An Introduction to Support Vector Machines (SVM): Sequential Minimal Optimization (SMO)
支持向量机(SVM)概述：SMO算法求解对偶问题
Recall the Kernel SVM dual problem:
Dual Problem
$$
\max_{\lambda, \mu} L(\lambda)= \sum_{i=1}^{n}\lambda_i - \frac{1}{2}\sum_{i,j}\lambda_i \lambda_j y_i y_j K_{i,j} \\
\begin{align}
s.t.\ ...
