Unleashing Multimodal Large Language Models for Training-free HOI Detection in the Wild

Two key mechanisms are introduced: Context-aware Multi-round Reasoning, which progressively refines interaction hypotheses to ensure exhaustive and compositional HOI discovery, and Multifaceted Interaction Localization, which enhances grounding precision by generating instance-specific descriptions that integrate seman...

Explainable Deepfake Detection with Feature-robust Augmentation and Evidence-grounded Explanation Optimization

Feature-robust Augmentation is introduced, which comprises diversified degradation-aware augmentation strategies, and a supervised contrastive learning pattern paired with a mean-teacher architecture that stabilizes features against augmentations through consistency constraints that wins the first place in ACM Multimed...
