21/07/2021 – 23/07/2021 @ Toute la journée – As for GSI’13/GSI’15/GSI’17/GSI’19, the objective of this 5th SEE GSI’21 conference, hosted in Sorbonne University, is to bring together pure/applied mathematicians and engineers, with common interest for Geometric tools and their applications for Information analysis and Learning. It emphasizes an active participation of young researchers to discuss emerging areas of collaborative research on “Geometric Science […]
24/06/2021 @ 10h00 – 11h00 – How Humans Judge Machines Abstract: How would you feel about losing your job to a machine? How about a tsunami alert system that fails? Would you react differently to acts of discrimination performed by a machine or a human? How about public surveillance? How Humans Judge Machines compares people’s reactions to actions performed by humans […]
10/06/2021 @ 15h00 – 16h00 – Network visualization and academic storytelling Abstract: Network science is a rapidly growing multidisciplinary area that allows us to understand the dynamics of interconnected systems: social, digital, physical, biological, economic, political, and others. This talk will cover ideas related to communicating network research, visualizing network data, and presenting relational information to academic audiences. The discussion will […]
27/05/2021 @ 10h30 – 11h30 – Analyse et visualisation de données sportives : de la vidéo à l’amélioration de la performance Abstract: Le sport a récemment été révolutionné par l’utilisation de données, pour l’analyse de trajectoires de joueurs et de stratégies de jeu. Je présenterai mes travaux récents avec les fédérations sportives olympiques de natation et de tennis de table, qui […]
08/04/2021 @ 10h30 – 11h30 – Optimal (weak) transport and barycenters Abstract: We introduce the weak barycenter of a family of probability distributions, based on the recently developed notion of optimal weak transport of measures. We provide a theoretical analysis of the weak barycenter and its relationship to the classic Wasserstein barycenter, and discuss its meaning in the light of convex […]
25/03/2021 @ 10h30 – 11h30 – The impact of LCCs’ growth on the air networks of European NCs Abstract: We study how European network carriers’ (NCs’) air networks evolved in response to competitive inroads by low-cost carriers (LCCs) over the last two decades. As LCCs added routes and increased their market shares, NCs reacted by reconfiguring their networks. Specifically, we find […]
11/03/2021 @ 10h30 – 11h30 – How to Regulate Modern Aiports? Abstract: In addition to the provision of aeronautical services, modern airports are also in charge of providing commercial services to passengers as well as investing in their infrastructure. We investigate the optimal regulation of airports and its implementation. Optimal prices for aeronautical services and commercial services follow a Ramsey-Boiteux pricing […]
11/02/2021 @ 10h30 – 11h30 – Agglomeration, Transport and Productivity: Evidence from Toulouse Metropolitan Area Abstract: Economic activity tends to be highly concentrated. These agglomeration or concentration forces are driven by spatial externalities on productivity, and are named agglomeration externalities. Transport improvements – by reducing the interaction cost between economic agents placed in different locations – can extend the geographic scope […]
28/01/2021 @ 10h30 – 11h30 – The Impact of Covid19 on Airline Operations: A Comparative European and North American Analysis The presentation will be given in English. http://meet.jit.si/SeminaireDEVI
10/12/2020 @ 10h30 – 11h30 – A coupling of the spectral measures at a vertex Abstract I will introduce a particular coupling of the spectral measures at the vertices of a graph, whose moments count the rooted closed paths in the graph. The resulting joint spectral measure verifies numerous interesting properties that allow to recover minors of analytical functions of the […]
