The price of differential privacy under continual observation

P Jain, S Raskhodnikova… - … on Machine Learning, 2023 - proceedings.mlr.press
We study the accuracy of differentially private mechanisms in the continual release model. A
continual release mechanism receives a sensitive dataset as a stream of $ T $ inputs and …

A framework for adversarially robust streaming algorithms

O Ben-Eliezer, R Jayaram, DP Woodruff… - ACM Journal of the ACM …, 2022 - dl.acm.org
We investigate the adversarial robustness of streaming algorithms. In this context, an
algorithm is considered robust if its performance guarantees hold even if the stream is …

Tight bounds for adversarially robust streams and sliding windows via difference estimators

DP Woodruff, S Zhou - 2021 IEEE 62nd Annual Symposium on …, 2022 - ieeexplore.ieee.org
In the adversarially robust streaming model, a stream of elements is presented to an
algorithm and is allowed to depend on the output of the algorithm at earlier times during the …

Adversarial laws of large numbers and optimal regret in online classification

N Alon, O Ben-Eliezer, Y Dagan, S Moran… - Proceedings of the 53rd …, 2021 - dl.acm.org
Laws of large numbers guarantee that given a large enough sample from some population,
the measure of any fixed sub-population is well-estimated by its frequency in the sample. We …

Dynamic algorithms against an adaptive adversary: generic constructions and lower bounds

A Beimel, H Kaplan, Y Mansour, K Nissim… - Proceedings of the 54th …, 2022 - dl.acm.org
Given an input that undergoes a sequence of updates, a dynamic algorithm maintains a
valid solution to some predefined problem at any point in time; the goal is to design an …

Adversarial robustness of streaming algorithms through importance sampling

V Braverman, A Hassidim, Y Matias… - Advances in …, 2021 - proceedings.neurips.cc
Robustness against adversarial attacks has recently been at the forefront of algorithmic
design for machine learning tasks. In the adversarial streaming model, an adversary gives …

A framework for adversarial streaming via differential privacy and difference estimators

I Attias, E Cohen, M Shechner, U Stemmer - Algorithmica, 2024 - Springer
Classical streaming algorithms operate under the (not always reasonable) assumption that
the input stream is fixed in advance. Recently, there is a growing interest in designing robust …

The white-box adversarial data stream model

M Ajtai, V Braverman, TS Jayram, S Silwal… - Proceedings of the 41st …, 2022 - dl.acm.org
There has been a flurry of recent literature studying streaming algorithms for which the input
stream is chosen adaptively by a black-box adversary who observes the output of the …

Adversarially robust coloring for graph streams

A Chakrabarti, P Ghosh, M Stoeckl - arXiv preprint arXiv:2109.11130, 2021 - arxiv.org
A streaming algorithm is considered to be adversarially robust if it provides correct outputs
with high probability even when the stream updates are chosen by an adversary who may …

Adversarially Robust Streaming via Dense-Sparse Trade-offs∗

O Ben-Eliezer, T Eden, K Onak - Symposium on Simplicity in Algorithms …, 2022 - SIAM
A streaming algorithm is adversarially robust if it is guaranteed to perform correctly even in
the presence of an adaptive adversary. The development and analysis of such algorithms …
