OK, I will do that.

> > 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.
