WebNov 15, 2024 · The ‘Q’ in Q-learning stands for quality. Quality here represents how useful a given action is in gaining some future reward. Q-learning Definition. Q*(s,a) is the expected value (cumulative discounted reward) of doing a in state s and then following the optimal policy. Q-learning uses Temporal Differences(TD) to estimate the value of Q*(s ...

WebA reward \(R_t\) is a feedback value. In indicates how well the agent is doing at step \(t\). The job of the agent is to maximize the cumulative reward. Reward Hypothesis: All goals can be described by the maximisation of expected cumulative reward.
