Abstract: For the inadequacy of Apriori algorithm in association rules,this paper presents two methods of Apriori Algorithm based on matrix.Improved algorithms make full use of the matrix to significantly reduce the number of scans the database and computing costs,and then improve the efficiency of the algorithm effectively.Meanwhile,the application example and algorithm performance analysis shows that the proposed two improved algorithms are efficient association rule mining method,and the properties are better than the Apriori algorithm.
