Excited to share Flow Matching Policy Gradients: expressive RL policies trained from rewards using flow matching. It’s an easy, drop-in replacement for Gaussian PPO on control tasks.

- Decentralized Diffusion Models power stronger models trained on more accessible infrastructure. DDMs mitigate the networking bottleneck that locks training into expensive and power-hungry centralized clusters. They scale gracefully to billions of parameters and generate
00:00 - Replying to @davidrmcallCheck out our blog post at flowreinforce.github.io We developed interactive plots that explain the connection between flow/diffusion models and RL. w/ a great team of collaborators! @Songwei_Ge @brenthyi @ChungMinKim @ethanjohnweber @redstone_hong @HavenFeng @akanazawa

- I’ll be at #NeurIPS2024 this week presenting Rethinking Score Distillation as a Bridge Between Image Distributions! Poster Presentation: Friday 4:30-7:30 PM Come chat with me or @holynski_ about lifting diffusion models to 3D!
00:00 - Humanoids on campus! Check out our new work on context-aware locomotionour new system trains humanoid robots using data from cell phone videos, enabling skills such as climbing stairs and sitting on chairs in a single policy (w/ @redstone_hong @junyi42 @davidrmcall)

- RDM is now published at Nature Methods! This was a 3 year effort and my introduction to academic research. I’m fortunate to have been mentored by one of the smartest people I’ve ever met @the_legitamit!Ring deconvolution microscopy is now published at @naturemethods! nature.com/articles/s4159… There are some fun new additions including light-sheet deconvolution 🫡 Stay tuned for the official python package release next week! Any feature suggestions are more than welcome 😃

- Replying to @davidrmcallStandard diffusion models communicate gradients at every optimization step, a network load that only centralized clusters can support. Decentralized diffusion models divide training into independent pieces that can proceed on different hardware in different locations. This is a
00:00 - Anything is possible with Viser!July has been a big month for Viser! - Released v1.0.0😊 - We did some writing Some demos👇
00:00 - Replying to @davidrmcallThis was only possible thanks to mentors Matthew Tancik and Jiaming Song (@baaadas), as well as the support of the rest of the fantastic @LumaLabsAI research team! Thank you for hosting me as an intern.
- Replying to @davidrmcallThis produces an ensemble whose predictions combine at test-time. You can drop experts at test-time to save on computation. In fact, we only inference a single expert per step in our comparisons and we outperform standard diffusion models for with the same FLOP budgets at train
