Abstract :
Through the study of Apriori algorithm we discover two aspects that affect the efficiency of the algorithm. One is the frequent scanning database, the other is large scale of the candidate itemsets. Therefore, IApriori algorithm is proposed that can reduce the times of scanning database, optimize the join procedure of frequent itemsets generated in order to reduce the size of the candidate itemsets. The results show that the algorithm is better than Apriori algorithm.
