Abstract:

An improved incremental updating algorithm SFUP was proposed based on study of the principle and efficiency of FUP algorithm. The algorithm made full use of the old data mining results and reduces the times of scanning the database greatly, thus the data mining efficiency increases. Some experiments show that SFUP is better than FUP at many aspects.
