the positive case), and TPR is very high, assuming threshold=0.1, fpr=tpr= 1, you can draw the first point in the coordinate system (threshold); In the same vein, with the increase of the FPR and TPR will gradually decrease, and finally even 0. The shape of the curve is usually as follows:If the classifier works well, the curve should be close to the upper-left corner (TPR large, FPR small).The AUC (area under Curve) is defined as the size of the ROC curve, which obviously does not have a value
