Une source pollinique et son exploitation
Bibliographic record
Abstract
Résumé Le sondage de la tourbière de Glatinié, localisée au nord de la ville de Laval (Mayenne), a livré 2 m de sédiments qui révèlent l’évolution de la pression anthropique sur le milieu végétal depuis le Néolithique jusqu’à nos jours. Dès la base du diagramme pollinique (5035 ± 70 b.p.), les premières traces de céréales sont détectées. Durant l’âge du bronze, les coteaux environnants subissent une première phase de défrichement, mais il faut attendre le second âge du fer vers 2300-2400 b.p. pour enregistrer des activités agro-pastorales. Après une déprise agricole pendant le Bas-Empire, une recrudescence des pratiques culturales et d’élevage est marquée, corrélativement à un déboisement drastique qui aboutit à un milieu « ouvert ».
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.
How this classification was reachedexpand
Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
