WebJun 19, 2024 · Experience replay enables reinforcement learning agents to memorize and reuse past experiences, just as humans replay memories for the situation at hand. Contemporary off-policy algorithms either replay past experiences uniformly or utilize a rule-based replay strategy, which may be sub-optimal. In this work, we consider learning a … WebThe second tricky thing is that, in the expression above, p_\theta (x) pθ(x) represents the probability of the whole chain of actions that gets us to a final cumulative reward. But our neural net just computes the probability for one action. This is where the Markov property comes into play.
