[jira] [Commented] (SPARK-11664) Add methods to get bisecting k-means cluster structure

    [ https://issues.apache.org/jira/browse/SPARK-11664?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15604340#comment-15604340 ]

----------------------------------

Hi, I was wondering what's the progress on this? [~yuu.ishikawa@gmail.com] had somehow already implemented this feature [https://github.com/yu-iskw/bisecting-kmeans] before this issue was raised. Why wasn't the dendrogram feature included in the current build? Thanks

> I think users want to visualize the result of bisecting k-means clustering as a dendrogram in order to confirm it. So it would be great to support method to get the cluster tree structure as an adjacency list, linkage matrix and so on.
