How to understand k-armed bandit example from Sutton

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. WebIn ε-greedy action selection, for the case of two actions and ε = 0.5, what is the probability thtat the greedy action is selected? Answer: 0.5 + 0.5 * 0.5 = 0.75. 50% of the times it'll be selected greedily (because it is the best choice) and half of the times the action is selected randomly it will be selected by chance. five night at pingas https://iaclean.com
