What Is Multi-Label Classification

Multi-Label Classification

In fact, the correct way of denoting a target for class 0+2 (example from line 7) should be to replace line 16: labels.append([1, 0, 1]) with. labels.append([0,2,-1]) (as a side note, line 20 should have if category == (1, 1): to match the description at line 9)

Hello everyone. How can I do multiclass multi label classification in Pytorch? Is there a tutorial or example somewhere that I can use?

17.10.2018 · I have a multi-label classification problem. I have 11 classes, around 4k examples. Each example can have from 1 to 4-5 label. At the moment, i'm training a classifier separately for each class with log_loss. As you can expect, it is taking quite some time to train 11 classifier, and i would like to try another approach and to train only 1 ...

Oct 17, 2018 · Here's example code: import torch batch_size = 2 num_classes = 11 loss_fn = torch.nn.BCELoss() outputs_before_sigmoid = torch.randn(batch_size, num_classes) sigmoid_outputs = torch.sigmoid(outputs_before_sigmoid) target_classes = torch.randint(0, 2, (batch_size, num_classes)) # randints in [0, 2).
