Greedy actions
WebDec 3, 2015 · 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 possible actions. For further details, see sections 5.4 and 5.6 of the book Reinforcement Learning: An Introduction by Barto and Sutton, first edition. WebApr 29, 2024 · Then whichever action is selected, the reward is less than the starting estimates, and the learner switches to other actions. The result is that all actions are tried several times before the value estimates converge. The system does a fair exploration even if greedy actions are selected all the time. Upper Confidence Bound

WebGoing through more or less all recent publications I always find the use of epsilon greedy as the action selection strategy. On the other hand Sutton (as far as I remember) suggested as early as in the 90's that softmax is superior to epsilon greedy in many cases, since it is more efficient in exploring therefore learning faster. WebApr 17, 2024 · Complete your Q-learning agent by implementing epsilon-greedy action selection in getAction, meaning it chooses random actions an epsilon fraction of the time, and follows its current best Q-values otherwise. Note that choosing a random action may result in choosing the best action ...

The fourth action, A4=2, is an exploration because the values of Q are Q(3)= −1,−0.5,0,0, and if we had followed the greedy method, we would have chosen action 3 or 4.
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 ...

WebThis approach, that is option 2, has a name, is called an Epsilon-greedy policy, where here Epsilon is 0.05 is the probability of picking an action randomly.
