Apache Spark reassigned SPARK-22119:
------------------------------------
Assignee: (was: Apache Spark)
> Add cosine distance to KMeans
> -----------------------------
>
> Key: SPARK-22119
> URL: https://issues.apache.org/jira/browse/SPARK-22119
> Project: Spark
> Issue Type: New Feature
> Components: ML, MLlib
> Affects Versions: 2.2.0
> Reporter: Marco Gaido
> Priority: Minor
>
> Currently, KMeans assumes the only possible distance measure to be used is
> the Euclidean.
> In some use cases, eg. text mining, other distance measures like the cosine
> distance are widely used. Thus, for such use cases, it would be good to
> support multiple distance measures.
> This ticket is to support the cosine distance measure on KMeans. Later, other
> algorithms can be extended to support several distance measures and other
> distance measures can be added.
