             Summary: Add independent_varname column for MLP/SVM predict functions
                 Key: MADLIB-1331
                 URL: https://issues.apache.org/jira/browse/MADLIB-1331
             Project: Apache MADlib
          Issue Type: Improvement
          Components: Module: Neural Networks, Module: Support Vector Machines
            Reporter: Nandish Jayaram
             Fix For: v2.0


The predict functions for MLP and SVM have a parameter named {{id}} in it, and the name of the independent variable is inferred from the model summary table. This poses a serious limitation; test data table is forced to follow a schema, where the independent variable column has the same name as what was in the training data table. This can cause issues when the consumer of an MLP/SVM model is not the producer of the model.

Acceptance:
1. Add a new parameter for independent variable.
2. Evaluate if {{id}} column from the current predict interface is required (think about grouping too.)
3. Find other modules that may have this issue, and raise new JIRAs if need be.
