WebDec 15, 2024 · I have a question about how to update the Q-function in Q-learning and SARSA. Here ( What are the differences between SARSA and Q-learning?) the following updating formulas are given: Q-Learning Q ( s, a) = Q ( s, a) + α ( R t + 1 + γ max a Q ( s ′, a) − Q ( s, a)) SARSA Q ( s, a) = Q ( s, a) + α ( R t + 1 + γ Q ( s ′, a ′) − Q ( s, a)) WebOct 31, 2024 · 5.6K Followers A Technology Enthusiast who constantly seeks out new challenges by exploring cutting-edge technologies to make the world a better place!

Convergence speed comparison of Q-learning and SARSA (λ).
WebBoth Q-learning and SARSA have an n-step version. We will look at n-step learning more generally, and then show an algorithm for n-step SARSA. The version for Q-learning is similar. Discounted Future Rewards (again) When calculating a discounted reward over a trace, we simply sum up the rewards over the trace: WebThe Q-learning algorithm, as the most-used classical model-free reinforcement learning algorithm, has been studied in anti-interference communication problems [5,6,7,8,9,10,11]. … how liver disease cause anemia
