In machine learning, we often use AUC-ROC (Area Under the Receiver Operating Characteristic Curve) to evaluate the performance of a classification model.
四舍五入来归纳预测的数据,即>=0.5为1,<0.5为0,如此得到的混淆矩阵如下:计算的结果:真阳性率 = 3 / (3+2) = 0.6 伪阳性率 = 3 / (3+4) = 0.43...AUC(Area Under Curve)是机器学习中二分类模型的一个评价指标。定义为ROC曲线中下的面积,但我们先不管定义。 简单解释,AUC代表的是真阳性率(实际...

The AUC-ROC curve is an important performance metric in machine learning because it provides a comprehensive measure of a model's ability to distinguish between positive and negative cases.It is particularly useful when the data is imbalanced, meaning that one class is much more prevalent than ...

AUC, or Area Under Curve, is a metric for binary classification. It’s probably the second most popular one, after accuracy. Unfortunately, it’s nowhere near as intuitive. That is, until you have read this article. Accuracy deals with ones and zeros, meaning you either got the class labe...
