... sense, each concept-formative cluster can be characterized by a membership function. Fuzzy clustering allows for some ambiguity in the data, and its main advantage over hard clustering is that it ... three lambdas are parameters whose purpose is balancing the three factors. To be concept-formative, a cut (i) must have a sufficiently high quality and (ii) must be locally optimal. 2....
