All datasets are encoded by the same unsupervised body-motion encoder and projected into one shared t-SNE space. (a) Global projection with balanced sampled points per dataset. (b) Support-envelope comparison between HiPHI and BONES-SEED, the closest large-scale baseline; HiPHI’s support nearly encloses BONES-SEED. (c) Grid-based local-coverage statistics on the same embedding using a 55×55 grid.
