Literature survey on low rank approximation of matrices
, 2016 Low rank approximation of matrices has been well studied in literature. Singular value decomposition, QR decomposition with column pivoting, rank revealing QR factorization (RRQR), Interpolative decomposition etc are classical deterministic algorithms ...

A note on a new matrix decomposition
Linear Algebra and its Applications, 1974 AbstractIt is shown that if det A=±1, then A=±qi=1Bi, where Bi2 = I. This decomposition is used to find the Jacobian of the linear matrix transformation: Y=AX.

Advanced Engineering Materials, EarlyView.Scanning transmission electron microscopy imaging techniques are an essential tool to document dynamic developments, such as precipitation in aluminum alloys, during in situ heating experiments using transmission electron microscopy. However, in many cases, chemical information is required to interpret complex nanoscale processes.

Modifying the Yamaguchi Four-Component Decomposition Scattering Powers Using a Stochastic Distance
, 2015 Model-based decompositions have gained considerable attention after the initial work of Freeman and Durden. This decomposition which assumes the target to be reflection symmetric was later relaxed in the Yamaguchi et al.

Coherency Matrix Decomposition-Based Polarimetric Persistent Scatterer Interferometry
IEEE Transactions on Geoscience and Remote Sensing, 2019 The rationale of polarimetric optimization techniques is to enhance the phase quality of the interferograms by combining adequately the different polarization channels available to produce an improved one.

A System of Four Generalized Sylvester Matrix Equations over the Quaternion Algebra
MathematicsIn this paper, we make use of the simultaneous decomposition of eight quaternion matrices to study the solvability conditions and general solutions to a system of two-sided coupled Sylvester-type quaternion matrix equations AiXiCi+BiXi+1Di=Ωi,i=1,2,3,4 ...

Incomplete Multi-View Clustering Based on Dynamic Dimensionality Reduction Weighted Graph Learning
IEEE AccessAiming at the existing incomplete multi-view clustering methods that usually ignore the noise and redundancy of the original data, hide the valuable information in the missing views, and the different importance of each view, this paper proposes the ...
