----------------------------------------
Summary: Add random seed to GradientBoostedTrees
Key: SPARK-4607
URL: https://issues.apache.org/jira/browse/SPARK-4607
Project: Spark
Issue Type: Improvement
Components: MLlib
Affects Versions: 1.2.0
Reporter: Joseph K. Bradley
Priority: Minor
Gradient Boosted Trees does not take a random seed, but it uses randomness if
the subsampling rate is < 1. It should take a random seed parameter.
This update will also help to make unit tests more stable by allowing
determinism (using a small set of fixed random seeds).
