Abstract

fetched live from OpenAlex

This paper studies some usual stochastic ordering properties of aggregate claim amounts under the Archimedean copula. Some results on the usual stochastic order of aggregate claim amounts in the independent case are shown to still hold when the random variables are dependent under the Archimedean copula. Thus, these results generalize some known results in the literature. An example is also provided to illustrate the established results.

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.
