WebMar 24, 2024 · In a multi-armed bandit problem, the agent initially has none or limited knowledge about the environment. The agent can choose to explore by selecting an action with an unknown outcome, to get more information about the environment. ...

WebMay 19, 2024 · Sorted by: 5. We have: k different arms/"actions" to select. A probability of ϵ to select an arm uniformly at random. A probability of 1 − ϵ to straight up select the "best" arm according to our current value estimates (this is the arm corresponding to i = arg. . max j = 1, …, K μ ^ j ( t) ). The last point above tells you already ...
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 $\epsilon T = \Theta(T)$. list of famous deistsWebAug 28, 2016 · Since we have 10-arms, the Random strategy pulls the optimal arm in only 10% of pulls. Greedy strategy locks onto the optimal arm in only 20% of pulls. The \(\epsilon\)-Greedy strategy quickly finds the optimal arm but only pulls it 60% of the time.
