Also known as: PR AUC Β· PR AUC (area Under The PR Curve) Β· Area Under The PR Curve
PR AUC stands for area under the precision-recall curve, a metric summarizing the trade-off between precision and recall across classification thresholds. It is especially useful for imbalanced classification problems where the positive class is rare.
Area under the interpolated precision-recall curve, obtained by plotting (recall, precision) points for different values of the classification threshold.
