🔦 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/...

🔍 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

Overview of descriptions for model components (neurons, attention heads) and model abstractions (SAE features, circuits).

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)
