tf.keras.backend.categorical_crossentropy

tf.keras.backend.categorical_crossentropy(
    target,
    output,
    from_logits=False
)

Defined in tensorflow/python/keras/_impl/keras/backend.py.

Categorical crossentropy between an output tensor and a target tensor.

Arguments:

• target: A tensor of the same shape as output.
• output: A tensor resulting from a softmax (unless from_logits is True, in which case output is expected to be the logits).
• from_logits: Boolean, whether output is the result of a softmax, or is a tensor of logits.

Returns:

Output tensor.
