چکیده

‘I’hc truncated singular value decomposition (SW) is considered as a method for rcgularization of ill-posed linear lcast squares pro&ins. In particular, the .truncatcd SVl> solution is compared wi th the usua l rcguiarizcd so.lution. Ncccssary conditions arc d&cd in which the two m&hods will yield similar results. This investigation suggests the truncated SW as n filvorablc al-. tcrnativc to st;lndard-form rcgularization in cast of ill-conditioned matrices with a well-dctcrmincd rank.

Large-scale Inversion of Magnetic Data Using Golub-Kahan Bidiagonalization with Truncated Generalized Cross Validation for Regularization Parameter Estimation

In this paper a fast method for large-scale sparse inversion of magnetic data is considered. The L1-norm stabilizer is used to generate models with sharp and distinct interfaces. To deal with the non-linearity introduced by the L1-norm, a model-space iteratively reweighted least squares algorithm is used. The original model matrix is factorized using the Golub-Kahan bidiagonalization that proje...

روش‌های تجزیه مقادیر منفرد منقطع و تیخونوف تعمیم‌یافته در پایدارسازی مسئله انتقال به سمت پائین

The methods applied to regularization of the ill-posed problems can be classified under “direct” and “indirect” methods. Practice has shown that the effects of different regularization techniques on an ill-posed problem are not the same, and as such each ill-posed problem requires its own investigation in order to identify its most suitable regularization method. In the geoid computations witho...

The Use of the L-Curve in the Regularization of Discrete Ill-Posed Problems

Regularization algorithms are often used to produce reasonable solutions to ill-posed problems. The L-curve is a plot-for all valid regularization parameters-of the size of the regularized solution versus the size of the corresponding residual. Two main results are established. First a unifying characterization of various regularization methods is given and it is shown that the measurement of "...

Dynamical systems gradient method for solving ill-conditioned linear algebraic systems

A version of the Dynamic Systems Method for solving ill-conditioned linear algebraic systems is studied in this paper. An a priori and a posteriori stopping rules are justified. Algorithms for computing the solution in the case when SVD of the lefthand side matrix is available is presented. Numerical results show that when SVD of the left-hand side matrix is available or not computationally exp...

Regularization with Randomized SVD for Large-Scale Discrete Inverse Problems

In this paper we propose an algorithm for solving the large-scale discrete ill-conditioned linear problems arising from the discretization of linear or nonlinear inverse problems. The algorithm combines some existing regularization techniques and regularization parameter choice rules with a randomized singular value decomposition (SVD) so that only much smaller-scale systems are needed to solve...
