Abstract

fetched live from OpenAlex

The Julia function isf aims at listing the chambers of a hyperplane arrangement. By listing, we mean identifying the sign vectors corresponding to each of the (nonempty) chambers. Several variants of a main algorithm are available, defined by different parameters that can be changed and tuned. This code extends the Matlab solver isf.m, which is restricted to central arrangements. In this case, this problem has many equivalent reformulations that can thus be also dealt with by processing the output.

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.
