Multiresolution kernel matrix algebra
H. Harbrecht, M. Multerer, O. Schenk +1
We propose a sparse algebra for samplet compressed kernel matrices, to enable efficient scattered data analysis. We show the compression of kernel matrices by means of samplets pro…
Level-based Blocking for Sparse Matrices: Sparse Matrix-Power-Vector Multiplication
Christie L. Alappat, Georg Hager, Olaf Schenk +1
The multiplication of a sparse matrix with a dense vector (SpMV) is a key component in many numerical schemes and its performance is known to be severely limited by main memory acc…
Parallelized integrated nested Laplace approximations for fast Bayesian inference
Lisa Gaedke-Merzhäuser, Janet van Niekerk, Olaf Schenk +1
There is a growing demand for performing larger-scale Bayesian inference tasks, arising from greater data availability and higher-dimensional model parameter spaces. In this work w…
