Tensor p-shrinkage nuclear norm for low-rank tensor completion [PDF]

open access: yesNeurocomputing, 2020
In this paper, a new definition of tensor p-shrinkage nuclear norm (p-TNN) is proposed based on tensor singular value decomposition (t-SVD). In particular, it can be proved that p-TNN is a better approximation of the tensor average rank than the tensor nuclear norm when p < 1.

Real Color Image Denoising Using t-Product- Based Weighted Tensor Nuclear Norm Minimization

open access: yesIEEE Access, 2019
Color images can be seen as third-order tensors with column, row and color modes. Considering two inherent characteristics of a color image including the non-local self-similarity (NSS) and the cross-channel correlation, we extract non-local similar ...

A Hybrid Norm for Guaranteed Tensor Recovery

open access: yesFrontiers in Physics, 2022
Benefiting from the superiority of tensor Singular Value Decomposition (t-SVD) in excavating low-rankness in the spectral domain over other tensor decompositions (like Tucker decomposition), t-SVD-based tensor learning has shown promising performance and

SURE Based Truncated Tensor Nuclear Norm Regularization for Low Rank Tensor Completion [PDF]

open access: yes2020 28th European Signal Processing Conference (EUSIPCO), 2021
Low rank tensor completion aims to recover the underlying low rank tensor obtained from its partial observations, this has a wide range of applications in Signal Processing and Machine Learning. A number of recent low rank tensor methods have successfully utilised the tensor singular value decomposition method with tensor nuclear norm minimisation via ...

A concise proof to the spectral and nuclear norm bounds through tensor partitions

open access: yesOpen Mathematics, 2019
On estimations of the lower and upper bounds for the spectral and nuclear norm of a tensor, Li established neat bounds for the two norms based on regular tensor partitions, and proposed a conjecture for the same bounds to be hold based on general tensor ...

Infrared Patch-Tensor Model With Weighted Tensor Nuclear Norm for Small Target Detection in a Single Frame

open access: yesIEEE Access, 2018
The robust and efficient detection of infrared small target is a key technique for infrared search and track systems. Several robust principal component analysis (RPCA)-based methods have been developed recently, which have achieved the state-of-the-art ...

Convex Recovery of Tensors Using Nuclear Norm Penalization [PDF]

open access: yes, 2015
The subdifferential of convex functions of the singular spectrum of real matrices has been widely studied in matrix analysis, optimization and automatic control theory. Convex analysis and optimization over spaces of tensors is now gaining much interest due to its potential applications to signal processing, statistics and engineering. The goal of this

Spectral norm and nuclear norm of a third order tensor

open access: yesJournal of Industrial & Management Optimization, 2022
<p style="text-indent:20px;">The spectral norm and the nuclear norm of a third order tensor play an important role in the tensor completion and recovery problem. We show that the spectral norm of a third order tensor is equal to the square root of the spectral norm of three positive semi-definite biquadratic tensors, and the square roots of the ...
