I am trying to do multiclass classification for the sentence pair task. I uploaded my custom dataset of train and test separately in the hugging face data set and trained my model and tested it and was trying to see the f1 score and accuracy. I tried fromdatasetsimportload...
OneVsOneClassifier为每一个类拟合一个分类器。在预测时,将选择得分最多的类。如果出现平局(在两个类别中具有相同得分),它将通过汇总基础二分类器计算的分类置信度来选择具有最高分类置信度(classification confidence)的类别。 由于该方法需要拟合n_classes * (n_classes - 1) / 2个分类器,因此该方法的复杂度为...
新闻稿B可以表示为[0,1,1],这就可以看成是multi-task classification问题了。 从这个例子也可以看出,Multilabel classification是一种特殊的multi-task classification问题。之所以说它特殊,是因为一般情况下,向量的元素可能会取多于两个值,比如同时要求预测年龄和性别,其中年龄有四个取值,而性别有两个取值。
