Abstract

fetched live from OpenAlex

In this paper we give an efficient algorithm for computation of order basis of a matrix of power series. For a problem with an m x n input matrix over a field K, m ≤ n, and order σ, our algorithm uses O(MM(n, ⊂O~(nω⌈mσ/n⌉) field operations in B.K, where the soft-O notation O~ is Big O with log factors omitted and MM(n,d) denotes the cost of multiplying two polynomial matrices with dimension n and degree d. The algorithm extends earlier work of Storjohann, whose method can be used to find a subset of an order basis that is within a specified degree bound δ using O~(MM(n,δ)) field operations for δ≥⌈ mσ/n⌉.

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.
