Summary: Add setBins for BinaryClassificationMetrics in
mlllb/evaluation
Key: SPARK-17505
URL: https://issues.apache.org/jira/browse/SPARK-17505
Project: Spark
Issue Type: Improvement
Components: MLlib
Reporter: Peng Meng
Priority: Minor
Add a setBins method for BinaryClassificationMetrics.
BinaryClassificationMetrics is a class in mllib/Evaluation. numBins is a key
attribute of it. If numBins greater than 0, then the curves (ROC curve, PR
curve) computed internally will be down-sampled to this many "bins".
It is useful to let the user set the numBins.
