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.
