Journal ArticleDOI

Removing electroencephalographic artifacts by blind source separation.

TL;DR: The results on EEG data collected from normal and autistic subjects show that ICA can effectively detect, separate, and remove contamination from a wide variety of artifactual sources in EEG records with results comparing favorably with those obtained using regression and PCA methods.
Journal ArticleDOI

Independent component analysis using an extended infomax algorithm for mixed subgaussian and supergaussian sources

TL;DR: An extension of the infomax algorithm of Bell and Sejnowski (1995) is presented that is able blindly to separate mixed signals with sub- and supergaussian source distributions and is effective at separating artifacts such as eye blinks and line noise from weaker electrical signals that arise from sources in the brain.
Journal ArticleDOI

Dictionary learning algorithms for sparse representation

TL;DR: Algorithms for data-driven learning of domain-specific overcomplete dictionaries are developed to obtain maximum likelihood and maximum a posteriori dictionary estimates based on the use of Bayesian models with concave/Schur-concave negative log priors, showing improved performance over other independent component analysis methods.
Book

Independent Component Analysis: Theory and Applications

TL;DR: This work presents a Unifying Information-Theoretic Framework for ICA, a novel and scalable framework for independent component analysis that combines supervised and unsupervised classification with ICA Mixture Models.
Journal ArticleDOI

Imaging brain dynamics using independent component analysis

TL;DR: The assumptions underlying ICA are outlined and its application to a variety of electrical and hemodynamic recordings from the human brain is demonstrated.
