tensorflow::ops::SoftmaxCrossEntropyWithLogits
#include <nn_ops.h>
Computes softmax cross entropy cost and gradients to backpropagate.
Summary
Inputs are the logits, not probabilities.
Args:
- scope: A Scope object
- features: batch_size x num_classes matrix
- labels: batch_size x num_classes matrix The caller must ensure that each batch of labels represents a valid probability distribution.
Returns:
Output loss: Per example loss (batch_size vector).Output backprop: backpropagated gradients (batch_size x num_classes matrix).
