WebMar 18, 2024 · AUC is the area under the ROC curve, it measures how well a model distinguishes between two classes. The higher the better. AUC is classification-threshold-invariant and scale-invariant. GINI is just an adjustment to AUC so that a perfectly random model scores 0 and a reversing model has a negative sign.
