Abstract
High Resolution Image Download MS PowerPoint Slide Advances in sensing technologies and AI have resulted in new in-line and online process measurements based on video, vibration, chromatograms, and other high-dimensional data that can complement common process measurements such as pressure, temperature, and flow rates. These sensors can be beneficial for process monitoring; however, their continuous use is often highly expensive or even impractical. In this work, we propose a novel fusion strategy to integrate insights from these sources when needed while predominantly relying on the less expensive common measurements. A hierarchical organization of sensors based on a generalized cost metric serves as the basis for the fusion. The fusion process intelligently utilizes the least expensive data first. Costlier data are used by the fusion scheme only if found necessary in real-time to improve performance. Through this lazy fusion strategy, heterogeneous multimodal sensors can be utilized within a unified framework to improve decision timeliness, accuracy, and reliability while being robust to data delays, sensor failures, and computational limitations. The proposed fusion technique has been tested on two case studies, a simulated CSTR process and an experimental data set obtained from a multiphase flow facility. The obtained results show a significant reduction in diagnostic delay compared to traditional process monitoring while utilizing costly video and high-frequency measurements only 15–30% of the time.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
