Semilinear tensor decompositions

open access: yesJournal of Computational Algebra
This paper studies semilinear tensor decompositions of \(kG\)-modules, where \(G\) is a finite group and \(k\) is a field. The authors focus on \(kG\)-modules that admit a semilinear tensor decomposition, proving that this occurs if and only if the endomorphism algebra of the module contains a pair of mutually centralizing, \(G\)-invariant subalgebras ...

Co-PARAFAC: A Novel Cost-Efficient Scalable Tensor Decomposition Algorithm

open access: yesIEEE Access
This paper proposes a novel tensor decomposition method, cooperative parallel factor (Co-PARAFAC), that is devised to achieve higher accuracy with lower computational complexity and memory requirements than the conventional PARAFAC.

The average condition number of most tensor rank decomposition problems is infinite

open access: yes, 2019
The tensor rank decomposition, or canonical polyadic decomposition, is the decomposition of a tensor into a sum of rank-1 tensors. The condition number of the tensor rank decomposition measures the sensitivity of the rank-1 summands with respect to ...

Tensor Ring Decomposition

open access: yes, 2016
Tensor networks have in recent years emerged as the powerful tools for solving the large-scale optimization problems. One of the most popular tensor network is tensor train (TT) decomposition that acts as the building blocks for the complicated tensor networks.

Robust Image Hashing with Tensor Decomposition

open access: yesIEEE Transactions on Knowledge and Data Engineering, 2019
This paper presents a new image hashing that is designed with tensor decomposition (TD), referred to as TD hashing, where image hash generation is viewed as deriving a compact representation from a tensor.

Spectral Quadratic Variation Regularized Autoweighted Tensor Ring Decomposition for Hyperspectral Image Reconstruction

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
The structure information of hyperspectral image (HSI) is well-characterized by tensors, surpassing the capabilities of traditional compressive sensing reconstruction models based on vectors and matrices.

An Alternating Bayesian Approach to PARAFAC Decomposition of Tensors

open access: yesIEEE Access, 2018
The PARAllel FACtor (PARAFAC) decomposition is known as one of the most commonly used tools in tensor signal/data processing. Unfortunately, its classical algorithms barely take the potential statistical and/or deterministic prior information of the ...

Hyperspectral Image Denoising With Group Sparse and Low-Rank Tensor Decomposition

open access: yesIEEE Access, 2018
Hyperspectral image (HSI) is usually corrupted by various types of noise, including Gaussian noise, impulse noise, stripes, deadlines, and so on. Recently, sparse and low-rank matrix decomposition (SLRMD) has demonstrated to be an effective tool in HSI ...

Iterative Methods for Symmetric Outer Product Tensor Decompositions [PDF]

open access: yes, 2013
We study the symmetric outer product decomposition which decomposes a fully (partially) symmetric tensor into a sum of rank-one fully (partially) symmetric tensors. We present iterative algorithms for the third-order partially symmetric tensor and fourth-
