DEVI Seminar- Agnès Lagnoux (IMT Toulouse)

24/10/2019 @ 10h30 – 11h30 – On the Estimation of Covariance Parameters of Gaussian Processes Summary: Because of their simplicity and flexibility, which make it possible to encapsulate a large class of models, Gaussian processes have become very popular in recent years, and are widely used in spatial statistics to interpolate observations and propose meta-models (for example, in kriging). Gaussian processes […]

DEVI Seminar – Tat-Dat Tô

12/09/2019 @ 10h30 – 11h30 – A deep learning approach for the shortest path search problem and some perspective applications. We propose a deep learning approach for shortest path search problem in which the shortest length can be learned via a deep Neuron Network. We also propose an algorithm which permit to run the A-star algorithm in real time for the […]

DEVI Seminar – Michel Boyom (university of Montpellier II)

27/06/2019 @ 10h30 – 11h30 – Structure of complex systems Complex systems are most often considered from the viewpoint of measurable spaces. Nevertheless, this approach can give rise to invariants from different mathematical structures: topological or differential. The purpose of this talk is to present some perspectives on the structuring of data: At the conceptual level. Equipping a *complex system* with […]

DEVI Seminar – Jean-Pierre Florens (TSE)

13/06/2019 @ 10h30 – 11h30 – Convolution on networks This work analyses the estimation of a linear model Y=Z*b + U where Y,U, Z and b are functions defined on a network and where the convolution operator * is defined through a Fourier transform defined on the network. Networks may be usual networks, homogenous spaces or more generally spaces provided with […]

DEVI Seminar – Xavier Fageda (University of Barcelona)

16/05/2019 @ 15h00 – 16h00 – GLOBALIZATION, LONG-HAUL FLIGHTS AND INTER-CITY CONNECTIONS We estimate a model that identifies the impact of long-haul non-stop flights on traffic flows in inter-city markets, using data that account for the true origin and destination of passengers. In particular, we analyze whether long-haul non-stop flights may have a positive and significant effect on traffic flows in […]

Worshop Agency Research Team (ART) : “Aviation Economics and Business Models”

16/04/2019 – 17/04/2019 @ Toute la journée – The workshop focusses on the business models of various aviation stakeholders and how they are likely to evolve in the future, e.g. as a function of new traffic participants as well as the impact of regulation and incentives schemes, including environmental regulation. The workshop is open to additional topics and presentations. Agenda

DEVI Seminar – Volodymir Bilotkach (Newcastle University)

07/03/2019 @ 10h30 – 11h30 – Causes and Effects of Air Traffic Delays: Evidence from Aggregated Data This study uses aggregated data on concentration, delays, and airfares from the US airports to shed light on two issues. First, we examine the concentration-delays relationship to contribute to the airport- congestion self-internalization debate. Our study is the first investigation of this issue that […]

Séminaire DEVI – Nicole Adler

31/01/2019 @ 10h30 – 11h30 – Introducing Competition in European Air Traffic Control Provision using Game Theoretic Principles The overall goal of the research is to investigate how to introduce competitive incentives in the air traffic management sector so as to best contribute to the European high-level policy objectives for aviation. We develop a two-stage, network congestion game in which multiple […]

DEVI Seminar – Eric SanJuan

24/01/2019 @ 10h30 – 11h30 – Contextualisation basée sur le Wikipedia Les assistants personnels automatiques pour grand public utilisent massivement le WikiPedia pour générer les réponses à des questions factuelles générales ou comme source de contextualization. Le WikiPedia constitue aussi l’une des principales sources d’élaboration des graphes de connaissances utilisés par les moteurs de recherche. Il s’agit d’une ressource encyclopédique communautaire […]
