Figure 1  ###reference_###. At the beginning of an FL round, the server sends all clients an eligibility test designed to check if a client has the user-correction data. If a client passes the eligibility test, it will continue to participate the FL round. Otherwise, the client will drop out from the FL round. The server will keep sending the eligibility test until enough clients are collected to reach the expected report goal. In this way, all participating clients will have the correction data.\nData filtering on devices. At the step 3 in Figure 1  ###reference_### when a client receives the model, the client needs to filter the data first. The purpose of the data filtering is to only take the user-correction data in the FL training. If the client batch size larger than 1, to make sure a client has enough data to form a batch of data after the filtering, we design the eligibility test to check if a client has enough ( the batch size) user-corrections. Another way is to duplicate the existing data to form a batch, which will change the training data distribution considered in the following WCA algorithm.\nAnother benefit of client selection and data filtering is to eliminate the \u201cincorrect\u201d corrections, e.g. a user said \u201ccovid\u201d but got \u201ccovert\u201d as transcript, then the user changed the transcript to \u201ccovertcovid\u201d incorrectly. Because the true data is inaccessible in FL, such \u201cincorrect\u201d corrections also participate in the FL training and pollute the training data. Therefore, we need to filter out such \u201cincorrected\u201d examples. To do so, we use heuristics to estimate and quantify the quality of a correction in the eligibility test, e.g. the word length difference before and after a user edit should be smaller than a threshold. If the quality of correction is low by the hueristic, we eliminate the example.\nWeighted Clients Aggregation. At the step 5 in Figure 1  ###reference_###, the server aggregates all the client uploads, i.e. the gradients from FedSGD computation, together to update the server model. At this time, we propose a WCA algorithm to compute the server model update. The motivation of WCA is to align the distribution of training data to the target distribution to boost the training quality. In particular, our target distribution is based on the list of corrected words denoted by , i.e. a special distribution containing the incumbent model errors.\nThere are usually two aggregation methods in FL: (1) the simple averaging as  where  is the model deltas of  clients; and (2) the example based aggregation as  where  is the number of participating examples of the each client in FedAVG. However, these aggregation methods have not considered the quality of the clients data. Thus the model quality may be degraded due to unexpected data as discussed before. To fix this problem, we propose a WCA algorithm as  where  is the designed weights of  clients as Algorithm 1  ###reference_###.\nThe key of WCA is how to design the weights .\nBecause user-correction pattern may be different from the training data, we need to make the best of the corrections.\nFor example, if the correction from \u201cpie torch\u201d to \u201cpytorch\u201d is rare, we need to assign higher weight to it. Otherwise the gradient contribution of the example will be submerged in the aggregated gradients and vanish in the learned model.\nTo this end, we propose two methods (1) frequency based weights and (2) frequency and accuracy based weights. Given the set of corrected words , the frequency based weights compute the frequency of each word in  among all clients. Such frequency can be derived by computing the differentially private histogram [22  ###reference_b22###] of words on the client pool, i.e.  is the differentially private frequency of word . Then for each word  in the example  containing the corrected transcript of client  at line 7  ###reference_7### in Algorithm 1  ###reference_###, the  can be computed as follows.\nIn this way, we have higher weights for rare words and less weights for frequent words in . Based on this, the frequency and accuracy based weights also incorporate the word accuracy of the incumbent ASR model that generates the transcripts in the first place. The accuracy  denotes how well the incumbent model recognizes a word . The higher accuracy mean the word is recognized well and lower accuracy means the word is recognized poorly. Then the  can be computed as Equation 2  ###reference_###."

All experiments were conducted on the real-world FL with users\u2019 smartphones including Google Pixel phones.\nModel Architecture. Because our objective is to train the large ASR models, we chose the production-grade Conformer [7  ###reference_b7###, 9  ###reference_b9###] model that has about 130M parameters. The model consists of a causal encoder for streaming case and another non-causal encoder for non-streaming case. We only train the causal encoder and the decoder for the streaming cases, although our method can be easily extended to the non-causal encoders.\nMetrics. To evaluate the FL training efficiency, we measure the metrics of transportation size between server and client, and the averaged clients peak memory usage. For the model quality, we use two WERs: (1) the \u201cgeneral WER\u201d refers to the WER on all evaluation datasets; and (2) \u201ctarget WER\u201d refers to the WER on the utterances containing only the corrected data in . Because the objective is to improve the quality on the correction dataset, we mainly focus on the \u201ctarget WER\u201d while maintaining the general WER at the same level. The baseline WERs from the pre-trained model is \u201cgeneral WER\u201d 4.4 and \u201ctarget WER\u201d 17.5."

To evaluate the benefit of OMC method, we performed experiments on a 6-layer encoder Conformer model (under a 250MB download size constraint) to compare the metrics with and without OMC. Table 1  ###reference_### shows the result. The OMC method reduces the download and upload size by 40MB and 25MB. The peak memory usage is also reduced by about 150MB. Note that the transportation compression methods [20  ###reference_b20###] are applied by default, and hence the transportation size is smaller than parameter memory size.\nPartial model training. Next we report the evaluation of partial model training in Table 2  ###reference_###. The upload size is reduced because only the gradients of trainable variables are uploaded. The peak memory usage is also reduced because the non-trainable layers are frozen without gradient computation. Because float16-OMC method is applied by default, partial model training actually increases the download size because the trainable parameters are extended to float32 precision."

OMC and partial model training were also conducted with no significant findings, i.e. float16-OMC is close to the float32 precision; and more trainable variables improve the model quality. Hence we skip the report of ablation studies.\nWER improvement. The results are summarized in Table 3  ###reference_### where each row adds a new method to the above row. The initial FL had general WER 4.4 and target WER 17.2. When the client selection method was added, the quality is not improved because clients might use unrelated examples. Thus we add the data filtering method to specify the training examples, and achieved general WER 4.4 and target WER 16.9. Next we added the two WCA methods, and the frequency and accuracy based WCA obtained the best result of general WER 4.4 and target WER 14.9.\n###figure_2### ###figure_3### WER trade-off. Because our objective is to improve the target WER, we need to consider the WER trade-off between the general WER and target WER. Figure 2  ###reference_### shows the convergence curves of the two WCA methods. We can see that in Figure 2(a)  ###reference_sf1### the general WER started to deteriorate after a FL round while the target WER keeps getting better in Figure 2(b)  ###reference_sf2###. To balance the two WERs, we keep the general WER under the same level of 4.4 and take the corresponding target WER. Advanced trade-off can be designed in future works to further improve the performance."

+    "abstract": "In this work, we introduce LightCNN, a minimalist Convolutional Neural Network (CNN) architecture designed for Parkinson\u2019s disease (PD) classification using EEG data. LightCNN\u2019s strength lies in its simplicity, utilizing just a single convolutional layer. Embracing Leonardo da Vinci\u2019s principle that \"simplicity is the ultimate sophistication,\" LightCNN demonstrates that complexity is not required to achieve outstanding results. We benchmarked LightCNN against several state-of-the-art deep learning models known for their effectiveness in EEG-based PD classification. Remarkably, LightCNN outperformed all these complex architectures, with a 2.3% improvement in recall, a 4.6% increase in precision, a 0.1% edge in AUC, a 4% boost in F1-score, and a 3.3% higher accuracy compared to the closest competitor. Furthermore, LightCNN identifies known pathological brain rhythms associated with PD and effectively captures clinically relevant neurophysiological changes in EEG. Its simplicity and interpretability make it ideal for deployment in resource-constrained environments, such as mobile or embedded systems for EEG analysis. In conclusion, LightCNN represents a significant step forward in efficient EEG-based PD classification, demonstrating that a well-designed, lightweight model can achieve superior performance over more complex architectures. This work underscores the potential for minimalist models to meet the needs of modern healthcare applications, particularly where resources are limited.",

+            "text": "Parkinson\u2019s disease (PD) is a common yet debilitating neurodegenerative disorder affecting 2% of people over the age of 65 years[14  ###reference_b14###]. It is a progressive disorder that demands early and accurate diagnosis before a major loss of the dopaminergic neurons to improve patient outcomes[13  ###reference_b13###]. The diagnosis of PD is clinical and can be difficult without significant physical signs or symptoms. Electroencephalography (EEG) is a promising tool for non-invasive monitoring of subtle neurophysiological changes, offering potential for PD diagnosis. Recent studies have associated PD with various changes in EEG signals[18  ###reference_b18###, 4  ###reference_b4###]. However, the complexity of EEG data presents significant challenges that require advanced machine learning models for detecting PD. Most existing deep-learning methods for PD classification using EEG data are complex and computationally expensive, which can hinder their practical application, especially in resource-constrained environments.\nIn this work, we propose LightCNN, a lightweight Convolutional Neural Network (CNN) architecture designed for efficient and effective classification of PD using EEG data. LightCNN stands out for its simplicity, utilizing just a single convolutional layer to achieve high performance. The motivation behind LightCNN is rooted in the principle that simplicity can be powerful. By focusing on essential features and reducing computational overhead, LightCNN not only offers high accuracy but also ensures interpretability and ease of deployment, especially in environments with limited resources, such as mobile and embedded systems.\nTo benchmark the performance of LightCNN, we compare it against several established deep learning architectures using EEG data from 46 participants, comprising 22 individuals with PD and 24 healthy controls. The results demonstrate that LightCNN not only rivals but exceeds the performance of more complex architectures, offering a powerful and computationally efficient alternative for PD classification. This makes LightCNN a promising candidate for real-time applications and resource-constrained environments, where both accuracy and efficiency are critical. Furthermore, we analyze the features captured by LightCNN and demonstrate its ability to identify neurophysiological patterns in EEG signals that are clinically relevant to PD. This capability, combined with its computational efficiency, positions LightCNN as a valuable tool for both research and clinical applications in neurodegenerative disease detection such as PD.\nThe rest of the paper is organized as follows. Section 2  ###reference_### discusses prior deep learning approaches for EEG-based classification of PD in the literature. Section 3  ###reference_### provides a detailed architecture and methodology of our proposed method, LightCNN. Section 4  ###reference_### details our experiments and the outcomes of our results are given in Section 5  ###reference_###. The ablation study is provided in Section 6  ###reference_###. Finally, Section 7  ###reference_### is the discussion, and Section 8  ###reference_### concludes the paper."

In this study, we focused on PD classification using EEG data from the resting state. In this category, Oh et al. [12  ###reference_b12###] proposed a 13-layer CNN that achieved an accuracy of 88.3%, a sensitivity of 84.7%, and a specificity of 92% using EEG data from 20 PD and 20 control subjects. Lee et al. proposed a hybrid model [8  ###reference_b8###] consisting of a CNN and long-short-term memory (LSTM) layer achieving accuracy of 96.9%, precision of 100%, and recall of 93.4% from 20 PD and 21 healthy subjects. Later, they proposed a modified version [9  ###reference_b9###] with CNN and gated recurrent unit (GRU) layers achieving 99.2% accuracy, 98.9% precision, and 99.4% recall.\nAdditionally, several vision-based architectures have been proposed for EEG-based PD classification tasks. For example, Loh et al. [11  ###reference_b11###] proposed GaborNet which consists of 2D-CNN layers and works on Gabor-transformed spectrogram images of EEG data (15 PD and 16 Controls) achieving an accuracy of 99.46% for 3-class classification (healthy vs PD with and without medication). Shaban et al.[15  ###reference_b15###] proposed a 20-layer 2D-CNN model applied on Wavelet-transformed images of EEG and achieved 99.6% in the 3-class classification problem mentioned above. Khare et al. [5  ###reference_b5###] proposed PDCNNNet which has 4 layers 2D-CNN applied on image-transformed EEG data achieving 99.97% accuracy.\nApart from these, several deep learning architectures are proposed for various EEG-based classification tasks such as EEGNet [7  ###reference_b7###] and ConvNets [19  ###reference_b19###]."

Out of these, elevated beta rhythms among PD participants are well-established which correlates with the PD-related movement symptoms [10  ###reference_b10###]. Consequently, group-wise PSD of PD and healthy control participants in our training dataset showed an elevated beta peak in PD participants as well as elevated delta rhythm in healthy controls (Figure 2  ###reference_###). Interestingly, there was a sharp artifact peak at 60 Hz that modulated with PD.\n###figure_2###"

Figure 2  ###reference_### shows the frequency sensitivity of the pooling output layer which highlights that most of the pooling outputs were sensitive to the low-frequency range (<30 Hz) while many were also sensitive to the gamma range near 60 Hz (40-80 Hz).

Then, we observed the PSD of the convolutional layer\u2019s output channels which represent the frequency response of the filtering processes.

Additionally, there was a noticeable decline in performance as the kernel size increased, indicating that larger kernels may lead to reduced efficacy in feature extraction. This trend suggests that smaller kernels are more suitable for optimizing the performance of LightCNN in EEG-based PD classification. Notably, while most performance metrics deteriorated with larger kernels, the AUC exhibited minimal change, whereas recall metrics showed the greatest variability. This implies that models with larger kernels may develop class-specific biases, resulting in less balanced classification outcomes.\n###figure_4###"

Despite its simplicity, our model with a single convolutional layer demonstrated remarkable performance, surpassing state-of-the-art (SOTA) architectures across all evaluation metrics. This achievement underscores the potential of minimalist architectures to deliver superior results without the computational complexity often associated with more sophisticated models.\nAmong the SOTA architectures compared, CRNN emerged as the closest competitor, providing strong overall performance. However, our LightCNN model outperformed CRNN by significant margins: a 2.3% improvement in recall, a 4.6% increase in precision, a 4% boost in F1-score, and a 3.3% higher accuracy. These results highlight LightCNN\u2019s effectiveness in achieving a balanced and robust performance in all metrics. CRNN\u2019s use of a GRU layer, while effective, introduces substantial computational demands and challenges in scalability, particularly for large-scale or real-time applications. In contrast, LightCNN\u2019s architecture avoids these complexities, offering a more efficient and scalable alternative without compromising on performance. The simplicity of our approach not only facilitates easier implementation but also makes it more adaptable to scenarios where computational resources are constrained.\nOur investigation of LightCNN\u2019s features showed that it can capture the neurophysiological changes of EEG that have clinical relevance in PD. Specifically, the convolutional layer operates as a filter bank, isolating critical frequency components relevant to PD, while the pooling layer evaluates the signal strength within these frequencies. The fully connected layer then weights these frequency-specific signal strengths to perform the classification. The high classification performance of this simple architecture shows that indeed the frequency-specific contents captured by a single convolutional layer are powerful enough to analyze EEG signals for PD classification.\nOur findings have important implications. First, they demonstrate that a well-designed CNN architecture can effectively capture the necessary features for PD classification from EEG data, eliminating the need for more complex networks for EEG analysis. Indeed, our results showed an inverse relationship between the model\u2019s depth of layers and performance. Furthermore, our ablation study showed that the simpler version of LightCNN with a lower kernel size is better for PD classification. These indicate that while EEG data are complex in nature, this complexity does not warrant deep neural architectures. On the contrary, larger models tend to overfit and memorize EEG data. They also need larger training datasets which is not suitable for EEG-based analysis due to the scarcity of such datasets. Second, the performance gains achieved by LightCNN suggest that lightweight models can be both efficient and powerful, making them suitable for deployment in resource-limited environments, such as mobile or embedded systems. Third, simpler models are more interpretative and the features captured by such models have clinical relevance which is a key requirement in medical applications.\nFuture research could explore the generalizability of LightCNN to other neurodegenerative disorders or broader EEG-based classification tasks. Additionally, integrating techniques like model quantization or pruning could further enhance LightCNN\u2019s efficiency, making it an even more attractive option for real-time and edge computing applications."

+    "abstract": "Isosurface visualization is fundamental for exploring and analyzing 3D volumetric data. Marching cubes (MC) algorithms with linear interpolation are commonly used for isosurface extraction and visualization. Although linear interpolation is easy to implement, it has limitations when the underlying data is complex and high-order, which is the case for most real-world data. Linear interpolation can output vertices at the wrong location. Its inability to deal with sharp features and features smaller than grid cells\ncan lead to an incorrect isosurface with holes and broken pieces.\nDespite these limitations, isosurface visualizations typically do not include insight into the spatial location and the magnitude of these errors. We utilize high-order interpolation methods with MC algorithms and interactive visualization to highlight these uncertainties. Our visualization tool helps identify the regions of high interpolation errors. It also allows users to query local areas for details and compare the differences between isosurfaces from different interpolation methods. In addition, we employ high-order methods to identify and reconstruct possible features that linear methods cannot detect. We showcase how our visualization tool helps explore and understand the extracted isosurface errors through synthetic and real-world data.",

Statistical methods for parametric [2  ###reference_b2###] and nonparametric [41  ###reference_b41###, 3  ###reference_b3###] models provide measure metrics that can be used to visualize the most probable isosurface and its uncertainty. For instance, Athawale et al. provided a closed form for computing the expected position and variance of the level-crossing in the MC algorithm for parametric [2  ###reference_b2###] and nonparametric [3  ###reference_b3###] distributions. Topology case count and entropy-based methods can resolve ambiguity in MC algorithm and visualize isosurface uncertainty [4  ###reference_b4###]. The statistical approaches may require solving the level-set crossing problem for each cell many times or sampling methods such as Monte Carlo sampling algorithms that are computationally expensive [20  ###reference_b20###, 48  ###reference_b48###]. The closed forms in [2  ###reference_b2###, 3  ###reference_b3###, 4  ###reference_b4###] improve the computational performance for independent noise models, however, no closed forms are available for more complex noise models such as multivariate Gaussian noise models. The isosurface uncertainty characterized by the statistical methods relies on ensemble data and doesn\u2019t explicitly account for the uncertainty from the interpolation method (model uncertainty) which is the focus of this work.\nWhen the target isosurface is accessible, the uncertainty can be derived by computing the error between the target and approximated isosurfaces [11  ###reference_b11###, 1  ###reference_b1###].\nHowever, the error computation is computationally expensive as it relies on isosurface sampling, and the target isosurface is often unavailable."

Recently, machine learning-based approaches have been proposed for more accurate MC with feature preservation [10  ###reference_b10###, 16  ###reference_b16###, 9  ###reference_b9###, 42  ###reference_b42###, 18  ###reference_b18###].\nKobelt et al. [29  ###reference_b29###] propose a surface extraction method from directed distance field and surface normals of a geometric object that preserves sharp features. The normals are used to detect the sharp features and new sample points are added inside the cell to recover the hidden features. The Dual contouring algorithm proposed in [26  ###reference_b26###] uses the edges intersection and the normals at those intersections to process the cells with sharp features. This method doesn\u2019t explicitly require identifying the cell with sharp features because it uses a quadratic error function to automatically place the additional points. Ho et al. [23  ###reference_b23###] propose sampling the edges normals to detect the cell with sharp features in volumetric data. These cells are then subdivided to represent the sharp features. The adaptive refinement of the cell requires access to a finer-resolution version of the data."

The orange regions in Fig. 8  ###reference_### and Fig. 9  ###reference_### show the accuracy improvement from linear to higher order methods.\nMoreover, we introduced a hidden feature reconstruction method in Section 3.2  ###reference_### that successfully identifies and reconstructs possible features that are ignored by the MC algorithms. The extraction of these features is based on fitting and refining the target cells using cubic interpolation. The polygon extraction at the boundary of the refined and unrefined cells causes cracks that are resolved using a similar approach in  [29  ###reference_b29###], illustrated in Fig. 5  ###reference_###. we visualize the isosurfaces with (transparent orange) and without (opaque blue) to enable visual comparison of two possible isosurfaces from MC with different features and topological structures, as shown in Estimation and Visualization of Isosurface Uncertainty from Linear and High-Order Interpolation Methods. Figure 10  ###reference_### shows that our method for hidden feature reconstruction leads to a smoother connection between broken pieces compared to dual contouring which introduces sharp edges and corners.\nIt is important to note that the techniques introduced have some limitations that we plan to address as this work continues. Even though we didn\u2019t observe these issues in the datasets used, the cubic, WENO, and other high-order interpolation methods may introduce undesirable oscillations. These oscillations may be reduced without comprising the possible hidden features with bounded interpolation methods  [39  ###reference_b39###, 40  ###reference_b40###]. In addition, non-polynomial-based methods could provide more accurate error approximation for data that are generated from processes that don\u2019t rely on polynomials."

+            "text": "In this paper, we presented an efficient method for estimating and visualizing isosurface uncertainty from Marching Cubes (MC) algorithms. We introduce a closed-form approximation of edge-crossing error using polynomial interpolation and develop a technique for detecting and reconstructing uncertain hidden features. These approaches provide valuable insights into isosurface uncertainty and highlight the limitations of linear interpolation. In addition, we developed an integrated visualization system for the exploration and analysis of these uncertainties. Our examples and results demonstrate the effectiveness of our methods in estimating and visualizing isosurface uncertainty associated with linear interpolation.\nThis work focused on error estimations for linear, cubic, and WENO interpolation methods. Extending the error analysis to include higher-order polynomial and non-polynomial interpolation techniques in future work could further improve error characterization across a broader range of interpolation models. Additionally, the current framework visualizes errors and potential hidden features separately. Integrating these into a unified visualization could provide a more comprehensive analysis of isosurface uncertainty."

+    "title": "Toward Large-scale Spiking Neural Networks: A Comprehensive Survey and Future Directions",
+    "abstract": "Deep learning has revolutionized artificial intelligence (AI), achieving remarkable progress in fields such as computer vision, speech recognition, and natural language processing. Moreover, the recent success of large language models (LLMs) has fueled a surge in research on large-scale neural networks. However, the escalating demand for computing resources and energy consumption has prompted the search for energy-efficient alternatives. Inspired by the human brain, spiking neural networks (SNNs) promise energy-efficient computation with event-driven spikes. To provide future directions toward building energy-efficient large SNN models, we present a survey of existing methods for developing deep spiking neural networks, with a focus on emerging Spiking Transformers. Our main contributions are as follows: (1) an overview of learning methods for deep spiking neural networks, categorized by ANN-to-SNN conversion and direct training with surrogate gradients; (2) an overview of network architectures for deep spiking neural networks, categorized by deep convolutional neural networks (DCNNs) and Transformer architecture; and (3) a comprehensive comparison of state-of-the-art deep SNNs with a focus on emerging Spiking Transformers. We then further discuss and outline future directions toward large-scale SNNs.",

+            "text": "Deep learning has achieved significant accomplishments over the last decade [1  ###reference_b1###], demonstrating promising results that match or even surpass human performance across various fields such as computer vision [2  ###reference_b2###], speech recognition [3  ###reference_b3###], natural language processing (NLP) [4  ###reference_b4###], and go [5  ###reference_b5###, 6  ###reference_b6###]. Recently, large language models (LLMs), i.e., very deep neural networks based on Transformer architecture [7  ###reference_b7###] that contain hundreds of billions of parameters have attracted worldwide interest. Fueled by the success of ChatGPT [8  ###reference_b8###] (a large language model with remarkable communication abilities), the artificial intelligence (AI) community has witnessed a rapid expansion of research on large-scale neural networks throughout 2022 and 2023.\nAlthough deep neural networks (DNNs) demonstrate promising capabilities, the increasing demand for memory and computing resources poses a significant challenge to the development and application of DNNs, especially in resource-constrained environments such as edge computing applications. Additionally, the growing carbon footprint of DNNs also contributes to environmental problems such as global warming. For instance, GPT-3 reportedly used 1,287 MWh during training and OpenAI consumes approximately 564 MWh per day to run ChatGPT [9  ###reference_b9###]. In contrast, the human brain can perform a series of complex tasks with a power budget of about 20 Watts [10  ###reference_b10###]. To address the bottleneck of deep learning, researchers have drawn inspiration from human brain and proposed spiking neural networks (SNNs) [11  ###reference_b11###], which hold promise for achieving high energy efficiency.\nSpiking Neural Networks (SNNs). Different from traditional artificial neural networks (ANNs), SNNs are neural networks composed of spiking neurons that exchange information via discrete spikes (events that are either 0 or 1) rather than real-valued activations. Leveraging an event-driven computing model, spiking neurons in SNNs only update asynchronously upon the arrival of spikes. Additionally, compared to DNNs that heavily rely on multiply-and-accumulate (MAC) operations, SNNs employ less costly accumulate (AC) operations [10  ###reference_b10###]. Along with emerging neuromorphic hardware (e.g., TrueNorth [12  ###reference_b12###], Loihi [13  ###reference_b13###], and Darwin [14  ###reference_b14###]), SNNs hold promise for addressing the von Neumann bottleneck and achieving energy-efficient machine intelligence with massively parallel processing driven by spikes [15  ###reference_b15###].\nDevelopment. Due to the discontinuity of spikes, training SNNs has been challenging for powerful gradient descent algorithms are not directly applicable. In early works (e.g., SpikeProp [16  ###reference_b16###], Tempotron [17  ###reference_b17###], ReSuMe [18  ###reference_b18###], and unsupervised STDP [19  ###reference_b19###]), SNNs had limited capabilities due to the lack of effective learning algorithms. Inspired by the success of deep learning, researchers have developed various learning algorithms based on deep convolutional neural networks (DCNNs) since 2015, leading to significant improvements in complex tasks such as ImageNet classification [20  ###reference_b20###]. Recently, inspired by the success of LLMs, a new trend in SNN research has emerged: building deep SNNs based on Transformer architecture. Since Transformer blocks are a crucial and constant part of most LLM frameworks, combining Spiking Transformers with neuromorphic hardware could make significant progress toward alleviating the energy bottleneck of LLM inference by implementing large SNN models.\nScope. Focusing on deep neural networks, we limit the scope of our study to deep spiking neural networks, i.e., SNNs capable of performing complex tasks such as image classification on ImageNet [20  ###reference_b20###]. To this end, we primarily examine two aspects that are heavily studied and of great importance: learning rules and network architecture. For learning rules, we focus on two popular approaches: ANN-to-SNN conversion and direct training with surrogate gradients. For SNNs built with local plasticity rules such as STDP [21  ###reference_b21###] (e.g., [22  ###reference_b22###]), please refer to other surveys such as [23  ###reference_b23###]. For network architectures, we focus on two popular categories: DCNNs and Spiking Transformers.\nRelated Work. Spiking neural networks, especially their training methods, have been the subject of several recent surveys [24  ###reference_b24###, 25  ###reference_b25###, 26  ###reference_b26###, 27  ###reference_b27###, 28  ###reference_b28###]. In [24  ###reference_b24###], Yi et al. describe a range of learning rules for SNNs. Focusing on direct learning methods, Guo et al. present a survey on methods for accuracy improvement, efficiency enhancement, and temporal dynamics utilization. Dampfhoffer et al. [26  ###reference_b26###], concentrating on deep SNNs, review ANN-to-SNN conversion and backpropagation methods with a taxonomy of spatial, spatiotemporal, and single-spike approaches. Similarly, Eshraghian et al. [27  ###reference_b27###] explore how SNNs could leverage deep learning technologies. In [28  ###reference_b28###], Rathi et al. provide a systematic review of SNNs, covering both algorithms and hardware. However, none of these works provide a survey on emerging Spiking Transformer architectures, which hold the potential for achieving large-scale SNN models.\nPaper Overview. First, Section 2.1  ###reference_### surveys learning methods for building deep SNNs. Section 2.2  ###reference_### surveys network architectures for deep SNNs (e.g., DCNNs and Spiking Transformers). Section 2.3  ###reference_### compares state-of-the-art deep SNNs on the ImageNet benchmark.

This conversion method promotes transfer learning and fine-tuning while enhancing the biological plausibility of neural networks. The inherent sparsity and event-driven processing of SNNs align well with hardware implementations, fostering scalability and energy efficiency in neuromorphic computing.\nBased on the assumption that ANN activations approximate SNN firing rates, researchers proposed various conversion methods to exploit the advantages of deep neural networks and build deep SNNs by mapping real-valued activation neurons into discrete spiking neurons (Fig. 1  ###reference_###). Cao et al. [38  ###reference_b38###] first proposed to map CNNs with ReLU activations and no biases into SNNs of integrate-and-fire (IF) neurons. The ReLU function is defined by\nwhere  denotes weight and  denotes input activation. The IF neuron is defined by\nwhere  denotes output,  denotes the firing threshold,  denotes the membrane potential, and  is the Heaviside step function:\nThey demonstrated that the rectified linear unit (ReLU) function is functionally equivalent to integrate-and-fire (IF) neuron, i.e., LIF neuron with no leaky factor or refractory period:\nwhere  denotes the total number of time steps.\nTo improve the performance of converted SNNs, Diehl et al. [22  ###reference_b22###] examined the conversion process and reported over-/under-activation of spiking neurons that distorts the approximation between ANN activations and SNN firing rates. To address this problem, they proposed weight normalization and threshold balancing, which are mathematically equivalent.\nIn [39  ###reference_b39###], Rueckauer et al. performed a detailed analysis of ANN-to-SNN conversion. They found information loss due to the reset of spiking neurons and proposed using reset-by-subtraction or soft reset to replace the original reset-by-zero method. They further identified that quantization resulting from residual membrane potentials not integrated into spikes is a major factor degrading the performance of converted SNNs. To address this issue, they improved weight normalization [22  ###reference_b22###] by using the 99th or 99.9th percentile of activations instead of the maximum. Additionally, they implemented spiking versions of common operations in modern DCNNs (e.g., batch normalization), enabling the conversion of deeper CNNs.\nFollowing [22  ###reference_b22###] and [39  ###reference_b39###], several novel normalization methods have emerged to mitigate performance degradation after conversion. In [40  ###reference_b40###], Sengupta et al. proposed a dynamic threshold balancing strategy that normalizes SNNs at runtime. Building on [40  ###reference_b40###], Han et al. [41  ###reference_b41###] proposed scaling the threshold by the fan-in and fan-out of the IF neuron. Kim et al. [42  ###reference_b42###] introduced channel-wise weight normalization to eliminate extremely small activations and implemented Spiking-YOLO for object detection, which incorporates negative spikes to represent negative activations.\nTo improve the performance of converted SNNs, several interesting works have utilized fine-tuning after conversion. In [29  ###reference_b29###], Yan et al. proposed a framework to adjust pre-trained ANNs by incorporating knowledge of temporal quantization in SNNs. They introduced a residual term in ANNs to emulate the residual membrane potential in SNNs and reduce quantization error. In [31  ###reference_b31###], Wu et al. proposed a hybrid framework called progressive tandem learning to fine-tune full-precision floating-point ANNs with knowledge of temporal quantization.\nAiming to mitigate conversion errors that degrade the performance and increase the inference latency of converted SNNs, several works have further analyzed the conversion process and developed methods to facilitate ANN-to-SNN conversion. In [30  ###reference_b30###], Hu et al. proposed countering the accumulating error by increasing the firing rate of neurons in deeper layers based on statistically estimated error. In [32  ###reference_b32###], Deng et al. suggested training ANNs using capped ReLU functions, i.e., ReLU1 and ReLU2, and then applying a scaling factor to normalize the firing thresholds by the maximum activation of the capped ReLU function. In [33  ###reference_b33###], Li et al. introduced layer-wise calibration to optimize the weights of SNNs, correcting conversion errors layer by layer. Instead of optimizing synaptic weights, Bu et al. [34  ###reference_b34###] proposed optimizing the initial membrane potential to reduce conversion errors. In [35  ###reference_b35###], Bu et al. introduced a quantization clip-floor-shift activation function to replace ReLU, achieving ultra-low latency (4 time steps) for converted SNNs. Through an analysis of the equivalence between ANN quantization and SNN spike firing, Hu et al. [36  ###reference_b36###] proposed a mapping framework that facilitates conversion from quantized ANNs to SNNs. They also demonstrated a signed IF neuron model and a layer-wise fine-tuning scheme to address sequential errors in low-latency SNNs. In [37  ###reference_b37###], Li et al. proposed a set of layer-wise parameter calibration algorithms to tackle activation mismatch.\nIn Table I  ###reference_###, we summarize the state-of-the-art results of ANN-to-SNN conversion methods on the CIFAR-10, and ImageNet datasets."

This offers streamlined end-to-end learning, simplifying the training process of SNNs.\nTo address the discontinuous spiking function, researchers employ surrogate gradients (derivatives of continuously differentiable functions) to approximate the derivative of the spiking nonlinearity. For deep spiking neural networks, a popular method is to treat SNNs as recurrent neural networks (RNNs) with binary outputs and use backpropagation-through-time (BPTT) to train SNNs [62  ###reference_b62###, 27  ###reference_b27###]. Similar to the iterative application of the chain rule in RNNs, BPTT unrolls SNNs and propagates gradients from the loss function to all descendants. For example, synaptic weights can be updated using the following rule:\nwhere  denotes the loss,  denotes the output,  denotes the membrane potential,  denotes the synaptic weight,  denotes the total number of time steps. To circumvent the non-differentiable spiking mechanism,  is typically replaced by a differential surrogate gradient function to facilitate gradient backpropagation. Fig. 2  ###reference_### demonstrates a linear function for generating surrogate gradients:\nwhere  is the firing threshold and  is a constant.\n###figure_2### In early works, Zenke and Ganguli [63  ###reference_b63###] proposed a nonlinear voltage-based three-factor online learning rule using a fast sigmoid function as the surrogate gradient function. Wu et al. [64  ###reference_b64###] introduced a spatio-temporal backpropagation (STBP) framework to simultaneously consider both the spatial and timing-dependent temporal domains during network training. In [65  ###reference_b65###], Gu et al. proposed spatio-temporal credit assignment (STCA) for BPTT with a temporal-based loss function.\nResearchers have proposed various methods to address the slow convergence and performance degradation caused by the mismatch between surrogate gradients and true gradients. In [47  ###reference_b47###], Li et al. introduced a differentiable spike function with four parameters to control its shape, based on the estimated loss of the finite difference gradient (FDG). Guo et al. [49  ###reference_b49###] proposed adapting the shape of the surrogate gradient function during training by minimizing the information maximization loss (IM-Loss). Guo et al. [53  ###reference_b53###] developed RecDis-SNN, which rectifies the membrane potential distribution (MPD) to better align with the surrogate gradient function. Lian et al. [54  ###reference_b54###] introduced the learnable surrogate gradient (LSG), which adjusts the width of the surrogate gradient according to the distribution of the membrane potentials.\nTo exploit neuron dynamics and enhance the performance of SNNs, several works have introduced learnable parameters into neuron models. Rathi et al. [46  ###reference_b46###] introduced the leakage and threshold parameters in the leaky integrate-and-fire (LIF) neuron model for optimization. Fang et al. [43  ###reference_b43###] introduced the Parametric Leaky Integrate-and-Fire (PLIF) neuron, which incorporates the time constant as a learnable parameter. Wang et al. [51  ###reference_b51###] proposed learnable thresholding to optimize threshold values during training. Yao et al. [52  ###reference_b52###] developed the gated LIF model (GLIF), which integrates bio-inspired features into neuronal behavior.\nTo facilitate error backpropagation, several works have introduced normalization techniques. Inspired by batch normalization in CNNs, Wu et al. [66  ###reference_b66###] enhanced spatio-temporal backpropagation (STBP) with a neuron normalization technique. Zheng et al. [45  ###reference_b45###] proposed threshold-dependent batch normalization (tdBN) for STBP. Kim et al. [44  ###reference_b44###] introduced a batch normalization through time (BNTT) technique. Duan et al. [50  ###reference_b50###] developed temporal efficient batch normalization (TEBN), which rescales presynaptic inputs using time-specific learnable weights. Guo et al. [55  ###reference_b55###] proposed membrane potential batch normalization (MPBN), which adds an additional batch normalization layer before the firing function to normalize the membrane potential.\nTo better extract temporal features, several works have proposed attention mechanisms for SNNs. Yao et al. [60  ###reference_b60###] introduced a temporal-wise attention SNN (TA-SNN) to estimate the saliency of each frame and process event streams efficiently. Yu et al. [61  ###reference_b61###] proposed a Spatio-Temporal Synaptic Connection SNN (STSC-SNN) model that incorporates temporal convolution and attention mechanisms for synaptic filtering and gating functions. In [59  ###reference_b59###], Yao et al. presented a multi-dimensional attention module that infers attention weights along the temporal, channel, and spatial dimensions, either separately or simultaneously. Lian et al. [57  ###reference_b57###] introduced an IM-LIF neuron model that utilizes a temporal-wise attention mechanism to adjust the synaptic current equation.\nDemonstrating that the incorrect surrogate gradient makes the SNN easily trapped into a local minimum with poor generalization, Deng et al. TET [48  ###reference_b48###] proposed temporal efficient training (TET) to compensate for the loss of momentum in the gradient descent with surrogate gradient. Following [48  ###reference_b48###], Mukhoty et al. [58  ###reference_b58###] proposed to address the loss of gradient information with zeroth-order technique at the local or neuron level.\nTo exploit the knowledge of ANNs, researchers have proposed hybrid training and knowledge distillation. Hybrid training [46  ###reference_b46###] circumvents the high training costs of backpropagation by using SNNs converted from ANNs for initialization. This method allows for the training of deep SNNs with limited resources and achieves high performance more quickly than random initialization. In contrast, knowledge distillation [56  ###reference_b56###] employs teacher ANNs to enhance the performance of SNNs trained with surrogate gradients.\nIn Table II  ###reference_###, we summarize the state-of-the-art results of direct training methods on the CIFAR-10, DVS CIFAR10, and ImageNet datasets.\n###figure_3### ###figure_4### ###figure_5###"

[38  ###reference_b38###] demonstrated that convolutional neural networks (CNNs) with ReLU activation functions can be mapped to spiking neural networks (SNNs) with integrate-and-fire (IF) neurons. In this framework, convolution and pooling operations in artificial neural networks (ANNs) can be interpreted as different patterns of synaptic connections in SNNs. Consequently, SNNs can be seen as CNNs with spiking neurons serving as activation functions, which paved the way for building deep SNNs with DCNN architectures. Esser et al. [69  ###reference_b69###] further showed that batch normalization (BN) can be integrated into the firing function during inference. This development facilitates the construction of deep SNNs with DCNN architectures, as batch normalization is a commonly used technique for training DCNNs efficiently. Consequently, popular ANN architectures such as AlexNet [2  ###reference_b2###], VGG [70  ###reference_b70###], and ResNets [71  ###reference_b71###] have become widely employed in SNNs.\nIn the search for deep SNN architectures, the ResNet architecture [71  ###reference_b71###] has garnered attention for its effective mitigation of the gradient exploding/vanishing problem. In [30  ###reference_b30###], Hu et al. demonstrated an ANN-to-SNN conversion method for converting the residual structure and reported that ResNets facilitate conversion by generating lower conversion errors compared to plain networks of the same depth. In [67  ###reference_b67###], Fang et al. proposed the spike-element-wise ResNet (SEW-ResNet), which replaces the standard residual structure with an activation-before-addition approach, allowing spiking neurons to fire positive integer spikes. While this modification enhances the representation capability of spikes, it also diminishes the advantages of event-driven computation. In [68  ###reference_b68###], Hu et al. introduced the membrane-shortcut ResNet (MS-ResNet), incorporating the pre-activation structure found in ANNs. This approach features a shortcut path that directly propagates the full-precision membrane potential of spiking neurons to all subsequent residual blocks. However, this hybrid structure of ANNs and SNNs also reduces the benefits of event-driven computation. Fig. 3  ###reference_### visualizes these three different implementations of shortcuts.\nIn contrast to the manually designed architectures mentioned above, several works have proposed using neural architecture search (NAS) to automatically discover optimal architectures for SNNs. Kim et al. [72  ###reference_b72###] introduced SNASNet, which simultaneously searches for both feed-forward and backward connections. Na et al. [73  ###reference_b73###] developed AutoSNN, a spike-aware NAS framework designed to effectively explore SNNs within a defined energy-efficient search space. Yan et al.

With the recent success of large language models (LLMs), research on deep SNNs with transformer architectures has become a focal point in the neuromorphic computing community.\n1) Vanilla Self-attention: Early works often utilized hybrid structures combining ANN-based self-attention modules with spiking components. For instance, Mueller et al. [75  ###reference_b75###] proposed a spiking transformer using the conversion method by Rueckauer et al. [39  ###reference_b39###]. Zhang et al. [76  ###reference_b76###] introduced a spiking transformer for event-based single object tracking, employing SNNs for feature extraction while retaining real-valued transformers. Similarly, Zhang et al. [77  ###reference_b77###] developed a model integrating transformers to estimate monocular depth from continuous spike streams generated by spiking cameras. However, these methods, using vanilla self-attention mechanisms, face challenges in fully leveraging the event-driven nature of SNNs and in reducing resource consumption.\n###figure_6### C - Conversion; DT - Direct Training\n2) Spiking Self-attention: A notable breakthrough was made by Zhou et al. [78  ###reference_b78###]. For the first time, they introduced a spiking self-attention mechanism and proposed a framework, i.e., Spikformer, to build deep SNNs with a transformer architecture. In contrast to vanilla self-attention [7  ###reference_b7###], spiking self-attention (Fig. 4  ###reference_###) discards the complex softmax operation, which is difficult to replace with spiking operations, and performs matrix dot-product on the spike forms of Query (Q), Key (K), and Value (V). On ImageNet, Spikformer achieves an accuracy of 74.81% with Spikformer-8-768 architecture and 4 time steps. However, there is still a performance gap between ANNs (Transformer-8-512 achieves an accuracy of 80.80%) and SNNs (Spikformer-8-512 achieves an accuracy of 73.38%).\nFollowing [78  ###reference_b78###], several works have explored the implementation of self attention mechanism in spiking transformers. In [80  ###reference_b80###], Yao el al. introduced Spike-driven Transformer and Spike-Driven Self-Attention (SDSA) that exploits mask and addition operations only for implementing self-attention. Shi et al. [105  ###reference_b105###] proposed Dual Spike Self-Attention (DSSA) that is compatible with SNNs to efficiently handle multi-scale feature maps. In [104  ###reference_b104###], zhou et al. developed Q-K attention mechanism that only adopts two spike-form components: Query (Q) and Key (K).\nAiming to enhance spiking transformers with spatio-temporal attention, several studies have introduced spatio-temporal self-attention mechanisms. Xu et al. [95  ###reference_b95###] proposed the Denoising Spiking Transformer with Intrinsic Plasticity and Spatio-Temporal Attention (DISTA), which integrates neuron-level and network-level spatiotemporal attention. They also introduced a non-linear denoising layer to mitigate noisy signals within the computed spatiotemporal attention map. To exploit both temporal and spatial information, Wang et al. [88  ###reference_b88###] developed Spatial-Temporal Self-Attention (STSA), enabling spiking transformers to capture features from both domains. They incorporated a spatial-temporal relative position bias (STRPB) to infuse the spatiotemporal position of spikes, integrating STSA into their Spatial-Temporal Spiking Transformer (STS-Transformer). For tracking human poses from purely event-based data, Zou et al. [81  ###reference_b81###] proposed an architecture combining a Spike-Element-Wise (SEW) ResNet as the backbone with a Spiking Spatiotemporal Transformer based on spiking spatiotemporal attention. To better exploit temporal information, Shen et al. [96  ###reference_b96###] introduced a Temporal Interaction Module (TIM) that integrates into the Spikformer [78  ###reference_b78###] framework, improving performance with minimal additional parameters through a one-dimensional convolution. Gao et al. [113  ###reference_b113###] also proposed capturing meaningful temporal information with a Spike Spatio-Temporal Attention (SSTA) module and replacing Batch Normalization (BN) with Batch Group Normalization (BGN) to balance firing rates across temporal steps.\nAiming to exploit frequency representations, Fang et al. [114  ###reference_b114###] proposed the Spiking Wavelet Transformer (SWformer). This model incorporates negative spikes and a Frequency-Aware Token Mixer (FATM) designed to extract both spatial and frequency features effectively.\n3) Enhancing Performance:\nTo improve network performance, several works have focused on optimizing network structure. Zhou et al. [93  ###reference_b93###] proposed Spikingformer, which modifies Spike-Element-Wise (SEW) shortcuts [43  ###reference_b43###] to use membrane shortcuts, avoiding integer spikes. Zhou et al. [94  ###reference_b94###] introduced ConvBN-MaxPooling-LIF (CML) to enhance downsampling modules in deep SNNs, facilitating gradient backpropagation compared to ConvBN-LIF-MaxPooling. To further improve Spikformer [78  ###reference_b78###], Zhou et al. [97  ###reference_b97###] developed Spikformer V2, incorporating a Spiking Convolutional Stem (SCS). Similarly, Li et al. [100  ###reference_b100###] proposed a Convolutional Tokenizer (CT) module for patch embedding. In [98  ###reference_b98###], Yao et al. introduced Spike-driven Transformer V2 with a meta-architecture to enhance performance and versatility. Zhang et al. [111  ###reference_b111###] proposed the Spiking Global-Local-Fusion Transformer (SGLFormer), designed to efficiently process information on both global and local scales, and introduced a new max pooling module and classification head.\nThere are also works focusing on reducing complexity. Wang et al. [91  ###reference_b91###] proposed AutoST, a training-free neural architecture search method for identifying optimal spiking transformer architectures. By emphasizing FLOPs, this method provides a standardized and objective assessment of model efficiency and computational complexity. Wang et al. [82  ###reference_b82###] aimed to reduce time complexity in Spikformer [78  ###reference_b78###] by replacing spiking self-attention with unparameterized Linear Transforms (LTs), such as Fourier and Wavelet transforms. Wang et al. [92  ###reference_b92###] introduced the Masked Spiking Transformer (MST) framework, incorporating a Random Spike Masking (RSM) method to reduce the number of spikes. Datta et al. [87  ###reference_b87###] proposed a training framework that dynamically allocates the number of time steps to each Vision Transformer (ViT) module based on a trainable score assigned to each timestep, hypothesizing that each ViT block has varying sensitivity to the number of time steps. To address the spatio-temporal overhead of Spiking Transformers, Song et al. [112  ###reference_b112###] introduced a Time Domain Compression and Compensation (TDCC) component and Spiking Linear Transformation (SLT) for implementing the One-step Spiking Transformer (OST).\nTo avoid the burdensome cost of training from scratch, some works employ ANN-to-SNN conversion to build Spiking Transformers. Wang et al. [92  ###reference_b92###] proposed to build Spiking Transformers based on ANN-to-SNN conversion with quantization clip-floor-shift (QCFS) [35  ###reference_b35###]. To address non-linear mechanisms like self-attention and test-time normalization in vanilla Transformers, Jiang et al. [107  ###reference_b107###] proposed Spatio-Temporal Approximation (STA) to approximate floating-point values in ANNs by introducing new spiking operators and layers. In [108  ###reference_b108###], You et al. proposed to facilitate Transformer-based ANN-to-SNN conversions with quantized ANNs that incorporate SNN-friendly operators. To preserve the accuracy after conversion, Huang et al. [109  ###reference_b109###] proposed a expectation compensation module that uses information from the previous T time steps to calculate the expected output at time step T. In addition, they also introduced a multi-threshold neuron model and a corresponding parallel parameter normalization to reduce time steps needed for high accuracy. On ImageNet, they reported 88.60% accuracy under 4 time steps, using a model with 1 billion parameters.\n3) Spiking Transformers for Natural Language Processing\nIn pursuit of spiking large language models (LLMs), several works explored Spiking Transformers for natural language processing (NLP). Zhu et al. [86  ###reference_b86###] proposed SpikingGPT for language generation based on Receptance Weighted Key Value (RWKV) language model. Replacing self attention with RWKV, they proposed a structure that employs the Spiking Receptance Weighted Key Value (Spiking RWKV) as a token-mixer and the Spiking Receptance Feed-Forward Networks (Spiking RFFN) as a channel mixer. In [85  ###reference_b85###], Bal et al. proposed SpikingBERT by combine spiking transformers with BERT. To effectively train their SpikingBERT, they proposed to employ a pre-trained BERT model as \u201cteacher\u201d to train their \u201cstudent\u201d spiking architecture. Similarly, Lv et al. [84  ###reference_b84###] modified Spikformer [78  ###reference_b78###] with respect to BERT and introduced SpikeBERT. To improve performance of Spiking BERT, they also proposed a two-stage, \u201cpre-training + task-specific\u201d knowledge distillation method to transfer knowledge from BERTs to SpikeBERT. In [110  ###reference_b110###], Zhange el al. also proposed a SpikingMiniLM based on BERT with a parameter initialization and ANN-to-SNN distillation method to achieve fast convergence. With a novel spike-driven quantization framework named Optimal Brain Spiking, Xing et al. [106  ###reference_b106###] proposed bio-plausible SpikeLLM that supports 7 70 billion parameters.\n4) Beyond Image Classification and Natural Language Processing\nCurrently, computer vision is the most explored field for Spiking Transformers. Although most works focus on image classification to design and evaluate Spiking Transformers, there are also works exploring their versatility. In computer vision, researchers have applied Spiking Transformers to object detection [98  ###reference_b98###], semantic segmentation [98  ###reference_b98###], zero-shot classification [83  ###reference_b83###], image generation [101  ###reference_b101###], etc.\nIn addition, researchers have also explored multidisciplinary applications for Spiking Transformers. For example, Guo et al. [79  ###reference_b79###] proposed Spiking Multi-Model Transformer (SMMT) for multimodel classification. Liu et al. [99  ###reference_b99###] proposed Spiking-PhysFormer for remote photoplethysmography. Chen et al. [102  ###reference_b102###] proposed Spiking Conformer to detect and predict epileptic seizure segments from scalped long-term electroencephalogram (EEG) recordings.\nIn Table III  ###reference_###, we summarize the evaluation tasks and datasets of existing Spiking Transformers. This table provides an overview of how these models have been assessed across various domains and applications.\nInputs are spike trains of 4 time steps, compressed to 1 time step inside the pipeline."

For each method, we present the result obtained by the model with highest classification accuracy. As is shown in the table, the performance of deep SNNs has improved significantly over the past few years, approaching the state-of-the-art performance of ANNs. In early years, pioneering deep SNNs on ImageNet usually employ ANN-to-SNN conversion methods to build deep models. However, although methods such as [40  ###reference_b40###, 41  ###reference_b41###] can achieve comparable performance to their ANN counter parts, they also require a latency of thousands of time steps that would effectively negate the energy advantage of SNNs and obstruct the potential application of SNNs in real-time scenarios. To address this problem, researchers have developed effective ANN-to-SNN conversion methods and direct training methods that can infer in just several time steps while maintaining comparable performance to ANNs. Meanwhile, it is also worth noting that there is still a performance gap between SNNs with a single time step for inference, which is analog to binary neural networks (BNNs) and ANNs. Besides, modern deep SNNs usually achieve state-of-the-art performance with 4 time steps, which effectively resembles a 2-bit quantization and coincides with findings in network quantization [115  ###reference_b115###]. Therefore, how to conserve maximal information with a minimal latency in SNNs remains a valuable research topic. Ignited by Spikformer [78  ###reference_b78###], research on deep SNNs with Transformer architecture is also booming. Although Spikformer [78  ###reference_b78###] suffers a performance gap between SNNs and their corresponding ANNs (73.38% accuracy of SNN Spikformer-8-512 vs. 80.80% accuracy of ANN Transformer-8-512), performance of deep SNNs is catching up with state-of-the-art ANNs. In Fig. 5  ###reference_###, we further demonstrate the performance of typical Spiking Transformers with respect to the size of models. The recent announced QKFormer [104  ###reference_b104###] achieves 84.22% accuracy, which is comparable to an ANN baseline reported in [116  ###reference_b116###] that employs no external data nor distillation. In Table V  ###reference_###, we also summarize the implementation details of typical Spiking Transformers trained from scratch."

Recently, the development of Spiking Transformers, which incorporate spiking self-attention, has significantly advanced this field. However, issues such as information loss and gradient vanishing in deep layers still limit the scalability of deep SNNs due to binary spike signals. Additionally, there is a lack of methods to efficiently utilize the temporal gradient information inherent in the recurrent nature of SNNs. We can anticipate many research efforts aimed at addressing these challenges."

For instance, equilibrium propagation utilizes the dynamics of the system for learning, while the Forward-Forward approach employs contrastive learning by feeding both the sample and its corresponding target into the network.

Research into neuron modeling, structural plasticity, and the role of dendrites shows promise for incorporating more sophisticated brain-like behaviors. Additionally, while gradient backpropagation relies on global plasticity, this contrasts with the local plasticity rules observed in neurobiology. Introducing local synaptic plasticity could enhance the learning capabilities of SNNs.

+    "abstract": "This study introduces a dataset consisting of approximately 9,000 images of mechanical mechanisms and their corresponding descriptions, aimed at supporting research in mechanism design. The dataset consists of a diverse collection of 2D and 3D sketches, meticulously curated to ensure relevance and quality. We demonstrate the application of this dataset by fine-tuning two models: 1) Stable Diffusion (for generating new mechanical designs), and 2) BLIP-2 (for captioning these designs). While the results from Stable Diffusion show promise, particularly in generating coherent 3D sketches, the model struggles with 2D sketches and occasionally produces nonsensical outputs. These limitations underscore the need for further development, particularly in expanding the dataset and refining model architectures. Nonetheless, this work serves as a step towards leveraging generative AI in mechanical design, highlighting both the potential and current limitations of these approaches.",

+            "text": "Mechanical mechanism design has traditionally followed a structured approach, beginning with engineers identifying a problem, followed by exploring and analyzing existing mechanisms to directly apply to or inspire solutions. This method, while effective, can be time-consuming and limited by the scope of known mechanisms. We propose that generative AI models hold remarkable potential for a paradigm shift in how mechanical mechanisms are conceived. These AI tools can assist in generating novel mechanism ideas or aid in the brainstorming phase, potentially expediting and streamlining the design process. Although some text-to-image generation tools, such as DALL-E and Midjourney, are already available, these tools are generally not fine-tuned for mechanical systems. Consequently, they often generate outputs with limited relevance for engineering design, underscoring the need for specialized datasets that can be used for fine-tuning or training these models.\nThis work presents a dataset of  9,000 images of mechanical mechanisms (2D and 3D sketches), each accompanied by a text description. To evaluate the utility of this dataset, we used it in training models which were then used in generating new mechanism and in developing image captioning models. This work provides a specialized dataset for the research community, and illustrates the potential of AI-driven approaches in advancing mechanical design processes."

For each mechanism, we extracted a frame from the video along with its description. The second source was a digital library dedicated to mechanisms and gears [1  ###reference_b1###], which included a video section featuring 3D reconstructions. These videos provided detailed visualizations of mechanisms, from which we extracted images and descriptions (Table 1  ###reference_###). The third source was a book that contains a vast collection of 2D sketches and comprehensive descriptions of mechanical mechanisms [2  ###reference_b2###]. In total, these sources yielded 8,994 images and corresponding descriptions.\nTo ensure the quality of the dataset, we conducted a thorough manual review of all the images. During this process, we identified and removed any images that were blank, irrelevant, or did not make sense. To clean up descriptions, we manually edited them to ensure consistency and relevance. We used ChatGPT to remove references to patents/designs, creators\u2019 names, or other verbose and/or unrelated content by providing specific instructions to remove any such references, including mentions of detailed variants or referrals to other designs.\n###table_1###"

+    "abstract": "The perception of autonomous vehicles has to be efficient, robust, and cost-effective. However, cameras are not robust against severe weather conditions, lidar sensors are expensive, and the performance of radar-based perception is still inferior to the others. Camera-radar fusion methods have been proposed to address this issue, but these are constrained by the typical sparsity of radar point clouds and often designed for radars without elevation information. We propose a novel camera-radar fusion approach called Dual Perspective Fusion Transformer (DPFT), designed to overcome these limitations. Our method leverages lower-level radar data (the radar cube) instead of the processed point clouds to preserve as much information as possible and employs projections in both the camera and ground planes to effectively use radars with elevation information and simplify the fusion with camera data. As a result, DPFT has demonstrated state-of-the-art performance on the K-Radar dataset while showing remarkable robustness against adverse weather conditions and maintaining a low inference time. The code is made available as open-source software under https://github.com/TUMFTM/DPFT.",

These conditions include everyday driving situations such as nighttime driving or driving under severe weather conditions, but also critical situations where the autonomous vehicle (AV) has to react quickly or maintain general functionality after a sensor failure.\nThe perception of most autonomous driving systems is based on either camera or light detection and ranging (lidar) sensors. While camera sensors are cost-effective, they depend on ambient light and do not provide depth information [1  ###reference_b1###]. In contrast, lidar sensors provide accurate measurements of the surroundings but come at a high cost. More importantly, neither camera nor lidar sensors are robust against severe weather conditions like rain, fog, or snow [2  ###reference_b2###]. On the other hand, radio detection and ranging (radar) sensors are cost-effective and robust against challenging environmental conditions but do not yet provide comparable object detection qualities as lidar or camera-based perception methods due to their low spatial resolution and high noise level [3  ###reference_b3###].\nA potential solution to overcome the limitations of individual sensor technologies is the combination of multiple sensor modalities, also referred to as sensor fusion. Nevertheless, sensor fusion remains challenging due to inherent differences between the camera and radar sensors, such as the perceived dimensionality (2D vs. 3D), data representation (point cloud vs. grid), and sensor resolution [4  ###reference_b4###].\n###figure_1### In this paper, we propose a novel camera and radar sensors fusion method to provide a robust, performant, yet cost-effective method for 3D object detection. While camera-radar fusion has been done before [4  ###reference_b4###], previous methods mostly rely on radar point cloud data, thus suffering from a sparse data representation and facing the challenge of combining images with point clouds. On the other hand, fusion approaches that utilize raw radar data solely rely on radar data in a bird\u2019s eye view (BEV) representation. Therefore, they are fusing data from the image plane with data from a perpendicular BEV plane on one side and discarding the advantages of modern 4D radar sensors on the other.\nOur proposed method overcomes these limitations by fusing camera data with raw radar cube data to mitigate the differences in sensor resolution and benefit from a structured grid representation for both sensor modalities. However, directly consuming the raw radar cube would be unfeasible due to its high demand for computational resources. Therefore, we developed a projection method that reduces the 4D radar cube to two 2D grids while maintaining important features and providing a low sensitivity to input noise. As a result, the proposed fusion architecture utilizes radar data from both a BEV and a front-view perspective as shown in Figure 1  ###reference_###. With this dual perspective approach, we create a corresponding data source to the image plane to support camera-radar fusion and incorporate data from the BEV plane to exploit all radar dimensions. All three data inputs are then fed through a ResNet feature extractor and subsequent Feature Pyramid Network (FPN) neck before they are combined in the fusion module. However, our method does not require a combined feature space but queries 3D objects directly from these individual perspectives, thus preventing the loss of information caused by a uniform feature space or raw data fusion [5  ###reference_b5###]. To enable this, we introduce a modified deformable attention [6  ###reference_b6###] mechanism that allows both cartesian and spherical reference point projection to realize a modality-agnostic sensor fusion.\nIn summary, our main contributions are three-fold:\nWe propose an efficient sensor fusion approach that projects the radar cube onto two perspectives, thus simplifying the camera-radar fusion, avoiding the limitations of sparse radar point clouds, and leveraging the advantages of 4D radar sensors.\nWe are the first to fuse 4D radar cube data with image data by proposing a novel fusion method that does not rely on a common BEV representation to fuse camera and radar data.\nExperiments show that our method achieves state-of-the-art results in severe weather conditions on the challenging K-Radar dataset thus offering greater robustness and lower inference times than previous methods."

Out of those, pseudo-lidar methods [19  ###reference_b19###] are most commonly used to transform camera images into 3D point clouds. Besides that, learning-based approaches [20  ###reference_b20###] can be used for data lifting, and even most feature lifting methods [21  ###reference_b21###, 22  ###reference_b22###] can directly be applied to image data.\nFeature lifting methods first extract 2D image features, which are then lifted into 3D space to serve as the basis for the prediction of 3D objects [17  ###reference_b17###]. Within this category, there are two dominant lifting strategies: one \u201dpushes\u201d (splatting) the features from 2D into 3D space [21  ###reference_b21###] and the other \u201dpulls\u201d (sampling) the 3D features from the 2D space [22  ###reference_b22###].\nResult lifting methods are characterized by the fact that they first estimate the properties of the objects in the 2D image plane and then lift the 2D detections into 3D space [17  ###reference_b17###]. Inspired by the taxonomy used within the field of 2D object detection, these methods can be further divided into one-stage and two-stage detectors. One-stage detectors regress 3D objects directly from 2D image features and are typically characterized by fast inference speeds. Representative methods of this category are anchor-based detectors [23  ###reference_b23###] or anchor-free models like [24  ###reference_b24###]. Two-stage detectors first generate region proposals before they refine those proposals to predict 3D objects [17  ###reference_b17###]. Methods from this category can use either geometric priors [25  ###reference_b25###, 26  ###reference_b26###] or model-based priors [27  ###reference_b27###].\nEven if different strategies have been developed over the years, the biggest challenge for camera-based 3D object detection remains the lifting from 2D to 3D space due to the inability of camera sensors to directly measure depth information [1  ###reference_b1###]. Furthermore, camera sensors are susceptible to illumination changes and severe weather conditions [1  ###reference_b1###], limiting their robustness in field applications."

This is due to the fact that radar sensors perceive their environment by actively emitting radio wave signals and analyzing their responses [4  ###reference_b4###]. However, this analysis requires multiple processing steps, which is why radar-based 3D object detection methods are categorized by the data level they are operating on [3  ###reference_b3###]. The first category of methods operates directly on the raw analog-to-digital converted (ADC) radio wave signals. These ADC signals are then converted from the temporal to the spatial domain using a Discrete Fast Fourier Transformation (DFFT). The resulting data representation is a discrete but dense radar cube and the basis for the second type of detection methods. Finally, this data can be further reduced by only considering data points with high response values, leading to a spare point cloud representation and the input to the third (and most common) type of methods [4  ###reference_b4###].\nMethods operating on the raw ADC signals are rare due to limited data availability, high memory requirements, and the abstract data format. Even if Yang et al. [28  ###reference_b28###] achieved promising results on the RADIal [15  ###reference_b15###] dataset, Liu et al. [3  ###reference_b3###] showed that ADC data has no advantages over radar cube data. Thus, the benefits of replacing the DFFT with a neural network remain questionable.\nDetection methods utilizing cube-level radar data can be subdivided into those using 2D, 3D, or 4D radar data. Methods utilizing 2D radar data use either range-azimuth (RA) [29  ###reference_b29###, 30  ###reference_b30###, 31  ###reference_b31###] or range-doppler (RD) [32  ###reference_b32###, 33  ###reference_b33###] measurements, while 3D methods either use multiple 2D projections [34  ###reference_b34###, 35  ###reference_b35###] or the whole range-azimuth-doppler (RAD) cube [36  ###reference_b36###, 37  ###reference_b37###]. However, none of the above mentioned methods are used for 3D, but only 2D object detection, and neither of those utilizes the elevation information of modern 4D (3+1D) radar sensors.\nMethods relying on radar point clouds are the most common type of detectors and can be further divided into grid, graph, and point-based methods. Grid-based methods [38  ###reference_b38###, 39  ###reference_b39###, 40  ###reference_b40###, 41  ###reference_b41###] discretize the point cloud space to derive a regular grid from the sparse point cloud. Graph-based methods [42  ###reference_b42###, 43  ###reference_b43###, 44  ###reference_b44###] create connections (edges) between the points (vertices) to utilize graph neural networks (GNNs) for object detection tasks. Lastly, point-based methods [45  ###reference_b45###, 46  ###reference_b46###, 47  ###reference_b47###, 48  ###reference_b48###, 49  ###reference_b49###] use specialized network architectures to directly detect objects within the sparse irregular radar point clouds.\nGenerally, radar-based object detection methods are robust against severe weather conditions but do not yet achieve competitive performance values. This is mainly due to the radar\u2019s lower spatial resolution, higher noise level, and limited capability to capture semantic information."

These fusion methods can be divided into data-level, object-level, and feature-level fusion methods.\nData-level fusion aims to directly combine the raw data from both sensor modalities. Following this approach, Nobis et al. [50  ###reference_b50###] was the first to propose a camera-radar fusion model that projected the radar points into the camera image and used a hierarchical fusion strategy to regress objects from it. On the other side, Bansal et al. [51  ###reference_b51###] projected the semantic information of the camera image onto the radar point cloud (similar to PointPainting [52  ###reference_b52###]) and detected objects within the enriched radar data. Nevertheless, data-level fusion is associated with a high loss of information due to the differences in sensor resolution [5  ###reference_b5###] and challenging due to different data representations and dimensionalities.\nObject-level fusion addresses these challenges by using two separate networks for both modalities independently and only combining their detection outputs. Using this technique, Jha et al. [53  ###reference_b53###] fused 2D objects from a camera and radar branch, while Dong et al. [54  ###reference_b54###] combined an object-level with a data-level fusion approach to detect 3D objects on a proprietary dataset. Most recently, Zhang et al. [55  ###reference_b55###] fused the outputs of a radar-based method [37  ###reference_b37###] with the detections of a camera-lidar fusion method and achieved state-of-the-art results on the K-Radar dataset [16  ###reference_b16###]. However, their method, solely relying on camera and lidar data, outperformed the radar fusion method only slightly, thus showing that the capabilities of object-level fusion are limited. This is because object-level fusion exclusively depends on the final detection outputs, neglecting any intermediate features [4  ###reference_b4###]. As a result, the final detection quality relies heavily on the performance of the individual modules and does not fully utilize complementary sensor features [4  ###reference_b4###].\nFeature-level fusion aims to combine the advantages of both methods by first extracting features from each modality separately, fusing them at an intermediate level, and finally predicting objects based on their combined feature space. Therefore, it allows to address individual sensor aspects and benefits from a combination of their unique properties. However, finding a suitable feature space to combine both modalities remains challenging. Besides early attempts to combine region proposals from camera and radar branches [56  ###reference_b56###, 57  ###reference_b57###, 58  ###reference_b58###] or feature-level fusion on the image plane [59  ###reference_b59###, 60  ###reference_b60###], most recent methods focus on a bird\u2019s eye view (BEV) feature representation.\nUsing a BEV feature representation, Harley et al. [22  ###reference_b22###] proposed a method to combine rasterized (\u201dvoxelized\u201d) radar point cloud data with camera data and outperformed their camera baseline on the nuScenes [7  ###reference_b7###] dataset. Similarly, Zhou et al. [61  ###reference_b61###] fused rasterized and temporally encoded radar point cloud data with image data in the BEV space and reported an increased detection quality. However, both methods utilize only 3D radar data, not considering modern 4D radar sensors. Addressing this issue, both Xiong et al. [62  ###reference_b62###] as well as Zheng et al. [63  ###reference_b63###] proposed a method to fuse camera and 4D radar point cloud data in a BEV space. While achieving good results on the TJ4DRadSet [11  ###reference_b11###] and View-of-Delft [10  ###reference_b10###] dataset, these methods solely rely on radar point cloud data. However, radar point cloud data is not only difficult to fuse due to its irregular, sparse data structure but also contains significantly less information, which is lost during signal processing and adverse to accurate environment perception [64  ###reference_b64###].\nTo prevent this loss of information, Liu et al. [3  ###reference_b3###] proposed a method to fuse raw radar data with camera image data, similar to our approach. However, their method relies on an intermediate BEV representation, which increases the demand on computational resources and limits their ability to encode various 3D structures [65  ###reference_b65###]. Moreover, their method does not utilize the elevation information of modern 4D radar sensors, but solely relies on radar data in the range-azimuth (BEV) plane. To overcome these limitations, we propose a novel method that does not require a uniform feature representation and exploits all radar dimensions."

Camera sensors capture the environment as a projection onto the 2D image plane, while radar sensors typically capture measurements in the range-azimuth (BEV) plane. Broadly speaking, these two perception planes are perpendicular to one another, which makes them difficult to fuse due to their small intersection. To counteract this, our method is built on 4D radar data with three spatial dimensions and one Doppler dimension. This allows us to create a physical relationship between the two data sources. However, working with 4D data is not ideal for two reasons. First, lifting camera data into 3D space is challenging due to the missing depth information, and second, processing high dimensional data has a high demand on computational resources. Resolving this dilemma, the radar data is projected onto the range-azimuth plane as well as the azimuth-elevation plane. This way, we can create a complementary data source to the camera data while reducing the data size and creating a physical relationship between the image and the BEV plane to regress 3D objects.\nTo address the challenges associated with diverging data formats and sensor resolutions, our method is based on raw (cube-level) radar data. Usually, radar data is given as an irregular, sparse point cloud with a few hundred points per sample, while camera data is represented in a structured grid format with millions of pixels. Not only is it difficult to fuse these two data formats, but a fusion is also associated with a high loss of information or computational overhead [5  ###reference_b5###]. Furthermore, radar point clouds are the results of a multistage signal processing chain (explained in Section II  ###reference_###) during which a lot of information is lost and which deteriorates perception performance [3  ###reference_b3###]. Therefore, our method utilizes raw (cube-level) radar data, avoiding the loss of information, creating a uniform data representation, and lowering the differences in data resolution.\nFollowing this idea, the 4D radar cube is projected onto the range-azimuth (RA) and azimuth-elevation (AE) plane. However, to avoid the loss of important information and minimize the sensitivity to input noise, the design of the projection (dimensional reduction) follows a three-step process. First, a set of 30 initial radar features was defined that were proven to be significant to radar-based perception by previous studies [66  ###reference_b66###, 67  ###reference_b67###]. Secondly, a model was trained on all 30 radar features before the weights of the first model layer were analyzed to determine the importance of individual features to the converged model. Lastly, a sensitivity analysis was conducted where noise was added to individual input features and the changes in the output were monitored to determine the sensitivity of the model to input noise. As a result, the maximum, median, and variance of the amplitude and Doppler values were chosen to be extracted during the radar data projection. In addition, the first and last three cells of the radar cube are cut off to avoid DFFT artifacts in the AE projection. Besides that, the image data is rescaled to an input height of 512 pixels using bilinear interpolation to lower the demand on computational resources."

In addition, multi-scale feature maps are extracted from intermediate backbone layers (to detect objects at different scales) and skip connections are used to directly pass the input data to the neck models [69  ###reference_b69###].

This method projects reference points onto camera images to query features from the surrounding pixels. Therefore, this method allows to attend to a fixed number of keys in an image (or feature map), regardless of their spatial size. While this projection was originally designed for a pinhole camera model, we introduce a spherical reference point projection to utilize it for low-level radar data.\nOur resulting fusion module consists of five distinct steps. First, the reference points are initialized as a set of 400 evenly distributed 3D points in a polar space with feature values sampled from a uniform distribution and cover the entire field of view (FoV) of the sensor. Next, the reference points are fed to a self-attention layer to allow the exchange of information between queries, which becomes important during the iterative refinement. After that, the reference points are projected onto the camera and the dual radar perspectives in the third step. Based on these projections, deformable cross-attention is used to query features from the (positional encoded) multi-level feature maps. In the last step, the queried features are passed through a feed-forward network (FFN) before they are combined in a max pooling layer. Besides that, each of the attention and FFN layers includes dropout, addition, and normalization layers.

Our proposed camera-radar fusion model outperforms both the radar-only RTNH [16  ###reference_b16###] baseline model as well as the recently proposed EchoFusion [3  ###reference_b3###] camera-radar fusion. In comparison to state-of-the-art lidar or camera-lidar fusion models, it shows a significantly lower performance in normal conditions but outperforms them in particularly difficult weather conditions like fog, sleet, or heavy snow. This is most likely due to the radar\u2019s lower spatial resolution but higher robustness against environmental influences.\nThe comparison of different sensor modalities, as shown in Table II  ###reference_###, provides evidence for the effectiveness of our sensor fusion approach. It can be shown that the detection quality of the sensor fusion method exceeds even the combined performance of the individual sensor modalities, thus highlighting the effective use of the complementary sensor features. While the camera-only (C) configuration is similar to DETR3D [72  ###reference_b72###] it struggles with the multitude of severe weather scenarios, the small backbone size, and the inability to utilize multi-view camera images. The results for the fusion of camera data with radar data from the range-azimuth (RA) plane in comparison to the fusion with data from the azimuth-elevation (AE) plane demonstrate the importance of the different perception planes for 3D object detection. However, the results with both radar perspectives, in comparison to only one perspective, suggest that the correspondence of the radar data and the camera data in the image plane, in combination with the physical relationship between the two radar perspectives, supports the fusion of the two sensor modalities. This shows the importance of the complementary information from the RA perception plane on one side and the benefits of the additional AE plane for the association between camera and radar on the other."

The robustness against severe weather conditions can be seen in Figure 3  ###reference_### and shown by comparing the model performance under normal (norm.) conditions with the performance under different weather conditions of the K-Radar [16  ###reference_b16###] dataset. As shown in Table I  ###reference_###, the highest performance decrease for the DPFT model can be observed for the sleet condition, where a decrease of  can be measured in comparison to the normal condition. In comparison to that, the performance of the MixedFusion [55  ###reference_b55###] model decreased by  and the performance of EchoFusion [3  ###reference_b3###] decreased by .

Ultimately, it can be shown that our proposed DPFT model shows high robustness against server weather conditions and is equally robust as the radar-only RTNH [16  ###reference_b16###] method. However, the unimodal RTNH [16  ###reference_b16###] model performance is significantly lower and it cannot deal with a sensor modality failure.\n###figure_3### ###figure_4### ###figure_5### ###figure_6### The robustness of our method against sensor failure is achieved by a model design without interdependencies between the different modalities. While this prevents a complete failure of the model if a single sensor modality fails during runtime, the model performance still drops significantly, as shown in Table III  ###reference_###. To counteract this, we used the pre-trained weights of the camera and radar-only models as initialization [84  ###reference_b84###], but could not observe any significant changes. Besides that, we trained the model with modality dropout [85  ###reference_b85###] and were able to improve the performance for the sensor failure cases, but observed a significant decrease under nominal conditions, which is in contrast to [85  ###reference_b85###, 86  ###reference_b86###]."

Firstly, it outperforms lidar and camera-lidar fusion methods only in severe weather conditions while showing a significantly lower performance in normal conditions. Secondly, the model has difficulties detecting objects that are moving tangential to the ego vehicle\u2019s direction of travel and correctly predicting their heading angle, as shown in Figure 5  ###reference_###. This is probably caused by the fact that crossing objects are heavily underrepresented in the dataset on the one side and the inability of the radar sensor to measure tangential velocities on the other. Furthermore, it struggles to detect or differentiate between multiple objects that are behind each other or close to each other, which can be seen in Figure 5  ###reference_###. We believe that this is due to the partial occlusion and the limited resolution of the radar sensor in the azimuth-elevation plane. Last but not least, the generalization capability of the model could only be tested within the scope of the K-Radar [16  ###reference_b16###] dataset. Since the K-Radar [16  ###reference_b16###] dataset is the only dataset that provides raw 4D radar data for different weather conditions and the only large-scale dataset with radar cube data in general, the transferability of the model to different datasets is yet to be shown. Nevertheless, comparable model architectures [3  ###reference_b3###] that only rely on 3D radar data show promising generalization results, which is a first indicator for the transferability of these model types.\nDespite being the only dataset with 4D radar cube data, the K-Radar [16  ###reference_b16###] dataset shows some labeling inconsistencies (especially between the sedan and bus or truck classes) even within the revision v2.0. In addition, the test set is sampled from the same driving sequences and contains similar scenarios to the train set, which limits the ability to test the generalizability of models, even if the test split is formally independent. Furthermore, we observed a misalignment between the camera and lidar frame, as shown in Figure 5  ###reference_###, which is important because the labels are created on the lidar data, and which is why EchoFusion [3  ###reference_b3###] used their own calibration. However, a recalibration of the sensors is difficult and would limit the comparability to previous methods, which is why we used the official calibration. Nevertheless, further investigations would be needed to quantify the model\u2019s sensitivity to miscalibrations. Last but not least, the calculation of the total mAP metric in the official evaluation scheme could be misleading since it is calculated as the weighted average of the individual categories weighted by the number of ground truth objects. In general, the usage of the KITTI [79  ###reference_b79###] evaluation protocol could be questioned due to the problem of average precision distortion [88  ###reference_b88###] and since recent studies show that other metrics, like the nuScenes detection score (NDS), correlate better with the fulfillment of the autonomous driving task [89  ###reference_b89###]."

We are the first to fuse raw 4D radar data with camera data and demonstrate the importance of the different input perspectives. Our proposed DPFT method achieves state-of-the-art results in the challenging environmental conditions of the K-Radar dataset. Experimental results show that our proposed method is robust against severe weather conditions and is able to maintain general functionality even after a sensor failure. Finally, we provided a comprehensive analysis of the computational complexity of our method and were able to show that our method has the fastest inference time among all tested fusion methods.\nDespite the great potential of camera and radar fusion for 3D object detection, new research questions emerge from this work. While we proposed a novel dual perspective fusion approach, the general question of how to utilize the high dimensional radar data most efficiently remains open for research. Moreover, balancing the performance of different sensor modalities within a fusion method to exploit the input data most effectively and avoid significant performance losses during the event of a sensor failure remains challenging. Even if we used different methods to counteract the performance degradation after a sensor failure, further research is needed to mitigate this effect. Moreover, sensor-specific challenges like target separation in the radar domain or depth estimation in the camera domain remain open for research. Beyond that, temporal information could be considered to increase the performance and a different detection head could be used to realize an instance-free detection method in future work."

Following Section IV  ###reference_###, the results of Table A1  ###reference_### were obtained on the original version (revision v1.0) of the dataset, while all other additional results are based on the revised version (revision v2.0) of the dataset.\nThe results of Table A1  ###reference_### show decreasing mAP values with increasing IoU thresholds for all tested methods and both the 3D and the BEV object detection tasks. It is worth mentioning that the results of the DPFT method, listed in Table A1  ###reference_###, are the mean values of three independent model trainings to mitigate the effects of any non-deterministic training behavior. It can be seen that our proposed method outperforms all previous radar- and camera-radar-based methods for 3D object detection at all IoU thresholds and performs on par with the RTNH [16  ###reference_b16###] method for BEV detections at a low IoU threshold. However, our proposed method archives higher mAP values for BEV detection at higher IoU thresholds.\nThe experimental results of Table A2  ###reference_### show the performance of our DPFT model for different sensor modalities and detection range bins. It can be seen that the general performance of the model decreases with increasing range. This is especially true for the camera-only model, which shows a significant performance decrease with increasing detection range. The observed behavior is probably caused by the inability of the camera sensor to measure depth information and its decreasing spatial resolution with increasing distance. In contrast, the radar-only model shows a lower performance for the range between 0 -  and achieves the highest performance in a range between 10 - , with a decreasing performance over increasing distance. This phenomenon is probably caused by the higher noise level of the radar in close range and the decreasing spatial resolution with increasing distance. The performance of the camera-radar fusion model shows a similar behavior to the radar-based model, but a higher performance overall and seems to be less affected by increasing distance. We believe that this is a result of the already discussed sensor properties and the distribution of objects in the dataset that contains the most objects in a range of 20 -  and the least for distances greater than  [16  ###reference_b16###]."

The results of Table A3  ###reference_### show that all configurations of the DPFT model perform better under daytime conditions than nighttime conditions. Nevertheless, the performance of the camera-only model is affected the most, while the radar-only model shows the smallest decrease of all tested configurations. This is probably because camera sensors are dependent on ambient light, while radar sensors are active sensors and, therefore, independent from external sources. However, the general tendency could also be explained by the data distribution of the K-Radar dataset, which consists of  daytime scenes, which results in an imbalanced training and test set [16  ###reference_b16###].\nThe analysis of individual models shows that the camera-based model fails if the camera lens is covered by raindrops or sleet (as shown in A1  ###reference_###), which only gets worse in night-time conditions. However, these problems cloud be avoided by a different camera positioning or cleaning mechanism. The radar-based performance seems to be less affected by environmental conditions but more dependent on the number of available training samples.

In the \\raisebox{-.8pt}{3}\u20dd step, Feature Pyramid Networks (FPN) are used to align the dimensions of the multi-level feature maps. To fuse the features of the different perspectives, a set of query points is initialized in 3D space in the \\raisebox{-.8pt}{4}\u20dd step and projected onto the different perspectives in the \\raisebox{-.8pt}{5}\u20dd step.

+    "abstract": "Click-Through Rate (CTR) prediction holds a paramount position in recommender systems. The prevailing ID-based paradigm underperforms in cold-start scenarios due to the skewed distribution of feature frequency. Additionally, the utilization of a single modality fails to exploit the knowledge contained within textual features.\nRecent efforts have sought to mitigate these challenges by integrating Pre-trained Language Models (PLMs). They design hard prompts to structure raw features into text for each interaction and then apply PLMs for text processing. With external knowledge and reasoning capabilities, PLMs extract valuable information even in cases of sparse interactions. Nevertheless, compared to ID-based models, pure text modeling degrades the efficacy of collaborative filtering, as well as feature scalability and efficiency during both training and inference.\nTo address these issues, we propose Cost-Efficient Language Model Alignment (CELA) for CTR prediction. CELA incorporates item textual features and language models while preserving the collaborative filtering capabilities of ID-based models. This model-agnostic framework can be equipped with plug-and-play textual features, with item-level alignment enhancing the utilization of external information while maintaining training and inference efficiency. Through extensive offline experiments, CELA demonstrates superior performance compared to state-of-the-art methods. Furthermore, an online A/B test conducted on an industrial advertising recommender system showcases its practical effectiveness, solidifying the potential for real-world applications of CELA.

+            "text": "Recommender systems deliver personalized items to users by analyzing user browsing history and demographics, presenting users with items tailored to their preferences. Click-through Rate (CTR) prediction plays a crucial role in this process by estimating the likelihood that the user will interact with a specific item. This ensures that the displayed items are those most likely to bolster user engagement and revenue.\n###figure_1### The ID-based paradigm has garnered considerable success. Notable examples include DeepFM (Guo et al., 2017  ###reference_b13###), PNN (Qu et al., 2016  ###reference_b28###), and DCN (Wang et al., 2017  ###reference_b34###), which focus on high-order explicit feature crossing, while DIN (Zhou et al., 2018  ###reference_b42###) and DIEN (Zhou et al., 2019  ###reference_b41###) are geared towards mining behavior sequences. This paradigm, illustrated on the left side of Figure 1  ###reference_###, entails encoding user and item features into sparse one-hot vectors, subsequently transforming into dense embedding vectors via a lookup process. Latent co-occurrences among features are discerned via a feature interaction layer. Over the past decade, the advancement of these models has centered on developing more sophisticated and scenario-adapted feature interaction layers as a means to enhance overall performance.\nDespite their prevalence, ID-based models exhibit certain limitations:\n1) Dependence on historical data: This dependence can result in suboptimal modeling in scenarios such as cold-start or long-tail elements, where historical interactions for items or features are limited or absent, leading to inadequate learning of embeddings.\n2) Limited feature scope: Primarily focusing on categorical and numerical features, ID-based models overlook other modalities like text, which may harbor untapped knowledge that could potentially enhance the model\u2019s effectiveness.\nTo alleviate these limitations, works such as PTab (Liu et al., 2022  ###reference_b24###) and CTRL (Li et al., 2023  ###reference_b19###)\nhave integrated Pre-trained Language Models (PLMs) into recommender systems. These models employ hard prompts to structure raw features for each interaction, subsequently processed through PLMs for recommendation purposes, as shown on the right side of Figure 1  ###reference_###. By adopting natural language to represent features instead of one-hot vectors, this approach preserves the semantic integrity of features. This enables PLMs to apply their external knowledge and reasoning capabilities, effectively capturing valuable information even in cases of sparse interactions. For example, ID-based models struggle to learn embeddings for infrequently interacted items like bread, whereas PLMs utilize external knowledge to classify rice as a type of food, akin to toast. Concurrently, this natural language representation facilitates the integration of textual features, such as item descriptions, thereby augmenting the recommender system\u2019s effectiveness.\nHowever, these text-enhanced models face inherent limitations that hinder their practical deployment, shown in Figure 1  ###reference_###.\nFirst, modeling based exclusively on pure text may not be ideally suited for capturing collaborative signals, which often results in reduced performance (Li et al., 2023  ###reference_b19###).\nSecond, scalability issues emerge as the number of features increases, potentially leading to constructed text exceeding the language model\u2019s maximum token limit and thus losing valuable information, particularly when the sequence of user behaviors is extensively long. Furthermore, it becomes impractical to delineate user behaviors in a detailed manner, including the specification of item features for each behavior (Yang et al., 2024  ###reference_b38###).\nLast but not least, to bridge the gap between PLM outputs and recommendation tasks, PLMs are usually fine-tuned at the interaction-level (Liu et al., 2022  ###reference_b24###; Geng et al., 2022  ###reference_b11###; Li et al., 2023  ###reference_b19###; Muhamed et al., 2021  ###reference_b27###), yet this process is notably time-intensive. Such inefficiency inherent in PLM text processing extends to inference as well (Liu et al., 2022  ###reference_b24###; Geng et al., 2022  ###reference_b11###; Lin et al., 2024  ###reference_b23###; Bao et al., 2023  ###reference_b2###).\nTo overcome these challenges, we propose the Cost-Efficient Language Model Alignment (CELA) for CTR prediction.\nTo mitigate cold-start issues, CELA expands its feature scope by leveraging item text features and PLMs to generate more accurate item and user profiles. To maintain optimality and reduce inference latency, CELA integrates ID-based models, sustaining the efficacy and efficiency of collaborative filtering. For scalability, CELA shifts from the hard prompt mode to using PLMs solely as encoders for item textual features. Furthermore, to reduce training costs, CELA fine-tunes PLMs through item-level alignment.\nCELA is structured as a three-phase paradigm:\n1) Domain-Adaptive Pre-training stage, the PLM is further pre-trained on a corpus of item textual features, tailoring it to the specific dataset;\n2) Recommendation-Oriented Modal Alignment stage, contrastive learning is employed to align the PLM with the item ID embedding table of a developed ID-based model. This alignment is at the item level, ensuring minimal training overhead;\nand 3) Multi-Modal Feature Fusion stage, aligned text representations of each item are cached, facilitating efficient access via item identifiers, thereby reducing inference costs. Then these text representations are integrated into a new ID-based model, along with non-textual features, enabling their interplay to identify potential click patterns.\nThe final two stages are structured for alternate execution, ensuring ongoing alignment of the PLM with the progressively refined embedding table.\nThe main contributions of this paper are summarized as follows:\nWe propose a novel paradigm for integrating item textual features with ID-based models. This approach is model-agnostic and necessitates minimal modifications to the existing network architecture, rendering it conveniently applicable.\nWe develop an item-level alignment strategy to direct the capabilities of the PLM for recommendation tasks, thereby reducing training time overhead and achieving performance enhancements. Moreover, the cached item text representations are indexed by item identifiers during inference, ensuring low latency.\nComprehensive offline experiments on public and industrial datasets demonstrate the effectiveness of CELA. An online A/B test within an industrial advertising recommender system further validates CELA\u2019s real-world efficacy and feasibility."

Leveraging this corpus for further pre-training, we utilize the Masked Language Model Loss (MLM) (Devlin et al., 2019  ###reference_b7###), which masks a portion of tokens within a sentence and calculates the loss for each masked token prediction. For instance, the input text \u201dThis ballet skirt is nice for dress-up play for ballerinas\u2026,\u201d may be masked as \u201dThis ballet skirt is [MASK] for dress-up play for [MASK]\u2026\u201d, forcing the PLM to predict the mask tokens and give the MLM loss as:\nwhere  denotes the item space,  denotes item \u2019s textual feature,  and  denote the masked tokens and the rest of the tokens, respectively.\nSimultaneously, to enhance item text representations and mitigate the anisotropy issue (Ethayarajh, 2019  ###reference_b9###; Li et al., 2020  ###reference_b18###)\u2014where learned representations are constrained to a narrow cone in vector space, reducing expressiveness\u2014we incorporate SimCSE (Gao et al., 2021  ###reference_b10###) into our framework.\nSimCSE, an unsupervised technique, employs contrastive learning, treating a text as its positive pair by feeding it into the PLM twice with standard dropout as the only noise. By drawing positive pairs closer, the PLM is compelled to discern the meanings of texts amidst noise, thereby improving its comprehensive capacity. Moreover, distancing the representations of distinct texts promotes a more uniform distribution of representations in vector space, addressing the anisotropy and yielding superior text representations.\nThis process can be formulated as:\nwhere  denotes the similarity function,  denotes the temperature scaling the similarity measure, and  and  denote the representations of item \u2019s text.\nThe composite loss function for the PLM\u2019s pre-training is:\nwhere  is a weighting parameter that balances the contributions of the MLM loss and SimCSE loss.

We observe that:\nPLMs enhance ID-based models as item textual feature encoders. UniSRec and CELA surpass ID-based models on MovieLens and AppGallery. This demonstrates that PLMs capture valuable information from item textual features not exploited by collaborative filtering, thereby improving model efficacy.\nPurely text-based models typically underperform ID-based models. This is evidenced by the performance of P5, and PTab, which are inferior to most ID-based models. These findings are consistent with the results reported by (Li et al., 2023  ###reference_b19###), which underscore the limitations of exclusive reliance on semantic modeling.\nThe integration of semantic and collaborative signals leads to improved performance. This is demonstrated by CTRL, UniSrec, and CELA, which excel in most cases. The injection of semantics into the ID-based model distinguishes them from traditional ID-based models. Furthermore, the retention of collaborative signals makes them outperform other text-enhanced models.\nTask-oriented alignment is crucial for PLMs to eliminate the representation discrepancy and better adapt to downstream tasks. By aligning the outputs of PLMs and ID-based models, CTRL and CELA outperform UniSRec across three datasets. This outcome indicates that a simple whitening process in UniSRec is insufficient to bridge the gap. Therefore, alignment is essential to tailor PLMs for recommendation purposes.\nUsing PLMs solely as item textual feature encoders prevents information loss from feature proliferation. Compared to CTRL, CELA performs better in all cases since it extracts textual information from behavior sequences by encoding each item\u2019s textual feature individually, thus avoiding lengthy annotations resulting from including all features of an item. In contrast, CTRL transforms tabular data into textual data using a hard prompt template and takes the PLM as a textual data encoder, which fails to provide detailed annotations for items in user behaviors due to token number limitations, leading to information loss."

Results presented in Table 2  ###reference_### reveals that:\nModels utilizing hard prompt templates are impractical for real-world applications due to high training costs or inference overhead. This is attributable to their model complexity, indicated by the number of parameters. Training models like P5, PTab, CTR-BERT, and CTRL on extensive interaction-level textual data requires significant time, leading to infrequent updates and the use of outdated models, which negatively impacts performance. Additionally, the high inference overhead of P5, PTab, and CTR-BERT renders them unsuitable for real-time serving.\nUniSRec and CELA maintain training and inference costs comparable to DIN. However, UniSRec\u2019s performance is limited due to the lack of fine-tuning of the PLM. This limitation arises from insufficient alignment of the PLM\u2019s knowledge with downstream tasks, resulting in suboptimal integration of textual and non-textual features. In contrast, CELA fine-tunes the PLM with negligible training expense, achieving superior performance.\nCELA is efficient in both training and inference, making it industry-friendly. Its low training expense results from fine-tuning the PLM at the item level rather than the interaction level, as the number of items is significantly lower than the number of interactions, with a difference of up to 550 times here. Moreover, CELA\u2019s inference cost is comparable to that of DIN as it avoids real-time text processing, utilizing an additional text embedding table that occupies only 87.2MB of storage space."

This validates that PLMs can effectively extract knowledge from item textual features, benefiting CTR prediction.\nAs the complexity of the comprehensive PLM increases, CELA\u2019s performance gains plateau. Notably, BERTLarge underperforms compared to RoBERTaBase due to its larger parameter set, which does not fine-tune effectively with limited items. This suggests that beyond a certain threshold, additional parameters do not yield proportional improvements, indicating that a medium-sized PLM is sufficient for optimal performance.\nGenerative decoder-based large language models do not enhance CELA as effectively as comprehensive PLMs. Specifically, CELA with OPT shows decreased performance compared to comprehensive PLMs. This reduction is due to the difficulty in fine-tuning large parameter models with limited data and the generative PLM\u2019s unsuitability as a text encoder for CTR prediction.\n###figure_4###"

+    "abstract": "Design features of social media platforms, such as infinite scroll, increase users\u2019 likelihood of experiencing normative dissociation \u2014 a mental state of absorption that diminishes self-awareness and disrupts memory. This paper investigates how adding design frictions into the interface of a social media platform reduce mindless scrolling and user satisfaction. We conducted a study with 30 participants and compared their memory recognition of posts in two scenarios: one where participants had to react to each post to access further content and another using an infinite scroll design. Participants who used the design frictions interface\nexhibited significantly better content recall, although a majority of participants found the interface frustrating. We discuss design recommendations and scenarios where adding design frictions to social media platforms can be beneficial.",

+            "section_name": "1. Introduction",
+            "text": "Social media platforms have a direct impact on users\u2019 well-being and mental health (Sadagheyani and Tatari, 2020  ###reference_b22###; Berryman et al., 2018  ###reference_b4###; Abi-Jaoude et al., 2020  ###reference_b2###). The use of these platforms can increase feelings of depression and loneliness (Sadagheyani and Tatari, 2020  ###reference_b22###), especially among young people (Berryman et al., 2018  ###reference_b4###; Abi-Jaoude et al., 2020  ###reference_b2###). Researchers have suggested that these adverse effects of social media are not coincidental, but rather strategically designed (Monge Roffarello et al., 2023  ###reference_b20###; Monge Roffarello and De Russis, 2022  ###reference_b18###; Bhargava and Velasquez, 2021  ###reference_b5###). Features of social media known as attention-capture dark patterns (Monge Roffarello et al., 2023  ###reference_b20###; Monge Roffarello and De Russis, 2022  ###reference_b18###) are purposely integrated to capture user attention and increase time spent online. One design\nfeature commonly found across platforms is infinite scroll (Monge Roffarello et al., 2023  ###reference_b20###), where \u201cusers trigger the dynamically loading of additional content by scrolling down the page\u201d (Rixen et al., 2023  ###reference_b21###). Despite its popularity and ease of use, infinite scroll is associated with mindless scrolling (Mildner and Savino, 2021  ###reference_b17###) as it keeps users engaged in prolonged sessions (Monge Roffarello et al., 2023  ###reference_b20###), often leading to subsequent feelings of regret (Rixen et al., 2023  ###reference_b21###). Baughan et al. (Baughan et al., 2022  ###reference_b3###) showed how the infinite feed of X can increase the propensity to experience normative dissociation \u2014an absorbed state of mind characterized by a loss of awareness (Butler, 2006  ###reference_b6###) and a disruption in memory (Freyd et al., 1998  ###reference_b8###), rendering users unable to remember what they read online. To mitigate the adverse effects of attention-capture dark patterns, researchers and designers have developed external supports to help users self-limit and self-monitor their social media use. These tools operate on top of social media apps without changing their inner workings and can include timers and locks that limit the access to platforms (Zhang et al., 2022  ###reference_b30###). However, external supports are not application-specific and indiscriminately block access to content that people might still want to engage with (Lukoff et al., 2023  ###reference_b12###; Tran et al., 2019  ###reference_b27###). An emerging and relatively unexplored approach involves redesigning the interfaces to eliminate internal mechanisms that are commonly perceived to negatively affect users\u2019 well-being (Zhang et al., 2022  ###reference_b30###). For instance, researchers have demonstrated that nudging users about content they have already seen helps them avoid scrolling through old posts and increases the session quality (Zhang et al., 2022  ###reference_b30###). Similarly, hiding distracting recommendations when using YouTube for educational purposes has shown positive effects on users\u2019 sense of agency (Lukoff et al., 2023  ###reference_b12###). Redesigning interfaces appears to be more effective in enhancing a sense of agency and well-being than external supports to self-limit and self-control social media usage (Zhang et al., 2022  ###reference_b30###).\nOur paper contributes to this line of work by exploring how adding design frictions (i.e., points of difficulty in users\u2019 experience with technology) affects user satisfaction and mindless scrolling on social media. We drew inspiration from the notion of microboundaries \u2014 small moments of friction that are designed to interrupt automatic, mindless interactions by providing opportunities for reflection (Cox et al., 2016  ###reference_b7###). We conducted a study to analyze how adding a microboundary to users\u2019 interactions with social media posts affects mindless scrolling. Specifically, we made reacting to posts a prerequisite for accessing further content (reaction-based interface) and compared it with an infinite-scroll version of the same application. Following the normative dissociation framework, we operationalize mindless scrolling as a state of \u201cabsorption and a diminished self-awareness, often accompanied by a reduced sense of time, control and a gap in one\u2019s memory.\u201d (Baughan et al., 2022  ###reference_b3###) Thus, we assessed mindless scrolling by measuring participants\u2019 recognition memory of posts while interacting with both interfaces. Then, we measured user satisfaction when using the reaction-based interface, given that feelings of frustration are common when frictions are added to users\u2019 primary tasks in social media (Wang et al., 2014  ###reference_b28###; Monge Roffarello and De Russis, 2023  ###reference_b19###). We found that participants who interacted with the reaction-based interface remembered the content of posts more often than those who used the interface featuring infinite scrolling. This suggests that our intervention can prevent users from experiencing a symptom of normative dissociation, namely, a disruption in the ability to recall information. However, more than half of the participants (53%) felt frustrated by having to react to each post, and only three out of 15 (20%) indicated that they would like to use platforms that include this feature. We discuss design implications, such as taking situational needs into account and giving users the option to switch back to an interface with infinite scroll to reduce feelings of frustration. We also discuss scenarios where making users react to content can be useful, such as educational apps that require a more present state of mind."

Despite its advantages, studies indicate that infinite scroll is not a neutral design pattern, but rather one of the main causes why people mindlessly scroll on social media (Mildner and Savino, 2021  ###reference_b17###). Infinite scroll promotes endless sessions by reducing people\u2019s mental and physical effort (Widdicks et al., 2020  ###reference_b29###; Monge Roffarello et al., 2023  ###reference_b20###). To prevent mindless scrolling, researchers have suggested incorporating custom lists into the interface of Twitter to nudge users when they exhausted new content (Baughan et al., 2022  ###reference_b3###). This intervention helped people feel more in control of their scrolling compared to when the content was shown all together in the defaulted infinite feed. Similarly, Monge and De Russis (Monge Roffarello and De Russis, 2023  ###reference_b19###) found that nudging users when scrolling too quickly increased participants\u2019 feelings of control over their social media use.\nInfinite feeds have also been associated with an increased likelihood of people experiencing normative dissociation symptoms (Baughan et al., 2022  ###reference_b3###). According to Butler (Butler, 2006  ###reference_b6###), states of normative dissociation are characterized by a high level of absorption where people experience low levels of self-awareness, reflective consciousness, and intention. One of the most common characteristics is a disruption in memory known as highway hypnosis. Freyd et al. (Freyd et al., 1998  ###reference_b8###) describe this experience as the loss of awareness while performing an activity, such as driving a car, and then switching back to a conscious state of mind without a clear memory of what happened. However, it is important to note that these experiences are natural and common cognitive processes that people engage with when performing activities like reading a book, exercising, or walking (Butler, 2006  ###reference_b6###). States of flow (Snyder and Lopez, 2001  ###reference_b23###), for example, where there is a dynamic interplay between challenges and skills as people engage in meaningful activities, are highly rewarding and tend to encourage repetition. Normative dissociation experiences on social media become problematic when it reduces the volition and sense of control of the users, making them feel that their objectives regarding social media use have not been met (Baughan et al., 2022  ###reference_b3###). Studying mindless scrolling through the normative dissociation framework does not only provide us a quantitative assessment method, but also a better understanding that takes into account the expectations, intentions, and goals of the users.\nTo avoid automatic and thoughtless behaviors while interacting with technology, researchers have begun advocating for the integration of design frictions into user interfaces (Cox et al., 2016  ###reference_b7###; Gould et al., 2021  ###reference_b9###; Mejtoft et al., 2023  ###reference_b16###, 2019  ###reference_b15###). Design frictions are defined as points of difficulty encountered during the interaction with technology (Cox et al., 2016  ###reference_b7###), typically to prevent mistakes (e.g., a pop-up message to confirm an action). In UX/UI design, the general belief is that the less friction a platform has, the more seamless, effortless, and painless the interactions will be, and therefore, frictions should be avoided at all costs. However, researchers have started to explore the benefits of purposely adding design frictions into peoples\u2019 interaction with technology to promote more mindful experiences (Cox et al., 2016  ###reference_b7###). Wang et al. (Wang et al., 2014  ###reference_b28###), for instance, showed adding time delays before posting increased self-reflection among Facebook users and helped them avoid heated online discussions. Similarly, Haliburton et al. (Haliburton et al., 2024  ###reference_b10###) showed that imposing customizable short delays when users opened a target app increased intentional use over time. Lyngs et al. demonstrated that goal reminders helped users to stay on task while using Facebook, although with the risk of the intervention becoming annoying (Lyngs et al., 2020  ###reference_b14###). Our study builds on this line of work by exploring the effect of adding small frictions to users\u2019 interaction with a social media feed to prevent mindless scrolling."

Since design frictions can be wide-ranging and encompass different types of interventions (Cox et al., 2016  ###reference_b7###), we opted to design a reaction-based interface of a social media application that makes reacting to posts a prerequisite to engage with further content and compared it with an infinite-scroll version of the same application. Therefore, we ask (1) How does the reaction-based interface affect mindless scrolling compared to the infinite-scroll interface? and (2) How does the reaction-based interface affect user experience? We operationalize mindless scrolling using the normative dissociation framework and measured the ability of the participants to recall content through an old-new memory recognition test (Zimmerman and Brown-Schmidt, 2020  ###reference_b31###). Additionally, we elicited participant impressions of the interface containing design frictions through a survey.\n###figure_1### This figure displays three mobile phone screens, each containing a header and a feed of posts. The first two screens belong to the reaction-base interface while the last one to the infinite-scroll interface The first screen illustrates a user pressing a \u201dlike\u201d button, which reveals four reaction options above it.

The only difference between the conditions was the mechanism users employed to interact with content; other elements of the feed, such as content, pictures, users, and the order of posts, remained unchanged. In the infinite-scroll version, the content was rendered dynamically as the person scrolled down the feed. In contrast, the reaction-based version required participants to react to the current post to view the next one. If participants did not wish to react to a post, they had the option to press a \u201cnot interested\u201d button to skip to the next one.\nBoth versions of the application contained the same image and text-based posts, similar to those on platforms like Facebook and Reddit. As the ability to recall content can be highly sensitive to the topic of the posts, we included 10 different categories: Art, Cooking, Learning, Sports, Personal development, Entrepreneurship, Technology, Yoga, Research, and Hobbies. We extracted and modified the post texts from subreddits of Reddit dedicated to those categories (e.g., r/painting and r/cooking). The subreddits for each category were selected based on their popularity, measured by the number of members. The criteria for selecting the posts were the quality and size of the text. Due to privacy reasons, we used images from free stock image websites. Moreover, each post included a reaction button. This button was modeled after the popular reactions available on Facebook. and displayed four different reactions for participants to select: \u201cLike\u201d, \u201cCongratulations!\u201d, \u201cInspiring!\u201d, and \u201cLove it!\u201d. These reactions were selected for their positive and encouraging tone, as the posts focused on people\u2019s progress in personal projects and hobbies. Offering four reaction options instead of a \u201dnext post\u201d button was intended to encourage participants to pause briefly and select the reaction that best aligned with their perception of the content."

Then, they completed a survey to elicit their social media behavior and previous experiences of normative dissociation on social media. Upon completion, participants underwent two phases of an old-new recognition test \u2014 an exposure phase and a test phase (Zimmerman and Brown-Schmidt, 2020  ###reference_b31###). The primary objective of the test was to draw conclusions about memory performance by calculating the memory sensitivity of each participant (d\u2019), which assessed their ability to accurately recognize stimuli they had previously encountered as \u201cold\u201d and distinguish them from those they had not seen before as \u201cnew\u201d (Toth et al., 2021  ###reference_b26###). During the exposure phase, participants used a smartphone with the app preinstalled. In the pilot study, 50 posts were perceived as overwhelming, so we decided to include 30 posts. We asked participants to browse the feed as they would in any social media app. They were not informed that their capacity to remember the content of the posts would be tested later. Then, participants performed the Stroop task to reduce memory performance, as retention of images tends to be high in the short term (Zimmerman and Brown-Schmidt, 2020  ###reference_b31###). In this task, participants were presented with color words written in mismatched colors (e.g., the word \u201cyellow\u201d written in red) and were asked to name the color of the word. Next, we tested their memory recognition ability by giving them a mobile phone with 30 posts, out of which 20 had been shown to them in the exposure phase, and 10 were new. Each post included two buttons: new and old. Participants had to select one to indicate whether they remembered seeing the post beforehand. At the end, the participants from the treatment group responded to a five-point Likert-scale questionnaire to collect their impressions of the reaction-based interface and their feelings of frustration, as one of the main challenges of designing frictions is determining the right amount of friction that does not interfere with a seamless user experience (see questionnaire in the appendix  ###reference_###). Participants in the intervention group took circa 20 minutes to complete the study, while those in the control group took 15 minutes."

Moreover, only half of the participants indicated that they remember most of the content they consume on social media. Twenty-one participants (70%) thought it was important to remember the content they engage with. This suggests that many participants acknowledged experiencing symptoms of normative dissociation while using social media, specifically a distortion in their perception of time, leading to long sessions and a decrease in the ability to recall content.\nA Mann-Whitney U test on the old-new recognition memory test scores indicated a significant difference in memory sensitivity (d\u2019) between the control and treatment groups (). Memory sensitivity (d\u2019) is widely used in old-new recognition tests and calculated using the z transforms of the hit rate H (correctly identified \u201dold\u201d stimuli) and the false alarm rate F (incorrectly identified \u201dnew\u201d stimuli) (Hautus et al., 2021  ###reference_b11###). Participants of the treatment group demonstrated a superior self-reported memory recognition (d\u2019) of the content they engaged with during the exposure phase (), compared to those who interacted with the infinite-scroll version (). A rank-biserial correlation indicated a large effect size of the intervention (). This suggests that requiring reactions to each post can be effective in preventing one symptom of normative dissociation \u2014 the self-reported reduced memory of the experience. Participants took significantly longer to interact with the reaction-based interface than with the infinite-scroll version (), which might help explain the difference in recall performance. On average, the intervention group took 8.67 (std = 2.690) minutes to scroll though all posts during the exposure phase, whereas the control group took only 3.33 (std = 1.589).\nFurthermore, the effect of the reaction-based interface was also perceived by the participants \u2014 67% either strongly agreed or agreed that this interface was effective in making them pay more attention to the content of the posts. However, more than half of the participants felt frustrated about having to react to each post (53%) and one in three (33%) indicated that they felt demotivated to continue using the app because of this feature. After concluding the experiment, a participant commented that the reason why he disliked the reactions is that he identified as a \u201clurker\u201d, and thus, prefers to remain unseen on social media platforms. Moreover, only 20% of the participants indicated that they would like to see more applications with this feature in the future. This shows a misalignment between the perceived usefulness of attentiveness while using social media and the willingness of the participants to engage with the proposed interface, which was mostly considered to be effective in increasing attention and memory of content."

+            "text": "Our findings align with the observations of Wang et al. (Wang et al., 2014  ###reference_b28###) regarding the inclusion of time delay before publishing social media posts \u2014 adding extra steps in interactions is regarded as both beneficial and annoying. Although we anticipated this effect and included a \u201dnot interested\u201d button for skipping posts without interacting, it was insufficient to prevent frustration. Based on our findings, we discuss recommendations for integrating frictions into users\u2019 interactions with social media feeds.\nFirst, to reduce the frustration likelihood while still leveraging the benefits of the reaction-based interface, we encourage designers and developers to create a less intrusive intervention that prompts users to react to posts at regular intervals (e.g., every 5-10 posts) instead of every time. This approach might be seen as less intrusive while still increasing attention. Moreover, the frequency in which users are required to react could also be left to individual preference. As Haliburton et al. (Haliburton et al., 2024  ###reference_b10###) showed, users benefit from customizing the duration of time delays while opening target apps based on personal requirements. Future work can explore the effect of varying the reaction frequency on user experience.\nSecond, there are scenarios where a reaction-based interface might still be beneficial, especially when a high level of involvement is desired. As highlighted by Lukoff et al. (Lukoff et al., 2021  ###reference_b13###), goal-oriented use that satisfies informational needs (e.g., searching for tutorials on YouTube) can be supported by more restrictive interfaces, which enhance users\u2019 sense of agency. Encouraging people to engage with posts on goal-oriented sessions could improve information recall and attention. Future research could investigate the impact of reaction-based interfaces on user experience on platforms such as LinkedIn, YouTube, or Medium, where informational and instrumental usage tends to be more prevalent.\nLastly, social media platforms could also benefit from incorporating a reaction-based interface to assist users in managing their social media use.\nFor instance, providing users the option to switch between a less permissive interface of YouTube without distracting recommendations and its standard version, depending on the intended use, results in increased satisfaction and alignment with goals (Lukoff et al., 2023  ###reference_b12###). Similarly, experiences of normative dissociation are generally perceived negatively when users feel they have wasted time and cannot recall what they read. However, becoming absorbed while browsing can also be considered a positive and beneficial experience by offering relief and escape from the present moment (Baughan et al., 2022  ###reference_b3###).Therefore, considering situational needs and contextual use is vital for the design of positive experiences online. We could offer a reaction-based interface for users who wish to regulate their social media use and avoid mindless scrolling, and an infinite scroll interface for when browsing in autopilot is not a concern.\nOur study has of course limitations. The generalizability of our findings is limited by a lack of gender diversity and the focus on a student sample. The ability to remember content on social media is not the only symptom of normative dissociation experiences. Future work could assess other symptoms such as loss of self-awareness and passage of time. Mindless scrolling is also influenced by users\u2019 interest and engagement with content, so the selected posts could have influenced these factors. Although we included posts of different categories, it was still small compared to the content available on social media. Future research should explore the impact of a reaction-based interface within"

+    "abstract": "Existing approaches to differentiable structure learning of directed acyclic graphs (DAGs) rely on strong identifiability assumptions in order to guarantee that global minimizers of the acyclicity-constrained optimization problem identifies the true DAG. Moreover, it has been observed empirically that the optimizer may exploit undesirable artifacts in the loss function. We explain and remedy these issues by studying the behaviour of differentiable acyclicity-constrained programs under general likelihoods with multiple global minimizers. By carefully regularizing the likelihood, it is possible to identify the sparsest model in the Markov equivalence class, even in the absence of an identifiable parametrization or even faithfulness. We first study the Gaussian case in detail, showing how proper regularization of the likelihood defines a score that identifies the sparsest model. These results are then generalized to general models and likelihoods, where the same claims hold. Furthermore, under standard faithfulness assumptions, our approach also recovers the Markov equivalence class. These theoretical results are validated empirically, showing how this can be done using standard gradient-based optimizers, thus paving the way for differentiable structure learning under general models and losses.",

+            "text": "Directed acyclic graphs (DAGs) are the most common graphical representation for causal models (Pearl, 2009  ###reference_b49###; Spirtes et al., 2000  ###reference_b61###; Peters et al., 2017  ###reference_b51###), where nodes represent variables and directed edges represent cause-effect relationships among variables.\nWe are interested in the problem of structure learning, i.e. learning DAGs from passively observed data, also known as causal discovery.\nOur focus will mainly be on score-based approaches to DAG learning (Chickering, 2003  ###reference_b12###; Heckerman et al., 1995  ###reference_b24###), where the structure learning problem is formulated as optimizing a given score or loss function  that measures how well the graph, represented as an adjacency matrix , fits the observed data , constrained to the graphical structure  being acyclic.\nThis combinatorial optimization problem is known to be NP-complete (Chickering, 1996  ###reference_b11###; Chickering et al., 2004  ###reference_b13###).\nRecent advances have introduced a continuous representation of DAGs, replacing the combinatorial acyclicity constraint with a continuous one through a differentiable function that exactly characterizes DAG structures (Zheng et al., 2018  ###reference_b74###, 2020  ###reference_b75###).\nIn this case, the discrete adjacency matrix  is first relaxed to the space of real matrices, i.e., , and then a differentiable function  is devised so that  if and only if  is a DAG (Zheng et al., 2018  ###reference_b74###; Bello et al., 2022  ###reference_b5###).\nThis results in the following optimization problem:\nConsidering a differentiable score function , the differentiable program (1  ###reference_###) facilitates the use of gradient-based optimization techniques along with the use of richer models, such as neural networks, for modeling the functional relationships among the variables\n (Zheng et al., 2020  ###reference_b75###; Yu et al., 2019  ###reference_b68###; Ng et al., 2020  ###reference_b42###; Lachapelle et al., 2020  ###reference_b30###; Pamfil et al., 2020  ###reference_b45###; Kyono et al., 2020  ###reference_b29###; Zhu et al., 2020  ###reference_b77###). One of the most attractive features of this approach is that it applies to general models, losses, and optimizers, in contrast to prior work. Moreover, it cleanly separates computational and statistical concerns, so that each can be studied in isolation, in the same spirit as the graphical lasso (Meinshausen and B\u00fchlmann, 2006  ###reference_b37###; Yuan and Lin, 2007  ###reference_b69###; Friedman et al., 2008  ###reference_b18###).\nLooking back at the inception of the continuous DAG learning framework by Zheng et al. (2018  ###reference_b74###, 2020  ###reference_b75###), however, most developments in this framework have focused on the design of alternative differentiable acyclicity functions  with better numerical/computational properties (Bello et al., 2022  ###reference_b5###; Lee et al., 2019  ###reference_b33###; Zhang et al., 2022  ###reference_b73###; Yu et al., 2019  ###reference_b68###), placing little emphasis on which score function to use (Ng et al., 2020  ###reference_b42###).\nIn fact, and unfortunately, regardless of the modeling assumptions, it has become a rather standard practice (Yu et al., 2019  ###reference_b68###; Zheng et al., 2020  ###reference_b75###; Bello et al., 2022  ###reference_b5###; Deng, Bello, Aragam and Ravikumar, 2023  ###reference_b14###; Lee et al., 2019  ###reference_b33###; Kyono et al., 2020  ###reference_b29###) to simply use the least squares (LS) loss (a.k.a. \u201creconstruction loss\u201d) as the score by default, following the original paper by Zheng et al. (2018  ###reference_b74###), despite its known statistical limitations (Van de Geer and B\u00fchlmann, 2013  ###reference_b64###; Loh and B\u00fchlmann, 2014  ###reference_b34###; Aragam et al., 2019  ###reference_b2###).\nAs a result,\nReisach et al. (2021  ###reference_b56###) flagged the empirical successes of continuous structure learning (CSL) methods as largely due to the high agreement between the order of marginal variances of the nodes and the topological order of the underlying simulated DAGs, a concept they describe as \u201cvarsortability\u201d.\nThen, Reisach et al. (2021  ###reference_b56###) empirically showed that the performance in structure recovery of CSL methods drops significantly after simple data standardization.\nMore recently, Ng et al. (2024  ###reference_b43###) demonstrated that this phenomenon may not be explained by varsortability, and instead pointed out that the explanations are due to the score function, albeit without proposing which score function to use. These observations motivate a deeper consideration of the choice of score.\nUnfortunately, despite the fact that several score functions have been proposed for learning Bayesian networks (such as BIC (Heckerman et al., 1995  ###reference_b24###), BDeu (Maxwell Chickering and Heckerman, 1997  ###reference_b36###), and MDL (Bouckaert, 1993  ###reference_b7###)), their application to CSL methods is not well understood.\nThis paper is precisely concerned with finding a suitable and general score function with strong statistical properties for CSL methods.\nThat is, our objective is to find a score function that is: (1) differentiable so that it is amenable to gradient-based optimization; (2) applicable to general models; (3) scale-invariant; (4) capable of identifying the sparsest model under proper regularization; and (5) connects nicely with classical concepts from Bayesian networks such as faithfulness and Markov equivalence classes.\nContributions. The main contribution of our work is to show that a properly regularized, likelihood-based score function has the five properties outlined above. We begin with Gaussian models to convey the main ideas, and then discuss generalizations.\nIn more detail:\n(Section 4  ###reference_###) Starting with Gaussian models,\nwe show that using the log-likelihood with a quasi-MCP penalty (10  ###reference_###) as the scoring function leads to optimal solutions of (1  ###reference_###) that correspond to the sparsest DAG structure which is Markov to  (Theorem 1  ###reference_orem1###).

Regarding nonlinear SEMs, significant contributions have been made in additive models (B\u00fchlmann et al., 2014  ###reference_b10###; Ernest et al., 2016  ###reference_b16###; Voorman et al., 2014  ###reference_b65###), additive noise models (Hoyer et al., 2008  ###reference_b25###; Peters and B\u00fchlmann, 2014  ###reference_b50###; Mooij et al., 2016  ###reference_b40###), generalized linear models (Park and Raskutti, 2017  ###reference_b48###; Park and Park, 2019b  ###reference_b47###; Gu et al., 2019  ###reference_b23###), and broader nonlinear SEMs (Monti et al., 2020  ###reference_b39###; Goudet et al., 2018  ###reference_b22###).\nWorks that are more directly connected to our research include those developed in the continuous structure learning (CSL) framework (e.g. Zheng et al., 2018  ###reference_b74###, 2020  ###reference_b75###; Deng, Bello, Aragam and Ravikumar, 2023  ###reference_b14###; Bello et al., 2022  ###reference_b5###; Deng, Bello, Ravikumar and Aragam, 2023  ###reference_b15###; Lachapelle et al., 2020  ###reference_b30###; Zhu et al., 2020  ###reference_b77###; Ng et al., 2020  ###reference_b42###; Moraffah et al., 2020  ###reference_b41###; Kyono et al., 2020  ###reference_b29###; Pamfil et al., 2020  ###reference_b45###).\nMost of these papers focus on empirical and computational aspects, and only a few study the theoretical properties of the CSL framework in (1  ###reference_###). These include: Wei et al. (2020  ###reference_b66###); Ng et al. (2022  ###reference_b44###) studied the optimization and convergence subtleties of problem (1  ###reference_###); Deng, Bello, Aragam and Ravikumar (2023  ###reference_b14###) studied optimality guarantees for more general types of score functions and proposed a bi-level optimization method to guarantee local minima; Deng, Bello, Ravikumar and Aragam (2023  ###reference_b15###) designed an optimization scheme that converges to the global minimum of the least squares score in the bivariate case.\nFinally, among the few works that study score functions under this framework, we note: Ng et al. (2020  ###reference_b42###) studied the properties of the -regularized profile log-likelihood, which leads to quasi-equivalent models to the ground-truth DAG; and the authors in Seng et al. (2023  ###reference_b57###) claim that a family of likelihood-based scores reduce to the least square loss, although this only holds under knowledge of the noise variances (Loh and B\u00fchlmann, 2014  ###reference_b34###). Perhaps most closely related to our work is Brouillard et al. (2020  ###reference_b9###), who proved a similar identifiability result under the likelihood score.\nHowever, they used an  regularizer along with the faithfulness assumption, which leads to an inherently non-differentiable optimization problem that is much simpler to analyze. On the other hand, they also consider interventional data, which we do not pursue in this work. Extending our results to include interventional data and interventional Markov equivalence is an important direction for future work.\nIn contrast to the aforementioned works, we also prove that the log-likelihood has desirable properties such as being scale invariant, and when regularized by nonconvex and differentiable approximations of the  function, it provably leads to useful solutions that are minimal models and Markov equivalent to the underlying structure, without assuming faithfulness."

This leads to the concepts of faithfulness and sparsest representations, which we briefly recall here; we refer the reader to Spirtes et al.

One approach which we will use is the notion of a sparsest (Markov) representation (SMR), introduced in Raskutti and Uhler (2018  ###reference_b55###). A sparsest representation of  is a Markovian DAG  that has strictly fewer edges than any other Markovian DAG , and such sparsest representation is unique up to Markov equivalence class.\nTheorem 2.4 in Raskutti and Uhler (2018  ###reference_b55###) shows that if  is faithful to , then  must be a sparsest representation of . This notion is closely related to the notion of minimality we adopt in Definition 2  ###reference_inition2### (cf. Lemma 4  ###reference_ma4### in the Appendix).

For positive integers , we will use  and  to denote the model parameters for  and , respectively.111Given that  describes all the parameters for the functions , we will also use  to denote  in (3  ###reference_###).\nThen we denote the distribution of  by .\nLet  denote one observation of .\nGiven  i.i.d. samples  where , the negative log-likelihood and expected negative log-likelihood can be written as:\nwhere the subscript  in  is used to indicate the sample version of the log-likelihood.\nIdentifiability.\nLet  (resp. ) denote the model parameters for the ground truth  (resp. ), let  denote the induced weighted adjacency matrix, and let  denote the induced binary adjacency matrix.

For our variation of NOTEARS that employs a score function based on the NLL with MCP, we name it as logll-notears. The suffixes \u2018population\u2019 and \u2018sample\u2019 denote the use of the population and sample covariance matrix, respectively. Full details of the experiments are given in Appendix D  ###reference_###.\nOur primary empirical results are shown in Figures 2  ###reference_### and 3  ###reference_###. We use the structural Hamming distance (SHD) as the main metric to evaluate the difference between the estimated graph and the ground truth graph. Lower SHD values indicate better estimation accuracy. Given that the model specified in (6  ###reference_###) is nonidentifiable, we compare the CPDAGs of the estimated graph and the ground truth graph.\nIn Figure 2  ###reference_###(a), we observe that using the NLL+MCP achieves the best performance for the different types of graphs and ranks second best for sparse graphs {ER1, SF1}.\nIn Figure 2  ###reference_###(b), standardizing  significantly impacts the performance of GOLEM, NOTEARS, and DAGMA; the SHD values are not any better than an empty graph, exactly as predicted by prior theory. The performance of logll-notears-sample and logll-notears-population are also affected by standardization, but these methods remain robust and continue to make meaningful discoveries. It is important to note that this observation does not contradict our Lemma 2  ###reference_ma2###. The challenges arise because solving the optimization problems (12  ###reference_###) and (14  ###reference_###) to find global solutions becomes inherently difficult as  increases. To verify the scale invariance property in Theorem 3  ###reference_orem3###, we also conduct experiments on small graphs (8 nodes, ER-2 graph) and include exact method that solve (12  ###reference_###) and (14  ###reference_###) to global optimal, see Figure 6  ###reference_###.\nIn Figure 3  ###reference_###, we replicate the Figure 1 in Reisach et al. (2021  ###reference_b56###), providing a more direct comparison between various methods applied to raw data () and standardized data ( standardized). We include VarSort (referred to as sortnregress in Reisach et al. (2021  ###reference_b56###)) as a baseline. Notably, for smaller graphs (), both logll(-notears)-sample and logll(-notears)-population exhibit the scale-invariant property alongside PC and FGES, in alignment with Lemma 2  ###reference_ma2###. This contrasts sharply with other methods, which completely deteriorate. For larger graphs (), standardizing the data mildly degrades the performance of logll(-notears)-sample and logll(-notears)-population. This can be attributed to the increased complexity of optimization as the size of the graph grows.\nIn Figure 4  ###reference_###,\nwe use a concrete toy example to investigate two key factors in the implementation: (1) the impact of random initialization, and (2) the upper limit for  that can be applied according to Theorem 1  ###reference_orem1###.\nThe toy example in this case is the three-node fork graph .\nWe generate  initializations  with weight for each edges uniformly sampled within , and perform optimization using logll-notears starting from these points.\nThe \u201cmaximal \" is the theoretical maximum  that ensures the validity of Theorem 1  ###reference_orem1###. We computed the SHD and the distances between the estimated  and . The red line in Figure 4  ###reference_### represents the average SHD and distances. The distribution of these  estimated SHD and distances is visualized using dots of varying sizes, where larger dots indicate a higher frequency of points. In some cases where SHD takes a value of , this value is used to indicate that the estimated  does not form a valid DAG, which is an artifact of thresholding and affects  of models. For the remaining models, the optimization (12  ###reference_###) can typically be solved very close to a globally optimal solution, and according to Theorem 2  ###reference_orem2###, the SHD should ideally be zero, which is consistent with the figure.\nOur results are not limited to the linear model with Gaussian noise. In Appendix E.3  ###reference_###, we provide additional experiments on a logistic model (binary ) and neural networks. Further details on the experimental settings and additional experiments can be found in Appendix D  ###reference_### and E  ###reference_###.\n###figure_2### ###figure_3### ###figure_4### ###figure_5### ###figure_6###"

It has attracted significant attention due to its simplicity and generality, however, its theoretical properties are often misunderstood. We have sought to fill in this gap by studying its statistical aspects (to complement ongoing computational studies, e.g. Ng et al. (2020  ###reference_b42###); Wei et al. (2020  ###reference_b66###); Bello et al. (2022  ###reference_b5###); Deng, Bello, Aragam and Ravikumar (2023  ###reference_b14###); Deng, Bello, Ravikumar and Aragam (2023  ###reference_b15###); Ng et al. (2022  ###reference_b44###)).\nTo this end, we proposed a fully differentiable score function for structure learning, composed of log-likelihood and quasi-MCP. We demonstrated that the global solution corresponds to the sparsest DAG structure that is Markov to the data distribution. Under mild assumptions, we conclude that all optimal solutions are the sparsest within the same Markov equivalence class. Additionally, the proposed score is scale-invariant, producing the same structure regardless of the data scale under the linear Gaussian model. Experimental results validate our theory, showing that our score provides better and more robust structure recovery compared to other scores.\nWe hope that this work stimulates further statistical inquiry into the properties of CSL. For example, we have focused on parametric models, and left extensions to nonparametric models to future work.\nCertain assumptions such as the finiteness of the equivalence class and the boundedness of the level set of the log-likelihood become more interesting in this regime.\nWe have mentioned already that extensions to richer data types including interventions is an important direction.\nIt would be of great interest to explore ways to relax our assumptions to expand our statistical understanding of CSL in broader scenarios."

+    "title": "MICAS: Multi-grained In-Context Adaptive Sampling for 3D Point Cloud Processing",
+    "abstract": "Point cloud processing (PCP) encompasses tasks like reconstruction, denoising, registration, and segmentation, each often requiring specialized models to address unique task characteristics. While in-context learning (ICL) has shown promise across tasks by using a single model with task-specific demonstration prompts, its application to PCP reveals significant limitations. We identify inter-task and intra-task sensitivity issues in current ICL methods for PCP, which we attribute to inflexible sampling strategies lacking context adaptation at the point and prompt levels. To address these challenges, we propose MICAS, an advanced ICL framework featuring a multi-grained adaptive sampling mechanism tailored for PCP. MICAS introduces two core components: task-adaptive point sampling, which leverages inter-task cues for point-level sampling, and query-specific prompt sampling, which selects optimal prompts per query to mitigate intra-task sensitivity. To our knowledge, this is the first approach to introduce adaptive sampling tailored to the unique requirements of point clouds within an ICL framework. Extensive experiments show that MICAS not only efficiently handles various PCP tasks but also significantly outperforms existing methods. Notably, it achieves a remarkable  improvement in the part segmentation task and delivers consistent gains across various PCP applications.",

Specifically, these studies have not fully addressed critical challenges associated with conventional point cloud sampling techniques used in the ICL framework. Taking Figure 1  ###reference_### (a) for example, the ICL framework manages multiple point cloud tasks,\neach with distinct preferences for point cloud sampling.\nHowever, conventional sampling methods struggle to adapt equally well to these diverse tasks simultaneously.\nThese gaps, particularly in adapting sampling techniques to task-specific and prompt-specific contexts, hinder overall performance and reliability.\nTo overcome these limitations, our work tackles two critical issues:\n1) Inter-task Sensitivity: As illustrated in Figure 1  ###reference_### (b), task-agnostic sampling strategies, e.g., Farthest Point Sampling (FPS), may perform differently across different tasks, such as reconstruction and denoising.\nThis difference arises because FPS tends to prioritize outliers, often leading to the selection of noisy points.\nThis issue underscores the urgent need for a methodology that effectively integrates task information into the sampling process. 2) Intra-task Sensitivity: Depicted in Figure 1  ###reference_### (c), variations in prompts for the same task can yield divergent sampling outcomes, resulting in inconsistent experimental results.\nThis highlights the need to replace generic prompts with carefully curated, query-specific prompts.\nTo effectively address the inter-task and intra-task sensitivity issues, we introduce a novel Multi-grained In-Context Adaptive Sampling mechanism, dubbed MICAS, for 3D point cloud in-context learning. As shown in Figure 2  ###reference_### (b), MICAS comprises two integral components: task-adaptive point sampling and query-specific prompt sampling.\nFor inter-task sensitivity, task-adaptive point sampling enables adaptive sampling by interpreting various prompts, operating in two stages: prompt understanding and Gumbel sampling.\nFirst, the prompt understanding phase extracts essential task features from the prompt and corresponding point features from point clouds, providing a basis for informed sampling.\nHowever, traditional discrete sampling methods fail to support gradient-based optimization, jeopardizing both the efficiency and effectiveness of the learning process.\nTo address this, the Gumbel sampling phase leverages the Gumbel-softmax [19  ###reference_b19###], transforming discrete sampling into a differentiable operation and enabling a fully learnable and efficient sampling process [58  ###reference_b58###].\nTo mitigate the intra-task sensitivity caused by prompt variability, we integrate a query-specific prompt sampling module.\nThis module selects the most effective prompt by ranking the sampling probabilities, which are aligned to the inference performance.\nSpecifically, we first predict sampling probabilities for each prompt by analyzing\nqueries and prompts, followed by aligning these probabilities with the in-context learning model\u2019s performance. During inference, the \u201cbest-performing\u201d prompt is selected based on these probabilities among strategically chosen candidate prompts.\nWe evaluate our design on a benchmark [11  ###reference_b11###] comprising multiple existing datasets [5  ###reference_b5###, 66  ###reference_b66###], covering four distinct point cloud tasks with five levels of difficulty each.\nOur comprehensive evaluation demonstrates the efficacy of MICAS in addressing both inter-task and intra-task sensitivity issues.\nIn addition, these results highlight the practical advantages of MICAS, including enhanced adaptability to diverse 3D point cloud tasks and improved robustness across various ICL model variants.\nThe contributions of this paper are summarized as follows:\nWe propose a novel multi-grained in-context adaptive sampling mechanism, MICAS, that effectively addresses inter-task and intra-task sensitivity issues in 3D point cloud in-context learning.\nMICAS integrates two key components: task-adaptive point sampling and query-specific prompt sampling. The former dynamically adjusts to task-specific needs at the point level, while the latter refines prompt selection to minimize intra-task variability. Together, these components enable adaptive and efficient sampling across diverse 3D point cloud tasks.\nExtensive experiments demonstrate that MICAS not only simplifies training and efficiently handles multiple tasks but also achieves substantial performance gains over previous state-of-the-art methods, including a notable  increase in the part segmentation task."

Each pair consists of an input point cloud and its corresponding output point cloud for the given task [62  ###reference_b62###, 11  ###reference_b11###].

We replace the farthest point sampling (FPS) used in PIC-Cat [11  ###reference_b11###] and PIC-Sep [11  ###reference_b11###] with task-adaptive point sampling. While task-adaptive point sampling shows both strengths and limitations compared to FPS in the reconstruction task, it demonstrates clear superiority in the denoising, registration, and part segmentation tasks. Specifically, although task-adaptive point sampling yields an average CD loss that is  higher in reconstruction compared to FPS when using PIC-Sep [11  ###reference_b11###] as the ICL model, it significantly outperforms FPS across all other metrics and tasks. In addition, our proposed task-adaptive point sampling considerably enhances model performance without noticeably impacting inference speed.\nQuery-specific Prompt Sampling. We conduct two types of experiments, employing query-specific prompt sampling on FPS and task-adaptive point sampling, respectively. Our experimental results indicate that query-specific prompt sampling enhances overall performance. More importantly, the benefits of query-specific prompt sampling and task-adaptive point sampling are complementary. Specifically, task-adaptive sampling excels in enhancing denoising and part segmentation tasks, while query-specific prompt sampling boosts performance in reconstruction and registration tasks. As shown in Table 2  ###reference_###, combining task-adaptive point sampling with query-specific prompt sampling yields the best overall results, achieving significant performance improvements across all tasks. In addition, we find that these enhancements are achievable with only a threefold increase in inference time."

Specifically, we propose a Multi-grained In-Context Adaptive Sampling, dubbed MICAS, which includes task-adaptive point sampling and query-specific prompt sampling.\nThe former is engineered to interpret task information from diverse prompts and amalgamate it with the original point cloud, enabling a sampling approach that is tailored to each prompt. The latter involves identifying the most relevant prompt for each query, which provides more effective task guidance.\nTo our knowledge, this represents the inaugural exploration into point cloud sampling within an in-context learning framework at both point and prompt levels."

To evaluate the robustness of MICAS, we conduct an additional ablation experiment by replacing PointNet with DGCNN [56  ###reference_b56###], a model widely used for CNN-based high-level tasks on point clouds, such as classification and segmentation. Unlike PointNet [43  ###reference_b43###], which relies on a multilayer perceptron (MLP) architecture, DGCNN [56  ###reference_b56###] employs a dynamic graph CNN framework and introduces the EdgeConv operation. This operation effectively captures local geometric features of point clouds while maintaining permutation invariance.\nThe experimental results presented in Table A1  ###reference_###, show that the performance trend of MICAS remains consistent across in-context learning models, including PIC-Cat [11  ###reference_b11###] and PIC-Sep [11  ###reference_b11###], regardless of whether PointNet [43  ###reference_b43###] or DGCNN [56  ###reference_b56###] is used.

In contrast, MICAS effectively avoids these noisy points, focusing on more meaningful and valuable selections. In the reconstruction and registration tasks, MICAS outperforms PIC-Cat [11  ###reference_b11###] and PIC-Sep [11  ###reference_b11###] by producing target point clouds with clearer contours and more accurate shapes.\nSimilarly, in the part segmentation task, MICAS achieves accurate segmentation even in areas where PIC-Cat [11  ###reference_b11###] and PIC-Sep [11  ###reference_b11###] encounter segmentation errors.\nThese visualization results underscore the significance and effectiveness of our proposed MICAS in advancing point cloud in-context learning."

Specifically, in the query-specific prompt sampling, we prioritize selecting the \u201cbest-performing\u201d prompt from a sampled set of  candidate prompts. This process requires predicting the sampling probability for each of the  candidate prompts, which increases the model\u2019s inference time. As shown in Table  of the main paper, the query-specific prompt sampling introduces additional computation, adding approximately  ms to the inference time. Nonetheless, despite this slight increase in inference time, the query-specific prompt sampling achieves significant performance gains, particularly in the registration task.\nIn future work, we recommend addressing this limitation by making the prompt sampling module more lightweight and reducing the size of the prompt candidate pool. Specifically, a simplified prompt sampling module could be developed to streamline the prediction of sampling probabilities and enhance prediction speed. Furthermore, reducing the number of candidate prompts from  to  or even  would significantly lower the computational burden, thereby reducing the overall inference time."

Furthermore, the proposed MICAS contributes positively to the research community by advancing the field of point cloud processing and inspiring future innovations in adaptive in-context learning frameworks.\n###figure_5### ###figure_6###"

+    "abstract": "Modeling temporal characteristics and the non-stationary dynamics of body movement plays a significant role in predicting human future motions. However, it is challenging to capture these features due to the subtle transitions involved in the complex human motions. This paper introduces MotionWavelet, a human motion prediction framework that utilizes Wavelet Transformation and studies the human motion patterns in the spatial-frequency domain. In MotionWavelet, a Wavelet Diffusion Model (WDM) learns a Wavelet Manifold by applying Wavelet Transformation on the motion data therefore encoding the intricate spatial and temporal motion patterns. Once the Wavelet Manifold is built, WDM trains a diffusion model to generate human motions from Wavelet latent vectors. In addition to the WDM, MotionWavelet also presents a Wavelet Space Shaping Guidance mechanism to refine the denoising process to improve conformity with the manifold structure. WDM also develops Temporal Attention-Based Guidance to enhance the prediction accuracy. Extensive experiments validate the effectiveness of MotionWavelet, demonstrating improved prediction accuracy and enhanced generalization across various benchmarks. Furthermore, we showcase the capability of our method in different controllable motion prediction tasks. Our code and models will be released upon acceptance.",

Accurately predicting future human motion based on observed data is challenging due to the high complexity, variability, and stochastic nature of human motion.\nPrevious attempts [77  ###reference_b77###, 78  ###reference_b78###, 69  ###reference_b69###, 12  ###reference_b12###] typically directly use the high dimensional motion data in capturing the complex temporal and spatial dynamics of human movement, which hinders their performance in motion prediction with the sparse observational data.\nConsidering this challenge, there is considerable research on neuromechanics of human motions [13  ###reference_b13###, 81  ###reference_b81###, 23  ###reference_b23###, 16  ###reference_b16###, 55  ###reference_b55###] verify that human motion is intrinsically linked to the frequency domain. These key observations motivate some methods to model human motion [25  ###reference_b25###, 61  ###reference_b61###, 82  ###reference_b82###, 7  ###reference_b7###, 71  ###reference_b71###] in the frequency domain to synthesize or predict motions. This frequency decomposition fashion of motion simplifies the capture of periodic movement features, ultimately enhancing predictive accuracy in the modeling process of human motion.\nDespite the progress in motion frequency modeling, these methods still struggle to model details of the motion sequences. Specifically, previous phase-based representations in the frequency domain [62  ###reference_b62###, 25  ###reference_b25###, 61  ###reference_b61###, 46  ###reference_b46###, 60  ###reference_b60###, 36  ###reference_b36###] take the Fourier phase components to model temporal dynamics. However, windowed Fourier analysis struggles to capture non-stationary signals due to its limited window size, impeding its adaptability to capture local frequency variations and handling abrupt, non-stationary signals. Besides, existing DCT-based methods [7  ###reference_b7###, 64  ###reference_b64###, 1  ###reference_b1###, 71  ###reference_b71###] directly eliminate high-frequency components in the frequency domain, overlooking critical details and diminishing predictive accuracy.\nTo resolve these issues, we introduce MotionWavelet, a novel data-driven method for human motion prediction that utilizes a Motion Wavelet Manifold derived from human motion data and a Wavelet Diffusion Model for motion prediction. Different from previous phase-based representations in the frequency domain, the motion wavelet manifold models the motion sequence as a whole, excelling in modeling dynamic transitions where periodicity assumptions often break down (see Sec. 4.7.1  ###reference_.SSS1###). Besides, in contrast to the DCT-based frequency methods of ignoring high-frequency motion signals, the motion wavelet manifold models both high-frequency and low-frequency signals along the temporal and spatial axes, explicitly. As a result, the wavelet manifold offers enhanced adaptability to varying frequency changes, enabling the capture of both local temporal characteristics and non-stationary dynamics. This detailed modeling allows MotionWavelet to effectively represent subtle transitions and intricate movements, providing a robust foundation for predicting complex human motion patterns. Additionally, we provide a comprehensive study on the influence of different wavelet bases for human motion representation, offering valuable guidance for motion embedding using the wavelet transform.\nOnce we define the learned wavelet manifold, our approach leverages this manifold to predict future motions based on limited short-term movement observations. We introduce a Wavelet Motion Diffusion (WDM) model, wherein the diffusion model effectively captures the motion distribution in the wavelet domain, enabling accurate human motion prediction. Technically, during iterative denoising, previous methods [7  ###reference_b7###, 64  ###reference_b64###, 1  ###reference_b1###, 71  ###reference_b71###] often apply sequential denoising directly to noisy inputs, which are misaligned with underlying manifold structures and reduce predictive accuracy. In contrast, in this work, we do not use the mask-completion fashion and predict motions with observed motion wavelets classifier-free guidance. To additionally improve the guidance controlablity, we propose Wavelet Manifold Shaping Guidance to enhance the prediction precision.\nSpecifically, Wavelet Manifold Shaping Guidance map the output of denoiser via an Inverse DWT to recover motion signals, then reapply a DWT operation returning it into the wavelet manifold. Aligning the latent space with wavelet manifolds enables a structured progression of denoising steps, improving the quality and fidelity of generated results while stabilizing latent space noise and smoothing transitions across the diffusion trajectory, which is shown in Sec. 4.7.3  ###reference_.SSS3###. Besides, we delve into the self-attention mechanism of the noise prediction network and find the self-attention mechanism mainly mines the motion coherence in the temporal dimension. Based on this observation, we propose Temporal Attention-Based Guidance to further enhance predictive accuracy during the denoising process. By adaptively weighting the influence of different time steps according to the attention score, this approach emphasizes critical wavelet features while suppressing irrelevant noise (see Sec. 4.7.4  ###reference_.SSS4###), enabling a more accurate alignment with the target motion trajectory.\nWe conduct extensive experiments to demonstrate the effectiveness of our method. MotionWavelet achieves high predictive accuracy and generalizability across a broad range of benchmarks, highlighting its capability to handle complex motions and diverse movement styles. A comprehensive evaluation and analysis are presented to validate the effectiveness of all key design components in MotionWavelet."

Various model architectures have been explored in these studies. For instance, some earlier works [18  ###reference_b18###, 37  ###reference_b37###, 2  ###reference_b2###] utilize Long Short-Term Memory (LSTM) networks [21  ###reference_b21###], while MOJO [86  ###reference_b86###] applies the Gated Recurrent Unit (GRU) [10  ###reference_b10###], and Transformer structures [67  ###reference_b67###] have also been explored in this context [41  ###reference_b41###, 71  ###reference_b71###].

Generative Adversarial Networks (GANs) have been utilized by framing the prediction task as a generative process [22  ###reference_b22###].

Given that human body movement is intrinsically linked to the frequency domain, as evidenced by neuroscience findings, e.g., neuromechanics of human movement [13  ###reference_b13###, 81  ###reference_b81###, 23  ###reference_b23###, 16  ###reference_b16###], frequency domain approaches have been proposed for a variety of motion-related tasks [7  ###reference_b7###, 45  ###reference_b45###, 46  ###reference_b46###, 66  ###reference_b66###, 4  ###reference_b4###, 42  ###reference_b42###, 63  ###reference_b63###, 80  ###reference_b80###], such as motion editing [4  ###reference_b4###] and motion generation [42  ###reference_b42###, 61  ###reference_b61###, 25  ###reference_b25###]. Inspired by the previous efforts, in this paper, we present the first application of wavelet manifold diffusion for motion prediction, enhancing guidance for wavelet manifold denoising.\nDenoising Diffusion Model. Denoising Diffusion models [58  ###reference_b58###, 59  ###reference_b59###, 24  ###reference_b24###] have recently demonstrated impressive performance across various generation tasks, including 2D image synthesis [84  ###reference_b84###, 52  ###reference_b52###, 53  ###reference_b53###], 3D shape generation [38  ###reference_b38###, 43  ###reference_b43###, 76  ###reference_b76###, 70  ###reference_b70###, 83  ###reference_b83###, 65  ###reference_b65###], and motion synthesis [56  ###reference_b56###, 44  ###reference_b44###, 87  ###reference_b87###, 8  ###reference_b8###, 28  ###reference_b28###, 68  ###reference_b68###, 85  ###reference_b85###, 6  ###reference_b6###, 11  ###reference_b11###]. In human motion prediction, diffusion models have also been employed. For instance, [3  ###reference_b3###] introduces a latent diffusion model tailored for behavior-driven human motion prediction, while MotionDiff [71  ###reference_b71###] utilizes a spatial-temporal transformer-based diffusion network to generate diverse and realistic motions, with a graph convolutional network refining the outputs.

However, we observe that such methods may not be fully optimal when dealing with complex wavelet manifolds, as the directional trajectory of denoising steps can diverge from the natural structure of wavelet manifolds. This misalignment can hinder the predictive accuracy and efficiency of the denoising process. To address this, we propose the Wavelet Manifold Shaping Guidance (WMSG) technique, which integrates a wavelet transform at the end of each iteration to refine the noisy manifold. Specifically, instead of directly applying the subsequent denoising process to the wavelet manifold  obtained from Eq. 6  ###reference_###, we first map the output of each step via Inverse Discrete Wavelet Transform (iDWT), , which gives a motion sequence . Next, we convert the  to wavelet manifold using Discrete Wavelet Transform (DWT) . The process unfolds as follows,\nBy shaping the latent space in alignment with the wavelet manifolds, this approach facilitates a more structured progression of denoising steps, enhancing both the quality and fidelity of the generated results. This guidance also effectively stabilizes the noise in the wavelet latent space and smoother transitions across timesteps. We validate the effectiveness of the design in Sec. 4.7.3  ###reference_.SSS3###.\nTo further improve the predictive accuracy during the denoising process, we introduce Temporal Attention-Based Guidance (TABG) during the sampling. An overview of TABG is given in Fig. 2  ###reference_###.

The results validate the effectiveness of WMSG in guiding the denoising process along the wavelet manifold."

By constructing a Wavelet Manifold from motion data and applying wavelet diffusion, our method captures motion features in the spatial-frequency domain, allowing effective modeling of both global and local temporal characteristics, as well as the non-stationary dynamics. We introduce the Wavelet Diffusion Model to model discriminative features from the motion wavelet manifold and improve predictive performance through Wavelet Manifold Shaping Guidance and Temporal Attention-Based Guidance mechanisms. Extensive experiments validate the effectiveness of MotionWavelet, demonstrating remarkably improved prediction accuracy and generalization across different benchmarks."

Previous challenges included problems like Treewidth, Feedback Vertex Set, Cluster Editing or Vertex Cover. This years challenge was announced in November 2023 and the submission deadline was in June 2024. The challenge consisted of three tracks. In the Exact Track, the solver has 30 minutes to find the optimal solution for the problem instance. In the Heuristic Track, the goal is to find the best possible solution within 5 minutes. The last track is the Parameterized Track, which is similar to the exact track because the solver has 30 minutes to find the optimal solution but additionally all instances have small cutwidth.\nIt was required that all solvers are single threaded and each solver is limited to 8GB of memory.\nThe solvers were tested on 200 instances for each track (100 of those were known during the competition) and we used those to test our solvers while developing them.\nIn Figure 1  ###reference_### we can see an example instance with the PACE naming scheme and a corresponding optimal solution to this instance."

For a complete graph, this results in  constraints in the worst case. Besides the aforementioned issues for the linear ordering ILP, even enumerating all these cycles is computationally hard.\nTo address these challenges, we employ a row generation technique. This approach iteratively adds constraints until a valid solution is found, mitigating memory usage and numerical stability issues.\nFor the linear ordering formulation, we initially remove all transitive constraints and solve the ILP. We then verify if the variables form a valid linear ordering. If not, we add only those transitive constraints that contradict the current solution. This process is repeated until a valid solution is obtained.\nFor the cycle-based formulation, we need not only to generate constraints but also to lazily generate cycles, as enumerating all cycles is computationally too expensive even for small graphs.

This approach serves as a heuristic for graph  and has superior performance in our tests compared to recalculating an FAS heuristic at each iteration.

This efficiency is attributed to our strategy in line 5 of Algorithm 1  ###reference_thm1###, where we consistently add only the shortest cycles, resulting in relatively short cycles for branching.\nTo enhance the efficiency of our branch and bound algorithm, we add a packing lower bound. This is computed by searching for a set of edge-disjoint cycles . A simple lower bound can then be calculated as:\nWe further improve this lower bound by allowing cycles to share edges in special cases. The procedure is as follows: We initialize a lower bound counter with 0. Then, we iterate through every cycle  and search for the edge  with the smallest weight in . We increment our lower bound by  and subtract  from the weight of each .\nTo cut branches more effectively, we implemented a local search heuristic based on the work of Lan et al.

+    "title": "PATHS: A Hierarchical Transformer for Efficient Whole Slide Image Analysis",
+    "abstract": "Computational analysis of whole slide images (WSIs) has seen significant research progress in recent years, with applications ranging across important diagnostic and prognostic tasks such as survival or cancer subtype prediction. Many state-of-the-art models process the entire slide \u2013 which may be as large as  pixels \u2013 as a bag of many patches, the size of which necessitates computationally cheap feature aggregation methods. However, a large proportion of these patches are uninformative, such as those containing only healthy or adipose tissue, adding significant noise and size to the bag.\nWe propose Pathology Transformer with Hierarchical Selection (PATHS), a novel top-down method for hierarchical weakly supervised representation learning on slide-level tasks in computational pathology. PATHS is inspired by the cross-magnification manner in which a human pathologist examines a slide, recursively filtering patches at each magnification level to a small subset relevant to the diagnosis. Our method overcomes the complications of processing the entire slide, enabling quadratic self-attention and providing a simple interpretable measure of region importance. We apply PATHS to five datasets of The Cancer Genome Atlas (TCGA), and achieve superior performance on slide-level prediction tasks when compared to previous methods, despite processing only a small proportion of the slide.",

+            "text": "Whole slide images (WSIs) \u2013 high resolution scans of sliced biopsy sections \u2013 are the basis for pathologists to diagnose and analyse disease. Due to the importance and scale of this task, recent years have seen the development of a range of automated approaches to assist in processing and analysis, with particular success seen in the application of modern computer vision methods [10  ###reference_b10###]. However, the gigapixel scale of WSIs, coupled with their pyramidal structure, challenges the application of standard vision architectures such as convolutional neural networks [13  ###reference_b13###, 27  ###reference_b27###] and vision transformers [11  ###reference_b11###] at the slide level.\nWhen pathologists inspect whole slide images, they usually do so in a top-down manner: identifying regions of interest and tissue architecture (such as areas of cancerous tissue) at low magnification before investigating these areas further at greater magnification. To inspect the entire slide at its maximum resolution would be unduly time-consuming and largely uninformative, with only certain areas of the slide providing useful information. Conversely, most state-of-the-art deep learning methods process the slide in its entirety at high magnification, splitting the image into a large collection of small (e.g., px) patches, in the order of magnitude of  per slide [10  ###reference_b10###, 2  ###reference_b2###]. This incurs a high computational cost, and in many cases provides a large amount of uninformative data to the model, effectively creating a poor signal-to-noise ratio. Within this category, the most common approach is multiple instance learning (MIL), in which each slide is treated as a large unordered bag of patches that are processed using pre-trained computer vision models, and globally aggregated to produce slide-level representations [2  ###reference_b2###, 22  ###reference_b22###, 15  ###reference_b15###, 16  ###reference_b16###]. The global aggregation method must be efficient due to the scale of the bag; self-attention, for example, is infeasible, necessitating the use of less performant linear-time approximations [26  ###reference_b26###, 31  ###reference_b31###]. Past approaches to mitigating computational overheads include selecting only a small proportion of patches by random selection [30  ###reference_b30###] or\nmanual clustering-based heuristic [14  ###reference_b14###]. However, such manual heuristics are suboptimal as they are error-prone and often inflexible. More recent work adapts hierarchical methods, which have seen success in the domain of computer vision, to WSIs [34  ###reference_b34###, 4  ###reference_b4###, 21  ###reference_b21###, 6  ###reference_b6###].\nWhile more expressive than MIL, hierarchical methods nevertheless necessitate the pre-processing of the entire slide at its full magnification and require the use of self-supervision rather than task-specific training due to the large number of patches.\n###figure_1### In this paper, we propose the Pathology Transformer with Hierarchical Selection (PATHS) \u2013 a top-down hierarchical model \u2013 as a novel weakly supervised approach to learning on WSIs, combining the effectiveness of hierarchical methods with the data efficiency of patch sampling (summarised in Figure 1  ###reference_###).\nMuch like a pathologist, our model initially processes the slide at a low magnification, capturing high-level tissue structure, before an attention mechanism recursively identifies regions of importance. The regions of highest importance are magnified and the process is repeated, retaining information from lower magnifications in the form of a hierarchy. This enables the capture of information across a range of resolutions while avoiding the costly processing of the entire slide. We show that PATHS exhibits several desirable properties for slide-level tasks in computational pathology:\nHigh accuracy on five WSI datasets, covering different cancer sites, achieving comparable or improved performance on a survival prediction task compared to state-of-the-art methods. Our proposed dynamic patch selection and multi-resolution slide context drive this performance, reading in fewer uninformative slides at each magnification and thus improving the signal-to-noise ratio.\nComputational efficiency by only processing a fraction of the slide at each magnification, leading to a speed-up exceeding a factor of ten in inference time at  magnification compared to MIL.\nA clinically meaningful heuristic for patch selection that mimics the workflow of a pathologist.\nTop-down patch selection can be used for debugging and validation. Explicit identification of regions of interest enables visualisation of the learned traversal through the WSI\u2019s hierarchical structure, and provides interpretable model behaviour."

Due to this large scale, multiple instance learning (MIL) [2  ###reference_b2###, 16  ###reference_b16###, 30  ###reference_b30###] is frequently used in computational pathology tasks. Multiple instance learning treats each slide as a large unordered bag of low-resolution patches (e.g.,  px) at a fixed magnification level.\nGeneral-purpose MIL approaches include ABMIL [15  ###reference_b15###], which introduces an attention-based aggregation as a global weighted sum, where the per-patch weights are scalars produced as a learnable function of the patch feature. Given the success of self-attention in the domain of vision [11  ###reference_b11###, 21  ###reference_b21###], several works have explored self-attention based MIL aggregation [26  ###reference_b26###].\nHowever, in the context of computational pathology, the scale of the WSIs precludes the use of full self-attention, due to quadratic scaling with respect to the sequence length [29  ###reference_b29###], forcing these methods to use less performant compromises such as linear-time approximations [31  ###reference_b31###] or cross-attention with a smaller set [5  ###reference_b5###].\nTo mitigate the issues caused by the large scale of WSIs, related work has focused on reducing the bag size through random or heuristic-based sampling, or the clustering of patches into smaller bags [30  ###reference_b30###, 14  ###reference_b14###, 32  ###reference_b32###]. Graph neural networks have seen use as an aggregator of randomly sampled patches, accounting for spatial interactions [19  ###reference_b19###, 35  ###reference_b35###]. However, these non-parametric patch sampling methods risk missing important sections of the slide, and may fail to adequately represent large-scale features. More recently, Thandiackal et al. [28  ###reference_b28###] propose ZoomMIL, a cross-magnification MIL method which selects patches in a learnable manner through an adapted differentiable patch selection algorithm [8  ###reference_b8###], removing the need for manual heuristics. The benefits of incorporating patch features from multiple magnification levels has been observed in other work, demonstrating the potential of this technique to improve slide-level representations in MIL [18  ###reference_b18###, 17  ###reference_b17###]. Regardless, these methods remain limited by the set-based nature of MIL, in which the overall structure of the slide, and spatial relationships between patches, are lost due to the discarding of positional information.\nHierarchical Methods Hierarchy-based image processing enables positional contextualisation of image patches and processing across multiple image scales, extending efficiently to large images [4  ###reference_b4###, 34  ###reference_b34###, 21  ###reference_b21###]. Rather than globally aggregating the image in one step, as in most MIL approaches, the grid of patches is repeatedly aggregated across spatially local steps. The resulting features form a hierarchy, where higher levels represent larger regions of the image, with the topmost level containing a single global feature.\nIn the context of computational pathology, Chen et al. [6  ###reference_b6###] propose Hierarchical Image Pyramid Transformer (HIPT), which improves expressivity over the standard set-based MIL methods, enabling the capture of macro-scale features and large cell structures in the slide. However, as training on entire slides in an end-to-end manner is computationally infeasible, training is split into several distinct stages, each corresponding to a single magnification and level of the hierarchy. Due to a lack of patch-level labels, all but the last stage must be pre-trained using a self-supervised method [3  ###reference_b3###], which could lead to the inclusion of redundant visual information (such as scanning artefacts, background proportion, biopsy shape). More notably, however, these approaches operate in a bottom-up manner: the slide is initially processed as a grid of patches at the highest magnification (the bottom level of the hierarchy), with subsequent processing moving up the hierarchy to the lower magnification levels. This necessitates costly processing of a large number of patches per slide, likely including many of low relevance to the downstream task. We, therefore, propose a top-down approach, which retains the hierarchical structure, while iteratively selecting substantially smaller but important areas of the slide."

We cross-validate our method across five folds for each dataset, using the same folds for each model.\nBaselines\nWe compare PATHS to a number of state-of-the-art weakly-supervised baselines:\nABMIL [15  ###reference_b15###]: Attention-Based Multiple Instance Learning (ABMIL) is a simple MIL variant. Scalar attention values are produced per patch, and used as weights in a global sum for slide-level aggregation.\nDeepAttnMISL [32  ###reference_b32###]: Variant of ABMIL, with the addition of phenotype-based clustering.\nGCN-MIL [19  ###reference_b19###, 35  ###reference_b35###]: A GNN-based MIL approach.

The bottom two stages are trained in a self-supervised manner using DINO [3  ###reference_b3###]. Due to its hierarchical nature, we consider this baseline an important comparison for our work.\nZoomMIL [28  ###reference_b28###]: A MIL approach in which patches are selected from multiple magnifications via a differentiable zooming procedure. We configure ZoomMIL to sample the same number of patches as PATHS at each magnification for fair comparison (further details in Appendix B  ###reference_###).\nWhile all models are evaluated on the same folds and datasets, the results for ABMIL, DeepAttnMISL, GCN-MIL, DS-MIL and HIPT use pre-calculated risk scores for these folds, as reported in [6  ###reference_b6###].\nSetup It is common to process whole slide images at  or  magnification to capture the details of individual cells [6  ###reference_b6###, 15  ###reference_b15###, 5  ###reference_b5###, 22  ###reference_b22###]. In all experiments, we select  magnification as the bottom level of the hierarchy , and  as the top, ensuring that  is of tractable size of all slides, leading to five magnification levels. We also set , causing a fixed limit of  patches per slide at each magnification, a small fraction of the total (which may be as many as tens of thousands).\nTo train the model for survival prediction we use the censored negative log-likelihood training objective  [33  ###reference_b33###] with . We quantise patient survival times into  buckets such that each bucket contains roughly an equal number of uncensored patients. The model outputs  logits, corresponding to the survival hazards for each bucket, from which  may be computed. We set  in all experiments.\nWe evaluate using the censored concordance index metric (c-index), which measures the proportion of comparable patient pairs (those in which one can tell with certainty the order in which the events occurred) for which the model\u2019s survival prediction is concordant, as is standard. Random choice achieves a score of , while the best possible score is . All experiments were run on a single Nvidia A100 80GB GPU. See Appendix B  ###reference_### for a complete list of hyperparameters. The code to reproduce the experiments is available at https://github.com/zzbuzzard/PATHS  ###reference_###.\nPatch Embedding We pre-process all patches using a pre-trained image encoder , avoiding the heavy I/O and computation cost of reading and processing the patches during training. The results are stored as a two dimensional array of features, rather than an unordered bag as in MIL, to preserve positional information. Furthermore, unlike traditional MIL techniques, we must pre-process patches at several magnification levels, rather than at the highest magnification only: the total number of patches to be pre-processed per slide is  rather than . However, note that  forms a geometric sequence, as each time magnification is reduced by a factor of , the number of patches  falls by a factor of . In the case of , which we use in all experiments, our method incurs a pre-processing overhead of a factor of . Note that this overhead is only required to accelerate training, and during inference only the selected patches  are extracted from each level. This is in contrast to past work, in which a new slide must be fully patched and pre-processed before inference begins, incurring high latency.\nIn this work, we employ UNI [7  ###reference_b7###] as our patch encoder .

Compared to ABMIL, DeepAttnMISL, GCN-MIL, DS-MIL and HIPT, all of which process the entire slide as tens of thousands of patches at  magnification, PATHS processes just several hundred patches per slide. Despite this, we achieve a significant improvement in model accuracy, highlighting the benefit of processing a smaller number of more relevant patches. The improvement over ZoomMIL, which similarly filters the patches to a small subset per slide, demonstrates the advantage of PATHS over MIL architectures.\nInference Speed When vision models are incorporated into practical tools for computational pathology, it is imperative to achieve low computational overhead and inference latency, since computational resources are often limited in a clinical setting. Whilst large-scale offline preprocessing of patch features enables fast training for \u2018full slide\u2019 methods (i.e., those which must process all tissue-containing patches at high magnification, such as ABMIL or HIPT), this workaround does not extend to inference time. When applied to a new slide in a clinical setting, the entire slide must first be loaded into memory and processed using the patch embedding network (which may be a large network, such as UNI), leading to significant latency even on high performance infrastructure. Figure 3  ###reference_### demonstrates that, by significantly reducing the number of patches required from each slide, PATHS significantly improves inference latency over full slide approaches. This is a key advantage of our method, as this preprocessing step is the dominant processing cost for both PATHS and full slide models at inference time, taking up over 99% of inference time in our experiments. Note that, even on state-of-the-art hardware and at just  magnification (while  is common), a minimal full slide approach takes over a minute to process a single new slide on average. It is reasonable to assume that latency will be significantly larger in practice, especially in the case of models running locally on clinical hardware to ensure patient confidentiality. Appendix C  ###reference_### provides further details on the number of patches loaded by each approach (which is roughly proportional to inference latency) for a hardware-independent comparison of efficiency.\n###figure_3### The main novelties of PATHS are the learnable patch selection module, combined with the patch- and slide-level context, allowing the propagation of cross-magnification information down the hierarchy. To investigate the contribution of each module to the overall performance of PATHS, we carry out an ablation study (Table 2  ###reference_###) in which we evaluate several variants of our architecture on the five datasets used in Table 1  ###reference_###.\nCross-magnification Context Improves Over MIL With both hierarchical and slide-level context removed, our model becomes similar to a single magnification MIL method. The drop in performance highlights the advantage of our method over MIL, although the score remains relatively strong across the datasets, likely due to the strength of transformer-based aggregation over a small set of extracted relevant patches. The addition of either hierarchical or slide-level context further improves performance, particularly that of slide-level context, demonstrating the benefit of incorporating cross-magnification information, as observed in other work [18  ###reference_b18###, 6  ###reference_b6###, 17  ###reference_b17###]. However, it should be noted that for the LUAD dataset, on which PATHS performs poorly, the removal of context leads to improved performance. As both ZoomMIL and HIPT also perform poorly on LUAD (Table 1  ###reference_###), we hypothesise that cross-magnification information may be of low importance on this particular dataset and task, as evidenced by the strong performance of single magnification methods such as ABMIL.\nBenefit of the Learned Sampling Heuristic Next, we investigate the significance of extracting patches based on the predicted importance . This is achieved through the replacement of the importance MLP () with a random distribution  at inference time, leading to the selection of random areas of the slide (although background patches are still excluded). Interestingly, this modification leads to only a small reduction in performance. This result is supported by past work: Wulczyn et al. [30  ###reference_b30###] achieve reasonable performance in a multiple instance learning pipeline using just 16 random patches from each slide, which the authors argue are very likely to contain at least one relevant (e.g., tumorous) patch. Our method uses both a higher number of patches (at most 80 per level) and multiple magnification levels, greatly increasing the likelihood of capturing relevant information under random selection. However, random sampling foregoes the interpretability benefits of attentional sampling, which allow us to easily inspect model behaviour.\nInterpretability The quantification of patch importance (via ) enables model interpretability through the explicit identification of regions of interest. Figure 4  ###reference_### visualises the patches selected by PATHS on three CAMELYON17 [20  ###reference_b20###] slides, alongside manually annotated tumour regions. Note that PATHS was not trained on CAMELYON17, but instead applied in a zero-shot setting, following training on TCGA-BRCA.\n###figure_4### ###figure_5### ###figure_6### The \u2018heat\u2019 value for each pixel is given by the sum of the encapsulating patch importances at each magnification level, with  weighted by factor of  to prevent excessive heat in the areas selected across all magnification levels. PATHS appears to correctly identify tumorous regions, and avoids adipose tissue and areas of low tissue density \u2013 despite receiving only weak slide-level supervision. As a small and fixed number of patches () are retained at each magnification level, it is to be expected that not all of the tumorous tissue is selected, and indeed that less relevant patches may be selected in the absence of tumour."

In this work, we present an alternative approach, in which we filter the processed data to a small subset of relevant patches across several magnification levels. While the recent work of Thandiackal et al. [28  ###reference_b28###] explores a similar motivation, we approach this problem from the perspective of improving the efficiency of hierarchical processing, rather than extending MIL to multiple magnifications via learnable patch selection,\nleading to a more expressive and performant (non-MIL) model that views each patch in context. We note that, unlike ZoomMIL, our patch selection algorithm is not differentiable (due to the top-K operation within Filter), but we do not find this necessary for strong performance, instead learning  via a gating mechanism. Despite processing strictly less data than most baselines we compare to, PATHS achieves superior performance on average across five large cancer datasets. While we evaluate on survival prediction tasks, PATHS is applicable to arbitrary weakly-supervised tasks and other large-scale image data.\nOur ablation study (Table 2  ###reference_###) demonstrates that incorporating data from multiple magnification levels, here in the form of context, is beneficial for performance. While high magnification patches allow the modelling of cellular-level features of the slide, patches at lower magnification provide convenient representations of higher-level features of the slide, such as the general organisation of the tissue. Our work therefore supports the hypothesis that performance may be improved through the incorporation of patches across magnification levels, as suggested by past work [18  ###reference_b18###, 17  ###reference_b17###].\nPATHS leverages UNI, which like most domain specific patch encoding models, was trained exclusively on patches at high magnification power (). However, PATHS requires the encoding of patches across a range of magnifications, including patches at very low magnification, and we therefore hypothesise that performance may be further improved using a cross-magnification pre-trained patch encoder.\nOur results support the hypothesis that processing large numbers of patches is often unnecessary for achieving strong performance on practically relevant tasks such as survival prediction.\nIn fact, by reducing the number of patches input to PATHS we obtained improved performance. It allows for the unimpeded use of a transformer architecture (usually restricted by huge sequence lengths), significantly lower memory requirements, faster training times, and an improved signal-to-noise ratio (by excluding patches of low relevance). However, the thin margin between random and attentional patch selection, as observed in Table 2  ###reference_###, indicates room for improvement in this area, which we leave to future work.\nThe modelling of explicit important values  is an additional benefit of our approach, and highly relevant in a clinical setting.\nDespite receiving only weak slide-level supervision, PATHS is capable of identifying important (tumorous) areas of the slide. This capability allows for valuable insights into the model\u2019s behaviour, which may ultimately lead to better understanding of the disease."

Otsu\u2019s method is used in the Filter function to identify background patches.\nIn both cases, patches are loaded from disk using a single CPU thread, and pre-processing and model inference takes place on a single A100 GPU. In all experiments, loading and pre-processing the patches using UNI takes over 99% of the total time (and over 99.99% for the example MIL model), despite PATHS loading fewer patches. Figure 5  ###reference_### gives the corresponding number of patches loaded by each method, providing a measure of inference efficiency independent of hardware or image encoder.\n###figure_7###"

To evaluate the importance of domain specific encoding for PATHS, we compare using UNI to using an ImageNet pre-trained ResNet50, and observe weaker performance in the latter case. We then compare two models trained specifically on WSI patches, a self-supervised vision transformer trained on a number of TCGA datasets at  magnification [6  ###reference_b6###] and UNI, a vision transformer trained on patches across many different tissue types, also at  [7  ###reference_b7###]. As discussed in Section 6  ###reference_###, PATHS processes patches at magnifications strictly less than  in our experiments \u2013 between  and  \u2013 which are out of domain inputs for both models. Due to its larger scale, high-resolution fine-tuning, and exposure to a larger number of tissue types, UNI appears to create superior representations of these low magnification patches, leading to stronger performance. We therefore select UNI as our image encoder. However, we emphasise that performance of PATHS may be improved further through the use of an image encoder pre-trained on WSI patches at lower magnification."

+    "title": "Efficient Nonlinear Function Approximation in Analog Resistive Crossbars for Recurrent Neural Networks",
+    "abstract": "Analog In-memory Computing (IMC) has demonstrated energy-efficient and low latency implementation of convolution and fully-connected layers in deep neural networks (DNN) by using physics for computing in parallel resistive memory arrays. However, recurrent neural networks (RNN) that are widely used for speech-recognition and natural language processing have tasted limited success with this approach. This can be attributed to the significant time and energy penalties incurred in implementing nonlinear activation functions that are abundant in such models. In this work, we experimentally demonstrate the implementation of a non-linear activation function integrated with a ramp analog-to-digital conversion (ADC) at the periphery of the memory to improve in-memory implementation of RNNs. Our approach uses an extra column of memristors to produce an appropriately pre-distorted ramp voltage such that the comparator output directly approximates the desired nonlinear function. We experimentally demonstrate programming different nonlinear functions using a memristive array and simulate its incorporation in RNNs to solve keyword spotting and language modelling tasks. Compared to other approaches, we demonstrate manifold increase in area-efficiency, energy-efficiency and throughput due to the in-memory, programmable ramp generator that removes digital processing overhead.",

+            "text": "Artificial Intelligence (AI) algorithms, spurred by the growth of deep neural networks (DNN), have produced the state-of-the-art solutions in several domains ranging from computer vision[1  ###reference_b1###], speech recognition[2  ###reference_b2###], game playing[3  ###reference_b3###] to scientific discovery[4  ###reference_b4###], natural language processing[5  ###reference_b5###] and more. The general trend in all these applications has been increasing the model size by increasing the number of layers and the number of weights in each layer. This trend has, however, caused growing concern in terms of energy efficiency for both edge applications and servers for training; power is scarce due to battery limits in edge devices while the total energy required for training large models in the cloud raises environmental concerns. Edge devices have a further challenge posed by strong latency requirements in applications such as keyword spotting to turn on mobile devices, augmented reality and virtual reality platforms, anti-collision systems in driverless vehicles etc.\nThe bottleneck for implementing DNNs on current hardware arises due to the frequent memory access necessitated by the von Neumann architecture and the high memory access energy for storing the parameters of a large model[6  ###reference_b6###]. As a solution to this problem, a new architecture of In-memory Computing (IMC) has become increasingly popular. Instead of reading and writing data from memory in every cycle, IMC allows neuronal weights to remain stationary in memory with inputs being applied to it in parallel and the final output prior to neuronal activation being directly read from memory. Among the IMC techniques explored, analog/mixed-signal IMC using non-volatile memory devices such as memristive[7  ###reference_b7###] ones have shown great promise in improving latency, energy and area efficiencies of DNN training[8  ###reference_b8###, 9  ###reference_b9###, 10  ###reference_b10###] and inference[11  ###reference_b11###, 12  ###reference_b12###, 13  ###reference_b13###], combinatorial optimization[14  ###reference_b14###, 15  ###reference_b15###], hardware security[16  ###reference_b16###, 11  ###reference_b11###], content addressable memory[17  ###reference_b17###], signal processing[18  ###reference_b18###, 19  ###reference_b19###, 20  ###reference_b20###] etc. It should be noted that analog IMC does not refer to the input and output signals being analog; rather, it refers to the storage of multi-bit or analog weights in each memory cell (as opposed to using memristor for 1-bit storage[21  ###reference_b21###, 22  ###reference_b22###]) and using analog computing techniques (such as Ohm\u2019s law, Kirchoff\u2019s law etc.) for processing inputs. Analog weight storage[23  ###reference_b23###] enables higher density of weights as well as higher parallelism (by enabling multiple rows simultaneously) compared to digital counterparts.\nComparing the energy efficiency and throughput of recently reported DNN accelerators (Fig. 1  ###reference_###a) shows the improvements provided by IMC approaches over digital architectures. However, taking a closer look based on DNN architecture exposes an interesting phenomenon\u2013while analog IMC has improved energy efficiency of convolutional and fully connected layers in DNNs, the same cannot be said for recurrent neural network (RNN) implementations such as long short term memory (LSTM)[24  ###reference_b24###, 25  ###reference_b25###, 26  ###reference_b26###, 27  ###reference_b27###, 28  ###reference_b28###]. Resistive memories store the layer weights in their resistance values, inputs are typically provided as pulse widths or voltage levels, multiplications between input and weight happen in place by Ohm\u2019s law, and summation of the resulting current occurs naturally by Kirchoff\u2019s current law. This enables an efficient implementation of linear operations in vector spaces such as dot products between inputs and weight vectors. Early implementations of LSTM using memristors have focussed on achieving acceptable accuracy in network ouptut in the presence of programming errors. A  1T1R array[29  ###reference_b29###] was shown to be able to solve real-life regression and classification problems while 2.5M phase-change memory devices[30  ###reference_b30###] have been programmed to implement LSTM for language modeling. While these were impressive demonstrations, energy efficiency improvements were limited, since RNNs such as LSTMs have a large fraction of nonlinear (NL) operations such as sigmoid and hyperbolic tangent being applied as neuronal activations (Fig. 1  ###reference_###b). With the dot products being very efficiently implemented in the analog IMC, the conventional digital implementation of the NL operations now serves as a critical bottleneck.\n###figure_1### As an example, an RNN transducer was implemented on a 34-tile IMC system with 35 million phase-change memory (PCM) devices and efficient inter-tile communication[32  ###reference_b32###]. While the system integration and scale of this effort[32  ###reference_b32###] is very impressive, the NL operations are performed off-chip using low energy efficiency digital processing reducing the overall system energy efficiency. Another pioneering research[23  ###reference_b23###] integrated 64 cores of PCM arrays for IMC operations with on-chip digital processing units for NL operations. However, the serial nature of the digital processor, which is shared across the neurons in 8 cores, reduced both the energy efficiency and throughput of the overall system. This work used look-up tables (LUT), similar to other works[33  ###reference_b33###, 34  ###reference_b34###, 35  ###reference_b35###]; alternate techniques using cordic[36  ###reference_b36###] or piece wise linear approximations[37  ###reference_b37###, 24  ###reference_b24###, 38  ###reference_b38###, 39  ###reference_b39###] or quadratic polynomial approximation[40  ###reference_b40###] have also been proposed to reduce overhead and latency () of computing one function. However, it is the big difference in parallelism of crossbars versus serial digital processors which causes this inherent bottleneck. Even in a hypothetical situation with an increased number of parallel digital computing engines for the NL activations (Fig. 1  ###reference_###c, Supplementary Section Supplementary Note S6.  ###reference_6###), albeit at a large area penalty, the latency of the NL operations still dominates the overall latency due to the extremely fast implementation of vector-matrix-multiplication (VMM) in memristive crossbars.\nIn this work, we introduce a novel in-memory analog to digital conversion (ADC) technique for analog IMC systems that can combine nonlinear activation function computations in the data conversion process (Fig. 1  ###reference_###d), and experimentally demonstrate its benefits in an analog memristor array. Utilizing the sense amplifiers (SA) as a comparator in ramp ADC, and creating a ramp voltage by integrating the current from an independent column of memristors which are activated row by row in separate clock cycles, an area-efficient in-memory ADC for memristive crossbars is demonstrated. However, instead of generating a linear ramp voltage as in conventional ADCs, we generated a nonlinear ramp voltage by appropriately choosing different values of memristive conductances such that the shape of the ramp waveform matches that of the inverse of the desired NL activation function. Using this method, we demonstrate energy-efficient 5-bit implementations of commonly used NL functions such as sigmoid, hyperbolic tangent, softsign, softplus, elu, selu etc. A one-point calibration scheme is shown to reduce the integral nonlinearity (INL) from 0.948 to 0.886 LSB for various NL functions. Usage of the same IMC cells for ADC and dot-product also gives added robustness to read voltage variations, reducing INL to  LSB compared to  LSB for conventional methods. Using this approach combined with hardware aware training[41  ###reference_b41###], we experimentally demonstrate a keyword spotting (KWS) task on the Google speech commands dataset[42  ###reference_b42###]. With a  hidden neuron LSTM layer (having  nonlinear gating functions) that uses  memristors from the  memristor array on our chip, we achieve  accuracy using a 5-bit NL-ADC with a  and  improvement of area and energy efficiencies respectively at the system level for the LSTM layer over previous reports. Moreover, compared to a conventional approach using the exact same configuration (input and output bit-widths) as ours, the estimated area and energy efficiency advantages are still retained at  and  respectively for system level of evaluation. Finally, we demonstrate the scalability of our system by performing a character prediction task on the Penn Treebank dataset[43  ###reference_b43###] using a LSTM model X bigger than the one for KWS using experimentally validated nonideality models and achieving software equivalent accuracy. The improvements in area efficiency are estimated to be  over a conventional approach baseline and  over earlier work[32  ###reference_b32###] at the system level, with the drastic increase in performance due to the much higher number of nonlinear functions in the larger model."

This function is exactly the ramp function that needs to be generated during the conversion process, as described in detail in the earlier section. The figure shows the choice of  (x,y) tuples for -bit nonlinear conversion.\nThe voltage difference between successive points ( in Equation 3  ###reference_###) is shown in Fig. 2  ###reference_###d highlighting the unequal step sizes. Memristors proportional to these step values need to be programmed in order to generate the ramp voltage, as described next.\nWe show our proposed in-memory nonlinear ADC circuits in Fig. 2  ###reference_###b.\nIn each memory core, only a single column of memristors will be utilized to generate  with very low hardware cost as shown in Fig. 2  ###reference_###e.\nThe memory is separated into  columns for the multiplication-and-accumulation (MAC) part and one column for the nonlinear ADC (NL-ADC) part. For the MAC part, the inputs are quantized to -bit ( to  in experiments) if necessary and transferred into pulse width modulation (PWM) signals sent to the SL of the array.\nTo adapt to the positive and negative weights or inputs in the neural networks, we encode one weight or input into differential 1T1R pairs and inputs shown in Supplementary Fig. S9  ###reference_###.\nWe propose a charge-based approach for sensing the MAC results where the feedback capacitor of an integrator circuit is used to store the charge accumulated on the BL. Denoting the feedback capacitor by , the voltage on the sample and hold (S&H) for the k-th column is:\nwhere  is the clamping voltage on the bitline enforced by the integrator,  denotes the pulse width encoding the i-th input and  is the memristive conductance on the i-th row and k-th column.\nIn the column of the NL-ADC part, we have two sets of memristors. One is the memristors for generating the initial bias voltage ( in the earlier section), and another set of memristors is for generating the nonlinear ramp voltages.\nThe addition of bias memristors is used to set the initial ramp value as well as calibrate the result after programming the NL-ADC memristors due to programming not being accurate. The \u2018one point\u2019 calibration will move the ramp function generated by the NL-ADC column to intersect the desired, theoretical ramp function at the zero-point which leads to minimal error. This is described in detail in the next sub-section.\nAs shown in the timing diagram in Fig. 2  ###reference_###b, after the MAC results are latched on the S&H, the positive input with one cycle pulse width is first sent into NL-ADC column to generate a bias voltage (corresponding to the most negative voltage at the starting point ) for the ramp function on . Then for each clock cycle, negative input is sent to the SL of NL-ADC memristors to generate the ramp voltages on . Since the direction of each step voltage is known, only one memristor is used corresponding to the magnitude of the step while the polarity of the input sets the direction of the ramp voltage. Using less memristors for every step provides the flexibility to use more devices for calibration or error correction if stuck devices are found. The ramp voltage generated at the q-th clock cycle, , is given by the following equation:\nwhere  are the pulse width of ADC read pulses and  equals  from Equation 3  ###reference_###. An example of the temporal evolution of the ramp voltage is shown in the Supplementary Note S9.  ###reference_9### The comparison between the  and MAC result is done by enabling the comparator using the clk_ad signal after each step of the generation of ramp voltages.\nThe conversion continues for  cycles producing a thermometer code or pulse width proportional to the nonlinear activation applied to the MAC result. The pulse-width can be directly transferred to other layers as the input as done in other works[32  ###reference_b32###]; else, the thermometer code can be converted to binary code using a ripple counter[23  ###reference_b23###].\nTo prove the effectiveness of this approach, we simulate it at the circuit level and the results are shown in Fig. S2  ###reference_###. The fabricated chip does not include the integrators and the comparator which are implemented in software after obtaining the crossbar output. In-memory ramp ADC using SRAM has been demonstrated earlier[45  ###reference_b45###] in a different architecture with a much larger () overhead compared to the memory used for MAC operations; however, nonlinear functions have not been integrated with the ADC. Implementing the proposed scheme using SRAM would require many cells for each step due to the different step sizes. Since an SRAM cell can only generate two step sizes (+1 or -1) intrinsically, other step sizes need to be quantized and represented in terms of this unit step size (or LSB). Denoting this unit step by ,  is the number of SRAM cells needed for a single step while the total number of steps needed is given by . Fig. 2  ###reference_###e illustrates this for several common nonlinear functions.\nHowever, thanks to the analog tunability of the conductance of memristors, we can encode each step of the ramp function  into only one memristor  which leads to the usage of much lower number of bitcells (1.28X - 4.68X) compared with nonlinear SRAM-based ramp function generation (Fig. 2  ###reference_###e) for the 5-bit case. However, the write noise in memristors can result in higher approximation error than the SRAM version. Using Monte-Carlo simulations for the SRAM case, we estimate the mean squared error (MSE) for a memristive 5-bit version is generally in between that of the 5-bit and 4-bit SRAM versions (e.g. MSE for sigmoid nonlinearity is  and  respectively for the 5-bit and 4-bit SRAM versions, while that of the memristive 5-bit version is ). Hence, we also plot in Fig. 2  ###reference_###e the number of SRAM bitcells needed in 4-bit versions as well. However, combined with the inherently smaller () bitcell size of memristors compared to SRAM, our proposed approach still leads to more compact implementations with very little overhead due to the ramp generator. The approximation accuracy for the memristive implementation is expected to improve in future with better devices[46  ###reference_b46###] and programming methods[47  ###reference_b47###]. Details of the number of SRAM cells needed for six different nonlinear ramp functions are shown in Supplementary Tab. S2  ###reference_###. The topology shown here is restricted to handle inputs limited to the dimension of the crossbar. We show in Supplementary Note S10.  ###reference_10### how it can be extended to handle input vectors with dimensions larger than the number of rows in the crossbar by using the integrator to store partial sums and splitting the weight across multiple columns.\n###figure_2###"

To tackle these problems, we introduce the adaptive mapping method to calibrate the programming errors. For each nonlinear function, we first extract the steps  of the function as illustrated in Fig. 2  ###reference_###d. Then we normalize them and map them to the conductances with a maximum conductance of . Detailed characterization of our memristive devices were presented earlier[48  ###reference_b48###]. We program the conductances using the iterative-write-and-verify method explained in methods. However, the programming will introduce errors, and hence, we reuse the  (=5 in experiments) bias memristors to calibrate the programming error according to the mapped result. These memristors are also used to create the starting point of the ramp , which is negative in general (assuming domain of g() spans negative and positive values). Hence, positive voltage pulses are applied to these bias/calibration conductances while negative ones are applied to the  for the ramp voltage as shown in Fig. 2  ###reference_###(a). Based on this, the one-point calibration strategy is to match the zero crossing point of the implemented ramp voltage with the desired theoretical one by changing the value of  to . The total calibration conductance is first found as:\nHere,  is the index where the function  crosses the zero point of the x-axis. We then represent this calibration term using only a few memristors with the largest conductance on the chip (). The number of memristors used for calibration is  in which  memristors are  and the one left is . More details about the calibration process including timing diagrams are provided in the Supplementary Note S9.  ###reference_9###\nTo demonstrate the effectiveness of our approach, we experimentally programmed two frequently used nonlinear functions in neural network models: sigmoid function and tanh function, with the calibration methods mentioned above, as shown Fig. 3  ###reference_###a. We program  columns containing the same NL-ADC weights and calibration terms in one block of our memristor chip and set the read voltage to . In the left panel, we compare the transfer function with 3 different cases: (1) Ideal nonlinear function (2) Transfer function without on-chip calibration (3) Transfer function with on-chip calibration. We can find that the curve with calibration matches well with the ideal curve while the one without calibration has some deviation. We also show the programmed conductance map in the right panel for a block of  arbitrarily selected columns to showcase different types of programming errors that can be corrected. The first  rows are the NL-ADC weights representing 5-bit resolution. The remaining 5 rows are the calibration memristors after reading out the NL-ADC weights to mitigate the program error. In the conductance map on the right, we can also find some devices which are either stuck at OFF or have higher programming error. Fortunately,these errors happening during the NL-ADC weights programming can be compensated by the calibration part as evidenced in the reduced values of average INL. In addition to these two functions, we also show other nonlinear functions with in-memory NL-ADC in Supplementary Fig. S7  ###reference_### which covers nearly all activation functions used in neural networks. Further reductions in the INL may be achieved through redundancy. Briefly, the entire column used to generate the ramp has many unused memristors which may be used to program redundant copies of the activation function. The best out of these may be chosen to further reduce the effect of programming errors. Details of this method along with measured results from two examples of nonlinear activations are shown in Supplementary Note S11.  ###reference_11###.\nIn a real in-memory computing system, the voltage variations on-chip could harm the performance. This can be a challenge when using traditional ADC due to the lack of ability to track the voltage variation. For example, if the voltage we set for VMM is  but the actual voltage sent to SL is  (due to supply noise, voltage drop etc.), the final result read out from the ADC will deviate a lot from the real VMM result. Fortunately, our in-memory NL-ADC has the natural ability to track the voltage variations on-chip since the LSB of the ADC is generated using circuits matching those generating the MAC result. Hence, the read voltage is canceled out during the conversion and only the relative values of MAC and ADC conductances will affect the final result. To demonstrate that our proposed in-memory NL-ADC is robust under different read voltages, we run the experiment by setting different read voltages from  to  and measure the transfer function. From the result shown in Fig. 3  ###reference_###b, we can see that the conventional ADC has large variations (maximum INL of  LSB) due to  variations while our in-memory NL-ADC only experiences a little effect (maximum INL of  LSB).\n###figure_3###"

The KWS training network consists of Mel-frequency\ncepstral coefficient (MFCC), standardization, LSTM layer ( weight parameters in a  crossbar) and fully connected (FC) layer; detailed parameters pertaining to the task are provided in Methods. Further training with weight noise-aware and NL-ADC noise-aware (Methods) is implemented.\nOn-chip inference shown in Fig. 4  ###reference_###a is performed after training. After feature extraction (MFCC extraction and normalization), a single input audio signal is divided into  arrays, each with a feature length of . These extracted features, along with the previous 32-dimensional output vector  from the LSTM, are then sent to the memristor crossbar.

After adding the NL-ADC model to replace the nonlinear functions in the LSTM cell (Equation 4  ###reference_###), 91.1%, 90% and 89.4% inference accuracy were obtained in the 5-bit, 4-bit and 3-bit ADC models respectively which compare favorably with a floating-point baseline of 91.6%. To enhance the model\u2019s robustness against hardware non-ideal factors and minimize the decrease in inference accuracy from software to chip, we injected hardware noise (Methods) in the weight crossbar and NL-ADC crossbar conductances during the training process. The noise model data used in this process is obtained from the actual memristor crossbar and follows a normal distribution  N(0,) (Supplementary Fig. S8  ###reference_###c). As a result, we attain inference accuracies in software of 89.4%, 88.2%, and 87.1% for the 5-bit, 4-bit, and 3-bit NL-ADC cases models respectively. Note that the drop in accuracy is much less for feedforward models as shown in Supplementary Note S8.  ###reference_8### Further, the robustness of the classification was verified by conducting  runs; the small standard deviation shown in Fig. 4  ###reference_###d confirming the robustness. Through noise-aware training, we obtain weights that are robust against write noise inherent in programming memristor conductances. These weights are then mapped to corresponding conductance values through a scaling factor by matching the maximum weight after training to the maximum achievable conductance (Methods). Both the conductance values associated with the weights and the NL-ADC are programmed on the memristor crossbar, facilitating on-chip inference.\nFig. 4  ###reference_###c shows the performance of weight mapping after programming the memristor conductance using iterative methods. The error between the programmed conductance value and the theoretical value follows a normal distribution. The on-chip, experimentally measured inference accuracies achieved are 88.5%, 86.6%, and 85.2% for the 5-bit, 4-bit, and 3-bit ADC models, respectively where the redundancy techniques in Supplementary Note S11.  ###reference_11### were used for the 3-bit version. The experimental results indicate that 5-bit and 4-bit NL-ADC models can achieve higher inference accuracy than previous work[32  ###reference_b32###, 49  ###reference_b49###] (86.14% and 86.03%) based on same dataset and class number and are also within 2% of the software estimates, while that of the 3-bit version is marginally inferior. Nonetheless, it is important to highlight that the LSTM layer with the 3-bit ADC model significantly outperforms the 5-bit NL-ADC models in terms of area efficiency and energy efficiency as shown in Fig. 4  ###reference_###e ( 31.33TOPS/W, 60.09 TOPS/W and 114.40 TOPS/W for 5-bit, 4-bit, and 3-bit NL-ADC models, respectively). The detailed calculation to assess the performance of our chip under different bit precision is done following recent work[15  ###reference_b15###, 51  ###reference_b51###] and shown in Supplementary Tab. S5  ###reference_###. The earlier measurements were limited to the LSTM macro alone and did not consider the digital processor for pointwise multiplications (Eq. S3  ###reference_###) and the small FC layer. The whole system level efficiencies are estimated in detail in Supplementary Note S4.  ###reference_4###a for all three bit resolutions.\nTable 1  ###reference_### compares the performance of our LSTM implementation with other published work on LSTM showing advantages in terms of energy efficiency, throughput and area efficiency. For a fair comparison of area efficiencies, throughput and area are normalized to a 1 GHz clock and 16 nm process respectively. Fig. 4  ###reference_###e also graphically compares the energy efficiency and normalized area efficiency of the LSTM layer in our chip for KWS task with other published LSTM hardware. The results demonstrate that our chip with 5-bit NL-ADC exhibits significant advantages in terms of normalized area efficiency () and energy efficiency ( system level) compared to the closest reported works. It should be noted that comparing the raw throughput is less useful since it can be increased by increasing the number of cores. In order to dig deeper into the reason for the superiority of our chip compared to conventional linear ADC chips[52  ###reference_b52###, 53  ###reference_b53###], detailed comparisons with a controlled baseline were also done using two models as shown in Fig. S3  ###reference_### where  digital processor is assumed. While their inputs and outputs remain the same, the key distinction lies in the nonlinear operation component. Utilizing these two architectures, we conducted evaluations on the energy consumption and area of the respective chips (Tab. S10  ###reference_0### and Tab. S11  ###reference_1###) to find the proposed one has  and  better metrics at the system level respectively.\nFig. 4  ###reference_###f presents a comprehensive comparison of energy efficiency for its individual subsystems among this work (5-bit NL-ADC), the conventional ADC model, and a reference chip[32  ###reference_b32###] using IMC \u2013 the MAC array, NL-processing, and the full system comprising the MAC array, NL-processing, and other auxiliary circuits (Tab. S13  ###reference_3###). Our approach exhibits significant energy efficiency advantages, particularly in NL-processing, with a remarkable 3.6 TOPS/W compared to 0.3 TOPS/W and 0.9 TOPS/W for the other two chips. This substantial improvement in NL-processing energy efficiency is a crucial factor contributing to the superior energy efficiency of our chip, as depicted in Fig. 4  ###reference_###e.\nThe improvements in area efficiency also come about due to the improved throughput of the NL-processing. Fig. S4  ###reference_### shows the energy and area breakdown of the main chip components of this work (5-bit NL-ADC) and the conventional model (5-bit ADC). Our work demonstrates superior area efficiency, with a value of 130.82 TOPS/mm2, compared to the conventional ADC model\u2019s 9.56 TOPS/mm2 in Tab. S5  ###reference_###. This  improvement is attributed mostly to throughput improvement of  over the digital processor in conventional systems. Table 2  ###reference_### compares our proposed NL-ADC with other ADC used in IMC systems. While some works have used Flash ADCs that require single cycle per conversion, they have a higher level of multiplexing (denoted by # of columns per ADC) since these require exponentially more comparators than our proposed ramp ADC. Hence the effective AC latency in terms of number of clock cycles for our system is comparable with others. Moreover, since our proposed NL-ADC is the only one with integrated activation function (AF) computation, the latency in data conversion followed by AF computation (denoted by AF latency in the table) is significantly lower for our design. Here, we assume LUT based AF computation using  clocks and 1 digital processor per 1024 neurons like other work[23  ###reference_b23###]. Compared with other ramp converters, the area occupied by our 5-bit NL-ADC is merely 558.03 2 due to usage of only one row of memristors, while the traditional 5-bit Ramp-ADC[52  ###reference_b52###, 53  ###reference_b53###] together with nonlinear processor occupy an area of 4665.47 2. This substantial disparity in ADC area due to a capacitive DAC-based ramp generator[52  ###reference_b52###, 53  ###reference_b53###] leads to a further difference in the area efficiency of the two chips. Using oscillator-based ADCs[54  ###reference_b54###, 55  ###reference_b55###] instead of ramp-based ones will reduce the area of the ADC in traditional systems, but the throughput, area and energy-efficiency advantages of our proposed method will still remain significant. Also, note that due to the usage of memristors for reference generation, our system is robust to perturbations (such as changes in temperature or read voltage) similar to other designs using replica biasing[56  ###reference_b56###]. Lastly, for monotonic AF, our design can directly generate pulse width modulated (PWM) output (like other ramp based designs[32  ###reference_b32###]) which can be passed to the next stage avoiding the need for DAC circuits at the input of the next stage as well as counters in the ADC. This is known to further increase energy efficiencies[57  ###reference_b57###], an aspect we have not explored yet.\n###figure_4### 5 bit, 4 bit and 3 bit NL-ADC are calculated based on 16 nm CMOS technology and clock frequency of 1 GHz.

An architecture for further reduced crossbars of size  is shown in Supplementary Note S10.  ###reference_10### To assess the impact of on-chip buffers and interconnects in performing data transfer between tiles, Neurosim[65  ###reference_b65###] is used to perform system level simulations where the ADC in the tile is replaced by our model (details in Supplementary Note S4.  ###reference_4###(b)).\nFirst, the accuracy of the character prediction task is assessed using bits per character (BPC)[23  ###reference_b23###], which is a metric that measures the model\u2019s ability to predict samples from the true underlying probability distribution of the dataset, where lower values indicate better performance. Similar to the earlier KWS case, memristor write noise and NL-ADC quantization effects from the earlier hardware measurements are both included in the simulation. The results of inference are displayed in Fig. 5  ###reference_###c, with a software baseline of 1.334. BPC results of 1.345, 1.355, and 1.411 are obtained with the 5-bit, 4-bit, and 3-bit ADC models, respectively when considering perfect weights, and exhibits a drop of only  for the 5-bit NL-ADC model compared to the software baseline. Finally, the write noise of the memristors are included during both the training and testing phases using the same method as the KWS model resulting in BPC values of of 1.349, 1.367, and 1.428 are obtained with the 5-bit, 4-bit, and 3-bit NL-ADC models (with error bars showing standard deviations for  runs). Compared to other recent work[23  ###reference_b23###] on the same dataset that obtained a BPC of 1.358, our results are promising and show nonlinear function approximation by NL-ADC can be successfully applied to large-scale NLP models.\nThe throughput, area, and energy efficiencies are estimated next (details in Supplementary Note S3.  ###reference_3###, Sup. Tab S6  ###reference_### at the macro level and in Supplementary Note S4.  ###reference_4###(b) at the system level) and compared with a conventional architecture (Sup Tab.

These are compared along with current LSTM IC metrics in Fig. 5  ###reference_###d and Fig. 5  ###reference_###e. Considering the 5-bit NL-ADC, our estimated throughput and energy efficiency of  TOPS and  TOPS/W at the system level are  and  better for system level than earlier reported metrics[23  ###reference_b23###] of  TOPS and  TOPS/W respectively. Lastly, the normalized area efficiency of our NL-ADC based LSTM layer is  better at system level than earlier work[23  ###reference_b23###] (reporting results on same benchmark) due to the increased throughput and reduced area (we also estimated that an 8-bit version of our system will still be  more area efficient and  more energy efficient). Compared to the conventional IMC architecture baseline for this LSTM layer, we estimate an energy efficiency advantage of  at the system level similar to the KWS case, but the throughput and area efficiency advantages of  and  for system level respectively remain even for  digital processors.\n###figure_5###"

By predistorting the ramp waveform to follow the inverse of the desired nonlinear activation, our NL-ADC removes the need for any digital processor to implement nonlinear activations. The analog conductance states of the memristor enable the creation of different programmable voltage steps using a single device, resulting in great area savings over a similar SRAM-based implementation. Moreover, the in-memory ADC is shown to be more robust to voltage fluctuations compared to a conventional ADC with memristor crossbar based MAC. Using this approach, we implemented a LSTM network using 9216 weights programmed in the  memristor chip to solve a 12-class keyword spotting problem using the Google speech commands dataset. The results for the 5-bit ADC show better accuracy of  than previous hardware implementations[32  ###reference_b32###, 50  ###reference_b50###] with significant advantages in terms of normalized area efficiency () and energy efficiency () compared to previous LSTM circuits. We further tested the scalability of our system by simulating a much larger network (6,112,512 weights) for natural language processing using the experimentally validated models. Our network with 5-bit NL-ADC again achieves better performance in terms of BPC than recent reports[23  ###reference_b23###] of IMC based LSTM ICs while delivering  and  better area and energy efficiencies at the system level. Our work paves the way for very energy efficient in-memory nonlinear operations that can be used in a wide variety of applications."

Briefly, the column used to generate the ramp for the ADC consists of the same number of memristors as those used for MAC, i.e. 64. However, when we use only 32 out of these for a 5-bit NL ADC, the remaining memristors in the same column are unused. The number of unused memristors are even more for 4-bit and 3-bit versions of the NL-ADC. We propose to use them and program redundant copies of the ADC reference in the case of 3-bit and 4-bit ADCs. For the 5-bit ADC, the starting location (row address in that column) of the ramp can be varied as well as multiple programming attempts can be made to get the best NL-ADC characteristic. This requires minimal overhead of only an extra register of 6-bits to store the base or starting address of the ramp for every crossbar. Alternatively, additional columns may also be used for programming redundant copies of the NL-ADC\u2013this is the approach we have taken to get the new measured results below. For larger crossbars like 128x128, many such redundant copies can be fit into the same column with no extra overhead. We show an example where a 5-bit NL ADC for the GELU function is programmed by choosing the best out of 4 possible NL-ADC characteristics(Fig. S12  ###reference_2###). The average INL reduces to -0.38 LSB from -1.14 LSB proving the efficacy of this method.

However, the concept can still be applied by splitting the function into sub-parts where it is monotonic and using a logic to decide which sub-part has to be used. Therefore, we directly divide the original function by selecting the extrema (maxima or minima) as the key points and then obtain the conductance values for each sub-part following the earlier technique. Taking the Swish function[74  ###reference_b74###] (Fig. S13  ###reference_3###a) and 5-bit NL-ADC as an example, first the minima is identified as  and this is used to split the function into two parts\u2013the left and right of the minima. As before, starting from the minimum point  of the function, the range of the function is divided into 30 equal intervals (-). The spacing between two consecutive \u2018y\u2019 values is the resolution of the NL-ADC. For  and , each value corresponds to two x values ( and ,  and ), so 33 x values can be obtained. Using the formula , 32  can be obtained. Then, according to the formula , 32  values can be obtained as conductance to be programmed into 32 RRAM cells.\nAfter obtaining 32 conductance values, the other operations are the same as the previous monotonic function method. The control timing of the pulse is exactly the same as in Fig.S10  ###reference_0###. In this way, a ramp waveform starting from  and passing through , , \u2026,  can be generated as shown in Fig. S13  ###reference_3###c. The output result is still the thermometer code that generates positive and negative values by comparing the MAC value and the step wave of -. However, the output has to be obtained by two different equations depending on which sub-part has to be chosen corresponding to the input x. This can be done easily based on the output bits of the thermometer code. In the example shown, the minima is at ; hence, we have to use the left sub-part of the function if  and the right sub-part otherwise. Here,  denotes the k-th bit of the thermometer code produced by the sense amplifier (SA). In the case of monotonic functions, these bits of thermometer code can be converted to a binary code (representing the decimal number ) using a ripple counter (with bits denoted by ) that counts the number of 1\u2019s in the thermometer code. However, in this case of non-monotonic functions, two different equations have to be used for the two sub-parts to produce the final \u201cresult\". For the Swish and Gelu functions, it is given by:\nas also shown in Fig. S13  ###reference_3###a. In this case,  as seen in S13  ###reference_3###a.\nThe hardware circuit implementation for this is shown in Fig. S13  ###reference_3###b. The inputs to the comparator are the MAC values and the ramp waveform corresponding to - as earlier. Now, in addition we need a flip-flop to store  that determines which sub-part has to be selected as explained earlier. The output of this flip-flop controls two multiplexors (MUX) to create the final result according to equation S6  ###reference_###. If , the result is given by  represented by  in two\u2019s complement. On the other hand, if , the result is given by . We use two MUXs and one adder to implement this simple comparison and addition as shown in Fig. S13  ###reference_3###b. The mathematical relationship can be summarized as follows:\nFor example, when MAC value is ,  is equal to 2 as shown in the inserted table in Fig.S13  ###reference_3###a. In that case,  and we can get the two results from left MUX and right MUX: (i.e., ) and  respectively, obtaining the sum result of  equivalent to  in two\u2019s complement. Similarly, when MAC value is ,  is 5,  and we can get the two results from left MUX and right MUX: (i.e., ) and  respectively. Then the sum result is  as desired.\nTwo different commonly used non-monotonic activation functions of Gelu[75  ###reference_b75###] and Swish[74  ###reference_b74###] were programmed on the memristor array and the results are shown in S13  ###reference_3###d and S13  ###reference_3###e respectively. As done earlier in Fig. 3  ###reference_###,  copies of the same function were programmed to see the variability and the one point calibration was used to reduce average INL to  LSB for Gelu and  LSB for Swish respectively.\nWe reprogrammed the memristors for both Gelu and Swish taking more number of sample points corresponding to negative outputs ( Fig. S13  ###reference_3###f and Fig. S13  ###reference_3###g). This programmability is an advantage of our memristive ADC over other ones with fixed reference. Combined with the earlier described redundancy methods, the achieved average INL are -0.24 LSB and -0.13 LSB respectively.\nFinally, to assess whether our method of approximating the non-monotonic AF with uniform distribution of Y is effective in practical situations, two experiments are conducted using a Vision Transformer [76  ###reference_b76###] (26 layers with 86M parameters) with the Gelu function on the CIFAR-100 dataset and a mixed-depth convolutional network [77  ###reference_b77###] (124 layers with 2.6M parameters) with the Swish function on the CIFAR-10 dataset. Firstly, we train these two networks to obtain the software-level baseline accuracy: 92.2% and 93.7%. When implementing these models on hardware, the reference voltage range of ADC is limited, which leads to clipping in the MAC (Multiply-Accumulate) results. So the accuracy of Vision Transformer and mixed-depth convolutional network degrade to 91.4% and 93.2%. In this case, we modified the training method to be: quantized activation functions are employed for forward propagation, while unquantized activation functions are used for backward propagation. As a reference, ReLU functions are also used to check if the quantized non-monotonic AF have any advantage over simpler but high precision AF. The networks utilizing 5-bit Gelu and Swish achieve 91.3% and 93.2% accuracy, respectively. This represents a reduction of only 0.9% and 0.5% compared to the SW baseline, while also outperforming the use of ReLU in place of the non-monotonic functions (accuracy when using ReLU was 91% and 91.65% respectively for these datasets). These results prove that 5-bit approximations of the AF incur very low loss in accuracy even for complicated networks such as vision transformers."

To do this simulation, all the conductances in the KWS task are written as weighted average of the two nearest conductance values among the initial 16 reference conductances in this plot. For example, we can write for the k-th conductance,\nWhere , and  indicates the values of the p-th reference conductance at time t = 0.\nand  are weighting coefficients. Then, the value of  at time  is obtained by the same weighted average of the drifted values of these reference conductances at time  as follows: .\nUsing this method, we show that if the RRAM drift affects the NL-ADC alone, the drop in accuracy is negligible (<1%) for the 5-bit ADC (Fig. S15  ###reference_5###a). However, if the drift affects both the weights and the NL-ADC, then the drop in accuracy starts increasing to  6% for the 5-bit ADC after 500,000 seconds (Fig. S15  ###reference_5###b). In our work, we show that modifying the training by adding a larger amount of noise during training, the drop in accuracy can be restricted to <2% even at 500,000 seconds (Fig. S15  ###reference_5###c). This is much larger than the time needed for ADC operation during programming ( minutes) even when one single ADC is used for read operations during programming, as shown in Supplementary Note S5.  ###reference_5###. Hence, the programming can be finished much before conductance drift starts affecting results."

+            "text": "In our prototype system, the write operation of memristors is done by serially accessing one device at each time. Multiplexers at each row and column of the crossbar arrays are used to select one memristor device at each time. For the read process, a constant 0.2V voltage drop is applied on the memristor device. The current flowing through the device is collected by a transimpedance amplifier and converted to voltage signal, which is then digitized by a conventional ADC. For the writing process, a positive/negative voltage drop is applied on the memristor cell to SET/RESET the device. The pulse width of SET/RESET voltage is set to 20 ns. The amplitude of SET/RESET voltage and the voltage on the gate terminal of the transistor of the 1T1M cell (which is used for current compliance) are adaptively changed in the write-and-verify process. It is worth noting that the ADC/DAC needed in the read/write process can be shared across all the rows and columns of the array, causing very limited overhead. To accurately tune the conductance of the memristor to an arbitrary value, multiple iterations of write-and-verify might be needed, which consumes relatively long time (100 iterations is a conservative estimate [71  ###reference_b71###]). However, thanks to the non-volatile property of memristor devices, the conductance tuning is a one-time overhead and does not influence the inference latency and throughput. Once the weights of the neural network and references of the ADCs are programmed to the memristor array, they can be retained for any later usage without the need of programming the memristors again. Nevertheless, we assume usage of one ADC per crossbar array for better scalability in programming and have included its overhead (area of  [23  ###reference_b23###]) in area calculations at system level."

+    "abstract": "We present InfiniDreamer, a novel framework for arbitrarily long human motion generation. InfiniDreamer addresses the limitations of current motion generation methods, which are typically restricted to short sequences due to the lack of long motion training data. To achieve this, we first generate sub-motions corresponding to each textual description and then assemble them into a coarse, extended sequence using randomly initialized transition segments. We then introduce an optimization-based method called Segment Score Distillation (SSD) to refine the entire long motion sequence. SSD is designed to utilize an existing motion prior, which is trained only on short clips, in a training-free manner. Specifically, SSD iteratively refines overlapping short segments sampled from the coarsely extended long motion sequence, progressively aligning them with the pre-trained motion diffusion prior. This process ensures local coherence within each segment, while the refined transitions between segments maintain global consistency across the entire sequence. Extensive qualitative and quantitative experiments validate the superiority of our framework, showcasing its ability to generate coherent, contextually aware motion sequences of arbitrary length.",

It is a challenging task in computer vision, with great potential to benefit various downstream applications, such as AR/VR and film production. Benefiting from advancements in deep generative models [17  ###reference_b17###, 46  ###reference_b46###, 33  ###reference_b33###, 4  ###reference_b4###, 10  ###reference_b10###, 41  ###reference_b41###] and the availability of large text-to-motion datasets [36  ###reference_b36###, 30  ###reference_b30###, 38  ###reference_b38###, 12  ###reference_b12###, 13  ###reference_b13###], text-to-motion generation has seen significant progress. Recent approaches [49  ###reference_b49###, 58  ###reference_b58###, 6  ###reference_b6###, 57  ###reference_b57###, 20  ###reference_b20###, 14  ###reference_b14###, 1  ###reference_b1###, 59  ###reference_b59###, 56  ###reference_b56###, 9  ###reference_b9###, 35  ###reference_b35###] are capable of generating realistic and coherent short motion sequences, typically around 10 seconds in duration. However, in most real-world applications, such as long-duration animations in gaming [18  ###reference_b18###] and full-body motion capture [53  ###reference_b53###, 28  ###reference_b28###], much longer motion sequences, spanning minutes or even hours, are often required. This gap presents a significant barrier to the broader applicability of current methods and highlights the critical need for advancements in generating continuous long-duration motions.\nThe primary challenge in generating arbitrarily long-motion sequences lies in the limited availability of high-quality long-sequence data [25  ###reference_b25###, 15  ###reference_b15###, 38  ###reference_b38###, 26  ###reference_b26###, 39  ###reference_b39###]. Most existing datasets predominantly consist of short sequences annotated with single actions [12  ###reference_b12###, 38  ###reference_b38###] or simple textual descriptions [13  ###reference_b13###, 36  ###reference_b36###, 30  ###reference_b30###], lacking the temporal depth needed for continuous long-motion generation. To overcome these limitations, many previous works adopted auto-regressive models [2  ###reference_b2###, 23  ###reference_b23###, 26  ###reference_b26###, 39  ###reference_b39###], which generate motions step-by-step based on previously generated frames. However, this auto-regressive nature often leads to the accumulation of errors over time, resulting in issues such as motion drift, repetitive patterns, and discontinuities over long motion sequences. Alternatively, some works utilize the infilling capabilities of motion diffusion models [44  ###reference_b44###, 54  ###reference_b54###, 61  ###reference_b61###]. In these methods, motion segments are generated based on individual textual descriptions, and transitions between segments are filled in through in-painting. However, due to the strong modifications applied at the boundaries of each segment, this approach often leads to conflicts between adjacent motions, causing abrupt transitions, distortions in movement, or even overwriting of previously generated content.\nTo mitigate the issues, we turn to a smoother synthesis approach based on score distillation. Originally introduced by DreamFusion [37  ###reference_b37###], Score Distillation Sampling (SDS) [37  ###reference_b37###] enables the creation of 3D assets using only a pre-trained text-to-image diffusion model. Unlike traditional diffusion sampling methods, which can result in abrupt local modifications, SDS [37  ###reference_b37###] emphasizes a gradual and smooth distillation process that maintains coherence across different views. Extending this advantage to temporal generation opens new possibilities for producing coherent long-duration human motion.\nIn this paper, we propose InfiniDreamer, a novel framework for generating arbitrarily long motion sequences. By contextually fine-tuning each sub-motion and refining transition segments between sub-motions, InfiniDreamer can generate coherent long-sequence motion in a training-free manner. Specifically, we first generate each sub-motion conditioned on its corresponding textual prompt and then assemble them into a coarsely extended sequence using randomly initialized transition segments. Next, we utilize a sliding window approach to iteratively sample short overlapping sequence segments from the coarse long motion sequence. We then propose Segment Score Distillation (SSD), an optimization method that refines each short sequence segment by aligning it with the pre-trained motion prior. This segment-wise optimization ensures the local coherence of each sampled segment, while the refined transition segments maintain global consistency across the entire long motion sequence. After multiple rounds of optimization, our framework eventually yields coherent, contextually-aware long motion sequences. To verify the effectiveness of our framework, we evaluated the motion sequence and transition segments on two commonly used datasets, HumanML3D [13  ###reference_b13###] and BABEL [38  ###reference_b38###]. The experimental results show that our method is significantly better than the previous training-free method. We also demonstrate our framework qualitatively, and the results show that our method has great contextual understanding capabilities, enable a seamless, coherent synthesis of long-duration motion sequences.\nOverall, our contributions can be summarized as follows:\n(1) We introduce InfiniDreamer, a novel framework capable of generating arbitrarily long human motion sequences in a training-free manner.\n(2) We propose Segment Score Distillation (SSD), which iteratively refines overlapping short segments sampled from the coarse long motion. This process aligns each segment with the pre-trained motion prior, ensuring local and global consistency across the entire motion sequence.\n(3) We conduct qualitative and quantitative evaluations of our framework. Experimental results show that our framework brings consistent improvement over the previous training-free methods."

Current works can be categorized into two main types: (i) GPT-based model and (ii) Diffusion-based Model. The former includes notable work such as T2M-GPT [57  ###reference_b57###], which combines VQ-VAE [50  ###reference_b50###] with a transformer architecture for human motion generation from text, achieving impressive results. MotionGPT [20  ###reference_b20###] treats human motion as a foreign language and trains on a mixed motion-language dataset to build a unified motion-language model. MoMask [14  ###reference_b14###] proposes a masked transformer framework with residual transformer, enhancing text-to-motion generation. On the other hand, diffusion-based models are first introduced by MotionDiffuse [58  ###reference_b58###] and MDM [49  ###reference_b49###]. They developed a transformer-based diffusion model for generating motion based on text input. Rather than directly mapping raw motion data to text, MLD [6  ###reference_b6###] encodes motion into a latent space, improving the model\u2019s efficiency. Recently, Motion Mamba [64  ###reference_b64###] combines state-space models (SSMs) [11  ###reference_b11###] with diffusion models, offering an efficient framework for text-to-motion generation. All of these methods are capable of generating realistic and coherent human motion sequences, yet producing arbitrarily long human motion remains a challenge.\n###figure_1###"

However, these models suffer from error accumulation over time, causing issues like motion drift, repetitive patterns, and even \u2019freezing\u2019 after several iterations. To overcome this limitation, PCMDM [54  ###reference_b54###] introduces a past-conditioned diffusion model alongside a coherent sampling strategy for long human motion generation. PriorMDM [44  ###reference_b44###] proposes an innovative sequential composition approach, which generates extended motion by composing prompted intervals and their transitions.

The first stage in our framework is the initialization of the long motion sequence, serving as a foundational structure for further optimization. To create this initial sequence, we start by randomly initializing the entire long motion sequence , which provides a rough, unsmoothed outline of the target motion. Then, we employ a pre-trained Motion Diffusion Model (MDM) [49  ###reference_b49###] with DDIM sampling [46  ###reference_b46###] to generate each motion segment  within the sequence. Each segment  is conditioned on the respective text prompt , ensuring that the generated motion aligns semantically with the desired motion described in the prompt.\nMotion Segment Sampling Module. With the initialized sequence in place, we proceed to sample specific motion segments, which are essential for guiding the iterative optimization in subsequent steps. To achieve this, we employ a sliding window of size , which moves along the long motion sequence with a stride size . This sliding window technique allows us to iteratively sample overlapping short motion segments from the long sequence, denoted as . By maintaining overlap between adjacent segments, the sliding window preserves continuity and smoothness between them, thereby enhancing the temporal coherence of the generated long motion sequence.\nSegment Score Distillation. This module leverages a pre-trained motion diffusion model  to optimize the distribution of the sampled short sequences, ensuring that each segment aligns with the underlying diffusion sample distribution. Specifically, Segment Score Distillation (SSD) iteratively optimizes each short motion segment to bring it closer to the high-quality distribution learned by the diffusion model, thereby enhancing the coherence and quality of the overall long motion sequence. To achieve this, for each sampled short motion segment , we first randomly sample a timestep , then obtain each noised segment  through , where  and  are noise scheduling parameters, and  represents Gaussian noise.\nUsing the motion diffusion model in an unconditional setting, we then incorporate an alignment loss to align the sampled motion segment with the predicted signal :\nwhere  is weighting function. To further improve the coherence and realism of generated motions, we augment our method with three commonly used geometric losses, inspired by prior work [34  ###reference_b34###, 45  ###reference_b45###, 49  ###reference_b49###]. These include (1) positional constraints when predicting rotations, (2) foot contact constraints to maintain stable ground interaction, and (3) velocity regularization to encourage smooth transitions:\nwhere  is the forward kinematic function, it maps joint rotations to joint positions (or acts as the identity function if joint rotations are not predicted).  is the binary foot contact mask for each frame , it denotes whether the foot touches the ground, helping mitigate foot-sliding by nullifying ground-contact velocities. Together, our final Segment Score Distillation loss is:\nwhere ,  and  are hyper-parameters that balance the contribution of each geometric loss in the overall objective function. We set them to  in our experiments on the HumanML3D dataset and set them to  for the BABEL dataset. We summarize our proposed SSD in Algorithm 1  ###reference_###."

We observe that with a very small , the performance of transition segments declines sharply. However, as  increases, the transition quality exhibits fluctuating declines. This suggests that a moderate context length is beneficial for transition generation, whereas an overly extended context introduces interference. In terms of motion segment generation, performance consistently decreases as  grows. We speculate this is due both to MDM\u2019s limitations in handling long sequences and to the interference in semantic alignment caused by excessive context length.\nAblation on Stride Size . In Tab. 3  ###reference_###, we also examine the impact of the hyper-parameter Stride Size  on model performance.  controls the frame shift of the sliding window in each step and, consequently, the overlap between segments. Our experiments show that when , this parameter has minimal impact on performance. However, when , there is a noticeable improvement in motion generation, whereas transition generation performance drops sharply.\nThe improvement in motion generation can be attributed to the nature of SSD, which adds noise during optimization. This noise slightly degrades motion quality. When , certain motion frames are excluded from sampling and thus bypass SSD optimization, resulting in performance gains. In contrast, since transitions are initialized randomly, excluding certain transition frames from optimization effectively leaves them as random noise, which severely impacts transition quality.\nAblation on Learning Rate . The learning rate  controls the update magnitude for long motion sequence parameters. In Fig. 4  ###reference_###, we illustrate the effect of different learning rates on motion sequence generation. We observe that an excessively high learning rate will cause the motion amplitude to gradually decrease, eventually resulting in a static output, leading to motion loss. As shown in the top row of Fig. 4  ###reference_###, where a kicking motion is optimized into stillness. Conversely, a lower learning rate leads to under-training, introducing more noise and causing motion distortions. As shown in the bottom of Fig. 4  ###reference_###, we notice significant motion distortion and exaggerated amplitude in the transitional phase preceding the kick motion, highlighting the need for a balanced learning rate."

InfiniDreamer treats the long motion sequence as the differentiable parameters, and optimizes them using our proposed Segment Score Distillation (SSD), a method that employs pre-trained motion diffusion prior to optimize the short motion segment. Specifically, we iteratively sample short motion segments from the random initialized long-sequence motion. By continuously optimizing each sampled short motion segment from the long-sequence motion, we align each segment with the distribution of a pre-trained motion diffusion prior. This iterative process ultimately yields a coherent long-sequence motion. Note that our approach is independent of any specific motion diffusion prior. In other words, the generation of short motion clips and the ensemble of long motion sequences are decoupled. Therefore, future advancements in diffusion priors for short motion clip generation could further enhance the performance of our method. We hope our approach offers a new direction for addressing challenges in long-sequence generation."

We follow the evaluation protocol of FlowMDM [3  ###reference_b3###]. However, we only use FlowMDM [3  ###reference_b3###] to generate individual motion segments, and then use our method to generate the entire long motion sequence. As shown in Tab. 4  ###reference_### and Tab. 5  ###reference_###, we find that InfiniDreamer performs slightly worse than FlowMDM [3  ###reference_b3###] but outperforms previous training-free methods. We speculate that this is because FlowMDM [3  ###reference_b3###] is fine-tuned on long human motion sequences using both absolute and relative positional encodings, which introduces some interference in individual short motion segments. Our method, which adds further interference, therefore achieves slightly lower performance compared to FlowMDM [3  ###reference_b3###]. Nonetheless, the experimental results demonstrate the advantages of our approach over DoubleTake [44  ###reference_b44###].\n###figure_4### ###figure_5### We also conducted qualitative experiments to compare the results of our framework with those of FlowMDM [3  ###reference_b3###]. In this section, we use the open-source model of FlowMDM [3  ###reference_b3###] to generate its results, while for our method, we use MDM [49  ###reference_b49###] as our motion prior. As shown in Fig. 5  ###reference_###, we present two examples of long motion sequence generation. The first example, at the top of the figure, is generated using the text prompts \u2018jogging forward slowly\u2019 + \u2018a person is walking down the stairs\u2019 + \u2018jogging forward slowly\u2019. The results show that both FlowMDM and our method can infer the transitional \u2018walking up the stairs\u2019 segment before descending. However, FlowMDM exhibits slight motion drift during this segment. In the second example, with the text prompts \u2018a person is walking straight\u2019 + \u2018side steps\u2019 + \u2018he is walking backward\u2019, we observe that FlowMDM generates the \u2018side steps\u2019 motion incorrectly and also shows motion drift at the end. In contrast, our method avoids these issues, producing more accurate and coherent results. Additionally, we observe that the motions generated by FlowMDM exhibit a larger displacement range, while our method produces smoother and more controlled movements.\nIn this section, we present additional ablation studies. We explore the use of different text conditions to guide the optimization of Segment Score Distillation (SSD). In the original experiments, we optimized in an unconditional manner. Here, we use text prompts such as \u201ctransition\u201d and \u201cmotion\u201d as conditions, with a guidance scale of  applied during optimization. We conduct our ablation studies on the HumanML3D [13  ###reference_b13###] dataset. As shown in Tab. 6  ###reference_###, we observe that incorporating text prompts negatively affects the performance of InfiniDreamer. Using \u2018transition\u2019 as a prompt leads to a slight performance decline, while \u2018motion\u2019 causes a more significant drop. We believe this is because the chosen text prompts are struggle to capture the semantic diversity of various transition segments. Therefore, we opted for an unconditional model in our baseline.\nOur framework has an additional capability: it can generate long motion sequences from a single text prompt. It is a feature that currently beyond the reach of other models. Specifically, given a short-sequence generation model, Motion Diffusion Model (MDM) [49  ###reference_b49###], we set the total frame count of the long sequence to 520 frames and the frame count of each short sequence to 120 frames. We employ conditional Segment Score Distillation (SSD), using the text prompt as the conditioning input. At the beginning, we randomly initialize a long motion sequence. In this experiment, we omit the first stage of InfiniDreamer, meaning that we do not use MDM to generate the initial short motion sequence. In the subsequent stages, we set the guidance scale to  and the learning rate to . As shown in Fig. 6  ###reference_###, we use \u201ca person takes 3 steps backward\u201d as our textual prompt. InfiniDreamer, through conditional optimization, extends the generation capability of the original Motion Diffusion Model (MDM) from 70-200 frames to 520 frames, while maintaining alignment between the generated motions and the input text."

In the future, we plan to improve its efficiency and enhance InfiniDreamer\u2019s performance by advancing the capabilities of the short-sequence generation model."

When using \u2018transition\u2019 as the text prompt, the model performance slightly decreases, and when using \u2018motion\u2019 as the text prompt, the performance drops significantly. We believe this is because the text prompts used are not well-suited to capture the semantics of diverse transition segments.

Given a list of text prompts, our framework generates a coherent and continuous long-sequence motion that aligns closely with each prompt. To achieve this, we start by initializing a long motion sequence using the (1) Motion Sequence Initialization module. Next, the (2) Motion Segment Sampling module iteratively samples short, overlapping sequence segments from the initialized motion. Finally, we refine each sampled segment with our proposed (3) Segment Score Distillation, optimizing each segment to align with the prior distribution of the pre-trained motion diffusion model. Through this iterative process, the framework synthesizes a seamless and fluid long-duration motion sequence, with realistic motions matching each prompt and smooth transitions connecting them.",

+    "abstract": "Federated Learning (FL) has emerged as a promising method to collaboratively learn from decentralized and heterogeneous data available at different clients without the requirement of data ever leaving the clients. Recent works on FL have advocated taking a Bayesian approach to FL as it offers a principled way to account for the model and predictive uncertainty by learning a posterior distribution for the client and/or server models. Moreover, Bayesian FL also naturally enables personalization in FL to handle data heterogeneity across the different clients by having each client learn its own distinct personalized model. In particular, the hierarchical Bayesian approach enables all the clients to learn their personalized models while also taking into account the commonalities via a prior distribution provided by the server. However, despite their promise, Bayesian approaches for FL can be computationally expensive and can have high communication costs as well because of the requirement of computing and sending the posterior distributions. We present a novel Bayesian FL method using an efficient second-order optimization approach, with a computational cost that is similar to first-order optimization methods like Adam, but also provides the various benefits of the Bayesian approach for FL (e.g., uncertainty, personalization), while also being significantly more efficient and accurate than SOTA Bayesian FL methods (both for standard as well as personalized FL settings). Our method achieves improved predictive accuracies as well as better uncertainty estimates as compared to the baselines which include both optimization based as well as Bayesian FL methods.",

It involves multiple client-server communication rounds, where in each round the selected clients send their local models (trained on their private dataset) to the server and the server aggregates the received models followed by its broadcasting to all clients. Thus, the global model, an approximation to the model obtained if all the data was accessible, depends significantly both on the quality of the received clients\u2019 models and the chosen aggregation strategy at the server. As a result, a straightforward approach like FedAvg[1  ###reference_b1###] can yield a high-performing global model if the data is i.i.d. distributed among clients; however performs suboptimally in case of non i.i.d. data distribution. Moreover, the challenges are compounded if each client has a limited private dataset.\nThe limitations of standard FL become even more apparent with data heterogeneity, where clients have distinct data distributions. A single global model might fail to represent all clients well, leading to poor performance. This motivates personalized FL (pFL) [2  ###reference_b2###], which aims to adopt models to individual clients while leveraging shared global knowledge.\nIn such settings, learning the posterior distribution instead of a point estimate at each client results in enhanced performance and uncertainty measures, as demonstrated in several recent works, such as [3  ###reference_b3###, 4  ###reference_b4###, 5  ###reference_b5###, 6  ###reference_b6###] which have advocated taking a Bayesian approach to FL. Moreover, Bayesian FL is also natural for personalization because the server model can serve as a prior distribution in a hierarchical Bayesian framework, enabling easy personalization of client models using their respective client-specific likelihoods.\nHowever, existing Bayesian FL and pFL methods usually rely on running computationally expensive routines on the clients (e.g., requiring expensive MCMC sampling [3  ###reference_b3###], expensive Laplace\u2019s approximation which requires Hessian computations [4  ###reference_b4###] on the clients, or methods based on learning deep ensembles [7  ###reference_b7###]), as well as expensive client-server communication [8  ###reference_b8###] and aggregation at the server (note that, unlike standard FL, Bayesian FL would require sending the whole client posterior to the server). Due to such computational bottlenecks and communication overhead, Bayesian approaches lack scalability, especially for clients with limited resources and bandwidth.\n###figure_1### Thus,\nto bridge this gap, we propose a novel Bayesian FL algorithm FedIvon (with its high-level idea illustrated in Fig. 1  ###reference_###), that balances the benefits of Bayesian inference - enhanced performance, and quantification of predictive uncertainty - with minimal increase in computational and communication overhead.\nIn particular, we leverage the IVON (Improved Variational Online Newton) algorithm [9  ###reference_b9###] to perform highly efficient variational inference (VI) on each client by approximating its local posterior using a Gaussian with diagonal covariance. It uses the natural gradient to capture the geometry of the loss function for faster convergence. Moreover, it computes the Hessian implicitly, making our method computationally cheaper than other existing Bayesian FL and pFL methods that use explicit Hessian computation, e.g., Laplace\u2019s approximation [4  ###reference_b4###], expensive MCMC sampling [3  ###reference_b3###, 5  ###reference_b5###], or even VI [8  ###reference_b8###] at the clients. These local posteriors can be efficiently sent to the server and the global posterior can be computed for which we also present local posterior aggregation strategies.\nOur main contributions are:\nWe introduce a Bayesian FL method FedIvon that uses an efficient second-order optimization approach for variational inference, maintaining computational costs similar to first-order methods like Adam.\nOur method demonstrates improvements in predictive accuracy and uncertainty estimation compared to state-of-the-art (SOTA) Bayesian and non-Bayesian FL methods.\nOur method also supports client-level model personalization naturally by leveraging a hierarchical Bayesian framework. Clients can use the server\u2019s posterior as priors to learn their private models, effectively balancing local adaptation with global knowledge sharing."

+            "text": "FedAvg [1  ###reference_b1###], the foundational federated learning algorithm, approximates the global model as the weighted aggregation of locally trained client models, performing effectively with i.i.d. data distributions. Since then, numerous sophisticated and efficient algorithms have been proposed to handle more realistic challenges such as non-i.i.d. data distribution, heterogeneous and resource-constrained clients, and multi-modal data as explored in recent survey works [10  ###reference_b10###, 11  ###reference_b11###, 12  ###reference_b12###, 13  ###reference_b13###, 14  ###reference_b14###]. However, here, we will restrict our discussion to Bayesian FL and personalized FL algorithms as they are most relevant to our work.\nBayesian Federated Learning A key limitation of point-estimate-based approaches is their susceptibility to overfitting in limited data settings and lack of predictive uncertainty estimates. To address this, Bayesian approaches have been advocated for federated learning, which involves the computation of clients\u2019 local posterior distribution followed by their aggregation at the server to compute the global posterior distribution, offering enhanced performance and quantification of predictive uncertainty. Unfortunately computing full posterior distribution is intractable and poses communication overhead. FedBE [15  ###reference_b15###] mitigates the communication overhead by leveraging SWAG [16  ###reference_b16###] to learn each client\u2019s posterior but communicating only its mean. The server then fits a Gaussian/Dirichlet distribution to the clients\u2019 posterior mean and distills it into a single model to be communicated in the next round. However, FedBE does not incorporate clients\u2019 covariances, omitting the underlying uncertainty in their models during aggregation. FedPA [3  ###reference_b3###] addresses this by learning a Gaussian distribution for each client and computes the mean of the global posterior at the server. However, it eventually discards the covariance of the global posterior and computes a point estimate to limit the communication costs. Similarly, FedLaplace [4  ###reference_b4###] approximates each client\u2019s posterior as a Gaussian distribution, modeling the global posterior as a mixture of Gaussian, though eventually it too simplifies it to a single Gaussian by minimizing KL divergence.\nSecond-order Optimization for Federated Learning shows promise for improving convergence but is often limited by efficiency and communication overhead. Methods such as FedNL [17  ###reference_b17###], which use privacy-preserving Hessian learning and compression, and second-order approaches incorporating global line search [18  ###reference_b18###], offer potential solutions to these challenges.\nPersonalized Federated Learning In the case of non-iid data distribution among clients, a single global model represents the average data distribution and diverges substantially from each client\u2019s local distribution. Consequently, the global model, though benefitted from collaborative learning, performs suboptimally for individual clients. Personalized federated learning addresses this challenge by adapting a part or the whole model to the local data distribution explicitly. A typical approach is to split the model into two parts - a base model for global representation learning and a head model for personalized learning. FedPer [19  ###reference_b19###] and FedRep [20  ###reference_b20###] use this strategy, applying FedAvg for collaborative learning of the base model leveraged by the head for local data adaptation. Similarly, FedLG [21  ###reference_b21###] splits the model into local and global components to learn local and shared representations respectively. It shares the global parameters with the server while enhancing local parameters further using the unsupervised or self-supervised approach. PerFedAvg [22  ###reference_b22###] applies a Model-Agnostic Meta-Learning (MAML) [23  ###reference_b23###] inspired framework to learn a shared model for faster adaptation to the client\u2019s data. pFedME [24  ###reference_b24###] decouples personalized adaptation from shared learning by regularizing each client\u2019s loss function using Moreau envelopes. pFedBayes [25  ###reference_b25###] is a Bayesian approach that aims at learning the personalized posterior distribution of each client. In each round, pFedBayes computes clients\u2019 posterior using the global model as the prior and sends it to the server for updating the global model. pFedVEM [26  ###reference_b26###] also computes the client\u2019s posterior by restricting it to the Gaussian family. However, it leverages the collaborative knowledge of other clients by assuming conditional independence among clients\u2019 models given the global model."

This experimental setup poses significant challenges for training a robust global server model, as the limited and biased data from individual clients must be aggregated effectively to learn a model capable of generalizing across all classes. This scenario highlights the complexities and practical relevance of federated learning in real-world applications.\n###figure_16### ###figure_17### ###figure_18###"

+    "abstract": "Large vision-language models (LVLMs) have demonstrated exceptional performance on complex multimodal tasks. However, they continue to suffer from significant hallucination issues, including object, attribute, and relational hallucinations. To accurately detect these hallucinations, we investigated the variations in cross-modal attention patterns between hallucination and non-hallucination states. Leveraging these distinctions, we developed a lightweight detector capable of identifying hallucinations. Our proposed method, Detecting Hallucinations by Cross-modal Attention Patterns (DHCP), is straightforward and does not require additional LVLM training or extra LVLM inference steps. Experimental results show that DHCP achieves remarkable performance in hallucination detection. By offering novel insights into the identification and analysis of hallucinations in LVLMs, DHCP contributes to advancing the reliability and trustworthiness of these models.",

+            "text": "Leveraging the capabilities of large language models (LLMs) such as Vicuna [8  ###reference_b8###], OPT [39  ###reference_b39###], FlanT5 [9  ###reference_b9###], and LLaMA [33  ###reference_b33###], a prominent class of large vision-language models (LVLMs) has emerged, enabling the handling of vision-language tasks by incorporating aligned visual tokens as inputs to the LLM. Notable examples of these LVLMs include BLIP-2 [21  ###reference_b21###], InstructBLIP [10  ###reference_b10###], MiniGPT-4 [41  ###reference_b41###], and LLaVA [26  ###reference_b26###]. Although these models have achieved impressive performance, they continue to grapple with a critical challenge: hallucinations.\n###figure_1### ###figure_2### ###figure_3### Current approaches for assessing hallucinations in LVLMs can be broadly categorized into discriminative and generative methods. Discriminative approaches [22  ###reference_b22###, 27  ###reference_b27###, 15  ###reference_b15###] represented by POPE transform objects, attributes, or relationships into yes/no questions, e.g., \u201cIs there a/an {object}?\u201d. Then, they evaluate the hallucination severity based on the LVLM\u2019s responses. On the other hand, generative approaches [14  ###reference_b14###, 24  ###reference_b24###, 19  ###reference_b19###, 35  ###reference_b35###, 32  ###reference_b32###, 34  ###reference_b34###] represented by AMBER evaluate hallucinations by analyzing performance on generative tasks.\nAs we delve deeper into the reasons for hallucinations in LVLMs, one possibility is that they are due to the LLM\u2019s erroneous focus on the image, such as mistakenly believing a certain object is present when it is not. Therefore, we define the cross-modal attention as the attention to the visual token when the LLM generates the first token, effectively capturing multimodal interactions in LVLMs. We conjecture that when the model is in a hallucination state, it may exhibit a distinct attention pattern to the visual tokens, which may differ from that of non-hallucinating states, thus enabling the detection of model hallucinations.\nOur objective is to detect hallucinations by leveraging cross-modal attention patterns through our proposed DHCP method, as illustrated in Fig. 1(c)  ###reference_sf3###. Without DHCP, LVLMs are prone to hallucinations, such as providing incorrect answers in discriminative tasks Fig. 1(a)  ###reference_sf1### or generating content that is incongruent with the input image in generative tasks Fig. 1(b)  ###reference_sf2###. When DHCP is applied during LVLM inference, it monitors cross-modal attention with extreme light computational overhead to determine whether the model is in a hallucinatory or non-hallucinatory state, and then issues warnings for potentially hallucinatory outputs or blocks them entirely. DHCP is a lightweight and easy-to-deploy hallucination detection method that neither requires additional training of the LVLM nor incurs extra LVLM inference steps, while still delivering impressively strong performance in hallucination detection.\nWe found that the majority of DHCP false alarms corresponded to instances where the model exhibited uncertainty regarding the answer, occasionally bordering on random guessing. These cases warrant further investigation to enhance the trustworthiness of LVLM. This finding further suggests that the true effectiveness of DHCP may be greater than what is reflected by conventional evaluation metrics, as these metrics may not fully capture instances where the model\u2019s uncertainty is misinterpreted as a false alarm. Additionally, we investigate the application of DHCP for categorizing various sources of hallucinations, aiming to better understand the underlying factors contributing to different types of hallucinations in LVLMs.\nOur primary focus was on the discriminative task, where we conducted extensive experiments across multiple datasets and LVLMs to rigorously validate the effectiveness of DHCP. Additionally, we have conducted preliminary investigations into generative tasks and hallucination mitigation tasks. The promising results from these initial explorations suggest that our approach holds potential for success in these areas as well.\nOur main contributions are summarized as follows: (1) We are the first to identify significant differences in cross-modal attention patterns between hallucination and non-hallucination samples. (2) We introduce DHCP, a novel, simple, effective and efficient method for distinguishing hallucination samples from non-hallucination ones based on cross-modal attention patterns. (3) Extensive experimental results demonstrate that DHCP consistently delivers strong performance in hallucination detection across both discriminative and generative hallucination evaluation tasks."

The visual encoders typically use CLIP [29  ###reference_b29###, 11  ###reference_b11###], which encodes input images as visual features. The vision-language alignment module aligns visual features to the input space of the large language model, enabling the LLM to process information from the visual modality. Typical vision-language alignment modules include cross-attention [2  ###reference_b2###], linear layers or multi-layer perceptrons (MLPs) [26  ###reference_b26###, 25  ###reference_b25###, 5  ###reference_b5###], adapters [13  ###reference_b13###], and Q-former [41  ###reference_b41###, 21  ###reference_b21###, 10  ###reference_b10###]. Large language models can be selected from pre-trained LLMs, such as [33  ###reference_b33###] and [8  ###reference_b8###].

By analyzing the LLM\u2019s attention to visual tokens during the decoding of the initial output, we can effectively distinguish between hallucination and non-hallucination samples."

POPE [22  ###reference_b22###] is a classical LVLM object hallucination dataset that contains three clusters: random, popular, and adversarial. In all three clusters, the positive example questions select three objects already present in the image. The negative example questions differ in their choices: (a) \u201crandom\u201d selects three random objects that do not exist in the image, (b) \u201cpopular\u201d selects three objects that do not exist in the image but have the most occurrences in the dataset, and (c) \u201cadversarial\u201d selects three objects that do not exist in the image but have the most co-occurrences with objects that do exist in the image. The official POPE contains 500 images per cluster, with 3 positive and 3 negative examples per image, i.e., a total of 3000 questions per cluster. We denote the official POPE dataset as POPE.\nPOPE-Extended. We generated a larger dataset, POPE-Extended, using the same methods as POPE, with each cluster containing 22,670 images. The details of the generation process are provided in Sec. 7  ###reference_### of the Appendix. We divided POPE-Extended into training and test sets with an 8:2 ratio, ensuring that all POPE images are included in the test set.\nIntuitive Explorations on Cross-modal Attention. We fed images from the -popular set into the InstructBLIP Vicuna-7B and categorized them into four groups based on whether or not they hallucinated and whether they answered \u201cyes\u201d or \u201cno\u201d, i.e., hallucinated answered yes , hallucinated answered no , answered yes without hallucination , and answered no without hallucination . Their cross-modal attention maps are shown in Fig. 2  ###reference_###. For the four categories, with counts of 43,581, 49,605, 4,803, and 10,827, we randomly selected 4,000 examples from each category for display. Each row in the figure represents an image-question pair, and each column represents a visual token. We randomly selected a layer of the LLM and took the maximum value for the multi-head attention dimension. By examining Fig. 2  ###reference_###, we can draw the following two conclusions:\n(1) There is a significant difference in cross-modal attention between hallucination and non-hallucination samples for the same responses. For example, in samples that answered \u201cyes\u201d, the attention value of the 27th token when hallucination occurred (Fig. 2(b)  ###reference_sf2###) was significantly higher than when no hallucination occurred (Fig. 2(a)  ###reference_sf1###). Similar differences were observed in other layers of LLM.\n(2) There is a significant difference in cross-modal attention between different types of hallucinations. Comparing Figs. 2(b)  ###reference_sf2### and 2(c)  ###reference_sf3###, hallucination samples answering \u201cyes\u201d were LVLMs incorrectly perceiving the presence of objects that were not in the images, whereas hallucination samples answering \u201cno\u201d were LVLMs failing to recognize objects that were present in the images. The significant differences in the cross-modal attention of the two types of hallucinations suggest that different hallucinations may have different origins and mechanisms of occurrence.\n###figure_7### ###figure_8###"

Specifically, we aggregated all the image-question pairs in the three datasets -popular, -random, and -adversarial into the training set. Due to the unbalanced number of instances in the four categories, we set the sampling weight for each category to be the inverse of the number of instances in that category, to balance the data during the training process. For simplification, we purposely adopt a lightweight three-layer multilayer perceptron (MLP) as the detector, where the first layer flattens and transforms the attention map from (32, 32, 32) to 512, the second layer to 128, and the third layer to 4.

However, after the first-stage detection, the ratio of hallucination to non-hallucination samples becomes nearly 1:1 in both  and  categories, which provides an optimal condition for training a more refined second-stage detector focusing on finer-grained hallucination features.\nTo mitigate the high false alarm rate of the first-stage detector on hallucination categories in Tab. 1  ###reference_###, We extracted the correct and incorrect samples from those detected by the first-stage detector as hallucinations and trained two additional detectors for finer detection.\nOur second-stage training pipeline is shown in Fig. 3(b)  ###reference_sf2###.

For the discriminative Yes/No questions, the LVLM model has a 50% probability of randomly and luckily guessing the correct \u201cyes\u201d or \u201cno\u201d as the answer even in the hallucination state. Answering correctly does not necessarily mean that the LVLM actually understood the question and answered it without hallucination. We find that the samples for which our detector \u201cfalsely\u201d alarms as hallucinations are more likely to be samples that happened to guess correctly, which are also risky.\nTo verify this, we use the absolute value of the difference between the probabilities of LVLMs answering \u201cyes\u201d and \u201cno\u201d as an assessment of the model\u2019s confidence in answering the question.

Nevertheless, we intend to investigate more sophisticated classification strategies in the future to further enhance the detection of hallucinations.\n(2) Consider cross-modal attention of the first generated token: Our current approach exclusively utilizes cross-modal attention to image tokens during the generation of the initial token. This methodology is suitable for shorter-answer visual question answering (VQA) tasks. However, for longer-answer image captioning tasks, a more effective strategy would involve incorporating cross-modal attention at each token generation. Additionally, it would be beneficial to train the detector to differentiate between generated tokens that are hallucinations and those that are not.\n(3) Exploring the mitigation of hallucinations: Our approach centers on the detection of hallucinations in LVLMs and demonstrates commendable performance across a variety of tasks. For discriminative yes/no questions, our method effectively mitigates hallucinations by altering the provided answer. However, in the context of open-scene question and answer (Q&A) scenarios, we have yet to investigate solutions for hallucination mitigation through the application of our method. Addressing this gap will be a focus of our future research."

+            "text": "We summarise our motivation as follows:\n(1) The general idea of DHCP. To effectively detect hallucinations in LVLMs, it is essential to identify the differences between the hallucination and non-hallucination states. Notably, DHCP has identified a significant variation in the cross-modal attention patterns during large language model (LLM) decoding when an LVLM is experiencing hallucinations compared to when it is not. Consequently, we have developed a framework aimed at detecting and mitigating hallucinations, leveraging these cross-modal attention patterns.\n(2) Motivation for using a two-stage detectors. Our detector, which is based on cross-modal attention patterns, is structured as a two-stage process, taking into account several key considerations. One primary concern is the imbalance in the number of hallucination versus non-hallucination samples within the training set. Given that hallucinations in large vision-language models (LVLMs) are relatively rare, we have amassed a significantly greater number of non-hallucination samples than hallucination samples, with the ratio reaching as high as 9.45:1 for instances where the answer is \u201cYes\u201d. Even with the application of oversampling or undersampling techniques, achieving both high recall and precision with a single classifier remains challenging due to the data imbalance. In our two-stage detector design, the first-stage detector is optimized for high recall of hallucination samples, though it achieves a precision rate of only 50-60%. The second-stage detector, on the other hand, is trained using the samples identified as hallucinations in the first stage. At this point, the ratio of hallucination to non-hallucination samples in the training set is approximately 1:1, allowing us to train a more precise second-stage detector. Additionally, as illustrated in Fig. 2  ###reference_###, the responses \u201cyes\u201d and \u201cno\u201d correspond to distinct hallucination attention patterns. Therefore, it is advantageous to train separate hallucination detectors tailored to each type of response. This approach allows for more precise detection by accounting for the specific attention variations associated with each answer.\n(3) Using simple detectors lead to high efficiency. Our DHCP eliminates the need for pre-training, continued pre-training, or fine-tuning of LVLMs. Instead, it relies solely on training several additional, simply structured hallucination detectors to achieve high-performance hallucination detection. Furthermore, when addressing discriminative hallucination questions, our DHCP provides a \u201cfree lunch\u201d by mitigating hallucinations without incurring any extra inference steps for LVLMs, unlike OPERA and VCD, which both introduce additional inference costs. In summary, our DHCP is both efficient and effective."

+    "abstract": "Responding to misinformation online can be an exhausting and thankless task. It takes time and energy to write effective content, puts users at risk of online harassment, and strains personal relationships. Despite these challenges, there are people who voluntarily respond to misinformation online, and some have established communities on platforms such as Reddit, Discord, and X (formerly Twitter) dedicated to these efforts. In this work, we interviewed 8 people who participate in such communities to understand the type of support they receive from each other in these discussion spaces. Interviewees described that their communities helped them sustain motivation, save time, and improve their communication skills. Common practices included sharing sources and citations, providing emotional support, giving others advice, and signaling positive feedback. We present our findings as three case studies and discuss opportunities for future work to support collaborative practices in online communities dedicated to misinformation response. Our work surfaces how resource sharing, social motivation, and decentralization can make misinformation correction more sustainable, rewarding, and effective for online citizens.",

It requires significant time, energy, and trust to develop high-quality and source-backed content (Wilner et al., 2023  ###reference_b47###; Malhotra et al., 2023  ###reference_b26###). Being actively involved in such efforts also puts people in positions of high visibility and, consequently, high risk for harassment  (Schafer and Starbird, 2023  ###reference_b35###). Confronting someone about a misleading post can also strain or ruin relationships, especially with friends or family (Scott et al., 2023  ###reference_b36###; Feng et al., [n.\u2009d.]  ###reference_b18###). Past work has also shown that corrections may not actually be very effective (Ecker et al., 2022  ###reference_b16###) and can even potentially backfire (Mosleh et al., 2021  ###reference_b31###). Results of social corrections are heavily dependent on the receiver of the correction (Martel et al., 2021  ###reference_b27###), and this lack of control over positive outcomes can lead to feelings of burnout and pointlessness for people who confront misinformation regularly, such as health professionals  (Bautista et al., 2021  ###reference_b9###).\nDespite these challenges, there are still many people who voluntarily respond to misinformation online. Some have established communities on discussion-based platforms such as Reddit, Discord, and X to connect with others who engage in similar efforts including social correction, crowdsourced fact-checking, or peer victim support. In this work, we interviewed eight online citizens from such communities about how they interact with each other and present our findings as three case studies grouped by each online community\u2019s primary discussion topic and purpose. Case 1 focuses on a Discord server where regular contributors of Community Notes on X (formerly known as Birdwatch on Twitter) collaborated to produce politically balanced fact-checking notes. Case 2 consists of interviews with from members of r/QAnonCasualties and relevant communities where users discuss how conspiracy theories have affected themselves or their loved ones. Case 3 focuses on r/vaxxhappened, a subreddit where users repost screenshots of misleading information from external sources to debunk or vent about. Our research questions were the following:\nRQ1: What motivates people to voluntarily respond to misinformation?\nRQ2: What is the purpose of community for responders?\nRQ3: What are the factors that shape the collaborative practices within these communities?\nRQ4: What can we learn from existing communities and apply to future community-oriented misinformation interventions?\nOur interviews revealed the many collaborative practices that occur in these online communities and the ways peer interactions influenced individual motivations. In our discussion, we highlight three main themes participants relayed in their experiences. First, the resources and information shared by other members in these online communities saved users significant time and energy. Additionally, the social support found in these online communities helped to sustain motivation and provide valuable feedback. Finally, we observed that the decentralized nature of these online communities could produce more localized and engaging communications. We offer these considerations and opportunities for future work, and we emphasize the need for further research given our limited sample of participants from Western cultures.\nIn summary, this work explores the collaborative practices of online communities dedicated to voluntary misinformation by interviewing eight participants about their interactions with peers in their Reddit and Discord communities. We present our findings as three case studies with a focus on users\u2019 motivations. Our discussion explores opportunities to support and leverage their collaborative practices and underscores the need for research on global contexts. This empirical study adds to existing work on community-based approaches to combating misinformation by surfacing the collaborative practices of online communities dedicated to misinformation response and the potential ways they might increase or sustain motivation for more online citizens."

+            "text": "A large proportion of misinformation intervention research tends to focus on individual and platform-level interventions. On the individual level, prior misinformation intervention research has been conducted on topics such as developing a standardized set of credibility indicators for identifying credible content in articles (Zhang et al., 2018  ###reference_b49###). On the platform level, misinformation intervention work has focused on the design of \u201clightweight interventions\u201d that \u201cnudge\u201d the user to evaluate the accuracy and credibility of content before sharing on social media (Jahanbakhsh et al., 2021  ###reference_b22###). Additional research has been conducted about the ways in which individuals interact with and investigate misinformation on their social media feeds (Geeng et al., 2020  ###reference_b19###). There has also been related work about source-related misinformation interventions such as how media provenance can impact a user\u2019s perception about the trust and accuracy of social media content. Provenance is the information about the origins of a piece of digital media and any modifications made (Feng et al., 2023  ###reference_b17###) Other source-related mechanisms include developing checklists, toolkits, and the use of expert sources for individuals to evaluate online misinformation (heu, [n.\u2009d.]  ###reference_b2###). However, as Aghajari et al. emphasize, these types of individual and platform-based interventions place responsibility on the user and make the assumption that users are rational actors (Aghajari et al., 2023  ###reference_b7###). These approaches also fail to account for the social contexts in which individuals interact with misinformation and do not necessarily consider systemic impacts. Thus, more recent research in misinformation intervention has advocated for more socially embedded strategies such as social corrections and perceived norms (Aghajari et al., 2023  ###reference_b7###).\nSocial corrections are when people directly reply to or confront the individual who posted the misleading information. However, these are very difficult: they often lead to highly emotionally charged conversations, which can put pressure and tension on relationships, especially when the interaction occurs between people who are close at a personal level such as family and friends (Scott et al., 2023  ###reference_b36###). It can also be very tiring because it takes time to write responses with research-backed sources (bau, [n.\u2009d.]  ###reference_b3###; Bautista et al., 2021  ###reference_b9###; Wilner et al., 2023  ###reference_b47###). Engaging in misinformation response in a social setting can also expose people to harms like harassment and bullying  (Schafer and Starbird, 2023  ###reference_b35###). In addition to these risks, it also often does not feel rewarding since people are unlikely to change their mind immediately after being socially corrected (Ecker et al., 2022  ###reference_b16###). Thus, if we want to encourage social corrections, we should simultaneously look at ways to alleviate these burdens and make the experience less harmful for people, which is a core motivation for this work.\nAnother important social factor that has been studied is the effect of perceived norms on behaviors toward misinformation. Perceived norms have been shown to strongly influence people\u2019s behavior and attitudes toward believing in and sharing information. These can be leveraged to encourage positive actions and combat misinformation (Gimpel et al., 2021  ###reference_b20###). However, these same mechanisms can reinforce and perpetuate false beliefs or rumors, especially in closed networks (DiFonzo et al., 2013  ###reference_b13###). Other examples of community characteristics that can influence a community member\u2019s response to misinformation include the user\u2019s interaction patterns within a community, perceived norms around content produced and shared, network structures, and overall perspectives on different issues (Aghajari et al., 2023  ###reference_b7###)."

+            "text": "The motivations of voluntary participation in online communities of crowd-base knowledge production has been well-documented in CSCW literature about Wikipedia contributors (Kittur and Kraut, 2008  ###reference_b24###, 2010  ###reference_b25###; Zhang et al., 2017  ###reference_b48###; Zhu et al., 2013  ###reference_b50###), Reddit moderators(Seering and Kairam, 2023  ###reference_b37###; Squirrell, 2019  ###reference_b40###; Seering et al., 2019  ###reference_b38###), and open-source software developers (Vasilescu et al., 2013  ###reference_b44###, 2014  ###reference_b45###). Some have utilized social capital theory to explain the motivations of sustained voluntary participation in such communities (Qiu et al., 2019  ###reference_b33###; Nemoto et al., 2011  ###reference_b32###). In the present study, we aim to similarly understand the motivations of those who participate in another form of crowd-based knowledge production: crowdsourced fact-checking. Crowdsourced fact checking has a long history rooted in rumors and crisis response in which online citizens working together to dispel rumors in order to assist during emergent situations, such as the aftermath of the 2010 Haiti Earthquake  (Starbird and Palen, 2011  ###reference_b42###). Though these volunteers usually have positive intentions, online citizens unfortunately can make mistakes when attempting to verify unsubstantiated information as was surfaced after the 2013 Boston Marathon bombing (sta, 2014  ###reference_b6###).\nMore recently, new social computing systems have been developed to formalize and support crowds in fact-checking endeavors. In 2020*, X launched Community Notes 111https://help.twitter.com/en/using-x/community-notes (formerly known as Twitter and Birdwatch) and was one of the first prominent platforms that supported crowdsourced fact-checking. Community Notes allowed users to create community-driven \u201cnotes\u201d using a collaborative approach to provide more informative context to Tweets and address misinformation. The notes that contributors create are displayed on Tweets based on whether enough community members rate the note as helpful to, which helps ensure that diverse perspectives are considered (lor, [n.\u2009d.]  ###reference_b4###; x20, [n.\u2009d.]  ###reference_b5###). Existing research on Community Notes has focused mostly on the labor, value, reliability, and effectiveness of the system and its data (Jones et al., 2022  ###reference_b23###; Drolsbach and Pr\u00f6llochs, 2023  ###reference_b15###). Our work differs in that we are more interested in the motivations and collaborative practices of Community Notes contributors. We hypothesize that crowd fact-checkers may be more motivated by notions of civic duty than contributors in more subject-oriented crowd knowledge work like those on Wikipedia or Reddit.\nLastly, another area of research we draw upon is the collaborative practices of journalists and professional fact-checkers to verify information on the job (McClure Haughey et al., 2020  ###reference_b28###; Micallef et al., 2022  ###reference_b29###). Journalists and communicators rely on their professional communities and networks to validate information on breaking news together. Similarly, professional fact checkers develop pipelines of practices to overcome challenges they face when it comes to improving effectiveness, efficiency, scale, and reach (Sehat et al., 2024  ###reference_b39###). We examine whether these individual-level and community-level practices also arise among voluntary fact-checkers and similarly explore potential sociotechnical solutions that could assist those who engage in this work."

Eventually, early adopters in the Discord devised a set of guidelines that were integrated into the platform:\n\u201cEarly on, we had a lot of discussions on how to write notes \u2026 because most people don\u2019t know how to write quality material.

One of the ways that their participants coped with this pressure was to build upon existing resources from other information professionals in online forums such as lesson plans and instructional materials. Participants in our study engaged in similar practices like content co-creation, resource sharing, and peer learning saved members time, energy, and effort. For example, in Case 1, members of the Community Notes Discord innovated various optimizations such as the #sources-and-citations, #templates, and #rapid-response text channels. By combining their information and resources, they reduced the amount of time it took to detect, research, and respond to \u201chigh velocity\u201d tweets. The group\u2019s collective knowledge also benefited from contributions of users with niche subject matter expertise.\nAlthough other communities in our study were not as explicitly dedicated to fact-checking, they still developed similar practices that improved misinformation response efficiency. In Case 2, users in r/QAnonCasualties and related communities shared success stories and communication tips. P6\u2019s weekly Discord calls were another example in which members shared their time and resources to improve each other\u2019s skills. Additionally, when r/vaxxhappened users debunked misinformation through Reddit post replies, their comments became reusable archives of sources and citations. Future work could explore developing sociotechnical systems specifically designed for these communities of practice to save voluntary misinformation responders significant time, energy, and effort. For example, commonly upvoted sources, tips, and citations could be organized and pinned for future access and reuse."

Past work has shown that social norms can counter these potential negative consequences and increase likelihood of engaging in corrections (Aghajari et al., 2023  ###reference_b7###). Our findings point to similar opportunities to encourage voluntary misinformation response through social motivation in online communities. For example, P6 described that the nature of their work debunking conspiracy theories was \u201cnot a joy\u201d, but the encouragement and humor they found through their community kept them going. Relatedly, the comedic relief that users produced in r/vaxxhappened was central to the community\u2019s growth and success. Simply having a place to meet others with similar values, goals, and motivations may help sustain otherwise thankless efforts.\nIn addition to providing emotional support, peer interactions can also help responders gauge the success of their communications. Bautista et al. found that many health professionals lose motivation to engage in social media and online communications due to the lack of measurable positive outcomes (Bautista et al., 2021  ###reference_b9###). P6 similarly described that they have no way of knowing how many people have productive conversations with loved ones as a result of their YouTube content. P4 from the Community Notes Discord stopped sharing their templates with others because they did not know if anyone was using them. Future work could investigate how to capture and transform peer support in these communities into visible metrics. Implementing such systems could make responders feel more appreciated for their voluntary labor, similar to how some Reddit moderators favored Moderator Appreciation Days or profile badges (Dosono and Semaan, 2019  ###reference_b14###; Cai et al., 2021  ###reference_b11###). Additionally, our participants all had intrinsic motivations that compelled them to join such communities in the first place. Studying ways to sustain their motivations could unlock opportunities to promote voluntary misinformation correction as a social norm for general populations beyond already-interested users."

Collaborating with these trusted messengers is especially effective for reaching marginalized groups since misinformation can be very sensitive, racialized, and politicized. In our study, we observed how P6\u2019s European \u201cspinoff\u201d of r/QAnonCasualties facilitated resources and events local to their region. The community was created because the original r/QAnonCasualties community was for English speakers in the US, which was not always accessible or applicable for international users. For example, the conspiracy theory groups active in their country went by a different name, and they frequently engaged in code switching throughout their interview to describe community phenomena. Future work should examine the potential of online communities for localized voluntary misinformation response, especially since our study is limited to users from Western cultures.\nAnother potential benefit of online communities for misinformation response is that their decentralized nature might reach larger and more peripheral audiences. Starbird et al. found that in disinformation campaigns, online communities drew informal participation from a wide range of users from forum moderators to activist grandmothers (Starbird et al., 2019  ###reference_b41###). These \u201ccitizen marketers\u201d engaged in a \u201cself-sustaining web of interdependent collaborative practices\u201d similar to what is found in online fan communities. Our findings in Case 3, r/vaxxhappened, surfaced a similar ecosystem of media production and dissemination. Users created memes and entertaining content, and these artifacts would carry forward messages in unpredictable ways. P3, our main participant of Case 3, was not from the US but still participated in the US-centric community because they found the collaborative practices interesting and fun. This could also explain why the subreddit has over 350k members despite its niche topic and strict moderation policies. Future approaches to community-based misinformation response should explore how to blend top-down, institutional support with grassroots, voluntary community-based action. This is especially important since members like P3 today frequently expose themselves to misinformation and potential harassment when seeking content to repost. More organized efforts could protect users from these harms and scale these communities\u2019 impact."
