Edward J. Yoon commented on HAMA-760:
-------------------------------------

I think you missed adding new CostEntropy class.

> 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.
