26/11/2020 @ 10h30 – 11h30 – Airline Scheduling: learning from past errors Résumé On time performance is a key attribute to attract airline’s customers. Airlines can control on time performance by enlarging schedule times and indeed airlines have been doing so over the last decades although this implies higher costs for their operations. For instance, according to Zhang et al (2018) […]

12/11/2020 @ 10h30 – 11h30 – Graph Mining by Vertex Dismantlings Abstract When considering the topology of complex networks, an important question is how local topological constraints impact the overall topology of the network. This issue is addressed from a mathematical perspective by examining some particular families of graphs. For these graphs, the results of an exploration of the vertices in […]

08/10/2020 @ 10h30 – 11h30 – State-constrained Linear-Quadratic Optimal Control as a Kernel Regression with Hard Shape Constraints Abstract Regression problems in control or machine learning typically involve shape constraints, such as positivity or monotonicity on a prescribed compact set. Such constraints stem from qualitative priors or physical constraints, and can often be written as an infinite number of pointwise inequalities. […]
08/10/2020 @ 10h30 – 11h30 – Contrôle optimal linéaire-quadratique à contraintes d’état comme une régression par méthodes à noyaux sous contraintes de forme Résumé Les problèmes de régression en contrôle ou en apprentissage incorporent fréquemment des contraintes de forme, comme par exemple la positivité ou la monotonie de la solution sur un compact donné. Ces contraintes traduisent des a priori qualitatifs […]
