Abstract

fetched live from OpenAlex

A novel 1-D joint inversion algorithm for interpreting multicomponent transient electromagnetic (TEM) data was developed to invert individual data sets using independent smooth models. The model consistency is controlled by additional entries in the regularization matrix in a smooth model inversion. Compared with the traditional joint inversion approach, the new algorithm is far less likely to produce spurious model features, due to multidimensional distortions of the data. The new inversion scheme was successfully applied to field data sets recorded in Northern Israel.

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.

Full frame distilled prediction

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.
