-------------------------------------
I think you missed adding new CostEntropy class.
> Add new features to existing Multi Layer Perceptron
> ---------------------------------------------------

> Key: HAMA-760
> URL: https://issues.apache.org/jira/browse/HAMA-760
> Project: Hama
> Issue Type: New Feature

>
> Current MultiLayerPerceptron has only implemented the basic features of a
> Multi Layer Perceptron.
> There are still several features need to be implemented.
> In the next step the following features should be added:
> 1) add more cost functions such as cross entropy.
> 2) add momentum and regularization.
> 3) make the training method in MLP be public to allow user to use MLP in a
> standalone algorithm.
> 4) add more test cases on other applications, at least one with regression
> and one with classification.
