C均值算法的基本思想即是通过迭代寻找c个聚类的一种划分方案，使得用这c个聚类的均值来代表相应各类样本时所得到的总体误差最小-The basic idea of ​ ​ C-means algorithm that is looking for a classification scheme through an iterative c clusters, making the overall error when using the average of these c clusters to represent all types of samples obtained corresponding minimum
