Webb7 mars 2024 · The idea of Q-Learning is easy to grasp: We select our next action based on our behavior policy, but we also consider an alternative action that we might have taken, had we followed our target policy. This allows the behavior and target policies to improve, making use of the action-values Q(s, a).The process works similarly to off … WebbIn this lecture we look at off policy control for monte carlo algorithms via importance sampling.
