Summary: Validate GradientBoostedTrees during training
Key: SPARK-5436
URL: https://issues.apache.org/jira/browse/SPARK-5436
Project: Spark
Issue Type: Improvement
Components: MLlib
Affects Versions: 1.3.0
Reporter: Joseph K. Bradley
For Gradient Boosting, it would be valuable to compute test error on a separate
validation set during training. That way, training could stop early based on
the test error (or some other metric specified by the user).
