In traditional pattern mining, one would find the complete set of patterns and then apply a post-pruning step to it. The size of the complete mining results is typically prohibitively large, despite the fact that only a small percentage of high utility patterns are interesting. Thus
WebHigh utility pattern mining extracts more useful and realistic knowledge from transaction databases compared to the traditional frequent pattern mining by considering the non-binary frequency values of items in transactions and different profit values for every item.
