WebbMultilabel(多标签分类)metrics：hamming loss，F score 这里对用到的三个metrics做一个总结。 首先明确一下多标签（multilabel）分类和多类别（multiclass）分类的不同：multiclass仅仅表示输出的类别大于2个，这样可以和一般的二分类（binary）区别开，但每一个输入x仅仅对应一个输出标签。 Webbsklearn.metrics.silhouette_score(X, labels, *, metric='euclidean', sample_size=None, random_state=None, **kwds) [source] ¶.

How to apply the sklearn method in Python for a machine

Webb9 okt. 2015 · If you use the default score it works, as you can see above. So you probably need to look at your predictions and understand why they are continuous (i.e. use a classifier instead of regression). Or use a different score. As an aside, if you run the regression with only one set of (column of) y values, you still get an error.
