Hello everybody,
I have a proposal for a very efficient Silhouette implementation in a
distributed environment. Here you can find the link with all the details of the
solution. As soon as I will finish all the implementation and the tests I will
post the PR for this:
-[https://drive.google.com/file/d/0B0Hyo%5f%5fbG%5f3fdkNvSVNYX2E3ZU0/view|https://drive.google.com/file/d/0B0Hyo__bG_3fdkNvSVNYX2E3ZU0/view].-
(please refer to https://arxiv.org/abs/2303.14102).
Please tell me if you have any comment, doubt on it.
Thanks.

> Clustering evaluator
> --------------------
>
> Key: SPARK-14516
> URL: https://issues.apache.org/jira/browse/SPARK-14516
> Project: Spark
> Issue Type: New Feature
> Components: ML
> Affects Versions: 2.2.0
> Reporter: Ruifeng Zheng
> Assignee: Marco Gaido
> Priority: Major
> Fix For: 2.3.0
>
>
> MLlib does not 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 MLlib.
> This should be added as a {{ClusteringEvaluator}} class of extending
> {{Evaluator}} in spark.ml.
