Abstract

fetched live from OpenAlex

Traditionally, life-table variables are assigned certain values at all ages, and hence are treated as deterministic. But the survival process of the hypothetic cohort is uncertain; hence, the nature of life tables is probabilistic. This paper introduces a newly developed method to produce the probabilistic life table, in which each variable has a probability distribution rather than a sample value, at all ages except the first one. Applying the probabilistic life table to Canada, it concludesthat the recent changes in mortality are statistically significant mostly at old ages, which cannot be estimated by the traditional life table.

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.
