Abstract

fetched live from OpenAlex

With the latest advances in airborne geophysical data acquisition, the search for fast and semi-automatic data interpretation tools has become critical. Euler deconvolution is a rapid and reliable method for gravity and magnetic source mapping. However, the large number of solutions that it usually generates makes it impractical. The current work details the application of clustering and kernel density distribution techniques to a standard Euler generated dataset. This approach allows the discrimination of statistically valid solutions and the extraction geologically relevant structural (strike and dip) information from the solution database. The output of this algorithm can be used as an input to any 3D geological modeling package.

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.
