Really excited about this new paper. As someone who spent a ton of time training regular flows with MLE and got burned FORT training actually works making flows cool again 🌊

The supervision signal in AI4Science is so crisp that we can solve very complicated problems almost without any data or RL! In this project, we train a model to solve the Schrödinger equation for different molecular conformations using Density Functional Theory (DFT) In the

Why do we keep sampling from the same distribution the model was trained on? We rethink this old paradigm by introducing Feynman-Kac Correctors (FKCs) – a flexible framework for controlling the distribution of samples at inference time in diffusion models! Without re-training

Check out FKCs! A principled flexible approach for diffusion sampling. I was surprised how well it scaled to high dimensions given its reliance on importance reweighting. Thanks to great collaborators Mila - Institut québécois d'IA Vector Institute Imperial College London and Google DeepMind. Thread👇🧵

Given q_t, r_t as diffusion model(s), an SDE w/drift β ∇ log q_t + α ∇ log r_t doesn’t sample the sequence of geometric avg/product/tempered marginals! To correct this, we derive an SMC scheme via PDE perspective Resampling weights are ‘free’, depend only on (exact) scores!

🚨 I heard people saying that Diffusion Samplers are actually not more efficient than MD? Well, if that's you, check out our new paper PITA done in collab with a dream team in the 🧵 below👇. Finally, a diffusion sampler that is more efficient in # energy evals compared to
