Abstract

In this chapter, we will take the idea of the policy-gradient-based REINFORCE with baseline algorithm further and combine that idea with the value-estimation ideas from the DQN, thus, bringing the best of both worlds together in the form of the Actor-Critic algorithm. We will further discuss the “advantage” baseline implementation of the model with deep learning-based approximators, and take the concept further to implement a parallel implementation of the deep learning-based advantage actor-critic algorithm in the synchronous (A2C) and the asynchronous (A3C) modes.
