Abstract

fetched live from OpenAlex

In this paper, we study a proximal-like algorithm for minimizing a closed proper function f(x) subject to x ‚ 0, based on the iterative scheme: x 2 argminff(x)+ kd(x;x ki1 )g, where d(¢;¢) is an entropy-like distance function. The algorithm is well- deflned under the assumption that the problem has a nonempty and bounded solution set. If, in addition, f is a difierentiable quasi-convex function (or f is a difierentiable function which is homogeneous with respect to a solution), we show that the sequence generated by the algorithm is convergent (or bounded), and furthermore, it converges to a solution of the problem (or every accumulation point is a solution of the problem) when the parameter k approaches to zero. Preliminary numerical results are also reported, which further verify the theoretical results obtained.

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.
