--- _id: '59483' abstract: - lang: eng text: Abstract. The assessment of mechanically joined connections, such as clinched connections, is usually conducted destructively. Applicable non-destructive testing methods like computed tomography are time-consuming and costly, or, like electrical resistance measurement, provide only a limited amount of information. A fast, non-destructive evaluation of the joints condition shall be made possible by using transient dynamic analysis (TDA). It is based on the introduction of sound waves and the evaluation of the response behavior after passing through the structure. This study focuses the application of TDA to clinched shear connections to evaluate the performance of the tactile measuring setup. Twenty-one series were investigated, covering variations in joining task, manufacturing and defect. The evaluation was carried out using machine learning to determine for which series characteristic signals may be detected. It was shown that a classification of the investigated specimens is possible, whereby the classification accuracy depends on the examined variation. Furthermore, the accuracy was evaluated as a function of frequency and results were concluded to identify the limits of the used measuring setup. author: - first_name: Gregor full_name: Reschke, Gregor last_name: Reschke - first_name: Alexander full_name: Brosius, Alexander last_name: Brosius citation: ama: 'Reschke G, Brosius A.

However, this information cannot be directly used for structural analyses, since it requires a discretization on micrometer level. Therefore, current failure theories do not directly account for such effects, but describe the behavior averaged over an entire specimen. This foundation in experimentally accessible loading conditions leads to purely theory based extension to more complex stress states without direct validation possibilities. This work aims at leveraging micro-scale simulations to obtain failure information under arbitrary loading conditions. The results are propagated to the meso-scale, enabling efficient structural analyses, by means of machine learning (ML). It is shown that the ML model is capable of correctly assessing previously unseen stress states and therefore poses an efficient tool of exploiting information from the micro-scale in larger simulations. author: - first_name: Johannes full_name: Gerritzen, Johannes id: '105344' last_name: Gerritzen orcid: 0000-0002-0169-8602 - first_name: Andreas full_name: Hornig, Andreas last_name: Hornig - first_name: Maik full_name: Gude, Maik last_name: Gude citation: ama: 'Gerritzen J, Hornig A, Gude M.

Recent advances in artificial intelligence, including learning approaches like reinforcement\r\nlearning and architectures like transformers and foundation models, combined with access to massive datasets, has created attractive\r\nopportunities to apply those data-hungry techniques to this problem. We argue that the focus on massive amounts of pre-collected\r\ndata, and the resulting learning paradigm, where humans demonstrate and robots learn in isolation, is overshadowing a specialized\r\narea of work we term Human-Interactive-Robot-Learning (HIRL). This paradigm, wherein robots and humans interact during the\r\nlearning process, is at the intersection of multiple fields (artificial intelligence, robotics, human-computer interaction, design and others)\r\nand holds unique promise. Using HIRL, robots can achieve greater sample efficiency (as humans can provide task knowledge through\r\ninteraction), align with human preferences (as humans can guide the robot behavior towards their expectations), and explore more\r\nmeaningfully and safely (as humans can utilize domain knowledge to guide learning and prevent catastrophic failures). This can result\r\nin robotic systems that can more quickly and easily adapt to new tasks in human environments. The objective of this paper is to\r\nprovide a broad and consistent overview of HIRL research and to guide researchers toward understanding the scope of HIRL, and\r\ncurrent open or underexplored challenges related to four themes — namely, human, robot learning, interaction, and broader context.\r\nThe paper includes concrete use cases to illustrate the interaction between these challenges and inspire further research according to\r\nbroad recommendations and a call for action for the growing HIRL community" article_type: original author: - first_name: 'Kim ' full_name: 'Baraka, Kim ' last_name: Baraka - first_name: Ifrah full_name: Idrees, Ifrah last_name: Idrees - first_name: Taylor Kessler full_name: Faulkner, Taylor Kessler last_name: Faulkner - first_name: Erdem full_name: Biyik, Erdem last_name: Biyik - first_name: Serena full_name: Booth, Serena last_name: Booth - first_name: Mohamed full_name: Chetouani, Mohamed last_name: Chetouani - first_name: Daniel H. full_name: Grollman, Daniel H. last_name: Grollman - first_name: Akanksha full_name: Saran, Akanksha last_name: Saran - first_name: Emmanuel full_name: Senft, Emmanuel last_name: Senft - first_name: Silvia full_name: Tulli, Silvia last_name: Tulli - first_name: Anna-Lisa full_name: Vollmer, Anna-Lisa last_name: Vollmer - first_name: Antonio full_name: Andriella, Antonio last_name: Andriella - first_name: Helen full_name: Beierling, Helen last_name: Beierling - first_name: Tiffany full_name: Horter, Tiffany last_name: Horter - first_name: Jens full_name: Kober, Jens last_name: Kober - first_name: Isaac full_name: Sheidlower, Isaac last_name: Sheidlower - first_name: Matthew E. full_name: Taylor, Matthew E. last_name: Taylor - first_name: Sanne full_name: van Waveren, Sanne last_name: van Waveren - first_name: Xuesu full_name: Xiao, Xuesu last_name: Xiao citation: ama: 'Baraka K, Idrees I, Faulkner TK, et al.

Yet, deep-learning-based models are only post-hoc and locally explainable. In contrast, learning Web Ontology Language (OWL) class expressions in Description Logics (DLs) is ante-hoc and globally explainable. However, state-of-the-art learners have two well-known lim-itations: scaling to large knowledge graphs and handling missing infor-mation. Here, we present a decision-tree-based learner (tDL) to learn Web Ontology Languages (OWLs) class expressions over large knowl-edge graphs, while imputing missing triples. Given positive and negative example individuals, tDL firstly constructs unique OWL expressions in .SHOIN from concise bounded descriptions of individuals. Each OWL class expression is used as a feature in a binary classification problem to represent input individuals. Thereafter, tDL fits a CART decision tree to learn Boolean decision rules distinguishing positive examples from nega-tive examples. A final OWL expression in.SHOIN is built by traversing the built CART decision tree from the root node to leaf nodes for each positive example. By this, tDL can learn OWL class expressions without exploration, i.e., the number of queries to a knowledge graph is bounded by the number of input individuals. Our empirical results show that tDL outperforms the current state-of-the-art models across datasets. Impor-tantly, our experiments over a large knowledge graph (DBpedia with 1.1 billion triples) show that tDL can effectively learn accurate OWL class expressions, while the state-of-the-art models fail to return any results. Finally, expressions learned by tDL can be seamlessly translated into natural language explanations using a pre-trained large language model and a DL verbalizer.' author: - first_name: Caglar full_name: Demir, Caglar last_name: Demir - first_name: Moshood full_name: Yekini, Moshood last_name: Yekini - first_name: Michael full_name: Röder, Michael last_name: Röder - first_name: Yasir full_name: Mahmood, Yasir last_name: Mahmood - first_name: Axel-Cyrille full_name: Ngonga Ngomo, Axel-Cyrille last_name: Ngonga Ngomo citation: ama: 'Demir C, Yekini M, Röder M, Mahmood Y, Ngonga Ngomo A-C.

This has also prompted the adoption of ensemble learning for the knowledge graph embedding (KGE) models in performing link prediction. Typical approaches to this end train multiple models as part of the ensemble, and the diverse predictions are then averaged. However, this approach has some significant drawbacks. For instance, the computational overhead of training multiple models increases latency and memory overhead. In contrast, model merging approaches offer a promising alternative that does not require training multiple models. In this work, we introduce model merging, specifically weighted averaging, in\r\nKGE models. Herein, a running average of model parameters from a training epoch onward is maintained and used for predictions. To address this, we additionally propose an approach that selectively updates the running average of the ensemble model parameters only when the generalization performance improves on a validation dataset. We evaluate these two different weighted averaging approaches on link prediction tasks, comparing the state-of-the-art benchmark ensemble approach. Additionally, we evaluate the weighted averaging approach considering literal-augmented KGE models and multi-hop query answering tasks as well. The results demonstrate that the proposed weighted averaging approach consistently improves performance across diverse evaluation settings." author: - first_name: Rupesh full_name: Sapkota, Rupesh id: '89326' last_name: Sapkota - first_name: Caglar full_name: Demir, Caglar last_name: Demir - first_name: Arnab full_name: Sharma, Arnab last_name: Sharma - first_name: Axel-Cyrille full_name: Ngonga Ngomo, Axel-Cyrille last_name: Ngonga Ngomo citation: ama: 'Sapkota R, Demir C, Sharma A, Ngonga Ngomo A-C.

E. Moore, C. D. Broad, and J. E. McTaggart. He received his BA in 1924, after which he worked for five years at the National Institute of Industrial Psychology. From 1929 to 1934, Wisdom was a Lecturer in the department of logic and metaphysics at the University of St Andrews and a colleague of G. F. Stout. After the publication of his book Interpretation and Analysis (1931) and five articles on “Logical Constructions” in Mind (1931–3), Wisdom became a Lecturer in Moral Sciences in Cambridge and a Fellow of Trinity College. This gave him the opportunity to gain first-hand knowledge of Wittgenstein’s philosophy. Since nothing by Wittgenstein but Tractatus appeared in print for decades, Wisdom’s publications of these years were—mistakenly—read as portents of the new ideas of Wittgenstein himself. The publication of Wittgenstein’s Philosophical Investigations in 1953 brought with it, among other things, the fall of Wisdom’s popularity.

The paper was unusually critical of Wittgenstein. It put the Cambridge analytic philosophy of Moore and Russell in a sharp opposition to the positivist philosophy of the Vienna Circle, in which Stebbing included Wittgenstein. Whereas the positivists were interested in analysing language, the Cambridge realists were analysing facts. To be more explicit, the analytic philosophers were engaged in directional analysis, which seeks to illuminate (to elucidate) the multiplicity of the analysed facts. In contrast, positivists aimed at a final analysis that proves that there are simples. Stebbing’s sympathies were clearly on the side of the Cambridge realists. The important implication of Stebbing’s paper was that it urged Wittgenstein to change the style of his philosophy, abandoning those points which allegedly connected him with the Vienna Circle. author: - first_name: Nikolay full_name: Milkov, Nikolay id: '357' last_name: Milkov citation: ama: 'Milkov N.

A recent and popular model is the Refined Consensus Model (RCM), which proposes a framework of dispositional competencies (personal PCK—pPCK) that influence more action-related competencies (enacted PCK—ePCK) and vice versa. However, descriptions of the internal structure of pPCK and possible knowledge domains that might develop independently are still limited, being either primarily theoretically motivated or strictly hierarchical and therefore of limited use, for example, for formative feedback and further development of the RCM. Meanwhile, a non-hierarchical differentiation for the ePCK regarding the plan-teach-reflect cycle has emerged. In this study, we present an exploratory computational approach to investigate pre-service teachers'' pPCK for a similar non-hierarchical structure using a large dataset of responses to a pPCK questionnaire (N=846). We drew on theoretical foundations and previous empirical findings to achieve interpretability by integrating this external knowledge into our analyses using the Computational Grounded Theory (CGT) framework. The results of a cluster analysis of the pPCK scores indicate the emergence of prototypical groups, which we refer to as competency profiles: (1) a group with low performance, (2) a group with relatively advanced competency in using pPCK to create instructional elements, (3) a group with relatively advanced competency in using pPCK to assess and analyze described instructional elements, and (4) a group with high performance. These groups show tendencies for certain language usage, which we analyze using a structural topic model in a CGT-inspired pattern refinement step. We verify these patterns by demonstrating the ability of a machine learning model to predict the competency profile assignments. Finally, we discuss some implications of the results for the further development of the RCM and their potential usability for an automated formative assessment.' article_type: original author: - first_name: Jannis full_name: Zeller, Jannis id: '99022' last_name: Zeller orcid: 0000-0002-1834-5520 - first_name: Josef full_name: Riese, Josef id: '429' last_name: Riese orcid: 0000-0003-2927-2619 citation: ama: 'Zeller J, Riese J.

Introducing causality into the modelling process offers a promising way to mitigate these challenges by enhancing predictive robustness. However, constructing an initial causal graph manually using domain knowledge is time-consuming, particularly in complex time series with numerous variables. To address this, causal discovery algorithms can provide a preliminary causal structure that domain experts can refine. This study investigates causal feature selection with domain knowledge using a data center system as an example. We use simulated time-series data to compare \r\ndifferent causal feature selection with traditional machine-learning feature selection methods. Our results show that predictions based on causal features are more robust compared to those derived from traditional methods. These findings underscore the potential of combining causal discovery algorithms with human expertise to improve machine learning applications." author: - first_name: David Ricardo full_name: Zapata Gonzalez, David Ricardo id: '105506' last_name: Zapata Gonzalez - first_name: Marcel full_name: Meyer, Marcel id: '105120' last_name: Meyer - first_name: Oliver full_name: Müller, Oliver id: '72849' last_name: Müller citation: ama: 'Zapata Gonzalez DR, Meyer M, Müller O.

Our method splits the state space into multiple windows that are predicted individually using a single model. Despite requiring only few data points (in some cases, our method can learn from a single full-state snapshot), it still achieves high accuracy and can predict the flow of PDEs over long time horizons. Moreover, we show how additional symmetries can be exploited to increase sample efficiency and to enforce equivariance. author: - first_name: Hans full_name: Harder, Hans id: '98879' last_name: Harder - first_name: Sebastian full_name: Peitz, Sebastian id: '47427' last_name: Peitz orcid: 0000-0002-3389-793X citation: ama: Harder H, Peitz S.

Daher werden Analysemethoden aus dem Bereich des Machine Learning (unsupervised) vorgeschlagen, welche im Gegensatz zu IRT-Modellen auch nicht-hierarchische inhaltliche Strukturen aufdecken können. Es werden Ergebnisse entsprechender Clusteranalysen sowie Analysepläne zur Unterstützung dieser auf Basis der authentischen Sprachproduktionen von Proband:innen mithilfe von Natural Language Processing vorgestellt. author: - first_name: Jannis full_name: Zeller, Jannis id: '99022' last_name: Zeller orcid: 0000-0002-1834-5520 - first_name: Josef full_name: Riese, Josef id: '429' last_name: Riese orcid: 0000-0003-2927-2619 citation: ama: 'Zeller J, Riese J.

To capture this in simulations, intricate models with a variety of parameters are typically used. The identification of values for such parameters is highly challenging and requires in depth understanding of the model itself. Machine learning (ML) is a promising approach for alleviating this challenge by directly predicting parameters based on experimental results. So far, this works mostly for purely artificial data. In this work, two approaches to generalize to experimental data are investigated: a sequential approach, leveraging understanding of the constitutive model and a direct, purely data driven approach. This is exemplary carried out for a highly non-linear strain rate dependent constitutive model for the shear behavior of FRP.The sequential model is found to work better on both artificial and experimental data. It is capable of extracting well suited parameters from the artificial data under realistic conditions. For the experimental data, the model performance depends on the composition of the experimental curves, varying between excellently suiting and reasonable predictions. Taking the expert knowledge into account for ML-model training led to far better results than the purely data driven approach. Robustifying the model predictions on experimental data promises further improvement.

Nonverbal signals play an important role for expressing mental states like understanding and confusion in these interactions. However, an individual's expressions may vary depending on other factors. In cases where these factors are unknown, machine learning methods that infer understanding from nonverbal cues become unreliable. Stress for example has been shown to affect human expression, but it is not clear from the current research how stress affects the expression of understanding.\r\nTo address this gap, we design a paradigm that induces understanding and confusion through game rule explanations. During the explanations, self-perceived understanding and confusion are annotated by the participants. A stress condition is also introduced to enable the investigation of changes in the expression of social signals under stress.\r\nWe conducted a study to validate the stress induction and participants reported a statistically significant increase in stress during the stress condition compared to the neutral control condition. \r\nAdditionally, feedback from participants shows that the paradigm is effective in inducing understanding and confusion. \r\nThis paradigm paves the way for further studies investigating social signals of understanding to improve human-machine explanation interactions for varying contexts." author: - first_name: Jonas full_name: Paletschek, Jonas id: '98941' last_name: Paletschek citation: ama: 'Paletschek J.

While semiconducting metal oxides such as In2O3 can monitor gas concentrations down to the ppm range, they often exhibit cross-sensitivity to other gases like H2O. In this study, we investigated whether cyclic optical illumination of a gas-sensitive In2O3 layer creates identifiable changes in a gas sensor´s electronic resistance that can be linked to H2 and H2O concentrations via machine learning. We exposed nanostructured In2O3 with a large surface area of 95 m2 g-1 to H2 concentrations (0-800 ppm) and relative humidity (0-70%) under cyclic activation utilizing blue light. The sensors were tested for 20 classes of gas combinations. A support vector machine achieved classification rates up to 92.0%, with reliable reproducibility (88.2 ± 2.7%) across five individual sensors using 10-fold cross-validation. Our findings suggest that cyclic optical activation can be used as a tool to classify H2 and H2O concentrations. article_type: original author: - first_name: 'Dominik ' full_name: 'Baier, Dominik ' last_name: Baier - first_name: 'Alexander ' full_name: 'Krüger, Alexander ' last_name: Krüger - first_name: 'Thorsten ' full_name: 'Wagner, Thorsten ' last_name: Wagner - first_name: Michael full_name: Tiemann, Michael id: '23547' last_name: Tiemann orcid: 0000-0003-1711-2722 - first_name: Christian full_name: Weinberger, Christian id: '11848' last_name: Weinberger citation: ama: 'Baier D, Krüger A, Wagner T, Tiemann M, Weinberger C.
