So far, little is known about how an explainee, who lacks understanding of an issue, and an explainer, who has knowledge to fill the explainee's knowledge gap, actively shape an explanation process, and how their involvement relates to explanatory success in terms of maximizing the explainee's level of understanding. In this paper, we characterize explanations as dialogues in which explainee and explainer take turns to advance the explanation process. We build on an existing annotation scheme of ‘explanatory moves’ to characterize such turns, and manually annotate 362 dialogical explanations from the “Explain Like I'm Five” subreddit. Building on the annotated data, we compute correlations between explanatory moves and explanatory success, measured on a five-point Likert scale, in order to identify factors that are significantly correlated with explanatory success. Based on a qualitative analysis of these factors, we develop a conceptual model of the main factors that contribute to the success of explanatory dialogues."}],"publication":"Proceedings of the 26th ACM International Conference on Multimodal Interaction","department":[{"_id":"660"}],"type":"conference","date_created":"2024-08-30T07:55:36Z","publication_status":"published","date_updated":"2025-09-11T10:16:55Z","author":[{"full_name":"Booshehri, Meisam","last_name":"Booshehri","first_name":"Meisam"},{"first_name":"Hendrik","last_name":"Buschmeier","orcid":"0000-0002-9613-5713","full_name":"Buschmeier, Hendrik","id":"76456"},{"full_name":"Cimiano, Philipp","last_name":"Cimiano","first_name":"Philipp"}],"year":"2024","title":"A model of factors contributing to the success of dialogical explanations","doi":"10.1145/3678957.3685744","language":[{"iso":"eng"}]},{"date_created":"2024-09-03T07:39:14Z","department":[{"_id":"660"}],"type":"conference","publication":"Proceedings of the 25th Meeting of the Special Interest Group on Discourse and Dialogue","abstract":[{"lang":"eng","text":"Scripted dialogues such as movie and TV subtitles constitute a widespread source of training data for conversational NLP models.

This paper presents a quantitative analysis of such feedback phenomena in both subtitles and spontaneous conversations. Based on conversational data spanning eight languages and multiple genres, we extract lexical statistics, classifications from a dialogue act tagger, expert annotations and labels derived from a fine-tuned Large Language Model (LLM). Our main empirical findings are that (1) communicative feedback is markedly less frequent in subtitles than in spontaneous dialogues and (2) subtitles contain a higher proportion of negative feedback.

Also, the speakers’ dialogue role (explainer vs. explainee) appears to have a strong impact on turn-taking dynamics, as floor transitions that do not conform with the dialogue role tend to involve more effort, or floor management work.","lang":"eng"}],"publication":"Proceedings of the 28th Workshop on the Semantics and Pragmatics of Dialogue"},{"date_created":"2024-09-20T09:21:14Z","file":[{"date_created":"2024-10-03T16:03:33Z","creator":"hbuschme","content_type":"application/pdf","success":1,"file_id":"56313","access_level":"closed","file_size":2488042,"file_name":"klowait-etal-2024-DCM.pdf","date_updated":"2024-10-03T16:03:33Z","relation":"main_file"}],"department":[{"_id":"660"}],"type":"journal_article","publication":"Discourse & Communication","issue":"6","abstract":[{"text":"This study investigates the potential of using advanced conversational artificial intelligence (AI) to help people understand complex AI systems.

Our results reveal that an explainer-AI only truly functions as such when participants actively engage with it as a co-constructive agent. Both the interface’s spatial configuration and the asynchronous temporal nature of the explainer AI – combined with the users’ presuppositions about its role – contribute to the decision whether to treat the AI as a dialogical co-participant in the interaction.

As a remedy, the Shapley value (SV) is a well-known concept in explainable artificial intelligence (XAI) research for quantifying additive feature attributions of predictions. The model-specific TreeSHAP methodology solves the exponential complexity for retrieving exact SVs from tree-based models. Expanding beyond individual feature attribution, Shapley interactions reveal the impact of intricate feature interactions of any order. In this work, we present TreeSHAP-IQ, an efficient method to compute any-order additive Shapley interactions for predictions of tree-based models. TreeSHAP-IQ is supported by a mathematical framework that exploits polynomial arithmetic to compute the interaction scores in a single recursive traversal of the tree, akin to Linear TreeSHAP. We apply TreeSHAP-IQ on state-of-the-art tree ensembles and explore interactions on well-established benchmark datasets.","lang":"eng"}],"publication":"Proceedings of the AAAI Conference on Artificial Intelligence (AAAI)","issue":"13"},{"citation":{"mla":"Kolpaczki, Patrick, et al. “SVARM-IQ: Efficient Approximation of Any-Order Shapley Interactions through Stratification.” Proceedings of The 27th International Conference on Artificial Intelligence and Statistics (AISTATS), vol. 238, PMLR, 2024, pp. 3520–3528.","ama":"Kolpaczki P, Muschalik M, Fumagalli F, Hammer B, Huellermeier E.

In particular, extensions of the SV, such as the Shapley Interaction Index (SII), have been proposed as a measure to still benefit from the axiomatic basis of the SV. However, similar to the SV, their exact computation remains computationally prohibitive. Hence, we propose with SVARM-IQ a sampling-based approach to efficiently approximate Shapley-based interaction indices of any order. SVARM-IQ can be applied to a broad class of interaction indices, including the SII, by leveraging a novel stratified representation. We provide non-asymptotic theoretical guarantees on its approximation quality and empirically demonstrate that SVARM-IQ achieves state-of-the-art estimation results in practical XAI scenarios on different model classes and application domains.","lang":"eng"}],"date_created":"2024-07-18T09:39:14Z","department":[{"_id":"660"}],"type":"conference","author":[{"full_name":"Kolpaczki, Patrick","last_name":"Kolpaczki","first_name":"Patrick"},{"full_name":"Muschalik, Maximilian","first_name":"Maximilian","last_name":"Muschalik"},{"last_name":"Fumagalli","first_name":"Fabian","full_name":"Fumagalli, Fabian","id":"93420"},{"last_name":"Hammer","first_name":"Barbara","full_name":"Hammer, Barbara"},{"full_name":"Huellermeier, Eyke","last_name":"Huellermeier","first_name":"Eyke","id":"48129"}],"status":"public","title":"SVARM-IQ: Efficient Approximation of Any-order Shapley Interactions through Stratification","year":"2024","intvolume":" 238","date_updated":"2025-09-11T16:22:30Z","_id":"55311","language":[{"iso":"eng"}],"publisher":"PMLR","series_title":"Proceedings of Machine Learning Research","page":"3520–3528","volume":238,"user_id":"93420"},{"type":"conference","department":[{"_id":"660"}],"date_created":"2025-01-16T16:12:16Z","abstract":[{"lang":"eng","text":"The Shapley value (SV) is a prevalent approach of allocating credit to machine learning (ML) entities to understand black box ML models. Enriching such interpretations with higher-order interactions is inevitable for complex systems, where the Shapley Interaction Index (SII) is a direct axiomatic extension of the SV. While it is well-known that the SV yields an optimal approximation of any game via a weighted least square (WLS) objective, an extension of this result to SII has been a long-standing open problem, which even led to the proposal of an alternative index. In this work, we characterize higher-order SII as a solution to a WLS problem, which constructs an optimal approximation via SII and k-Shapley values (k-SII). We prove this representation for the SV and pairwise SII and give empirically validated conjectures for higher orders.

Most NLP methods are not sensitive to such variations. This may lead to unfair behavior of the methods, conveying negative bias towards dialect speakers. While previous work has studied dialect-related fairness for aspects like hate speech, other aspects of biased language, such as lewdness, remain fully unexplored. To fill this gap, we investigate performance disparities between dialects in the detection of five aspects of biased language and how to mitigate them. To alleviate bias, we present a multitask learning approach that models dialect language as an auxiliary task to incorporate syntactic and lexical variations. In our experiments with African-American English dialect, we provide empirical evidence that complementing common learning approaches with dialect modeling improves their fairness. Furthermore, the results suggest that multitask learning achieves state-of-the-art performance and helps to detect properties of biased language more reliably.","lang":"eng"}],"related_material":{"link":[{"relation":"software","url":"https://github.com/webis-de/acl24-dialect-aware-bias-detection"}]},"date_created":"2025-02-20T08:18:01Z","type":"conference","department":[{"_id":"600"},{"_id":"660"}]},{"date_updated":"2025-09-12T11:11:32Z","publication_status":"published","intvolume":" 1","title":"Time-bin entanglement in the deterministic generation of linear photonic cluster states","year":"2024","author":[{"full_name":"Bauch, David","first_name":"David","last_name":"Bauch"},{"full_name":"Köcher, Nikolas","first_name":"Nikolas","last_name":"Köcher","id":"79191"},{"last_name":"Heinisch","orcid":"0009-0006-0984-2097","first_name":"Nils","full_name":"Heinisch, Nils","id":"90283"},{"full_name":"Schumacher, Stefan","orcid":"0000-0003-4042-4951","first_name":"Stefan","last_name":"Schumacher","id":"27271"}],"publication_identifier":{"issn":["2835-0103"]},"doi":"10.1063/5.0214197","article_number":"036110","language":[{"iso":"eng"}],"abstract":[{"lang":"eng","text":"We theoretically investigate strategies for the deterministic creation of trains of time-bin entangled photons using an individual quantum emitter described by a Λ-type electronic system.

This allows the generation of high-quality single photons without the need of complex laser stray light suppression or careful spectral filtering. In the present work, we extend this promising method to quantum emitters, specifically semiconductor quantum dots, inside a resonant optical cavity. A significant advantage of the SUPER scheme is identified in that it eliminates re-excitation of the quantum emitter by suppressing photon emission during the excitation cycle. This, in turn, leads to almost ideal single-photon purity, overcoming a major factor typically limiting the quality of photons generated with quantum emitters in high-quality cavities. We further find that for cavity-mediated biexciton emission of degenerate photon pairs, the SUPER scheme leads to near-perfect biexciton initialization with very high values of polarization entanglement of emitted photon pairs.\r\n \r\n \r\n \r\n \r\n Published by the American Physical Society\r\n 2024\r\n \r\n \r\n ","lang":"eng"}],"date_created":"2025-09-12T11:16:31Z","department":[{"_id":"15"},{"_id":"170"},{"_id":"297"},{"_id":"35"},{"_id":"230"},{"_id":"429"},{"_id":"27"}],"type":"journal_article","author":[{"full_name":"Heinisch, Nils","last_name":"Heinisch","orcid":"0009-0006-0984-2097","first_name":"Nils","id":"90283"},{"full_name":"Köcher, Nikolas","first_name":"Nikolas","last_name":"Köcher","id":"79191"},{"full_name":"Bauch, David","last_name":"Bauch","first_name":"David"},{"full_name":"Schumacher, Stefan","orcid":"0000-0003-4042-4951","first_name":"Stefan","last_name":"Schumacher","id":"27271"}],"publication_identifier":{"issn":["2643-1564"]},"title":"Swing-up dynamics in quantum emitter cavity systems: Near ideal single photons and entangled photon pairs","year":"2024","intvolume":" 6","date_updated":"2025-09-12T11:18:05Z","publication_status":"published","language":[{"iso":"eng"}],"article_number":"L012017","doi":"10.1103/physrevresearch.6.l012017"},{"citation":{"mla":"Schneider, Tobias, et al. “Topological Edge and Corner States in Coupled Wave Lattices in Nonlinear Polariton Condensates.” Nanophotonics, vol. 13, no. 4, Walter de Gruyter GmbH, 2024, pp. 509–18, doi:10.1515/nanoph-2023-0556.","ama":"Schneider T, Gao W, Zentgraf T, Schumacher S, Ma X.

For the specific system of a driven-dissipative exciton polariton system we show that in such potential chains, different types of edge states can form. For resonant optical excitation, we further find that the optical nonlinearity leads to a multistability of different edge states. This includes topologically protected edge states evolved directly from individual linear eigenstates as well as additional edge states that originate from nonlinearity-induced localization of bulk states. Extending the system into two dimensions (2D) by stacking horizontal DW chains in the vertical direction, we also create 2D multi-wave lattices. In such 2D lattices multiple Su–Schrieffer–Heeger (SSH) chains appear along the vertical direction. The combination of DW chains in the horizonal and SSH chains in the vertical direction then results in the formation of higher-order topological insulator corner states.

Since automatic affect recognition can be used in sensitive applications, such as healthcare and education, it is crucial to understand how models arrive at their decisions. Interpretability of machine learning models is the goal of the emerging research area of Explainable AI (explainable AI (XAI)). This scoping review aims to survey the field of audiovisual affective machine learning to identify how XAI is applied in this domain. We first provide an overview of XAI concepts relevant to affective computing. Next, following the recommended PRISMA guidelines, we perform a literature search in the ACM, IEEE, Web of Science and PubMed databases. After systematically reviewing 1190 articles, a final set of 65 papers is included in our analysis. We quantitatively summarize the scope, methods and evaluation of the XAI techniques used in the identified papers. Our findings show encouraging developments for using XAI to explain models in audiovisual affective computing, yet only a limited set of methods are used in the reviewed works. Following a critical discussion, we provide recommendations for incorporating interpretability in future work for affective machine learnin","lang":"eng"}]}]
