Neural estimation of dynamical systems = data-driven parameter estimation + strong maths modelling This is a fascinating topic, isn't it? I'm glad to contribute to this topic with great talents Michael Poli Luca Scimeca SanghyukChun arxiv.org/abs/2106.04165 (NeurIPS 2021) 1/

Can we perform unbiased bayesian posterior inference with a diffusion model prior? We propose Relative Trajectory Balance (RTB) which allows us to directly optimize for this posterior model. We apply this to several tasks in image, language and control!🧵arxiv.org/abs/2405.20971

Resharing this thread now that our paper has been accepted to #NeurIPS! We propose a new (off-policy) objective "Relative Trajectory Balance" to train a diffusion prior with a reward function to obtain the Bayesian posterior. We can do KL regularized RLHF similar to LLMs now!

Is there a universal strategy to turn any generative model—GANs, VAEs, diffusion models, or flows—into a conditional sampler, or finetuned to optimize a reward function? Yes! Outsourced Diffusion Sampling (ODS) accepted to ICML Conference , does exactly that!
