Abstract

fetched live from OpenAlex

The Conditional Preference Network (CP-net) is a graphical tool for representing and reasoning about user's conditional ceteris paribus preference statements. In case the user provides partial preferences, we get a partial CP-net. In this paper, we propose a novel algorithm, that we call Search-Partial-CP, to find the Pareto optimal outcomes with respect to an acyclic partial CP-net and a set of hard constraints. Search-Partial-CP is a backtrack search algorithm that utilizes the topological order of the related Directed Acyclic Graph (DAG) to order the variables, as well as the topological order of the partial preferences to order the values, during the instantiation process. Search-Partial-CP can significantly reduce the search space by pruning every infeasible or dominated outcome. We present and discuss the formal properties of Search-Partial-CP.

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.
