Abstract

fetched live from OpenAlex

The paper presents an application of a GA algorithm to the optimization of terminal antennas, where the number of variables to optimize and the complexity of the problem could make standard GA approaches fail. This GA algorithm is based on the estimation of the density of probability of the highest fitness chromosomes in the population. This estimation is achieved by the use of dependency trees whose structure varies dynamically along the optimization process. A general overview of Bayesian networks and probability theory is presented. The algorithm based on dependency trees (TREE) is presented with some examples and compared to standard GA with dual population (DUAL) and with linkage crossover operator based GA (GLINX). The structure optimised is an antenna covering three frequency bands (GSM, DCS and UMTS), with one feed port for the two lower bands and another for the upper band. Convergence curves are presented for the three algorithms.

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.
