Modern Structure-Aware Simplicial Spatiotemporal Neural Network
Zhaobo Hu, Vincent Gauthier, Mehdi Naima
Spatiotemporal modeling has evolved beyond simple time series analysis to become fundamental in structural time series analysis. While current research extensively employs graph ne…
Beyond the Laplacian: Doubly Stochastic Matrices for Graph Neural Networks
Zhaobo Hu, Vincent Gauthier, Mehdi Naima
Graph Neural Networks (GNNs) conventionally rely on standard Laplacian or adjacency matrices for structural message passing. In this work, we substitute the traditional Laplacian w…
Reversible Residual Normalization Alleviates Spatio-Temporal Distribution Shift
Zhaobo Hu, Vincent Gauthier, Mehdi Naima
Distribution shift severely degrades the performance of deep forecasting models. While this issue is well-studied for individual time series, it remains a significant challenge in…
The ascent lattice on Dyck paths
Jean-Luc Baril, Mireille Bousquet-Mélou, Sergey Kirgizov +1
In the Stanley lattice defined on Dyck paths of size , cover relations are obtained by replacing a valley by a peak . We investigate a greedy version of this lattice, f…
A lattice on Dyck paths close to the Tamari lattice
Jean-Luc Baril, Sergey Kirgizov, Mehdi Naima
We introduce a new poset structure on Dyck paths where the covering relation is a particular case of the relation inducing the Tamari lattice. We prove that the transitive closure…
Temporal Betweenness Centrality on Shortest Walks Variants
Mehdi Naima
Betweenness centrality has been extensively studied since its introduction in 1977 as a measure of node importance in graphs. This measure has found use in various applications and…
Temporal Betweenness Centrality on Shortest Paths
Mehdi Naima, Matthieu Latapy, Clémence Magnien
Betweenness centrality measure assesses the importance of nodes in a graph and has been used in a variety of contexts. Betweenness centrality has also been extended to temporal gra…
Compaction for two models of logarithmic-depth trees: Analysis and Experiments
Olivier Bodini, Antoine Genitrini, Bernhard Gittenberger +2
We are interested in the quantitative analysis of the compaction ratio for two classical families of trees: recursive trees and plane binary increasing trees. These families are ty…
Ranked Schröder Trees
Olivier Bodini, Antoine Genitrini, Mehdi Naima
In biology, a phylogenetic tree is a tool to represent the evolutionary relationship between species. Unfortunately, the classical Schröder tree model is not adapted to take into a…
