Pragmatism of pattern mining system is to study the data and determines a model that is closets to characteristics of the data being examine. This necessitates identifying interesting association patterns idea can be described as a recursive eradication method in a preprocessing step, that remove all items from the transactions that are not regular individually, i.e., do not appear in a user-specified least number of transactions. Then choose all transactions that have the least regular item (least frequent along with those that are frequent) and delete this item from them. Recursive to procedure the obtained reduced (also known as projected) database, evoke that the entry sets construct in the recursion split the deleted item as a prefix.
