Discovering frequent item sets is the main way of association rules mining, and it is also the focus of the study in algorithms for association rules mining. The classical Apriori algorithm and its improved algorithms of association rules mining can be generally classified as one based on SQL and the other based on memory. To improve the data-mining efficiency, the authors proposed an efficient algorithm for discovering frequent item sets. After analyzing the efficiency bottlenecks in some algorithms based on memory, the algorithm used a method that could generate and test candidate item sets efficiently to optimize the speed of item sets generation. The experimental results show that the proposed algorithm can assuredly improve the mining efficiency.
