| 摘 要： | 文中提出了一种基于遗传算法的生成隶属度函数的方法,该方法通过遗传算法对初始种群进行优化,获得一个适应度较高的隶属度函数编码,然后再根据机场噪声数据的实际标准对优化后得到的隶属度函数进行修正,进而得到梯形分布的隶属度函数编码.最后通过得到的隶属度函数对数据进行模糊化,并采用FP-trees算法生成模糊关联规则.该文针对数量型属性提出了这种方法,它的优点是能够使通过遗传算法得到的较优的隶属度函数更加适用于实际的数据集.

| Abstract: | In this paper,a GA-based approach is proposed to find out membership functions.The proposed approach optimize the initial population by GA,then membership functions is got with high suitability.Then an isosceles-trapezoid membership functions is got,according to the real standard of data of airport noise.The quantitative value of each transaction datum is transformed into a fuzzy set according the membership functions.The fuzzy association rules will be generated by FP-trees algorithm.The proposed approach focuses on the quantitative items.It can make the membership functions derived by GA be more suitable for the real data. |
