tensorflow::ops::SoftmaxCrossEntropyWithLogits

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).
