Sean Owen updated SPARK-14516:
------------------------------
Priority: Minor (was: Major)
I personally think silhouette could be worth adding. The supervised metrics
require a label and not sure that's generally available in clustering problems.
> What about adding general clustering metrics?
> ---------------------------------------------

> Key: SPARK-14516
> URL: https://issues.apache.org/jira/browse/SPARK-14516
> Project: Spark
> Issue Type: Brainstorming
> Components: ML, MLlib
> Reporter: zhengruifeng
> Priority: Minor
>
> ML/MLLIB dont have any general purposed clustering metrics with a ground
> truth.
> In
> [Scikit-Learn](http://scikit-learn.org/stable/modules/classes.html#clustering-metrics),
> there are several kinds of metrics for this.
> It may be meaningful to add some clustering metrics into ML/MLLIB.
