Thanks for your contribution @HilmiYildirim. I had some comments.
I'm not so sure about the correctness of the implementation. Where did you
get the testing data from @HilmiYildirim. Is that from some published source?
The current implementation lacks the integration with the FlinkML's
pipelining mechanism. Furthermore, it only works on `integers`. What if the
observations are characters for example.
The PR needs more documentation for better understanding the code and
maintaining it.
Could we maybe add a smaller test file. One of the files is 2MB large. This
should definitely be smaller.
I think this PR needs a little bit of more effort to get in shape.
