The application of an optimal transport to a preconditioned data matching function for robust waveform inversion
B Sun, T Alkhalifah - Geophysics, 2019 - library.seg.org
Full-waveform inversion (FWI) promises a high-resolution model of the earth. It is, however,
a highly nonlinear inverse problem; thus, we iteratively update the subsurface model by …

Robust full-waveform inversion with radon-domain matching filter
B Sun, T Alkhalifah - Geophysics, 2019 - library.seg.org
Cycle skipping is a severe issue in full-waveform inversion. One option to overcome it is to
extend the search space to allow for data comparisons beyond the “point-to-point” …

We have developed a method to obtain a misfit function for robust waveform inversion. In
this method, called adaptive traveltime inversion (ATI), a matching filter that matches …

Joint minimization of the mean and information entropy of the matching filter distribution for a robust misfit function in full-waveform inversion
B Sun, TA Alkhalifah - IEEE Transactions on Geoscience and …, 2020 - ieeexplore.ieee.org
A full-waveform inversion (FWI) is a highly nonlinear inversion methodology. FWI tends to
converge to a local minimum rather than a global one. We refer to this phenomenon as …
