WebApr 8, 2024 · Binary Cross Entropy (BCE) Loss Function. Just to recap of BCE: if you only have two labels (eg. True or False, Cat or Dog, etc) then Binary Cross Entropy (BCE) is the most appropriate loss function. Notice in the mathematical definition above that when the actual label is 1 (y(i) = 1), the second half of the function disappears. good way to cook broccoliWebsmooth – Smoothness constant for dice coefficient ignore_index – Label that indicates ignored pixels (does not contribute to loss) eps – A small epsilon for numerical stability to avoid zero division error (denominator will be always greater or equal to eps) Shape y_pred - torch.Tensor of shape (N, C, H, W) good way to end a speechWebFeb 18, 2024 · Imagine that I have a multi-class, multi-label classification problem; my imbalanced one-hot coded dataset includes 1000 images with 4 labels with the following frequencies: class 0: 600, class 1: 550, class 2: 200, class 3: 100.
