An adaptive and efficient approach for constructing reduced‐order models (ROMs) that are robust to changes in parameters is developed. The approach is based on a greedy sampling …
Multifidelity surrogates (MFS) combine low-fidelity models with few high-fidelity samples to infer the response of the high-fidelity model for design optimization or uncertainty …
