MuDD: A Multimodal Deception Detection Dataset and GSR-Guided Progressive Distillation for Non-Contact Deception Detection

Researchers at Nemati AI have developed MuDD, a large-scale dataset for multimodal deception detection, which includes recordings from 130 participants across various physiological signals like GSR and video-audio data. They also introduced GSR-guided Progressive Distillation (GPD), a framework that enhances non-contact deception detection by leveraging stable patterns in GSR to guide representation learning in other modalities, significantly improving performance over existing methods. This advancement is crucial for developers working on automatic deception detection systems, as it provides a robust dataset and an effective training method to handle modality mismatches.
