I am pleased to announce that Lukas Wegmeth has completed his PhD in computer science after 3.5 years, earning a magna cum laude. The early completion is a success for him and, frankly, a loss for our group. Lukas worked Read more…
Following my recent visit to Prof. Min-Yen Kan at the National University of Singapore, Moritz Baumgart, Min-Yen Kan and I co-authored a paper critically evaluating Sakana’s AI Scientist (to be published in SIGIR Forum). Our review attracted the attention of Read more…
Over the past semester, several Bachelor students at the University of Siegen undertook a bold challenge in our Machine Learning Praktikum: they didn’t just learn algorithms—they tried to reproduce published machine learning or recommender systems research. Each student or team Read more…
We are excited to share that our PhD student, Tobias Vente, presented our research paper, “The Potential of AutoML for Recommender Systems,” at the ACM UMAP 2025 conference held at the Verizon Executive Education Center at Cornell Tech on Roosevelt Island, New York City. Tobias presented our Read more…
In diesem Blogpost dokumentiere ich, wie das Landesamt für Besoldung und Versorgung NRW (LBV) versucht hat, mir eine Versorgungsauskunft faktisch zu verwehren, wie anschließend zu meinen Ungunsten entschieden wurde – und wie ich am Ende dennoch rund acht Jahre mehr Read more…
Until recently, AI systems were primarily used for narrow tasks such as analysing large datasets or identifying patterns in complex information. However, with large-language models (LLMs), we are approaching a new frontier: the full automation of the scientific process, from Read more…
We are thrilled to announce that Dr. André Klahold has been appointed an Honorary Professor at the University of Siegen’s Department of Electrical Engineering and Computer Science. This prestigious recognition underscores his significant contributions to artificial intelligence, content management, and Read more…
Earlier this year, we published a post about our paper and tool Checky, the Paper-Submission Checklist-Generator for Authors, Reviewers and LLMs, after its acceptance at ECIR 2025. Now, I’m excited to share my experience presenting the work as a demonstration paper at the Read more…
Lukas Wegmeth & Tobias Vente, both fourth-year Ph.D. students at the Intelligent Systems Group, were invited to SFI MediaFutures in Bergen, Norway, to give a talk on the sustainability of Recommender Systems on April 4th, 2025. Prof. Sole Pera also Read more…
PhD students Lukas Wegmeth and Tobias Vente had the opportunity to visit Tsinghua University in Beijing, China, for a month-long research visit with Professor Min Zhang, a leading expert in recommender systems and information retrieval. Professor Min Zhang is a Read more…
