新的iAUC框架通过不确定性感知增强风险预测评估

作者 PulseAugur 编辑部 · [1 个来源] ·

研究人员开发了一个新的框架，用于评估包含不确定性的风险预测模型。这种基于区间（interval-based）的AUC (iAUC) 方法将传统的ROC分析扩展到处理区间值预测，后者自然地表示不确定性。该框架将排序分解为自信正确、模糊和自信错误类别，提供了与区间覆盖相关的鉴别性能的理论界限。在包括MIMIC-IV死亡率预测在内的临床数据上进行的实验表明，具有相似点AUC的模型可以表现出不同的不确定性感知特征，有助于模型选择和基于阈值的弃权。 AI

    Extending ROC Analysis to Uncertainty-Aware Risk Prediction with an Interval-Based AUC (iAUC)

    arXiv:2602.04775v2 Announce Type: replace Abstract: In high-stakes risk prediction, interval-valued predictions provide a natural way to represent predictive uncertainty. However, standard evaluation tools such as the receiver operating characteristic (ROC) curve and the area und…
