Abstract
This paper proposes a novel weighted extreme learning machine (WELM) classifier using binary cuckoo search (BCS) optimization algorithm for a fast and efficient detection of the epileptic seizure and seizure-free epochs exploiting simple temporal features. The proposed WELM based model assigns variable weights to different classes (seizure and non-seizure) to handle the biased-data problem generally found in EEG data. Moreover, BCS optimization algorithm is incorporated to choose good features for the improvement of the accuracy of the model as well as to reduce the classification time. A comparative study of the suggested model with three benchmark classifiers [Extreme learning machine (ELM), Support vector machine (SVM), and K-Nearest Neighbours (KNN)] is shown using a popular publicly available database: CHB-MIT Scalp EEG database. The average accuracy, sensitivity, and specificity of the proposed model are 99.06%, 97.97%, and 99.6% respectively. The experimental results indicate that the suggested method has a very low false prediction rate and it outperforms existing state of art methods. Hence, this developed approach has proved itself as a fast and robust patient-specific model to detect epileptic seizure and seizure-free epochs.
