Contraction of Information on Brain Wave Fluctuations by Information Geometrical Approach
Hidetoshi Konno · AIP conference proceedings · 2005
We will first propose a method of EEG signal identification with the use of the stochastic complex Ginzburg‐Landau (CGL) equation having complex coefficients with the aid of the method of information geometrical approach to determine the system parameters. After the contracting information on the natures of fluctuations of amplitude and phase in the EEG signals on human scalp, we combine the information with other information such as complex measures like Higuchi’s fractal dimension and multi‐scale entropies. A new theory of unification of the information is also proposed. To exhibit the potentiality of our new method, we show the result of application of the theory and method to practical EEG data from elderly sound and demented people.
