Abstract

fetched live from OpenAlex

Marine mammals are a K-selected relict megafauna that escaped the mass extinctions that affected their terrestrial counterparts at the end of the Pleistocene. Over the last 500 years they have been severely impacted as humans have mastered the marine environment. Some stocks and species went to extinction, and extinction of others was narrowly averted through international efforts regulating commercial exploitation. In the late 20th century new threats arose through contamination of the marine environment and these will be exacerbated and added to as human numbers double and economies grow over the next century.

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.
