Binary classification pytorch loss
WebMay 20, 2024 · Binary Cross-Entropy Loss (BCELoss) is used for binary classification tasks. Therefore if N is your batch size, your model output should be of shape [64, 1] and your labels must be of shape [64] .Therefore just squeeze your output at the 2nd dimension and pass it to the loss function - Here is a minimal working example WebDec 4, 2024 · For binary classification (say class 0 & class 1), the network should have only 1 output unit. Its output will be 1 (for class 1 present or class 0 absent) and 0 (for class 1 …

It is possible to consider binary classification as 2-class-classification and apply CE loss with label smoothing. But I did not want to convert input shape as (2, batch) and target's dtype. So I implemented label smoothing to BCE loss by myself ...
