> Implementation of a Multilayer Perceptron (Neural Network)
>  - Learning by Backpropagation 
>  - Distributed Learning
> The implementation should be the basis for the long range goals:
>  - more efficent learning (Adagrad, L-BFGS)
>  - High efficient distributed Learning
>  - Autoencoder - Sparse (denoising) Autoencoder
>  - Deep Learning
>  
> ---
> Due to the overhead of Map-Reduce(MR) MR didn't seem to be the best strategy to distribute
the learning of MLPs.
> Therefore the current implementation of the MLP (see MAHOUT-976) should be migrated to
Hama. First all dependencies to Mahout (Matrix-Library) must be removed to get a standalone
MLP Implementation. Then the Hama BSP programming model should be used to realize distributed
learning.
> Different strategies of efficient synchronized weight updates has to be evaluated.
