Abstract

fetched live from OpenAlex

Abstract We show that any finite family of pairwise intersecting balls in can be pierced by points improving the previously known estimate of . As a corollary, this implies that any 2‐illuminable spiky ball in can be illuminated by directions. For the illumination number of convex spiky balls, that is, cap bodies, we show an upper bound in terms of the sizes of certain related spherical codes and coverings. For large dimensions, this results in an upper bound of , which can be compared with the previous established only for the centrally symmetric cap bodies. We also prove the lower bounds of for the three problems above.

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.
