             Summary: Add generic bagging algorithm to spark.ml
                 Key: SPARK-7128
                 URL: https://issues.apache.org/jira/browse/SPARK-7128
             Project: Spark
          Issue Type: New Feature
          Components: ML
            Reporter: Joseph K. Bradley


The Pipelines API will make it easier to create a generic Bagging algorithm 
which can work with any Classifier or Regressor.  Creating this feature will 
require researching the possible variants and extensions of bagging which we 
may want to support now and/or in the future, and planning an API which will be 
properly extensible.

Note: This may interact some with the existing tree ensemble methods, but it 
should be largely separate since the tree ensemble APIs and implementations are 
specialized for trees.
