Inexact Augmented Lagrangian Method-Based Full-waveform Inversion with Randomized Singular Value Decomposition
Jiahang Li, Hitoshi Mikada, Junichi Takekawa
Full Waveform Inversion (FWI) is a modeling algorithm used for seismic data processing and subsurface structure inversion. Theoretically, the main advantage of FWI is its ability t…
