ActorShift is a dataset where the domain shift comes from the change in actor species: we use humans in the source domain and animals in the target domain. This causes large variances in the appearance and motion of activities. For the corresponding dataset we select 1,305 videos of 7 human activity classes from Kinetics-700 as the source domain: sleeping, watching tv, eating, drinking, swimming, running and opening a door. For the target domain we collect 200 videos from YouTube of animals performing the same activities. We divide them into 35 videos for training (5 per class) and 165 for evaluation. The target domain data is scarce, meaning there is the additional challenge of adapting to the target domain with few unlabeled examples.
