We show that Gaussian RBMs can generate good images just like other generative models, despite the single-layer architecture. Key innovations:
1) Gibbs-Langevin sampling;
2) modified Contrastive Divergence.

Looks super cool! It is exciting to see such a hybrid world model approach works at scale. Big congrats!

Today we are releasing JST-2, the world's first full-stack physics-native world foundation model.

Many world models learn in pixel/video space. We went back to first principles and built the entire model stack in 3D.

Generate a 3D scene in seconds and expand it in real time. Create characters with motion built in, all through one general architecture.

If you’ll be at CVPR, come check out our work LatentHOI on hand–object manipulation!
📍 Poster Session 4, #155

Want to generate realistic hand–object manipulations for unseen objects?

Check out our new paper: "LatentHOI: On the Generalizable Hand Object Motion Generation with Latent Hand Diffusion".

Appearing at #CVPR2025 in Nashville!

🚀Our new work (RetroSynFlow) on retrosynthesis:
1) SOTA discrete flow matching that leverages synthons: products->synthons->reactants
2) effective test-time reward steering

Led by my amazing students @RobinY798, @qi_yan98, with stellar collaborators Guy Wolf & @bose_joey

Robin Yadav @RobinY798 Jun 9, 2025

Excited to announce RetroSynFlow, a discrete flow matching framework for diverse and accurate retrosynthesis!

📄Paper available here: arxiv.org/abs/2506.04439

Joint work w/ @qi_yan98 , Guy Wolf, @bose_joey and @lrjconan .

👇 A quick overview 🧵

Ever wondered how card shuffling can help solve combinatorial problems like sorting, jigsaw puzzles, or TSPs?

Our ICLR 2025 (Oral) paper SymmetricDiffusers introduces a novel discrete diffusion model on finite symmetric groups to solve them in a unified and principled way!
