Abstract

fetched live from OpenAlex

The objective of this dataset is to find out retail price differences between organic and conventional food items. Organic foods are often considered healthier and better quality than conventional foods and are sold at premium prices. However, first-hand data on retail price levels to substantiate that argument is meager. With a view to filling up that gap, we collected retail prices for pairs of conventional and organic food items in three supermarket chains (Save On Foods, Superstore, and Sobeys) in Edmonton, Alberta, for seven consecutive weeks in spring 2011. We find that the average prices significantly vary among supermarkets and among different food groups. Organic food prices show a different pattern than conventional food prices.

Full frame distilled prediction

Teacher imitation

Not 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.
