Multi-Class Classification Using PyTorch, Part 1: New Best Practices
WebDec 4, 2024 · Finally you can use the torch.nn.BCELoss: criterion = nn.BCELoss () net_out = net (data) loss = criterion (net_out, target) This should work fine for you. You can also use torch.nn.BCEWithLogitsLoss, this loss function already includes the sigmoid function so … WebJul 19, 2024 · FInally, we apply our softmax classifier (Lines 32 and 33). The number of in_features is set to 500, ... (which is the equivalent to training a model with an output Linear layer and an nn.CrossEntropyLoss loss). Basically, PyTorch allows you to implement categorical cross-entropy in two separate ways. Web2. Building a PyTorch classification model: Here we'll create a model to learn patterns in the data, we'll also choose a loss function, optimizer and build a training loop specific to classification. 3.
