WebDec 27, 2024 · Hi all, I’ve been playing around with the REINFORCE algorithm, and decided to modify the example found here to include a replay memory buffer. For some reason, the changes mean that the network no longer learns very well, even when the memory buffer is being used in the same way as the original lists holding the actions and log probs (as is … WebThis file contains bidirectional Unicode text that may be interpreted or compiled differently than what appears below.
