Binned Group Algebra Factorization for Differentially Private Continual Counting

Monika Henzinger, Nikita P. Kalinin, Jalaj Upadhyay

We study memory-efficient matrix factorization for differentially private counting under continual observation. While recent work by Henzinger and Upadhyay 2024 introduced a factor…

A Generalized Binary Tree Mechanism for Differentially Private Approximation of All-Pair Distances

Michael Dinitz, Chenglin Fan, Jingcheng Liu +2

We study the problem of approximating all-pair distances in a weighted undirected graph with differential privacy, introduced by Sealfon [Sea16]. Given a publicly known undirected…
