WEBNov 17, 2018 · Actor-Critics aim to take advantage of all the good stuff from both value-based and policy-based while eliminating all their drawbacks. And how do they do this? The principal idea is to split the model in two: one for computing an action based on a state and another one to produce the Q values of the action.

WEBFeb 7, 2023 · Actor-critic methods are a popular approach to reinforcement learning, which involves the use of two separate components: the actor and the critic. The goal of the actor is to learn a policy that maximizes the expected reward, while the goal of the critic is to learn an accurate value function that can be used to evaluate the actor’s actions.
