Abstract
Perturbation-based extremum seeking (ES) is a non model-based approach to maximize or minimize the output of a dynamic system without requiring any explicit information about the dynamics of the system, steady state map, or the value of the extremum. In this work, perturbation-based ES is used to minimize power reflection from a cavity resonator in order to provide maximum accelerating field for particles travelling through the cavity. Power reflection is minimized by equalizing the frequency of the cavity and RF source. The controller sends commands to a step motor setup connected to the cavity. The step motor moves the tuner plate which changes the frequency of the cavity. Simulation and experimental results are presented which indicate that the algorithm can successfully minimize power reflection despite variations in the value of the minimum.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
