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

Three cases involved employers faxing notices to business partners notifying them of the resignations of employees, with the ex - employees id card numbers in the notices. in four other cases, companies sent letters to customers with the customers id card numbers printed on the envelopes or visible through the windows of the envelopes. in one case, an employer unnecessarily disclosed employees id card numbers in correspondence with a sub - contractor. in another case, an educational institution openly displayed the id card numbers of course attendees in an attendance book

It was suggested that eric - pcr could substitute for rapd in research related to the genetic identification and genetic diversity in auricularia and other edible and medicinal fungi : 2 to a certain extent, genetic differences among auricularia strains tested in this study did not have necessary relativity with their geographical origins respectively ; 3 in this study, genetic diversity in a. polytricha was higher than that in a. auricula : 4 in this study, a. fuscosuccinea had a higher homology to a. auricula than to a. polytricha ; 5 morphological characteristics validated the results from eric - pcr and provided a potential explanation for the higher similarity coefficient between a. auricular and a. fuscosuccinea ; 6 southern hybridization was employed by choosing a strain from a. auricula as a probe which hybridized with a. auricula and a. fuscosuccinea except a. polytricha, further confirming the veracity of the results from eric - pcr ; 7 in this study, isozyme analysis could not cluster the 7 strains from three auricularia species to different groups efficiently ; 8 2 strains from two auricularia species revealed high conservative degree and the restriction fragment patterns by 4 kinds of restricted enzymes showed no diversity
