Abstract
In this paper, we discuss a novel statistical learning algorithm that predicts normal flows of process data in a distributed control system, i.e., process data evolutions that characterise the normal behaviour of a cyber-physical system such as a power plant. The algorithm’s prediction capability allows for determining whether the payload of a network packet that is about to be processed by a computer device in a distributed control system is normal or malicious. This classification is based on whether or not the process data evolution that a network packet under inspection has potential to cause is predicted as normal by the algorithm. In this paper, we also discuss a probabilistic validation of the algorithm. We construct stochastic activity networks with activity-marking oriented reward structures that model pertinent aspects of the normal operation of a cyber-physical system as a whole as perceived by the algorithm. The solution of these models via a tool such as Mőbius indicates whether the algorithm’s perception of normalcy is correct. We have implemented the algorithm in the MATLAB programming language, and thus in the paper we also discuss practical testing and evaluation of the effectiveness of the algorithm in a testbed that resembles a power plant.

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
