Bias in Natural Actor-Critic Algorithms E[ t=0 γ t rt |s0 =s, θ]. Similarly, the state-action value ∞ function is Qθ (s, a) = E[ t=0 γ t rt |s0 =s, a0 =a, θ]. The discounted state distribution, dθ , gives the probability of each state when using policy ...

Simultaneously, in order to improve the sampling efficiency of the algorithm, we propose an improved prioritized experience replay mechanism by modifying the priority definition instead of the original random sampling. Experiments show that, compared with two state-of-the-art algorithms, our algorithm ...

AC is biased 注意baseline要求是只与state相关,才可证是unbiased。而AC里,E[γV(st+1)−V(st)...
