摘　　要：在数据挖掘中,分类器是一种比较重要的方法,其中Fisher分类器属于一种基础的分类器。文中将蜕变测试应用于Fisher分类器,结合既有的一些研究成果,采用对蜕变关系分类构造的方法,从几何属性、数值属性、算法特性三个方面重新构造了适用于Fisher分类器的蜕变关系,并将对分类结果的判断简化为对分类面的判断。实验结果表明,所有的变异都被检测出来,蜕变关系之间可以很好地互补,并且可以借鉴到一些分类器程序的测试过程中,使分类器蜕变关系的构造更加简便和完善。In data mining,the classifier is an important method,in which the Fisher classifier belongs to a basic classifier.In this paper,the metamorphic testing is applied to the Fisher classifier.Combining with some existing research results,method for classifying metamorphic relationsare is used to reconstruct the metamorphic relations applicable to the Fisher classifier from three aspects:geometric attributes,numerical attributes and algorithm characteristics.And the judgment of the classification result is simplified to the judgment of the classification surface.The experimental results show that all the mutations are detected,the metamorphic relations can be well complemented,and some other classifier programs can learn the test procedures.This makes the classifier's metamorphic relation easier and more complete.
