Hi,
I have started 2 PRs to solve the problem you metioned.
About the "CentroidInitializer" I have a new idea:
Move CentroidInitializers as inner classes of "KMeansPlusPlusCluster",
and add a construct parameter and a property "useKMeansPlusPlus" to
"KMeansPlusPlusCluster":
```java

Hi all,
The "EmptyClusterStrategy" in KMeansPlusPlusClusterer can be reused
MiniBatchKMeansClusterer and other cluster altorithm.
So I think the "EmptyClusterStrategy" should move out from
KMeansPlusPlusClusterer(JIRA issue #MATH-1525).
I am not sure if my design is good or not. I thi
Hi,
I have created a JIRA issue for this suggestion:
https://issues.apache.org/jira/projects/MATH/issues/MATH-1522
I think the generic parameter on class "ClusterRanking" is unnecessary,
it is redundancy when define a variable, and hard to reuse(it could be):
```java

Hi,
For machine learning centroid cluster algorithm, we often use is
Calinsk-iHarabasz score to evaluate which algorithm or how many centers is best
for a dataset.
The python lib sklearn implements Calinsk-iHarabasz as
sklearn.metrics.calinski_harabasz_score.
I think there should be a C
