WebbAUC在机器学习领域中是一种模型评估指标。根据维基百科的定义，AUC(area under the curve)是ROC曲线下的面积。所以，在理解AUC之前，要先了解ROC是什么。而ROC的计算又需要借助混淆矩阵，因此，我们先从混淆矩阵开始谈起。 WebbUnder a standard binary classification setting with possible model misspecification, we study the problem of estimating general Receiver Operating Characteristic (ROC) curve, which is an arbitrary set of false positive rate (FPR) and true positive rate (TPR) pairs. We formally introduce the notion of \textit {optimal ROC curve} over a general ...

Receiver Operating Characteristic (ROC) Curves – ST494
