Predictive Fuzzy Control of Paper Quality
Bibliographic record
Abstract
Pulp and paper quality depends on the quality of wood chips which depends on their physical and optical properties. Presently, there is no formally established knowledge concerning the co-influences of the several parameters governing the thermo-mechanical pulp and paper process (TMP). The main goal of this paper is to automatically generate fuzzy knowledge bases (FKBs) to characterize wood chip properties online and apply this information to optimize the TMP process so that pulp quality can be predicted and controlled using wood chip properties (defined by numerical data). The production settings used in this article take into account the hydrosulfite bleaching agent. Learning of the FKBs (using a genetic algorithm) uses measurements obtained from the chip management system (CMSreg). Changes in chip quality are measured by physical information (color analysis and humidity) using CMSreg. The information provided by CMSreg enabled us to predict the ISO brightness of the produced pulp according to a certain charge of hydrosulfite. The developed FKBs are used afterwards to control the optimal hydrosulfite charges using a Monte-Carlo based search algorithm

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.
