CHB-MIT Dataset
The CHB-MIT dataset also referred to as the PhysioNet EEG dataset,36 composed of a total of 24 pediatric patients’ EEG recordings that were was acquired at Boston Children’s Hospital. The patients suffered from intractable epilepsy, and the ages of the patients are between 1.5 years and 19 years. In the EEG data acquisition, the international 10-20 system of channel configuration with bipolar montage was used. The number of electrodes varies for different patients from 23 electrodes to 28 electrodes, whereas some electrodes were interchanged in some cases. The first 18 electrodes are similar for all of the patients. There are 198 total identified seizures and duration of the dataset is 916 hours. In the dataset, the epileptogenic source for the patients is not shown; though, the origins of epileptic sources were reported for each patient in another study conducted by Nasehi et al.37 In this dataset, the shortest seizure is 6 seconds long and

the longest seizure duration is 752 seconds. The average seizure duration is 72 seconds. Detailed description of this dataset is given in Table 4.2. The file format of the EEG time series in this dataset is. edf.
European Epileptic Dataset
There are 30 patients EEG recordings in the European Epilepsy-Database. The ages of the patients are between 13 and 67 years. In EEG data collection, the recordings are done with a 19-channel system based on the international 10—20 system channel configuration with referential montage. There are 276 seizures identified in the total 4604 hours of EEG recordings in the dataset. A summary of this dataset is provided in Table 4.3. The EEG time series are saved in .edf file format.
