We start by proving the so-called policy gradient theorem which is then shown to give rise to an efficient way of constructing noisy, but unbiased gradient estimates in the presence of a simulator. WebWe consider reinforcement learning control problems under the average reward criterion in which non-zero rewards are both sparse and rare, that is, they occur in very few states and have a very small steady-state probability. Using Renewal Theory and Fleming-Viot particle systems, we propose a novel approach that exploits prior knowledge on the sparse … phone verified battlenet accounts for sale
