Abstract

fetched live from OpenAlex

L'identification de la saisonnalite des crues est une procedure dont les applications sont nombreuses en hydrologie et en gestion des ressources en eau. Plusieurs methodes statistiques pour caracteriser la saisonnalite des crues ont emerge lors de la derniere decennie. Neanmoins, jusqu'a present, l'attention a ete faiblement portee sur l'incertitude impliquee par l'utilisation de ces methodes, et sur la confiance de leurs estimations. Cet article compare les performances des modeles d'echantillonnage de maximum annuel (MA) et de depassement (D) pour l'estimation de la saisonnalite des crues. La saisonnalite est determinee par deux methodes frequemment utilisees, l'une basee sur les statistiques directionnelles (SD) et l'autre sur la distribution des frequences relatives mensuelles des occurrences de crues (FR). La performance est evaluee pour le modele MA et pour trois modeles D courants selon la methode d'estimation, le type de saisonnalite et la longueur de l'echantillon enregistre. Les resultats montrent que les modeles D surpassent le modele MA dans la plupart des scenarios analyses. L'echantillonnage D fournit une information sur la saisonnalite significativement plus importante que l'echantillonnage MA. Pour certains types de saisonnalite, les echantillons D peuvent engendrer une incertitude sur l'estimation jusqu'a dix fois plus longue que les echantillons MA. La performance de la methode FR ne depend pas autant de la saisonnalite que celle de la methode SD, qui presente de mauvaises performances lorsque l'on considere des echantillons generes avec des distributions de saisonnalite complexes.

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.
