Frank McQuillan updated MADLIB-1227:
------------------------------------
Description:
Related to
https://issues.apache.org/jira/browse/MADLIB-1226
Add check to MLP classification code to check that the dependent var has been
1-hot encoded by accident, 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 not converge, or give
erroneous results, and giving no notification to the user about the problem.
