Label-Efficient Skeleton-based Recognition with Stable-Invertible Graph Convolutional Networks

arXiv — cs.CVMonday, November 24, 2025 at 5:00:00 AM
  • A novel method for skeleton-based action recognition has been introduced, utilizing graph convolutional networks (GCNs) to enhance label efficiency. This approach addresses the challenge of acquiring large, labeled datasets by scoring the most informative subsets for labeling, optimizing data representativity, diversity, and uncertainty. Extensive experiments demonstrate its effectiveness on challenging datasets.
  • This development is significant as it reduces the reliance on extensive manual labeling, which is often costly and time-consuming. By improving label efficiency, the method can accelerate advancements in action recognition technologies, potentially benefiting various applications in computer vision and artificial intelligence.
  • The introduction of this label-efficient method aligns with ongoing efforts in the AI field to tackle challenges such as class imbalance and data scarcity. Similar advancements in related areas, like long-tailed object detection and pose estimation, highlight a broader trend towards developing more efficient algorithms that require less data while maintaining high performance, reflecting a growing need for innovative solutions in machine learning.
