Abstract
When approximating dynamic systems with Laguerre basis functions (LBFs) it is important to tune the Laguerre pole such that the expansion can be both parsimonious and accurate. Expressing the sum of squared errors (SSE) as a function of the Laguerre pole leads to an objective function that has many local minima and therefore cannot be optimized directly. Two alternative methods have been proposed in the literature: an asymptotically optimal method, and the enforced convergence criterion (ECC). In this paper, a generalization of the ECC will be investigated such that in the limit minimizing this generalized ECC and computing the asymptotically optimal solution lead to the same Laguerre pole. Moreover, it will be proved that these generalized ECCs are quasiconvex functions which means they can be efficiently minimized using numerical optimization techniques. The concept of operator quasiconvexity is investigated and used to prove quasiconvexity of the ECC.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
