Theme Metamodeling
Presentation
The MOCA team studies the management of numerical simulation models and their use in continuous optimization. Metamodeling encompasses here the simulation of physical systems and the two types of metamodels (models of models) :
-
Statistical metamodels (e.g., Gaussian processes) build from input-output data. The data often comes itself from the simulation of physical systems (e.g., finite elements models). We specialize in statistical metamodels built from sparse data. Such metamodels typically underly optimization algorithms.
-
Metamodels that aim at producing computer programs by describing and processing a class of models. Such metamodels may also be metacodes that algorithmically describe a set of possible program instances.
The group has contributions in domains such as continuous optimization theory and computer experiments. In addition, the group implements simulation softwares for high-performance computing, discrete events simulation software, and focuses on the numerical reproductibility of the results.
