Active emulation of computer codes with Gaussian processes – Application to remote sensing
作者:
Highlights:
• Introduction of methodology for active multi-output Gaussian process emulators.
• Gaussian processes allow the construction of accurate, compact and interpretable emulators.
• Adaptive sequential construction of both the emulator and look-up-table.
• New acquisition function combines function geometry and predictive uncertainty.
• Application to complex codes used on remote sensing leads to considerable computational savings.
