Area of Science:

Neuroscience
Computer Science
Signal Processing

Background:

Emotion recognition is crucial for brain-computer interfaces and human-computer interaction.
Electroencephalography (EEG) is a key physiological signal for affective computing due to its temporal resolution and non-invasive nature.
EEG signals present challenges in emotion recognition due to noise and variability.

Purpose of the Study:

To develop a novel framework for accurate EEG-based emotion recognition.
To address the complexities and noise inherent in EEG signals.
To enhance the performance of emotion assessment systems using advanced deep learning techniques.

Main Methods:

Proposed a Triple Attention Network (TANet) integrating Conformer, Convolutional Block Attention Module (CBAM), and Mutual Cross-Modal Attention (MCA).
Conformer captures temporal dependencies, CBAM refines spatial features, and MCA fuses differential entropy and power spectral density.
Evaluated TANet on DEAP and SEED EEG emotion datasets.

Main Results:

TANet achieved 98.51% accuracy on the SEED dataset using subject-specific cross-validation.
On the DEAP dataset, TANet reached 99.69% for valence and 99.67% for arousal using segment-level splitting.
Demonstrated superior performance compared to existing methods, highlighting the complementary effects of attention mechanisms.

Conclusions:

TANet offers a high-performance, robust solution for EEG emotion recognition.
Provides theoretical insights into multi-dimensional attention for physiological signal processing.
Offers practical guidance for developing advanced EEG-based emotion assessment systems.
