The author proposes the DPOD framework to address the challenge of detecting fake news using out-of-context images by leveraging domain-specific prompt tuning and out-of-domain data.
Sammendrag
The spread of fake news through out-of-context images is a significant issue in today's information overload era. The DPOD framework aims to improve multimodal fake news detection by aligning image-text pairs, creating semantic domain vectors, and utilizing domain-specific prompts. By leveraging out-of-domain data, the proposed framework achieves state-of-the-art performance on a benchmark dataset.
Key points:
- Fake news dissemination with out-of-context images is a prevalent problem.
- DPOD addresses this challenge by aligning image-text pairs and creating semantic domain vectors.
- The framework utilizes domain-specific prompts and out-of-domain data for improved detection.
- Extensive experiments show that DPOD outperforms existing approaches in detecting fake news.
- The model generalizes well to unseen domains and handles inconsistencies in domain labels effectively.
