所谓VC维是对函数类的一种度量，可以简单的理解为问题的复杂程度，VC维越高，一个问题就越复杂。正是因为SVM关注的是VC维，后面我们可以看到，SVM解决问题的时候-The so-called VC dimension is a measure of the function classes, it can be simply understood the complexity of the problem, VC dimension, the more complex a problem. It is because of SVM VC dimension is concerned, we can see the back, when the SVM to solve the problem
