MFNN test dataset

[AmosJoseph]

Hi, I build MFNN based on low-fidelity FEM data (many) and high-fidelity experimental data (only a few).

Is it ok to use also high-fidelity experimental data as test dataset?

If not, then high-fidelity experimental data is not enough, how to validate predictive accuracy of MFNN?

Check cross validation.
