Alex updated SPARK-2344:
------------------------
Description:
I would like to add a FCM (Fuzzy C-Means) algorithm to MLlib.
FCM is very similar to K - Means which is already implemented, and they differ
only in the degree of relationship each point has with each cluster:
(in FCM the relationship is in a range of [0..1] whether in K - Means its 0/1.
As part of the implementation I would like:
- create a base class for K- Means and FCM
- implement the relationship for each algorithm differently (in its class)
I'd like this to be assigned to me.
