Alexander Ulanov commented on SPARK-2623:
-----------------------------------------

Relevant PR: artificial neural networks https://github.com/apache/spark/pull/1290. Also, I've
implemented alphas version of stacked autoencoder here https://github.com/avulanov/spark/tree/autoencoder

>             Project: Spark
>          Issue Type: New Feature

> We would like to add parallel implementation of  Stacked Auto Encoder (Deep Learning
) algorithm to Spark MLLib.
> SAE is one of the most popular Deep Learning algorithms. It has achieved successful benchmarks
in MNIST hand written classifications, Google's ICML2012 "cat face" paper (http://icml.cc/2012/papers/73.pdf),
etc.
> Our focus is to leverage the RDD and get the SAE with the following capability with ease
of use for both beginners and advanced researchers:
> 1, multi layer SAE deep network training and scoring.
> 2, unsupervised feature learning.
> 3, supervised learning with multinomial logistic regression (softmax).
