Supervised Block-Aware Factorization Machine for Multi-Block Quality-Relevant Monitoring
Bibliographic record
Abstract
Multi-block multivariate statistical methods have been developed to extract useful information from process and quality data in the era of big data, where process variables are partitioned into several meaningful blocks. However, most of these methods did not consider cross-correlations among divided blocks, which leads to inferior monitoring performance. In this article, a block-aware factorization machine (BAFM) algorithm is proposed to exploit information from process and quality data. In BAFM, quality data are first classified into normal and abnormal labels with principal component analysis based quality monitoring framework. Afterwards, a block number is attached to each process variable, and the interactions among different variables (both within and cross blocks) are learned through latent variables, which is supervised by the classified quality labels. Apart from the variable relation within the same block, BAFM also incorporates the block information; thus, both inner and cross correlations are constructed. The monitoring framework based on BAFM is developed, and its effectiveness and superiority are demonstrated through the Tennessee Eastman process.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
