The classical problem of association pattern mining is defined in the context of supermarket data containing sets of items bought by customers, which are referred to as transactions. The goal is to determine associations between groups of items bought by customers, which can intuitively be viewed as k-way correlations between items. The most popular model for association pattern mining uses the frequencies of sets of items as the quantification of the level of association.
