Instead of seeking only a single velocity model, our method aims to draw samples from the posterior distribution of migration-velocity models conditioned on the observed shot data. In this context, we train conditional normalizing flows (CNFs) to approximate this posterior distribution. To simply the mapping between seismic image and shot data, we use common-image gathers (CIGs) as an information-preserving physics-informed summary statistics to embed the shot data, and then train the CNFs on pairs of velocity models and CIGs [@yin2023wise]. After training, the inverse of CNF turns random realizations of the standard Gaussian distribution into posterior samples (velocity models) conditioned on any seismic observation that is in the same statistical distribution as the training data, shown in the upper part of the flowchart. ## Physics-based refinement @@ -22,4 +24,9 @@ While the trained amortized CNF can generate posterior velocity samples instanta To understand how the uncertainty in the migration-velocity models propagates to imaged reflectors, forward uncertainty is assessed by carrying out high-frequency imaging for different posterior velocity samples, shown on the right-hand side of the flowchart. The uncertainty in the imaged reflectors is revealed in variance in both the amplitude and the positioning of the reflectors. -![](./figs/workflow.png){width=99%} \ No newline at end of file +![](./figs/WISER-workflow.pdf){width=99%} + +## References + +::: {#refs} +::: \ No newline at end of file diff --git a/_quarto.yml b/_quarto.yml index 0e675eb..73864c1 100644 --- a/_quarto.yml +++ b/_quarto.yml @@ -18,7 +18,7 @@ website: contents: - file: DigitalTwin/abstract.qmd text: "Digital twin with control" - - file: WISER/abstract.qmd + - file: WISER/paper.qmd text: "Full-waveform variational inference" page-footer: center: @@ -31,6 +31,7 @@ format: light: flatly dark: darkly css: styles.css + lightbox: True toc: true link-external-newwindow: True diff --git a/index.qmd b/index.qmd index 61da4bd..e31ecd0 100644 --- a/index.qmd +++ b/index.qmd @@ -4,10 +4,10 @@ title: "Image2024" This is a Quarto website. -All submissions to the Image23 conference with additional figures, references, ... +All submissions to the Image24 conference with additional figures, references, ...
