问题如下：
which of the following statements is incorrect?
选项：
A.
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.
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：
不太理解c选项的意思
NO.PZ2019100902000019 1.AR值(AccuraRatio)在原版书多少页有，没找着。 2.公式里的AP是什么意思，AR又是什么意思。 3.然后还有就是。。感觉原版书和课件几乎完全对不上，像这个线性判别+K临近，还有很多定性定量跟原版书的定性定量说的也不一样，Z-score我也没找到，这个是原版书的问题吗，还是什么问题 辛苦老师解答~
K-nearest neighbor approauses Non-parametric classification in the Support vector machines, the main ia is to separate the various classes of ta (observations) using the best separating hyperplane (BSH), for whithe stanto two parallel hyperplanes on easi is the largest. In the Fisher Linescriminant analysis, the principaim is to segregate anclassify a heterogeneous population in heterogeneous subsets. 答案is correct. 解析本题让错误的一个描述，A/B/C三个描述均正确。误，正确描述为 the principaim is to segregate anclassify a heterogeneous population in homogeneous subsets. 老师，什么意思？以及答案的翻译。

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！
