Improvement of Apriori Algorithm for Mining Association Rules

This paper puts forward an enhanced algorithm which associates Apriori with hash technique and transaction reduction technique. The construction and the influence to algorithm's efficiency of hash function is studied.The theory and realizable method of transaction reduction technique are also analyzed.And then the realizable steps of the foold algorithm and the enhanced algorithm are made out through an example. The result shows that the new algorithm promotes the algorithm' efficiency and at the same time improves the performance of the data mining technique through cutting down the store space.
