Abstract

We present Inversionson, a Python package that fully automates modern full-waveform inversions (FWI).
It supports traditional FWI, which uses the same set of events and a single simulation mesh in each iteration, as well as more advanced workflows that exploit the use of dynamic mini-batches and wavefield-adapted meshes.
These recently introduced advancements can be time-consuming and challenging to implement but offer major benefits, such as much lower computing cost in favourable cases and the ability to use much larger datasets, while having a built-in optimal experimental design.
Inversionson, in essence, acts as a control center...  more
