Abstract

fetched live from OpenAlex

Summary 3-D MT inversion has been widely used to describe deep subsurface structures, but MT data are prone to be contaminated with noise. Although some pre-processing is done before inversion, the quality of some data can still be poor. To prevent noisy data from degrading inversion results, we may exclude noisy data in the inversion process. In this case, we need to consider the trade-off between the quality and quantity of data. We investigate the influence of the data-selection procedure on inversion results using AMT data acquired in Gyeongju, South Korea. Our inversion results show that the balance between the quality and quantity of data is important to obtain reasonable inversion results.

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.
