WebAug 29, 2024 · First, TD3, as it is also abbreviated, learns two Q-functions and uses the smaller value to construct the targets. Further, the policy (responsible for selecting initial actions) is updated less frequently, and noise is added to smooth the Q-function. Entropy-regularized Reinforcement Learning. WebSoft Actor Critic (SAC) is an algorithm that optimizes a stochastic policy in an off-policy way, forming a bridge between stochastic policy optimization and DDPG-style approaches.

WebHER is an algorithm that works with off-policy methods (DQN, SAC, TD3 and DDPG for example). HER uses the fact that even if a desired goal was not achieved, other goal may have been achieved during a rollout. It creates “virtual” transitions by relabeling transitions (changing the desired goal) from past episodes.
