Meshfree approximation methods are a relatively new area of research, and there are only a
few books covering it at present. Whereas other works focus almost entirely on theoretical …

[HTML][HTML] The Runge phenomenon and spatially variable shape parameters in RBF interpolation

B Fornberg, J Zuev - Computers & Mathematics with Applications, 2007 - Elsevier
Many studies, mostly empirical, have been devoted to finding an optimal shape parameter
for radial basis functions (RBF). When exploring the underlying factors that determine what …

[PDF][PDF] Multiquadric radial basis function approximation methods for the numerical solution of partial differential equations

Impossibility of fast stable approximation of analytic functions from equispaced samples

RB Platte, LN Trefethen, ABJ Kuijlaars - SIAM review, 2011 - SIAM
It is shown that no stable procedure for approximating functions from equally spaced
samples can converge exponentially for analytic functions. To avoid instability, one must …

On the positivity and magnitudes of Bayesian quadrature weights

T Karvonen, M Kanagawa, S Särkkä - Statistics and Computing, 2019 - Springer
This article reviews and studies the properties of Bayesian quadrature weights, which
strongly affect stability and robustness of the quadrature rule. Specifically, we investigate …

[PDF][PDF] Exponentially-convergent strategies for defeating the Runge phenomenon for the approximation of non-periodic functions, part I: single-interval schemes

JP Boyd, JR Ong - Comput. Phys, 2009 - researchgate.net
Approximating a function from its values f (xi) at a set of evenly spaced points xi through
(N+1)-point polynomial interpolation often fails because of divergence near the endpoints …

RBF collocation methods as pseudospectral methods

GE Fasshauer - WIT transactions on modelling and simulation, 2005 - witpress.com
We show how the collocation framework that is prevalent in the radial basis function
literature can be modified so that the methods can be interpreted in the framework of …
