Expert Knowledge and Multivariate Emulation

Summary: [This abstract is based on the authors' abstract.] Features occurring in models of complex systems such as the thermosphere-ionosphere electrodynamics general circulation model of the upper atmosphere are a challenge to standard emulation approaches. It is demonstrated how the outer product emulator can be used for efficient calculation, especially for predictive diagnostics for model choice and validation. The emulator is used to verify the underlying computer code and to quantify the qualitative physical understanding.
