How ACLNet Boosts Skeleton-Based Action Recognition with Affinity Contrastive Learning
ACLNet, an Affinity Contrastive Learning Network introduced by researchers from the Chinese Academy of Sciences, BUPT and Moonshot AI, tackles the ambiguity of skeleton‑based human activity recognition by modeling inter‑class structural similarities and intra‑class margins, achieving state‑of‑the‑art results on NTU‑RGB+D, Kinetics‑Skeleton, FineGYM and other benchmarks.
