Electroencephalogram (previous termEEG)next term has established itself as an important means of identifying and analyzing previous termepilepticnext term seizure activity in humans. In most cases, identification of the previous termepileptic EEGnext term signal is done manually by skilled professionals, who are small in number. In this paper, we try to automate the previous termdetectionnext term process. We use wavelet transform for feature extraction and obtain statistical parameters from the decomposed wavelet co-efficients. A feed-forward backpropagating artificial previous termneural networknext term (ANN) is used for the previous termclassification.next term We use genetic algorithm for choosing the training set and also implement a previous termpost-classificationnext term stage using harmonic weights to increase the accuracy. Average specificity of 99.19%, sensitivity of 91.29% and selectivity of 91.14% are obtained.
