English(EN) Overcoming Dependent Censoring in the Evaluation of Survival Models

新的依赖性Brier分数改进了生存模型评估

作者 PulseAugur 编辑部 · [1 个来源] ·

研究人员开发了一种名为依赖性Brier分数的新指标，以解决当事件时间和审查时间不独立时生存模型评估中的挑战。该分数基于阿基米德联结和联结图估计器，为其边际时间估计器提供了稳定性和渐近正态性。在对12个数据集的评估中，与传统的审查权重倒数（IPCW）方法相比，所提出的指标显示估计误差平均减少了12-16%。 AI

影响 引入了一种新颖的统计方法来评估生存模型，有可能提高依赖此类模型进行事件发生时间预测的AI系统的准确性。

    克服生存模型评估中的依赖性审查

    arXiv:2502.19460v4 Announce Type: replace Abstract: Dependent censoring occurs when the event time and censoring time are not conditionally independent given the observed covariates. This complicates survival model evaluation because widely used metrics, such as the Brier score, …
