Abstract

fetched live from OpenAlex

We have defined nonlinear correlations based on a superposition of simple linear correlation between binary images in order to control the discrimination capability in pattern recognition. The facility of optical system to perform linear correlation is the basic motivation. Moreover the binary information required allows the use of fast spatial light modulators working on binary regime. Particularly, in this paper we define a weighted nonlinear correlation named WSONG correlation, based on a correlation matrix representation. The procedure uses different diagonals for different recognition purposes. We have defined an amplitude of discrimination parameter as a function of the number of diagonals of the correlation matrix. The greater the tolerance, the higher number of correlation matrix diagonals involved in the process.

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.
