The Improving and Realizing of Association Rule Mining Apriori Algorithm
Xu Tang · Microcomputer Development · 2005
The Apriori algorithm is a classical algorithm of association rules mining.Reducing the number of candidate item sets is key to improve the efficiency of association rules mining.Studying the basic idea of Apriori algorithm,the algorithm by using Hash table technic is presented.The number of candidate item sets can be reduced by deleting Hash table of item in order to improve the efficiency of the Apriori algorithm.The results of experiment show that the improved algorithm is more efficient for association rules mining.
