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

             Summary: Allow to use intercept in Ridge and Lasso
                 Key: SPARK-1599
                 URL: https://issues.apache.org/jira/browse/SPARK-1599
             Project: Spark
          Issue Type: Sub-task
          Components: MLlib
    Affects Versions: 1.0.0
            Reporter: Xiangrui Meng
            Assignee: Xiangrui Meng


AddIntercept in Ridge and Lasso was disabled in 0.9.1 for a quick fix. For 1.0, 
we should remove this restriction.

Penalizing the intercept variable may not be the right thing to do. We can 
solve this problem by adding weighted regularization later.
