Basic solving methods of reinforcement learning (2)
brief introduction Time difference method is mainly based on the difference data of time series. It can be divided into fixed strategy and non fixed strategy. The fixed strategy time difference method is represented by sarsa algorithm; The non fixed strategy is represented by Q-learning algorithm. Sarsa algorithm The purpose of sarsa (state action reward […]
