---------------------------------------

             Summary: Move mean and standard deviation values to output table
                 Key: MADLIB-1285
                 URL: https://issues.apache.org/jira/browse/MADLIB-1285
             Project: Apache MADlib
          Issue Type: Improvement
          Components: Module: Neural Networks
            Reporter: Nandish Jayaram
             Fix For: v2.0


MLP standardizes data during training. The mean and standard deviation values for each feature, is stored in arrays in a separate table called output_table_standardization. This table also stores these mean and std_dev arrays for each group if MLP was called with grouping columns. This information could be moved to the output table instead.
