Decompositions of third‐order tensors: HOSVD, T‐SVD, and Beyond

Numerical Linear Algebra with Applications, 2020
SummaryThe higher order singular value decomposition, which is regarded as a generalization of the matrix singular value decomposition (SVD), has a long history and is well established, while the T‐SVD is relatively new and lacks systematic analysis. Because of the unusual tensor‐tensor product that the T‐SVD is based on, the form of the T‐SVD may be ...

SVD-Based Tensor-Completion Technique for Background Initialization

IEEE Transactions on Image Processing, 2018
Extracting the background from a video in the presence of various moving patterns is the focus of several background-initialization approaches. To model the scene background using rank-one matrices, this paper proposes a background-initialization technique that relies on the singular-value decomposition (SVD) of spatiotemporally extracted slices from ...

Online Tensor Completion and Free Submodule Tracking With The T-SVD

ICASSP 2020 - 2020 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2020
We propose a new online algorithm, called TOUCAN, for the tensor completion problem of imputing missing entries of a low tubal-rank tensor using the tensor-tensor product (t- product) and tensor singular value decomposition (t-SVD) algebraic framework.

Dynamic MRI Reconstruction Using Tensor-SVD

2018 14th IEEE International Conference on Signal Processing (ICSP), 2018
In this paper we propose to reconstruct dynamic magnetic resonance images from highly sparse sampling k-t space data by enhancing the low rankness and sparsity simultaneously. We introduce Tensor Singular Value Decomposition (t-SVD) instead of matrix SVD to maintain the structure of dynamic MR images.

Sequential Unfolding SVD for Tensors With Applications in Array Signal Processing

IEEE Transactions on Signal Processing, 2009
This paper contributes to the field of higher order (N > 2) tensor decompositions in signal processing. A novel PARATREE tensor model is introduced, accompanied with sequential unfolding SVD (SUSVD) algorithm. SUSVD, as the name indicates, applies a matrix singular value decomposition sequentially on the unfolded tensor reshaped from the right hand ...

Sequential unfolding SVD for low rank orthogonal tensor approximation

2008 42nd Asilomar Conference on Signals, Systems and Computers, 2008
This paper contributes to the field of N-way (N ges 3) tensor decompositions, which are increasingly popular in various signal processing applications. A novel PARATREE decomposition structure is introduced, accompanied with sequential unfolding SVD (SUSVD) algorithm.

Multi-view Spectral Clustering via Tensor-SVD Decomposition

2017 IEEE 29th International Conference on Tools with Artificial Intelligence (ICTAI), 2017
Multi-view clustering has attracted considerable attention in recent years, some related approaches always use matrices to represent views, and model by capturing two dimensional structure among views. The critical deficiency of these work is ignoring the space structure information of all views, which results in the mediocre performance of clustering.

Low Rank Tensor STAP filter based on multilinear SVD

2012 IEEE 7th Sensor Array and Multichannel Signal Processing Workshop (SAM), 2012
Space Time Adaptive Processing (STAP) is a two-dimensional adaptive filtering technique which uses jointly temporal and spatial dimensions to suppress disturbance and to improve target detection. Disturbance contains both the clutter arriving from signal backscattering of the ground and the thermal noise resulting from the sensors noise.
