Stochastic approximation algorithms for superquantiles estimation
Bernard Bercu, Manon Costa, Sébastien Gadat
This paper is devoted to two different two-time-scale stochastic approximation algorithms for superquantile estimation. We shall investigate the asymptotic behavior of a Robbins-Mo…

Survival criterion for a population subject to selection and mutations ; Application to temporally piecewise constant environments
Manon Costa, Christèle Etchegaray, Sepideh Mirrahimi
We study a parabolic Lotka-Volterra type equation that describes the evolution of a population structured by a phenotypic trait, under the effects of mutations and competition for…

Cytometry inference through adaptive atomic deconvolution
Manon Costa, Sébastien Gadat, Pauline Gonnord +1
In this paper we consider a statistical estimation problem known as atomic deconvolution. Introduced in reliability, this model has a direct application when considering biological…
