Discriminant analysis of clinical color vision tests and color related tasks
Bibliographic record
Abstract
Purpose: Individuals with congenital color deficiencies show a large inter-observer variation in performing color related tasks. One such task is interpreting color codes used in VDT displays. The aim of this study is to determine if Ishihara, HRR plates, Farnsworth D-15, Adams D-15 and CN Lantern can predict the performance on a VDT color naming task. Methods: 100 color-normals and 52 color-defectives participated in the study. Pass/Fail criteria for the color naming task was established based on number and types of color normal errors. Results: Discriminant analysis was performed to compare the clinical tests with the task. HRR plates, Farnsworth D-15, Adams D-15 and CN Lantern were significant predictors according to the model. Of all the clinical tests, the Farnsworth D-15 test was the best predictor of performance on the practical test. The sensitivity and specificity was 0.75 and 0.92 respectively. Conclusions: Certain clinical tests are reasonable predictors for determining who can adequately identify certain VDT colors. These tests are generally used to diagnose moderate to severe color vision defects. The Farnsworth- D-15 test was the best predictor of the practical test. However, it was not perfect. Whether the Farnsworth- D-15 is sufficient for occupational purposes depends on the critical safety issues.

Full frame distilled prediction
Teacher imitationNot 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.
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 teacher head, not a consensus.
