Cross entropy is used for multiple class case and sum of inputs should be equal to 1. Formula is just negative sum of each label multiply by log of each prediction. – Kyrylo Polezhaiev Feb 11, 2024 at 10:50

WebBinary cross-entropy is used in binary classification problems, where a particular data point can have one of two possible labels (this can be extended out to multiclass … WebJul 12, 2024 · Are you using BinaryCrossEntropy or BinaryCrossEntroppyWithLogits? The first one expects probabilities so you should pass your output through a sigmoid. The second expects logits, so it could be any thing. Because of the error my guess is you are using the first one. – Umang Gupta Jul 13, 2024 at 9:32 WebApr 15, 2024 · Now, unfortunately, binary cross entropy is a special case for machine learning contexts but not for general mathematics cases.
