Abstract

fetched live from OpenAlex

Cet article présente une solution de décodage par liste optimisée pour des vidéos corrompues par des erreurs de transmission. Elle est basée sur l’évaluation de la qualité des images sans référence utilisant un réseau de neurones convolutif (CNN) qui gère efficacement les distorsions non uniformes. À l’issue d’un processus de décodage par liste, nous évaluons la qualité de chaque image candidate générée (sans référence) afin de sélectionner la meilleure. Lorsque l’erreur de transmission se produit dans une image intra, notre architecture a une précision de décision de plus de 98% contre 46% pour l’architecture CNN originale pré-entraînée. Pour les erreurs dans une image inter, c’est 79% contre 33%.

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.

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.
