Chiaroscuro: Transparency and Privacy for Massive Personal Time-Series Clustering

Summary: Chiaroscuro proposes Diptych, a privacy-preserving method enabling encrypted, DP-based collaboration for time-series clustering. Distributed on-device execution tolerates churn, delivering high clustering quality with DP and validated on real/synthetic data. (summarized by gpt-5-nano on Feb 09 2026)
