Abstract

fetched live from OpenAlex

筆者らは2000年、拡張Hensel構成の初期因子を多項式とすることで、従変数の原点で主係数が0となり且つ従変数に関して疎な多変数多項式の因数分解法を提案した。一般Hensel構成に基づく算法では従変数の原点移動が必要で、項数が増大して計算効率が著しく低下するが、筆者らの算法では原点移動は必要なく、計算効率の低下は避けられる。しかし、主変数に関して高次かつ疎な場合は依然として未解決だった。本稿では未解決点も含め算法を抜本的に改善する。従来の拡張Hensel構成算法は、一般Hensel構成と同様、Moses-Yun補間式を用いて構成を行う。拡張Hensel構成では、Moses-Yun補間式は従変数に関して有理式となり、計算に非常に時間がかかる。Hensel因子の計算も、有理式を扱うので複雑でしかも重い。本稿で提案する算法はMoses-Yun補間式を全く用いず、初期因子を生成元とするグレブナー基底を用いる。ただし、初期因子が3個以上の場合でも2個づつの組に分割して計算する。旧算法では、分母因子の候補は初期因子の終結式で、分子多項式と簡約されて小さな分母因子になるが、新しい算法では分母因子の候補はグレブナー基底の最小順位の多項式で、終結式より遥かに小さいので以後の計算が軽い。さらに、分母多項式をシステム記号で置き換え有理式を多項式化するので、計算が一層効率化される。まだ小規模な例題でテストしただけだが、テスト結果は非常によい。

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.
