Methods of Combating the Accumulation of Rounding Error When Solving Problems of Trans-Computational Complexity

open access: yesКібернетика та комп'ютерні технології
Introduction. The main attention is paid to the need to take into account estimates of rounding errors when solving problems of transcomputational complexity.

Rounding error analysis of linear recurrences using generating series

open access: yesETNA - Electronic Transactions on Numerical Analysis, 2023
We develop a toolbox for the error analysis of linear recurrences with constant or polynomial coefficients, based on generating series, Cauchy's method of majorants, and simple results from analytic combinatorics. We illustrate the power of the approach by several nontrivial application examples. Among these examples are a new worst-case analysis of an

Analysis of the Quantization Noise in Discrete Wavelet Transform Filters for 3D Medical Imaging

open access: yesApplied Sciences, 2020
Denoising and compression of 2D and 3D images are important problems in modern medical imaging systems. Discrete wavelet transform (DWT) is used to solve them in practice.

Rounding-Error Analysis of Multigrid \({V}\)-Cycles

open access: yesSIAM Journal on Scientific Computing
Abstract. Earlier work on rounding-error analysis of multigrid was restricted to cycles that used one relaxation step before coarsening and none afterwards. The present paper extends this analysis to two-grid methods that use one relaxation step both before and after coarsening.

Estimating and modelling bias of the hierarchical partitioning public-domain software: implications in environmental management and conservation. [PDF]

open access: yesPLoS ONE, 2010
BACKGROUND: Hierarchical partitioning (HP) is an analytical method of multiple regression that identifies the most likely causal factors while alleviating multicollinearity problems. Its use is increasing in ecology and conservation by its usefulness for

Rounding error analysis for forward continued fraction algorithms

open access: yesComputers & Mathematics with Applications, 1985
From authors' summary: There exist several algorithms for the calculation of a continued fraction. We will investigate the effect of data perturbations and rounding errors for some algorithms, using the ideas of Stummel's perturbation theory which is a forward error analysis.

A posteriori error analysis of round-off errors in the numerical solution of ordinary differential equations [PDF]

open access: yesNumerical Algorithms, 2017
We prove sharp, computable error estimates for the propagation of errors in the numerical solution of ordinary differential equations. The new estimates extend previous estimates of the influence of data errors and discretisation errors with a new term accounting for the propagation of numerical round-off errors, showing that the accumulated round-off ...
