, 在机器学习中，多元分类是将实例分配到多个（多于两个）类别中的其中一个（将实例分配到两个类别中的其中一个被称为）。 显然，分类算法可以分为二分类和多分类两种，而多分类算法可以通过将其转化为多个二分类来实现。 需要注意的是，多分类不应和相混淆：多标签分类可以为每个实例预测多个标签，即同一个实例可以同时被分配到多个类别。

While many classification algorithms (notably multinomial logistic regression) naturally permit the use of more than two classes, some are by nature binary algorithms; these can, however, be turned into multinomial classifiers by a variety of strategies. Multiclass classification should not be confused with multi-label classification, where multiple labels are to be predicted for each instance.els are to be predicted for each instance.
