This repository contains groups of scripts written as a part of fNIRS, EEG classification research for the state-of-the-art deep learning application.
"Brain State Classification on Functional Near Infrared Spectroscopy using Convolutional Neural Networks"
Andrew Lee, Jim (Euiyoung) Chung, Xiaofu He
The main project in progress. Our lab is planning finalize the paper soon and the source code will be updated after the paper is published.
TensorFlow and Keras implementation of Zhang et al(2018), "EEG-based Intention Recognition from Spatio-Temporal Representations via Cascade and Parallel Convolutional Recurrent Neural Networks" for EEG motar imagery classification on PhysioNet data (https://archive.physionet.org/pn4/eegmmidb/). Stacked CNN and RNN were applied on time-distributed sliding windows of raw EEG data.
