Abstract

fetched live from OpenAlex

Dans le cadre d'une étude écologique intégrée, nous avons effectué une analyse et une classification des sols, dans la région du lac Abitibi, Québec. Soixante-neuf paramètres, provenant des analyses physico-chimiques de même que de la description du sol et du site d'échantillonnage, ont servi au calcul des similarités entre chacun des profils de sol. L'analyse en coordonnées principales a permis de dégager les relations entre les différents profils de sols. Ceux-ci varient principalement en fonction de la roche-mère pédologique, du drainage et de la richesse relative en bases. L'analyse par agglomération hiérarchique nous a permis de classifier chacun des sous-ensembles définis par la roche-mère pédologique. Cette classification a montré, a posteriori, une bonne corrélation avec le système canadien de classification des sols, bien qu'elle ne coïncide pas parfaitement avec les unités taxonomiques de celui-ci.

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.
