Policy iteration and value iteration are both dynamic programming algorithms that find an optimal policy in a reinforcement learning environment.They both employ variations of Bellman updates and exploit one-step look-ahead: In policy iteration, we start with a fixed policy. Conversely, in value iteration, … See more We can formulate a reinforcement learningproblem via a Markov Decision Process (MDP). The essential elements of such a problem are the environment, state, reward, policy, … See more In policy iteration, we start by choosing an arbitrary policy . Then, we iteratively evaluate and improve the policy until convergence: We … See more We use MDPs to model a reinforcement learning environment. Hence, computing the optimal policy of an MDP leads to maximizing rewards over time. We can utilize dynamic programming algorithms to finding an optimal … See more In value iteration, we compute the optimal state value function by iteratively updating the estimate : We start with a random value function . At each step, we update it: Hence, we look-ahead one step and go over all possible … See more
