Abstract

fetched live from OpenAlex

A direct proof is given for Akiyama and Tanigawa's algorithm for computing Bernoulli numbers. The proof uses a closed formula for Bernoulli numbers expressed in terms of Stirling numbers. The outcome of the same algorithm with di#erent initial values is also briefly discussed. 1 The Algorithm In their study of values at non-positive integer arguments of multiple zeta functions, S. Akiyama and Y. Tanigawa [1] found as a special case an amusing algorithm for computing Bernoulli numbers in a manner similar to "Pascal's triangle" for binomial coe#cients. Their algorithm reads as follows: Start with the 0-th row 1, 1 2 , 1 3 , 1 4 , 1 5 , . . . and define the first row by 1 (1 - 1 2 ), 2 ( 1 2 - 1 3 ), 3 ( 1 3 - 1 4 ), . . . which produces the sequence 1 2 , 1 3 , 1 4 , . . . . Then define the next row by 1 ( 1 2 - 1 3 ), 2 ( 1 3 - 1 4 ), 3 ( 1 4 - 1 5 ), . . . , thus giving 1 6 , 1 6 , 3 20 , . . . as the second row. In general...

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
