PySpark 中的 MulticlassClassificationEvaluator 和 MultilabelClassificationEvaluator 有什么区别?

What is the difference between MulticlassClassificationEvaluator and MultilabelClassificationEvaluator in PySpark?

MulticlassClassificationEvaluator and MultilabelClassificationEvaluator 是 PySpark 中的两个(许多)分类算法评估器。 我找不到/不明白这两者之间的区别。

first one is for evaluation of the models that classifies given data into a specific single class (label), but model works with multiple classes (labels) (see wikipedia)。例如,您可以将网站分类为在线商店、商业、游戏、健康等。

second is for case when the data may belong to multiple classes and multiple labels (see wikipedia)。网站的继续示例,例如,在线销售药房的网站可能会被归类为“在线商店”和“健康”
