WebDec 3, 2015 · On-policy and off-policy learning is only related to the first task: evaluating Q ( s, a). The difference is this: In on-policy learning, the Q ( s, a) function is learned from actions that we took using our current policy π ( a s). In off-policy learning, the Q ( s, a) function is learned from taking different actions (for example, random ... WebAn epsilon-greedy policy is one that has a probability of epsilon (or sometimes 1 - epsilon) of choosing the greedy action (i.e., the action with the maximal Q-value) or a random action. During execution, you usually just follow a greedy policy. You never interpret the Q-values as a probability distribution during vanilla Q-learning, ...
