Journée-séminaire de combinatoire

(équipe CALIN du LIPN, université Paris-Nord, Villetaneuse)

Le 26 février 2019 à 14h00 en B107, Noriyoshi Sukegawa nous parlera de : On distance computation of marked point process: Mathematical optimization in nonlinear dynamics

Résumé : A marked point process is a series of events generated along the time which is accompanied with some additional information. Examples of the marked point processes include trades in foreign exchange markets, earthquake activities, and times at which a neuron fires an action potential. Calculating a distance between two time windows of a given marked point process is the first step to analyze it from the viewpoint of nonlinear dynamics.
In this talk, I would like to introduce a new faster algorithm for the distance computation, and show its validity through preliminary numerical experiments. I also discuss the median computation problem. This talk is based on my recent joint work with Prof. Yoshito Hirata (Univ. of Tokyo, Japan).
