Abstract
<title>Abstract</title> <italic>Brassica rapa</italic> is an annual to biennial herb that is widely cultivated as a vegetable or oilseed crop. It has escaped and become weedy or invasive in cultivated fields and disturbed areas. In Oceania it is listed as an invasive in Australia, Fiji, New Caledonia and New Zealand. In North America it is listed as invasive in some areas of Canada and the USA. In USA, seed use is restricted in Arizona and Michigan. It is also listed as invasive in Cuba, Mexico, Nicaragua, Chile, Ecuador and Peru. There is limited information available about its invasiveness and how it affects habitats, but it has been reported that the species can displace desirable vegetation if not properly managed. In California, USA it establishes in disturbed areas and forms dense stands that can displace native vegetation. In Mexico, although <italic>B. rapa</italic> is a frequent species in disturbed areas, there are no conclusive data about its negative impact on natural habitats. Its low stature prevents <italic>B. rapa</italic> from shading other species, and as most of its growth occurs during the winter months and the rainy season it avoids competition with many native species.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
