Block-Term Tensor Decomposition Model Selection and Computation: The Bayesian Way

no code implementations8 Jan 2021 Paris V. Giampouras, Athanasios A. Rontogiannis, Eleftherios Kofidis

The so-called block-term decomposition (BTD) tensor model, especially in its rank-$(L_r, L_r, 1)$ version, has been recently receiving increasing attention due to its enhanced ability of representing systems and signals that are composed of \emph{blocks} of rank higher than one, a scenario encountered in numerous and diverse applications.

Early soft and flexible fusion of EEG and fMRI via tensor decompositions

no code implementations12 May 2020 Christos Chatzichristos, Eleftherios Kofidis, Lieven De Lathauwer, Sergios Theodoridis, Sabine Van Huffel

The fusion methods reported so far ignore the underlying multi-way nature of the data in at least one of the modalities and/or rely on very strong assumptions about the relation of the two datasets.

Higher-Order Block Term Decomposition for Spatially Folded fMRI Data

no code implementations15 Jul 2016 Christos Chatzichristos, Eleftherios Kofidis, Giannis Kopsinis, Sergios Theodoridis

The growing use of neuroimaging technologies generates a massive amount of biomedical data that exhibit high dimensionality.

Blind Source Separation: Fundamentals and Recent Advances (A Tutorial Overview Presented at SBrT-2001)

no code implementations9 Mar 2016 Eleftherios Kofidis

Blind source separation (BSS), i. e., the decoupling of unknown signals that have been mixed in an unknown way, has been a topic of great interest in the signal processing community for the last decade, covering a wide range of applications in such diverse fields as digital communications, pattern recognition, biomedical engineering, and financial data analysis, among others.
