WebPlot Receiver Operating Characteristic (ROC) curve given an estimator and some data. RocCurveDisplay.from_predictions Plot Receiver Operating Characteristic (ROC) curve given the true and predicted values. det_curve Compute error rates for different probability thresholds. roc_auc_score Compute the area under the ROC curve. Notes WebROC curves typically feature true positive rate (TPR) on the Y axis, and false positive rate (FPR) on the X axis. This means that the top left corner of the plot is the “ideal” point - a FPR of zero, and a TPR of one. This is not very realistic, but it does mean that a larger Area Under the Curve (AUC) is usually better.
