On the privacy cost for dependent Gaussian data: spectral density estimation under local differential privacy
Yann Issartel, François Roueff
We study the fundamental problem of estimating the dependence structure of a centered stationary Gaussian process under local differential privacy (LDP). In this setting, the spect…
Active Seriation: Efficient Ordering Recovery with Statistical Guarantees
James Cheshire, Yann Issartel
Active seriation aims at recovering an unknown ordering of items by adaptively querying pairwise similarities. The observations are noisy measurements of entries of an underlyi…
Minimax optimal seriation in polynomial time
Yann Issartel, Christophe Giraud, Nicolas Verzelen
We consider the seriation problem, whose goal is to recover a hidden ordering from a noisy observation of a permuted Robinson matrix. We establish sharp minimax rates under average…
Localization in 1D non-parametric latent space models from pairwise affinities
Christophe Giraud, Yann Issartel, Nicolas Verzelen
We consider the problem of estimating latent positions in a one-dimensional torus from pairwise affinities. The observed affinity between a pair of items is modeled as a noisy obse…
Locally differentially private estimation of nonlinear functionals of discrete distributions
Cristina Butucea, Yann Issartel
We study the problem of estimating non-linear functionals of discrete distributions in the context of local differential privacy. The initial data are supp…
On the Estimation of Network Complexity: Dimension of Graphons
Yann Issartel
Network complexity has been studied for over half a century and has found a wide range of applications. Many methods have been developed to characterize and estimate the complexity…
Pair-Matching: Links Prediction with Adaptive Queries
Christophe Giraud, Yann Issartel, Luc Lehéricy +1
The pair-matching problem appears in many applications where one wants to discover good matches between pairs of entities or individuals. Formally, the set of individuals is repres…
