Abstract

fetched live from OpenAlex

Statistical process control is a technique to monitor product or service quality timely that ensure stability. It promotes quality assurance, resource optimization, and is crucial to informed decision-making. Given the diversification of quality indicators, this paper introduces a multivariate EWMA control chart model based on the CRITIC and entropy weighting method. This model allows lack of knowledge of variable distributions and considers variable correlations, which demonstrates strong sensitivity to slight drifts in mean and volatility, even with a non-diagonal covariance matrix. Simulation experiments confirm its ability to identify process changes and their types by manipulating the mean vector and covariance matrix in five controlled experiments.

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.
