Abstract

fetched live from OpenAlex

Supervisory control is a formal method for the control of Discrete Event Systems (DES). The benefit of using supervisory control is that it allows the use of Modelling & Simulation (M&S) techniques to model an application and then use the model to create controllers. The use of supervisory control is currently restricted to robotics due to the issue of state space explosion as model size increases. Reduction in the state space complexity can expand the practicality of the model. We use the Discrete Event System Specifications (DEVS) formalism to implement supervisory control with an approximate method that reduces the state space complexity of the model. We also investigate the use of the hybrid layer to incorporate human interaction with a model and show that for certain cases a general approach can be used to reduce the complexity of the controller.

Full frame distilled prediction

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.
