Model Card for SPA: 3D Spatial-Awareness Enables Effective Embodied Representation

Pre-trained checkpoints of SPA.

SPA is a novel representation learning framework that emphasizes the importance of 3D spatial awareness in embodied AI. It leverages differentiable neural rendering on multi-view images to endow a vanilla Vision Transformer (ViT) with intrinsic spatial understanding. We also present the most comprehensive evaluation of embodied representation learning to date, covering 268 tasks across 8 simulators with diverse policies in both single-task and language-conditioned multi-task scenarios.
