kMeans

代码说明：

  基于原型的目标函数聚类方法，数据点到原型的某种距离作为优化的目标函数，利用函数求极值的方法得到迭代运算的调整规则(A prototype based objective function clustering method, the data point to a certain distance from the prototype is used as the objective function of the optimization, and the adjustment rule of the iterative operation is obtained by the method of finding the extremum of the function.)
