Comments on "A possibilistic approach to clustering"
Mauro Barni, Vito Cappellini, A. Mecocci · IEEE Transactions on Fuzzy Systems · 1996
In this comment, we report a difficulty with the-application of the possibilistic approach to fuzzy clustering (PCM) proposed by Keller and Krishnapuram (1993). In applying this algorithm we found that it has the undesirable tendency to produce coincidental clusters. Results illustrating this tendency are reported and a possible explanation for the PCM behavior is suggested.
