Classical bandit algorithms
Many variants of the problem have been proposed in recent years. The dueling bandit variant was introduced by Yue et al. (2012) to model the exploration-versus-exploitation tradeoff for relative feedback. In this variant the gambler is allowed to pull two levers at the same time, but they only get a binary feedback telling which lever provided the best reward. The difficulty of this problem stems from the fact that the gambler has no way of directly observi… WebOct 18, 2024 · A Unified Approach to Translate Classical Bandit Algorithms to the Structured Bandit Setting.
