Robust regularized singular value decomposition with application to mortality data [PDF]

open access: yes, 2013
We develop a robust regularized singular value decomposition (RobRSVD) method for analyzing two-way functional data. The research is motivated by the application of modeling human mortality as a smooth two-way function of age group and year.

Accelerated random noise suppression of seismic data using compressed singular-value decomposition

open access: yes矿业科学学报
Random noise is one of the common background noises in seismic data, and its attenuation will directly affect the signal-to-noise ratio of seismic data, which is of great significance to improve the quality of seismic data.

Split-and-Combine Singular Value Decomposition for Large-Scale Matrix

open access: yesJournal of Applied Mathematics, 2013
The singular value decomposition (SVD) is a fundamental matrix decomposition in linear algebra. It is widely applied in many modern techniques, for example, high- dimensional data visualization, dimension reduction, data mining, latent semantic analysis,

The Singular Value Decomposition over Completed Idempotent Semifields

open access: yesMathematics, 2020
In this paper, we provide a basic technique for Lattice Computing: an analogue of the Singular Value Decomposition for rectangular matrices over complete idempotent semifields (i-SVD).

Identification of Seismic Reflections Using Singular Value Decomposition [PDF]

open access: yesModeling, Identification and Control, 1986
Singular value decomposition (SVD) is applied to the identification of seismic reflections by using two different models: the impulse response model where a seismic trace is assumed to consist of a known signal pulse convolved with a reflection ...

Statistical inference based on robust low-rank data matrix approximation

open access: yes, 2014
The singular value decomposition is widely used to approximate data matrices with lower rank matrices. Feng and He [Ann. Appl. Stat. 3 (2009) 1634-1654] developed tests on dimensionality of the mean structure of a data matrix based on the singular value ...

Very Large-Scale Singular Value Decomposition Using Tensor Train Networks [PDF]

open access: yes, 2014
We propose new algorithms for singular value decomposition (SVD) of very large-scale matrices based on a low-rank tensor approximation technique called the tensor train (TT) format. The proposed algorithms can compute several dominant singular values and

Products, coproducts and singular value decomposition

open access: yes, 2004
Products and coproducts may be recognized as morphisms in a monoidal tensor category of vector spaces. To gain invariant data of these morphisms, we can use singular value decomposition which attaches singular values, ie generalized eigenvalues, to these
