Epilepsy is a common nervous system disorder that is described by sudden and recurrent seizures [1]. World Health Organization (WHO) statistics show that approximately 50 million people worldwide currently suffer from epilepsy [2]. Epileptic seizures are categorized into focal (also called partial), generalized, and unclassified. In the focal seizures, the abnormal electrical discharges start with a localized region, whereas in the generalized seizures, the abnormal electrical discharges start in both hemispheres of the brain simultaneously [3]. Generalized seizures are usually divided into several main types, including absence typical (petit mal), absence atypical, myoclonic, clonic, tonic, tonic-clonic (grand mal), and atonic (astatic). Focal seizures are also divided into three main types, including simple, complex, and secondarily generalized seizures [4].

However, this approach is very time-consuming, especially in the case of long-term EEG recordings that may even last for several days. As a solution, analysis of brain signals such as EEG and ElectroCorticoGram (ECoG) have been used as an important approach in the recognition of different epilepsy states. Brain signals are usually recorded in two essential ways, including 1) non-invasive recording, which is known as a scalp recording (i.e. EEG signal), and 2) invasive recording, which is often known as intra-cranial EEG (i.e. ECoG
