Researchers have developed new projection-based multifidelity linear regression methods designed for data-scarce applications with high-dimensional outputs. These techniques integrate inexpensive low-fidelity model evaluations with limited, costly high-fidelity evaluations. The methods achieve improved accuracy and higher R^2 scores compared to single-fidelity approaches, particularly in ultra low-data regimes with as few as twelve high-fidelity samples. AI
IMPACT Introduces novel statistical techniques that could improve the efficiency of training AI models when high-fidelity data is limited.
