Abstract

fetched live from OpenAlex

L'identification de systèmes multivariables linéaires et invariants représentés sous forme de modèles d'état à temps continu à partir de données d'entrée/sortie échantillonnées est considérée au sein de cet article. L'approche développée repose sur l'association de deux techniques de filtrage et de deux algorithmes des sous-espaces. Les techniques de filtrage permettent de contourner le problème de dérivation des signaux inhérent à toute identification directe de modèles à temps continu. Les moments partiels réinitialisés et les filtres à variables d'état sont plus particulièrement employés. Les algorithmes des sous-espaces proposés sont quant à eux fondés sur la classe d'identification MOESP. Une attention particulière est prêtée au problème de construction de la variable instrumentale utilisée pour fournir une estimation fiable des matrices d'état dans un contexte bruité. Les performances des algorithmes développés ainsi que l'influence de certains paramètres de construction sont mises en évidence à l'aide d'un exemple de simulation.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
