Abstract

fetched live from OpenAlex

The Conditional Preference Network (CP-net) graphically represents user's qualitative and conditional preference statements under the ceteris paribus (all else being equal) interpretation. Given that the CP-net induces a partial order over the outcomes, the optimization for a constrained CP-net can have a set of Pareto optimal solutions. The existing algorithms for solving the constrained CP-net require dominance testing between the outcomes, which is a very expensive operation. In this paper, we propose an extension of the CP-net model by eliciting additional relative importance statements between variables in order to have a total order over the outcomes. As a result, the constrained optimization using the proposed model involves a single optimal solution, assuming the underlying CSP is consistent. In this regard, we provide an efficient algorithm to find this optimal solution without the need for dominance testing.

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.
