Abstract

fetched live from OpenAlex

We've all heard about cases in which a patient presumed to have died from acute myocardial infarction was discovered at autopsy to have had an aortic dissection, or a patient who presented with decompensated liver failure from presumed alcoholic cirrhosis but proved at autopsy to have widely metastatic hepatocellular carcinoma. Indeed, an extensive literature documents the frequency with which autopsy reveals clinically significant diagnoses that were missed before death.1 Autopsies also generate more accurate vital statistics, provide pathological descriptions of new diseases, and offer powerful tools for education and quality assurance (see Benefits of Nonforensic Autopsies). Yet despite these benefits, . . .

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.
