WebMar 24, 2024 · The more episodes are collected, the better because the estimates of the functions will be. However, there’s a problem. If the algorithm for policy improvement always updates the policy greedily, meaning it takes only actions leading to immediate reward, actions and states not on the greedy path will not be sampled sufficiently, and potentially … WebFor this, we introduce the concept of the expected return of the rewards at a given time step. For now, we can think of the return simply as the sum of future rewards. Mathematically, we define the return G at time t as G t = R t + 1 + R t + 2 + R t + 3 + ⋯ + R T, where T is the final time step. It is the agent's goal to maximize the expected ...
