    This study introduces an explainable cross-level topological network (ECTN) for improved electroencephalogram (EEG) emotion recognition. The ECTN model effectively captures channel- and region-level brain interactions, outperforming existing methods.

    Area of Science:

    • Neuroscience
    • Machine Learning
    • Biomedical Engineering

    Background:

    • Electroencephalogram (EEG) based emotion recognition commonly uses graph neural networks (GNNs) on full-channel signals.
    • Existing methods often overlook detailed interactions within and between brain regions, limiting representational power.

    Purpose of the Study:

    • To propose an explainable cross-level topological network (ECTN) for enhanced EEG emotion recognition.
    • To investigate and capture functional brain interactions from both channel-level and region-level perspectives.

    Main Methods:

    • Developed the ECTN framework with three modules: cross-region topological feature fusion, specific-region position-guided attention, and bidirectional gated fusion.
    • Decoupled EEG functional interactions into global region interactions and local region dynamics.

    Published on: July 31, 2016

  • Integrated channel-level and region-level features using the bidirectional gated fusion module, considering inclusion relationships.

    • Main Results:

    • The ECTN model demonstrated superior performance on the SEED, SEED-IV, and SEED-V datasets.
    • Experimental results validated the effectiveness of exploring both channel-wise and region-wise interactions for emotion recognition.

    Conclusions:

    • The proposed ECTN advances EEG emotion recognition by effectively modeling cross-level brain interactions.
    • Capturing both global and local brain dynamics significantly improves recognition accuracy.
