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. |
