Abstract

fetched live from OpenAlex

Dans notre imaginaire historique, la récente révolution numérique de la photographie a tendance à occulter une révolution antérieure qui fut moins totale mais plus profonde : la révolution analogique, c’est-à-dire la traduction d’images en signaux électriques et en champs magnétiques variant de façon continue. La photographie analogique électronique a pris la forme de la télévision et de la vidéo, mais aussi de techniques d’enregistrement d’images fixes (par exemple le Videofile d’Ampex dans les années 1960 ; le Mavica de Sony dans les années 1980). Les principaux composants de ces nouvelles technologies, notamment ceux utilisés par les procédés d’enregistrement haute-fidélité et les tubes à vide pour les caméras vidéo, ont d’abord été mis au point à des fins militaires. L’électronique analogique partageait ces éléments et beaucoup d’autres – notamment les supports physiques d’enregistrement – avec les technologies numériques. Peter Sachs Collopy nous montre donc que ce n’est pas la numérisation qui a radicalement transformé la photographie au siècle dernier, mais bien le remplacement de la photochimie par des supports électromagnétiques, à la fois analogiques et numériques.

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.
