.. _meta_modeling: Meta modeling ============= The current section is dedicated to the building of an analytical approximation of the response of a given model. Such an approximation is commonly referred to as a response surface in the literature. This methodology is relevant if each model evaluation is time consuming. Indeed, once a response surface has been built up, the various propagation steps may be applied at a negligible cost. A special focus will be given to polynomial response surfaces. .. toctree:: :maxdepth: 1 taylor_expansion polynomial_least_squares polynomial_sparse_least_squares kriging Functional chaos ---------------- .. toctree:: :maxdepth: 1 orthogonal_polynomials chaos_basis enumeration_strategy functional_chaos cross_validation
