Fast pick-freeze estimation of Sobol' sensitivity maps using basis expansions
Yuri Sao, Olivier Roustant, Geraldo de Freitas Maciel
Global sensitivity analysis (GSA) aims at quantifying the contribution of input variables over the variability of model outputs. In the frame of functional outputs, a common goal i…
Adaptive inference with random ellipsoids through Conformal Conditional Linear Expectation
Iain Henderson, Adrien Mazoyer, Fabrice Gamboa
We propose two new conformity scores for conformal prediction, in a general multivariate regression framework. The underlying score functions are based on a covariance analysis of…
Asymptotic efficiency for Sobol' and Cram{é}r-von Mises indices under two designs of experiments
Thierry Klein, Agnès Lagnoux, Paul Rochet +1
A variety of indices aim to quantify the impact of input variables on a response, typically the output from a complex computer code or black-box model. Most commonly used, the Sobo…
Asymptotic analysis for covariance parameter estimation of Gaussian processes with functional inputs
Lucas Reding, Andrés F. López-Lopera, François Bachoc
We consider covariance parameter estimation for Gaussian processes with functional inputs. From an increasing-domain asymptotics perspective, we prove the asymptotic consistency an…
Minimax density estimation in the adversarial framework under local differential privacy
Mélisande Albert, Juliette Chevallier, Béatrice Laurent +1
We consider the problem of nonparametric density estimation under privacy constraints in an adversarial framework. To this end, we study minimax rates over Sobolev spaces under loc…
