Is auc better for binary classifications
WebAUC: Area Under the Curve, or AUC, is a metric used to assess how well a binary classification model performs. It is calculated by comparing the true positive rate at various categorization criteria against the false positive rate. The area under the curve of this figure is known as the AUC.
