Web1 day ago · The Receiver Operating Characteristic curve (ROC curve) is a graphical tool that assesses the accuracy of a classification method. Nowadays it is a well–accepted technique for this purpose. In this sense, given a binary classifier, the ROC curve reflects how well this classifier discriminates between two different groups or classes. ... WebThe area under a receiver operating characteristic (ROC) curve, abbreviated as AUC, is a single scalar value that measures the overall performance of a binary classifier (Hanley and McNeil 1982 ). The AUC value is within the range [0.5–1.0], where the minimum value represents the performance of a random classifier and the maximum value would ...
