Abstract
In 2011 Matwin et al published a letter to JAMIA entitled ‘Performance of SVM and Bayesian classifiers on the systematic review classification task’.1 This letter continued a discussion on the relative benefits of using support vector machine (SVM) and Bayesian techniques for performing systematic reviews.2–4 In particular, it was suggested that the running time of algorithms must be taken into consideration when comparing their performances as it becomes very important for large datasets. Following up on this idea, we attempted to directly compare the performance of a Bayesian method with the SVM algorithm used by Cohen in his original work.4 The same SVM system (SVMlight5) with the same parameters as was …

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 it
