regarding the preprocessing for ICA decomposition. We thus evaluated how move-ment in EEG experiments, the number of channels, and the high-pass filter cutoff during preprocessing influence the ICA decomposition. We found that for commonly used settings (stationary experiment, 64 channels, 0.5 Hz filter), the ICA results are acceptable.

Since the number of voxel time courses decomposed (~9000) was not sufficient to derive a full (600×600) unmixing matrix, the dimensionality of the data was reduced to 100 by PCA before training. Open Ephys plugin to do ICA decomposition of LFP data and remove selected components. - tne-lab/ica-plugin of ICA decomposition of fMRI data. Mutual information (MI), an information-theoretic concept that constitutes a statistically natural measure of independence between distributions of random variables, is proven to give reliable information on the number of the underlying sources of meaningful brain activity in spatial ICA decomposition of fMRI Container for high-throughput data and results of ICA decomposition obtained on these data. IcaSet class is derived from eSet, and requires a matrix named dat as assayData member.

(2013) found that AMICA (Palmer et al., 2011) performed best among different algorithms. Independent component analysis is computational technique which is used for decomposition of multivariate signals into additive sub-components. Primary assumption for this method is that all signal ICA yields data decompositions consistent with the standard view of ERP genesis outlined above since the spatially-stable and sparsely-active components sum to the observed multichannel responses.

In any implementation of the ICA algorithm, We can distinguish three stages: Centring (subtracting the mean and creating a zero mean for the signal) Removing from the correlation (usually using the spectral decomposition of the matrix) Reducing the dimension to simplify the problem class sklearn.decomposition.
