Data-Driven Model Reduction
Organizers: Athanasios Antoulas (Rice University).

Model reduction is commonly used in the simulation and control of complex physical processes. The systems that inevitably arise in such cases are often too complex to meet the expediency requirements of interactive design, optimization, or real time control. Model reduction has been devised as a means to reduce the dimensionality of these complex systems to a level that is amenable to such requirements. The ensuing methods have been an indispensable tool for speeding up the simulations arising in various engineering applications involving large-scale dynamical systems.

Generally, large systems arise due to accuracy requirements on the spatial discretization of partial differential equations for fluids, structures, etc.

This mini-symposium will present a variety of recent results in model reduction with particular emphasis on approaches which are based on input-output data, as opposed to an explicit description of the underlying system in terms of equations.
