Definition 1. A Gaussian Process is a collection of random variables, any finite number of which have (consistent) joint Gaussian distributions. 高斯分布(Gaussian Distribution) 是由方差向量(一维的时候是一个常量)和一个协方差矩阵(一维是方差)确定. 而高斯过程是一个随机过程的集合,它由一个均值函数m(x)和方差函数k(x,x')…

比较难理解,通过做题来入门. 目的:简单的了解下相关概念. 基础 热身 目的:找x到y的映射关系. 假设:Q latent functions {fi} fj 作为先验,跟x没什么直接关系,x只是作为承载超参数的载体.共有Q个,也就是有Q套超参数. 对于公式(4),x --> f --> (noise) --> y,大概就是这么个关系. 因为noise,当然y是iid. 由公式(3)可见,f也是iid. 一般而言,Q等于多分类的类别数量,P = 1即可(无需one-hot). 开始 没看…
