Parametrically prox-regular functions
Bibliographic record
Abstract
Prox-regularity is a generalization of convexity that includes all lower-C² functions. Therefore, the study of prox-regular functions provides insight on a broad spectrum of important functions. Parametrically prox-regular (para-prox-regular) functions are a further extension of this family, produced by adding a parameter. Such functions have been shown to play a key role in understanding the stability of minimizers in optimization problems. This thesis discusses para-prox-regular functions in ℝn. We begin with some basic examples of para-prox-regular functions, and move on to the more complex examples of the convex and non-convex proximal averages. We develop an alternate representation of para-prox-regular functions, related to the monotonicity of an f-attentive ε-localization as was done for prox-regular functions [25]. Levy in [18] provided proof of one implication of this relationship; we provide a characterization. We analyze two common forms of parametrized functions that appear in optimization: finite parametrized sum of functions, and finite parametrized max of functions. The example of strongly amenable functions by Poliquin and Rockafellar [27] is given, and a relaxation of its necessary conditions is presented. Some open questions and directions of further research are stated.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
