Jun 10, 2019 · I am trying to do a multi-class classification in pytorch. The code runs fine, but the accuracy is not good. I was wondering if my code is correct? The input to the model is a matrix of 2000x100 and the output is a 1D tensor with the index of the label ex: tensor([2,5,31,…,7]) => 2000 elements # another multi-class classification class MultiClass(nn.Module): def __init__(self, x_dim, z_dim ...

04.11.2020 · With PyTorch, to do multi-class classification, you encode the class labels using ordinal encoding (0, 1, 2, . .) and you don’t explicitly apply any output activation, and you use the highly specialized (and completely misnamed) CrossEntropyLoss() function. When I was first learning how to use PyTorch, this new scheme baffled me.
