Abstract

fetched live from OpenAlex

Modifications to previous implementations of the Wigner (1932) distribution (WD) are proposed so that the cross terms disappear and the existing residuals, some of negative value, can be treated as minor noise introduced by quantization. Rather than dealing with the auto-WD of a given signal, the cross-WD is used in order to bypass the undesirable properties of the bilinear transformation. Examples are presented to compare the results to those obtained using the short-time discrete Fourier transform (STDFT). In each instance, the proposed method performed at least as well as the STDFT.>

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
