[jira] [Created] (SPARK-9904) User guide for ML tree algorithms

Feynman Liang created SPARK-9904:
------------------------------------

             Summary: User guide for ML tree algorithms
                 Key: SPARK-9904
                 URL: https://issues.apache.org/jira/browse/SPARK-9904
             Project: Spark
          Issue Type: Documentation
          Components: ML
            Reporter: Feynman Liang


The ML Pipeline implementation of trees has diverged sufficiently from MLlib to warrant it's own user guide. Notable features which only exist in ML include:

 * Class probabilities (SPARK-6884, SPARK-6885)
 * Random Forest Feature importance (SPARK-5133)
 * Classification thresholds (SPARK-8069)
 * Checkpointing (SPARK-6684)

We should add a new section to {{ml-guide#algorithm-guides}} to describe trees in ML pipeline
