multi label cross entropy loss

python - What loss function for multi-class, multi-label ...
https://stats.stackexchange.com/questions/207794
I read that for multi-class problems it is generally recommended to use softmax and categorical cross entropy as the loss function instead of mse and I understand more or less why. For my problem of multi-label it wouldn't make sense to use softmax of course as each class probability should be independent from the other.

30.06.2017 · Hi, this is a general question about multi-label classification I have been thinking about: Multi-label classification for < 200 labels can be done in many ways, but here I consider two options: CNN (e.g. Resnet, VGG) + Cross entropy loss, the traditional approach, the final layer contains the same number of nodes as there are labels. Samples are taken randomly and …
