Abstract
A BRIEF HISTORY OF THE USDA MOTION PICTURE SERVICE TO 1943 The US Department of Agriculture (USDA) began producing films in the early 1900s and continued for decades. Millions saw these films in a wide variety of venues, including public schools, colleges and universities, civic meeting halls, libraries, church halls, and even open fields. Over the period of several decades, from the silent-movie era through the 1950s, the USDA was a significant government filmmaking organization, touting itself to be not only the first government agency to organize a filmmaking division but also the most prolific. The USDA motion picture branch was internationally respected, and the distribution of its films was high for US government institutions, particularly in the 1920s and 1930s. The USDA showed its films practically anywhere extension workers or others could gather a small group or a large crowd. The role of the films varied,...

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
