Abstract

fetched live from OpenAlex

In this paper, we fit the model to the actual data of cumulative cases from the 2003 SARS outbreak. The model proves a good fit for the four regions we examine, China (mainland), Canada, Hong Kong and Singapore, as evident from the high R2 values and the randomness of the residuals. In addition, we obtain second order derivatives of our curve fits to propose use of T*, the time in days taken to slow the rate of the increase in the number of cumulative SARS cases, as a measure of the effectiveness of control measures in each country. We then incorporate explanatory variables to link the model parameters to economic and demographic factors of the areas hit heavily by SARS. The work enables prediction of the future behavior of SARS or other epidemics should they ever strike again.

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.
