Speaker: Professor Philippe Fournier-Viger 

Abstract:

A popular data mining task is high utility itemset mining. It consists of discovering sets of items (products) purchased together that yield a high profit in customer transaction databases. Although many algorithms have been published for identifying high utility itemsets in transactions, many of those algorithms have important limitations such as not considering the time dimension, and finding itemsets containing items that are weakly correlated.

In this talk, Professor Fournier-Viger will discuss extensions of the high utility itemset mining problems that are designed to discover more meaningful patterns. He will first present the problem of periodic high utility pattern mining, which aims to discover recurring customer behaviour that yields a high profit (e.g. a customer buys some products every week). He will also present an algorithm to discover correlated high utility itemsets (items that yield a high profit and are strongly correlated). Finally, he will briefly mention the problem of considering the shelf time of products to discover itemsets that are profitable during specific time periods.
