Abstract

An association rule generation algorithm usually generatestoo many rules including a lot of uninteresting ones.Many interestingness criteria are proposed to prune thoseuninteresting rules. However, they work in post-pruningprocess and hence do not improve the rule generation ef拢ciency. In this paper, we discuss properties of informativerule set and conclude that the informative rule set includesall interesting rules measured by many commonly used interestingnesscriteria, and that rules excluded by the informativerule set are forwardly prunable, i.e. they can be removedin the rule generation process instead of post pruning.Based on these properties, we propose a Direct Interestingrule Generation algorithm, DIG, to directly generateinteresting rules de拢ned by any of 12 interestingness criteriadiscussed in this paper. We further show experimentallythat DIG is faster and uses less memory than Apriori.
