"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. " - Binary_cross_entropy torch
