Abstract

fetched live from OpenAlex

Bandit problems with continuous set of arms arise in many settings. Of particular interest for this workshop are the cases of on-line parameter tuning or optimization of controllers based on simulations. We formalize the problem as follows. We consider an arbitrary set X (we do not talk about measurability issues in this extended abstract), whose elements will be referred to as arms. A decision maker “pulls”

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.
