Dataset and Data Preparation

We evaluated our model using the Physionet Sleep-EDF datasets published in 2013 and 2018.
We have used the source code provided by github:akaraspt to prepare the dataset.
To download SC subjects from the Sleep_EDF (2013) dataset, use the below script:

cd data_2013
chmod +x download_physionet.sh
./download_physionet.sh

To download SC subjects from the Sleep_EDF (2018) dataset, use the below script:
```
cd data_2018
chmod +x download_physionet.sh
./download_physionet.sh
```

Use below scripts to extract sleep stages from the specific EEG channels of the Sleep_EDF (2013) dataset:

python prepare_physionet.py --data_dir data_2013 --output_dir data_2013/eeg_fpz_cz --select_ch 'EEG Fpz-Cz'
python prepare_physionet.py --data_dir data_2013 --output_dir data_2013/eeg_pz_oz --select_ch 'EEG Pz-Oz'

Train

Modify args settings in seq2seq_sleep_sleep-EDF.py for each dataset.
For example, run the below script to train SleepEEGNET model with the 20-fold cross-validation using Fpz-Cz channel of the Sleep_EDF (2013) dataset:
```
python seq2seq_sleep_sleep-EDF.py --data_dir data_2013/eeg_fpz_cz --output_dir output_2013 --num_folds 20
```

Results

Run the below script to present the achieved results by SleepEEGNet model for Fpz-Cz channel.
```
python summary.py --data_dir output_2013/eeg_fpz_cz
```

Visualization

Run the below script to visualize attention maps of a sequence input (EEG epochs) for Fpz-Cz channel.
```
python visualize.py --data_dir output_2013/eeg_fpz_cz
```
