A New Kind of Emerging Pattern of Change Mining and Its Mining Algorithm

According to the fact that users are interested in the changes of multiple interest measures of association rules, a new kind of emerging pattern is presented which considers not only the changes of support but also the changes of confidence and other measures. Based on the Pareto sorting, a corresponding mining algorithm for Emerging Pattern is designed. Empirical evaluation shows that the proposed algorithm is very effective to recognize emerging patterns from two-period datasets.
