基于兴趣度剪枝的Apriori优化算法
Optimized Apriori algorithm based on interestingness measure pruning
-
摘要: 鉴于关联规则挖掘中的Apriori算法在挖掘潜在有价值、低支持度模式时效率较低,因此提出一种优化的Apriori挖掘算法,即在频繁项集挖掘中引入项项正相关兴趣度量剪枝策略,有效过滤掉非正相关长模式和无效项集,从而扩大了可挖掘支持度阈值范围.实验结果表明,该算法是有效和可行的.Abstract: To solve the problem that the Apriori algorithm of mining association rules in database mining is not quite effective in the process of mining potentially valuable low-support patterns,an optimized apriori mining algorithm was proposed.This algorithm exploits an efficient pruning strategy which uses the interestingness measure to filter the non-positive correlated long model and invalid itemsets.The range of support threshold is expanded.The experimental results indicated that the given algorithm was efficient and feasible.
