On the Weighted Total Least Squares Solutions
2014Nowadays the terminology Total Least Squares (TLS) is frequently used as a standard name of the estimation method for the errors-in-variables (EIV) model. Although a significant number of contribution have been published to adjust the EIV model, the computational advantages of the TLS problem are still largely unknown.

Web image interpolation via weighted total least squares regression
2012 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2012Although ordinary least squares (OLS) regression achieves great success in clean image interpolation, its effectiveness is questionable in the scenario of web images which are usually compressed beforehand. The inherent flaw of OLS is that it is asymmetric, the perturbation is only confined on the right side of the linear system.

<p>The errors-in-variables (EIV) model is applied to surveying and mapping fields such as empirical coordinate transformation, line/plane fitting and rigorous modelling of point clouds and so on as it takes the errors both in coefficient matrix and observation vector into account.

An iterative solution of weighted total least-squares adjustment
Journal of Geodesy, 2010Total least-squares (TLS) adjustment is used to estimate the parameters in the errors-in-variables (EIV) model. However, its exact solution is rather complicated, and the accuracies of estimated parameters are too difficult to analytically compute. Since the EIV model is essentially a non-linear model, it can be solved according to the theory of non ...

Jackknife method for the location of gross errors in weighted total least squares
Communications in statistics. Simulation and computation, 2019Because the weighted total least squares (WTLS) method lacks robustness and is sensitive to gross errors, it cannot eliminate the influence of outliers effectively. A small number of gross errors may produce a devastating effect on estimates. Focusing on

Target localization based on weighted total least squares in underwater acoustic networks
International Conference on Signal Processing, Communications and Computing, 2019Most existed target localization methods in underwater sensor networks assume that the locations of sensor nodes are accurate as references to infer target location.
