Occupational color vision standards: new prospects
Bibliographic record
Abstract
Occupational color vision standards in transport have been implemented for 100 years. A review of these standards has taken place early this century prompted by antidiscrimination laws in the workplace and several transport accidents. The Australian and Canadian Railways have developed new lanterns to address their occupational medical requirements. The Civil Aviation Authority in the UK has adopted the Color Assessment and Diagnosis (CAD) test as the standard for assessing color vision for professional flight crews. The methodology employed using the CAD test ensures that color deficient pilot applicants able to complete the most safety-critical task with the same accuracy as normal trichromats can be accepted for pilot training. This methodology can be extended for setting new color vision standards in other work environments.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
