%X PCM algorithm often tends to find the identical cluster. Proposed PFCM, which divides the data set into different clusters through producing memberships and possibilities simultaneously, along with the cluster centers. But when two highly imbalanced samples clusters are given, PFCM fails to give the desired results. In order to overcome the weakness, this paper firstly mapped the original data space to a high-dimensional feature space by Mercer kernel functions, and assigned an addtional weighting factor to each vector in the feature space. Then introduced a modified objective function for fuzzy clustering in the feature space. Theoretical analysis and experimented results testify that the new algorithm has more robust and higher clustering accuracy compared with those classic fuzzy clustering algorithm.
