According to the author: this series of blog posts only introduces libsvm binary classification, rather than studying libsvm's professional standardsArticle. As for how to use libsvm for regression and multiclass classification, I haven't covered it yet. Please refer to the libsvm documentation.

The text preprocessing module (written in Python) is provided here. The libsvm is called to write the text classification module in C language. The experimental result processing module (MatLab)
