Binary crossentropy between an output tensor and a target tensor.

`k_binary_crossentropy(target, output, from_logits = FALSE)`

A tensor.

- target
A tensor with the same shape as

`output`

.- output
A tensor.

- from_logits
Whether

`output`

is expected to be a logits tensor. By default, we consider that`output`

encodes a probability distribution.

This function is part of a set of Keras backend functions that enable lower level access to the core operations of the backend tensor engine (e.g. TensorFlow, CNTK, Theano, etc.).
