Building kriging models using hierarchical codes with different levels of accuracy.

Abstract : This paper deals with the Gaussian process based approximation of a code which can be run at different levels of accuracy using co-kriging. This method allows us to improve a surrogate model of a complex computer code using fast approximations of it. In particular, we focus on the case of large number of code levels. A thermodynamic example is used to illustrate a 3-level co-kriging.
