Brain-computer interfaces (BCIs) hold promise for various applications, with emotion classification from electroencephalography (EEG) being a significant research focus. However, accurately classifying emotions from EEG data remains a challenge due to the complexity and individual variation of emotional signatures in the brain. This paper proposes a novel Hybrid Ensemble Stacking Model (HESM) with network analysis integration to enhance emotion classification accuracy using EEG signals. Our approach leverages a diverse set of base classifiers (Logistic Regression, Support Vector Machines, and a Multi- Layer Perceptron) in a stacking ensemble architecture with dynamic model selection by a meta-learner. Additionally, we utilize a specialized Convolutional Neural Network (CNN) tailored for extracting spatiotemporal EEG patterns relevant to emotions. To further improve our model's performance, we introduce network analysis techniques. We construct functional connectivity networks from EEG time series data using measures such as coherence and phase locking value. We then extract features like centrality measures, clustering coefficients, and path lengths, which capture the topological structure of brain networks associated with emotional states. These network features are integrated into the HESM alongside traditional EEG features, providing richer insights for classification. The proposed methodology is evaluated on an EEG dataset containing positive, negative, and neutral emotional states. We rigorously tune hyperparameters using grid search for both the HESM components and the CNN. Results demonstrate that our hybrid model, augmented with network analysis, leads to significantly improved emotion classification performance compared to standalone machine learning models and CNN-only approaches. Providing a high accuracy with less amount of runtime and reduces the risk of overfitting and is suitable for imbalanced data.This research highlights the potential of combining traditional machine learning, deep learning, and network analysis to decode complex emotional patterns from EEG data for robust BCI applications.
