Tucker Tensor analysis of Matern functions in spatial statistics
Alexander Litvinenko, David Keyes, Venera Khoromskaia +2
In this work, we describe advanced numerical tools for working with multivariate functions and for the analysis of large data sets. These tools will drastically reduce the required…
Quantized-CP Approximation and Sparse Tensor Interpolation of Function Generated Data
Boris N. Khoromskij, Kishore K. Naraparaju, Jan Schneider
In this article we consider the iterative schemes to compute the canonical (CP) approximation of quantized data generated by a function discretized on a large uniform grid in an in…
Block circulant and Toeplitz structures in the linearized Hartree-Fock equation on finite lattices: tensor approach
V. Khoromskaia, B. N. Khoromskij
This paper introduces and analyses the new grid-based tensor approach to approximate solution of the elliptic eigenvalue problem for the 3D lattice-structured systems. We consider…
