How fast can we unlearn data from recommendation models for the #righttobeforgotten? We unlearn interactions from kNN models on 1m users & 250m interactions with sub-second latency in our upcoming short paper SIGIR 2024 dl.acm.org/doi/10.1145/35… Joint work w/ Mozhdeh Ariannezhad Maarten de Rijke

Awesome paper by xiaozhong lyu Stefan Grafberger @ce__zhang Sebastian shows how #RAG can be improved through data importance learning. The approach learns weights for data sources based on their performance on a validation set and then re-weights or prunes the corpus. 1/3

Checkout our vision on "Red Onions, Soft Cheese and Data: From Food Safety to Data Traceability for Responsible AI" sites.computer.org/debull/A24mar/… We ask what reponsible data management can learn from the existing regulations and processes for food safety (w/ Stefan Grafberger & Ce Zhang)

LLMs show a huge potential for data wrangling. But how we can we increase their parameter-, compute- and sample efficiency for real-world use cases? Zhang Zeyu will present our ideas for this at the DBML workshop at #icde2024 IEEE ICDE Conference today! wis.ewi.tudelft.nl/assets/files/d…
