-----------------------------------------
Summary: Decide whether spark.ml Decision Tree and Random Forest
can replace spark.mllib implementation
Key: SPARK-10232
URL: https://issues.apache.org/jira/browse/SPARK-10232
Project: Spark
Issue Type: Task
Components: ML, MLlib
Reporter: Joseph K. Bradley
Assignee: Joseph K. Bradley
This JIRA is for discussing replacing the spark.mllib DecisionTree and
RandomForest implementations with the implementation in spark.ml. The new
implementation is simply a copy, with slight modifications (removing "bins").
Pros:
* Support only 1 implementation.
* Efficiency gains in spark.ml will benefit both APIs.
Cons:
* As spark.ml tree functionality increases, we will need to maintain conversion
code for converting spark.ml trees to spark.mllib trees.
Must:
* Ensure we do not have significant regressions in the new implementation.
