WebCrossEntropyLoss. 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 logits and target. It is useful when training a classification problem with C classes. If provided, the optional argument ... WebJan 16, 2024 · It has a forward method that takes in two inputs; the output of the model and the target label. The forward method first converts the target label to a tensor of long integers. Then it creates an instance of the built-in PyTorch cross-entropy loss function and uses it to calculate the loss between the model’s output and the target label.
