hello, have you solved this problem?

[bimhud]

When having a large number of labels and the number of actual labels for each sample is small, the loss function needs to be re-considered, otherwise the accuracy is unreliable

hello have you solved this problem? I meet this problem too

When having a large number of labels and the number of actual labels for each sample is small, the loss function needs to be re-considered, otherwise the accuracy is unreliable

so I should change the loss function? should I modify the method of accuracy ?

我也遇到了同样的问题，实际的分类效果非常差

是的，我也遇到了，66个类别，准确率不能反映真实情况
