Model-based Reinforcement Learning for Continuous Control with Posterior Sampling
In this paper, we study model-based posterior sampling for reinforcement learning (PSRL) in continuous state-action spaces theoretically and empirically.
Efficient Exploration for Model-based Reinforcement Learning with Continuous States and Actions
Our bound can be extended to nonlinear cases as well: using linear kernels on the feature representation $\phi$, the Bayesian regret bound becomes $\tilde{O}(H^{3/2}d_{\phi}\sqrt{T})$, where $d_\phi$ is the dimension of the representation space.
