c选项怎么翻译啊

NO.PZ2019100902000019

问题如下:

which of the following statements is incorrect?

选项:

A.

In the cumulative accuracy profile or CAP(also called GINI curve), the accuracy ratio (AR) is defined as AR/AR+Ap, the closer this ratio is to 1, the more accurate is the model.

B.

K-nearest neighbor approach uses Non-parametric classification

C.

in the Support vector machines, the main idea is to separate the various classes of data (observations) using the best separating hyperplane (BSH), for which the distance to two parallel hyperplanes on each side is the largest.

D.

In the Fisher Linear discriminant analysis, the principal aim is to segregate and classify a heterogeneous population in heterogeneous subsets.

解释:

答案:D is correct.

解析:本题让选项错误的一个描述,A/B/C三个描述均正确。D选项错误,D选项的正确描述为:

the principal aim is to segregate and classify a heterogeneous population in homogeneous subsets.

不太理解c选项的意思

C就是在说Support vector machines这个方法是怎么分类的,老师在“Credit Scoring Models-Quantitative methodologies”这一节视频最后一部分有讲到这个方法,可以去听一下,很详细

A也是错的吧,原版书322页说Accuraratio是Ar/Ap

请问能否一下A啥意思呀?好像学到这里没有涉及?谢谢!
