Abstract
Abstract We investigate a space‐filling criterion based on ‐type discrepancies, namely the uniform projection criterion, aiming at improving designs' two‐dimensional projection uniformity. Under a general reproducing kernel, we establish a formula for the uniform projection criterion function, which builds a connection between rows and columns of the design. For the commonly used discrepancies, we further use this formula to represent the two‐dimensional projection uniformity in terms of the ‐distances of U‐type designs. These results generalize existing works and reveal new links between the two seemingly unrelated criteria of projection uniformity and the maximin ‐distance for U‐type designs. We also apply the obtained results to study several families of space‐filling designs with appealing projection uniformity. Because of good projected space‐filling properties, these designs are well adapted for computer experiments, especially for the case where not all the input factors are active.

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
