Abstract

fetched live from OpenAlex

This paper describes the use of the sequential slack algorithm to decode cyclic(or extended cyclic) block codes. Once a block code is endowed with a trellis structure decoding with any of the convolutional decoding algorithms is viable. Since trellises for block codes are very wide a sequential algorithm, working at moderate signal-to-noise ratios, is an ineffective decoding alternative to the Viterbi algorithm. Using Wolf's trellis, Chang and Yao's sequential stack algorithm and the Fano metric the (24,12) Golay code can be efficiently decoded. Computer simulations show that by 6 dB the sequential algorithm is the most efficient (using Be'ery and Snyders' definition of complexity) soft decoding algorithm for the (24,12) Golay code.

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.
