             Summary: Add Cross Entropy loss computation
                 Key: SINGA-184
                 URL: https://issues.apache.org/jira/browse/SINGA-184
             Project: Singa
          Issue Type: New Feature
            Reporter: Zheng Kaiping


Implement Cross Entropy loss.

Cross Entropy loss accepts the prediction from the neural net and the ground truth from the
training data. It outputs a scalar loss value for each data sample and computes the gradient
of the loss value w.r.t the prediction value through back propagation.
