    Summary

    This study introduces a novel deep learning model, the three-dimension convolution attention neural network (3DCANN), for accurate emotion recognition from electroencephalogram (EEG) signals. The 3DCANN model demonstrates superior performance compared to existing methods in classifying emotional states using EEG data.

    Main Methods:

    • Developed the 3DCANN model comprising spatio-temporal feature extraction and EEG channel attention weight learning modules.
    • Extracted dynamic relationships among multi-channel EEG signals and internal spatial relations.
    • Fused spatio-temporal features with dual attention learning weights for classification.
    • Utilized the SJTU Emotion EEG Dataset (SEED) for validation.

    Main Results:

    • The 3DCANN model effectively extracts spatio-temporal features and channel attention weights.
    • Experimental results on the SEED dataset show the model's feasibility and effectiveness.
    • The proposed 3DCANN method achieved superior performance over state-of-the-art models.
