Abstract

fetched live from OpenAlex

SummaryConverting a matrix from row-order storage to column-order storage involves permuting the entries of the matrix. How can we determine this permutation given only the size of the matrix? Unexpectedly, the solution to this question involves the use of elementary group theory and number theory. This includes the Chinese remainder theorem, finding multiplicative generators modulo pn for prime p, and using these to find orbit generators for a group action, a subgroup of ℤN* acting on all of ℤN.

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.
