Abstract

fetched live from OpenAlex

Abstract During the progress of the COVID-19, many countries have observed that their active cases tend to rise again after falling for some time. This may cause some mathematical models like the one discussed in [2] tend to make errors in the future prediction. We discuss a simple method to better the future prediction in such cases. This method is applied on the active and total cases data for the countries USA and Canada. In the case of Canada, the method succeeded in predicting the date when the active cases began to decrease. In the case of USA, a major improvement in prediction was observed when the method was applied: the predicted active and total cases are 1465602 and 2729015 for June 30; whereas the actual values are 1455400 and 2728856. We also give the active and total cases prediction for Canada and the USA for the first week of July 2020.

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.
