Stochastic control or stochastic optimal control is a sub field of control theory that deals with the existence of uncertainty either in observations or in the noise that drives the evolution of the system. << /S /GoTo /D (subsection.2.3) >> 76 0 obj All of these methods involve formulating control or reinforcement learning endobj (Posterior Policy Iteration) endobj Reinforcement Learningfor Continuous Stochastic Control Problems 1031 Remark 1 The challenge of learning the VF is motivated by the fact that from V, we can deduce the following optimal feed-back control policy: u*(x) E arg sup [r(x, u) + Vx(x).f(x, u) + ! Our approach consists of two main steps. endobj Reinforcement Learning. Reinforcement learning (RL) has been successfully applied in a variety of challenging tasks, such as Go game and robotic control [1, 2]The increasing interest in RL is primarily stimulated by its data-driven nature, which requires little prior knowledge of the environmental dynamics, and its combination with powerful function approximators, e.g. On Stochastic Optimal Control and Reinforcement Learning by Approximate Inference (Extended Abstract)∗ Konrad Rawlik School of Informatics University of Edinburgh Marc Toussaint Inst.
