在本文中,我们给出了一个简短的说明,表明收敛速度的光滑函数的多级高斯卷积的多级周期逼近。我们将在最精细的卷积中使用高斯缩放作为模型中自由度$d$的代理。我们将证明,对于高斯本征空间中的函数,收敛的阶为$d^{-\frac{\ln(d)}{\ln(2)}}$。本文为离散卷积中应该预期的内容提供了一个基线,这将是后续论文的主题。
In this paper we give a short note showing convergence rates for multilevel periodic approximation of smooth functions by multilevel Gaussian convolution. We will use the Gaussian scaling in the convolution at the finest level as a proxy for degrees of freedom $d$ in the model. We will show that, for functions in the native space of the Gaussian, convergence is of the order $d^{-\frac{\ln(d)}{\ln(2)}}$. This paper provides a baseline for what should be expected in discrete convolution, which will be the subject of a follow up paper.
