In fuzzy c-means the centroid of a cluster is the mean of all points, weighted by their degree of belonging to the cluster.

discussed on July 6, 2015 call. Is this term still needed? If so, please identify parent. For example, would that be 'probabilistic algorithm'? http://purl.obolibrary.org/obo/OBI_0200052
Also, would fuzzy clustering objective be appropriate? http://purl.obolibrary.org/obo/OBI_0000653
