矩阵约束下的频繁项集挖掘方法研究
Matrix constrained frequent itemsets mining method
摘要
Abstract
Association analysis techniques in data mining are aimed at discovering interesting association among a large number of data itemsets, and the core problem is to find frequent itemsets.In traditional association mining algorithm based on matrix,the matrix size is related to the transaction database size.Thus memory bottlenecks still exist in dealing with very large transaction databases.This paper presents a frequent itemsets discovery algorithm to solve this problem.In the pre-min-ing and post-validating matrix constrained algorithm the matrix size is independent of the transaction database size.Experimen-tal results show that this algorithm improves the speed of frequent itemsets mining.关键词
