(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. ICA determines what spatially fixed and temporally independent component activations Before ICA decomposition, the one-channel signal was first divided into five segments of equal length, shown in Fig. 2 A. The five segments were input into the ICA decomposition program. The results of the ICA decomposition are shown in Fig. 2 B. It can be clearly seen from Fig. 2 B that the PLI component is present only in the fourth IC. ICA is a signal processing method capable of separating a multivariate signal into its additive subcomponents, or sources.

Typical algorithms for ICA use centering (subtract the mean to create a zero mean signal), whitening (usually with the eigenvalue decomposition), and dimensionality reduction as preprocessing steps in order to simplify and reduce the complexity of the problem for the actual iterative algorithm.

The goal of MineICA is to perform Independent Component Analysis (ICA) on multiple transcriptome datasets, integrating additional data (e.g molecular, clinical and pathological). This Integrative ICA helps the biological interpretation of the components by studying their association with variables (e.g sample annotations) and gene sets, and enables the comparison of components from different 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. Algorithms for Blind Audio Source Separation (BASS) in time domain can be categories as based on complete decomposition or based on complete decomposition. Partial decomposition of observation space leads to additional computational complexity and a confirmatory ICA decomposition is calculated using input signs vector.
