Abstract

fetched live from OpenAlex

Les systèmes à commutation représentent une classe particulière de systèmes hybrides. Ils sont décrits par plusieurs modèles de fonctionnement et chaque modèle, définissant un mode du système, est actif sous certaines conditions opératoires particulières. Lorsque la loi de commutation régissant le passage d'un modèle de fonctionnement à l'autre est parfaitement connue, il est aisé de manipuler de tels systèmes car le mode actif peut être connu à chaque instant. Par contre, dans la situation où aucune information n'est disponible sur l'évolution de la loi de commutation, il est plus ardu de procéder au diagnostic ou encore de synthétiser une loi de commande sur ces systèmes. Cet article traite de la reconnaissance du mode actif sur la base d'observations de l'entrée et de la sortie du système. L'identification des paramètres de la loi de commutation lorsque celle-ci est décrite par un modèle de régression, est également abordée.

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.
