A deep learning model for automatic sleep stage scoring based on raw, single-channel EEG.
We have published a more efficient deep learning model, named TinySleepNet, which is much smaller and can achieve a better scoring performance.

Code for the model in the paper DeepSleepNet: a Model for Automatic Sleep Stage Scoring based on Raw Single-Channel EEG by Akara Supratak, Hao Dong, Chao Wu, Yike Guo from Data Science Institute, Imperial College London.
This work has been accepted for publication in IEEE Transactions on Neural Systems and Rehabilitation Engineering.
You can also find our accepted version before the publication in arXiv.
The architecture of DeepSleepNet:
Note: Fs is the sampling rate of the input EEG signals
This figure illustrates one interpretable LSTM cell from the model, which learn to keep track when each subject is awake (i.e., in W stage):
The following setup has been used to reproduce this work:
- Ubuntu 18.04 / Windows 10 1903 x64
- CUDA toolkit 10.0 and CuDNN v7.6.4
- Python 3.5.4 x64
- tensorflow-gpu (1.15.2)
- matplotlib (1.5.3)
- scikit-learn (0.19.1)
- scipy (1.4.1)
- numpy (1.18.2)
- pandas (0.25.3)
- mne (0.20.0)
- tensorlayer (optional)
- MongoDB (optional)
- eAE (optional)
We evaluated our DeepSleepNet with MASS and Sleep-EDF dataset.
For the MASS dataset, you have to request for a permission to access their dataset. For the Sleep-EDF dataset, you can run the following scripts to download SC subjects.
cd data
chmod +x download_physionet.sh
./download_physionet.sh
Then run the following script to extract specified EEG channels and their corresponding sleep stages.
python prepare_physionet.py --data_dir data --output_dir data/eeg_fpz_cz --select_ch 'EEG Fpz-Cz'
python prepare_physionet.py --data_dir data --output_dir data/eeg_pz_oz --select_ch 'EEG Pz-Oz'
Run this script to train a DeepSleepNet model for the first fold of the 20-fold cross-validation.
python train.py --data_dir data/eeg_fpz_cz --output_dir output --n_folds 20 --fold_idx 0 --pretrain_epochs 100 --finetune_epochs 200 --resume False
You need to train a DeepSleep model for every fold (i.e., fold_idx=0...19) before you can evaluate the performance. You can use the following script to run batch training
chmod +x batch_train.sh
./batch_train.sh data/eeg_fpz_cz/ output 20 0 19 0
Run this script to determine the sleep stages for the withheld subject for each cross-validation fold.
python predict.py --data_dir data/eeg_fpz_cz --model_dir output --output_dir output
The output will be stored in numpy files.
Run this script to show a summary of the performance of our DeepSleepNet compared with the state-of-the-art hand-engineering approaches. The performance metrics are overall accuracy, per-class F1-score, and macro F1-score.
python summary.py --data_dir output
- Setup an eAE cluster (follows the instruction in this link)
- Setup a MongoDB
- Change location of MongoDB in
deepsleep/trainer.py - Modify
submit_eAE.py - Run
python submit_eAE.py
- Release a version that does not depend on MongoDB and Tensorlayer (easier to install, but could take longer time for training).
