Aanbevolen Deense herkomsten van sitkaspar in Nederland
Bibliographic record
Abstract
Resultaten van een langlopend onderzoek naar de beste herkomsten van Sitkaspar voor Nederland. Sitkaspar komt van nature voor in een smalle zone langs de westkust van de VS en Canada. In Nederland is de soort op kleine schaal aangeplant, en in geval van verjonging is het van belang materiaal te gebruiken dat zo goed mogelijk is aangepast aan de Nederlandse ecologische omstandigheden. In het herkomstonderzoek zijn herkomsten uit Noord-Amerika en Denemarken vergeleken op eigenschappen als groei, stamvorm, laat uitlopen en slagingspercentage. Vier Deense herkomsten (uit drie zaadopstanden en een zaadgaard) worden vanwege hun kwaliteit opgenomen in de aanbevelende Rassenlijst voor Bomen. Alterra-rapport 846: Internationaal herkomstonderzoek Sitkaspar in Nederland, 2003

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.
