Abstract

fetched live from OpenAlex

Click to increase image sizeClick to decrease image size Additional informationNotes on contributorsErik TalvilaERIK TALVILA holds a B.Sc. from the University of Toronto, an M.Sc. from the University of Western Ontario and a Ph.D. from the University of Waterloo. After a visiting position at the University of Western Ontario and a postdoctoral fellowship at the University of Illinois in Urbana he is now at the University of Alberta. His main research interests are Henstock integration and its applications to harmonic functions, potential theory, and integral transforms. He spends his nonmathematical moments skiing and rock climbing (not simultaneously) and playing unusual board games.

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.
