Abstract
Salt is one of the commodities in Indonesia.Salt has a very strategic and sustainable role for human life.Apart from being used for daily consumption, salt is also used as a raw material for various industries Indonesia, as a country surrounded by coastlines, can be self-sufficient in salt production and meet domestic salt needs.However, not all the salt produced maintains sufficient quality for consumption.Therefore, monitoring of the produced salt's quality is necessary to categorize it.Even though the categorization of salt quality is still carried out manually, this research employs data mining techniques with three different algorithms: Naï ve Bayes, K-Nearest Neighbor (K-NN), and Support Vector Machine (SVM), to simplify and enhance the efficiency of the classification process.The dataset used was obtained from salt data in the Sumenep region of Madura that consists of 349 records with seven attributes: sulfate, magnesium, water content, calcium, not dissolved, NaCl(wb), and NaCl(db) with four data classes that represent grades of salt quality (K1, K2, K3, and K4), and the salt data is divided into training and testing sets using the k-fold cross-validation method.Test results indicate that the K-NN method provides better outcomes compared to other methods, with an AUC value reaching 99.0%, accuracy of 91.7%, F1 Score reaching 91.6%, precision of around 91.9%, and recall of around 91.7%.

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
