Skew-symmetric tensor decomposition [PDF]

open access: yesCommunications in Contemporary Mathematics, 2019
We introduce the “skew apolarity lemma” and we use it to give algorithms for the skew-symmetric rank and the decompositions of tensors in [Formula: see text] with [Formula: see text] and [Formula: see text]. New algorithms to compute the rank and a minimal decomposition of a tritensor are also presented.

Tensor Decompositions in Deep Learning [PDF]

open access: yesCoRR, 2020
The paper surveys the topic of tensor decompositions in modern machine learning applications. It focuses on three active research topics of significant relevance for the community. After a brief review of consolidated works on multi-way data analysis, we consider the use of tensor decompositions in compressing the parameter space of deep learning ...

On the Decomposition of Tensors by Contraction [PDF]

open access: yesReviews of Modern Physics, 1949
The decomposition of tensors into irreducible representations of the orthogonal groups is calculated for three and four dimensions. The connection is shown with the problem of the allowed values of ordinary and isotopic spin for a given symmetry of the spacial eigenfunction of a nuclear system.

Low Tensor Rank Constrained Image Inpainting Using a Novel Arrangement Scheme

open access: yesApplied Sciences
Employing low tensor rank decomposition in image inpainting has attracted increasing attention. This study exploited novel tensor arrangement schemes to transform an image (a low-order tensor) to a higher-order tensor without changing the total number of

Geometric decomposition of the conformation tensor in viscoelastic turbulence

open access: yes, 2018
This work introduces a mathematical approach to analysing the polymer dynamics in turbulent viscoelastic flows that uses a new geometric decomposition of the conformation tensor, along with associated scalar measures of the polymer fluctuations.

Cohomology and Decomposition of Tensor Product Representations of SL(2,R) [PDF]

open access: yes, 2002
We analyze the decomposition of tensor products between infinite dimensional (unitary) and finite-dimensional (non-unitary) representations of SL(2,R). Using classical results on indefinite inner product spaces, we derive explicit decomposition formulae,

Proof of a decomposition theorem for symmetric tensors on spaces with constant curvature

open access: yes, 2008
In cosmological perturbation theory a first major step consists in the decomposition of the various perturbation amplitudes into scalar, vector and tensor perturbations, which mutually decouple.

Efficient Tensor Decompositions

open access: yes, 2020
This chapter studies the problem of decomposing a tensor into a sum of constituent rank one tensors. While tensor decompositions are very useful in designing learning algorithms and data analysis, they are NP-hard in the worst-case. We will see how to design efficient algorithms with provable guarantees under mild assumptions, and using beyond worst ...

A Color Image Watermarking Based on Tensor Analysis

open access: yesIEEE Access, 2018
Since most of the color image watermarking methods embed the watermark information in each channel or one channel of a color image, the redundant information of the color image cannot be sufficiently utilized, resulting in the poor ability to resist ...
