A Coincidence-Filtering-Based Approach for CNNs in EEG-Based Recognition

Electroencephalogram (EEG), obtained by wearable devices, can realize effective human health monitoring. Traditional methods based on artificially designed features have achieved valid results in EEG-based recognition, and numerous studies start to apply deep learning techniques in this area. In this article, we propose a coincidence-filtering-based method to build a connection between artificial-features-based methods and convolutional neural networks (CNNs), and design CNNs through simulating the information extraction pattern of artificial-features-based methods. Based on this method, we propose a novel, simple, and effective CNNs structure for EEG-based classification. We implement two experiments to obtain EEG data, and perform experiments based on the two health monitoring tasks. The results illustrate that the proposed network can achieve a prominent average accuracy on the emotion recognition and fatigue driving detection task. Due to its generality, the proposed framework design of CNNs is expected to be useful for broader applications in health monitoring areas.
