Abstract：Association rule mining can found useful information from the data. This paper introduces the basic idea of the DHP algorithm. DHP algorithm uses the hash pruning techniques to reduce the amount of data. Illustrate the execution of DHP algorithm and analyze the performance of DHP algorithm. It generates frequent itemsets efficiently, it solves the bottleneck when generates frequent 2 - itemsets performance, and reducing transaction database size and reducing the number of database scans.
