Idempotent Unsupervised Representation Learning for Skeleton-Based Action Recognition

ECCV 2024poster

"Generative models, as a powerful technique for generation, also gradually become a critical tool for recognition tasks. However, in skeleton-based action recognition, the features obtained from existing pre-trained generative methods contain redundant information unrelated to recognition, which con…

MacDiff: Unified Skeleton Modeling with Masked Conditional Diffusion

ECCV 2024poster

"Self-supervised learning has proved effective for skeleton-based human action understanding. However, previous works either rely on contrastive learning that suffers false negative problems or are based on reconstruction that learns too much unessential low-level clues, leading to limited represent…
