World Action Models (WAMs) enable generalist robot manipulation by conditioning an action expert on representations from a pretrained video Diffusion Transformer (DiT). In closed-loop control, the video DiT runs at every chunk to encode the current observation into layerwise key-value (KV) pairs that the action expert...

This paper introduces PDE-JEPA for parametric PDE dynamics, and develops a physics-structured latent predictor that decomposes the dynamics into parameter-independent evolution and parameter-dependent response components.

The Edge-Conditioned Spectral Operator (ESO) is proposed, a novel spectral operator framework that modulates global spectral mixing using local edge-wise variations and preserves the global approximation capability of spectral neural operators while enabling the learned kernel to adapt to physics-sensitive local struct...
Direct latent-to-4D generation is introduced and instantiate it as Latent-to-4D, which bypasses RGB by aligning a video latent with the token grid of a pretrained 4D decoder and refining it through frame-wise and global spatiotemporal attention.
