Abstract

fetched live from OpenAlex

Let $ϕ$ be a function that maps any non-empty subset $A$ of $\mathbb{R}^2$ to a non-empty subset $ϕ(A)$ of $\mathbb{R}^2$. A $ϕ$-cover of a set $T=\{T_1, T_2, \dots, T_m\}$ of pairwise non-crossing trees in the plane is a set of pairwise disjoint connected regions such that each tree $T_i$ is contained in some region of the cover, and each region of the cover is either (1) $ϕ(T_i)$ for some $i$, or (2) $ϕ(A \cup B)$, where $A$ and $B$ are constructed by either (1) or (2), and $A \cap B \neq \emptyset$. We present two properties for the function $ϕ$ that make the $ϕ$-cover well-defined. Examples for such functions $ϕ$ are the convex hull and the axis-aligned bounding box. For both of these functions $ϕ$, we show that the $ϕ$-cover can be computed in $O(n\log^2n)$ time, where $n$ is the total number of vertices of the trees in $T$.

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.
