Abstract

fetched live from OpenAlex

The edit distance between two strings is the minimal number of substitutions, deletions, or insertions required to transform one string into another. An error correcting code over the edit metric includes features from deletion-correcting codes as well as the more traditional codes defined using Hamming distance. Applications of edit metric codes include the creation of robust tags over the DNA alphabet. This paper explores the theory underlying edit metric codes for small alphabets. The size of a sphere about a word is heavily dependent on its block structure, or its partition into maximal subwords of a single symbol. This creates a substantial divergence from the theory for the Hamming metric. An optimal code is one with the maximum possible number of codewords for its length and minimum distance. We provide tables of bounds on code sizes for edit codes with short length and small alphabets. We describe issues relating to exhaustive searches and present several heuristics for constructing codes

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.
