For example, in a citation network, nodes representing \"Paper\" or \"Author\" may include attributes like keywords or affiliations. A critical machine learning task on these graphs is node classification, which is useful for applications such as fake news detection, corporate risk assessment, and molecular property prediction. Although Heterogeneous Graph Neural Networks (HGNNs) perform well in these contexts, their predictions remain opaque. Existing post-hoc explanation methods lack support for actual node features beyond one-hot encoding of node type and often fail to generate realistic, faithful explanations. To address these gaps, we propose DiGNNExplainer, a model-level explanation approach that synthesizes heterogeneous graphs with realistic node features via discrete denoising diffusion. In particular, we generate realistic discrete features (e.g., bag-of-words features) using diffusion models within a discrete space, whereas previous approaches are limited to continuous spaces. We evaluate our approach on multiple datasets and show that DiGNNExplainer produces explanations that are realistic and faithful to the model's decision-making, outperforming state-of-the-art methods."}],"citation":{"ieee":"P.

Specifically, we examine three linguistic cues related to cognitive load and hypothesised to correlate with listener understanding: the information value (operationalised with surprisal) and syntactic complexity of the speaker's utterances, and the variation in the listener's interactive gaze behaviour. Based on statistical analyses of the MUNDEX corpus of face-to-face dialogic board game explanations, we find that individual cues vary with the listener's level of understanding. Listener states (‘Understanding’, ‘Partial Understanding’, ‘Non-Understanding’ and ‘Misunderstanding’) were self-annotated by the listeners using a retrospective video-recall method. The results of a subsequent classification experiment, involving two off-the-shelf classifiers and a fine-tuned German BERT-based multimodal classifier, demonstrate that prediction of these four states of understanding is generally possible and improves when the three linguistic cues are considered alongside textual features."}],"publisher":"ELRA","_id":"64914","page":"11368-11378","user_id":"76456","conference":{"end_date":"2026-05-16","start_date":"2026-05-11","name":"15th Biennial Language Resources and Evaluation Conference","location":"Palma, Mallorca, Spain"},"status":"public","place":"Palma, Mallorca, Spain","oa":"1","citation":{"apa":"Wang, Y., Türk, O., Grimminger, A., &#38; Buschmeier, H.

With both an algebraic interpretation via the intersection of a polynomial with a set of lines, and a geometric interpretation via a (q+1)-set possessing an internal nucleus, the concepts have proved their usefulness as a new way to view various long-standing problems, and have applications in areas such as Kakeya sets. In this paper, by exploiting connections with diverse areas including the theory of algebraic curves, cyclotomy and the enumeration of irreducible polynomials, we establish new results and resolve various Open Problems of Li and Pott. We prove geometric results which shed new light on the relationship between intersection distribution and projective equivalence of polynomials, and algebraic results which describe and characterise the degree of Sf - the index of the largest non-zero entry in the intersection distribution of f. We provide new insights into the non-hitting spectrum, and show the limitations of the non-hitting index as a tool for characterisation. Finally, the benefits provided by the connections to other areas are evidenced in two short new proofs of the cubic case.

However, integrating these discounted sales into future demand forecasts presents a significant challenge. This study investigates the effectiveness of incorporating a fixed share of these sales as \\textit{regular} demand into the forecast, as commonly applied in practice. We employ a two-step regression approach on data from a major European grocery retailer, covering over 1,700 products across 676 stores. We reveal that forecasts underestimate actual demand for most SKUs when discounted sales occur. This residual uplift effect is significantly influenced by the number of sales at reduced prices. Our findings underscore the necessity for more precise approaches to integrate discounted sales into demand forecasts, thereby preventing excess inventory and the associated economic and environmental impacts of spoilage in the grocery sector."}],"file":[{"creator":"jbrenker","date_created":"2026-03-02T13:01:09Z","relation":"main_file","date_updated":"2026-03-02T13:01:09Z","file_name":"2602.04464v1.pdf","access_level":"closed","file_size":258211,"file_id":"64811","success":1,"content_type":"application/pdf"}],"date_created":"2026-03-02T13:00:32Z","type":"preprint","year":"2026","title":"Discounted Sales of Expiring Perishables: Challenges for Demand Forecasting in Grocery Retail Practice","author":[{"first_name":"David","last_name":"Winkelmann","full_name":"Winkelmann, David"},{"full_name":"Elbracht, Theresa","first_name":"Theresa","last_name":"Elbracht"},{"last_name":"Brenker","first_name":"Jonas Maximilian","full_name":"Brenker, Jonas Maximilian","id":"122957"},{"full_name":"Gerzen, Arnold","last_name":"Gerzen","first_name":"Arnold"}],"publication_status":"published","date_updated":"2026-05-07T15:29:50Z","main_file_link":[{"url":"https://arxiv.org/pdf/2602.04464","open_access":"1"}],"language":[{"iso":"eng"}]},{"abstract":[{"lang":"eng","text":"Traditional dyadic customer-provider interactions are being shifted to polyadic interactions involving diverse participants in digital service ecosystems. Especially, artificial intelligence (AI) is increasingly integrated into these ecosystems, so that they comprise non-human participants (e.g., AI-based chatbots)—fundamentally altering the nature of value (co-)creation. While existing literature examines human-to-human interactions, knowledge of service interactions between human actors and AI-based systems is still underexplored. To address this research gap, we develop a taxonomy, comprising six iterations, that explores the peculiarities of AI as either a resource or a (non-human) agent in digital service ecosystems. We evaluate our taxonomy using a multiple case study and derive the four archetypes of AI in digital service ecosystems: (1) discriminative experience enhancer, (2) protective ecosystem orchestrator, (3) ecosystem innovation companion, and (4) personalized service composer. Our results extend the knowledge on service science by showing how AI-based systems—discriminative or generative, and focusing on the interaction in the ecosystem or the individual service encounter—assume the role of resources and non-human agents. Researchers and practitioners can utilize our results to augment their ecosystems with AI.</jats:p>"}],"issue":"1","publication":"Electronic Markets","type":"journal_article","date_created":"2026-03-07T12:45:48Z","publication_status":"published","date_updated":"2026-05-09T14:42:19Z","intvolume":"        36","title":"Artificial intelligence in digital service ecosystems—Towards a taxonomy and archetypes","year":"2026","author":[{"full_name":"Hansmeier, Philipp","last_name":"Hansmeier","first_name":"Philipp","id":"55603"},{"full_name":"Schäfer, Jannika Marie","last_name":"Schäfer","first_name":"Jannika Marie","id":"74374"},{"id":"64394","full_name":"zur Heiden, Philipp","first_name":"Philipp","last_name":"zur Heiden"}],"publication_identifier":{"issn":["1019-6781","1422-8890"]},"doi":"10.1007/s12525-026-00879-y","article_number":"22","main_file_link":[{"url":"https://link.springer.com/article/10.1007/s12525-026-00879-y","open_access":"1"}],"language":[{"iso":"eng"}],"citation":{"short":"P.

We review in particular our work on both time- and frequency-domain approaches and give an outlook on how these architectures can be extended to include further signal processing tasks such as equalization. Optically triggered track-and-hold amplifiers are reported with an equivalent jitter below 80 fs rms in a signal frequency range from 20 GHz to 70 GHz. Frequency-domain architectures implementing optical arbitrary waveform measurement up to signal bandwidths of 610 GHz are also shown. Finally, an architecture allowing the deserialization and equalization of PAM4 signals is introduced and modeled for operation in 400 Gb/s links.","lang":"eng"}],"publication":"Electronic-Photonic Integrated Systems for Ultrafast Signal Processing","type":"book_chapter","department":[{"_id":"58"},{"_id":"623"}],"date_created":"2026-04-30T06:07:38Z","publication_status":"published","date_updated":"2026-05-11T07:56:04Z","year":"2026","title":"Ultra-Broadband Photonically Assisted Analog-to-Digital-Converters","author":[{"first_name":"Jeremy","last_name":"Witzens","full_name":"Witzens, Jeremy"},{"full_name":"Drayss, Daniel","last_name":"Drayss","first_name":"Daniel"},{"full_name":"Fang, Dengyang","last_name":"Fang","first_name":"Dengyang"},{"full_name":"Moscoso Mártir, Alvaro","first_name":"Alvaro","last_name":"Moscoso Mártir"},{"full_name":"Müller, Juliana","last_name":"Müller","first_name":"Juliana"},{"id":"44271","first_name":"Maxim","orcid":"0000-0003-2699-9839","last_name":"Weizel","full_name":"Weizel, Maxim"},{"full_name":"Zazzi, Andrea","first_name":"Andrea","last_name":"Zazzi"},{"last_name":"Freude","first_name":"Wolfgang","full_name":"Freude, Wolfgang"},{"first_name":"Christian","last_name":"Koos","full_name":"Koos, Christian"},{"last_name":"Randel","first_name":"Sebastian","full_name":"Randel, Sebastian"},{"full_name":"Scheytt, J.

However, in such photonic integrated circuits (PICs), the photonic components are placed very close to each other on the chip, resulting in thermal crosstalk which degrades the system performance. Air-filled oxide and deep trench designs have proven to be very effective in mitigating the thermal crosstalk for various frequently deployed photonic devices like Mach-Zehnder modulators (MZMs), ring resonators, optical switches, and photodetectors designed on a standard silicon-on-insulator (SOI) platform.

Die Daten werden inhaltsanalytisch sowie typenbildend ausgewertet, um das Verständnis und die Bedeutsamkeit in der jeweiligen Phase, längsschnittliche Entwicklungen sowie das Verhältnis von Verständnis und Bedeutsamkeit herauszuarbeiten. Die Befunde zeigen, dass die Verständnisse von Forschendem Lernen sowohl im Referendariat als auch im Berufseinstieg variieren. Zudem ist das Konzept – laut Schilderungen der Befragten – durchaus bedeutsam für ihre Lern- und Handlungspraxis, jedoch nicht für alle und in unterschiedlich ausgeprägter Form. Die Typenbildung verdeutlicht, dass die fehlende Bedeutsamkeit Forschenden Lernens mit Fehlkonzepten einhergeht und eine höhere Bedeutsamkeit erkennbar ist, wenn Adaptionsleistungen hinsichtlich des Konzepts vorgenommen werden. Insgesamt ist im Sinne der Auffassung als Professionsüberzeugung die Anbahnung einer forschenden Grundhaltung bei einigen Befragten erkennbar. Implikationen für eine künftige Hochschulbildung ergeben sich u. a. mit Blick auf die Unterstützung von Studierenden bei Adaptionsleistungen für die (jeweilige) Praxis.","lang":"ger"}],"publication":"Zeitschrift für Bildungsforschung"},{"department":[{"_id":"54"},{"_id":"1063"}],"type":"conference","keyword":["mixture models","meeting processing","diarization","source separation"],"date_created":"2026-05-11T14:20:48Z","abstract":[{"text":"Sound capture by microphone arrays opens the possibility to exploit spatial, in addition to spectral, information for diarization and signal enhancement, two important tasks in meeting transcription. However, there is no one-to-one mapping of positions in space to speakers if speakers move. Here, we address this by proposing a novel joint spatial and spectral mixture model, whose two submodels are loosely coupled by modeling the relationship between speaker and position index probabilistically. Thus, spatial and spectral information can be jointly exploited, while at the same time allowing for speakers speaking from different positions. Experiments on the LibriCSS data set with simulated speaker position changes show great improvements over tightly coupled subsystems.","lang":"eng"}],"publication":"ICASSP 2026 - 2026 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP)","doi":"10.1109/icassp55912.2026.11463540","language":[{"iso":"eng"}],"main_file_link":[{"open_access":"1","url":"https://arxiv.org/pdf/2601.16077"}],"date_updated":"2026-05-15T08:17:25Z","author":[{"last_name":"Meise","first_name":"Adrian Tobias","full_name":"Meise, Adrian Tobias","id":"79268"},{"id":"44393","first_name":"Tobias","last_name":"Cord-Landwehr","full_name":"Cord-Landwehr, Tobias"},{"id":"40767","first_name":"Christoph","last_name":"Boeddeker","full_name":"Boeddeker, Christoph"},{"first_name":"Marc","last_name":"Delcroix","full_name":"Delcroix, Marc"},{"full_name":"Nakatani, Tomohiro","last_name":"Nakatani","first_name":"Tomohiro"},{"full_name":"Haeb-Umbach, Reinhold","first_name":"Reinhold","last_name":"Haeb-Umbach","id":"242"}],"title":"Loose Coupling of Spectral and Spatial Models for Multi-Channel Diarization and Enhancement of Meetings in Dynamic Environments","year":"2026","oa":"1","external_id":{"arxiv":["https://arxiv.org/abs/2601.16077"]},"project":[{"_id":"52","name":"Computing Resources Provided by the Paderborn Center for Parallel Computing"}],"citation":{"apa":"Meise, A.

Primarily due to the digitalization of society, students have potentially greater access to a wider range of resources such as internet search engines, learning platforms, educational videos, and Generative AI. This study investigates the role of the mathematics textbook in comparison to other resources within students’ self-regulated learning practices. Data were collected via a survey of 1101 German secondary students, representing three school types (\r\n                    <jats:italic>Gymnasium</jats:italic>\r\n                    ,\r\n                    <jats:italic>Gesamtschule</jats:italic>\r\n                    ,\r\n                    <jats:italic>Realschule</jats:italic>\r\n                    ) and three grade levels (6, 9, and upper secondary). The questionnaire assessed the frequency of resource use in and outside class, reasons and purposes of use, and resource-based strategies when facing learning challenges outside class. Results show that the printed mathematics textbook is the most frequently used resource both in class and outside class. The textbook remains the most relevant resource for key purposes, such as an aid for doing homework and preparing for tests and exams. However, its dominance diminishes with age: in upper secondary school, students increasingly rely on self-created notes, and online resources. Correlation analyses reveal moderate to strong links between in-class and out-of-class use, suggesting an association between resource use and classroom culture. The findings underscore the textbook’s enduring centrality as a foundational, trusted resource within a dynamic and increasingly diverse learning environment. This study calls for pedagogical approaches that integrate textbooks more intentionally within broader resource systems, supporting students’ agency and strategic resource selection in an era of digital abundance.\r\n                  </jats:p>","lang":"eng"}],"date_created":"2026-05-17T14:32:31Z","department":[{"_id":"360"}],"keyword":["mathematics","textbooks","userstudy","resources","digital resources","students","secondary eduction"],"type":"journal_article"}]
