机器学习主要任务
如何选择合适的算法?
目的
如果想要预测目标变量的值,则可以选择监督学习算法,否则可以选择无监督学习算法。确定监督学习算法之后需要需要进一步确定目标变量类型,如 果目标变量是离散型,则可以选择分类器算法;如果目标变量是连续型的数,则需要选择回归算法。
如果不想预测目标变量的值,则可以选择无监督学习算法。进一步分析是否需要将

隐含形式
法线形式: [\vec{n}\cdot X = d] 直线法线所在的平面叫做直线的正面,其代数表示为(\vec{n}\cdot X -d>0)。另一个平面叫做直线的负面,(\vec{n}\cdot X - d<0)
另一种常见的隐含形式 [ax+by+c=0]
参数形式
直线的参数形式为(X(t)=P+t\vec{d},t

第1章 介绍
数值计算的问题
浮点数计算的困境
底层问题
当浮点数相加时,大的会覆盖小的。 在浮点数运算中,如果f(r)比f(s)和f(t)大得多,那么就有 [f(r)+f(s) = f(r),f(r)+f(t) = f(r)\Rightarrow (f(r)+f(s))+f(t)=f(r)] 但有可能f(s)+f(t)足够大导致: [f(r)+(f(s)+f(t))\ne f(r)
