In this article, we will focus our attention on another algorithm - Soft Actor-Critic (SAC). It was first presented in the article "Soft Actor-Critic: Off-Policy Maximum Entropy Deep Reinforcement Learning with a Stochastic Actor" (January 2018). The method was presented almost simultaneously with TD3. It has some similarities, but there are also differences in the algorithms. The main goal of SAC is to maximize the expected reward given the maximum entropy of the policy, which allows finding ...
