Introducing MIMIC: a new foundation model trained natively across DNA, RNA and proteins. MIMIC is multimodal and generative: it can use structure, regulation, evolution, and experimental context to infer missing biology or design new sequences. 🧵⬇️

New NeurIPS paper! Why do LMs represent concepts linearly? We focus on LMs's tendency to linearly separate true and false assertions, and provide an analysis of the truth circuit in a toy model. A joint work with Gilad Yehudai, @tallinzen.bsky.social, Joan Bruna and @albertobietti.bsky.social.

✨ Thank you #AISTATS for the best paper award!! 📜 arxiv.org/abs/2410.11067 💡What does VI learn and under what conditions? The answer lies in symmetry. 🤝 Honored to share this award with my co-author Lawrence Saul from @flatironinstitute.org

Come hear Matt Smart's talk about in-context denoising with transformers at the Associative memory workshop #ICLR25, 2:15pm! This task refines the connection between transformers and associative memories. w/ M Smart and @albertobietti.bsky.social at @flatironinstitute.org

Given a high-quality verifier, language model accuracy can be improved by scaling inference-time compute (e.g., w/ repeated sampling). When can we expect similar gains without an external verifier? New paper: Self-Improvement in Language Models: The Sharpening Mechanism arxiv.org/abs/2412.01951
