>             Project: Spark
>          Issue Type: Umbrella
>          Components: ML
>    Affects Versions: 1.5.0
>            Reporter: Alexander Ulanov
>            Priority: Minor

> Goal: Implement various types of autoencoders 
> Requirements:
> 1)Basic (deep) autoencoder that supports different types of inputs: binary, real in [0..1].
real in [-inf, +inf] 
> 2)Sparse autoencoder i.e. L1 regularization. It should be added as a feature to the MLP
and then used here 
> 3)Denoising autoencoder 
> 4)Stacked autoencoder for pre-training of deep networks. It should support arbitrary
network layers:
