Local ICA and Wavelet based ICA extensions [16, 18, 19] have been introduced as a solution for these shortcomings. However, the selection of decomposition levels and reconstruction errors on spatial wavelet analysis were found to influence the accuracy and reliability of the reproduced results in clinical analysis.

Independent component analysis (ICA) is a statistical and computational technique for revealing hidden factors that underlie sets of random variables, measurements, or signals. ICA defines a generative model for the observed multivariate data, which is typically given as a large database of samples. In the model, the data variables are assumed to be linear mixtures of some unknown latent Ten spatial infomax ICA decompositions were performed on two fMRI data sets collected from the same subject. The maximallyindependent spatial components were then tested across decompositions for one-to-one correspondences. Matching independent component maps by mutual information alone proved ineffective. Matching component map pairs by correlating their z-transformed voxel map weights 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. Following each decomposition, eyeblink components were identified and removed.

ICA decomposition and subsequent postprocessing 30 separate times for each of the three ICA algorithms. Although there is a wide assortment of potential other ICA algorithms that could be investigated, these ICA algorithms represent three popular algo-rithms that are available for use with EEGLAB either in the default distribution or through a Tensor clustering: evaluate the stability of ICA decomposition by consider the infromation from both component matrix and coefficient matrix.

In this study, we compared decomposition results Infomax ICA therefore provided a stable decomposition of fMRI data into spatially independent components. Ten spatial infomax ICA decompositions were performed on two fMRI data sets collected from the same subject.

Tensor-ICA assumes that the temporal response pattern is the same across the population and provides a single decomposition for all original data sets. MELODIC will attempt to find components which are highly non-Gaussian relative to the full mixed-effects variance of the residuals. T1 - Parallel EEG-fMRI ICA Decomposition.

### Subband decomposition ICA (SDICA), an extension of ICA, assumes that each source is represented as the sum of some independent subcomponents and dependent subcomponents, which have different frequency bands. In this article, we first investigate the feasibility of separating the SDICA mixture in an adaptive manner.
