Optimal Utility-Privacy Trade-off with Total Variation Distance as a Privacy Measure

2018 · arXiv (Cornell University)

The total variation distance is proposed as a privacy measure in an information disclosure scenario when the goal is to reveal some information about available data in order to receive utility, while preserving the privacy …

Distributed Learning in Wireless Networks: Recent Progress and Future Challenges

2021 · arXiv (Cornell University)

The next-generation of wireless networks will enable many machine learning (ML) tools and applications to efficiently analyze various types of data collected by edge devices for inference, autonomy, and decision making purposes. However, due to …

Effective Communications: A Joint Learning and Communication Framework\n for Multi-Agent Reinforcement Learning over Noisy Channels

2021 · arXiv (Cornell University)

We propose a novel formulation of the "effectiveness problem" in\ncommunications, put forth by Shannon and Weaver in their seminal work [2], by\nconsidering multiple agents communicating over a noisy channel in order to\nachieve better coordination and …

Quantifying and Localizing Usable Information Leakage from Neural Network Gradients

2021 · arXiv (Cornell University)

In collaborative learning, clients keep their data private and communicate only the computed gradients of the deep neural network being trained on their local data. Several recent attacks show that one can still extract private …

Private Variable-Length Coding with Zero Leakage

2023 · arXiv (Cornell University)

A private compression design problem is studied, where an encoder observes useful data $Y$, wishes to compress it using variable length code and communicates it through an unsecured channel. Since $Y$ is correlated with private …

Implicit Communication in Linear Quadratic Gaussian Control Systems

2025 · arXiv (Cornell University)

This paper studies implicit communication in linear quadratic Gaussian control systems. We show that the control system itself can serve as an implicit communication channel, enabling the controller to transmit messages through its inputs to …
