These models are costly to run with respect to computation and memory requirements. In this work, we propose to build a specialized low-resource classifier for classes pre-defined using text, using a two-stage procedure consisting of zero-shot data set pruning and model compression. First, relevant in-domain data is selected from a source dataset using class label embeddings obtained from a pre-trained CLAP model. This data is then used to distill the audio encoder of a CLAP model. The proposed compression method produces compact audio encoders with slightly reduced accuracy. Note that neither labeled nor unlabeled in-domain audio data is required for its development. We verify by cross-dataset tests that the resulting classifiers are indeed specialized to their task.","lang":"eng"}],"publication":"Proceedings of the 16th ITG Conference on Speech Communication","user_id":"62152","editor":[{"full_name":"Möller, Sebastian","first_name":"Sebastian","last_name":"Möller"},{"full_name":"Gerkmann, Timo","last_name":"Gerkmann","first_name":"Timo"},{"last_name":"Kolossa","first_name":"Dorothea","full_name":"Kolossa, Dorothea"}],"page":"76-80","_id":"62163","status":"public","conference":{"location":"Berlin","start_date":"2025-09-24","name":"16th ITG Conference on Speech Communication","end_date":"2025-09-26"},"place":"Berlin","quality_controlled":"1","project":[{"name":"WestAI - AI Service Center West","_id":"512"}],"citation":{"mla":"Werning, Alexander, and Reinhold Häb-Umbach. “A Fully Zero-Shot Approach to Obtaining Specialized and Compact Audio Tagging Models.” <i>Proceedings of the 16th ITG Conference on Speech Communication</i>, edited by Sebastian Möller et al., 2025, pp. 76–80.","bibtex":"@inproceedings{Werning_Häb-Umbach_2025, place={Berlin}, title={A Fully Zero-Shot Approach to Obtaining Specialized and Compact Audio Tagging Models}, booktitle={Proceedings of the 16th ITG Conference on Speech Communication}, author={Werning, Alexander and Häb-Umbach, Reinhold}, editor={Möller, Sebastian and Gerkmann, Timo and Kolossa, Dorothea}, year={2025}, pages={76–80} }","ama":"Werning A, Häb-Umbach R.

It is therefore necessary to compress and tune the models for the specific target task and hardware. This is commonly achieved by distilling the audio model, the teacher, to a small target model, the student. However, this approach can be improved by prepending a dataset pruning stage and training the teacher on the pruned data set only, which contains examples relevant to the target task. Recently, CLAP models have emerged that embed audio and text examples in a common embedding space. We use the audio embeddings of the CLAP model for the above pruning stage, which is realized using a domain classifier. After knowledge distillation, the student is eventually fine-tuned on some data from the target domain. The CLAP architecture combines text and audio embedding spaces, which allows to search for data given only a textual description, such as a class label. We show how this can help data pruning.","lang":"eng"}],"publication":"Proceedings of DAS|DAGA 2025","type":"conference","department":[{"_id":"54"}],"date_created":"2025-05-14T13:18:10Z","publication_status":"published","date_updated":"2025-11-28T13:21:13Z","year":"2025","title":"Distilling Efficient Audio Models using Data Pruning with CLAP","publication_identifier":{"unknown":["978-3-939296-23-2"]},"author":[{"first_name":"Alexander","last_name":"Werning","full_name":"Werning, Alexander","id":"62152"},{"id":"242","full_name":"Häb-Umbach, Reinhold","first_name":"Reinhold","last_name":"Häb-Umbach"}],"corporate_editor":["Deutsche Gesellschaft für Akustik e.V.

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.","lang":"eng"}],"publication":"Lecture Notes in Computer Science","doi":"10.1007/978-3-032-06066-2_29","language":[{"iso":"eng"}],"publication_status":"published","date_updated":"2025-11-28T14:57:39Z","title":"Tree-Based OWL Class Expression Learner over Large Graphs","year":"2025","publication_identifier":{"issn":["0302-9743","1611-3349"],"isbn":["9783032060655","9783032060662"]},"author":[{"last_name":"Demir","first_name":"Caglar","full_name":"Demir, Caglar"},{"last_name":"Yekini","first_name":"Moshood","full_name":"Yekini, Moshood"},{"first_name":"Michael","last_name":"Röder","full_name":"Röder, Michael"},{"full_name":"Mahmood, Yasir","first_name":"Yasir","last_name":"Mahmood"},{"last_name":"Ngonga Ngomo","first_name":"Axel-Cyrille","full_name":"Ngonga Ngomo, Axel-Cyrille"}]},{"date_updated":"2025-11-28T15:36:57Z","publication_status":"published","year":"2025","title":"Assessing Natural Language Explanations of Relational Graph Neural Networks","status":"public","author":[{"first_name":"Stefan","last_name":"Heindorf","orcid":"0000-0002-4525-6865","full_name":"Heindorf, Stefan","id":"11871"},{"full_name":"Neib, Daniel","last_name":"Neib","first_name":"Daniel"}],"doi":"10.1145/3746252.3760918","user_id":"11871","publisher":"ACM","_id":"62707","language":[{"iso":"eng"}],"publication":"Proceedings of the 34th ACM International Conference on Information and Knowledge Management","citation":{"bibtex":"@inproceedings{Heindorf_Neib_2025, title={Assessing Natural Language Explanations of Relational Graph Neural Networks}, DOI={<a href=\"https://doi.org/10.1145/3746252.3760918\">10.1145/3746252.3760918</a>}, booktitle={Proceedings of the 34th ACM International Conference on Information and Knowledge Management}, publisher={ACM}, author={Heindorf, Stefan and Neib, Daniel}, year={2025} }","ama":"Heindorf S, Neib D.

However, retraining LLMs is computationally expensive. Therefore, knowledge editing techniques are crucial for maintaining current information and correcting erroneous assertions within pre-trained models. Current benchmarks for knowledge editing primarily focus on recalling edited facts, often neglecting their logical consequences. To address this limitation, we introduce a new benchmark designed to evaluate how knowledge editing methods handle the logical consequences of a single fact edit. Our benchmark extracts relevant logical rules from a knowledge graph for a given edit. Then, it generates multi-hop questions based on these rules to assess the impact on logical consequences. Our findings indicate that while existing knowledge editing approaches can accurately insert direct assertions into LLMs, they frequently fail to inject entailed knowledge. Specifically, experiments with popular methods like ROME and FT reveal a substantial performance gap, up to 24%, between evaluations on directly edited knowledge and on entailed knowledge. This highlights the critical need for semantics-aware evaluation frameworks in knowledge editing.","lang":"eng"}],"publication":"Proceedings of the 24th International Semantic Web Conference (ISWC 2025)","department":[{"_id":"574"}],"keyword":["dice sailproject moteu kouagou zahera ngonga"],"type":"conference","date_created":"2025-08-27T13:17:55Z"},{"publication_status":"published","date_updated":"2025-12-02T05:44:54Z","author":[{"full_name":"Meschede, Henning","orcid":"0000-0002-1538-089X","first_name":"Henning","last_name":"Meschede","id":"86954"},{"full_name":"Knorr, Lukas","last_name":"Knorr","first_name":"Lukas","id":"90391"},{"first_name":"Antonio","last_name":"Piacentino","full_name":"Piacentino, Antonio"},{"first_name":"Natasa","last_name":"Markovska","full_name":"Markovska, Natasa"},{"full_name":"Duic, Neven","last_name":"Duic","first_name":"Neven"}],"publication_identifier":{"issn":["0360-5442"]},"status":"public","title":"Integrated and demand-responsive energy futures in the context of sustainable development of energy systems","year":"2025","user_id":"90391","doi":"10.1016/j.energy.2025.139453","_id":"62731","language":[{"iso":"eng"}],"publisher":"Elsevier BV","article_number":"139453","citation":{"chicago":"Meschede, Henning, Lukas Knorr, Antonio Piacentino, Natasa Markovska, and Neven Duic. “Integrated and Demand-Responsive Energy Futures in the Context of Sustainable Development of Energy Systems.” <i>Energy</i>, 2025. <a href=\"https://doi.org/10.1016/j.energy.2025.139453\">https://doi.org/10.1016/j.energy.2025.139453</a>.","short":"H.

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.","lang":"eng"}],"publication":"Proceedings of the Thirteenth International Conference on Knowledge Capture(K-CAP 2025)","keyword":["Knowledge Graphs","Embeddings","Ensemble Learning"],"type":"conference","department":[{"_id":"574"}],"file":[{"content_type":"application/pdf","file_id":"62008","date_updated":"2025-10-28T10:02:13Z","relation":"main_file","file_size":837462,"access_level":"open_access","file_name":"public.pdf","date_created":"2025-10-28T10:02:13Z","creator":"rupezzz"}],"date_created":"2025-10-28T10:02:40Z"},{"abstract":[{"text":"Large Language Models (LLMs) are increasingly being explored for their potential in software engineering, particularly in static analysis tasks. In this study, we investigate the potential of current LLMs to enhance call-graph analysis and type inference for Python and JavaScript programs. We empirically evaluated 24 LLMs, including OpenAI's GPT series and open-source models like LLaMA and Mistral, using existing and newly developed benchmarks. Specifically, we enhanced TypeEvalPy, a micro-benchmarking framework for type inference in Python, with auto-generation capabilities, expanding its scope from 860 to 77,268 type annotations for Python. Additionally, we introduced SWARM-CG and SWARM-JS, comprehensive benchmarking suites for evaluating call-graph construction tools across multiple programming languages.\r\n Our findings reveal a contrasting performance of LLMs in static analysis tasks. For call-graph generation, traditional static analysis tools such as PyCG for Python and Jelly for JavaScript consistently outperform LLMs. While advanced models like mistral-large-it-2407-123b and gpt-4o show promise, they still struggle with completeness and soundness in call-graph analysis across both languages. In contrast, LLMs demonstrate a clear advantage in type inference for Python, surpassing traditional tools like HeaderGen and hybrid approaches such as HiTyper. These results suggest that, while LLMs hold promise in type inference, their limitations in call-graph analysis highlight the need for further research. Our study provides a foundation for integrating LLMs into static analysis workflows, offering insights into their strengths and current limitations.","lang":"eng"}],"issue":"6","publication":"Empirical Software Engineering","citation":{"mla":"Shivarpatna Venkatesh, Ashwin Prasad, et al. “An Empirical Study of Large Language Models for Type and Call Graph Analysis in Python and JavaScript.” <i>Empirical Software Engineering</i>, vol. 30, no. 6, Springer, 2025, doi:<a href=\"https://doi.org/10.48550/ARXIV.2410.00603\">10.48550/ARXIV.2410.00603</a>.","bibtex":"@article{Shivarpatna Venkatesh_Sunil_Sabu_Mir_Reis_Bodden_2025, title={An Empirical Study of Large Language Models for Type and Call Graph Analysis in Python and JavaScript}, volume={30}, DOI={<a href=\"https://doi.org/10.48550/ARXIV.2410.00603\">10.48550/ARXIV.2410.00603</a>}, number={6}, journal={Empirical Software Engineering}, publisher={Springer}, author={Shivarpatna Venkatesh, Ashwin Prasad and Sunil, Rose and Sabu, Samkutty and Mir, Amir M. and Reis, Sofia and Bodden, Eric}, year={2025} }","ama":"Shivarpatna Venkatesh AP, Sunil R, Sabu S, Mir AM, Reis S, Bodden E.

This classification is based on the factorizability of homogeneous multivariate polynomials and is invariant under unitary transformations. The classes physically correspond to field excitations in terms of single and multiple photons, each of which is in an arbitrary irreducible superposition of quantized modes. We further show how the transitions between classes are rendered possible by photon addition, photon subtraction, and photon-projection nonlinearities. We explicitly put forward a design for a multilayer interferometer in which the states for different classes can be generated with state-of-the-art experimental techniques. Limitations of the proposed designs are analyzed using the introduced classification, providing a benchmark for the robustness of certain states and classes.</jats:p>"}],"date_created":"2025-12-09T09:08:39Z","type":"journal_article","department":[{"_id":"15"},{"_id":"569"},{"_id":"170"},{"_id":"293"},{"_id":"706"},{"_id":"636"},{"_id":"35"},{"_id":"230"},{"_id":"429"},{"_id":"623"}],"status":"public","publisher":"American Physical Society (APS)","_id":"62980","user_id":"16199","volume":7,"citation":{"chicago":"Kopylov, Denis A., Christian Offen, Laura Ares, Boris Edgar Wembe Moafo, Sina Ober-Blöbaum, Torsten Meier, Polina R.
