Researchers have developed a new theoretical framework for Posterior Sampling Reinforcement Learning (PSRL) using Gaussian Processes, specifically addressing continuous control problems in unbounded state spaces. The proposed GP-PSRL algorithm achieves a Bayesian regret bound of $\widetilde{\mathcal{O}}(H\sqrt{\gamma_TT})$, resolving limitations in prior theoretical work. This advancement provides a stronger theoretical foundation for analyzing PSRL in complex environments. AI
