Hankel Tensor Decompositions and Ranks [PDF]

open access: yesSIAM Journal on Matrix Analysis and Applications, 2019
Hankel tensors are generalizations of Hankel matrices. This article studies the relations among various ranks of Hankel tensors. We give an algorithm that can compute the Vandermonde ranks and decompositions for all Hankel tensors. For a generic $n$-dimensional Hankel tensor of even order or order three, we prove that the the cp rank, symmetric rank ...

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

Knowledge Graph Reasoning Based on Tensor Decomposition and MHRP-Learning

open access: yesAdvances in Multimedia, 2021
In the process of learning and reasoning knowledge graph, the existing tensor decomposition technology only considers the direct relationship between entities in knowledge graph. However, it ignores the characteristics of the graph structure of knowledge

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 ...

A tensor compression algorithm using Tucker decomposition and dictionary dimensionality reduction

open access: yesInternational Journal of Distributed Sensor Networks, 2020
Tensor compression algorithms play an important role in the processing of multidimensional signals. In previous work, tensor data structures are usually destroyed by vectorization operations, resulting in information loss and new noise. To this end, this

Decomposition of Elasticity Tensor on Material Constants and Mesostructures of Metal Plates

open access: yesCrystals
Most metal plates are orthorhombic aggregates of cubic crystallites. First, we discuss the representations of the stress tensor, the strain tensor, the elasticity tensor, and the rotation tensor under the Kelvin notation.

L1-Norm Tucker Tensor Decomposition

open access: yesIEEE Access, 2019
Tucker decomposition is a standard multi-way generalization of Principal-Component Analysis (PCA), appropriate for processing tensor data. Similar to PCA, Tucker decomposition has been shown to be sensitive against faulty data, due to its L2-norm-based ...
