WebMar 31, 2024 · Q-Learning Overview In Q-Learning we build a Q-Table to store Q values for all possible combinations of state and action pairs. It is called Q-Learning because it represents the quality of a certain action an agent can take in a provided space. The agents use a Q-table to choose the best action which gives maximum reward to the agent.

WebFeb 13, 2024 · The essence is that this equation can be used to find optimal q∗ in order to find optimal policy π and thus a reinforcement learning algorithm can find the action a that maximizes q∗ (s, a). That is why this equation has its importance. The Optimal Value Function is recursively related to the Bellman Optimality Equation. WebMoreover, note that the proofs mentioned above are only applicable to the tabular versions of Q-learning. If you use function approximation, Q-learning (and other TD algorithms) may not converge. Nevertheless, there are cases when Q-learning combined with function approximation converges.
