The Target-Charging Technique for Privacy Accounting across Interactive Computations

Edith Cohen, Xin Lyu

We propose the \emph{Target Charging Technique} (TCT), a unified privacy analysis framework for interactive settings where a sensitive dataset is accessed multiple times using diff…

Õptimal Differentially Private Learning of Thresholds and Quasi-Concave Optimization

Edith Cohen, Xin Lyu, Jelani Nelson +2

The problem of learning threshold functions is a fundamental one in machine learning. Classical learning theory implies sample complexity of (for generalizati…

Generalized Private Selection and Testing with High Confidence

Edith Cohen, Xin Lyu, Jelani Nelson +2

Composition theorems are general and powerful tools that facilitate privacy accounting across multiple data accesses from per-access privacy bounds. However they often result in we…

On the Robustness of CountSketch to Adaptive Inputs

Edith Cohen, Xin Lyu, Jelani Nelson +3

CountSketch is a popular dimensionality reduction technique that maps vectors to a lower dimension using randomized linear measurements. The sketch supports recovering -hea…

FriendlyCore: Practical Differentially Private Aggregation

Eliad Tsfadia, Edith Cohen, Haim Kaplan +2

Differentially private algorithms for common metric aggregation tasks, such as clustering or averaging, often have limited practicality due to their complexity or to the large numb…

A Framework for Adversarial Streaming via Differential Privacy and Difference Estimators

Idan Attias, Edith Cohen, Moshe Shechner +1

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 ro…
