Finding of hidden and previously unknown information in large collection of data is the process of data mining. Mining association rules is a very important model in data mining. Using association rules different type of regularities and patterns can be identified. In most of the previous approaches, a single minimum support threshold value is used for all the items or item sets. But all the items in an item set do not behave in the same way. Some appear very frequently and some very rarely.
