I've got to say, the guy who accidentally became the Director of the FBI does 100% look like the guy who accidentally becomes the Director of the FBI in a mid-2000s comedy about a guy who accidentally becomes the Director of the FBI

🚀 Policy gradient methods like DeepSeek’s GRPO are great for finetuning LLMs via RLHF. But what happens when we swap autoregressive generation for discrete diffusion, a rising architecture promising faster & more controllable LLMs? Introducing SEPO ! 📑

Claimed solution for the moving sofa problem? It looks intense, I hope it's correct

Optimality of Gerver's Sofa
We resolve the moving sofa problem by showing that Gerver's construction with 18 curve sections attains the maximum area $2.2195\cdots$.

As an AC/SAC for too many conferences right now, I highly recommend people in these roles to gently nudge reviewers who don't reply after author rebuttal. People can be forgetful, or have busy lives but will often reply / update their scores when reminded to.
