Tikhonov regularization for weighted total least squares problems

open access: yesApplied Mathematics Letters, 2007
A general version of Tikhonov's formulation for the linear weighted total least squares (WTLS) problem has been considered by \textit{G. H. Golub} and \textit{C. F. van Loan} [SIAM J. Numer. Anal. 17, 883--893 (1980; Zbl 0468.65011)]. The present paper focus on the regularized weighted total least squares (RWTLS) formulation. It is shown that the RWTLS

On weighted total least squares adjustment for solving the nonlinear problems

open access: yesJournal of Geodetic Science, 2014
In the classical geodetic data processing, a non- linear problem always can be converted to a linear least squares adjustment. However, the errors in Jacob matrix are often not being considered when using the least square method to estimate the optimal ...

On Weighted Structured Total Least Squares [PDF]

open access: yes, 2006
In this contribution we extend our previous results on the structured total least squares problem to the case of weighted cost functions. It is shown that the computational complexity of the proposed algorithm is preserved linear in the sample size when the weight matrix is banded with bandwidth that is independent of the sample size.

Weighted total least squares formulated by standard least squares theory [PDF]

open access: yesJournal of Geodetic Science, 2012
Weighted total least squares formulated by standard least squares theoryThis contribution presents a simple, attractive, and flexible formulation for the weighted total least squares (WTLS) problem. It is simple because it is based on the well-known standard least squares theory; it is attractive because it allows one to directly use the existing body ...

Weighted Total Least Squares for Quadratic Errors-in-Variables Regression

open access: yes2023 31st European Signal Processing Conference (EUSIPCO), 2023
In this paper, we present a study on using weightedtotal least squares method for parameter estimation of errorsin-variables models with quadratic regressors. The statistics oferror is analyzed to fill in the gap between basic assumptions inweighted total least squares and our case.

Applying Monte Carlo Method for Straight-Line Model Sensor Calibration [PDF]

open access: yesSensors
Sensors are used in measurement systems to enable estimation of physical parameters. Their calibration is an essential requirement and to perform the overall system/sensor calibration, its input is changed while the output is measured. Parameters from an

Total Least Squares Spline Approximation [PDF]

open access: yesMathematics, 2019
Spline approximation, using both values y i and x i as observations, is of vital importance for engineering geodesy, e.g., for approximation of profiles measured with terrestrial laser scanners, because it enables the consideration of
