Geometric Variance Reduction in Markov Chains: Application to Value Function and Gradient Estimation
15 years 1 months ago
We study a sequential variance reduction technique for Monte Carlo estimation of functionals in Markov Chains. The method is based on designing sequential control variates using s...
