Multi-epoch matrix factorization mechanisms for private machine learning

CA Choquette-Choo, HB McMahan, K Rush… - arXiv preprint arXiv …, 2022 - arxiv.org
We introduce new differentially private (DP) mechanisms for gradient-based machine
learning (ML) with multiple passes (epochs) over a dataset, substantially improving the …

Constant matters: Fine-grained error bound on differentially private continual observation

H Fichtenberger, M Henzinger… - … on Machine Learning, 2023 - proceedings.mlr.press
We study fine-grained error bounds for differentially private algorithms for counting under
continual observation. Our main insight is that the matrix mechanism when using lower …

A unifying framework for differentially private sums under continual observation

M Henzinger, J Upadhyay, S Upadhyay - … of the 2024 Annual ACM-SIAM …, 2024 - SIAM
We study the problem of maintaining a differentially private decaying sum under continual
observation. We give a unifying framework and an efficient algorithm for this problem for any …

A smooth binary mechanism for efficient private continual observation

JD Andersson, R Pagh - Advances in Neural Information …, 2024 - proceedings.neurips.cc
In privacy under continual observation we study how to release differentially private
estimates based on a dataset that evolves over time. The problem of releasing private prefix …

Continual observation under user-level differential privacy

W Dong, Q Luo, K Yi - 2023 IEEE Symposium on Security and …, 2023 - ieeexplore.ieee.org
In the foundational work of Dwork et al.[15] on continual observation under differential
privacy (DP), two privacy models have been proposed: event-level DP and user-level DP …

Efficient and near-optimal noise generation for streaming differential privacy

HB McMahan, K Pillutla, T Steinke… - arXiv preprint arXiv …, 2024 - arxiv.org
In the task of differentially private (DP) continual counting, we receive a stream of increments
and our goal is to output an approximate running total of these increments, without revealing …

The discrepancy of shortest paths

G Bodwin, C Deng, J Gao, G Hoppenworth… - arXiv preprint arXiv …, 2024 - arxiv.org
The hereditary discrepancy of a set system is a certain quantitative measure of the
pseudorandom properties of the system. Roughly, hereditary discrepancy measures how …

Concurrent shuffle differential privacy under continual observation

J Tenenbaum, H Kaplan, Y Mansour… - International …, 2023 - proceedings.mlr.press
We introduce the concurrent shuffle model of differential privacy. In this model we have
multiple concurrent shufflers permuting messages from different, possibly overlapping …

On differentially private counting on trees

B Ghazi, P Kamath, R Kumar, P Manurangsi… - arXiv preprint arXiv …, 2022 - arxiv.org
We study the problem of performing counting queries at different levels in hierarchical
structures while preserving individuals' privacy. Motivated by applications, we propose a …

Continual Observation of Joins under Differential Privacy

W Dong, Z Chen, Q Luo, E Shi, K Yi - … of the ACM on Management of …, 2024 - dl.acm.org
The problem of continual observation under differential privacy has been studied extensively
in the literature. However, all existing works, with the exception of [28, 51], have only studied …
