WISER: Multimodal variational inference for full-waveform inversion without dimensionality reduction

Code to reproduce results in Ziyi Yin, Rafael Orozco, Felix J. Herrmann, "WISER: Multimodal variational inference for full-waveform inversion without dimensionality reduction", published in Geophysics.

WISER is an extension to WISE, which is also published in Geophysics.

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

wiser.jl runs the WISER algorithm in the paper to perform physics-based latent space correction.

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

The following keyword arguments can be used to reproduce the results in the WISER paper:

  • Case 1: julia wiser.jl --lr_wiser=0.004
  • Case 2: julia wiser.jl --test_snr=0.0 --amplitude=0.2 --lambda=10.0 --lr_pre=0.0004
