Abstract

fetched live from OpenAlex

Les changements climatiques ont un impact sur l’ensemble des sphères de notre quotidien. L’agriculture est un domaine déjà affecté et le sera encore davantage dans les prochaines années. Les producteur.rice.s agricoles et toute la filière devront s’adapter à ces changements importants qui apporteront leur lot de nouveaux ennemis des cultures (insectes et maladies entre autres). Cela aura notamment des impacts sur les prises de décisions en matière de phytoprotection. Certains de ces ennemis sont indigènes au Québec, mais d’autres sont considérés comme des espèces exotiques envahissantes et seront susceptibles de provenir d’autres régions à travers le monde et de s’établir sous nos latitudes. Au cours des dernières années, le CÉROM, en collaboration avec OURANOS, le MAPAQ et Agriculture et Agroalimentaire Canada, a mené plusieurs projets visant à évaluer l’impact des changements climatiques sur les ennemis des grandes cultures. Dans cet article, quelques résultats de ces recherches sont présentés.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
