Network-Wide Traffic Volume Estimation from Speed Profiles using a Spatio-Temporal Graph Neural Network with Directed Spatial Attention
Léo Hein, Giovanni de Nunzio, Giovanni Chierchia +2
Existing traffic volume estimation methods typically address either forecasting traffic on sensor-equipped roads or spatially imputing missing volumes using nearby sensors. While f…
Cool Pavements
Martin Hendel
Cool pavements designate alternative pavements designed to reduce their contribution to urban heating. Urban heating generally refers to the sensible heat exchanged with the atmosp…
Cartographie du confort thermique au sein d'une cours d'{é}cole parisienne : couplage de mesures microclimatiques fixes et mobiles
Ghid Karam, Maïlys Chanial, Maxime Chaumont +2
Climate change will result in more frequent, more intense and longer-lasting heat waves by 2050. As part of its Climate Plan and its resilience strategy, the City of Paris is deplo…
The Oasis Project: UHI mitigation strategies applied to Parisian schoolyards
Ghid Karam, Martin Hendel, Bobée Cécilia +3
Paris is experimenting and implementing strategies to increase the capital's resilience and promote climate change adaptation. Major heatwaves have been hitting the French Capital…
Physical and geographic analysis of the urban cooling potential
Martin Hendel, Parison Sophie, Royon Laurent
The performance of a number of urban cooling techniques has been thoroughly studied by the scientific community. However, decision-makers lack the tools to spatialize their deploym…
Thermal and microclimatic behavior of OASIS schoolyard paving materials
Ghid Karam, Maïlys Chanial, Arnaud Grados +2
As part of its Resilience Strategy, the City of Paris' OASIS program aims to contribute ot its adaptation to heatwaves and climate change by transforming schoolyards into climate s…
Improving Plasticity in Online Continual Learning via Collaborative Learning
Maorong Wang, Nicolas Michel, Ling Xiao +1
Online Continual Learning (CL) solves the problem of learning the ever-emerging new classification tasks from a continuous data stream. Unlike its offline counterpart, in online CL…
Silhouettes and generic properties of subgroups of the modular group
Frédérique Bassino, Cyril Nicaud, Pascal Weil
We show that the probability for a finitely generated subgroup of the modular group, of size , to be almost malnormal or non-parabolic, tends to 0 as tends to infinity -- wh…
Domain-Aware Augmentations for Unsupervised Online General Continual Learning
Nicolas Michel, Romain Negrel, Giovanni Chierchia +1
Continual Learning has been challenging, especially when dealing with unsupervised scenarios such as Unsupervised Online General Continual Learning (UOGCL), where the learning agen…
Learning Representations on the Unit Sphere: Investigating Angular Gaussian and von Mises-Fisher Distributions for Online Continual Learning
Nicolas Michel, Giovanni Chierchia, Romain Negrel +1
We use the maximum a posteriori estimation principle for learning representations distributed on the unit sphere. We propose to use the angular Gaussian distribution, which corresp…
Join, select, and insert: efficient out-of-core algorithms for hierarchical segmentation trees
Josselin Lefèvre, Jean Cousty, Benjamin Perret +1
Binary Partition Hierarchies (BPH) and minimum spanning trees are fundamental data structures involved in hierarchical analysis such as quasi-flat zones or watershed. However, clas…
Distributed coloring and the local structure of unit-disk graphs
Louis Esperet, Sébastien Julliot, Arnaud de Mesmay
Coloring unit-disk graphs efficiently is an important problem in the global and distributed setting, with applications in radio channel assignment problems when the communication r…
Triplet-Watershed for Hyperspectral Image Classification
Aditya Challa, Sravan Danda, B. S. Daya Sagar +1
Hyperspectral images (HSI) consist of rich spatial and spectral information, which can potentially be used for several applications. However, noise, band correlations and high dime…
Stochastic optimization with momentum: convergence, fluctuations, and traps avoidance
A. Barakat, P. Bianchi, W. Hachem +1
In this paper, a general stochastic optimization procedure is studied, unifying several variants of the stochastic gradient descent such as, among others, the stochastic heavy ball…
Sparse Signal Reconstruction for Nonlinear Models via Piecewise Rational Optimization
Arthur Marmin, Marc Castella, Jean-Christophe Pesquet +1
We propose a method to reconstruct sparse signals degraded by a nonlinear distortion and acquired at a limited sampling rate. Our method formulates the reconstruction problem as a…
Three Fuss-Catalan posets in interaction and their associative algebras
Camille Combe, Samuele Giraudo
We introduce -cliffs, a generalization of permutations and increasing trees depending on a range map . We define a first lattice structure on these objects and we establish g…
A character approach to directed genus distribution of graphs: the bipartite single-black-vertex case
Yichao Chen, Wenjie Fang
Given an Eulerian digraph, we consider the genus distribution of its face-oriented embeddings. We prove that such distribution is log-concave for two families of Eulerian digraphs,…
Duality of graded graphs through operads
Samuele Giraudo
Pairs of graded graphs, together with the Fomin property of graded graph duality, are rich combinatorial structures providing among other a framework for enumeration. The prototypi…
Statistics of subgroups of the modular group
Frédérique Bassino, Cyril Nicaud, Pascal Weil
We count the finitely generated subgroups of the modular group . More precisely: each such subgroup can be represented by its Stallings graph …
SPOQ -Over- Regularization for Sparse Signal Recovery applied to Mass Spectrometry
Afef Cherni, Emilie Chouzenoux, Laurent Duval +1
Underdetermined or ill-posed inverse problems require additional information for \ldd{d} sound solutions with tractable optimization algorithms. Sparsity yields consequent heuristi…
Bijective link between Chapoton's new intervals and bipartite planar maps
Wenjie Fang
In 2006, Chapoton defined a class of Tamari intervals called "new intervals" in his enumeration of Tamari intervals, and he found that these new intervals are equi-enumerated with…
Hardness of Minimum Barrier Shrinkage and Minimum Installation Path
Sergio Cabello, Éric Colin de Verdière
In the Minimum Installation Path problem, we are given a graph with edge weights and two vertices of . We want to assign a non-negative power to each ver…
Compacted binary trees admit a stretched exponential
Andrew Elvey Price, Wenjie Fang, Michael Wallner
A compacted binary tree is a directed acyclic graph encoding a binary tree in which common subtrees are factored and shared, such that they are represented only once. We show that…
Absolute root separation
Yann Bugeaud, Andrej Dujella, Wenjie Fang +2
The absolute separation of a polynomial is the minimum nonzero difference between the absolute values of its roots. In the case of polynomials with integer coefficients, it can be…
