Abstract

fetched live from OpenAlex

GPR is a powerful tool for geophysical near‐surface investigations. It is capable of delivering a high‐resolution image of the subsurface structure. However, if the underground consists of many reflecting events, the analysis and interpretation of the data can be very complicated. In this paper, we report on a new image decomposition technique that is based on Local Radon transforms. This technique is a parametric local dip‐decomposition method that allows us to extract features or reconstruct GPR data. After reconstructing the data with only a subset of dips, the interpretation of the data improves substantially. We demonstrate the capabilities of this technique at GPR data acquired at the highly fractured summit of Turtle Mountain (Alberta/Canada).

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. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
