Abstract

fetched live from OpenAlex

Let K be a convex set in R d and let K $\\lambda$ be the convex hull of a\nhomogeneous Poisson point process P $\\lambda$ of intensity $\\lambda$ on K. When\nK is a simple polytope, we establish scaling limits as $\\lambda$ $\\rightarrow$\n$\\infty$ for the boundary of K $\\lambda$ in a vicinity of a vertex of K and we\ngive variance asymptotics for the volume and k-face functional of K $\\lambda$,\nk $\\in$ {0, 1, ..., d -- 1}, resolving an open question posed in [18]. The\nscaling limit of the boundary of K $\\lambda$ and the variance asymptotics are\ndescribed in terms of a germ-grain model consisting of cone-like grains pinned\nto the extreme points of a Poisson point process on R d--1 $\\times$ R having\nintensity $\\sqrt$ de dh dhdv.\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.
