Abstract

fetched live from OpenAlex

System identification using subspace-based methods has been a hot research topic in the past few years. Subspace methods fit state space models directly from the input and output signals measured from systems. In this paper we present a new way to identify a LTI system operating in a closed-loop experiment. One of the MOESP identification methods is adapted to identify the deterministic part of system operating in closed-loop experiment with nonwhite process noise and white output noise. A state space model will be computed to provide the relationship between the input and output of the plant. A simulation example is also provided to show how the algorithm works.

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.
