Seismic Waveform Inversion Capability on Resource-Constrained Edge Devices [PDF]
Journal of Imaging, 2022 Seismic full wave inversion (FWI) is a widely used non-linear seismic imaging method used to reconstruct subsurface velocity images, however it is time consuming, has high computational cost and depend heavily on human interaction.

Seismic Waveform Inversion by Stochastic Optimization [PDF]
International Journal of Geophysics, 2011 We explore the use of stochastic optimization methods for seismic waveform inversion. The basic principle of such methods is to randomly draw a batch of realizations of a given misfit function and goes back to the 1950s.

Data-Driven Seismic Waveform Inversion: A Study on the Robustness and Generalization [PDF]
IEEE Transactions on Geoscience and Remote Sensing, 2020 Acoustic- and elastic-waveform inversion is an important and widely used method to reconstruct subsurface velocity image. Waveform inversion is a typical non-linear and ill-posed inverse problem. Existing physics-driven computational methods for solving waveform inversion suffer from the cycle skipping and local minima issues, and not to mention ...

Rapid Seismic Waveform Modeling and Inversion With Neural Operators
IEEE Transactions on Geoscience and Remote Sensing, 2023 Seismic waveform modeling is a powerful tool for determining earth structure models and unraveling earthquake rupture processes, but it is usually computationally expensive. We introduce a scheme to vastly accelerate these calculations with a recently developed machine learning paradigm called the neural operator.
