Researchers have introduced GenPrior, a novel framework designed to improve zero-shot skeleton-based action recognition by leveraging generative priors from pre-trained Text-to-Motion (T2M) models. This approach addresses the semantic-kinematic gap in existing methods by distilling kinematic prototypes and intra-class dispersion from generated motion sequences. GenPrior utilizes a gating network to integrate structural cues from motion data while mitigating synthetic artifacts, and refines class prototypes by mining high-confidence unseen samples. Experiments on benchmark datasets like NTU-60, NTU-120, and PKU-MMD show that GenPrior achieves state-of-the-art results in both zero-shot and generalized zero-shot settings. AI
