Abstract

fetched live from OpenAlex

Adequately priced orders and time for fresh produce (FP) are two factors that bring commercial benefits to vendors and minimizes waste. However, many factors, such as income, labor, and other trade issues, affect the price that include uncertainties due to climate change, making decisions on FP procurement prices and quantities extremely challenging. Two artificial intelligence-based forecasting tools, i.e., a single variate and a multivariate model, are trained, tested, and compared in this study to predict future daily offer prices up to 7 days ahead for strawberries using mutual transactions for the distribution centers of Loblaws Companies Limited (LCL) in Canada. Results reveal that the developed multivariate model, utilizing both prices of the LCL dataset and California's strawberries yield dataset as predictors, outperforms the best single variate model.

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.
