Abstract

fetched live from OpenAlex

In this paper we consider zero delay lossy coding schemes for individual sequences, and address the problem of tracking the best scalar quantizer which is adaptively matched to the sequence. The problem is an individual-sequence version of the problem of scalar quantization of piecewise stationary sources. A randomized algorithm is presented which can perform, on any source sequence, asymptotically as well as the best scalar quantization algorithm matched to the sequence which is allowed to change the employed quantizer from time to time. The complexity of the algorithm is quadratic in the sequence length. At the price of a slight deterioration of performance, the complexity can be made linear in the sequence length

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.
