Abstract

fetched live from OpenAlex

We conducted a Logistic regression analysis to study the effectiveness of a system of stroke care delivery promoted in Ontario,Canada. Compared with piecewise regression model used in KAPRAL etc,Logistic regression model considers that decreased rate of death may vary with time and assumes that death rate will eventually remain stable at the range of a certain value after promoting Ontario Stroke System. It leads to some new understanding of the effectiveness of Ontario Stroke System. In our empirical study Logistic regression obtains a better fitting cure which is significant for the statistical test. In addition,we find alternative inflection point compared with KAPRAL etc,which may have interesting interpretation.

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.
