New algorithms achieve optimal person-level differential privacy for discrete distributions

Researchers have developed new algorithms for learning discrete distributions while adhering to person-level differential privacy in a batched setting. The algorithms achieve near-optimal guarantees under both pure and approximate differential privacy, improving upon previous methods. A key innovation is a novel degree-6 sum-of-squares estimator that utilizes semidefinite programming and Grothendieck's inequality to ensure privacy. AI

IMPACT Advances theoretical understanding and practical methods for privacy-preserving machine learning, potentially enabling more sensitive data analysis.

    Efficient and Optimal Learning of Discrete Distributions with Person-Level Privacy

    We study learning a discrete distribution under person-level differential privacy in the batched setting. Given $n$ users, each contributing $m$ i.i.d. samples from an unknown distribution $μ$ over $[k]$, we seek an estimate of $μ$ with total-variation error $α$. We give polynomi…
