Computes binary cross-entropy loss between target and output tensor.
Source:R/ops.R
op_binary_crossentropy.Rd
The binary cross-entropy loss is commonly used in binary classification tasks where each input sample belongs to one of the two classes. It measures the dissimilarity between the target and output probabilities or logits.
Arguments
- target
The target tensor representing the true binary labels. Its shape should match the shape of the
output
tensor.- output
The output tensor representing the predicted probabilities or logits. Its shape should match the shape of the
target
tensor.- from_logits
(optional) Whether
output
is a tensor of logits or probabilities. Set it toTRUE
ifoutput
represents logits; otherwise, set it toFALSE
ifoutput
represents probabilities. Defaults toFALSE
.
Examples
target <- op_array(c(0, 1, 1, 0))
output <- op_array(c(0.1, 0.9, 0.8, 0.2))
op_binary_crossentropy(target, output)
