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

Alexander Ulanov created SPARK-10408:
----------------------------------------

             Summary: Autoencoder
                 Key: SPARK-10408
                 URL: https://issues.apache.org/jira/browse/SPARK-10408
             Project: Spark
          Issue Type: Improvement
          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
