首先,将事务数据集转换为布尔矩阵表示,然后调用fpgrowth函数来寻找指定最小支持度阈值的频繁项集。 另外,如果你想使用自己实现的FP-Growth算法,可以参考相关的开源实现和算法细节。以下是一些学习资源,可以帮助你更深入地了解FP-Growth算法: Han, J., Pei, J., & Yin, Y. (2000). Mining frequent patterns wit...
We tend to propose an improved technique that extracting association rules from web data knowledge without any preprocessing or post processing. We propose improved algorithm, for mining the entire set of frequent patterns by pattern fragment growth. First Frequent Pattern-tree based mining adopts a ...
1.1 FP-growth算法简介 FP-growth算法是Han Jiawei等人于2000年提出的发现频繁项集的算法,该算法采用分治策略将一个问题分解为较小的子问题,从而发现以某个特定后缀结尾的所有频繁项集。该算法使用了一种称之为频繁模式树FP-tree(Frequent Pattern Tree)的数据结构,FP-tree是一种特殊的前缀树,由频繁项头表和项前...
