Minimax Quantile Lower Bounds for Interactive Statistical Decision Making with Privacy
Raghav Bongole, Amirreza Zamani, Tobias J. Oechtering +1
Minimax risk and regret are expectation-based criteria and do not capture rare but consequential failures. To address this concern, we develop a -explicit minimax-quantile theo…
Sparse Discrete Laplace and Gaussian Mechanisms under Local Differential Privacy
Amirreza Zamani, Sajad Daei, Parastoo Sadeghi +1
We study sparse locally private channels of the form where the admissible output set is allowed to depend on the private input …
Sparse Point-wise Privacy Leakage: Mechanism Design and Fundamental Limits
Amirreza Zamani, Sajad Daei, Parastoo Sadeghi +1
We study an information-theoretic privacy mechanism design problem, where an agent observes useful data that is arbitrarily correlated with sensitive data , and design discl…
Privacy-Utility Trade-offs Under Multi-Level Point-Wise Leakage Constraints
Amirreza Zamani, Parastoo Sadeghi, Mikael Skoglund
An information-theoretic privacy mechanism design is studied, where an agent observes useful data which is correlated with the private data . The agent wants to reveal the i…
An Information Geometric Approach to Fairness With Equalized Odds Constraint
Amirreza Zamani, Ayfer Ãzgür, Mikael Skoglund
We study the statistical design of a fair mechanism that attains equalized odds, where an agent uses some useful data (database) to solve a task . Since both and are…
On Information Theoretic Fairness With A Bounded Point-Wise Statistical Parity Constraint: An Information Geometric Approach
Amirreza Zamani, Ayfer Ãzgür, Mikael Skoglund
In this paper, we study an information-theoretic problem of designing a fair representation under a bounded point-wise statistical (demographic) parity constraint. More specificall…
