Labeling Emotion

848
Emotional labeling is a cognitive process that involves identifying and naming one's emotions, such as anger, fear, happiness, or sadness. It allows individuals to recognize and express their internal emotional states, a critical aspect of emotional regulation and communication. Labeling emotions requires more than mere recognition; it also involves drawing upon memory and contextual cues to understand the current situation and apply a corresponding emotional label. For instance, feeling...

    Summary
    This summary is machine-generated.

    This study introduces a new framework, the Sub-band Embedded Spatio-Temporal Network (SESTN), for more accurate emotion recognition from electroencephalogram (EEG) signals. SESTN enhances analysis by capturing multi-frequency spatial and temporal brain activity patterns.

    Area of Science:

    • Neuroscience
    • Artificial Intelligence
    • Biomedical Engineering

    Background:

    • Electroencephalogram (EEG)-based emotion recognition is vital for mental health and affective computing.
    • Existing Graph Neural Network (GNN) methods struggle with higher-order brain region associations and frequency-specific temporal learning in EEG signals.

    Purpose of the Study:

    • To develop a novel framework, the Sub-band Embedded Spatio-Temporal Network (SESTN), for improved EEG-based emotion recognition.
    • To jointly model multi-frequency spatial and temporal dependencies in EEG signals, overcoming limitations of prior GNN approaches.

    Main Methods:

    • EEG features are embedded into sub-band spaces for frequency-specific representation.
    • Neurophysiological priors are used to construct weighted hyperedges for intra-regional spatial relationships.
    • A Mamba-based temporal module extracts frequency-specific temporal dynamics, followed by graph convolutional fusion across frequency bands.

    Main Results:

    • The proposed SESTN framework significantly enhances EEG emotion recognition performance.
    • Improvements were observed in both subject-dependent and subject-independent classification scenarios on SEED and SEED-IV datasets.

    Conclusions:

    • SESTN offers a robust and effective approach for analyzing complex EEG spatio-temporal dynamics.
    • This framework shows significant potential for real-world applications in affective state monitoring and mental health assessment.
