In some problems this can be hard, so -greedy is what we resort to. 4 Upper Con dence Bound Algorithms The popular algorithm that people use for bandit problems is known as UCB for Upper-Con dence Bound. It uses a principle called \optimism in the face of uncertainty," which broadly means that if you don’t know precisely what
WebOct 23, 2024 · Our bandit eventually finds the optimal ad, but it appears to get stuck on the ad with a 20% CTR for quite a while which is a good — but not the best — solution. This is a common problem with the epsilon-greedy strategy, at least with the somewhat naive way we’ve implemented it above.
Webε-greedy is the classic bandit algorithm. At every trial, it randomly chooses an action with probability ε and greedily chooses the highest value action with probability 1 - ε.

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 $\epsilon T = \Theta(T)$. litree madeinchinaWebEpsilon greedy is the linear regression of bandit algorithms.
