Alternative approach for learning and improving the MCDA method PROAFTN
Bibliographic record
Abstract
The objectives of this paper are (1) to propose new techniques to learn and improve the multicriteria decision analysis (MCDA) method PROAFTN based on machine learning approaches and (2) to compare the performance of the developed methods with other well-known machine learning classification algorithms. The proposed learning methods consist of two stages: The first stage involves using the discretization techniques to obtain the required parameters for the PROAFTN method, and the second stage is the development of a new inductive approach to construct PROAFTN prototypes for classification. The comparative study is based on the generated classification accuracy of the algorithms on the data sets. For further robust analysis of the experiments, we used the Friedman statistical measure with the corresponding post hoc tests. The proposed approaches significantly improved the performance of the classification method PROAFTN. Based on the generated results on the same data sets, PROAFTN outperforms widely used classification algorithms. Furthermore, the method is simple, no preprocessing is required, and no loss of information during learning. © 2011 Wiley Periodicals, Inc.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
