MLP: Allow one-hot encoded dependent var for classification
JIRA:MADLIB-1222
MLP currently automatically encodes categorical variables for
classification but does not allow already encoded arrays for dependent
variables in mlp_classification. This commit lets users have an already
encoded array for the dependent variable and train a model.
You can merge this pull request into a Git repository by running:
$ git pull https://github.com/madlib/madlib

> Key: MADLIB-1222
> URL: https://issues.apache.org/jira/browse/MADLIB-1222
> Project: Apache MADlib
> Issue Type: New Feature
> Components: Module: Neural Networks
> Reporter: Nandish Jayaram
> Priority: Major
> Fix For: v1.14
>
>
> MLP currently only supports scalar dependent variables for MLP
> classification. If a user has already one-hot encoded categorical variables
> the dependent variable will be an array, and hence unusable with
> mlp_classification. This feature request is to allow the use of one-hot
> encoded array for dependent vars in MLP classification.
