Structural-Missing Tensor Completion for Robust DOA Estimation with Sensor Failure

open access: yesApplied Sciences, 2023
Array sensor failure poses a serious challenge to robust direction-of-arrival (DOA) estimation in complicated environments. Although existing matrix completion methods can successfully recover the damaged signals of an impaired sensor array, they cannot ...

Image Completion in Embedded Space Using Multistage Tensor Ring Decomposition

open access: yesFrontiers in Artificial Intelligence, 2021
Tensor Completion is an important problem in big data processing. Usually, data acquired from different aspects of a multimodal phenomenon or different sensors are incomplete due to different reasons such as noise, low sampling rate or human mistake.

A New Model for Tensor Completion: Smooth Convolutional Tensor Factorization

open access: yesIEEE Access, 2023
Tensor completion is the problem of filling-in missing parts of multidimensional data using the values of the reference elements. Recently, Multiway Delay-embedding Transform (MDT), which considers a low-dimensional space in a delay-embedded space with ...

Tensor Completion in Hierarchical Tensor Representations [PDF]

open access: yes, 2015
Compressed sensing extends from the recovery of sparse vectors from undersampled measurements via efficient algorithms to the recovery of matrices of low rank from incomplete information. Here we consider a further extension to the reconstruction of tensors of low multi-linear rank in recently introduced hierarchical tensor formats from a small number ...

Deterministic Tensor Completion with Hypergraph Expanders

open access: yesSIAM Journal on Mathematics of Data Science, 2021
We provide a novel analysis of low-rank tensor completion based on hypergraph expanders. As a proxy for rank, we minimize the max-quasinorm of the tensor, which generalizes the max-norm for matrices. Our analysis is deterministic and shows that the number of samples required to approximately recover an order-$t$ tensor with at most $n$ entries per ...

A Biased Deep Tensor Factorization Network For Tensor Completion

open access: yesCoRR, 2021
Tensor decomposition is a popular technique for tensor completion, However most of the existing methods are based on linear or shallow model, when the data tensor becomes large and the observation data is very small, it is prone to over fitting and the performance decreases significantly.

Missing Data Recovery Based on Tensor-CUR Decomposition

open access: yesIEEE Access, 2018
Tensor completion is a higher way analog of matrix completion, which has proven to be a powerful tool for data analysis. In this paper, we formulate the missing data recovery problem of a three-way tensor as a tensor completion problem.
