Abstract

fetched live from OpenAlex

A full set of numerical wave number k that includes imaginary part as function of frequency can now be obtained by a simple procedure which does not involve numerical root-finding scheme. FFT computation and data storage for the entire time sequence of all fields along the grids can also be avoided by approximating frequency domain inverse transform. The results of the initial numerical simulation are encouraging but are limited by the numbers of terms in the derivative expansions. Other numerical approximations are being investigated and these will be the focus of the presentation.

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.

Full frame distilled prediction

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.
