DeepStratNet: A Context-Aware Coordinate Regression Framework for Seismic Horizon Tracking under Sparse Labels

DeepStratNet introduces a context‑aware coordinate regression framework for seismic horizon tracking that directly predicts time/depth coordinates at each lateral position, avoiding the need for dense segmentation masks. The lightweight regression head, combined with an LSTM for inter‑slice context and geology‑informed regularization, outperforms traditional segmentation models on a New Zealand seismic volume, especially under sparse labeling. The method also provides a built‑in quality control by capturing local geological variations through prediction variability across traces.

Generative wave propagator

arXiv:2607. 04440v1 Announce Type: cross Abstract: Seismic wavefield simulation is fundamental to seismology, but conventional finite-difference (FD) methods remain limited by numerical dispersion and stability constraints, which often require dense spatial grids and small time steps and thereby severely limit the effectiveness of iterative inversion workflows.
