Abstract: In a wide range of applications, the model reduction techniques provide a well-established tool for efficient approximation of the transfer functions of large dynamical systems with multiple inputs and outputs. Rather recently the range of applications was extended to reducing the complexity of inverse problems. The optimal choice of the parameters of reduced order models (ROMs) is crucial for the efficiency of the approach. We will consider different ways to parameterize ROMs, for both forward and inverse PDE problems, and discuss optimal sampling of the parameters.
