FCM clustering divides a set of objects into a given number of clusters. Bezdek Robert Ehrlich and William Full. Most of the functionality is actually located in subpackages but like numpy we bring most of the core functionality into the base namespace. Again these are functional at the moment but the API will change to something more akin to Scikit Learn in the near future. by A and B respectively A high A T B fairly high B H A fuzzy C means quantization based automatic extraction of rotator cuff tendon tears from ultrasound images Journal of Intelligent amp Fuzzy Systems 35 2018 149 158.
