---------------------------------------------------------------
Hi [~chiwanpark],
the thing is, to fit the model, the KMeans uses two datasets. One is the
training data, the other are the initial centroids. This means, the
{{fit}}-method should take two attributes at that point. This is the reason why
I suggested to use the parameter map for passing the initial centroids. The
training dataset will be passed as argument to the {{fit}}-method, equally to
the CoCoA implementation.

> Add kMeans clustering algorithm to machine learning library

> Key: FLINK-1731
> URL: https://issues.apache.org/jira/browse/FLINK-1731
> Project: Flink
> Issue Type: New Feature
> Components: Machine Learning Library
> Reporter: Till Rohrmann
> Assignee: Alexander Alexandrov
> Labels: ML
>
> 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||.
