🧵 Everyone is chasing new diffusion models—but what about the representations they model from? We introduce Discrete Latent Codes (DLCs): - Discrete representation for diffusion models - Uncond. gen. SOTA FID (1.59 on ImageNet) - Compositional generation - Integrates with LLM 🧱

This is a very elegant way to look at test-time scaling. Among other things, we used this perspective to derive a simple and efficient method for self-verification and to provide an understanding of the limits of test-time scaling.

1/n Does scaling test-time compute on LLM self-verification keep paying off? 🤔 Not really. Our work shows scaling compute makes judgements more consistent, but not necessarily more correct 🧵 Paper: arxiv.org/abs/2611.00350 Blog: anirudhb11.github.io/blog/scorpio Code:

I'll be at #neurips next week to present this work with @mnoukhov and @AaronCourville !

It was awesome collaborating on that project. We show why SEM improves RL training of RL agents 🚀.

🔊Simplicial Embeddings (SEMs) Improve Sample Efficiency in Actor-Critic Agents🔊 In our recent preprint we demonstrate that the use of well-structured representations (SEMs) can dramatically improve sample efficiency in RL agents. 1/X
