Python中的sklearn.metrics.mean_square_error是Sklearn库中的一个函数,用于计算均方误差(Mean Square Error,简称MSE)。 MSE是评估预测模型精度的常用指标之一,它衡量的是实际值与预测值之间的差异,具体地说,MSE是预测值与实际值差的平方和的平均数。 若预测模型中有n个数据样本,预测值为$y_i$,实际值为$\hat...

from sklearn.metrics import roc_auc_score auc_score = roc_auc_score(y_test,y_pred) 说明: y_pred即可以是类别,也可以是概率。 roc_auc_score直接根据真实值和预测值计算auc值,省略计算roc的过程。 1# -*- coding: utf-8 -*-2"""3# 作者:wanglei52054# 邮箱:wanglei5205@126.com5# 博客:http...
