Description: K-MEANS算法
输入:聚类个数k,以及包含 n个数据对象的数据库。
输出:满足方差最小标准的k个聚类。
处理流程:
(1) 从 n个数据对象任意选择 k 个对象作为初始聚类中心;
(2) 循环(3)到(4)直到每个聚类不再发生变化为止
(3) 根据每个聚类对象的均值(中心对象),计算每个对象与这些中心对象的距离;并根据最小距离重新对相应对象进行划分;
(4) 重新计算每个(有变化)聚类的均值(中心对象)-K-MEANS algorithm Input: cluster number k, and contains n data object database. Output: the minimum standards to meet the variance k-clustering. Deal flow: (1) a data object from the n choose k object as initial cluster centers (2) cycle (3) to (4) until a change in each cluster is no longer so far (3) according to each Clustering objects mean (central object), calculated for each object with these centers to object distance and in accordance with a minimum distance between a re-division of the corresponding object (4) re-calculated for each (change) clustering of the mean (central object ) Platform: |

Description: 用VC或Java实现K-means聚类算法,分别以迭代次数及分配不再发生变化为算法终止条件,用图片(自己选择)作为数据集,比较运行时间(画出时间与像素点的关系曲线图,因此须用多幅像素个数不同的图片进行实验),提交实验报告与源代码。-K-means clustering algorithm for algorithm termination conditions, with a picture (their choice) as a data set to compare the running time (draw time and the relationship of the pixels, respectively, the number of iterations and distribution no longer changes with VC or Java experimental curve, so to use pictures of different pieces of the number of pixels), submitted to the lab report with source code.
