Is anybody still working on an RBM algorithm for MLlib? I have a Scala 
implementation of an RBM that I would like to contribute.

Hi Alexander,
I forked your latest version of 
https://github.com/avulanov/spark/tree/ann-interface-gemm.
I would like to contribute to the MLlib by adding an implementation of a DBN. 
I have a scala implementation working right now. I am going to try and merge it 
with your ANN models. 
Thanks
Janani

> Goal: Implement various types of artificial neural networks
> Motivation: deep learning trend
> Requirements: 
> 1) Basic abstractions such as Neuron, Layer, Error, Regularization, Forward 
> and Backpropagation etc. should be implemented as traits or interfaces, so 
> they can be easily extended or reused
> 2) Implement complex abstractions, such as feed forward and recurrent networks
> 3) Implement multilayer perceptron (MLP), convolutional networks (LeNet), 
> autoencoder (sparse and denoising), stacked autoencoder, restricted  
> boltzmann machines (RBM), deep belief networks (DBN) etc.
> 4) Implement or reuse supporting constucts, such as classifiers, normalizers, 
> poolers,  etc.
