Abstract -- MS 1307 -- Non-intrusive surrogate models for uncertainty quantification in high dimensions
Uncertainty quantification has become a key challenge in modern engineering, whether it is used for assessing the safety of systems (structural reliability methods), for finding the distributions and moments of quantities of interest, for determining the key parameters of the problem (sensitivity analysis), or for optimizing under safety constraints (reliability-based design optimization - RBDO). Various techniques for solving these problems have received much attention in the mechanical, civil, and aerospace engineering communities over the past two decades.
However, accurate computational models (e.g., finite element analysis) of complex structures or systems are often costly. A single run of the model may last minutes to hours, even on powerful computers. In order to use these models in analyses that require repeated calls to the computer code, it is necessary to develop a substitute that may be evaluated thousands to millions of times at low cost: these substitutes are referred to as meta-models or surrogate models.
The “curse of dimensionality”, i.e. the exploding complexity observed when the number of input variables increases, is a recurrent problem in surrogate modeling. The aim of this mini-symposium is to confront various kinds of meta-modeling techniques in the context of uncertainty propagation, including polynomial chaos expansions, Kriging, support vector regression, etc. and to discuss the recent advances towards solving high dimensional problems.
