DEVI seminar – Ludovic d’Estampes

09/03/2017 @ 11h00 – 12h00 – Big Data: from data miner to data scientist Big Data took a dominating place in the life of IT and statistician specialist. To work on these data, some very wide-spread tools are not effective any more: relational database management system (storage), SQL requests (reading/writing), R (statistical treatment). Firstly we will introduce what we hear by […]

DEVI seminar – Sébastien Gadat

23/02/2017 @ 11h00 – 12h00 – How to calculate the barycenter of a (large) graph?. This talk aims to describe an algorithm for locating the barycenter of discrete structures like weighted graphs. Such structures are commonly used for database description, or for modeling internet communication modeling, road or airline traffic, etc. The computation of this kind of structure, for a possibly […]

DEVI seminar – Sébastien Gerchinovitz

12/01/2017 @ 11h00 – 12h00 – Adversarial multi-armed bandits: an online-learning problem with robustness guarantees. In this talk we address the so-called “adversarial” multi-armed bandit problem, where no assumption is made on the sequence of payoffs received by the learner. This worst-case viewpoint provides robustness guarantees, together with online techniques for automatic parameter tuning. We will first introduce the classical bandit […]

DEVI seminar – Benoît Sainct

08/12/2016 @ 11h15 – 12h15 – Outliers detection in tax bases. Tax revenues, such as housing tax, represent a significant proportion of the resources of local and regional authorities in France. These incomes are mainly based on spontaneous statements by individuals about their own dwellings, which are regularly erroneous. To verify the veracity of these declarations is therefore a major issue. […]

DEVI seminar – Chunan Wang

24/11/2016 @ 11h15 – 12h15 – Flight Delay, Horizontal Product Differentiation and Airline Network. This paper investigates the dual roles of flight delay and horizontal product differentiation in airline network choice. A particular feature of this paper is the incorporation of all possible network structures in a three-city network, including a hub-and-spoke network (HS), point-to-point network (PP), mixed network (MX), 2-hub […]
