Abstract

fetched live from OpenAlex

The gravity method is one of the most useful mining-applicable approaches because many economic minerals are denser than their host rock. In this study, an efficient processing technique was developed and applied to invert both the synthetic gravity data generated for three thin dipping mineralized sheets of finite depth extent (with and without noises) and two dipping sheets of mineral deposits of gravity datasets from Canada and Cuba, respectively. The technique employed relies upon global particle-swarm-optimization (PSO) technique, which was used, to determine the characteristic parameters of the thin dipping sheets, including the amplitude coefficient, the depth to the upper edge, depth to the lower edge, angle of dip and the source origin (w). The processing outputs support the conclusion that, the PSO technique is fast, accurate and effective, and applicable to the noisy data. The inverted gravity data from both Canada and Cuba are mostly consistent with the available borehole control.

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.
