The efficient estimation of an approximate model order is very important for real applications with multi-dimensional data if the observed low-rank data is corrupted by additive noise. In this paper, we present a novel robust method for model order estimation of noise-corrupted multi-dimensional low-rank data based on the LineAr Regression of Global Eigenvalues (LaRGE). The LaRGE method uses the multi-linear singular values obtained from the HOSVD of the measurement tensor to construct global…

Multi-dimensional model order estimation using LineAr Regression of Global Eigenvalues (LaRGE) with applications to EEG and MEG recordings

A novel robust method for model order estimation of multi-dimensional data based on the LineAr Regression of Global Eigenvalues (LaRGE) that does not require the calculation of the probability of false alarm and is well suited for the analysis of biomedical data.

Enhanced Model Order Estimation using Higher-Order Arrays

This paper shows how the HOSVD of the measurement tensor also enables us to improve the model order estimation step, due to the fact that only one set of eigenvalues is available in the matrix case.

A Reduced Complexity Tensor Approach for Order Selection and Frequency Estimation

Both theoretical analysis and experimental results demonstrate reduced computational complexity and time for the proposed CT-OS against the recent covariance tensor based order estimation algorithm CTB-OE.

Multi-dimensional model order selection

This article shows how to use tensor calculus to extend matrix-based MOS schemes and presents the proposed multi-dimensional model order selection scheme based on the closed-form PARAFAC algorithm, which is only applicable to multi- dimensional data.

Robust Multilinear Tensor Rank Estimation Using Higher Order Singular Value Decomposition and Information Criteria

New methods for improving the minimum description length (MDL) so it is more robust to noise are proposed and justified theoretically by analyzing the “multilinear low-rank structure” of tensors.

Model Order Selection for Short Data: An Exponential Fitting Test (EFT)

This paper proposes a method for noncoherent sources, which continues to work under such conditions, while maintaining low computational complexity, and allows the probability of false alarm to be controlled and predefined, which is a crucial point for systems such as RADARs.

Tensor Decompositions for Signal Processing Applications: From two-way to multiway component analysis

Benefiting from the power of multilinear algebra as their mathematical backbone, data analysis techniques using tensor decompositions are shown to have great flexibility in the choice of constraints which match data properties and extract more general latent components in the data than matrix-based methods.
