Improvement of Apriori algorithm

CHAI Hua-xin,WANG Yong NIC of Guilin University of Electronic Technology,Guilin,Guangxi 541004,China  
In this study,it proposes a new optimization algorithm called Napriori based on the insufficient of Apriori.Napriori algorithm presents optimizations on 2-items generation,transactions compression,items compression and join optimization.Napriori uses hash structure to generate 1-items and 2-items while compression and join optimization to generate k-items(k3).The performance study shows that Napriori is much faster than Apriori.
