Summary: Add instance weight support for GBTs
Key: SPARK-9612
URL: https://issues.apache.org/jira/browse/SPARK-9612
Project: Spark
Issue Type: New Feature
Components: ML
Reporter: Joseph K. Bradley
Priority: Minor
GBT support for instance weights could be handled by:
* sampling data before passing it to trees
* passing weights to trees (requiring weight support for trees first, but
probably better in the end)
