WebThe policy. a = argmax_ {a in A} Q (s, a) is deterministic. While doing Q-learning, you use something like epsilon-greedy for exploration. However, at "test time", you do not take epsilon-greedy actions anymore. "Q learning is deterministic" is not the right way to express this. One should say "the policy produced by Q-learning is deterministic ...
