A research paper from XInsight Lab details a novel framework for few-shot hidden emotion recognition in long videos, achieving first place in the 4th EI-MIGA-IJCAI Challenge. The approach utilizes a multi-modal temporal modeling framework incorporating various features like 2D/3D skeletons, facial expressions, and vision foundation models. A key innovation is a cross-attention mechanism that distinguishes static pose from dynamic micro-motion, mitigating individual biases. The paper also identifies and analyzes the phenomenon of representation collapse in general vision foundation models when applied to micro-dynamic tasks. AI
IMPACT Identifies representation collapse in vision models, potentially guiding future research in micro-dynamic tasks.
