description: We consider a special type of Restricted Boltzmann machine (RBM), namely a Gaussian-spherical RBM where the visible units have Gaussian priors while the vector of hidden variables is constrained to stay on an ${\mathbbm L}_2$ sphere. The spherical constraint having the advantage to admit exact asymptotic treatments, various scaling regimes are explicitly identified based solely on the spectral properties of the coupling matrix (also called weight matrix of the RBM). Incidentally these happen to be formally related to similar scaling behaviours obtained in a different context dealing with spatial condensation of zero range processes. More specifically, when the spectrum of the coupling matrix is doubly degenerated an exact treatment can be proposed to deal with finite size effects. Interestingly the known parallel between the ferromagnetic transition of the spherical model and the Bose-Einstein condensation can be made explicit in that case. More importantly this gives us the ability to extract all needed response functions with arbitrary precision for the training algorithm of the RBM. This allows us then to numerically integrate the dynamics of the spectrum of the weight matrix during learning in a precise way. This dynamics reveals in particular a sequential emergence of modes from the Marchenko-Pastur bulk of singular vectors of the coupling matrix.

Subjects: subject: Annual Report

description: Die nur teilweise entzifferte Hieroglyphenschrift und Sprache der Mayakultur steht im Mittelpunkt des hier zur Diskussion stehenden Forschungsprojekts, das in Kooperation zwischen den Universitäten Bonn und Göttingen durchgeführt wird. Ziel ist die Erstellung einer Textdatenbank und ein darauf basierendes Wörterbuch des Klassischen Maya (Blütezeit von 250 bis 950 n. Chr.). Aus dieser Zeit sind rund zehntausend Text- und Bildträger überliefert, die mit ihren schriftlichen und bildlichen Informationen einzigartige Perspektiven auf Sprache, Kultur und Geschichte dieser vorspanischen Gesellschaft aufzeigen. Bis heute fehlen allerdings eine systematische Dokumentation und eine umfassende Analyse der Bild- und Textträger, die eine eingehende und präzise Untersuchung der Klassischen Schriftsprache erlauben, indem etwa Textpassagen mit Hilfe einer Kotext- und Kookkurrenzanalyse verglichen werden, Bildinhalte mit Textpassagen korreliert oder die Beschaffenheit oder Funktion eines Textträger in der Inschrift erfasst und damit unklare Textpassagen möglicherweise verständlich werden. Bislang war ein derartig systematisches und vernetztes Arbeiten mit Text, Bild und Informationsträgern nicht möglich, da die dafür notwendige Technologie in diesem Fach noch nicht existierte. Im Rahmen des Projekts werden die Text- und Bildträger systematisch und nach einheitlichen Standards beschrieben, das Ausgangsmaterial auf der Basis von XML maschinenlesbar gemacht und auf diese Weise die Grundlagen für die Kompilation des Wörterbuchs geschaffen. Dieses Unterfangen kann nur mit Methoden und Technologien aus den digitalen Geisteswissenschaften in Angriff genommen werden, wobei das Projekt auf Tools und Technologien zurückgreift, die in der Virtuellen Forschungsumgebung (Virtual Research Environment, VRE) TextGrid bereits vorhanden sind bzw. im Rahmen des Projektes entwickelt und implementiert werden. Wesentliche Voraussetzung ist dabei, dass nicht nur der sprachliche Inhalt der Inschriften und die ikonischen Informationen der Bilddarstellungen, sondern auch Daten über den Inschriften- und Bildträger (Beschreibungs- oder Metadaten) berücksichtigt und in einer Datenbank angelegt werden.

description: We investigate the relationship between social media, Twitter in particular, and stock market. We provide an in-depth analysis of the Twitter volume and sentiment about the 30 companies in the Dow Jones Industrial Average index, over a period of three years. We focus on Earnings Announcements and show that there is a considerable difference with respect to when the announcements are made: before the market opens or after the market closes. The two different timings of the Earnings Announcements were already investigated in the financial literature, but not yet in the social media. We analyze the differences in terms of the Twitter volumes, cumulative abnormal returns, trade returns, and earnings surprises. We report mixed results. On the one hand, we show that the Twitter sentiment (the collective opinion of the users) on the day of the announcement very well reflects the stock moves on the same day. We demonstrate this by applying the event study methodology, where the polarity of the Earnings Announcements is computed from the Twitter sentiment. Cumulative abnormal returns are high (2--4\%) and statistically significant. On the other hand, we find only weak predictive power of the Twitter sentiment one day in advance. It turns out that it is important how to account for the announcements made after the market closes. These after-hours announcements draw high Twitter activity immediately, but volume and price changes in trading are observed only on the next day. On the day before the announcements, the Twitter volume is low, and the sentiment has very weak predictive power. A useful lesson learned is the importance of the proper alignment between the announcements, trading and Twitter data.

description: Mobile banking (M-bank), a newly introduced technology, can improve women’s access to financial services. This study empirically estimates the effect of a husband’s and wife’s socioeconomic characteristics, relative differences in age and education, and household characteristics on M-bank use in northern Bangladesh, exploring the presence and possible effect of the gender gap between husband and wife. A couple’s relative differences in age or education can function as a proxy to capture the wife’s M-bank use, thereby, her financial responsibilities in the household. The empirical evidence is based on a two-equation probit estimation that predicts the possible determinants of M-bank use by husbands and wives. M-bank use of husbands and wives differed remarkably, with wife to husband ratio of 4:15. Households were categorized into three subgroups: wife user, husband user, and nonuser. Results show that a husband’s level of education, having his own business, and having a migrant family member within the household have a statistically significant positive effect on the likelihood of him using M-bank. On the other hand, a wife with an education level higher than that of her husband’s has a significant positive effect on the likelihood of her using M-bank. A substantial gender gap in M-bank use, favoring husbands, was observed in most couples where the husband has more schooling than the wife and vice versa. The impact of M-bank use must be critically studied, focusing on the couple’s relative status due to the gender gap in educational attainment and positive relative characteristics of couples in patriarchal, Islamic, rural settings in Bangladesh.

description: We present APAC-Net, an alternating population and agent control neural network for solving stochastic mean field games (MFGs). Our algorithm is geared toward high-dimensional instances of MFGs that are beyond reach with existing solution methods. We achieve this in two steps. First, we take advantage of the underlying variational primal-dual structure that MFGs exhibit and phrase it as a convex-concave saddle point problem. Second, we parameterize the value and density functions by two neural networks, respectively. By phrasing the problem in this manner, solving the MFG can be interpreted as a special case of training a generative adversarial network (GAN). We show the potential of our method on up to 100-dimensional MFG problems.

description: We show the arbitrarily long-term stability of conservative methods for autonomous ODEs. Given a system of autonomous ODEs with conserved quantities, if the preimage of the conserved quantities possesses a bounded locally nite neighborhood, then the global error of any conservative method with the uniformly bounded displacement property is bounded for all time, when the uniform time step is taken suciently small. On nite precision machines, the global error still remains bounded and independent of time until some arbitrarily large time determined by machine precision and tolerance. The main result is proved using elementary topological properties for discretized conserved quantities which are equicontinuous. In particular, long-term stability is also shown using an averaging identity when the discretized conserved quantities do not explicitly depend on time steps. Numerical results are presented to illustrate the long-term stability result.

description: The development of new treatments to aid patients who suffer from rare diseases is a challenging area of medicine, particularly since the patient populations are limited. Therefore, traditional clinical trial designs and their sample size calculations often require a large proportion of the total patient population to be recruited into the clinical trial. Due to this, many novel designs of clinical trials seek to increase the benefit to the patients recruited into the trials. This is a motivation for response adaptive randomisation designs and their extension, covariate adjusted response adaptive (CARA) randomisation designs. These designs use previous patients' outcomes (and the CARA design also uses the previous patients' covariates) from within the trial to predict which treatment will be superior for future patients, and prioritise the allocation of said predicted superior treatment. In this thesis, two methods to maximise the benefit to patients are explored. The first method focuses on increasing the benefit to patients within the trial. A CARA trial design, which can be used for several different types of covariates and patient outcomes, is explored using two simulation studies; one includes a continuous covariate and outcome, the other includes two binary covariates and a survival outcome. The design is then extended to incorporate historical trial data. This extension is evaluated using two simulations studies that incorporate a continuous covariate and outcome. Different versions of both trial designs are evaluated in simulations across a wide range of scenarios. The second method is an alternative sample size calculation for a randomised controlled trial, which optimises the trial sample size such that the benefit to the whole patient population is maximised. Two different versions of the approach are investigated and compared using a continuous patient outcome trial, for a range of scenarios.

description: Reactive systems à la Leifer and Milner, an abstract categorical framework for rewriting, provide a suitable framework for deriving bisimulation congruences. This is done by synthesizing interactions with the environment in order to obtain a compositional semantics. We enrich the notion of reactive systems by conditions on two levels: first, as in earlier work, we consider rules enriched with application conditions and second, we investigate the notion of conditional bisimilarity. Conditional bisimilarity allows us to say that two system states are bisimilar provided that the environment satisfies a given condition. We present several equivalent definitions of conditional bisimilarity, including one that is useful for concrete proofs and that employs an up-to-context technique, and we compare with related behavioural equivalences. We consider examples based on DPO graph rewriting, an instantiation of reactive systems.

description: A new model validation and performance assessment tool is introduced, the sliding threshold of observation for numeric evaluation (STONE) curve. It is based on the relative operating characteristic (ROC) curve technique, but instead of sorting all observations in a categorical classification, the STONE tool uses the continuous nature of the observations. Rather than defining events in the observations and then sliding the threshold only in the classifier (model) data set, the threshold is changed simultaneously for both the observational and model values, with the same threshold value for both data and model. This is only possible if the observations are continuous and the model output is in the same units and scale as the observations, that is, the model is trying to exactly reproduce the data. The STONE curve has several similarities with the ROC curve, plotting probability of detection against probability of false detection, ranging from the (1,1) corner for low thresholds to the (0,0) corner for high thresholds, and values above the zero-intercept unity-slope line indicating better than random predictive ability. The main difference is that the STONE curve can be nonmonotonic, doubling back in both the x and y directions. These ripples reveal asymmetries in the data-model value pairs. This new technique is applied to modeling output of a common geomagnetic activity index as well as energetic electron fluxes in the Earth's inner magnetosphere. It is not limited to space physics applications but can be used for any scientific or engineering field where numerical models are used to reproduce observations.

description: We use the framework of the p19MSSM to perform a fit to the mild excesses over the Standard Model background recently observed in three bins of the ATLAS 1-lepton + (b-)jets + MET search. We find a few types of spectra that can fit the emerging signal and at the same time are not excluded by other LHC searches. They can be grouped roughly in two categories. The first class is characterized by the presence of one stop or stop and sbottoms with mass in the ballpark of 700-800 GeV and a neutralino LSP of mass around 400 GeV, with or without the additional presence of an intermediate chargino. In the second type of scenarios the stop, lightest chargino, sbottom if present, and the neutralino are about or heavier than ~650 GeV and the signal originates from cascade decays of squarks of the 1st and 2nd generation, which should have a mass of 1.1-1.2 TeV. For the best-fit scenarios, we compare the global chi-squared with respect to several ATLAS and CMS searches with the corresponding chi-squared of the Standard Model expectation, showing that the putative signal is also favored globally with respect to the background only hypothesis. We point out that if the observed excess persists in the next round of data, it should be accompanied by associated significant excesses in all-hadronic final state searches.

description: In this paper we describe a method to discover frequent behavioral patterns in event logs. We express these patterns as \emph{local process models}. Local process model mining can be positioned in-between process discovery and episode / sequential pattern mining. The technique presented in this paper is able to learn behavioral patterns involving sequential composition, concurrency, choice and loop, like in process mining. However, we do not look at start-to-end models, which distinguishes our approach from process discovery and creates a link to episode / sequential pattern mining. We propose an incremental procedure for building local process models capturing frequent patterns based on so-called process trees. We propose five quality dimensions and corresponding metrics for local process models, given an event log. We show monotonicity properties for some quality dimensions, enabling a speedup of local process model discovery through pruning. We demonstrate through a real life case study that mining local patterns allows us to get insights in processes where regular start-to-end process discovery techniques are only able to learn unstructured, flower-like, models.

description: Recent improvements in data collection volume from planetary and space physics missions have allowed the application of novel data science techniques. The Cassini mission for example collected over 600 gigabytes of scientific data from 2004 to 2017. This represents a surge of data on the Saturn system. Machine learning can help scientists work with data on this larger scale. Unlike many applications of machine learning, a primary use in planetary space physics applications is to infer behavior about the system itself. This raises three concerns: first, the performance of the machine learning model, second, the need for interpretable applications to answer scientific questions, and third, how characteristics of spacecraft data change these applications. In comparison to these concerns, uses of black box or un-interpretable machine learning methods tend toward evaluations of performance only either ignoring the underlying physical process or, less often, providing misleading explanations for it. We build off a previous effort applying a semi-supervised physics-based classification of plasma instabilities in Saturn's magnetosphere. We then use this previous effort in comparison to other machine learning classifiers with varying data size access, and physical information access. We show that incorporating knowledge of these orbiting spacecraft data characteristics improves the performance and interpretability of machine learning methods, which is essential for deriving scientific meaning. Building on these findings, we present a framework on incorporating physics knowledge into machine learning problems targeting semi-supervised classification for space physics data in planetary environments. These findings present a path forward for incorporating physical knowledge into space physics and planetary mission data analyses for scientific discovery.

description: We apply Feshbach-Krein-Schur renormalization techniques in the hierarchical Anderson model to establish a criterion on the single-site distribution which ensures exponential dynamical localization as well as positive inverse participation ratios and Poisson statistics of eigenvalues. Our criterion applies to all cases of exponentially decaying hierarchical hopping strengths and holds even for spectral dimension $d > 2$, which corresponds to the regime of transience of the underlying hierarchical random walk. This challenges recent numerical findings that the spectral dimension is significant as far as the Anderson transition is concerned.

description: A close partnership between people and partially autonomous machines has enabled decades of space exploration. But to further expand our horizons, our systems must become more capable. Increasing the nature and degree of autonomy - allowing our systems to make and act on their own decisions as directed by mission teams - enables new science capabilities and enhances science return. The 2011 Planetary Science Decadal Survey (PSDS) and on-going pre-Decadal mission studies have identified increased autonomy as a core technology required for future missions. However, even as scientific discovery has necessitated the development of autonomous systems and past flight demonstrations have been successful, institutional barriers have limited its maturation and infusion on existing planetary missions. Consequently, the authors and endorsers of this paper recommend that new programmatic pathways be developed to infuse autonomy, infrastructure for support autonomous systems be invested in, new practices be adopted, and the cost-saving value of autonomy for operations be studied.

description: The detection of an electron bunch exiting a strong magnetic field can prove challenging due to the small mass of the electron. If placed too far from a solenoid's entrance, a detector outside the magnetic field will be too small to reliably intersect with the exiting electron beam because the light electrons will follow the diverging magnetic field outside the solenoid. The TITAN group at TRIUMF in Vancouver, Canada, has made use of advances in the practice and precision of photochemical machining (PCM) to create a new kind of charge collecting detector called the "mesh detector." The TITAN mesh detector was used to solve the problem of trapped electron detection in the new Cooler PEnning Trap (CPET) currently under development at TITAN. This thin array of wires etched out of a copper plate is a novel, low profile, charge agnostic detector that can be made effectively transparent or opaque at the user's discretion.

description: Modulated martensites play an important role in magnetic shape memory alloys, because all functional properties are closely connected to the twin microstructure and the phase boundary. The nature of the modulated martensites is still unclear. One approach is the concept of adaptive martensite, which regards all modulated phases as nanotwinned microstructures. In this article, we use the Ni-Mn-based shape memory alloys as an example to show the geometric rationale behind this concept using analytic equations based on the phenomenological theory of martensite. This could enhance discussions about the implications of the adaptive martensite by showing the exact relations between the various unit cells used to describe the structure. We use the concept to discuss the compatibility at the habit plane, the nature of high-order twin boundaries and the dependence of the lattice constants on the different types of modulation.

description: To meet the ever-growing demand for a higher communicating rate and better communication quality, more and more small cells are overlaid under the macro base station (MBS) tier, thus forming the heterogeneous networks. Small cells can ease the load pressure of MBS but lack of the guarantee of performance. On the other hand, cooperation draws more and more attention because of the great potential of small cell densification. Some technologies matured in wired network can also be applied to cellular networks, such as Software-defined networking (SDN). SDN helps simplify the structure of multi-tier networks. And it's more reasonable for the SDN controller to implement cell coordination. In this paper, we propose a method to offload users from MBSs through small cell cooperation in heterogeneous networks. Association probability is the main indicator of offloading. By using the tools from stochastic geometry, we then obtain the coverage probabilities when users are associated with different types of base stations (BSs). All the cell association and cooperation are conducted by the SDN controller. Then on this basis, we compare the overall coverage probabilities, achievable rate and energy efficiency with and without cooperation. Numerical results show that small cell cooperation can offload more users from MBS tier. It can also increase the system's coverage performance. As small cells become denser, cooperation can bring more gains to the energy efficiency of the network.

description: We define solvable quantum mechanical systems on a Hilbert space spanned by bipartite ribbon graphs with a fixed number of edges. The Hilbert space is also an associative algebra, where the product is derived from permutation group products. The existence and structure of this Hilbert space algebra has a number of consequences. The algebra product, which can be expressed in terms of integer ribbon graph reconnection coefficients, is used to define solvable Hamiltonians with eigenvalues expressed in terms of normalized characters of symmetric group elements and degeneracies given in terms of Kronecker coefficients, which are tensor product multiplicities of symmetric group representations. The square of the Kronecker coefficient for a triple of Young diagrams is shown to be equal to the dimension of a sub-lattice in the lattice of ribbon graphs. This leads to an answer to the long-standing question of a combinatoric interpretation of the Kronecker coefficients. As an avenue to explore quantum supremacy and its implications for computational complexity theory, we outline experiments to detect non-vanishing Kronecker coefficients for hypothetical quantum realizations/simulations of these quantum systems. The correspondence between ribbon graphs and Belyi maps leads to an interpretation of these quantum mechanical systems in terms of quantum membrane world-volumes interpolating between string geometries.

description: The incompletely deciphered hieroglyphic script and language of the Maya constitutes the primary focus of the research project under discussion here, which is being carried out cooperatively by the Universities of Bonn and Göttingen. The project’s goal is to compile a text database and, on this basis, a dictionary of Classic Mayan. Approximately 10,000 text and image carriers have survived from the the time of the Maya culture’s fluorescence between A.D. 250 and 950, and their textual and iconographic information provide unique perspectives into the language, culture, and history of pre-Hispanic Maya society. To this day, however, the text and image carriers have yet to be systematically documented and comprehensively analyzed. Such efforts would permit a detailed and precise investigation of the Classic Mayan literary language, for instance by comparing text passages using co-text and co-occurrence analysis, correlating imagery with text passages, or registering the composition or function of a text carrier in the inscription and thus potentially elucidating ambiguous text passages. Until now, such systematic and cross-linked work with text, image, and information carriers was impossible, because the necessary technology did not yet exist in this field of research. Within the framework of this project, the text and image carriers will be systematically described according to uniform standards and the source material will be made machine-readable based on XML, thereby creating the foundation for compiling the dictionary.

description: The wave kinetic equation (WKE) describing drift-wave (DW) turbulence is widely used in studies of zonal flows (ZFs) emerging from DW turbulence. However, this formulation neglects the exchange of enstrophy between DWs and ZFs and also ignores effects beyond the geometrical-optics limit. We derive a modified theory that takes both of these effects into account, while still treating DW quanta ("driftons") as particles in phase space. The drifton dynamics is described by an equation of the Wigner-Moyal type, which is commonly known in the phase-space formulation of quantum mechanics. In the geometrical-optics limit, this formulation features additional terms missing in the traditional WKE that ensure exact conservation of the total enstrophy of the system, in addition to the total energy, which is the only conserved invariant in previous theories based on the WKE. Numerical simulations are presented to illustrate the importance of these additional terms. The proposed formulation can be considered as a phase-space representation of the second-order cumulant expansion, or CE2.

description: The “Text Database and Dictionary of Classic Mayan” project acquired a Breuckmann smartSCAN C5 structured-light scanner for high-resolution and three-dimensional documentation of Maya artefacts with inscriptions. Renderings of the stereolithographic mesh can be used to create (digital) line drawings for the project’s repository. This working paper exemplifies the workflow of creating a drawing on the basis of a mesh (rather than describing the scanning and mesh generation process themselves) in order to evaluate a best practice and define standards for the project.
