In data mining, there are several works proposed for mining the association rules which are frequent. Researchers argue that mining the infrequent item sets are also important in certain applications. Discovering association rules are based on the preset minimum support threshold given by domain experts. The accuracy in setting up this threshold directly influences the number and the quality of association rules discovered. Even though the number of association rules is large, some interesting rules will be missing and the rules quality requires further analysis.
