WebWe propose a Thompson sampling algorithm, termed ExpTS, which uses a novel sampling distribution to avoid the under-estimation of the optimal arm. We provide a tight regret analysis for ExpTS, which simultaneously yields both the finite-time regret bound as well as the asymptotic regret bound. In particular, for a K K -armed bandit with ... Web1.2 Thompson Sampling In the most general setting, Thompson Sampling can be described as a natural Bayesian algorithm that plays an arm according to its probability of being the …
