2011-12 UQ Program: Methodology Opening Workshop and Tutorials

The Opening Workshop for the Methodology theme of the SAMSI program on Uncertainty Quantification was held on Wednesday-Saturday, September 7-10, 2011, at the Radisson RTP in Research Triangle Park, NC. The location is in close proximity to SAMSI.

From mid-day Wednesday to Saturday evening, invited speakers gave presentations. For each of the five themes described below, one presentation was introductory. There was a poster session and reception on Wednesday, September 7. Additional activities were organized later during the weekend.

The workshop focused on the following five complementary themes

(1) Foundations, theory and methods that are related to uncertainty quantification, including for example; treatment of model error, inference with multi-models, treatment of multiscale models, numerical error estimation, reduced order modeling, and theoretical foundations of various UQ problems.

(2) Representation and propagation of uncertainty, including for example; efficient representations of uncertainty, integration of different representations of uncertainty and error, propagation of uncertainty through complex physical models, exploiting mathematical structure of models for propagation, and identification of sensitivity of models.

(3) Data assimilation, including for example; incorporating information from disparate and sparse data sets, filtering and forecasting, response surface techniques, sampling based approaches, derivative/variational-based approaches.

(4) Inverse problem and calibration, including for example; treating sparse and noisy data, use of reduced order models, regularization and optimization, integration of parameter and prediction uncertainty, use of derivative information from physics-based models.

(5) Rare events, including for example; use of reduced order models, use of computational and physics models to detect rare events, investigation of relevant statistical methodologies, optimization techniques.
