Determine how good an AUC is (Area under the Curve of ROC)
Websklearn.metrics.auc¶ sklearn.metrics. auc (x, y) [source] ¶ Compute Area Under the Curve (AUC) using the trapezoidal rule. This is a general function, given points on a curve. For computing the area under the ROC-curve, see roc_auc_score. For an alternative way to summarize a precision-recall curve, see average_precision_score.

WebMar 3, 2024 · As you observe, accuracy of this prediction has decreased to 79.2%, for the probability threshold value of 0.6 for the true class. TP, FP, TN and FN values are 677, 94, 307 and 851 respectively ... WebAUC简介. AUC（Area Under ROC Curve）从字面意思来说就是AUC的值等于处于ROC曲线下方的那部分面积之和。. 通常来说，AUC的值位于 [0.5,1]上，在AUC>0.5的情况 … WebArea under the curve = Probability that Event produces a higher probability than Non-Event. AUC=P (Event>=Non-Event) AUC = U 1 / (n 1 * n 2 ) Here U 1 = R 1 - (n 1 * (n 1 + 1) / 2) where U1 is the Mann Whitney U statistic and R1 is the sum of the ranks of predicted probability of actual event. It is calculated by ranking predicted probabilities ... cheryl callahan facebook
