Abstract

fetched live from OpenAlex

The middle product computes the middle n terms of a (2 n --1)xn polynomial product, with effectively the same cost as computing an n x n polynomial product. The middle product allows for faster power series operations and Newton iteration. Middle product variants of classical, Karatsuba, and FFT-based multiplication algorithms are known. We present a middle product algorithm based on the Truncated Fourier Transform.

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.
