Abstract

fetched live from OpenAlex

We describe a Particle Swarm Optimization (PSO) approach to the problem of classifying mixed-attribute data sets. It relies on retrieving optimal particle positions in the search space that correspond to the centroids of classes. When evaluating the fitness function, we use different mechanisms to interpret the particle positions in the description space, based on data type; as will be described, rounding is used for integer attributes while a frequency measure is used for categorical descriptors. An experimental set up was realized and tested on the Adult database, leading to recognition accuracies that were better than those obtained with well known classifiers.

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.
