Abstract

fetched live from OpenAlex

Abstract Utility is a quantitative expression of strength of preference. The more something is preferred, the greater is its utility. Formal utility theory for decision making under uncertainty was defined by von Neumann & Morgenstern. Utilities in their theory are measured using the standard gamble. Alternatively, time trade‐off and visual analog scales are used to measure preferences, and these also are sometimes called utilities. Utilities are an integrative measure of health‐related quality of life. Utilities, representing quality of life can be combined with quantity of life to form quality‐adjusted life years. These, in turn, are used in cost–utility analyses. For most clinical studies, the simplest and the preferred way to measure utilities is to use one of the multiattribute health status classification systems that include a utility scoring formula; for example, EuroQol EQ‐5D, Health Utilities Index, or Quality of Well‐Being Scale.

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.
