Webb11 nov. 2024 · Q-learning is a model-free reinforcement learning algorithm that is used to find an optimal policy in a Markov decision process problem. The algorithm learns the action-value function Q=Q(s, a), which describes the value corresponding to a given action, carried out on a given state. Q-learning can work both on-policy and off-policy, and also … State–action–reward–state–action (SARSA) is an algorithm for learning a Markov decision process policy, used in the reinforcement learning area of machine learning. It was proposed by Rummery and Niranjan in a technical note with the name "Modified Connectionist Q-Learning" (MCQ-L). The alternative name SARSA, proposed by Rich Sutton, was only mentioned as a footnote. fire fighting pipe https://rimguardexpress.com
