Phase transitions for support recovery under local differential privacy
Cristina Butucea, Amandine Dubois, Adrien Saumard
We address the problem of variable selection in a high-dimensional but sparse mean model, under the additional constraint that only privatised data are available for inference. The…
Locally private non-asymptotic testing of discrete distributions is faster using interactive mechanisms
Thomas B. Berrett, Cristina Butucea
We find separation rates for testing multinomial or more general discrete distributions under the constraint of local differential privacy. We construct efficient randomized algori…
Interactive versus non-interactive locally differentially private estimation: Two elbows for the quadratic functional
Cristina Butucea, Angelika Rohde, Lukas Steinberger
Local differential privacy has recently received increasing attention from the statistics community as a valuable tool to protect the privacy of individual data owners without the…
