Our Hybrid Deep Learning Framework for FER

The proposed framework integrates ResNet-50, the Convolutional Block Attention Module (CBAM), 3D Convolutional Neural Networks (3D CNN), and Ant Colony and Genetic Algorithm-based Target Optimization (AGTO) to deliver superior performance in real-time emotion detection.

ResNet-50 forms the robust backbone for deep feature extraction, addressing vanishing gradient problems in deep networks. CBAM enhances feature relevance by focusing on critical facial regions through spatial and channel attention mechanisms. 3D CNNs are crucial for capturing temporal dynamics of facial expressions over time, interpreting evolving emotional states.

Finally, AGTO fine-tunes the entire model's parameters and architecture, ensuring optimal performance and robustness in diverse online classroom environments. This multi-component approach addresses limitations of simpler models, making the system highly adaptable and precise.

Unmatched Performance and Rigorous Validation

Our proposed FER-AGTO system demonstrates superior accuracy and robustness across multiple challenging datasets, significantly outperforming existing methodologies. Ablation studies confirmed the synergistic effect of integrating ResNet-50, CBAM, 3D CNN, and AGTO, with each component critically contributing to the enhanced performance.

The system achieved 95.57% accuracy on FER2013, 97.29% on CK+, 98.35% on KDEF, and 98.09% on a proprietary dataset. These results highlight the model's ability to handle complex and dynamic facial expressions, making it highly reliable for real-time applications in online learning environments.

Computational efficiency analysis shows a favorable trade-off: while the hybrid system incurs slightly higher training and inference times, the substantial accuracy gains justify this overhead for applications requiring precise and reliable emotion detection.

Transforming Online Education with Real-time Engagement

The FER-AGTO framework has been rigorously tested in a real-world online learning environment, demonstrating its practical applicability and immense potential. By providing real-time insights into student emotional states, the system empowers educators to implement adaptive teaching strategies, tailor content, and offer timely interventions, fostering a more responsive and supportive educational environment.

This capability goes beyond mere performance metrics; it enables personalized learning experiences that recognize and respond to individual student needs, significantly enhancing learning outcomes and overall student well-being. The robust generalization across diverse datasets and dynamic conditions ensures its effectiveness in varied online classroom settings.
