             Summary: Add cosine distance measure to ClusteringEvaluator
                 Key: SPARK-23217
                 URL: https://issues.apache.org/jira/browse/SPARK-23217
             Project: Spark
          Issue Type: Improvement
          Components: ML
    Affects Versions: 2.3.0
            Reporter: Marco Gaido
         Attachments: SPARK-23217.pages

SPARK-22119 introduced the cosine distance measure for KMeans. Therefore it would be useful to provide also an implementation of ClusteringEvaluator using the cosine distance measure.

 

Attached you can find a design document for it.
