Lei Wang created SPARK-17934:
--------------------------------
Summary: Support percentile scale in ml.feature
Key: SPARK-17934
URL: https://issues.apache.org/jira/browse/SPARK-17934
Project: Spark
Issue Type: New Feature
Components: ML
Reporter: Lei Wang
Percentile scale is often used in feature scale.
In my project, I need to use this scaler.
Compared to MinMaxScaler, PercentileScaler will not produce unstable result due
to anomaly large value.
About percentile scale, refer to https://en.wikipedia.org/wiki/Percentile_rank
