【Reinforcement Learning】 Epsilon-Greedy Action Selection

Greedy algorithms can be characterized as being 'short sighted', and also as 'non-recoverable'. They are ideal only for problems that have an 'optimal substructure'. Despite this, for many simple problems, the best-suited algorithms are greedy. It is important, however, to note that the greedy algorithm can be used as a selection algorithm to prioritize options within a search, or branch-and-bound algorithm. There are a few variations to the greedy algorithm: WebConsider applying to this problem a bandit algorithm using ε-greedy action selection, sample-average action-value estimates, and initial estimates of Q1(a) = 0, for all a. Suppose the initial sequence of actions and rewards is A1 =1,R1 =1,A2 =2,R2 =1,A3 =2,R3 =2,A4 =2,R4 =2, A5 = 3, R5 = 0. On some of these time steps the ε case may have ... incline treadmill walking weight loss results

WebSep 28, 2024 · Greedy action selection can get stuck in an non-optimal choice: The initial value estimate of one non-optimal action is relatively high. The initial value estimate of the optimal action is lower than the true value of that non-optimal action.
