Web1 de jul. de 2024 · Controlling overestimation bias. State-of-the-art algorithms in continuous RL, such as Soft Actor Critic (SAC) [2] and Twin Delayed Deep Deterministic Policy Gradient (TD3) [3], handle these overestimations by training two Q-function approximations and using the minimum over them. This approach is called Clipped Double Q-learning [2]. Webkeeping the estimation bias close to zero, when compared to the state-of-the-art ensemble methods such as REDQ [6] and Average-DQN [2].
