统计学习方法读书笔记 Ch7 支持向量机（Support Vector Machine）

Statistical learning method study notes Ch7. Support Vector Machine

SVM 模型 SVM 是一种二分类模型。假设训练集中的样本是线性可分的， SVM 的目的是找到一个分类超平面，使得间隔最大化。满足间隔最大化的解是唯一的。根据模型的复杂程度，SVM可分为线性可分支持向量机、线性支持向量机和非线性支持向量机。函数间隔和几何间隔对数据进行预测，该点离分类超平面越远说明本次预测的置信度越高，反之说明置信度低。在分类超平面确定时，可以通过 $ | \o...
