| Abstract(in English) | Independent component analysis (ICA) is a new kind of algorithm used for separating mixed sources. Here we study the influence of the updating block size on the convergence of ICA algorithms, for stationary and non-stationary data. We found that ICA algorithms with a small enough number of observations: a) do not necessarily converge to a solution which cancels the mixing effect; b) depend on the initial estimated parameters; c) separate more than one Gaussian source. |
