Analysis of circulant embedding methods for sampling stationary random fields

PieterjanRobbe/GaussianRandomFields.jl 2 Oct 2017

We examine in detail the case of the Mat\'ern covariance, and prove (for fixed correlation length) that, as $h_0\rightarrow 0$, positive definiteness is guaranteed when the random field is sampled on a cube of size order $(1 + \nu^{1/2} \log h_0^{-1})$ times larger than the size of the physical domain.

Global Optimization via Schr{ö}dinger-F{ö}llmer Diffusion

juliusberner/sde_sampler 31 Oct 2021

We study the problem of finding global minimizers of $V(x):\mathbb{R}^d\rightarrow\mathbb{R}$ approximately via sampling from a probability distribution $\mu_{\sigma}$ with density $p_{\sigma}(x)=\dfrac{\exp(-V(x)/\sigma)}{\int_{\mathbb R^d} \exp(-V(y)/\sigma) dy }$ with respect to the Lebesgue measure for $\sigma \in (0, 1]$ small enough.
