Abstract

fetched live from OpenAlex

The modeling of systems that exhibit near-exponential decay is most commonly done using a sum of exponentials or a stretched exponential. We note some drawbacks of these representations and present an alternative model, the stretched or compressed hyperbola, first described by E. Becquerel in the 1860s. This representation might be more helpful for interpolation, extrapolation, and classification of decays and requires only one additional parameter compared to simple exponential decay.

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.
