Abstract

fetched live from OpenAlex

The projected change in the market share of small vans in total light-duty vehicle sales, from the model year 1990 to 2010 based on the business-as-usual scenario is shown on this map. This scenario assumes that there are no major policy changes in the 1990 to 2010 period, which would affect vehicle preferences. Light-duty vehicles include all cars and light trucks. Over the forecasting period 1990 to 2010, there would be significant increases in the market share of small vans (about 16%) across Canada. The fastest growth in this vehicle market share would take place in the Atlantic Provinces.

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.

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.
