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…

A discrete adjoint method for deterministic and probabilistic eikonal-equation-based inversion of traveltime for velocity and source location
Andrea Zunino, Scott Keating, Andreas Fichtner
Seismic traveltime tomography represents a popular and useful tool for unravelling the structure of the subsurface across the scales. In this work we address the case where the for…
