Abstract

fetched live from OpenAlex

Evolution strategies and gradient strategies are two different approaches to continuous optimization. Salomon's evolutionary gradient search procedure is a hybrid strategy that obtains gradient estimates by borrowing the idea of random variations from evolutionary computation. The present paper applies successful tools and ideas from the theory of evolution strategies to the evolutionary gradient search framework. Performance and the influence of its parameters. Comparisons with the (/spl mu///spl mu/,/spl lambda/)-ES are presented, and the issue of genetic repair in evolutionary gradient search is discussed. The practically relevant problem of noisy objective function measurements is addressed, and recommendations with regard to the setting of strategy parameters are made.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
