Why this work is in the frame

A frame that forgets how it found something cannot be audited. These are the routes that admitted this work.

venuePublished in a venue whose home country is Canada.
no affNo Canadian affiliation: this work is invisible to an affiliation-only frame.
No Canadian affiliation. An affiliation-only frame, the usual design, would never have seen this work. It is one of the works that make the case for inverting the frame.

Abstract

fetched live from OpenAlex

Coloring the Line Arnfried Kemnitz Computational Mathematics, Techn. Univ. Braunschweig, Pockelsstr. 14, 38 106 Braunschweig, Germany a.kemnitz@tu-bs.de The distance graph G(S, D) has vertex set V (G(S, D)) = S ⊆ IR and two vertices u and v are adjacent if and only if their distance d(u, v) is an element of the distance set D ⊆ IR+. We determine the chromatic index, the choice index, the total chromatic number and the total choice number of all distance graphs G(IR, D), G(Q, D) and G(ZZ, D) transferring a theorem of de Bruijn and Erdős on infinite graphs. Moreover, we prove that |D|+ 1 is an upper bound for the chromatic number and the choice number of G(S, D), S ⊆ IR.

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.
