In the case of value-based methods, Sarsa is also on-policy but generally used in combination with epsilon-greedy. In the case of DPG, the impression I got from a very quick glance through the paper is that they really want to learn something …

WebMar 6, 2024 · Behaving greedily with respect to any other value function is a greedy … WebGreedy Policy Search (GPS) is a simple algorithm that learns a policy for test-time data augmentation based on the predictive performance on a validation set. GPS starts with an empty policy and builds it in an iterative fashion. Each step selects a sub-policy that provides the largest improvement in calibrated log-likelihood of ensemble predictions and … birch lumber home depot
