The inspiring life journey of David Fajgenbaum, MD is set to become a feature film. The movie aims to capture his determination and crowdsourced research that led to finding his own cure for Castleman Disease using an already FDA-approved drug. spr.ly/60102o5Du

I just wrote a position paper on the relation between statistics and large language models: Do Large Language Models (Really) Need Statistical Foundations? arxiv.org/abs/2505.19145 Any comments are welcome. Thx

🚨New paper🚨 Excited to share our latest on nature today: The PIVOT PENALTY in research. nature.com/articles/s4158… More than five years in the making. Key finding: The impact of new research steeply declines the further a researcher moves from their previous work.

We posted a paper on optimization for deep learning: arxiv.org/abs/2505.21799 Recently there's a surge of interest in *structure-aware* optimizers: Muon, Shampoo, Soap. In this paper, we propose a unifying preconditioning perspective, offer insights into these matrix-gradient

Great minds think alike! Alan Turing cracked Enigma in WWII; Brad Efron asked how many words Shakespeare knew. They used the same method. We use this method for LLM evaluation—to evaluate certain unseen capabilities of LLMs: arxiv.org/abs/2506.02058

👉 Check out our new paper, "Evaluating the Unseen Capabilities: How Many Theorems Do LLMs Know?", which explores how much knowledge LLMs don’t show us. Grateful to Weijie Su and Qi Long for their mentorship, and to Xiang Li for spearheading this project. Details below 👇
