Relaxed Models for Adversarial Streaming: The Advice Model and the Bounded Interruptions Model

no code implementations22 Jan 2023 Menachem Sadigurschi, Moshe Shechner, Uri Stemmer

Streaming algorithms are typically analyzed in the oblivious setting, where we assume that the input stream is fixed in advance.

On the Robustness of CountSketch to Adaptive Inputs

no code implementations28 Feb 2022 Edith Cohen, Xin Lyu, Jelani Nelson, Tamás Sarlós, Moshe Shechner, Uri Stemmer

CountSketch is a popular dimensionality reduction technique that maps vectors to a lower dimension using randomized linear measurements.

A Framework for Adversarial Streaming via Differential Privacy and Difference Estimators

no code implementations30 Jul 2021 Idan Attias, Edith Cohen, Moshe Shechner, Uri Stemmer

Classical streaming algorithms operate under the (not always reasonable) assumption that the input stream is fixed in advance.

Differentially Private Algorithms for Clustering with Stability Assumptions

no code implementations11 Jun 2021 Moshe Shechner

We study the problem of differentially private clustering under input-stability assumptions.
