On-policy learning algorithm
Web28 de nov. de 2024 · The on-policy-based SARSA algorithm is an improvement from the off-policy-based Q-learning algorithm. The original SARSA algorithm is a slow learning algorithm due to its over-exploration. If the environment has less number of states, then it takes more time to converge. Web18 de jan. de 2024 · On-policy methods bring many benefits, such as ability to evaluate each resulting policy. However, they usually discard all the information about the policies which existed before. In this work, we propose adaptation of the replay buffer concept, borrowed from the off-policy learning setting, to create the method, combining …

Webpoor sample e ciency is the use of on-policy reinforcement learning algorithms, such as trust region policy optimization (TRPO) [46], proximal policy optimiza-tion(PPO) [47] or REINFORCE [56]. On-policy learning algorithms require new samples generated by the current policy for each gradient step. On the contrary, o -policy algorithms aim to ... Web12 de dez. de 2024 · Q-learning algorithm is a very efficient way for an agent to learn how the environment works. Otherwise, in the case where the state space, the action space or both of them are continuous, it would be impossible to store all the Q-values because it would need a huge amount of memory.
