"WebThis section on value-based methods is split into two parts. I will first lay out three classic algorithms: policy iteration, value iteration, fitted-Q iteration; and then shift to state-of-the-art deep Q learning. I think it's a main goal to not only understand each algorithm but also how these value-based methods relate to each other. " - Fitted value iteration
