Accelerating wave simulations with neural dispersion correctors
Felipe Rincón, Andreas Fichtner, Mattia Aleardi +2
We present a Fourier neural operator network, designed to correct dispersion errors in numerical wave simulations. The neural dispersion corrector enables the replacement of a comp…

Annealed Stein Variational Gradient Descent for Improved Uncertainty Estimation in Full-Waveform Inversion
Miguel Corrales, Sean Berti, Bertrand Denel +3
In recent years, Full-Waveform Inversion (FWI) has been extensively used to derive high-resolution subsurface velocity models from seismic data. However, due to the nonlinearity an…
