The Relationship Between Precision-Recall and ROC Curves中证明了以下两条定理 定理1:对于一个给定的的数据集,ROC空间和PR空间存在一一对应的关系,因为二者包含完全一致的混淆矩阵。我们可以将ROC曲线转化为PR曲线,反之亦然。 定理2:对于一个给定数目的正负样本数据集,曲线 A 在 ROC 空间优于曲线 B ,当且仅当...
受试者工作曲线(receiver operator curves ,简称ROC曲线),它以试验的灵敏度(真阳性率)为纵坐标,以(1-特异度)(或假阳性率)为横坐标作图形成一条曲线,表达灵敏度与特异度之间的相互关系,是广泛应用于临床诊疗和人群筛检研究的一种统计方法。用于评价生物标志物(markers)的性能,即基于标记值是否超过阈值(c),诊断为...
