Abstract：In FCCM and its improved algorithms,Tuis assigned based on experiences or the trial and error approach. the effect of fuzzy control parameter Tuinvestigates on the clustering results of FCCM algorithm,constraining the degree of fuzzy clustering,a parameter optimization method based on partition entropy. Data experiments show that the parameter automatically determined by the proposed method can improve the clustering quality of FCCM algorithm effectively.
