Diffusion-guided optimization for full waveform inversion
Yiran Shen, Yangkang Chen, Björn Engquist
We present a diffusion-guided full waveform inversion (FWI) study in which pretrained diffusion generative models are used as learned regularizers inside a PDE-constrained seismic…
Application of Optimal Transport and the Quadratic Wasserstein Metric to Full-Waveform Inversion
Yunan Yang, Björn Engquist, Junzhe Sun +1
Conventional full-waveform inversion (FWI) using the least-squares norm () as a misfit function is known to suffer from cycle skipping. This increases the risk of computing a…
Optimal Transport for Seismic Full Waveform Inversion
Bjorn Engquist, Brittany D. Froese, Yunan Yang
Full waveform inversion is a successful procedure for determining properties of the earth from surface measurements in seismology. This inverse problem is solved by a PDE constrain…
