WebDec 3, 2015 · In off-policy methods, the policy used to generate behaviour, called the behaviour policy, may be unrelated to the policy that is evaluated and improved, called the estimation policy. An advantage of this seperation is that the estimation policy may be deterministic (e.g. greedy), while the behaviour policy can continue to sample all … WebJan 23, 2024 · 1.
