WebFeb 17, 2024 · Theoretically, nothing precludes the use of $\lambda$-returns in actor-critic methods.The $\lambda$-return is an unbiased estimator of the Monte Carlo (MC) return, which means they are essentially interchangeable.In fact, as discussed in High-Dimensional Continuous Control Using Generalized Advantage Estimation, using the $\lambda$ … WebAn Eligibility Trace is a memory vector z t ∈ R d that parallels the long-term weight vector w t ∈ R d. The idea is that when a component of w t participates in producing an …

WebThe eligibility trace is one of the basic mechanisms used in reinforcement learning to handle delayed reward. In this paper we introduce a new kind of eligibility trace, the replacing trace, analyze it theoretically, and show that it results in faster, more reliable learning than the conventional trace. WebKeep the eligibility trace as a lookup table that is reset between episodes (enforce episodes even if they are artificial to the problem by terminating at some given time step?). Though this doesn't really solve the backprop issue unless the episodes are very small.
