Abstract

With large database, the process of mining association rules is time consuming. The efficiency becomes crucial factor. By analyzing Apriori algorithm and its improvement, the improved Apriori algorithm is applied to early warning of equipment failure. Moreover, Apriori algorithm is improved by reducing the number of scanning data base and the number of candidate item-set in advance which might become frequent item. Apriori algorithm and the improved Apriori algorithm are compared by the example of equipment failure. Finally, the improved Apriori algorithm is proved that it can improve the efficiency by experiment.
