Theme Copy size (A_train) Possibility 2 Your variable 'A_train' has too many rows that contain at least one NaN value. kmeans () ignores any rows that contain at least one NaN value. WebKMeans算法的基本思想是初始随机给定K个簇中心,按照最邻近原则把待分类样本点分到各个簇。 然后按平均法重新计算各个簇的质心,从而确定新的簇心。 一直迭代,直到簇心的移动距离小于某个给定的值。 hold on plot (X (Idx==3,1),X (Idx==3,2),'g.','MarkerSize',14) %绘出聚类中心点,kx表示是圆形 plot (Ctrs (:,1),Ctrs (:,2),'kx','MarkerSize',14,'LineWidth',4) plot …
