WebMar 24, 2024 · Epsilon greedy is the linear regression of bandit algorithms. Much like linear regression can be extended to a broader family of generalized linear models, there are several adaptations of the epsilon greedy algorithm that trade off some of its simplicity for better performance. One such improvement is to use an epsilon-decreasing strategy. WebEpsilon-greedy. One of the simplest and most frequently used versions of the multi-armed bandit is the epsilon-greedy approach. Thinking back to the concepts we just discussed, …
WebIf $\epsilon$ is a constant, then this has linear regret. Suppose that the initial estimate is perfect. Then you pull the `best' arm with probability $1-\epsilon$ and pull an imperfect arm with probability $\epsilon$, giving expected regret $\epsilon T = \Theta(T)$.
