针对K-means算法随机选取中心点而无法得到全局最优误差平方和SSE的问题
提出了一种基于移动网格技术的K-means中心点选取算法
该算法在明显减少K-means算法的迭代次数的同时
近似得到SSE的全局最优.
In order to solve the problem that K-means Algorithm cannot get global optimal SSE(sum of the squared error) by choosing centers randomly
this paper presents a new algorithm of choosing centers of K-means based on shifting grid
which decreases iterative time of K-means obviously and gets the global optimal of SSE approximately.
