- Folders are necessary library for running simulations.
- use xxx_mfGent_vyy.m to generate multi fidleity data.
- In the saved .mat data, Ytr is a cell with F fidelity. Each cell is a tensor with N samples; each samples is a d1xd2 matrix.(or a vector).
Ytr{1} and Ytr{2} maybe have different dimensionality for each fidelity. Thus, we have the interpolation version, Ytr_interp, where the dimensionality is aligned for each fidelity.
- Yte is the testing data.
- if Ytr2 presents, it means a different type of output.
