Differentially Private Vertical Federated Clustering
Summary: Practical DP vertical‑federated k‑means with an untrusted server: parties send DP local centers and DP membership encodings; server builds a weighted grid synopsis and runs k‑means. Novel DP set‑intersection via Flajolet‑Martin and refined weight estimation yield provable utility and lower loss than baselines. (summarized by gpt-5-mini on Feb 09 2026)
