BCELoss vs BCEWithLogitsLoss

[ptrblck]

@Santosh-Gupta

Just to be super duper clear, do Not pass inputs through a sigmoid if using BCEWithLogitsLoss ?

Yes.

• logits → nn.BCEWithLogitsLoss
• logits → sigmoid → nn.BCELoss

@Santosh-Gupta

And for the outputs, just use ‘1’ for True classes, or ‘0’ for the false classes?

That would be the standard definition, but you can basically define True/False, Positive/Negative as you wish.
