---------------------------------------
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.
