USE OF CORRELATION ANALYSIS FOR ONSET EPILEPTIC SEIZURE DETECTION

English version České info

In this paper we present our implementation of correlation analysis method used for detecting epileptic seizures during their onset zone. We used matrices of correlation coefficients and their time course to classify seizure. We also developed effective method to reduce number of features. Implemented algorithms were tested on our own dataset acquired in cooperation with the neurological department of FN Motol. The results show this approach as reasonable but the accuracy must be significantly improved before use in practice.
