Speech enhancement using ICA with Bessel features
Introduction The application of ICA or blind source separation to human brain electromagnetic data shows much promise The decomposition process maximizes the spatial statistical independence of the components, the idea being that the new representation of the data (ICs/TCs) reflects the “unmixed” configuration of the original spatial processes. More recently, a temporal ICA … Exploring ICA for time series decomposition Antonio Garc´ıa-Ferrer∗,EsterGonz´alez-Prieto †,andDanielPe˜na ‡ May 2011 Abstract In this paper, we apply independent component analysis (ICA) for prediction and signal extraction in multivariate time series … In the ICA stage, we used the Singular Value Decomposition (SVD) as pre-processing which involves O (m n 2) flops, where m is the number of time segments used in STFT stage. At the SVD sub-stage, we reduced the dimension of the analysis based on the desired signal variance value α . sical ICA decomposition that involves a multilinear expan-sion of the probability density function of the source. De-note the probability of the source that we are modeling by P(X), where Xis a random variable whose realizations have dimensionality d.

Independent Component Analysis (ICA) Algorithm At a high level, ICA can be broken down into the following steps. infomax ICA decomposition [8] to obtain an unmixing matrix. Multiplying the data by this matrix produced the estimated component maps and time courses.

Read more in the User Guide. Since ICA is becoming increasingly popular for EEG research, efforts have been made to identify the best algorithms and prerequisites to obtain a good decomposition of the data. Comparing different algorithms, Delorme et al. (2012) and Leutheuser et al. (2013) found that AMICA (Palmer et al., 2011) performed best among different algorithms.
Y1 - 2010/5/1. N2 - This chapter introduces and applies the concept of parallel spatial and temporal unmixing with group independent component analysis (ICA) for concurrent electroencephalography-functional magnetic resonance imaging (EEG-fMRI). window ICA decomposition strongly resembled those found by decomposition of the whole EEG epochs, suggesting that such whole epoch decomposition reveals stable independent components of EEG signals.

To characterize the magnitude of this ICA uncertainty and to understand the extent to which it may influence findings within ERP and EEG investigations, ICA decompositions of EEG data from 32 college‐aged young adults were repeated 30 times for three popular ICA algorithms.
