Web10 Jul 2024 · The gSOBI (generalized Second Order Blind Identification) method for the blind source separation (BSS) problem. The method is designed for separating multivariate time series with or without stochastic volatility. The method is a combination of SOBI and vSOBI with G(x) = x^2 as a nonlinearity function. WebIn the context of relating specific brain functions to specific brain structures, second-order blind identification (SOBI) is one of the blind source separation algorithms that have been validated extensively in the data domain of human high-density EEG.
