新的确定性算法在机器学习中实现了最优多校准

研究人员开发了一种新颖的确定性算法用于机器学习中的多校准,解决了关于最优样本复杂度是否需要随机化的开放性问题。该新算法实现了 $\varepsilon$-多校准的最小最大最优速率 $\widetilde O(\varepsilon^{-3})$,这一属性对于可信赖的 AI 应用至关重要。该工作还扩展到结果不可区分性的确定性预测器,为 omnipredictors 和 pan predictors 提供了最优解决方案。 AI

影响 该研究通过提供一种确定性的多校准方法,推进了可信赖机器学习的理论基础,有望带来更可靠的 AI 系统。

    A model is multicalibrated on a collection of group weights $G$ if it is calibrated -- i.e. unbiased even conditional on its prediction -- not just overall, but also after reweighting contexts by each $g \in G$. It is a useful property for many downstream applications and is a ba…
