Stochastic rounding: implementation, error analysis and applications [PDF]

open access: yesRoyal Society Open Science, 2022
Stochastic rounding (SR) randomly maps a real number x to one of the two nearest values in a finite precision number system. The probability of choosing either of these two numbers is 1 minus their relative distance to x.

Design and Implementation of Multithreaded Reproducible DGEMV for Phytium Processor [PDF]

open access: yesJisuanji kexue, 2022
In high-performance computing,the accumulation of rounding error in the process of solving the large-scale,long time and ill-conditioned problem will lead to invalidated results.These results are useful for the developers to debug programs and check ...

A High-Order Kalman Filter Method for Fusion Estimation of Motion Trajectories of Multi-Robot Formation

open access: yesSensors, 2022
Multi-robot motion and observation generally have nonlinear characteristics; in response to the problem that the existing extended Kalman filter (EKF) algorithm used in robot position estimation only considers first-order expansion and ignores the higher-

Analysis and application of real-time compensation of positioning precision of the turntable with a harmonic function [PDF]

open access: yesMetrology and Measurement Systems, 2022
In order to guarantee the accuracy of turntable angle measurement, a real-time compensation method for turntable positioning precision based on harmonic analysis is proposed in this paper.

Statistical Analysis of Rounded Data: Measurement Errors vs Rounding Errors [PDF]

open access: yesJournal of Mathematical Sciences, 2018
Consider the measurements in which the discretization step is constant and without loss of generality is equal to 1. The measured value \(X\) is rounded to the closest integer \(X^*\) according to the rule \(X^*=[X+0.5]\) where \([x]\) is the integer part of \(x\). Measurements of the quantity \(\mu\) are considered as i.i.d. random samples \(X_1,\dots,

Algorithm for Calculating Primary Spectral Density Estimates Using FFT and Analysis of its Accuracy

open access: yesКібернетика та комп'ютерні технології, 2022
Introduction. Fast algorithms for solving problems of spectral and correlation analysis of random processes began to appear mainly after 1965, when the algorithm of fast Fourier transform (FFT) entered computational practice.
