> Key: SPARK-13226
> URL: https://issues.apache.org/jira/browse/SPARK-13226
> Project: Spark
> Issue Type: Improvement
> Components: MLlib
> Reporter: holdenk
> Priority: Trivial
>
> The current MLLib PowerIteration clustering implementation sets the number of runs inside of the kmeans call to 5 (apparently arbitrary). This should likely be replaced with a specific tolerance.
> The reference implementation also appears to use a tolerance, so this would also be moving closer to the reference implementation ( http://www.cs.cmu.edu/~wcohen/ )
