Critic-only method
WebOct 18, 2024 · In fact, our methodology is such that a rate for actor-critic can be derived for any critic only method for which a convergence rate in expectation on the parameters can be expressed. In particular, we characterize the rates for actor-critic with temporal difference (TD) and gradient TD (GTD) critic steps. Furthermore, ... WebGradient Theorem [28]. Actor-only methods can be naturally applied to continuous setting but suf-fer from high variance when estimating the policy gradient. On the other hand, critic-only methods, such as temporal difference learning [26] and Q-learning [32], focus on learning a value function
