Fast Kernel Summation in High Dimensions via Slicing and Fourier Transforms
Johannes Hertrich
Kernel-based methods are heavily used in machine learning. However, they suffer from complexity in the number of considered data points. In this paper, we propose an a…
Finite element simulation of fluid dynamics and CO gas exchange in the alveolar sacs of the human lung
Luis J. Caucha, Stefan Frei, Obidio Rubio
In this article we present a numerical framework based on continuum models for the fluid dynamics and the CO gas distribution in the alveolar sacs of the human lung during expi…
Overresolving in the Laplace domain for convolution quadrature methods
T. Betcke, N. Salles, W. Śmigaj
Convolution quadrature (CQ) methods have enjoyed tremendous interest in recent years as an efficient tool for solving time-domain wave problems in unbounded domains via boundary in…
A priorconditioned LSQR algorithm for linear ill-posed problems with edge-preserving regularization
Simon R. Arridge, Marta M. Betcke, Lauri Harhanen
This article presents a method for solving large-scale linear inverse problems regular- ized with a nonlinear, edge-preserving penalty term such as the total variation or Perona-Ma…
