Abstract

fetched live from OpenAlex

CPL1.0 is a Matlab code which can generate fault predictions of Tennessee Eastman (TE) process, based on the open-source toolbox developed by Kevin Murphy in 2005. It facilitates the calculation of Prior Probabilities (PP), Conditional Probabilities (CP), and Likelihood Evidence (LE). These are essential features required for fault prognosis purpose using Hidden Markov Model (HMM) and Bayesian Network (BN) hybrid model. Determination of the CP, PP, and LE is the most time-consuming component in the aforementioned process. The proposed code has the potential to drastically reduce the repetitive computation time thus enabling the researcher to focus on the main goal-oriented outcome. CPL1.0 is implemented as a facilitator to communicate between BN and the HMM in a hybrid fault prediction and prognosis system. The hybrid system can predict ten out of ten selected faults and can accurately prognose eight out of the ten faults.

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.
