Abstract

fetched live from OpenAlex

A real discrete Gabor expansion (RDGE) for finite and infinite sequences is defined in this paper. By replacing the complex Gabor basis functions of the complex discrete Gabor expansion (CDGE) with real Gabor basis functions, a significant computation of the RDGE can be saved as compared with the computation of the CDGE. The similarity between the RDGE and the discrete Hartley transform (DHT) allows the RDGE to utilize the fast DHT algorithms for fast computation. In addition, the RDGE has a simple relationship with the CDGE such that the CDGE coefficients can be directly computed from the RDGE coefficients. Some simulation results are given at the end of this paper.

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.
