We are interested in dynamic scenarios where data is sampled progressively, and learning is done in an incremental rather than a batch mode. We seek efficient incremental algorithms for computing feature importance (FI). Permutation feature importance (PFI) is a well-established model-agnostic measure to obtain global FI based on feature marginalization of absent features. We propose an efficient, model-agnostic algorithm called iPFI to estimate this measure incrementally and under dynamic modeling conditions including concept drift. We prove theoretical guarantees on the approximation quality in terms of expectation and variance. To validate our theoretical findings and the efficacy of our approaches in incremental scenarios dealing with streaming data rather than traditional batch settings, we conduct multiple experimental studies on benchmark data with and without concept drift.}}, author = {{Fumagalli, Fabian and Muschalik, Maximilian and Hüllermeier, Eyke and Hammer, Barbara}}, issn = {{0885-6125}}, journal = {{Machine Learning}}, keywords = {{Artificial Intelligence, Software}}, number = {{12}}, pages = {{4863--4903}}, publisher = {{Springer Science and Business Media LLC}}, title = {{{Incremental permutation feature importance (iPFI): towards online explanations on data streams}}}, doi = {{10.1007/s10994-023-06385-y}}, volume = {{112}}, year = {{2023}}, } @inproceedings{48775, author = {{Fumagalli, Fabian and Muschalik, Maximilian and Hüllermeier, Eyke and Hammer, Barbara}}, booktitle = {{ESANN 2023 proceedings}}, location = {{Bruges (Belgium) and online}}, publisher = {{i6doc.com publ.}}, title = {{{On Feature Removal for Explainability in Dynamic Environments}}}, doi = {{10.14428/esann/2023.es2023-148}}, year = {{2023}}, } @inproceedings{52230, author = {{Fumagalli, Fabian and Muschalik, Maximilian and Kolpaczki, Patrick and Hüllermeier, Eyke and Hammer, Barbara}}, booktitle = {{NeurIPS 2023 - Advances in Neural Information Processing Systems}}, pages = {{11515----11551}}, publisher = {{Curran Associates, Inc.}}, title = {{{SHAP-IQ: Unified Approximation of any-order Shapley Interactions}}}, volume = {{36}}, year = {{2023}}, } @article{46248, author = {{Demir, Caglar and Wiebesiek, Michel and Lu, Renzhong and Ngonga Ngomo, Axel-Cyrille and Heindorf, Stefan}}, journal = {{ECML PKDD}}, location = {{Torino}}, title = {{{LitCQD: Multi-Hop Reasoning in Incomplete Knowledge Graphs with Numeric Literals}}}, year = {{2023}}, } @inproceedings{52341, author = {{Intveen, Julie and Hohwiller, Peter}}, location = {{Universität Paderborn}}, title = {{{The True Story of a Total Fake – Eine Untersuchung des didaktischen Potentials von Netflix‘ Inventing Anna}}}, year = {{2023}}, } @inproceedings{52340, author = {{Intveen, Julie}}, location = {{Universität Münster}}, title = {{{Fictions of Identity – A Didactic Exploration of TV Series}}}, year = {{2023}}, } @inproceedings{52339, author = {{Intveen, Julie}}, location = {{Universität Erfurt}}, title = {{{Fictions of Identity – A Didactic Approach to Serial Literacy}}}, year = {{2023}}, } @article{52336, author = {{Intveen, Julie}}, journal = {{Englisch betrifft uns}}, number = {{4}}, pages = {{17--21}}, title = {{{Chasing the American Dream: Chances and challenges of immigrant families – a media task}}}, year = {{2023}}, } @article{46548, abstract = {{The use of iron as a replacement for noble metals in photochemical and photophysical applications is challenging due to the typically fast deactivation of short-lived catalytically active states.

Requirements of multi-material construction involve adjustments to standard joining techniques.

This approach uses friction-induced heat to form customisable joining elements to join sheets for different boundary conditions, even for brittle cast materials. It is possible to react immediately to adapt to the joining process inline and reduce the amount of different joining elements. As the joining partner serve casting plates of the aluminium casting alloy EN AC–AlSi9, which is processed in the sand casting. Joining hypoeutectic AlSi alloys constitutes a challenge because the brittle character of these cause cracks in the joint during conventional mechanical joining. Furthermore, the friction-induced heat of the novel joining process causes a finer microstructure in the hypoeutectic AlSi9 casting alloy. In particular, the eutectic Si is more fine-grained, resulting in higher joint ductility. This study indicates the joining suitability of a hypoeutectic aluminium casting alloy in combination with adaptive manufactured additional joining elements.

Here, the low ductility of the AlSi alloys constitutes a challenge because their brittle nature causes cracks during the joining process. However, by using suitable solidification conditions, it is possible to achieve a microstructure with improved mechanical and joining properties. For this study, we used the twin-roll casting process (TRC) with water-cooled rollers to manufacture the hypoeutectic AlSi10Mg for the first time. Hereby, high solidification rates are realisable, which introduces a microstructure that is about four times finer than in the sand casting process. In particular, it is shown that a fine microstructure close to the modification with Na or Sr is achieved by the high solidification rate in the TRC process without using these elements. Based on this, the mechanical properties increase, and especially the ductility is enhanced.

The thermophysical properties of lubricants, and in particular the viscosity, at such extreme conditions have an important influence on the friction and wear behavior of a tribosystem. Accordingly, reliable lubricant property models are a prerequisite for accurate tribological simulations, e.g. elastohydrodynamic lubrication (EHL) simulations. Presently, the vast majority of experimental thermophysical property data are only available up to 1 GPa. Thus, reliable and robust models with strong extrapolation capabilities to higher pressure are required. In this work, viscosity measurements of squalane in a temperature range be tween 20 °C and 100 °C and pressures up to 1 GPa were carried out. Based on that data, a physical model for the viscosity was developed. The model is built by combining a molecular-based equation of state with the so-called entropy scaling approach. Finally, we demonstrate how this fluid property model can be favorably integrated in an EHL simulation by an application programming interface (API).

We derived a set of 36 relevant criteria from the literature and used them to evaluate a total of 46 static analysis tools complying with our inclusion and exclusion criteria - a representative set of mainly non-proprietary tools. The evaluation against the usability criteria in a multiple-raters approach shows that two thirds of the considered tools off er poor warning messages, while about three-quarters provide hardly any fix support. Furthermore, the integration of user knowledge is strongly neglected, which could be used for instance, to improve handling of false positives. Finally, issues regarding workflow integration and specialized user interfaces are revealed. These findings should prove useful in guiding and focusing further research and development in user experience for static code analyses.}}, author = {{Nachtigall, Marcus and Schlichtig, Michael and Bodden, Eric}}, booktitle = {{Software Engineering 2023}}, isbn = {{978-3-88579-726-5}}, keywords = {{Automated static analysis, Software usability}}, pages = {{95–96}}, publisher = {{Gesellschaft für Informatik e.V.}}, title = {{{Evaluation of Usability Criteria Addressed by Static Analysis Tools on a Large Scale}}}, year = {{2023}}, } @inbook{52660, abstract = {{Application Programming Interfaces (APIs) are the primary mechanism developers use to obtain access to third-party algorithms and services. Unfortunately, APIs can be misused, which can have catastrophic consequences, especially if the APIs provide security-critical functionalities like cryptography. Understanding what API misuses are, and how they are caused, is important to prevent them, eg, with API misuse detectors. However, definitions for API misuses and related terms in literature vary. This paper presents a systematic literature review to clarify these terms and introduces FUM, a novel Framework for API Usage constraint and Misuse classification. The literature review revealed that API misuses are violations of API usage constraints. To address this, we provide unified definitions and use them to derive FUM. To assess the extent to which FUM aids in determining and guiding the improvement of an API misuses detector’s capabilities, we performed a case study on the state-of the-art misuse detection tool CogniCrypt. The study showed that FUM can be used to properly assess CogniCrypt’s capabilities, identify weaknesses and assist in deriving mitigations and improvements.}}, author = {{Schlichtig, Michael and Sassalla, Steffen and Narasimhan, Krishna and Bodden, Eric}}, booktitle = {{Software Engineering 2023}}, isbn = {{978-3-88579-726-5}}, keywords = {{API misuses API usage constraints, classification framework, API misuse detection, static analysis}}, pages = {{105–106}}, publisher = {{Gesellschaft für Informatik e.V.}}, title = {{{Introducing FUM: A Framework for API Usage Constraint and Misuse Classification}}}, year = {{2023}}, }
