Existing work in the field of BCI treats deep learning models as black-box classifiers. In this project, we develop a novel model named "InterpretableCNN" that allows sample wise analysis of important features for classification. The model not only achieves SOTA classification accuracy of EEG signals but also reveals meaningful features from EEG.

The project contains 3 code files. They are implemented with Python 3.6.6.

"InterpretableCNN.py" contains the model. required library: torch

"LeaveOneOut_acc.py" contains the leave-one-subject-out method to get the classifcation accuracies. It requires the computer to have cuda supported GPU installed. required library:torch,scipy,numpy,sklearn

"VisTechnique.py" contains the novel visualization technique proposed in the paper. It requires the computer to have cuda supported GPU installed. required library:torch,scipy,numpy,matplotlib,mne

The processed dataset has been uploaded to: https://figshare.com/articles/dataset/EEG_driver_drowsiness_dataset/14273687
