An Extremely Elongated Cloud over Arsia Mons Volcano on Mars: II. Mesoscale modeling
Jorge From, :, Jorge Hernández-Bernal +5
In a previous work (Hernández-Bernal et al. 2021) we performed an observational analysis of the Arsia Mons Elongated Cloud (AMEC), which stands out due to its impressive size and s…
Irreducibility of nonsmooth state-space models with an application to CMA-ES
Armand Gissler, Shan-Conrad Wolf, Anne Auger +1
We analyze a stochastic process resulting from the normalization of states in the zeroth-order optimization method CMA-ES. On a specific class of minimization problems where the ob…
Freiman's Theorem for Function Fields
Alain Couvreur, Gilles Zémor
Freiman's Theorem states that if a subset of integers has a Minkowski sum of size at most , then it must be contained in a short arithmetic progression.…
Long time behavior of a degenerate stochastic system modeling the response of a population face to environmental impacts
Pierre Collet, Claire Ecotière, Sylvie Méléard
We study the asymptotics of a two-dimensional stochastic differential system with a degenerate diffusion matrix. This system describes the dynamics of a population where individual…
Queuing dynamics of asynchronous Federated Learning
Louis Leconte, Matthieu Jonckheere, Sergey Samsonov +1
We study asynchronous federated learning mechanisms with nodes having potentially different computational speeds. In such an environment, each node is allowed to work on models wit…
Bounding the Expected Robustness of Graph Neural Networks Subject to Node Feature Attacks
Yassine Abbahaddou, Sofiane Ennadir, Johannes F. Lutzeyer +2
Graph Neural Networks (GNNs) have demonstrated state-of-the-art performance in various graph representation learning tasks. Recently, studies revealed their vulnerability to advers…
