Apprentissage par renforcement (3)
We propose three members in the family, the averaging TD, double TD, and periodic TD, where the target variable is updated through an averaging, symmetric, or ...
Lecture 10: Q-Learning, Function Approximation, Temporal ...Choosing greedy actions to update action values makes Q-learning an off- policy TD method, while SARSA is an on-policy TD method which uses e- greedy method. A Short Tutorial on Reinforcement Learning. - IFIP Open Digital LibraryTemporal difference (TD) methods constitute a class of methods for learning predictions in multi-step prediction problems, parameterized by a recency factor . Sequential decision making Control: SARSA & Q-learningFigure 6.12: Q-learning: An off-policy TD control algorithm. Its simplest form, one-step Q-learning, is defined by. Q(St,At) ?
