Efficient Graph Convolution for Joint Node Representation Learning and Clustering

Attributed graphs are used to model a wide variety of real-world networks. Recent graph convolutional network-based representation learning methods have set state-of-the-art results on the clustering of attributed graphs. However, these approaches…

An assessment of Multi Object Tracking on low framerate conditions

La performance des méthodes de l'état de l'art en suivi multi-objets est généralement montrée sur des vidéos à fréquence image élevée, où les objets bougent très peu d'une image à l'autre. Il y a cependant des intérêts à travailler dans le cas plus…

Human Vitamin K Epoxide Reductase as a Target of its Redox Protein

Human Vitamin K epoxide reductase (hVKORC1) is a key enzyme to reduce vitamin K. Such function requires activation of the enzyme by a redox partner delivering reducing equivalents through thioldisulphide exchange reactions. The activation process…

Receptor Tyrosine Kinase KIT: A New Look for an Old Receptor

RTK KIT regulates a variety of crucial cellular processes via its cytoplasmic (CD) domain composed of the tyrosine kinase domain crowned by highly flexible domains-juxtamembrane region, kinase insert domain and C-tail, key recruitment regions for…

The Inherent Coupling of Intrinsically Disordered Regions in the Multidomain Receptor Tyrosine Kinase KIT

RTK KIT regulates a variety of crucial cellular processes via its cytoplasmic domain (CD), which is composed of the tyrosine kinase domain, crowned by the highly flexible domains-the juxtamembrane region, kinase insertion domain, and C-tail, which…

Decision-making tools for healthcare structures in times of pandemic

The COVID-19 sanitary crisis has shed an unprecedented light on the role of modellers, mathematicians, computer scientists and data scientists in the monitoring and in the understanding of the dynamics of an epidemic. The general audience became…

Weighting Schemes for One-Shot Federated Learning

This paper focuses on one-shot aggregation of statistical estimations made across disjoint data sources for federated learning, in the context of empirical risk minimization. We exploit the role of each local sample size for this problem to develop…

Sticky nonlinear SDEs and convergence of McKean-Vlasov equations without confinement

We develop a new approach to study the long time behaviour of solutions to nonlinear stochastic differential equations in the sense of McKean, as well as propagation of chaos for the corresponding mean-field particle system approximations. Our…

Flow Redirection for Epidemic Reaction-DIffusion Control

We show we can control an epidemic reaction-diffusion on a directed, and heterogeneous, network by redirecting the flows, thanks to the optimisation of well-designed loss functions, in particular the basic reproduction number of the model. We…
