Abstract

fetched live from OpenAlex

'Honeycrisp', une nouvelle variété de pommes, est susceptible à l'échaudure molle (ÉM) et au brunissement interne (BI). Des conditions froides à la fin du développement des pommes induiraient leur développement. Des 'Honeycrisp' ont été récoltées en Ontario (trois sites), au Québec (deux sites) et en Nouvelle-Écosse (un site), en 2009 et 2010, avec l'ajout de données de l'Ontario (quatre site) entre 2002 et 2006. Des analyses ont été faites pour lier la qualité des pommes aux conditions météorologiques. Une combinaison de conditions sèches (aux stades phénologiques BBCH 71-75) et de températures froides (BBCH 65-71 et 77.5-80) augmenterait l'incidence d'ÉM, alors que des conditions froides et de fortes précipitations (BBCH 77.5-80) intensifierait le BI. Deux modèles de prédiction ont été développés pour l'ÉM (RMSE = 18.71) et le BI (RMSE = 6.88). Ceux-ci peuvent servir d'outils aidant les producteurs à élaborer une stratégie de mise en marché appropriée, selon les conditions régionales et saisonnières.

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.
