用C#实现k均值聚类算法 C# C# PAUL-MAPLE k均值算法是模式识别的聚分类问题，这是用C#实现其算法 以下是程序源代码： using System; using System.Drawing; using System.Collections; using System.ComponentModel; using System.Windows.Forms; using System.Data; namespace KMean_win { /// /// Form1 的摘要说明。 /// public class Form1 : System.Windows.Forms.Form { /// /// 必需的设计器变量。 /// private System.ComponentModel.Container components = null; private static int k = 2; //类数，此例题为2类 private static int total = 20; //点个数 private int test = 0; private PointF[] unknown = new PointF[total]; //点数组 private int[] type = new int[total]; //每个点暂时的类 public PointF[] z = new PointF[k]; //保存新的聚类中心 public PointF[] z0 = new PointF[k]; //保存上一次的聚类中心 private PointF sum; private int temp = 0; private System.Windows.Forms.TextBox textBox1; private int l = 0; //迭代次数 //构造函数，初始化 public Form1() { unknown[0]=new Point(0,0); unknown[1]=new Point(1,0); unknown[2]=new Point(0,1); unknown[3]=new Point(1,1); unknown[4]=new Point(2,1); unknown[5]=new Point(1,2); unknown[6]=new Point(2,2); unknown[7]=new Point(3,2); unknown[8]=new Point(6,6); unknown[9]=new Point(7,6); unknown[10]=new Point(8,6); unknown[11]=new Point(6,7); unknown[12]=new Point(7,7); unknown[13]=new Point(8,7); unknown[14]=new Point(9,7); unknown[15]=new Point(7,8); unknown[16]=new Point(8,8); unknown[17]=new Point(9,8); unknown[18]=new Point(8,9); unknown[19]=new Point(9,9); InitializeComponent();
