Abstract

fetched live from OpenAlex

Abstract A borderline case function f for Q α (ℝ n ) spaces is defined as a Haar wavelet decomposition, with the coefficients depending on a fixed parameter β &gt; 0. On its support I 0 = [0, 1] n , f ( x ) can be expressed by the binary expansions of the coordinates of x . In particular, f = f β ∈ Q α (ℝ n ) if and only if α &lt; β &lt; , while for β = α, it was shown by Yue and Dafni that f satisfies a John–Nirenberg inequality for Q α (ℝ n ). When β ≠ 1, f is a self-affine function. It is continuous almost everywhere and discontinuous at all dyadic points inside I 0 . In addition, it is not monotone along any coordinate direction in any small cube. When the parameter β ∈ (0, 1), f is onto from I 0 to , and the graph of f has a non-integer fractal dimension n + 1 − β .

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
