ML-misfit: Learning a robust misfit function for full-waveform inversion using machine learning
Bingbing Sun, Tariq Alkhalifah
Most of the available advanced misfit functions for full waveform inversion (FWI) are hand-crafted, and the performance of those misfit functions is data-dependent. Thus, we propos…

A data-driven choice of misfit function for FWI using reinforcement learning
Bingbing Sun, Tariq Alkhalifah
In the workflow of Full-Waveform Inversion (FWI), we often tune the parameters of the inversion to help us avoid cycle skipping and obtain high resolution models. For example, typi…
