WebFeb 16, 2024 · In those (Reinforcement Learning 2: 2016) they show the exploration function in the q-val update step. This is consistent with what I extrapolated from the book's discussion on value iteration methods but not with what the book shows for Q-Learning (remember the book uses the exploration function in the argmax instead). WebQ- and V-learning are in the context of Markov Decision Processes. A MDP is a 5-tuple (S, A, P, R, γ) with S is a set of states (typically finite) A is a set of actions (typically finite) P(s, s ′, a) = P(st + 1 = s ′ st = s, at = a) is the probability to get from state s to state s ′ with action a. officemate migration
