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 ...

Tensor‐based matched‐field processing applied to the SWellEx‐96 data

open access: yesElectronics Letters, 2023
This study proposed a matched field source localization method based on tensor decomposition. By considering the advantages of tensors in multidimensional data processing, a three‐dimensional tensor signal model of space‐time‐frequency is constructed ...

Randomized Tensor Ring Decomposition and Its Application to Large-scale Data Reconstruction

open access: yes, 2019
Dimensionality reduction is an essential technique for multi-way large-scale data, i.e., tensor. Tensor ring (TR) decomposition has become popular due to its high representation ability and flexibility.

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 ...

Orthogonal random projection for tensor completion

open access: yesIET Computer Vision, 2020
The low‐rank tensor completion problem, which aims to recover the missing data from partially observable data. However, most of the existing tensor completion algorithms based on Tucker decomposition cannot avoid using singular value decomposition (SVD ...

Spectral Methods from Tensor Networks

open access: yes, 2018
A tensor network is a diagram that specifies a way to "multiply" a collection of tensors together to produce another tensor (or matrix). Many existing algorithms for tensor problems (such as tensor decomposition and tensor PCA), although they are not ...

Empirical Evaluation of Four Tensor Decomposition Algorithms [PDF]

open access: yes, 2007
Higher-order tensor decompositions are analogous to the familiar Singular Value Decomposition (SVD), but they transcend the limitations of matrices (second-order tensors).
