La croissance des villes canadiennes et australiennes guidée par le hasard ? Enjeux et mesure de la croissance aléatoire urbaine
Bibliographic record
Abstract
Cet article apporte des éclaircissements quant à l’existence d’une croissance urbaine aléatoire pour les cas Canadien et Australien. La détection de ces processus passe par un approfondissement du protocole de test en distinguant trois spécifications : marche aléatoire pure, avec dérive, et avec dérive et tendance. L’article démontre que la croissance urbaine comporte effectivement une dimension aléatoire. Les petites aires urbaines y sont plus sensibles et leur croissance dépend exclusivement de chocs. Les grandes aires urbaines et celles qui détiennent des activités économiques métropolitaines, croissent sous l’effet d’une tendance déterministe diluant l’effet des chocs, les rendant moins fragiles.

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.
