WebMay 3, 2024 · Double Q-learning is a popular reinforcement learning algorithm in Markov decision process (MDP) problems. Clipped Double Q-learning, as an effective variant of Double Q-learning, employs the clipped double estimator to approximate the maximum expected action value. Due to the underestimation bias of the clipped double estimator, … WebHowever, the isolated effect of the clipped Q-learning in offline RL was not fully analyzed in the previous works, as they use the technique only as an auxiliary term that adds up to …
WebWe show that Q-learning’s performance can be poor in stochastic MDPs because of large overestimations of the action val-ues. We discuss why this occurs and propose an algorithm called Double Q-learning to avoid this overestimation. The update of Q-learning is Qt+1(st,at) = Qt(st,at)+αt(st,at) rt +γmax a Qt(st+1,a)−Qt(st,at) . (1) Webcd AC_CDQ_code python3 main.py. For AC-CDDQN, we evaluate it on the MinAtar benchmark.
