Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: Nonlinear analysis of electroencephalogram (EEG) signals reflects new information in understanding of brain activity. Here, a complicated signal like EEG is considered as an output of a nonlinear dynamic system (brain). The intrinsic changes of the EEG signals are described as the variation of their fractal dimension. In this study, EEG signal complexity of ten schizophrenic patients and ten age-matched healthy participants are analyzed in two different approaches, time-domain and phase-space. In the time-domain approach, three popular methods are used to compute the complexity. In the second approach, the chaotic dynamical attractors expressed in the phase space are reconstructed and their correlation dimension (D2) which is a measure of the complexity is calculated. In this study, an efficient algorithm to calculate a time-varying dimension estimate is applied. The results indicate a diminished complexity in the EEGs of the schizophrenic patients and confirm findings associated with the fact that schizophrenic patients are characterized by less complex neurobehavioral measures than healthy participants. Finally, Support Vector Machine (SVM) is applied on the estimated fractal dimension and results show 86.4%, 81.0%, 73.9% and 70.4% classification accuracy using correlation, Higuchi, Katz and Petrosian respectively.
