ProMoDD: Dataset Distillation for 3D Human Motion via Prototype-Conditioned Diffusion Models

Dataset distillation (DD) aims to retain the training utility of a large dataset in a much smaller set of examples. For skeleton-based action recognition, this requires capturing discriminative motion variation without disrupting the geometry and temporal continuity of articulated bodies. Directly optimizing joint coor...

Dataset Distillation Based on Saliency-Driven Prototype Alignment

This work proposes a saliency-driven distillation framework that constructs class-discriminative latent prototypes to enhance representativeness and generalization and demonstrates consistent performance improvements over strong baselines.
