Abstract

fetched live from OpenAlex

ABSTRACT Inversion of magnetic data into 3D models is becoming commonplace. The theoretical basis of the method is well established and has been extended to include constraints based on physical properties and geologic information. Nevertheless, only limited attention is paid to assessing the reliability of computed models, which usually involves deriving some measure of how well features within the models can be resolved. Resolution lengths determined from resolution matrices can be unrealistically small, suggesting that the recovered models are more reliable than they really are. One cause of this effect is the calculated model itself, which directly influences the character of the resolving functions. We have developed an approximate resolution measure not affected by the calculated model, and we found it to give more realistic resolving lengths. This approximation is computationally less demanding and can be calculated prior to inversion. It suggests that the resolution length is equal to the depth of the parameter or model feature of interest.

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.

Teacher imitation

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.
