Q-learning算法详解
WebKey Terminologies in Q-learning. Before we jump into how Q-learning works, we need to learn a few useful terminologies to understand Q-learning's fundamentals. States(s): the current position of the agent in the environment. Action(a): a step taken by the agent in a particular state. Rewards: for every action, the agent receives a reward and ... WebSep 3, 2024 · To learn each value of the Q-table, we use the Q-Learning algorithm. Mathematics: the Q-Learning algorithm Q-function. The Q-function uses the Bellman equation and takes two inputs: state (s) and action (a). Using the above function, we get the values of Q for the cells in the table. When we start, all the values in the Q-table are zeros.

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.
