Do More Modalities Always Help? A Geometric Perspective on Missing-Modality Robustness
Missing modality remains a longstanding challenge in multimodal learning. Existing methods typically address this issue through modality recovery or adaptive strategies. However, they overlook models'internal cross-modal dependencies formed during multimodal training, which later impair robustness. We systematically ch...
