Along with multiple cores, the core processor to become the mainstream of computing devices, pattern recognition, realization of parallel system in the future will need corresponding parallel algorithm research as its theoretical basis. In order to solve this problem, in this paper, the nuclear class separability between the fuzzy c-means algorithm optimization are analyzed, through the fuzzy c-means algorithm for data set C, C- average clustering algorithm and fuzzy C- average clustering algorithm in detail, which leads to the nuclear fuzzy C-average clustering algorithm, this method is increased by the optimization of sample characteristics, application samples of kernel function of the input space is mapped to high-dimensional feature space, and clustering in the feature space, the kernel function clustering method in performance than classical clustering algorithm has great improvement, it through nonlinear mapping can distinguish useful feature, extracted and amplified, achieve a more accurate and more rapid clustering. Through the simulation experiments show that the clustering effect KFCM algorithm model can distinguish between two types of completely.
