Researchers have developed BioKD, a novel framework for emotion recognition that uses physiological signals to train a video-based model. This method addresses the limitations of relying solely on video cues, which can be ambiguous, and the impracticality of using physiological signals directly during inference. BioKD employs a reliability-aware gating mechanism to manage the noisy and unstable nature of physiological data, ensuring stable cross-modal distillation by adaptively controlling knowledge transfer. Experiments on the DEAP and AMIGOS datasets demonstrated BioKD's superior performance in valence and arousal recognition, particularly in subject-independent evaluations. AI
IMPACT This framework could improve the accuracy and applicability of emotion recognition systems by leveraging physiological data during training without requiring it at inference.
