🔦 Past Paper Highlight: PRISM generates multi-concept descriptions of LLM features by clustering high-activation inputs and labeling each cluster. Two evaluation metrics measure the semantic diversity and faithfulness of the resulting descriptions. 🔗 proceedings.neurips.cc/paper_files/...

Last week, Dr. Nils Feldhus @nfel.bsky.social, postdoctoral researcher at @tuberlin.bsky.social and @bifold.berlin, visited our lab and presented his research during our weekly lab meeting.

🔍 Are you curious about uncovering the underlying mechanisms and identifying the roles of model components (neurons, …) and abstractions (SAEs, …)? We provide the first survey of concept description generation and evaluation methods. Joint effort w/ @lkopf.bsky.social 📄 arxiv.org/abs/2510.01048

Happy to share that our PRISM paper has been accepted at #NeurIPS2025 🎉 In this work, we introduce a multi-concept feature description framework that can identify and score polysemantic features. 📄 Paper: arxiv.org/abs/2506.15538 #NeurIPS #MechInterp #XAI

🔍 When do neurons encode multiple concepts? We introduce PRISM, a framework for extracting multi-concept feature descriptions to better understand polysemanticity. 📄 Capturing Polysemanticity with PRISM: A Multi-Concept Feature Description Framework arxiv.org/abs/2506.15538 🧵 (1/7)

Still overwhelmed by the amazing response to our poster session at @neuripsconf.bsky.social with Anna Hedström and Marina Höhne! It was incredible to have such lively and inspiring discussions with brilliant people whose work I admire. ✨

I’ll be presenting our work at @neuripsconf.bsky.social in Vancouver! 🎉 Join me this Thursday, December 12th, in East Exhibit Hall A-C, Poster #3107, from 11 a.m. PST to 2 p.m. PST. I'll be discussing our paper “CoSy: Evaluating Textual Explanations of Neurons.”
