Exact Privacy--Distortion Design of Support-Constrained Randomized Response

Amirreza Zamani, Parastoo Sadeghi, Mikael Skoglund

Full-support local randomizers can incur unnecessary reporting distortion on ordered alphabets. We study randomized response whose output is restricted to a radius- neighborhood…

Residual-Information Generalization Bounds Under Selective Privacy: Extended Version

Amirreza Zamani, Parastoo Sadeghi, Mikael Skoglund

Information-theoretic generalization bounds usually control dependence on the task sample, whereas selective privacy may constrain only a different, private coordinate. We study i.…

Sparse Kernel Mechanisms for Locally Differentially Private Discrete Channels

Amirreza Zamani, Parastoo Sadeghi, Mikael Skoglund

We study sparse locally private discrete mechanisms generated by a nonnegative kernel and an input-dependent admissible output support. The support set is intentionally small relat…

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 Özgür, 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 Özgür, 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…

Information-Theoretic Fairness with A Bounded Statistical Parity Constraint

Amirreza Zamani, Abolfazl Changizi, Ragnar Thobaben +1

In this paper, we study an information-theoretic problem of designing a fair representation that attains bounded statistical (demographic) parity. More specifically, an agent uses…
