Legendre decomposition for tensors*

open access: yesJournal of Statistical Mechanics: Theory and Experiment, 2019
Abstract We present a novel nonnegative tensor decomposition method, called Legendre decomposition, which factorizes an input tensor into a multiplicative combination of parameters. Thanks to the well-developed theory of information geometry, the reconstructed tensor is unique and always minimizes the KL divergence from an input tensor ...

Orthogonal Tensor Decompositions [PDF]

open access: yesSIAM Journal on Matrix Analysis and Applications, 2001
The singular value decomposition of a real \(m\times n\) matrix can be reformulated as an orthogonal decomposition in the tensor product \(\mathbb{R}^m \otimes \mathbb{R}^n\). The present paper is concerned with possible generalizations to multiple tensor products \(\mathbb{R}^{m_1} \otimes\cdots \otimes \mathbb{R}^{m_k}\), a prime consideration being ...

Channel estimation of multi-user millimeter wave massive MIMO system based on random grid tensor decomposition

open access: yes上海师范大学学报. 自然科学版, 2021
By using the sparse scattering characteristics of the millimeter wave channel and the spatial structure of the tensor, a channel estimation method based on random grid tensor decomposition was proposed.

Randomized CP tensor decomposition

open access: yesMachine Learning: Science and Technology, 2020
Abstract The CANDECOMP/PARAFAC (CP) tensor decomposition is a popular dimensionality-reduction method for multiway data. Dimensionality reduction is often sought after since many high-dimensional tensors have low intrinsic rank relative to the dimension of the ambient measurement space.

Tensor-CUR Decompositions for Tensor-Based Data [PDF]

open access: yesSIAM Journal on Matrix Analysis and Applications, 2006
Motivated by numerous applications in which the data may be modeled by a variable subscripted by three or more indices, we develop a tensor-based extension of the matrix CUR decomposition. The tensor-CUR decomposition is most relevant as a data analysis tool when the data consist of one mode that is qualitatively different from the others. In this case,

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

Tensor Ring Decomposition

open access: yesCoRR, 2016
Tensor networks have in recent years emerged as the powerful tools for solving the large-scale optimization problems. One of the most popular tensor network is tensor train (TT) decomposition that acts as the building blocks for the complicated tensor networks.
