Anthropologic approach of bone age determination (accuracy of Greulich-Pyle method)
Bibliographic record
Abstract
Les objectifs de notre travail sur la maturation osseuse à partir d une radiographie de la région main-poignet sont la vérification de la validité de l Atlas de Greulich et Pyle (GP) appliquée à une population contemporaine, son amélioration dans une optique perspective médico-légale et l étude de l influence de certains facteurs environnementaux. Nous avons estimé l âge osseux de trois échantillons contemporains : 1372 individus marseillais, 263 enfants québécois et 645 enfants marocains. L atlas de GP, méthode de référence datant des années 1950, est toujours adapté à une population contemporaine. Son utilisation dans un cadre médico-légal doit intégrer la variabilité individuelle, source d imprécision incompressible, sous la forme d une fourchette d estimation que nous avons proposée dans un atlas revisité . La maturation osseuse est un marqueur anthropologique populationnel sous la dépendance de multiples facteurs notamment la corpulence mais aussi le niveau socio-économique.

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.
