arXiv:2606.14801v1 Announce Type: cross Abstract: Flow-matching and diffusion policies are expressive action generators, but optimizing them with temporal-difference reinforcement learning (RL) remains difficult. Effective policy extraction requires exploiting the critic's action gradient, yet directly backpropagating this signal through a multi-step denoising process can be numerically unstable. Existing methods work around this either by discarding gradient information, distilling the policy into a simpler one-step actor, or repeatedly fine-tuning the denoising policy as the critic improves.
The continuous drive for more efficient and stable reinforcement learning methods for generative AI policies, particularly in the context of recent advancements in flow-matching and diffusion models, makes this research timely.
Improving the stability and efficiency of training sophisticated generative AI models using reinforcement learning could unlock new capabilities in autonomous systems and complex decision-making, accelerating the development of advanced AI agents.
The ability to more reliably and efficiently optimize flow-matching and diffusion policies with temporal-difference RL mitigates previous numerical instability issues, potentially leading to faster development and deployment of advanced AI agents.
