【Abstract】 A novel algorithm, QAR, for mining quantitative association rules and an incremental updating algorithm, IUQAR, are proposed. Based on fuzzy set theory, a set of fuzzy concepts, which are defined in quantitative attribute domains, are employed to represent the revealed regularities among quantitative attributes and the drowbacks caused by the traditional discrete interval method are overcome. Besides, the algorithm, IUQAR, effectively solves maintenance problem of the regularities.更多还原
