Abstract

fetched live from OpenAlex

Ce mémoire traite deux problèmes : en premier lieu, l'estimation paramétrique par intervalle dans un contexte où il y a des contraintes sur le paramètre et, en deuxième lieu la probabilité de fausses découvertes lorsqu'on réalise simultanément plusieurs tests d'hypothèses. Dans le premier chapitre, nous faisons un rappel sur les notions de base de l'inférence statistique à savoir l'estimation ponctuelle et par intervalle. Dans le deuxième chapitre, nous abordons la théorie de l'estimation par intervalle de confiance bayésien décrit dans [10]. Des résultats nouveaux sont présentés dans ce chapitre. Des travaux partiels (voir [7]), montrent que la probabilité de recouvrement fréquentiste est faible aux frontières de l'intervalle. Comparé à ces derniers, nous avons montré sous certaines conditions que cette probabilité n'ira jamais au delà d'une borne supérieure qui semble éloignée de la crédibilité. Finalement, au Chapitre 4, nous traitons des estimateurs de la probabilité de fausses découvertes. Des améliorations significatives ont été faites dans ce cadre.

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.
