Determining Number of Independent Sources in Undercomplete Mixture

EURASIP Journal on Advances in Signal Processing, 2009
Separation of independent sources using independent component analysis (ICA) requires prior knowledge of the number of independent sources. Performing ICA when the number of recordings is greater than the number of sources can give erroneous results.

Scatter Matrices and Independent Component Analysis

Austrian Journal of Statistics, 2016
In the independent component analysis (ICA) it is assumed that the components of the multivariate independent and identically distributed observations are linear transformations of latent independent components.

Imaging haemodynamic changes related to seizures: comparison of EEG-based general linear model, independent component analysis of fMRI and intracranial EEG [PDF]

, 2010
Background: Simultaneous EEG-fMRI can reveal haemodynamic changes associated with epileptic activity which may contribute to understanding seizure onset and propagation. Methods: Nine of 83 patients with focal epilepsy undergoing pre-surgical evaluation

Targeting Microbiome Metabolites: Reshaping Immunotherapy and Clinical Management Strategies for Colorectal Cancer

iMetaMed, EarlyView.
The occurrence and progression of colorectal cancer are intricately linked to metabolites produced by the gut microbiota. Metabolites generated by pathogenic microbial communities can promote colorectal cancer development by reshaping the immune microenvironment.

Microbial metabolites in tumor epigenetic regulation

iMeta, EarlyView.
The gut microbiome modulates tumor epigenetic regulation through bioactive metabolites derived from dietary substrates. Microbiota‐produced SCFAs, secondary BAs, one‐carbon metabolites, and tryptophan‐derived ligands regulate histone acetylation, DNA methylation, and chromatin remodeling via HDAC, DNMT, AhR, and metabolic cofactor‐dependent pathways ...

[Independent Components Analysis (ICA) in the study of electroencephalographic signals].

Neurologia (Barcelona, Spain), 2005
Independent Component Analysis (ICA) is a mathematical tool able to separate complex signals in statistically independent components. It solves the blind source separation problem (BSS). The EEG satisfies most of the assumptions of ICA, so it may be an adequate signal for ICA for its use.

Image metadata estimation using independent component analysis and regression [PDF]

, 2006
In this paper, we describe an approach to camera metadata estimation using regression based on Independent Component Analysis (ICA). Semantic scene classification of images using camera metadata related to capture conditions has had some success in the ...
