Abstract EN
Detection of epileptic seizures using an electroencephalogram (EEG) signals is a challenging task that requires a high level of skilled neurophysiologists.
Therefore, computer-aided detection provides an asset to the neurophysiologist in interpreting the EEG.
This paper introduces a novel approach to recognize and classify the epileptic seizure and seizure-free EEG signals automatically by an intelligent computer-aided method.
Moreover, the prediction of the preictal phase of the epilepsy is proposed to assist the neurophysiologist in the clinic.
The proposed method presents two perspectives for the EEG signal processing to detect and classify the seizures and seizure-free signals.
The first perspectives consider the EEG signal as a nonlinear time series.
A tunable Q-wavelet is applied to decompose the signal into smaller segments called subbands.
Then a chaotic, statistical, and power spectrum features sets are extracted from each subband.
The second perspectives process the EEG signal as an image; hence the gray-level co-occurrence matrix is determined from the image to obtain the textures of contrast, correlation, energy, and homogeneity.
Due to a large number of features obtained, a feature selection algorithm based on firefly optimization was applied.
The firefly optimization reduces the original set of features and generates a reduced compact set.
A random forest classifier is trained for the classification and prediction of the seizures and seizure-free signals.
Afterward, a dataset from the University of Bonn, Germany, is used for benchmarking and evaluation.
The proposed approach provided a significant result compared with other recent work regarding accuracy, recall, specificity, F-measure, and Matthew’s correlation coefficient.
