Actually there is no need for that. PyTorch has BCELoss which stands for Binary Cross Entropy Loss. ... Sigmoid() # initialize sigmoid layer loss = nn.
16.09.2020 · the sigmoid()into that part of your loss function, rather than into your model. (It is numerically better to apply the sigmoid()to your logits in the MSE part of your loss, that to try to undo a sigmoid()in the CrossEntropyLosspart of your loss.) (BCELossis not appropriate for the classification part of your model
18.04.2017 · I am trying to find the equivalent of sigmoid_cross_entropy_with_logits loss in Pytorch but the closest thing I can find is the MultiLabelSoftMarginLoss. Can someone direct me to the equivalent loss? If it doesn’t exist, that information would be useful as well so I …
16.09.2020 · Due to the architecture (other outputs like localization prediction must be used regression) so sigmoid was applied to the last output of the model (f.sigmoid (nearly_last_output)). And for classification, yolo 1 also use MSE as loss. But as far as I know that MSE sometimes not going well compared to cross entropy for one-hot like what I want.
CrossEntropyLoss class torch.nn.CrossEntropyLoss(weight=None, size_average=None, ignore_index=- 100, reduce=None, reduction='mean', label_smoothing=0.0) [source] This criterion computes the cross entropy loss between input and target. It is useful when training a classification problem with C classes.
