Product Entity Matching by Leveraging Tabular Data
Creators: Naeim Abadi, Ali
Publisher: name: University of Alberta Library
Year: 2023

Product Entity Matching (PEM) is a challenging subfield of record linkage that involves linking records referring to the same real-world product. Despite recent transformer models showing near-perfect performance scores on various datasets, they struggle the most when dealing with PEM datasets. In this thesis, we study PEM under the common setting where the information is spread over text and tables. To facilitate our research, we introduce a new dataset based on existing Amazon, Walmart and Google datasets, where each product contains a mix of both textual and tabular details. Our hypothesis is that leveraging detail tables alongside textual data can effectively tackle complex entity matching tasks where textual information alone falls short. However, existing models have proven to be inefficient and ineffective in utilizing such tabular data. We propose TATEM and TATTOO models, which offer an effective solution by harnessing pre-trained language models along with a novel serialization technique to encode tabular product data. Our models incorporate a novel attribute ranking module to make our model more data-efficient. Our experiments on both current benchmark datasets and our proposed datasets show significant improvements compared to state-of-the-art methods, including large language models in zero-shot and few-shot settings. Moreover, in out-of-domain and few-shot experiments, the TATTOO model showcases its superiority by outperforming strong baselines by a substantial margin.

description: Quantum filtering is a signal processing technique that estimates the posterior state of a quantum system under continuous measurements and has become a standard tool in quantum information processing, with applications in quantum state preparation, quantum metrology, and quantum control. If the filter assumes a nominal model that differs from reality, however, the estimation accuracy is bound to suffer. Here I derive identities that relate the excess error caused by quantum filter mismatch to the relative entropy between the true and nominal observation probability measures, with one identity for Gaussian measurements, such as optical homodyne detection, and another for Poissonian measurements, such as photon counting. These identities generalize recent seminal results in classical information theory and provide new operational meanings to relative entropy, mutual information, and channel capacity in the context of quantum experiments.

description: We show that a standard model gauge singlet fermion field, with mass of order keV or larger, and involved in the inverse seesaw mechanism of light neutrino mass generation, can be a good warm dark matter candidate. Our framework is based on B-L extension of the Standard Model. The construction ensures the absence of any mixing between active neutrinos and the aforementioned dark matter field. This circumvents the usual constraints on the mass of warm dark matter imposed by X-ray observations. We show that over-abundance of thermally produced warm dark matter (which nevertheless do not reach chemical equilibrium) can be reduced to an acceptable range in the presence of a moduli field decaying into radiation --- though only when the reheat temperature is low enough. Our warm dark matter candidate can also be produced directly from the decay of the moduli field during reheating. In this case, obtaining the right amount of relic abundance, while keeping the reheat temperature high enough as to be consistent with Big Bang nucleosynthesis bounds, places constraints on the branching ratio for the decay of the moduli field into dark matter.

Post-Soviet film

description: This thesis contends that the selected four post-Soviet Russian film-texts, following the dissolution of the Soviet Union i.e., total ideological, political and socio-economic melt down, provide a useful context for discussing the reconstruction of Russian national identity. This study aims to reveal post-Soviet films in the late 90s and early 2000s as part of a discourse of the re-mythologization of national identity in Russia. The films to be analyzed are in a dialogue within the national discourse constructed through the literary and auditory texts of post-Soviet films that centrally discuss the question of “Russianness”. The framework in studying the four film-texts as part of a cultural discourse is post-colonial theory, will utilize Edward Said’s Orientalism and Homi Bhabha’s “DissemiNation: time, narrative, and the margins of the modern nation,” in Nation and Narration, and Benedict Anderson’s constructivist notion of nation in his work Imagined Communities. The mentioned works will provide a conceptualization of the cultural problematique of a post-empire national identity construction in Russia

On Resource Allocation in Time-constrained Coded Distributed Computing Systems
Creators: Mehrabi, Mehrad
Publisher: name: University of Alberta Library
Year: 2023

Distributed computing systems have been widely used in recent years to handle massive computations required by newly emerged machine learning algorithms and signal processing problems. Also, the use of error correction codes has been proposed to mitigate the negative impact of slow workers by adding redundancy to the computational tasks. In practice, a distributed computing system often receives multiple tasks each needs to be finished by a specific deadline. Furthermore, service providers may offer different levels of service based on their users' subscription tiers. In this thesis, we first consider a scenario where multiple matrix-vector multiplication jobs arrive in a distributed computing system. The main challenges in such a system are random task arrivals and random execution times due to the slow workers. To address these challenges, we present two algorithms to maximize the number of tasks completed before their  deadlines. Then, we study a tiered time-constrained distributed computing system, where there are multiple users with distinct subscription classes and each with a time-sensitive computational job. We assume the system receives rewards for finishing tasks prior to their deadlines and gives higher priority to tasks associated with higher subscription tiers. To maximize the overall reward of the system, we present a worker assignment scheme. In both studies, it is shown that our proposed algorithms provide comparable performances to unachievable upper bounds while exhibiting significantly lower complexity.
Genetic structure of a large recolonizing carnivore: the case of the northern cougars (Puma concolor)
Creators: Barrett, Kimberley G
Publisher: name: University of Alberta Library
Year: 2023

Anthropogenic activities have pressured and altered landscapes resulting in extinctions and extirpations. However, increased conservation efforts and changing management strategies in some large carnivores have resulted in population and range expansion. Population growth and range expansion are detectable using population genetic techniques by characterizing population structure, and clinal patterns in relatedness (isolation by distance, IBD). Using 902 single nucleotide polymorphisms genotyped via double digestion restriction-site associated digestion from 119 cougars (Puma concolor) – both live-captured and harvested cats – in Alberta, Canada we assessed and characterized the genetic structure of this expanding population using spatially explicit and agnostic means. Each predicted and tested subpopulation (based on geographic attributes of sampling location) was characterized and mapped. Predicted subpopulations were inconsistent and not biologically informative; additionally, no significant correlation was detected between genetic and geographic distance (IBD). In all tested and predicted subpopulations, observed heterozygosity was lower than expected. Our findings confirm that the Albertan population of cougars has recently undergone expansion detectable from a genetic perspective (as suggested by the lower-than-expected heterozygosity). The panmictic nature of this population is unique in modern cougars and of importance for managers both of this population and of other predator species.

description: Self-interacting dark matter (SIDM) models have been proposed to solve the small-scale issues with the collisionless cold dark matter (CDM) paradigm. We derive equilibrium solutions in these SIDM models for the dark matter halo density profile including the gravitational potential of both baryons and dark matter. Self-interactions drive dark matter to be isothermal and this ties the core sizes and shapes of dark matter halos to the spatial distribution of the stars, a radical departure from previous expectations and from CDM predictions. Compared to predictions of SIDM-only simulations, the core sizes are smaller and the core densities are higher, with the largest effects in baryon-dominated galaxies. As an example, we find a core size around 0.5 kpc for dark matter in the Milky Way, more than an order of magnitude smaller than the core size from SIDM-only simulations, which has important implications for indirect searches of SIDM candidates.

Year: 2017

description: Background: Post- operative prosthetic joint infection (PJI) is the most common cause of failure of total joint arthroplasty, requiring revision surgery, but a gold standard for the diagnosis and the consequent treatment of PIJ is still lacking. Among the scenario of infections diagnosis, an emerging molecule is Presepsin, the soluble fraction of CD14, recently described as a powerful diagnostic tool, not only to detect sepsis but also to discriminate different grade of sepsis severity. Question / purpose: We asked:1) is Presepsin a good diagnostic marker for PJI? 2) Does Presepsin correlate with other emerging infection markers such as TREM-1, CD-163, SuPAR, OPN and MMP-9, sTLR2 and CCL2 and IL-6?3) Is Presepsin a good prognostic marker of PJI? Methods: The population of 100 selected patients undergoing prosthesis revision was enrolled and subdivided into two groups: 48 patients having bacterial infection and 52 patients with no infection, undergoing aseptic loosening of the implant. CRP was measured using immunoturbidimetry on an automated biochemical analyzer (Olympus CRP-Latex assay, Central Valley, PA, CA, USA) Serum IL-6, TREM-1, CCL2, MMP-9, CD-163 and OPN were measured using an ELISA sandwich Quantikine Assay, while TLR2 was measured using an ELISA Duo Set Assay, according to manufacturer protocol (R&D System, Minneapolis, MN, USA). SuPAR was measured by SuPARnostic ELISA Assay, according to manufacturer protocol (Virogates, Denmark). Presepsin plasmatic levels were measured by Presepsin/ PATHFAST according to manufacturers? protocol (Mitsubishi Chemical). PATHFAST Presepsin is a chemioluminescent enzyme immune assay (CLEIA) for the quantitative measurement of Presepsin concentration in whole blood or plasma. Results: Presepsin has a greater diagnostic value than CRP and IL-6 in the diagnosis of PJI, as assessed by ROC CURVE analysis. OPN, CCL2, TLR2 and SuPAR displayed good diagnostic values in PJI, while CD163, TREM-1 and MMP-9 displayed very low diagnostic potential. Presepsin, as well as OPN, CCL2, SuPAR and TLR2, displayed a significant decrease at the increasing time of recovery after surgery in PJI patients, while it remains unaltered and significantly lower (p<0.0001) in the patients undergone to revision surgery for aseptic loosening of the implant. These results clearly indicate that Presepsin have a good prognostic value, because it decreases gradually as the inflammatory process in response to the prosthetic infection is resolved. Conclusions: Taken together, these results indicate that Presepsin can be considered a useful tool for the diagnosis and clinical monitoring of PJI, and it can also be supported by a panel of new inflammatory makers involved in monocyte/macrophage mediated inflammatory response such as OPN, CCL2, TLR2 and SuPAR.
Probability Distributions on a Circle

Distributions of sequences modulo one (mod 1) have been studied over the past century with applications in algebra, number theory, statistics, and computer science. For a given sequence, the weak convergence of the associated empirical distributions has been the usual approach to these studies. In this thesis, we give a formula for calculating the Kantrovich distance between mod 1 probability measures. We then use this distance to study the convergence behavior of the (mod 1) empirical distributions associated with real sequences (xn)∞ n=1 for which limn→∞ n(xn−xn−1) exists. We find that for such sequences, every probability distribution in the limit set of the empirical distributions is a rotated version of a certain exponential distribution. We also describe the speed of convergence to this limit set of distributions.

description: In this paper, the highly transient keyhole dynamics, e.g., laser absorption, keyhole geometry, and fluctuation, etc., under a magnetic field are investigated using an experimental approach and multi-physical modeling. The model provides accurate predictions to the variation of penetration depth and weld pool profiles caused by the MHD effect, which is validated by the measurements of optical micrographs and in-situ metal/glass observation. The micro-X-ray computed tomography shows a remarkable reduction of keyhole-induced porosity with the magnetic field. The correlation between the porosity mitigation and the weld pool dynamics influenced by the magnetic field is built comprehensively. It is found that the magnetic field gives a direct impact on the laser energy absorption at the keyhole front wall by changing the protrusion movement. The porosity mitigation comes from multiple physical aspects, including keyhole stabilization, widening of the bubble floating channel, and the electromagnetic expulsive force. Their contributions vary according to the bubble size. The findings provide a deeper insight into the relationship between electromagnetic parameters, keyhole dynamics, and suppression of keyhole-relevant defects.
Exploring Surprisal from Various Language Models for Predicting English Reading Times of People with Different Language Backgrounds
Creators: Clark, Shannon R
Publisher: name: University of Alberta Library
Year: 2023

Surprisal estimated by language models is predictive of reading time in first-language (L1) reading. Research is emerging to determine whether this observation extends to reading in a second language (L2). Current attempts to characterize differences in the predictive power of surprisal for L1 and L2 reading times lack exploration of the reader's language background. As such, this thesis aims to evaluate the performance of surprisals derived from various language models for predicting English reading times of people with different L1s. To this end, we trained nine language models that varied in the extent of syntactic information, lexical information, and preceding context they used to compute surprisal. Next, we developed generalized additive mixed models to predict the English reading times of L1 speakers of English, Chinese, Korean, and Spanish using surprisal. Our results showed several commonalities. First, the best-performing surprisal for all language backgrounds was derived from a standard n-gram or an n-gram with added part-of-speech tags. Second, the lexical portion of total surprisal from a probabilistic context-free grammar performed more poorly than the syntactic portion. Last, out of the surprisals estimated using only syntactic information, those that accounted for the hierarchical structure of sentences outperformed the one based purely on sequential representations. Apart from these similarities, we observed differences by language background. It appears that surprisal computed using richer context performed better for L1 speakers of left-branching languages. It also seems that surprisals derived using hierarchical syntactic information performed better for languages with a different word order than English. Further research is needed to fully characterize these differences in performance in terms of the linguistic features of the reader's L1 and the way each language model computes surprisal. Our work shows that a variety of language models produce surprisals predictive of L1 and L2 reading times in English. Since the performance of these surprisals varied by the reader's L1, our work suggests that it is important to consider language background when using language models in the study of L2 reading.
A Model of bubble nucleation efficiency for bubble chamber detector
Creators: Li, Xiang
Publisher: name: University of Alberta Library
Year: 2023

Bubble chambers using fluorocarbons or noble liquids gases are promising tools for detecting low-energy nuclear recoils caused by the elastic scattering of weakly interacting massive particles (WIMPs), a type of dark matter. These chambers comprise a vessel filled with a superheated liquid, which is controlled in terms of pressure and temperature. Bubble formation occurs when the energy deposition surpasses a specific threshold defined by the "heat-spike" Seitz Model. The efficiency of bubble nucleation from low-energy nuclear recoils in superheated liquids is a crucial factor in interpreting results obtained from direct searches for WIMPs as dark matter. This study aims to develop a physics model capable of explaining the observed disparities between experimental outcomes and the current Seitz model. Molecular dynamics simulations were utilized to investigate the bubble nucleation threshold, and a Monte Carlo simulation employing SRIM was performed to obtain the energy transfer in the target medium. The model also incorporates Lindhard's theory to enhance accuracy and improve predictions of bubble nucleation efficiency. By applying nucleation efficiency, we can estimate the cross-section exclusion limit for experiments. The model has been tested with existing experimental data and shows similar detector responses.

description: Motivated by the recent literature that finds that artificial neural networks (NN) can efficiently predict economic time‐series in general and inflation in particular, we investigate if the forecasting performance can be improved even further by using a particular kind of NN—a recurrent neural network. We use a long short‐term memory recurrent neural network (LSTM) that was proven to be highly efficient for sequential data and computed univariate forecasts of monthly US CPI inflation. We show that even though LSTM slightly outperforms autoregressive model (AR), NN, and Markov‐switching models, its performance is on par with the seasonal autoregressive model SARIMA. Additionally, we conduct a sensitivity analysis with respect to hyperparameters and provide a qualitative interpretation of what the networks learn by applying a novel layer‐wise relevance propagation technique.

First, we show that the junction can be used as a versatile spin filter as a function of a backgate and a static external magnetic field. Switching between opposite spin filter directions can be achieved by small changes of the backgate potential, and a full polarization is generically obtained in an energy range close to the Dirac points. Second, we discuss how the spin filtering properties affect the noise correlators of entangled electron pairs, which allows us to obtain signatures of the type of entanglement that are different from the signatures in conventional semiconductor cross-junctions.

description: This work is concerned with determination of the steady-state structure of time-independent Lindblad master equations, especially those possessing more than one steady state. The approach here is to treat Lindblad systems as generalizations of unitary quantum mechanics, extending the intuition of symmetries and conserved quantities to the dissipative case. We combine and apply various results to obtain an exhaustive characterization of the infinite-time behavior of Lindblad evolution, including both the structure of the infinite-time density matrix and its dependence on initial conditions. The effect of the environment in the infinite time limit can therefore be tracked exactly for arbitrary state initialization and without knowledge of dynamics at intermediate time. As a consequence, sufficient criteria for determining the steady state of a Lindblad master equation are obtained. These criteria are knowledge of the initial state, a basis for the steady-state subspace, and all conserved quantities. We give examples of two-qubit dissipation and single-mode $d$-photon absorption where all quantities are determined analytically. Applications of these techniques to quantum information, computation, and feedback control are discussed.

The future influences of climate change and river regulation on high-latitude circulation as determined by ocean modelling

The Hudson Bay Complex (HBC), encompassing Foxe Basin (FB), Hudson Strait (HS), Ungava Bay (UB), Hudson Bay (HB), and James Bay (JB), experiences notable shifts in freshwater sources. Despite being smaller than the Arctic Ocean, the HBC annually receives around 900 km3 of river discharge, constituting about 25% of the Arctic Ocean's inflow.

The HBC receives freshwater primarily from river runoff and ice freeze-thaw processes, both impacted by human activities (e.g., diversions, dams, and reservoirs) and climate change. Using the NEMO ocean-sea ice model with the Arctic and Northern Hemisphere Atlantic (ANHA) configuration, we investigated how river regulation and climate change affect HBC's freshwater dynamics.

We applied an ensemble of five climate simulations, which were from the Coupled Model Inter-comparison Project 5 (CMIP5) model experiments. They were initialized between 1980 and 2005, forced with naturalized and regulated river runoff, and driven by different representative concentrations of greenhouse gases (RCP4.5 and RCP8.5) over the 2006-2070 period. The results showed a general increase in freshwater content, along with a sharp decrease in ice thickness and concentration in the future. The mixed layer depth can reach up to 230 m near the north side of HS. With increased freshwater from rivers and ice thawing, future mixed layers are projected to be slightly shallower compared to the historical period. Finally, we examined atmospheric forcing changes to understand ocean-sea ice-atmosphere interactions in a changing climate. Our results reveal significant impacts of distinct ensemble members on salinity and freshwater content variations, reflecting hydrological cycle evolution in climate models. Differences in content between naturalized and regulated regimes are linked to factors including freshwater residence time and discharge timing.

description: Necessary and sufficient conditions for convexity and strong convexity, respectively, of sublevel sets that are defined by finitely many real-valued $C^{1,1}$-maps are presented. A novel characterization of strongly convex sets in terms of the so-called local quadratic support is proved. The results concerning strong convexity are used to derive sufficient conditions for attainable sets of continuous-time nonlinear systems to be strongly convex. An application of these conditions is a novel method to over-approximate attainable sets when strong convexity is present.

description: We consider priced timed Petri nets, i.e., unbounded Petri nets where each token carries a real-valued clock. Transition arcs are labeled with time intervals, which specify constraints on the ages of tokens. Furthermore, our cost model assigns token storage costs per time unit to places, and firing costs to transitions. This general model strictly subsumes both priced timed automata and unbounded priced Petri nets. We study the cost of computations that reach a given control-state. In general, a computation with minimal cost may not exist, due to strict inequalities in the time constraints. However, we show that the infimum of the costs to reach a given control-state is computable in the case where all place and transition costs are non-negative. On the other hand, if negative costs are allowed, then the question whether a given control-state is reachable with zero overall cost becomes undecidable. In fact, this negative result holds even in the simpler case of discrete time (i.e., integer-valued clocks).
