Abstract

fetched live from OpenAlex

Abstract The kappa statistic is a widely used measure for quantifying agreement between raters using nominal scales. It is advocated on the grounds that it “corrects” for a level of agreement that would be expected by chance alone based on the marginal rates. The operating characteristics of kappa, however, show that it responds in a complicated and unintuitive way to subject‐specific and marginal agreement. Modifications to kappa and supplementary statistics, which have been proposed to help interpret kappa are discussed. Remarks are made as to why the kappa statistic has such problematic features.

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.
