In pattern recognition, K-mean algorithm is mainly used for clustering with known classification number, the realization is simple, the algorithm is clear, and belongs to one of the simpler dynamic clustering algorithms.In the algorithm, the convergence of the clustering centers of the two-times algorithm is determined by iteration, and then the iteration is decided whether to continue the iterative (the algorithm is exited and the classification is completed).A simple example of the following K
