In the cases where we have two or more independent variables, we use the following steps to implement multiple regression using the sklearn module in python. If there are N independent variables namely X1, X2,X3
首先,引出例子: 已知三个feature,三个feature分别取值如下: feature1=[“male”, “female”] feature2=[“from Europe”, “from US”, “from Asia”] feature3=[“uses Firefox”, “uses Chrome”, “uses Safari”, “uses Internet Explorer”] 如果做普通数据处理,那么我们就按0,1,2,3进行编号就行...

In the multiclass case, the training algorithm uses the one-vs-rest (OvR) scheme if the ‘multi_class’ option is set to ‘ovr’, and uses the cross-entropy loss if the ‘multi_class’ option is set to ‘multinomial’. (Currently the ‘multinomial’ option is supported only by the ‘...
