内容简介：

This talk explores the integration of safety into efficiency in sequential decision-making for online experimentation, specifically within a stochastic multi-armed bandit setting. Previous work mostly focuses on “optimality” of sequential decisions -- achieving efficiency by minimizing regret expectation. However, maintaining “safety” -- controlling the regret tail risk, is essential in critical applications. This work provides a detailed characterization of the trade-off between optimality and safety. This is joint work with Feng Zhu and David Simchi-Levi.
