4. Rationale:

Significant research has been expanded over the past several decades to develop model-based predictions into sharp estimators of the actual behavior of natural and physical phenomena. The vision of computational experiments paralleling and predicting the outcomes of physical tests is already a driving force and an accepted model for the future of scientific computing. A key component in realizing this vision is the accurate and meaningful quantification of errors in model-based predictions.

The estimation of errors associated with the discretization of the partial differential equations governing a particular problem is a very active research field. The interpretation let alone estimation of errors associated with natural variability and limited data is, on the other hand, an emerging field. This Uncertainty Quantification field addresses issues that are paramount to the validation of model-based predictions and their use as substitutes or supplements to physical tests.

6. Description:

This short course will present an overview of the basic issues addressed by Uncertainty Quantification. A mathematical formulation of these issues
will be presented that is consistent with approximation theory as used and implemented in scientific computing. Outstanding theoretical and computational
issues will be delineated and a spectrum of approaches for addressing them will be reviewed.

7. Course Objectives:

Attendees will be presented with an overview of analytical and computational methods in the area of Uncertainty Quantification. A panoramic view of the
field will be presented with appropriate connections to computational sciences. An assessment will be provided of both the current-state-of the art and of
research needs.
