Abstract

fetched live from OpenAlex

Summary Seismic data reconstruction is crucial in scenarios where the original seismic data is incomplete, noisy, or corrupted. Using deep learning for the task, a model is trained to learn the characteristics of events from the existing data to predict the missing parts. Observing that a simple U-net fails to predict the poorly represented aspects of the data, we propose a new ensemble model using custom data transformation modules inside the architecture. We target weak events, conflicting dips, and high frequencies that are reported to pose challenges for a conventional deep model. Testing our method for self-supervised reconstruction of consecutive missing traces of two benchmark synthetic data and a real marine dataset shows improvements in reconstruction accuracy.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
