Multi-Fidelity

Deep Residual Coregionalization (DRC)

To run the code:

cd Multi-Fidelity/Deep-Residual-Coregionalization
python run-baselines.py -domain=Heat -method=dc -rank=5 -fold=1

If you need more data(e.g. different domain(Burgers, Poisson, NS), different method, different fold), you can get from IFC(Infinite-Fidelity-Coregionalization) project by running

cd Infinite-or-Continuous-Fidelity/Infinite-Fidelity-Coregionalization
python process-data-drc.py

Therefore, you can copy the data from DRC-pde-data folder to exp_data_dc in Deep-Coregionalization.

Please cite the paper if you find this code useful.
