A practical implementation of data-space Hessian in the time-domain extended-source full-waveform inversion
Gaoshan Guo, Stephane Operto, Ali Gholami +1
Full-waveform inversion (FWI) with extended sources first computes wavefields with data-driven source extensions, such that the simulated data in inaccurate velocity models match t…
Full waveform inversion beyond the Born approximation: A tutorial review
Stephane Operto, Ali Gholami, Hossein S. Aghamiry +3
Full Waveform Inversion can be made immune to cycle skipping by matching the recorded data arbitrarily well from inaccurate subsurface models. To achieve this goal, the simulated w…
Wave simulation in non-smooth media by PINN with quadratic neural network and PML condition
Yanqi Wu, Hossein S. Aghamiry, Stephane Operto +1
Frequency-domain simulation of seismic waves plays an important role in seismic inversion, but it remains challenging in large models. The recently proposed physics-informed neural…
Randomized source sketching for full waveform inversion
Kamal Aghazade, Hossein S. Aghamiry, Ali Gholami +1
Partial differential equation (PDE) constrained optimization problems such as seismic full waveform inversion (FWI) frequently arise in the geoscience and related fields. For such…
Anderson accelerated augmented Lagrangian for extended waveform inversion
Kamal Aghazade, Ali Gholami, Hossein S Aghamiry +1
The augmented Lagrangian (AL) method provides a flexible and efficient framework for solving extended-space full-waveform inversion (FWI), a constrained nonlinear optimization prob…
