Preprint: Common Sense Reasoning for Deep Fake Detection

Summary

State-of-the-art approaches rely on image-based features extracted via neural networks for the deepfake detection binary classification. While these approaches trained in the supervised sense extract likely fake features, they may fall short in representing unnatural `non-physical' semantic facial attributes -- blurry hairlines, double eyebrows, rigid eye pupils, or unnatural skin shading. However, such facial attributes are generally easily perceived by humans via common sense reasoning. Furthermore, image-based feature extraction methods that provide visual explanation via saliency maps can be hard to be interpreted by humans. To address these challenges, we propose the use of common sense reasoning to model deepfake detection, and extend it to the Deepfake Detection VQA (DD-VQA) task with the aim to model human intuition in explaining the reason behind labeling an image as either real or fake. To this end, we introduce a new dataset that provides answers to the questions related to the authenticity of an image, along with its corresponding explanations. We also propose a Vision and Language Transformer-based framework for the DD-VQA task, incorporating text and image aware feature alignment formulations. Finally, we evaluate our method on both the performance of deepfake detection and the quality of the generated explanations. We hope that this task inspires researchers to explore new avenues for enhancing language-based interpretability and cross-modality applications in the realm of deepfake detection.
