Abstract
In this paper, we introduce a natural generalization of Weighted Set Cover and Maximum Coverage, called Size-Constrained Weighted Set Cover. The input is a collection of n elements, a collection of weighted sets over the elements, a size constraint k, and a minimum coverage fraction ŝ; the output is a sub-collection of up to k sets whose union contains at least ŝn elements and whose sum of weights is minimal. We prove the hardness of approximation of this problem, and we present efficient approximation algorithms with provable quality guarantees that are the best possible. In many applications, the elements are data records, and the set collection to choose from is derived from combinations (patterns) of attribute values. We provide optimization techniques for this special case. Finally, we experimentally demonstrate the effectiveness and efficiency of our solutions.

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
