均值漂移多臂老虎机最佳臂识别研究
Get the story
2026年10月8日,arXiv(Statistics Machine Learning)发表题为《均值漂移多臂老虎机中的最佳臂识别》的论文。论文提出 Shifting Means 设定:K 个臂的平均奖励可随时间整体漂移,仅臂间差距 Δ 保持稳定,目标是在高概率识别最佳臂的同时最小化样本复杂度。作者证明采用 GLRT 停止规则的算法(含 Track-and-Stop)在时变漂移下会失效,并提出 Importance Weights for Shifting Means(ISM)方法作为替代。该研究为一手论文,目前未见后续验证或同行评议结果。

论文提出 Shifting Means 设定:K 个臂的平均奖励可随时间整体漂移,仅臂间差距 Δ 保持稳定,目标是高概率识别最佳臂并最小化样本复杂度。作者证明采用 GLRT 停止规则的算法(含 Track-and-Stop)在时变漂移下失效,转而提出 Importance Weights for Shifting Means(ISM)。
