Abstract:Subgroup discovery (SD) enables one to elicit patterns that strongly discriminate a class label. When it comes to numerical data, most of the existing SD approaches perform data discretizations and thus suffer from information loss. A few algorithms avoid such a loss by considering the search space of every interval pattern built on the dataset numerical values and provide an "anytime" property: at any moment, they are able to provide a result that improves over time. Given a sufficient time/memory budget, the… Show more
