Researchers have introduced SR-JEPA, a novel joint-embedding predictive architecture designed for 3D scene point clouds. This model learns by predicting latent representations of missing objects within a scene, rather than relying on reconstruction or semantic labels. Evaluations on the ARKitScenes dataset show that SR-JEPA can achieve 43.13% semantic-identity macro accuracy for imputed latent states, significantly outperforming baseline methods. Further experiments on Sr3D support pairs indicate the model infers a compositional 3D predictive state that can be combined with geometric information for downstream tasks. AI
