Window size analysis in ARMA-modeled spectral biomarkers for epileptic childrenWindow size analysis in ARMA-modeled spectral biomarkers for epileptic children Πλήρης Δημοσίευση σε Συνέδριο Conference Full Paper 2015-10-262008enAutoregressive Moving Average (ARMA) models are suitable for modeling processes whose frequency spectrum exhibits both sharp peaks and deep nulls. In this analysis an ARMA model was used to model EEG data and estimate its time-frequency spectrum. Spectral features were then extracted and their suitability as biomarkers for epileptic children whose EEG is clinically diagnosed as normal is analyzed. Furthermore, variations in classification are investigated when features are extracted from different window sizes. Results show that through windowing, a maximum classification score of 97.9% is achieved with an improvement of up to 18.3% over the non-windowed case.http://creativecommons.org/licenses/by/4.0/58-636th IASTED International Conference on Biomedical EngineeringBioMED '08: Proceedings of the Sixth IASTED International Conference on Biomedical Engineering Μιχελογιάννης Σήφης Micheloyannis Sifis Michelogiannis Sifis Zervakis Michail Ζερβακης Μιχαηλ Cassar Tracey Camilleri Kenneth P.
