Fourier-DeepONet for full waveform inversion (FWI)

The data and code for the paper M. Zhu, S. Feng, Y. Lin, & L. Lu. Fourier-DeepONet: Fourier-enhanced deep operator networks for full waveform inversion with improved accuracy, generalizability, and robustness. Computer Methods in Applied Mechanics and Engineering, 416, 116300, 2023.

Datasets

Run data_gen_f.py, data_gen_loc.py, and data_gen_loc_f.py to generate seismic data of FWI-F, FWI-L, and FWI-FL, respectively.

Code

In train.py and test.py, change the arguements 'dataset' and 'task' in main function as needed.

Run train.py for training, and then run test.py for testing.
