WISE: full-Waveform variational Inference via Subsurface Extensions

Code to reproduce results in Ziyi Yin*, Rafael Orozco*, Mathias Louboutin, Felix J. Herrmann, "WISE: full-Waveform variational Inference via Subsurface Extensions". Published in Geophysics. DOI: 10.1190/geo2023-0744.1

Software descriptions

All of the software packages used in this paper are fully open source, scalable, interoperable, and differentiable. The readers are welcome to learn about our software design principles from this open-access article.

Wave modeling

We use JUDI.jl for wave modeling and inversion, which calls the highly optimized propagators of Devito.

Conditional normalizing flows

We use InvertibleNetworks.jl to train the conditional normalizing flows (CNFs). This package implements memory-efficient invertible networks via hand-written derivatives. This ensures that these invertible networks are scalable to realistic 3D problems.

Installation

First, install Julia and Python. The scripts will contain package installation commands at the beginning so the packages used in the experiments will be automatically installed.

Scripts

gencigopenfwi.jl generates seismic data and computes common-image gathers for the CurveFault-A velocity models in the Open FWI dataset. train_openfwi.jl trains the conditional normalizing flows with pairs of velocity models and (extended) reverse-time migrations for the Open FWI dataset.

gencigcompass.jl generates seismic data and computes common-image gathers for the velocity models in the Compass dataset. train_compass.jl trains the conditional normalizing flows with pairs of velocity models and (extended) reverse-time migrations for the Compass dataset.

inference_compass.jl produces the inference results listed in the WISE paper.

The script utils.jl parses the input as keywords for each experiment.

Trained networks

4 trained conditional normalizing flows can be downloaded from dropbox, with description below

| Summary statistics \ dataset | Open FWI | Compass | |---------------------|----------|----------| | Reverse-time migration | openfwi_rtm.bson | compass_rtm.bson | | Common-image gathers | openfwi_cig.bson | compass_cig.bson |
