چکیده
Epilepsy is the neurological disorder of the brain, which is difficult to diagnose visually using electroencephalogram (EEG) signals. Our final goal of this paper is the automatic detection of the epileptic disorders in the EEG in order to support the diagnosis and care of the epileptic syndromes and related seizure disorders. We introduce a feed-forward neural network classification model with three neurons in hidden layer to classify ‘healthy subjects from epileptic seizure subjects’ and four neurons in hidden layer to classify ‘healthy subjects from epilepsy patients in seizure-free intervals from epilepsy patients with epileptic seizure’. After subtracting the average of signal from the original signal, signal obtained using double density discrete wavelet transform (DD DWT) is decomposed to five levels which are one low-pass frequency sub-band and ten high-pass frequency sub-bands. Then we extract features such as energy, entropy, sum, variance and standard deviation from ten high-pass frequency sub-bands and after that normalize them. We show that the proposed model results in very good satisfactory classificationsکلیدواژه ها

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
