中文说明：这份代码实现了用支持向量机过滤垃圾邮件。采用matlab实现。是coursera上Ng给的一个练习题。该SVM使用梯度下降法实现。还给出了一个小的数据集用于实验。非常适合SVM的初学者使用。
English Description：
shiyaiFilter Spams with Support Vector Machines. it is a exercise from coursera, which is set up by Ng. A support vector machine is built up using gradient descent algorithm. And a small data set is given for your experiment.The code is very suitable for those who want to learn support vector machine! It is detailed and clear!
