Coefficientwise Hankel-total positivity of the Schett polynomials
Bishal Deb, Alan D. Sokal
We prove the coefficientwise Hankel-total positivity of the even and odd subsequences of Schett polynomials .
Non-linear non-zero-sum Dynkin games with Bermudan strategies
Miryana Grigorova, Marie-Claire Quenez, Yuan Peng
In this paper, we study a non-zero-sum game with two players, where each of the players plays what we call Bermudan strategies and optimizes a general non-linear assessment functio…
An updated State-of-the-Art Overview of transcriptomic Deconvolution Methods
Bastien Chassagnol, Grégory Nuel, Etienne Becht
Although bulk transcriptomic analyses have significantly contributed to an enhanced comprehension of multifaceted diseases, their exploration capacity is impeded by the heterogeneo…
Gradient COBRA: A kernel-based consensual aggregation for regression
Sothea Has
In this article, we introduce a kernel-based consensual aggregation method for regression problems. We aim to exibly combine individual regression estimators usi…
Structure of hyperbolic polynomial automorphisms of C^2 with disconnected Julia sets
Romain Dujardin, Mikhail Lyubich
For a hyperbolic polynomial automorphism of C^2 with a disconnected Julia set, and under a mild dissipativity condition, we give a topological description of the components of the…
A mixture of ellipsoidal densities for 3D data modelling
Denis Brazey, Antoine Godichon-Baggioni, Bruno Portier
In this paper, we propose a new ellipsoidal mixture model. This model is based a new probability density function belonging to the family of elliptical distributions and designed t…
