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.

Skew-symmetric tensor decomposition [PDF]

open access: yesCommunications in Contemporary Mathematics, 2019
We introduce the “skew apolarity lemma” and we use it to give algorithms for the skew-symmetric rank and the decompositions of tensors in [Formula: see text] with [Formula: see text] and [Formula: see text]. New algorithms to compute the rank and a minimal decomposition of a tritensor are also presented.

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

On the Decomposition of Tensors by Contraction [PDF]

open access: yesReviews of Modern Physics, 1949
The decomposition of tensors into irreducible representations of the orthogonal groups is calculated for three and four dimensions. The connection is shown with the problem of the allowed values of ordinary and isotopic spin for a given symmetry of the spacial eigenfunction of a nuclear system.
