Rank-Adaptive Tensor Completion Based on Tucker Decomposition [PDF]

open access: yesEntropy, 2023
Tensor completion is a fundamental tool to estimate unknown information from observed data, which is widely used in many areas, including image and video recovery, traffic data completion and the multi-input multi-output problems in information theory ...

L1-Norm Tucker Tensor Decomposition [PDF]

open access: yesIEEE Access, 2019
Tucker decomposition is a standard multi-way generalization of Principal-Component Analysis (PCA), appropriate for processing tensor data. Similar to PCA, Tucker decomposition has been shown to be sensitive against faulty data, due to its L2-norm-based ...

Multimodal Tucker Decomposition for Gated RBM Inference [PDF]

open access: yesApplied Sciences, 2021
Gated networks are networks that contain gating connections in which the output of at least two neurons are multiplied. The basic idea of a gated restricted Boltzmann machine (RBM) model is to use the binary hidden units to learn the conditional ...

VOLUME-REGULARIZED NONNEGATIVE TUCKER DECOMPOSITION WITH IDENTIFIABILITY GUARANTEES. [PDF]

open access: yesProc IEEE Int Conf Acoust Speech Signal Process, 2023
It is well-known that the Tucker decomposition of a multi-dimensional tensor is not unique, because its factors are subject to rotation ambiguities similar to matrix factorization models. Inspired by the recent success in the identifiability of nonnegative matrix factorization, the goal of this work is to achieve similar results for nonnegative Tucker ...

Muscle Synergy during Wrist Movements Based on Non-Negative Tucker Decomposition [PDF]

open access: yesSensors
Modular control of the muscle, which is called muscle synergy, simplifies control of the movement by the central nervous system. The purpose of this study was to explore the synergy in both the frequency and movement domains based on the non-negative ...

Efficient enhancement of low-rank tensor completion via thin QR decomposition [PDF]

open access: yesFrontiers in Big Data
Low-rank tensor completion (LRTC), which aims to complete missing entries from tensors with partially observed terms by utilizing the low-rank structure of tensors, has been widely used in various real-world issues.

Image Clustering Algorithm Based on Hypergraph Regularized Nonnegative Tucker Decomposition [PDF]

open access: yesJisuanji gongcheng, 2022
The internal geometry structure of high-dimensional data is ignored when nonnegative tensor decomposition is applied to image clustering.To solve this problem, we propose a Hypergraph regularized Nonnegative Tucker Decomposition(HGNTD) model by adding a ...

Orthogonal Nonnegative Tucker Decomposition [PDF]

open access: yesSIAM Journal on Scientific Computing, 2021
In this paper, we study the nonnegative tensor data and propose an orthogonal nonnegative Tucker decomposition (ONTD). We discuss some properties of ONTD and develop a convex relaxation algorithm of the augmented Lagrangian function to solve the optimization problem. The convergence of the algorithm is given.
