Abstract

fetched live from OpenAlex

Computer scientists and software engineers seldom rely on using experimental methods despite frequent calls to do so. The problem may lie with the shortcomings of traditional experimental methods. We introduce a new form of experimental designs, synthetic designs, which address these shortcomings. Compared with classical experimental designs (between-subjects, within-subjects, and matched-subjects), synthetic designs can offer substantial reductions in sample sizes, cost, time and effort expended, increased statistical power, and fewer threats to validity (internal, external, and statistical conclusion). This new design is a variation of within-subjects design in which each system user serves in only a single treatment condition. System performance scores for all other treatment conditions are derived synthetically without repeated testing of each subject. This design, though not applicable in all situations, can be used in the development and testing of some computer systems provided that user behavior is unaffected by the version of computer system being used. We justify synthetic designs on three grounds: this design has been used successfully in the development of computerized mug shot systems, showing marked advantages over traditional designs; a detailed comparison with traditional designs showing their advantages on 17 of the 18 criteria considered; and an assessment showing these designs satisfy all the requirements of true experiments (albeit in a novel way).

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.
