Csiszár indices and interpolating copulas
Cristina Butucea, Jean-François Delmas, Anne Dutfoy +1
We study various properties of -divergences and Csiszár indices between two probability distributions in very general setups for the convex function and for the probability…
A tree-based Polynomial Chaos expansion for surrogate modeling and sensitivity analysis of complex numerical models
Faten Ben Said, Aurélien Alfonsi, Anne Dutfoy +4
This paper introduces Tree-based Polynomial Chaos Expansion (Tree-PCE), a novel surrogate modeling technique designed to efficiently approximate complex numerical models exhibiting…
Off-the-grid prediction and testing for linear combination of translated features
Cristina Butucea, Jean-François Delmas, Anne Dutfoy +1
We consider a model where a signal (discrete or continuous) is observed with an additive Gaussian noise process. The signal is issued from a linear combination of a finite but incr…
Simultaneous off-the-grid learning of mixtures issued from a continuous dictionary
Cristina Butucea, Jean-François Delmas, Anne Dutfoy +1
In this paper we observe a set, possibly a continuum, of signals corrupted by noise. Each signal is a finite mixture of an unknown number of features belonging to a continuous dict…
Adaptive importance sampling based on fault tree analysis for piecewise deterministic Markov process
Guillaume Chennetier, Hassane Chraibi, Anne Dutfoy +1
Piecewise deterministic Markov processes (PDMPs) can be used to model complex dynamical industrial systems. The counterpart of this modeling capability is their simulation cost, wh…
Reparameterization of extreme value framework for improved Bayesian workflow
Théo Moins, Julyan Arbel, Stéphane Girard +1
Using Bayesian methods for extreme value analysis offers an alternative to frequentist ones, with several advantages such as easily dealing with parametric uncertainty or studying…
