WebMay 20, 2024 · The expression for Binary Crossentropy is the same as mentioned in the question. N refers to the batch size. We now implement BCE on our own. First, we clip the outputs of our model, setting max to tf.keras.backend.epsilon () and min to 1 - tf.keras.backend.epsilon (). The value of tf.keras.backend.epsilon () is 1e-7. WebOur solution is that BCELoss clamps its log function outputs to be greater than or equal to -100. This way, we can always have a finite loss value and a linear backward method. Parameters: weight ( Tensor, optional) – a manual rescaling weight given to the loss of each batch element. If given, has to be a Tensor of size nbatch.
