A tensor norm approach to quantum compatibility [PDF]

open access: yesJournal of Mathematical Physics, 2022
Measurement incompatibility is one of the most striking examples of how quantum physics is different from classical physics. Two measurements are incompatible if they cannot arise via classical post-processing from a third one. A natural way to quantify incompatibility is in terms of noise robustness. In the present article, we review recent results on

Tensor Completion Based on Triple Tubal Nuclear Norm

open access: yesAlgorithms, 2018
Many tasks in computer vision suffer from missing values in tensor data, i.e., multi-way data array. The recently proposed tensor tubal nuclear norm (TNN) has shown superiority in imputing missing values in 3D visual data, like color images and videos ...

Symmetric Tensor Decomposition by an Iterative Eigendecomposition Algorithm [PDF]

open access: yes, 2016
We present an iterative algorithm, called the symmetric tensor eigen-rank-one iterative decomposition (STEROID), for decomposing a symmetric tensor into a real linear combination of symmetric rank-1 unit-norm outer factors using only eigendecompositions ...

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 ...

A parallel multi‐block alternating direction method of multipliers for tensor completion

open access: yesIET Image Processing, 2021
This paper proposes an algorithm for the tensor completion problem of estimating multi‐linear data under the limitation of observation rate. Many tensor completion methods are based on nuclear norm minimization, they may fail to achieve the global ...

Alternating Direction Method of Multipliers for Generalized Low-Rank Tensor Recovery

open access: yesAlgorithms, 2016
Low-Rank Tensor Recovery (LRTR), the higher order generalization of Low-Rank Matrix Recovery (LRMR), is especially suitable for analyzing multi-linear data with gross corruptions, outliers and missing values, and it attracts broad attention in the fields

Decomposing Overcomplete 3rd Order Tensors using Sum-of-Squares Algorithms [PDF]

open access: yes, 2015
Tensor rank and low-rank tensor decompositions have many applications in learning and complexity theory. Most known algorithms use unfoldings of tensors and can only handle rank up to $n^{\lfloor p/2 \rfloor}$ for a $p$-th order tensor in $\mathbb{R}^{n ...

Vanishing theorems for higher-order Killing and Codazzi

open access: yesДифференциальная геометрия многообразий фигур, 2019
A Killing p-tensor (for an arbitrary natural number p ≥ 2) is a sym­metric p-tensor with vanishing symmetrized covariant derivative. On the other hand, Codazzi p-tensor is a symmetric p-tensor with symmetric co­variant derivative. Let M be a complete and

Some Generalized Versions of Chevet–Saphar Tensor Norms

open access: yesMathematics, 2022
The paper is concerned with some generalized versions gE and wE of classical tensor norms. We find a Banach space E for which gE and wE are finitely generated tensor norms, and show that gE and wE are associated with the ideals of some E-nuclear ...
