Improved apriori mining frequent items algorithm

Association rule mining is an important data mining areas of research contents,frequent itemset mining association rules mining is one of the key issues.According to the existing frequent itemset mining algorithm,based on the existing problems,this paper put forward the Apriori algorithm analysis system for Apriori-frequent itemset mining algorithm.The algorithm used overlap strategy to reduce scanning databases,thereby algorithm achieved higher efficiency.Experimental results show that the efficiency of algorithm is 1~4 times than Apriori system.
