Optimized association rules are permitted to contain uninstantiated attributes. the optimization procedure is to determine the instantiations such that some measures of the roles are maximized. this paper tries to maximize interest to find more interesting rules. on the other hand, the approach permits the optimized association rule to contain uninstantiated numeric attributes in both the antecedence and the consequence. a naive algorithm of finding such optimized rules can be got by a straightforward extension of the algorithm for only one numeric attribute. unfortunately, that results in a poor performance. a heuristic algorithm that finds the approximate optimal rules is proposed to improve the performance. the experiments with the synthetic data sets show the advantages of interest over confidence on finding interesting rules with two attributes. the experiments with real data set show the approximate linear scalability and good accuracy of the algorithm
優化關聯規則允許在規則中包含未初始化的屬性.優化過程就是確定對這些屬性進行初始化,使得某些度量最大化.最大化興趣度因子用來發現更加有趣的規則;另一方面,允許優化規則在前提和結果中各包含一個未初始化的數值屬性.對那些處理一個數值屬性的演算法進行
直接的擴展,可以得到一個發現這種優化規則的簡單演算法.然而這種方法的性能很差,因此,為了改善性能,提出一種啟發式方法,它發現的是近似最優的規則.在人造數據集上的實驗結果表明,當優化規則包含兩個數值屬性時,優化興趣度因子得到的規則比優化可
信度得到的規則更有趣.在真實數據集上的實驗結果表明,該演算法具有近似線性的可擴展性和較好的精度
