On the use of neural networks for full waveform inversion
Computer Methods in Applied Mechanics and Engineering, 2023 Neural networks have recently gained attention in solving inverse problems. One prominent methodology are Physics-Informed Neural Networks (PINNs) which can solve both forward and inverse problems. In the paper at hand, full waveform inversion is the considered inverse problem. The performance of PINNs is compared against classical adjoint optimization,

Transfer Learning Enhanced Full Waveform Inversion*
2023 IEEE/ASME International Conference on Advanced Intelligent Mechatronics (AIM), 2023 We propose a way to favorably employ neural networks in the field of non-destructive testing using Full Waveform Inversion (FWI). The presented methodology discretizes the unknown material distribution in the domain with a neural network within an adjoint optimization.
