Deep Reinforcement Learning with Double Q-learning
Deep Reinforcement Learning with Double Q-learningHado van HasseltandArthur GuezandDavid SilverGoogle DeepMindAbstractThe popular Q- Learning algorithm is known to overestimateaction values under certain conditions. It was not previouslyknown whether, in practice, such overestimations are com-mon, whether they harm performance, and whether they cangenerally be prevented. In this paper, we answer all thesequestions affirmatively. In particular, we first show that therecent DQN algorithm, which combines Q- Learning with adeep neural network, suffers from substantial overestimationsin some games in the Atari 2600 domain .
in some games in the Atari 2600 domain. We then show that the idea behind the Double Q-learning algorithm, which was introduced in a tabular setting, can be generalized to work with large-scale function approximation. We propose a spe-cific adaptation to the DQN algorithm and show that the re-sulting algorithm not only reduces the observed ...
