L2 Boosting on generalized Hoeffding decomposition for dependent variables. Application to Sensitivity Analysis
Magali Champion, Gaëlle Chastaing, Sébastien Gadat +1
This paper is dedicated to the study of an estimator of the generalized Hoeffding decomposition. We build such an estimator using an empirical Gram-Schmidt approach and derive a co…
Informational Confidence Bounds for Self-Normalized Averages and Applications
Aurélien Garivier
We present deviation bounds for self-normalized averages and applications to estimation with a random number of observations. The results rely on a peeling argument in exponential…
Noisy classification with boundary assumptions
Sébastien Loustau, Clément Marteau
We address the problem of classification when data are collected from two samples with measurement errors. This problem turns to be an inverse problem and requires a specific treat…
A proportional hazard model for the estimation of ionosphere storm occurrence risk
Malika Chassan, Jean-Marc Azaïs, Guillaume Buscarlet +1
Severe Ionosphere magnetic storms are feared events for integrity and continuity of navigation systems such as EGNOS, the European SBAS (Satellite-Based Augmentation System) comple…
General regularization schemes for signal detection in inverse problems
Clément Marteau, Peter Mathé
The authors discuss how general regularization schemes, in particular linear regularization schemes and projection schemes, can be used to design tests for signal detection in stat…
Reliability sensitivity analysis based on probability distribution perturbation with application to CO2 storage
Ekaterina Sergienko, Paul Lemaître, Aurélie Arnaud +2
The objective of reliability sensitivity analysis is to determine input variables that mostly contribute to the variability of the failure probability. In this paper, we study a re…
