Abstract
Coarsening phase is the most critical step among procedures in multilevel clustering algorithm. Some classi cal multilevel clustering algorithms, such as METIS (multilevel scheme for partitioning irregular graphs) and Graclus, use some criterions of vertex and edge weights to capture the collapsing of the vertex and edges and realize coarsening procedure. But there is the disadvantage that the coarsest dataset can not formulate the global information and struc ture of original dataset correctly. This paper proposes a core-sets coarsening method, which defines multilevel coresets to retain global information of layered dataset in perspective. Meanwhile, as the coarsest dataset has the same num ber as clustering, and each core point corresponds to a single class, the partitioning procedure need not be considered. Some numerical experiments verify the superiority and availability of the proposed algorithm.

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
