SIAM Southeastern Atlantic Section Conference

September 18-19, 2021

Mini-symposium (MS)

MS1:  Reduced Order Modeling in the Age of Data

Organizers: Traian Iliescu, Virginia Tech

                    Alessandro Veneziani, Emory University

                    Omer San, Oklahoma State University

Abstract: This mini-symposium aims at giving a survey of recent developments in reduced order modeling, with a special emphasis on data-driven modeling and machine learning.  Computational modeling, numerical analysis, and applications to realistic engineering, geophysical, and biomedical problems will be covered in this mini-symposium. Both achievements and open problems in reduced order modeling will be discussed.
