Abstract

fetched live from OpenAlex

ABSTRACT This note defines distributionally conservative versions of stochastic dominance relations based on subsampling. It presents a non‐asymptotic analysis of the probability of the false dominance (FD) error for the empirical version of the subsampling‐based empirical dominance procedure. The analysis is based on the generalization of the McDiarmid's concentration inequality to ‐mixing processes by Kontorovich and Ramanan. The concentration bounds obtained depend on the entropy characteristics of the problem, such as the Lipschitz coefficients of the utilities involved, the FD parameters involved, and the coefficients that represent temporal dependence at each subsample. The analysis establishes tighter concentration bounds for the conservative procedure in both stationary and nonstationary cases when the subsampling rate is appropriately chosen.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
