HYDRA: Large-scale Social Identity Linkage via Heterogeneous Behavior Modeling
Summary: HYDRA links identities across platforms via heterogeneous-behavior modeling, a structural-consistency graph on core networks, and joint optimization of supervised linkage with cross-platform coherence. Scale: 10M users, 7 networks; gains >=20% over SOTA, up to 4x in settings. (summarized by gpt-5-nano on Feb 09 2026)
