English(EN) The Minimax Rate of Second-Order Calibration

新方法实现了二阶校准误差的最优速率

研究人员对二元分类中二阶校准误差的估计的 minimax 速率进行了表征,该误差衡量预测器的不确定性与标签概率方差的匹配程度。他们发现,使用特定的扰动核允许多项式回归达到 \(\tilde{O}(1/\sqrt{n})\) 的估计速率,这比现有方法有了显著改进。这项工作还为二阶 Platt 缩放提供了第一个有限样本保证,为任何高阶预测器的均值预测和认知方差估计提供了事后重新校准。 AI

影响 为分类模型中的不确定性量化建立了新的理论基准,可能提高 AI 系统的可靠性。

    二阶校准的Minimax率

    We characterize the minimax rate of estimating the second-order calibration error for binary classification, which quantifies whether a higher-order predictor's epistemic-uncertainty estimate matches the conditional variance of the label probability on its level sets. Our key obs…
