Parameterized deep Q-network based energy management

WebThe deep Q-network (DQN) algorithm is a model-free, online, off-policy reinforcement learning method. A DQN agent is a value-based reinforcement learning agent that trains a critic to estimate the return or future rewards. DQN is a variant of Q-learning, and it operates only within discrete action spaces. For more information, Deep Q-Network ... WebTo model the dependence, Parameterized DQN (PDQN) (Xiong et al., 2024) pro-poses a hybrid structure of DQN (Mnih et al., 2015) and DDPG. The discrete pol-icy is represented by a DQN which ad-ditionally takes as input all the continu-ous parameters output by the DDPG ac-tor; while the DQN also serves as the critic of DDPG. Some variants of such ... cynthia cox dds oakland
