Arguments graphiques simples pour comprendre la spécification du modèle d’espérance non additive d’utilité et l’intégrale de Choquet
Bibliographic record
Abstract
Le modèle d’espérance non additive d’utilité ou Choquet Expected Utility (Schmeidler, 1989) est une généralisation du modèle d’espérance d’utilité mettant en oeuvre une mesure de vraisemblance non nécessairement additive et faisant appel au concept d’intégrale de Choquet. L’objectif de cet article est de présenter ce type d’intégrales à l’aide d’arguments graphiques simples et de clarifier l’articulation existant entre les spécifications rencontrées dans l’incertain probabilisé et celles rencontrées dans l’incertain non nécessairement probabilisé.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
