Abstract

fetched live from OpenAlex

In my thesis I was focused on the species spectrum of weeds in these crops – cabbage, pumpkins and potatoes. The observation was carried out in a company Zahradnictví Brabec located in Modřice, not far from Brno. I performed the evaluation on the basis of numerical method and statistics, using the ordination diagram to show the results. Most frequently in crops were Pigweed (Amaranthus retroflexus), Common lambsquarters (Chenopodium album) and Canada thistle (Cirsium arvense). These three weeds occured in all crops in large quantities. The most weeds were in pumpkin growthand the least weeds were in cabbage.

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.

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.
