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. Web- $\Large \alpha$ (alpha) is the learning rate ($0 < \alpha \leq 1$) - Just like in supervised learning settings, $\alpha$ is the extent to which our Q-values are being updated in every iteration. - $\Large \gamma$ (gamma) is the discount factor ($0 \leq \gamma \leq 1$) - determines how much importance we want to give to future rewards.
