23/03/2021 – 14h00-15h00 – Online Control and Feedback stabilization for entropy solutions to conservation laws Vincent Perrollaz (IDS, Université de Tours) Abstract. Hyperbolic conservation laws are partial differential equations that are used to model many kind of physical phenomena: gas dynamics, traffic flow, electromagnetism, shallow water theory, combustion theory… However even the simplest equation of […]
The twenty-sixth UQSay seminar on UQ, DACE and related topics, organized by L2S, MSSMAT, LMT and EDF R&D, will take place online on Thursday afternoon, March 18, 2021. 2–3 PM — Amaya Nogales Gómez (I3S, Sophia Antipolis) — [slides] Incremental space-filling design based on coverings and spacings: improving upon low discrepancy sequences The paper addresses […]
Speaker — Ouafae Karmouda (SIGMA team at CRIStAL laboratory, Lille, France) Abstract — Supervised learning is a major task to classify datasets. In our context, we are interested into classification from high-order tensors datasets. The “curse of dimensionality” states that the complexities in terms of storage and computation grow exponentially with the order. As a […]
09/03/2021 – 14h00-15h00 – Online On the utilization of Macroscopic Information for String Stability of a Vehicular Platoon Alessio Iovine (L2S, CentraleSupèlec) Abstract. Interconnected autonomous vehicles have the capability toreduce stop-and-go waves propagation and traffic oscillations via the concept of String Stability. To improve the platoon stability, several cases of information sharing are usually considered […]
Speaker — Claire Boyer (Sorbonne Université) Abstract — This work investigates the problem of signal recovery from undersampled noisy sub-Gaussian measurements under the assumption of a synthesis-based sparsity model. Solving the l1-synthesis basis pursuit allows to simultaneously estimate a coefficient representation as well as the sought-for signal. However, due to linear dependencies within redundant dictionary […]
