Abstract: Brain Computer Interface (BCI) – one of the recent advancements in the field of Bioinformatics which offers a real-time support for the people, who are affected by chronic neurological disorders. Owing to the rapid progression of Electroencephalogram (EEG) – based BCI system, the detection of epileptic seizures has become much simpler. However, accurate detection through visual inspection is tedious, time-consuming and prone to error. Thus, automation has become inevitable and for automating the epileptic seizure detection, entropies are appropriate as the nature of EEG signals are complex, arrhythmic, ephemeral, and non-stationary. Several renowned entropies are widely applied, nevertheless, the existing models fail to identify the optimal parameters of the entropies which greatly influences the performance of the Machine Learning models that could make better predictions. Hence to address the aforementioned issue, this paper presents a parallel machine learning based farmland fertility algorithm which optimizes the parameters of various entropies thereby detecting Epileptic Seizures in a systematic way. A novel weighted fitness function has been designed based on Kullback-Leibler Divergence (KLD). The extracted features are further classified using state-of-the-art classifiers. The overall performance of the proposed algorithm was evaluated using the EEG dataset obtained from University of Bonn, Germany, University of Bern and Indian EEG, New Delhi and the results show the supremacy of the proposed model in terms of sensitivity, specificity, precision, F1-score, G-mean and classification accuracy.
