Abstract

fetched live from OpenAlex

L’introduction et la pénétration des appareils mobiles à la fin de la première décennie des années 2000 ont agi comme un élément déclencheur d’une révolution attendue du secteur du commerce de détail. La part des ventes en ligne américaines sur l’ensemble des ventes au détail atteignait près de 10 % (9, 8 %) en 2018 et devrait s’élever à 15, 1 % en 2022. Les ventes en ligne canadiennes suivent une progression semblable. Elles totalisaient 9, 2 % des ventes au détail en 2018 et devraient se hisser à 15, 3 % en 2022. La progression des ventes en ligne de produits alimentaires affiche un décalage en comparaison au portrait de l’ensemble du secteur commerce de détail. Les ventes en ligne américaines de produits alimentaires et d’alcool capturaient 1, 8 % des achats alimentaires en 2018 et devraient croître à 4, 4 % en 2020. Puisque le marché canadien suit les tendances américaines, cette croissance de la part des achats alimentaires effectués en ligne accélérera les changements dans les pratiques courantes des acteurs des secteurs bioalimentaire et de la distribution. Ce rapport analyse les enjeux qui découlent de cette transformation pour les acteurs de cette chaîne de valeur, notamment les manufacturiers agroalimentaires.

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.
