tf.raw_ops.SoftmaxCrossEntropyWithLogits
Computes softmax cross entropy cost and gradients to backpropagate.
tf.raw_ops.SoftmaxCrossEntropyWithLogits( features, labels, name=None )
Inputs are the logits, not probabilities.
Args | |
---|---|
features | A Tensor . Must be one of the following types: half , bfloat16 , float32 , float64 . batch_size x num_classes matrix |
labels | A Tensor . Must have the same type as features . batch_size x num_classes matrix The caller must ensure that each batch of labels represents a valid probability distribution. |
name | A name for the operation (optional). |
Returns | |
---|---|
A tuple of Tensor objects (loss, backprop). | |
loss | A Tensor . Has the same type as features . |
backprop | A Tensor . Has the same type as features . |
