Key Innovations
- Novel three-dimensional multimodal fusion framework for comprehensive feature representation.
- Advanced ViLBERT-Multi-Task model for intricate cross-modal relationship capture.
- Effective class imbalance handling using SMOTE, preventing model bias.
- Superior performance validated through extensive empirical evaluation.
Actionable Recommendations
- Implement the proposed 3D multimodal fusion framework to enhance existing fake news detection systems, focusing on integrating social context features to capture subtle deception cues missed by unimodal or dual-modal approaches.
- Prioritize SVM for initial deployment due to its proven robustness on high-dimensional and imbalanced social media datasets. Concurrently, invest in larger, more diverse datasets to unlock the full potential of advanced deep learning models like FNN and CNN-1D.
- Develop targeted solutions for persistent challenges such as text-dominant visual content (memes), linguistic ambiguity (sarcasm/irony), and class imbalance by exploring hybrid datasets, advanced OCR, and pragmatics-aware architectures.
- Establish rigorous validation protocols including bias mitigation frameworks (e.g., Fairlearn) and ongoing adversarial testing (e.g., MisinfoChallenge) to ensure ethical AI deployment and protect against evolving misinformation tactics.
- Integrate explainability frameworks (e.g., SHAP) and human oversight mechanisms to foster transparent decision-making, maintain accountability, and build user trust in the AI-powered detection system.
