Sampling column reports negative to positive class ratio after applying random undersampling, or “None” for case when no undersampling is applied
AUC stands for Area Under the Receiver Operating Characteristic Curve, SD stands for standard deviation reported for every metric, AUPRC stands for Area under the Precision-Recall Curve
