Neuroscience
Computer Science
Artificial Intelligence

Background:

Electroencephalography (EEG) based emotion recognition is crucial for mobile health and affective computing.
Existing methods struggle with the trade-off between complex brain dynamics modeling and computational efficiency for edge deployment.
Current approaches often overlook multi-scale temporal dynamics and hierarchical spatial brain connectivity.

Purpose of the Study:

To introduce the Multi-Scale Spatiotemporal Graph Mamba (MSGM) for efficient and robust EEG-based emotion recognition.
To address limitations in modeling complex spatiotemporal brain activity and computational overhead in existing methods.
To facilitate real-time clinical monitoring and affective interaction through edge-deployable AI.

Main Methods:

Proposed MSGM utilizes multi-window temporal segmentation for relative power spectral density (rPSD) feature extraction.
Employs bimodal global and local graphs refined by multi-depth Graph Convolutional Networks (GCNs) to model hierarchical brain connectivity.
Integrates a single-layer MSST-Mamba module for linear computational complexity and efficient state-space modeling.

Main Results:

MSGM achieved competitive accuracy and F1 scores across SEED, THU-EP, and FACED datasets under subject-independent protocols (e.g., 83.43% accuracy on SEED).
Demonstrated millisecond-level inference (151 ms) on an NVIDIA Jetson Xavier NX edge device, confirming real-time suitability.
Showcased robust generalization and efficiency due to the single MSST-Mamba layer architecture.

Conclusions:

MSGM effectively captures complex spatiotemporal brain dynamics with low computational overhead, suitable for real-time applications.
The framework integrates neuroanatomical priors into state-space modeling for improved accuracy and interpretability.
Future work will focus on multimodal integration and optimizing hierarchical spatial modeling for cross-subject variability.
