Excited to be at #ICML2026 this week presenting joint work with Chongyi Zheng and @ben-eysenbach.bsky.social on "Consistent Zero-Shot Imitation with Contrastive Goal Inference" (1/4)

🧠🔭Today's AI models synthesize knowledge acquired from the internet/books/etc. Ultimately, that knowledge usually derives from real experiments. We know (say) the moon's mass because a human did a science experiment. How well do AI models fare at generating knowledge? 🤔

Kids spend years playing with blocks, building spatial+arithmetic skills. Today, AI models just read. While AI research often conflates reasoning with language models, block-building lets us study how embodied reasoning might emerge from exploration and trial-and-error learning!

Check out @raj-ghugare.bsky.social's new paper on the surprising effectiveness of normalizing flows (NF) in RL 🚀 This project changed my mind in 2 ways: 1/ Diffusion policies, flow-models, and EBMs have become ubiquitous in RL. Turns out NFs can perform as well -- no ODEs/SDEs required!

tldr: increase the depth of your RL networks by several orders of magnitude. Our new paper shows that very very deep networks are surprisingly useful for RL, if you use resnets, layer norm, and self-supervised RL! Paper, code, videos: wang-kevin3290.github.io/scaling-crl/

Excited to share new work led by @vivekmyers.bsky.social and @crji.bsky.social that proves you can learn to reach distant goals by solely training on nearby goals. The key idea is a new form of invariance. This invariance implies generalization w.r.t. the horizon.
