Abstract

fetched live from OpenAlex

Results from enzyme‐linked immunosorbent assays (ELISA) and immunofluorescence (IF) tests for the detection of Clavibacter michiganensis subsp. sepedonicus in potato tissue were analysed to determine the variation that occurs when different analysts perform the test. Data generated in accredited laboratories from sets of proficiency panel samples were used for the analysis. Sensitivity and specificity for both the ELISA and IF tests were very high as very few false positive and false negative results occurred. Analysis of z‐scores for the positive samples in the proficiency panel sets showed, for both serological tests, that about 90% of the results were within the acceptable range around the assigned values for the samples. Rescaled sum of scores for individual analysts who had false positive or negative results in ELISA were generally outside the acceptable range, although most analysts with high or low rescaled sums of z‐scores still identified each sample correctly as being positive or negative for the ring‐rot pathogen. For IF there were no false positive results, and the false negative results were not associated with aberrant rescaled sums of z‐score for the analysts, suggesting that perhaps an error in testing occurred rather than a problem with quantifying cell numbers.

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.
