AI总结:

本文针对粗糙函数,利用径向基函数的散乱平移进行插值,建立了当插值点填充有界域时的误差估计。

摘要:

当插值点填充R^d中的有界域时,适当光滑函数与其径向基函数插值之间的误差是一个研究充分的问题。在所有情况下,分析都在由径向基函数选择所决定的自然函数空间——原生空间中进行。原生空间包含具有一定光滑度的函数。本文建立了当被插值函数明显粗糙时的误差估计。

英文摘要:

The error between appropriately smooth functions and their radial basis function interpolants, as the interpolation points fill out a bounded domain in R^d, is a well studied artifact. In all of these cases, the analysis takes place in a natural function space dictated by the choice of radial basis function -- the native space. The native space contains functions possessing a certain amount of smoothness. This paper establishes error estimates when the function being interpolated is conspicuously rough.
