GradientDICE

** Overview of GradientDICE ** GradientDICE is a computational method used in the field of off-policy reinforcement learning. Specifically, it is used to estimate the density ratio between the state distribution of the target policy and the sampling distribution. What is Density Ratio Learning? In order to understand GradientDICE, it is important to first understand density ratio learning. Density ratio learning is a technique used in machine learning that involves comparing two probabili
