DAO-CP: Data-Adaptive Online CP decomposition for tensor stream

open access: yesPLoS ONE, 2022
How can we accurately and efficiently decompose a tensor stream? Tensor decomposition is a crucial task in a wide range of applications and plays a significant role in latent feature extraction and estimation of unobserved entries of data. The problem of

A video watermark algorithm based on tensor decomposition

open access: yesMathematical Biosciences and Engineering, 2019
Since most of the previous video watermark algorithms regard a video as a series of consecutive images, the embedding and extraction of watermark are performed on these images, and the correlation and redundancy among frames of a video are not considered.

Orthogonal decomposition of tensor trains [PDF]

open access: yesLinear and Multilinear Algebra, 2021
In this paper we study the problem of decomposing a given tensor into a tensor train such that the tensors at the vertices are orthogonally decomposable. When the tensor train has length two, and the orthogonally decomposable tensors at the two vertices are symmetric, we recover the decomposition by considering random linear combinations of slices ...

Detection and Denoising of Microseismic Events Using Time–Frequency Representation and Tensor Decomposition

open access: yesIEEE Access, 2018
Reliable detection and recovery of a microseismic event in large volume of passive monitoring data is usually a challenging task due to the low signal-to-noise ratio environment.

Generalized Canonical Polyadic Tensor Decomposition [PDF]

open access: yesSIAM Review, 2020
Tensor decomposition is a fundamental unsupervised machine learning method in data science, with applications including network analysis and sensor data processing. This work develops a generalized canonical polyadic (GCP) low-rank tensor decomposition that allows other loss functions besides squared error.

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

GOF/LOF knowledge inference with tensor decomposition in support of high order link discovery for gene, mutation and disease

open access: yesMathematical Biosciences and Engineering, 2019
For discovery of new usage of drugs, the function type of their target genes plays an important role, and the hypothesis of "Antagonist-GOF" and "Agonist-LOF" has laid a solid foundation for supporting drug repurposing.

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 ...

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
