基于矩阵的频繁项集发现算法
Frequent Itemset Obtained Algorithm Based on Matrix
【摘要】 Apriori算法是关联规则的经典算法.在分析经典Apriori算法的基础上,提出了一种有效的基于矩阵的Apriori的改进算法.该算法应用了矩阵的思想,只需对数据库扫描一次,即可得到频繁项集,大大提高了算法的效率.
【Abstract】 Apriori algorithm is the classical algorithm in association rule mining. On the basis of the research of Apriori algorithm,presentsan improved matrix-based Apriori algorithm to improve the performance of association rulealgorithm. Thisalgorithm usesthe thoughts of matrix, just needs scan the database only one time to get the frequent itemset, it increase the efficiency of algorithm.
