Abstract

fetched live from OpenAlex

CP Rail has adopted a planned maintenance practice for freight car maintenance. The benefits accruing from planned maintenance, besides lower costs of car maintenance, are expected to be a reduction in car bad orders, elimination of the shopping of loaded cars, reduced car switching in terminals, improved car availability/utilization, and a reduction in car leasing. Implementation of the new policy has already commenced on the CP Rail coal-car fleet. The results have been a dramatic reduction in car bad orders and a consequent improvement in car availability. Implementation of planned maintenance on other car types in the CP Rail fleet is in progress.>

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.
