Abstract Aiming at the shortage of traditional clustering algorithm when dealing data with some nonsphericalshape distribution, a novel clustering algorithm based on the trace of sample covariance matrix is presented in this paper. This algorithm is made up of the three main parts-uniform for data, constitution of initial patterns and fusion of initial patterns. The simulation results show that compared with the traditional FCA, the proposed algorithm has good clustering performance for data with some nonsphericalshape distribution without the number of clustering.
