[jira] [Commented] (SPARK-3219) K-Means clusterer should support
Bregman distance functions
[ https://issues.apache.org/jira/browse/SPARK-3219?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14482297#comment-14482297 ]
Sai Nishanth Parepally commented on SPARK-3219:
-----------------------------------------------
[~mengxr], is https://github.com/derrickburns/generalized-kmeans-clustering going to be merged into mllib as I would like to use "jaccard distance" as a distance metric for kmeans clustering?

> The K-Means clusterer supports the Euclidean distance metric. However, it is rather straightforward to support Bregman (http://machinelearning.wustl.edu/mlpapers/paper_files/BanerjeeMDG05.pdf) distance functions which would increase the utility of the clusterer tremendously.
> I have modified the clusterer to support pluggable distance functions. However, I notice that there are hundreds of outstanding pull requests. If someone is willing to work with me to sponsor the work through the process, I will create a pull request. Otherwise, I will just keep my own fork.
