Abstract

fetched live from OpenAlex

Alarms systems provide important alerts for the safety and efficiency of industrial facilities. However, due to complex plant connectivity and interconnections of process variables, there exist many alarms that are correlated with each other, leading to compromised alarm system performance in indicating the exact abnormality. Therefore, a systematic method to discover correlated alarms from historical Alarm & Event (A&E) logs is proposed in this work. The contributions of this study are twofold: 1) Correlated alarms are captured using a pattern mining approach, such that alarm occurrence orders are preserved to help root cause analysis; 2) network graphs are generated to visualize alarm correlations and their statistical features as indications of potential abnormality propagation paths. The effectiveness of the proposed method is demonstrated via case studies using alarm data from real industrial facilities.

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.
