arXiv:2603.10250v2 Announce Type: replace Abstract: A commonly used family of RL algorithms for diffusion policies conducts softmax reweighting over samples from the behavior policy, which often induces an overgreedy policy and fails to utilize feedback from negative samples. In this work, we introduce GeMPO, a simple and unified framework that generalizes reweighting scheme in diffusion RL from softmax to general monotonic functions. GeMPO revisits diffusion RL via a measure matching perspective: First, we construct a virtual target policy measure via solving a regularized policy optimization
This work is a refinement and advancement in a specific area of AI, building on existing diffusion reinforcement learning techniques which are gaining traction.
Improved reinforcement learning algorithms lead to more efficient and capable AI systems, impacting a wide range of applications from robotics to autonomous agents.
The introduction of GeMPO offers a more generalized and potentially robust method for policy optimization in diffusion RL, moving beyond limitations of prior softmax reweighting schemes.
