Vor etwa einem halben Jahr endete mein erster Versuch, mit Unterstützung von ChatGPT einen Zivilprozess selbst zu führen. Das Ergebnis vorweg: Wir haben verloren, auf eine ziemlich unbefriedigende Art. Das Amtsgericht hat nicht entschieden, ob meine tatsächliche Position gegenüber der Read more…
Rosalind Picard‘s keynote at NeurIPS 2024 sparked quite a controversy, leading to an apology from NeurIPS and Picard herself. I was wondering what ChatGPT thought of her slides. Here is the result: You said: What do you See? ChatGPT said: Read more…
Abstract As recommender systems become increasingly prevalent, the environmental impact and energy efficiency of training these large-scale models have come under scrutiny. This paper investigates the potential for energy-efficient algorithm performance by optimizing dataset sizes through downsampling techniques. We conducted Read more…

Accepted for publication as late-breaking-result (LBR) at the 18th ACM Conference on Recommender Systems. Read the article as PDF here. Abstract When designing recommender-systems experiments, a key question that has been largely overlooked is the choice of datasets. In a Read more…
Full pre-print as PDF: https://arxiv.org/abs/2408.08203 Abstract As global warming soars, the need to assess the environmental impact of research is becoming increasingly urgent. Despite this, few recommender systems research papers address their environmental impact. In this study, we estimate the Read more…
The German Research Association (Deutsche Forschungsgemeinschaft, DFG) recently issued guidelines for using artificial intelligence, including tools like ChatGPT, to write research papers and grant applications. The DFG supports using AI for these purposes, excluding reviews but emphasizes the need for Read more…
I recently enjoyed spending one week in Taipei, Taiwan, attending the PAKDD 2024 conference and meeting a few colleagues. Despite a full schedule, I had enough time to explore the city and get to know the Taiwanese food and a Read more…
