WebDec 22, 2024 · In DDQN you have two target Q, and two target policies, so the algorithm is still off-policy (sampling policy is e-greedy, target policies are greedy), while SARSA is on-policy (target policy = sampling policy). The trick in DDQN is that you use the max operator over Q2 (second critic) in the TD target for updating Q1 (first critic), and viceversa. WebOct 19, 2024 · Review & Introduction.
