WebSep 5, 2024 · The existing masked LM uses Softmax cross entropy (SCE), which is a function that is used for problems with a single correct answer. However, this function is difficult to use in the multi-hot LM proposed in this paper. ... Another loss function is binary cross entropy (BCE), which finds a loss value for multiple correct answers. ... WebJan 4, 2024 · Binary Cross Entropy (BCE) Loss Function. 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.
