----------------------------------
Summary: Decision Tree's output summary table does not contain the
right list independent variables
Key: MADLIB-1029
URL: https://issues.apache.org/jira/browse/MADLIB-1029
Project: Apache MADlib
Issue Type: Bug
Components: Module: Decision Tree
Reporter: April Song
Decision Tree's output summary table does not contain the right list
independent variables.
Steps to reproduce:
select madlib.tree_train('abalone_2', -- source table
'adaboost_output_test', -- output model table
'rowid', -- id column
'sex', -- response
'length,diam,height,whole,shucked,viscera,shell,rings,color', -- features
NULL::text, -- exclude columns
'gini', -- split criterion
NULL::text, -- no grouping
NULL::text, -- no weights
5, -- max depth
3, -- min split
1, -- min bucket
10
);
gpadmin=# select * from adaboost_output_test_summary;
