This criterion computes the cross entropy loss between input and target. It is useful when training a classification problem with C classes.

Learn how to use Binary Crossentropy Loss (nn.BCELoss) with your neural network in PyTorch, Lightning or Ignite. Includes example code.

Function that measures the Binary Cross Entropy between the target and input probabilities. See BCELoss for details. Parameters.

Function that measures the Binary Cross Entropy between the target and input probabilities. See BCELoss for details. input – Tensor of arbitrary shape as probabilities. target – Tensor of the same shape as input with values between 0 and 1. weight ( Tensor, optional) – a manual rescaling weight if provided it’s repeated to match input ...

05.05.2021 · Hi Everyone, I have been trying to replace F.binary_cross_entropy by my own binary cross entropy custom loss since I want to adapt it and make appropriate changes. I feel that having it as a custom loss defined would allow me to experiment with it more thoroughly and make desired changes to it. That being said, I double check whether my custom loss returns …
