I got recommended Terence Tao's YouTube channel created in 2010, where he uploaded his first video just yesterday! He showcases his process of formalizing a proof in Lean 4 with the help of GitHub Copilot and the "canonical" tactic in Lean.

Gpt-2 is just 174 lines of code... How crazy is that

I am pleased to announce a new version of my RL tutorial. Major update to the LLM chapter (eg DPO, GRPO, thinking), minor updates to the MARL and MBRL chapters and various sections (eg offline RL, DPG, etc). Enjoy! arxiv.org/abs/2412.05265

As we go through a lot of excitement about RL recently with lots of cool work/results, here is a reminder that RL with a reverse KL-regularizer to the base model cannot learn new skills that were not already present in the base model. It can only amplify the existing weak skills.

PPO vs. DPO? 🤔 Our new paper proves that it depends on whether your models can represent the optimal policy and/or reward. Paper: arxiv.org/abs/2505.19770 Led by Ruizhe Shi Minhak Song

Bored of linear recurrent memories (e.g., linear attention) and want a scalable, nonlinear alternative? Our new paper “Test-Time Training Done Right” propose LaCT (Large Chunk Test-Time Training) — a highly efficient, massively scalable nonlinear memory with: 💡 Pure PyTorch

another good one!

I believe that policy gradient methods with only terminal rewards will have to break down at some level of task ood-ness/complexity, and PRMs will be necessary. This looks like a really cool addition to the theory of PRMs and CoT
