EEG-KD

This repository is the official implementation of "Enhancing Low-Density EEG-Based Brain-Computer Interface with Knowledge Distillation".

Requirements

Step 1:

To install requirements:

git clone https://github.com/CECNL/EEG-KD.git
cd EEG-KD
conda env create -f KD.yaml
conda activate KD

Step 2:

Download dataset and put them to the folder "BCICIV_2a".

Training and testing

To train the teacher model or baseline student model (w/o KD), run this command:

python train_teacher.py --model SCCNet22 --save_folder ./savedata/SCCNet22

To train the student model, run this command:

python train_student.py --alpha 0.9 --beta 450 --save_folder ./savedata/SK --teacher_model SCCNet22 --teacher_folder ./savedata/SCCNet22
