Abstract

fetched live from OpenAlex

Dans le cadre du traitement STAP, une modélisation autorégressive (AR) des
\ninterférences utilisée avec un détecteur appelé Parametric Adaptive Matched Filter (PAMF)
\ndonne lieu à un filtre de réjection du fouillis pour lequel le domaine d’entraînement est réduit.
\nLa principale difficulté de cette approche réside alors dans l’estimation des matrices AR à
\nl’aide des données d’entraînement. Dans cette publication, les auteurs proposent une
\nestimation récursive fondée sur un filtrage de Kalman et ses variantes. Une étude
\ncomparative des différentes méthodes est menée sur les données fournies par la DGA –
\nMaîtrise de l’Information.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
