Latency-Optimal Geo-Distributed Storage over Structured Networks
Madhura Pathegama, Viveck Cadambe
We study latency-optimal file assignment in geo-distributed storage systems modeled as weighted graphs, where edge weights represent communication delays and each node stores one (…
Optimal Domain-Aware Privacy Mechanisms for Synthetic Data Generation
Sajani Vithana, Sangwon Jung, Haoyang Hu +3
Differential privacy (DP) imposes fundamental trade-offs between privacy and statistical fidelity in synthetic data generation. While access to public data has been shown to improv…
Local Differential Privacy with Correlated Noise Achieves Central-DP Optimal Cost
Madhura Pathegama, Srikanth Avasarala, Viveck R. Cadambe +1
We study privately estimating the sum of user-held values in the presence of an honest-but-curious server. This motivates requiring privacy not only at data release but also th…
Differentially Private Secure Multiplication: Beyond Two Multiplicands
Haoyang Hu, Viveck R. Cadambe
We study the problem of differentially private (DP) secure multiplication in distributed computing systems, focusing on regimes where perfect privacy and perfect accuracy cannot be…
Differentially Private Secure Multiplication with Erasures and Adversaries
Haoyang Hu, Viveck R. Cadambe
We consider a private distributed multiplication problem involving N computation nodes and T colluding nodes. Shamir's secret sharing algorithm provides perfect information-theoret…
Game of Coding: Sybil Resistant Decentralized Machine Learning with Minimal Trust Assumption
Hanzaleh Akbari Nodehi, Viveck R. Cadambe, Mohammad Ali Maddah-Ali
Coding theory plays a crucial role in ensuring data integrity and reliability across various domains, from communication to computation and storage systems. However, its reliance o…
