Researchers have developed DIPOLE (Dichotomous Diffusion Policy Optimization), a novel reinforcement learning algorithm designed for stable and controllable diffusion policy optimization. This method decomposes the optimal policy into two dichotomous policies, one for reward maximization and one for minimization, allowing for flexible control during action generation. DIPOLE has demonstrated effectiveness in offline and offline-to-online RL settings on benchmarks like ExORL and OGBench, and has been applied to train a large vision-language-action model for autonomous driving on the NAVSIM benchmark.
