Accelerating full-waveform inversion through adaptive gradient optimization methods and dynamic simultaneous sources

Full-waveform inversion (FWI) is a procedure based on the minimization of a misfit (or cost) function applied to the difference between synthetic waveforms and real seismic traces that derives high-resolution velocity models. This is achieved through the iterative adjustment of the velocity model and/or some other physical parameters of the Earth's subsurface, which generally implies large computa...
