代码说明:

刚刚学了数据挖掘的这个算法,马上实现下,怕忘掉了。。感觉matlab的好处就是矩阵可以一起进行逻辑运算,不过我没有进行预处理,输入的数据集保存在txt文件里,且都是以0-1矩阵构成的,不考虑出现次数。输出只实现了得到k-频繁项集,没有计算最终的关联规则。。那个感觉要遍历什么的,用矩阵枚举???还没想到怎么弄。。。。    从k频繁项集得到k+1频繁项集,通过两个k频繁项向量进行或运算得到。。   剪枝判断k+1-候选项的子串是否在k频繁项集中存在,通过向量 异或 xor来判断   统计支持度   提取数据集中指定列   进行与运算    再通过 sum 求和计算 支持度。。

下载说明:请别用迅雷下载,失败请重下,重下不扣分!
