New JEPA framework enhances control for partial differential equations

Researchers have developed a novel goal-agnostic control framework for partial differential equations (PDEs) utilizing a joint-embedding predictive architecture (JEPA). This framework trains a small ViT encoder and action-conditioned latent dynamics offline without specific goals, then freezes them for use by a model-predictive path integral (MPPI) controller. The study found that applying control objectives to explicit physical observables, rather than minimizing raw Euclidean distance in the latent space, yielded superior results. Specifically, on the PDE Control Gym 2D Navier--Stokes benchmark, this approach improved the matched reward and reduced velocity-field RMSE, demonstrating significant gains in controlling complex systems.
