%description
Multi-Fidelity emulator for data from computer simulations of the same
underlying system but at different input locations and fidelity level,
where both the input locations and fidelity level can be continuous.
Active Learning can be performed with an implementation of the Integrated
Mean Square Prediction Error (IMSPE) criterion developed by Boutelet and
Sung (2025, <doi:10.48550/arXiv.2503.23158>).
