On-policy learning algorithm

WebI understand that SARSA is an On-policy algorithm, and Q-learning an off-policy one. Sutton and Barto's textbook describes Expected Sarsa thusly: In these cliff walking results Expected Sarsa was used on-policy, but in general it might use a policy different from the target policy to generate behavior, in which case it becomes an off-policy algorithm.

WebFigure 3: SARSA — an on-policy learning algorithm [1] ε-greedyfor exploration in algorithm means with ε probability, the agent will take action randomly. This method is used to increase the exploration because, without it, the agent may be stuck in a local optimal. WebBy customizing a Q-Learning algorithm that adopts an epsilon-greedy policy, we can solve this re-formulated reinforcement learning problem. Extensive computer-based simulation results demonstrate that the proposed reinforcement learning algorithm outperforms the existing methods in terms of transmission time, buffer overflow, and effective throughput.
