The interpolation theory of radial basis functions

B Baxter - arXiv preprint arXiv:1006.2443, 2010 - arxiv.org
In this dissertation, it is first shown that, when the radial basis function is a $p$-norm and $1
< p < 2$, interpolation is always possible when the points are all different and there are at …

Radial basis functions for the sphere

BJC Baxter, S Hubbert - Recent Progress in Multivariate Approximation …, 2001 - Springer
In this paper we compute the ultraspherical series expansions for the more commonly used
radial basis functions. In several special cases we provide asymptotic estimates for the …

[HTML][HTML] Rapid evaluation of radial basis functions

G Roussos, BJC Baxter - Journal of Computational and Applied …, 2005 - Elsevier
Over the past decade, the radial basis function method has been shown to produce high
quality solutions to the multivariate scattered data interpolation problem. However, this method …

Invertible and non-invertible information sets in linear rational expectations models

B Baxter, L Graham, S Wright - Journal of Economic Dynamics and control, 2011 - Elsevier
Rational expectations solutions are usually derived by assuming that all state variables
relevant to forward-looking behaviour are directly observable, or that they are “…an invertible …

Conditionally positive functions andp-norm distance matrices

BJC Baxter - Constructive Approximation, 1991 - Springer
In [4], deep results were obtained concerning the invertibility of matrices arising from radial
basis function interpolation. In particular, the Euclidean distance matrix was shown to be …

[HTML][HTML] Multi-stage resistance to Zymoseptoria tritici revealed by GWAS in an Australian bread wheat diversity panel

N Yang, B Ovenden, B Baxter, MC McDonald… - Frontiers in Plant …, 2022 - frontiersin.org
Septoria tritici blotch (STB) has been ranked the third most important wheat disease in the
world, threatening a large area of wheat production. Although major genes play an important …

A new error estimate of the fast Gauss transform

BJC Baxter, G Roussos - SIAM Journal on Scientific Computing, 2002 - SIAM
The fast Gauss transform of L. Greengard and J. Strain [SIAM J. Sci. Statist. Comput., 12 (1991),
pp. 79--94] reduces the computational complexity of the evaluation of the sum of N …

Convergence estimates for stationary radial basis function interpolation and for semi-discrete collocation-schemes

B Baxter, R Brummelhuis - Journal of Fourier Analysis and Applications, 2022 - Springer
We give a Fourier-theoretic analysis of the convergence of semi-discrete Radial Basis Function
interpolation on regular grids and of the associated semi-discrete collocation schemes …

Iron Oxidation–Reduction Processes in Warming Permafrost Soils and Surface Waters Expose a Seasonally Rusting Arctic Watershed

AJ Barker, TD Sullivan, WB Baxter… - ACS Earth and Space …, 2023 - ACS Publications
Landscape-scale changes in the Arctic as a result of climate change affect the soil thermal
regime and impact the depth to permafrost in vulnerable tundra watersheds. When top-down …

A comprehensive approach to data collection, management, and visualization for terrain characterization in cold regions

WB Baxter, AJ Barker, SA Beal, LV Bosche, RR Busby… - 2024 - erdc-library.erdc.dren.mil
As global focus shifts to northern latitudes for their enhanced access to newly viable resources,
US Army operational readiness in these extreme environments is increasingly important. …
