Sharp condition for supercritical Galton-Watson processes with countable types
Mathilde André, Jean-Jil Duchamps
We investigate Kesten-Stigum-like results for multi-type Galton-Watson processes with a countable number of types in a general setting, allowing us in particular to consider proces…
A functional central limit theorem for kernel gradient flow and infinitesimal gradient boosting
Clément Dombry, Jean-Jil Duchamps
Building on the large-sample analysis of infinitesimal gradient boosting (Dombry and Duchamps, 2024b), we study the fluctuations of the process around its deterministic limit and e…
A parameterized family of balance indices for phylogenetic networks
François Bienvenu, Jean-Jil Duchamps, Hadrien Maffioli
We introduce a new family of balance indices for phylogenetic networks: the indices, where is a positive real number. This family includes the index as a special…
The index of galled trees
François Bienvenu, Jean-Jil Duchamps, Michael Fuchs +1
In recent years, there has been an effort to extend the classical notion of phylogenetic balance, originally defined in the context of trees, to networks. One of the most natural w…
An RKHS Perspective on Tree Ensembles
Mehdi Dagdoug, Clement Dombry, Jean-Jil Duchamps
Random Forests and Gradient Boosting are among the most effective algorithms for supervised learning on tabular data. Both belong to the class of tree-based ensemble methods, where…
