[jira] [Commented] (SPARK-10408) Autoencoder

    [ https://issues.apache.org/jira/browse/SPARK-10408?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16002326#comment-16002326 ] 

Nick Pentreath commented on SPARK-10408:
----------------------------------------

What is the status here? I think it's fairly safe to say that it's unlikely that Spark will support much in the way of deep learning itself. 

That said there may still be an argument for adding the {{MLPRegressor}} and an autoencoder - but I'm concerned we lack the review and maintenance bandwidth currently.

> 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
