Policy Gradient Methods
A2C
Introduced by Mnih et al. in Asynchronous Methods for Deep Reinforcement LearningA2C, or Advantage Actor Critic, is a synchronous version of the A3C policy gradient method. As an alternative to the asynchronous implementation of A3C, A2C is a synchronous, deterministic implementation that waits for each actor to finish its segment of experience before updating, averaging over all of the actors. This more effectively uses GPUs due to larger batch sizes.
