sparse_categorical_crossentropy( output, target, from_logits=False )
Defined in tensorflow/contrib/keras/python/keras/backend.py
.
Categorical crossentropy with integer targets.
Arguments:
output: A tensor resulting from a softmax (unless `from_logits` is True, in which case `output` is expected to be the logits). target: An integer tensor. from_logits: Boolean, whether `output` is the result of a softmax, or is a tensor of logits.
Returns:
Output tensor.
