The content of this chapter is indeed a bit difficult for a novice. It was so difficult for me that I couldn't take notes in my own language.
Fortunately, great masters can be found everywhere on the Internet. I found an article from "Code Farm", although what he compiled was not the Xigua book, but Chapter 7 of "Statistical Methods", Support Vector Machines. But I think it is easier to understand than the Xigua book. Chew it several times and you will always have unexpected gains!
Here is the link for everyone to learn together!
