Spatio-temporal point process intensity estimation using zero-deflated subsampling applied to a lightning strikes dataset in France
Jean-François Coeurjolly, Thibault Espinasse, Anne-Laure Fougères +1
Cloud-to-ground lightning strikes observed in a specific geographical domain over time can be naturally modeled by a spatio-temporal point process. Our focus lies in the parametric…
A Probabilistic Graph Coupling View of Dimension Reduction
Hugues Van Assel, Thibault Espinasse, Julien Chiquet +1
Most popular dimension reduction (DR) methods like t-SNE and UMAP are based on minimizing a cost between input and latent pairwise similarities. Though widely used, these approache…
A coupling of the spectral measures at a vertex
Thibault Espinasse, Paul Rochet
Given the adjacency matrix of an undirected graph, we define a coupling of the spectral measures at the vertices, whose moments count the rooted closed paths in the graph. The resu…
Inferring gene regulatory networks from single-cell data: a mechanistic approach
Ulysse Herbach, Arnaud Bonnaffoux, Thibault Espinasse +1
The recent development of single-cell transcriptomics has enabled gene expression to be measured in individual cells instead of being population-averaged. Despite this considerable…
Reconstructing undirected graphs from eigenspaces
Yohann De Castro, Thibault Espinasse, Paul Rochet
In this paper, we aim at recovering an undirected weighted graph of vertices from the knowledge of a perturbed version of the eigenspaces of its adjacency matrix . For insta…
Relations between connected and self-avoiding walks in a digraph
Thibault Espinasse, Paul Rochet
Walks in a directed graph can be given a partially ordered structure that extends to possibly unconnected objects, called hikes. Studying the incidence algebra on this poset reveal…
