Binary_cross_entropy not implemented for long
WebJun 22, 2024 · The loss function I am using is the CrossEntropyLoss implemented in pytorch, which is, according to the documents, a combination of logsoftmax and negative log likelihood loss (forgive me for not knowing much about them, all I know is that cross entropy is frequently used for classification). WebMar 11, 2024 · The binary cross entropy loss function is applied to most pixel-level segmentation tasks. However, when the number of pixels on the target is much smaller than the number of pixels in the background, that is, the samples are highly unbalanced, and the loss function has the disadvantage of misleading the model to seriously bias the …
