Twist Flow for Inverse Problems

Shiqin Zeng, Zijun Deng, Felix J. Herrmann · 2026

In Bayesian inverse problems, posterior sampling requires generating samples that are consistent with given observations while capturing the range of plausible solutions. Direct conditional generative models introduce latent noise to model this ambiguity, but paired inverse-problem training can still encourage an almos …

Self-attention summary networks for subsurface velocity-model building from common-image gathers

Shiqin Zeng, Yunlin Zeng, Abhinav Prakash Gahlot وآخرون · 2026

Common-image gathers (CIGs) contain physically meaningful information about velocity-model errors through reflector focusing and residual moveout, but in conventional imaging workflows they are typically used only as diagnostic tools. In this work, we propose a multiscale self-attention summary network that maps high-d …
