I understand that for image classification model, we have RGB input = [h,w,3] and label or ground truth = [h,w,n_classes]. We then use the trained model to create output then compute loss.

Webclass torch.nn.NLLLoss(weight=None, size_average=None, ignore_index=- 100, reduce=None, reduction='mean') [source] The negative log likelihood loss. It is useful to train a classification problem with C classes. If provided, the optional argument weight should be a 1D Tensor assigning weight to each of the classes. WebAn activation function to apply after the final convolution layer. Available options are “sigmoid”, “softmax”, “logsoftmax”, “tanh”, “identity”, callable and None. Dictionary with parameters of the auxiliary output (classification head). Auxiliary output is build on top of encoder if aux_params is not None (default). gowaterusers.com
