Chapter
Engineering Applications
Multi-fidelity (MF) surrogates can balance the prediction accuracy and computational cost by augmenting a few expensive high-fidelity (HF) samples with many inexpensive low-fidelity (LF) data. Consequently, MF...

Chapter
Hierarchical Multi-fidelity Surrogate Modeling
Most of the existing multi-fidelity (MF) surrogates assume that high-fidelity (HF) models are generally more accurate than low-fidelity (LF) models but LF models are less expensive than HF models. In other wor...
