New methods improve change-point detection under local differential privacy

Researchers have developed new parametric methods for change-point detection under local differential privacy. The study derives improved accuracy guarantees for a generalized likelihood-ratio estimator and establishes finite-sample minimax lower bounds in both private and non-private settings. Algorithms were designed based on aggregated randomized response and binary mechanisms to maximize Chernoff information, with their performance evaluated on synthetic data. AI

IMPACT This research could lead to more robust and privacy-preserving methods for analyzing sequential data in AI systems.

    Locally Private Parametric Methods for Change-Point Detection

    arXiv:2602.13619v2 Announce Type: replace Abstract: We study parametric change-point detection under local differential privacy, focusing on the offline localization of a single change point in a sequence of independent observations.~In the non-private setting, we derive improved…
