Abstract

fetched live from OpenAlex

Copulas are very applicable tools from a statistical point of view. Their capability to model joint distribution makes them a useful tool for statisticians. Yet, they have been applied rarely in multi-criteria decision aiding (MCDA). This paper introduces a novel family of aggregation functions based on 2-copulas for MCDA. More specifically, the proposed copula-based method is applied to construct the popular Choquet integral (CI) and attitudinal Choquet integral (ACI). The forms obtained are utilized to develop a machine learning model to explain choices in the human decision-making situations. Exemplary pairwise preferences are provided as training information for the proposed model. Our approach effectively represents the dependencies between criteria under uncertainty. Experimental results on multiple real-world datasets demonstrate that our approach significantly outperforms popular MCDA methods, such as RBF-kernel, Tchebycheff, etc.

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.
