             Summary: In MLP classification with mini-batch, check for 1-hot 
encoding of dependent variable
                 Key: MADLIB-1227
             Project: Apache MADlib
          Issue Type: Improvement
            Reporter: Frank McQuillan
             Fix For: v1.14

Related to

Add check to MLP classification code to check that the dependent var has been 
1-hot encoded, and error out if that is not the case.  

This is to avoid the case of passing INTs as dep var to MLP that have not been 
1-hot encoded and having it run classification and give no results, or 
erroneous results.
