Abstract

fetched live from OpenAlex

Restarts are a popular remedy to address (premature) convergence in metaheuristics. In Particle Swarm optimization, it has been observed that swarms often “stall” as opposed to “converge”. A stall occurs when all of the forward progress that could occur is instead rejected as failed exploration. Since the swarm is in a good region of the search space with the potential to make more progress, a (random) restart could be counter productive. We instead introduce a method to address the stall mechanism. The introduction of perturbations to the pbest positions leads to significant improvements in the performance of standard Particle Swarm optimization.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
