Softmax is combined with Cross-Entropy-Loss to calculate the loss of a model. Unfortunately, because this combination is so common, it is often abbreviated. Some are using the term Softmax-Loss, whereas PyTorch calls it only Cross-Entropy-Loss.

The latter is useful for higher dimension inputs, such as computing cross entropy loss per-pixel for 2D images. The target that this criterion expects should contain either: Class indices in the range [ 0 , C − 1 ] [0, C-1] [ 0 , C − 1 ] where C C C is the number of classes; if ignore_index is specified, this loss also accepts this class index (this index may not necessarily be in the ...

29.06.2021 · Hello, My network has Softmax activation plus a Cross-Entropy loss, which some refer to Categorical Cross-Entropy loss. See: In binary classification, do I need one-hot encoding to work in a network like this in PyTorch? I am using Integer Encoding. Just as matter of fact, here are some outputs WITHOUT Softmax activation (batch = 4): outputs: tensor([[ 0.2439, 0.0890], [ …

17.03.2020 · Hi all, I am a newbie to pytorch and am trying to build a simple claasifier by my own. I am trying to train a tensor classifier with 4 classes, the inputs are one dimensional tensors with a length of 1000. This is the architecture of my neural network, I have used BatchNorm layer: class Net(nn.Module): def __init__(self): super(Net, self).__init__() self.conv1 = nn.Conv1d(1, 6, 5) …

Each of the variables train_batch, labels_batch, output_batch and loss is a PyTorch Variable and allows derivates to be automatically calculated.. All the other code that we write is built around this- the exact specification of the model, how to fetch a batch of data and labels, computation of the loss and the details of the optimizer.
