Variable-Length Insertion-Based Noisy Sorting
Bibliographic record
Abstract
In this work, we study the problem of sorting n elements with pairwise comparisons under the presence of observation noise. We consider variable-length algorithms with a random number of queries M, and attempt to characterize the noisy sorting capacity defined as the maximal ratio $\frac{{n\log n}}{{{\text{E}}[M]}}$ such that the ordering can be correctly estimated with a vanishing error probability. This can be viewed as a generalization of the framework introduced in [1] to allow variable-length algorithms. We provide upper and lower bounds for the noisy sorting capacity. The proposed algorithm attaining the lower bound is based on the insertion sort algorithm for the sorting problem in the noiseless case and the variable-length version of the Burnashev–Zigangirov algorithm for coding over channels with feedback. Moreover, we also derive an upper bound on the maximal ratio that can be achieved by noisy sorting algorithms that are based on insertion sort.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
