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. WebMay 12, 2024 · Q-Learning是强化学习方法的一种。. 要使用这种方法必须了解Q-table(Q表)。. Q表是 状态-动作 与 估计的未来奖励 之间的映射表,如下图所示。.
