Background:

Emotion recognition using electroencephalogram (EEG) signals is crucial for applications like diagnosing depression and developing brain-computer interfaces.
Current methods require precise and efficient emotion recognition for optimal performance.

Purpose of the Study:

To introduce a novel approach for emotion recognition using multi-scale EEG features, named the Dynamic Spatial-Spectral-Temporal Network (DSSTNet).
To improve the performance and channel selection efficiency in EEG-based emotion recognition.

Main Methods:

DSSTNet employs a spatial feature extractor using graph convolutional networks (GCN) to optimize channel relationships.
A band attention module extracts frequency information, followed by a temporal feature extractor for deep temporal insights.
A L2,1-norm regularization term is incorporated to promote sparse adjacency matrices, aiding in valid channel selection and noise reduction.

Main Results:

DSSTNet demonstrated superior performance in emotion recognition tasks on both a self-constructed (TJU-EmoEEG) and a public (SEED) dataset.
The method effectively identified and preserved emotionally relevant channels while filtering out noise from irrelevant ones.

Conclusions:

DSSTNet represents a significant advancement in EEG-based emotion recognition.
The proposed network architecture and regularization technique outperform current state-of-the-art methods, offering enhanced accuracy and efficiency.
