The communication cost of security and privacy in federated frequency estimation
Wei-Ning Chen, Ayfer Özgür, Graham Cormode +1
We consider the federated frequency estimation problem, where each user holds a private item from a size- domain and a server aims to estimate the empirical frequency (i.e…
Pointwise Bounds for Distribution Estimation under Communication Constraints
Wei-Ning Chen, Peter Kairouz, Ayfer Özgür
We consider the problem of estimating a -dimensional discrete distribution from its samples observed under a -bit communication constraint. In contrast to most previous resul…
Fisher information under local differential privacy
Leighton Pate Barnes, Wei-Ning Chen, Ayfer Ozgur
We develop data processing inequalities that describe how Fisher information from statistical samples can scale with the privacy parameter under local differential pr…
Anonymous Heterogeneous Distributed Detection: Optimal Decision Rules, Error Exponents, and the Price of Anonymity
Wei-Ning Chen, I-Hsiang Wang
We explore the fundamental limits of heterogeneous distributed detection in an anonymous sensor network with n sensors and a single fusion center. The fusion center collects the si…
