Hi everyone,
@yanboliang, thanks for optimizing Kmeans.
I have a question. Is it possible to add Within Cluster Sum Square (in
total and for individual cluster) + Between cluster sum square. Since kmeans
has been exposed in SparkR and R supports those, it would be good if we could
expose those too.
We can also work on it in another jira/PR. I just want to know your opinion
on that.
Thanks,
Narine
