WebApr 10, 2024 · Essentially, deep Q-Learning replaces the regular Q-table with the neural network. Rather than mapping a (state, action) pair to a Q-value, the neural network maps input states to (action, Q-value) pairs. In 2013, DeepMind introduced Deep Q-Network (DQN) algorithm. DQN is designed to learn to play Atari games from raw pixels. WebApr 11, 2024 · Implementing the Double DQN algorithm. The key idea behind Double Q-learning is to reduce overestimations of Q-values by separating the selection of actions from the evaluation of those actions so that a different Q-network can be used in each step. When applying Double Q-learning to extend the DQN algorithm one can use the online Q …
