Abstract

fetched live from OpenAlex

The addition of a perturbed-energy term to the original cost functional of optimal singular control problems in order to avoid difficulties associated with computing singular controls is assessed via a direct search iterative dynamic programming procedure. The limitation of the strategy is shown from a computational point of view and some guidelines in the selection of the perturbation parameter is given using three examples. It is demonstrated that many gradient-based methods may not be particularly suited for computing singular sub-arcs when perturbation methods are used.

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.
