CONVEGNO ITALO-FRANCESE – ATELIER ITALO-FRANÇAIS

Ottimizzazione e processi dinamici in apprendimento statistico e problemi inversi
Optimisation et processus dynamiques en apprentissage et dans les problèmes inverses

8-12 settembre – septembre, 2014 | Fondazione Mediaterraneo, Sestri Levante (GE), Italia

Il convegno ha lo scopo di stimolare discussioni e possibili collaborazioni tra studiosi italiani e francesi sui seguenti temi: algoritmi per ottimizzazione convessa e le inclusioni monotone, metodi del punto fisso, teoria dei giochi, interazioni tra dinamiche discrete e continue, teoria dell'apprendimento statistico, analisi di grandi aggregazioni di dati, problemi inversi.

Le but de ce colloque est de stimuler les discussions et de favoriser la création de nouvelles collaborations entre chercheurs italiens et français sur les thèmes suivants: algorithmes pour l'optimisation convexe et les inclusions monotones, méthodes de point fixe, théorie des jeux, interactions entre dynamiques discrètes et continues, théorie de l'apprentissage statistique, traitement de masses de données, problèmes inverses.
