This document proposes a method to detect epileptic seizures from EEG signals using wavelet decomposition and entropy-based feature extraction. EEG data is decomposed using wavelets and features like entropy measures and power ratios in different frequency bands are extracted. These features are then used as inputs to a k-nearest neighbors classifier to classify signals as normal, ictal or inter-ictal. The method is tested on two benchmark EEG databases and aims to increase prediction accuracy of seizure onset to help localize epileptic foci. Statistical, spectral and nonlinear features are commonly used in existing methods. The proposed method uses entropy measures like Shannon, Renyi, approximate and sample entropy along with power ratios in frequency bands as features for classification.
