Analysis plans for a child–adult human action recognition benchmark

Analysis plans of a study comparing action recognition accuracy on children and adults with a class-balanced, human-verified benchmark built from Kinetics-700. 1) Main analysis plan (dated 28 September 2026), with a change log that dates each later change and states whether it was made before or after the results. 2) Plan for two additional analyses (26 October 2026): more Kinetics-400 models used off the shelf, and partial fine-tuning of an image and a video backbone. The record contains no data about the people in the videos. Annotations and code will be deposited separately, with restricted access.
