称 K:\mathbb{R}^{d}\times\mathbb{R}^{d}\rightarrow\mathbb{R},\ K(x,z)=\langle\phi(x),\phi(z)\rangle为核函数(kernel function)。 这样的算法称为Kernel method for regession,最终的算法为: Kernel method for regession 考虑维度 i, j 后,计算所有的 kernel 的总时间复杂度为 O(n^...

此时kernel Methods可以巧妙地绕开feature map ϕ(x) 的计算,从另一条路径简单高效的得到上述内积的计算结果。因此需要定义kernel function K(x,z):=<ϕ(x),ϕ(z)> 来实现上述目标,下面将讨论几种常见的kernel function。 常用Kernel function Polynomial kernel 定义K(x,z)=(xTz+c)k ,设特征 x 的...

nite kernels have become rather popular, particularly in machine learning. Since these methods have a stronger mathematical slant than earlier machine learning methods (e.g., neural networks), there is also signi?cant interest in the statistics and mathematics community for these methods. The ...
