Abstract

fetched live from OpenAlex

The illumination number $I(K)$ of a convex body $K$ in Euclidean space\n$\\mathbb{E}^d$ is the smallest number of directions that completely illuminate\nthe boundary of a convex body. A cap body $K_c$ of a ball is the convex hull of\na Euclidean ball and a countable set of points outside the ball under the\ncondition that each segment connecting two of these points intersects the ball.\nThe main results of this paper are the sharp estimates $I(K_c)\\leq6$ for\ncentrally symmetric cap bodies of a ball in $\\mathbb{E}^3$, and $I(K_c)\\leq 8$\nfor unconditionally symmetric cap bodies of a ball in $\\mathbb{E}^4$.\n

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.
