Background:

Driving fatigue poses significant safety risks, necessitating effective monitoring systems.
Electroencephalogram (EEG) signals offer a direct and reliable measure for fatigue detection.
Traditional methods often neglect brain functional connectivity and real-time processing.

Purpose of the Study:

To develop a novel, real-time driving fatigue detection model using EEG signals.
To address limitations of traditional methods by incorporating brain functional connectivity.
To improve the accuracy and efficiency of fatigue monitoring systems.

Main Methods:

Proposed an Attention-Based Multi-Semantic Dynamical Graph Convolutional Network (AMD-GCN).
Incorporated channel and spatial attention mechanisms (AM-CAM, AM-SAM) for feature weighting and noise reduction.
Utilized multi-semantic dynamical graph convolution (MD-GC) to capture complex brain network dependencies.
Concatenated Differential Entropy (DE) features from 5 and 25 frequency bands as input.

Main Results:

The AMD-GCN model achieved a high accuracy of 89.94% on the SEED-VIG dataset.
The proposed model demonstrated superior performance compared to existing algorithms for driving fatigue detection.
Attention mechanisms effectively focused on relevant EEG features and reduced interference.

Conclusions:

The developed AMD-GCN strategy offers a more effective approach for EEG-based driving fatigue detection.
The model's ability to capture functional connectivity enhances its accuracy in real-time monitoring.
This research contributes to improving road safety through advanced fatigue detection technology.
