Area of Science:

Neuroscience
Computer Science
Human-Computer Interaction

Background:

Meaningful human-computer interaction relies on emotion recognition.
Advancements in wearable electroencephalography (EEG) devices have increased demand for emotion identification.
Current scientific knowledge on EEG-based emotion recognition remains limited.

Purpose of the Study:

To introduce a novel EEG-based emotion recognition framework.
To address the limitations in current EEG-based emotion recognition research.
To improve the accuracy and efficiency of emotion identification from EEG signals.

Main Methods:

The framework includes preprocessing, feature extraction, feature selection, and classification stages.
Preprocessing utilizes multi-scale principle component analysis and a symlets-4 filter.
Feature extraction employs dual-tree complex wavelet transform (DTCWT), followed by statistical criteria for feature selection.
Ensemble classifiers, specifically a random subspace ensemble classifier, are used for the final classification.

Main Results:

The proposed framework achieved an accuracy of nearly 96.8%.
The random subspace ensemble classifier demonstrated strong performance in the classification stage.
The framework effectively processes EEG signals for emotion identification.

Conclusions:

The developed EEG-based framework performs effectively in emotion recognition.
The proposed methods offer a promising approach for advancing the field of affective computing.
High accuracy suggests the framework's potential for real-world applications.
