Abstract

Model order reduction for parameterized systems has gained a lot of attention in the last two decades. In this talk we will focus on projection based model order reduction and their efficient application to solve large scale PDE constrained optimization problems. We will discuss learning strategies, such as adaptive enrichment as well as a combination of reduced order models with machine learning approaches in the context of time dependent problems. Concepts of rigorous certification and convergence will be presented, as well as numerical experiments that demonstrate the efficiency of the proposed approaches.
