Abstract

fetched live from OpenAlex

This work deals with the computation of upper bounds on the gap metric and the corresponding stability margin. The suggested bounds can be computed for a class of a nonlinear systems which satisfy an inequality. Comparing to previous works, where results are highly dependent on the studied cases, our methods are applicable to a wider range of nonlinear systems. The results are based on two inequalities derived for the gap metric and the stability margin with respect to the gain of the relevant systems. An example is provided to illustrate the derived bounds for both our method and a previous method that is based on the direct computation.

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.
