摘要
讨论了形如ψ(x,Gnk(x|y))的样本函数极值特性,其中Gnk(x|y)是G(x|y)第k个最近邻域(k-NN) 的估计,得出在常规条件下存在某一Gaussian过程,使得收敛于这一Gaussian过程。
The characteristics of the extrema of some sample functions are investigated. The sample functions are in the form of ψ( x, Gnk(x | y) , where Gnk(x | y) is an estimation of G( x | y) in its k nearest neighborhood ( k-NN) . The conclusion is that under regular conditions, there exists a certain Gaussian process to which converges.
