TODAY UnRAVeL Survey Lecture "What's New in UnRAVeL?"

von Tim Seppelt

Dear all, this is a reminder for Jürgen Giesl's talk on Improving Automatic Complexity Analysis of Probabilistic and Non-Probabilistic Integer Programs <https://www.unravel.rwth-aachen.de/cms/UnRAVeL/Das-Graduiertenkolleg/Aktuel…> taking place *today at 16:30* in room 5053.2 and on Zoom. Please find the details below. > We present an approach for automatic complexity analysis of integer > programs, based on an alternating modular inference of upper runtime > and size bounds for program parts. While our approach was originally > developed for non-probabilistic programs, we show how we extended it > to also infer upper bounds on the expected runtimes of probabilistic > integer programs automatically. > > Moreover, for the non-probabilistic case, we show how recent > techniques to improve automated termination analysis of integer > programs can be integrated into our approach for the inference of > runtime bounds. > > To evaluate its power, we implemented our approach in a new version of > our tool KoAT. Part of the programme of the research training group UnRAVeL is a series of introductory lectures on the topics of "randomness" and "uncertainty" in UnRAVeL’s research thrusts: Algorithms and complexity, verification, logic and languages, and their application scenarios. The main aim is to provide doctoral researchers as well as master students a broad overview of the subjects of UnRAVeL. Science undergoes continuous change and lives from the constant quest for novel and better results, which are presented at conferences and in journals. This year, 10 UnRAVeL professors will present some of their most recent research successes. Everyone interested, in particular doctoral researchers and master students, are invited to attend the UnRAVeL lecture series 2022 and engage in discussions with the researchers. The talks take place on Tuesdays, 16:30–18:00 in room 5053.2 in the ground floor of building E2. All events are hybrid.

Lehrstuhl Informatik 12 Thema: Discrete Tangent and Adjoint Sensitivity Analysis for Discontinuous Solutions of Hyperbolic Conservation Laws Abstract: We consider the discrete tangent and adjoint sensitivities computed via algorithmic differentiation of shock capturing numerical methods for hyperbolic conservation laws which are widely used for models of fluid dynamics such as those based on the Euler equations. For discontinuous solutions the discrete sensitivities do not generally converge to the correct sensitivities of the analytical solution as the discretization grid is refined because the analytical sensitivities are singular at the discontinuities of the solution. In this thesis we propose a convergent numerical approximation of the correct sensitivities of shock discontinuities in discontinuous solutions of hyperbolic conservations laws with respect to the parameters of the initial data. We compute the shock sensitivities by approximating the Rankine-Hugoniot condition taking into consideration the numerical viscosity of shock capturing numerical methods in a way that can be computed by algorithmic differentiation tools. The resulting discrete sensitivities enable for example the gradient-based parameter optimization of optimization problems constrained by a hyperbolic conservation law.

Etage, Informatikzentrum, Ahornstr. 55 Der Vortrag ist auch online über Zoom zu verfolgen: https://rwth.zoom.us/j/99709768339?pwd=MndDQ1MxMVdQWVpYZGpvYSt4bmdKdz09 Meeting-ID: 997 0976 8339, Kenncode: 975390 Referent: Matthias Volk, M.Sc. (Lehrstuhl Informatik 2) Thema: Dynamic Fault Trees: Semantics, Analysis and Applications Abstract: Safe and reliable systems are crucial in today’s society. Fault trees are a prominent and widely-used model to assess and improve the reliability of systems. Fault trees model how component failures propagate through a system and lead to a failure of the overall system. Dynamic fault trees (DFTs) are an extension of (static) fault trees and allow more modelling flexibility by introducing dynamic gates, spare management, functional dependencies and failure restrictions. In this presentation, we investigate dynamic fault trees in detail and consider three main aspects: (1) the precise semantics of DFTs, (2) the analysis of DFTs by model checking techniques, and (3) the application of DFTs, for example in the railway domain. We first specify the semantics of dynamic fault trees in terms of generalized stochastic Petri nets (GSPNs). We investigate multiple semantic questions resulting from the combination of DFT elements. Our resulting GSPN framework subsumes the major existing DFT semantics and allows to pinpoint their differences. Secondly, we present analysis techniques for DFTs based on probabilistic model checking. We introduce several (orthogonal) optimisation techniques which exploit symmetries, irrelevant failures and independent subtrees to improve the state-space generation times. We also show an approximation algorithm based on partial state-space exploration. All presented approaches are implemented in the open-source model checker Storm and evaluated on a DFT benchmark suite. The evaluation shows that our tool Storm-dft is state-of-the-art for DFT analysis. Third, we present the application of DFTs in the railway domain. The case study considers train routing options in railway station areas in terms of available infrastructure elements. We analyse how switch failures impact the potential train routes in a station and determine the most critical components. Es laden ein: die Dozentinnen und Dozenten der Informatik

TODAY UnRAVeL Survey Lecture "What's New in UnRAVeL?"

von Tim Seppelt

Dear all, this is a reminder for Michael Schaub's talk on Signal processing on graphs and complexes <https://www.unravel.rwth-aachen.de/go/id/tbarp?lidx=1> taking place *today at 16:30* in room 5053.2 and on Zoom. Please find the details below. > Graph signal processing (GSP) tries to device appropriate tools to > process signals supported on graphs by generalizing classical methods > from signal processing of time-series and images -- such as smoothing, > filtering and interpolation of signals supported on the nodes of a > graph. Typically, this involves leveraging the structure of the graph > as encoded in the spectral properties of the graph Laplacian. > In certain scenarios, such as traffic network analysis, the signals of > interest are however naturally defined on the edges of a graph, rather > than on the nodes. After a brief recap of the central ideas of GSP, we > examine why standard tools from GSP may not be suitable for the > analysis of such edge signals. More specifically, we discuss how the > underlying notion of 'signal vs noise' inherited from typically > considered variants of the graph Laplacian are not suitable when > dealing with edge signals that encode flows. To overcome this > limitation, we devise signal processing tools based on the > Hodge-Laplacian and the associated discrete Hodge Theory for > simplicial (and cellular) complexes.

Einladung: Informatik-Oberseminar Krishna Subramanian

von Subramanian, Krishna

+********************************************************************** * * * Einladung * * * * Informatik-Oberseminar * * * +********************************************************************** Zeit: Freitag, 8. April 2022, 12.15 Uhr Zoom URL: https://rwth.zoom.us/j/97644054920 Referent: Krishna Subramanian, M.Sc. Lehrstuhl für Informatik 10 Thema: Lowering the Barriers to Hypothesis-Driven Data Science Abstract: Data science is a frequent task in academia and industry. One common use of data science is to validate hypotheses, in which the analyst uses significance-based hypothesis testing to draw insights about a population distribution based on experimental data. Apart from data scientists, who are professionally trained in data science and are highly skilled, many non-professional analysts also carry out data analysis. These non-professionals, who we refer to as data workers, are domain experts who lack expertise in data science, such as academic researchers, project managers, and sales managers. Through interviews, observations, online surveys, and content analyses, we aim to understand data workers' workflows across important tasks in hypothesis testing: learning theoretical and practical statistics, selecting statistical procedures, using data science programming IDEs to experiment with ideas in source code, refine and refactor source code, and disseminating findings from an analysis.  We present our findings grouped into two steps when performing data science tasks: 1. Preparing to perform data science tasks: We discuss our findings about the impact of formal training on real-world statistical practice; trade-offs among information sources used for selecting statistical procedures; perceived complexity and uncertainty about statistical procedure selection; and reluctance among data workers to adopt alternative methods of analysis.  Based on the above findings, we present design recommendations and two artifacts to improve data workers' workflows. Our artifacts include Statsplorer, a web-based tool to help data workers kickstart analysis and learn about common issues in statistical practice, such as over-testing, overlooking assumptions, and selecting the appropriate test; and StatPlayground, an interactive simulation tool that can be used to self-learn or teach statistical concepts and statistical procedure selection.  2. Performing data science tasks: Our findings include an overview of data workers' workflows when performing hypothesis testing using programming IDEs, which follows an exploratory programming workflow; and a comparison of existing interfaces for data science programming, namely computational notebooks, scripts, and consoles, and a discussion of how well they support various steps in hypothesis testing.  To improve data workers' workflows when performing data science tasks, we contribute design recommendations and two artifacts. Our artifacts include StatWire, an experimental hybrid-programming interface that encourages data workers to write high-quality source code; and Tractus, an interactive visualization that can lower the cost of working with experimental source code. Based on our work, we present four takeaways that can be used by researchers, software developers, and educators to lower the barriers to hypothesis testing. --- Es laden ein: die Dozentinnen und Dozenten der Informatik

Lehrstuhl für Informatik 8 Thema: Topological Aspects of Maps Between Surfaces Abstract: We consider the generation of high-quality maps between 3D surfaces in the form of discrete homeomorphisms. Specifically, we address the topological issues underlying the construction of such maps, which have so far received comparably little attention in geometry processing research. We approach this task from two different angles: First, we propose a robust method for the construction of maps from sparse landmark correspondences, based on compatible layout embeddings. Our robust embedding strategy systematically searches for short, natural embeddings and therefore reliably avoids a range of sporadic topological initialization errors which can occur with previous heuristic approaches. Second, we introduce a novel algorithm to extract topological map descriptions from approximate, non-homeomorphic input maps. Such a purely abstract description of map topology may then be used to guide the construction of a proper homeomorphism. As our inference method is highly robust to a wide range of map defects and imperfect map representations, this effectively allows to delegate the difficult task of finding a natural map topology to specialized shape matching methods, which have grown increasingly capable. These advancements promote the further automation of map generation techniques in two regards: They vastly reduce the need for human supervision, and make the results of automatic shape matching methods accessible for topological initialization.

Einladung Informatik-Oberseminar: Linnea: A Compiler for Mapping

von Barthels, Henrik

+********************************************************************** * * * Einladung * * * * Informatik-Oberseminar * * * +********************************************************************** Zeit: Mittwoch, 23. März 2022, 15:00 Uhr Ort: Online (Zoom: https://umu.zoom.us/my/pauldj) Referent: Henrik Barthels, M.Sc. High-Performance and Automatic Computing Group, AICES. Thema: Linnea: A Compiler for Mapping Linear Algebra Problems onto High-Performance Kernel Libraries Abstract: The translation of linear algebra computations into efficient sequences of library calls is a non-trivial task that requires expertise in both linear algebra and high-performance computing. Almost all high-level languages and libraries for matrix computations (e.g., Matlab, Eigen) internally use optimized kernels such as those provided by BLAS and LAPACK; however, their translation algorithms are often too simplistic and thus lead to a suboptimal use of said kernels, resulting in significant performance losses. In order to combine the productivity offered by high-level languages, and the performance of low-level kernels, we are developing Linnea, a code generator for linear algebra problems. As input, Linnea takes a high-level description of a linear algebra problem; as output, it returns an efficient sequence of calls to high-performance kernels. Linnea uses a custom best-first search algorithm to find a first solution in less than a second, and increasingly better solutions when given more time. In 125 test problems, the code generated by Linnea almost always outperforms Matlab, Julia, Eigen and Armadillo, with speedups up to and exceeding 10x.
