Abstract

fetched live from OpenAlex

Genetic Algorithms (GAs) have been applied to matching problem. However, traditional GAs do not perform well in matching problem because there can be many locally similar parts. This paper presents a new genetic algorithm for silhouette matching. New concepts of partially matched genestrings in the initial population, the extending operator and the order adjustment algorithm are proposed. Each gene-string in the initial population only has three matched points while other points are unmatched. During the evolution, each gene-string will have more matched points due to the applications of the crossover and extending operators. The extending operator determines a potential match for an unmatched point near a matched point by searching the local space. After the application of the crossover and extending operators, the adjustment algorithm enforces each gene-string to be an ordered list by removing some matched points, if necessary. Our experiments show that the new matching algorithm based on GA performs better than traditional GA-based algorithms.

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.
