Abstract: A new hybrid clustering algorithm based on particle swarm optimization and FCM algorithm is proposed.By incorporating the robust and global search and taking the clustering result of PSO as the initialized value of the FCM,the algorithm eliminates FCM trapped local optimum and being sensitive to initial value effectively,and solves weaker local search of PSO.The algorithm is initialized by a statistical histogram based FCM algorithm,which can speed up the convergence of the algorithm.Experimental results sh...
