README

This repository is the official implementation of "MAtt: A Manifold Attention Network for EEG Decoding, NeurIPS 2022".

MAtt is a novel manifold attention network applied in decoding complex EEG signals. It executes the forward procedure on both Euclidean space and SPD manifold while performing backpropagation on Stiefel manifold. For more details of MAtt, please refer to our paper: 'MAtt: A Manifold Attention Network for EEG Decoding, NeurIPS 2022'.

Requirements

Step 1:

To install requirements:

conda env create -f /path/to/mAtt_env.yml
conda activate mAtt_env

Step 2:

Create a new empty folder 'data' in this folder. Download datasets and unzip them to the folder 'data'.

Dataset

1. BCIC-IV-2a: https://www.bbci.de/competition/iv/
2. MAMEM-SSVEP-II: https://www.mamem.eu/results/datasets/
3. BCI-ERN: https://www.kaggle.com/competitions/inria-bci-challenge/data

Link to download data

Training and testing

To train and test the mAtt in the paper, run this command:

python mAtt_<which_dataset>.py

All default hyperparameters are already set in files. 'which_dataset' can be chosen as 'bci' (BCIC-IV-2a), 'mamem' (MAMEM-SSVEP-II), or 'bcicha' (BCI-ERN).
