New framework tackles offline maximum entropy reinforcement learning

Researchers have developed a new framework for offline maximum entropy reinforcement learning that separates environment modeling from value function learning. This approach utilizes conditional diffusion models based on probability flow ODEs to estimate reward distributions and transition kernels. The resulting distributional estimators approximate the soft optimal Bellman operator, which is then minimized using deep neural networks to learn the optimal soft action-value function. The method includes non-asymptotic theoretical guarantees for both the estimation of distributional operators and the learning of soft values, with results that do not require Bellman completeness.
