Abstract

fetched live from OpenAlex

A subdivision scheme based on 4 points with Hermite data (function and first derivatives) on ZZ is studied. For a large region in the parameter space, the scheme is C 1 C1 convergent or at least is convergent in the space of Schwartz distributions. The Fourier transform of any interpolating function can be computed through products of matrices of order 2. The main tools for proving these results are the Paley-Wiener-Schwartz theorem on the characterization of the Fourier transforms of distributions with compact support, and a theorem of Heil-Colella about the convergence of some products of matrices.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
