A New Truncation Strategy for the Higher-Order Singular Value Decomposition [PDF]
SIAM Journal on Scientific Computing, 2012 We present an alternative strategy for truncating the higher-order singular value decomposition (T-HOSVD). An error expression for an approximate Tucker decomposition with orthogonal factor matrices is presented, leading us to propose a novel truncation strategy for the HOSVD, which we refer to as the sequentially truncated higher-order singular value ...

A New Algorithm for Ill-Posed Problem of GNSS-Based Ionospheric Tomography
Remote Sensing, 2023 Ill-posedness of GNSS-based ionospheric tomography affects the stability and the accuracy of the inversion results. Truncated singular value decomposition (TSVD) is a common algorithm of ionospheric tomography reconstruction.

Fractional Norm Regularization Using Truncated Singular Value Decomposition
SSRN Electronic Journal, 2022 In a previous work, a solution to the fractional norm regularization (FNR) was discovered in a closed form and an inverse perturbation was adopted as a tool to overcome the ill condition of a matrix whose inverse is required by the fixed-point FNR. In this work, a novel computation technique, namely truncated singular value decomposition-fractional ...

An Improved Tikhonov-Regularized Variable Projection Algorithm for Separable Nonlinear Least Squares
Axioms, 2021 In this work, we investigate the ill-conditioned problem of a separable, nonlinear least squares model by using the variable projection method. Based on the truncated singular value decomposition method and the Tikhonov regularization method, we propose ...

Difference-based Methods for Truncating the Singular Value Decomposition [PDF]
Communications in Statistics - Simulation and Computation, 2015 Given a noisy time series (or signal), one may wish to remove the noise from the observed series. Assuming that the noise-free series lies in some low dimensional subspace of rank r, a common approach is to embed the noisy time series into a Hankel trajectory matrix.

Seismic Random Noise Attenuation in the Laplace Domain Using Singular Value Decomposition
IEEE Access, 2021 We attenuated incoherent seismic noise using singular value decomposition in the Laplace domain. Laplace-domain wavefields are sensitive to small-amplitude noise contaminating the first-arrival signals due to damping in the Laplace transform; this noise ...
