Summary: Implement RandomProjection for Dimensionality Reduction
Key: SPARK-7334
URL: https://issues.apache.org/jira/browse/SPARK-7334
Project: Spark
Issue Type: Improvement
Components: MLlib
Reporter: Sebastian Alfers
Priority: Minor
Implement RandomProjection (RP) for dimensionality reduction (DR)
RP is a popular approach to reduce the amount of data while preserving a
reasonable amount of information (pairwise distance) of you data [1][2]
