Subject [jira] [Commented] (FLINK-1731) Add kMeans clustering algorithm to machine learning library
Date Wed, 20 May 2015 10:39:00 GMT

    [ https://issues.apache.org/jira/browse/FLINK-1731?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14552113#comment-14552113

Alexander Alexandrov commented on FLINK-1731:

[~till.rohrmann] Can we merge this with the current set of features and then add the automatic
picking of the initial centroids in another issue?

> The Flink repository already contains a kMeans implementation but it is not yet ported
to the machine learning library. I assume that only the used data types have to be adapted
and then it can be more or less directly moved to flink-ml.
> The kMeans++ [1] and the kMeans|| [2] algorithm constitute a better implementation because
the improve the initial seeding phase to achieve near optimal clustering. It might be worthwhile
to implement kMeans||.
