Parameter estimation is widely applied in the context of model calibration using parameter fitting and estimation of the model confidence. The minisymposium focuses on parameter estimation of PDE based models. In particular, the following main aspects are considered:
1) Model reduction
2) Uncertainty quantification
All methods for model reduction (order reduction, adaptivity etc.) that allow for a reduction of storage and/or computational time maintaining the same response characteristics of the original system are of interest for the minisymposium. One important aspect is the evaluation of the accuracy of the reduced model. An additional essential aspect for parameter estimation problems is the prediction of the confidence of the fitted parameters and/or of a quantity of interest (QI), which depends on the fitted values. In the minisymposium techniques to estimate the variance (and covariance) of the parameters and/or QI using a sensitivity approach are considered. Approaches as stochastic nite elements are within the scope of the minisymposium. Furthermore, methods for optimal experimental design based on deterministic approaches are considered important in this context.
