arXiv:2603.27450v2 Announce Type: replace Abstract: Thanks to their remarkable flexibility, diffusion models and flow models have emerged as promising candidates for policy representation. However, efficient reinforcement learning (RL) upon these policies remains a challenge due to the lack of explicit log-probabilities for vanilla policy gradient estimators. While numerous attempts have been proposed to address this, the field lacks a unified perspective to reconcile these seemingly disparate methods, thus hampering ongoing development. In this paper, we bridge this gap by introducing a compr
This publication represents a critical advancement in unifying disparate methodologies for integrating diffusion and flow models into reinforcement learning, which are increasingly seen as powerful policy representations.
A more efficient and unified framework for Reinforcement Learning with advanced diffusion policies could significantly accelerate the development of more capable and autonomous AI agents, impacting various sectors.
The explicit absence of log-probabilities for vanilla policy gradient estimators, a previous hurdle for diffusion/flow policies, is being systematically addressed, potentially leading to more robust and scalable RL techniques.
