-----------------------------------------
Summary: GBTClassifier needs a raw prediction column
Key: SPARK-16969
URL: https://issues.apache.org/jira/browse/SPARK-16969
Project: Spark
Issue Type: Bug
Reporter: Vladimir Feinberg
When working with a skewed-label dataset I found the GBTClassifier pretty
unusable because it performs an automatic thresholding at the halfway point,
without exposing the raw prediction.
This prevents use of different thresholds and any of the
BinaryClassificationEvaluator tools.
