Hessian-based model reduction: large-scale inversion and prediction
Hessian-based model reduction was previously proposed as an approach in deriving reduced models for the solution of large-scale linear inverse problems by targeting accuracy in observation outputs. A controltheoretic view of Hessian-based model reduction that hinges on the equality between the Hessian and the transient observability gramian of the underlying linear system is presented. The mode...
متن کاملHessian-Based Model Reduction for Large-Scale Data Assimilation Problems
Assimilation of spatiallyand temporally-distributed state observations into simulations of dynamical systems stemming from discretized PDEs leads to inverse problems with high-dimensional control spaces in the form of discretized initial conditions. Solution of such inverse problems in “real-time” is often intractable. This motivates the construction of reduced-order models that can be used as ...
متن کاملHessian-based model reduction for large-scale systems with initial-condition inputs
Reduced-order models that are able to approximate output quantities of interest of high-fidelity computational models over a wide range of input parameters play an important role in making tractable large-scale optimal design, optimal control, and inverse problem applications. We consider the problem of determining a reduced model of an initial value problem that spans all important initial con...
متن کاملLarge-scale Gauss-Newton inversion of transient controlled-source electromagnetic data using the model reduction framework
The main cost of Gauss-Newton (GN) inversion of timedomain controlled-source electromagnetic (tCSEM) data is comprised of the multiple solutions of the forward problem and linear-algebraic operations using the Jacobian matrix. For large-scale 2.5D and 3D problems with multiple sources and receivers, this cost grows enormously for inversion algorithms using conventional finite-difference time-do...
متن کاملModel Reduction of Large-Scale Dynamical Systems
Simulation and control are two critical elements of Dynamic Data-Driven Application Systems (DDDAS). Simulation of dynamical systems such as weather phenomena, when augmented with real-time data, can yield precise forecasts. In other applications such as structural control, the presence of real-time data relating to system state can enable robust active control. In each case, there is an ever i...
