This research paper proposes a novel approach to modeling partial differential equations (PDEs) using Conditional Neural Fields (NeFs). The authors leverage the strengths of NeFs, such as grid-agnosticity and space-time-continuous dynamics modeling, while also respecting known symmetries of the PDE. By preserving geometric information in the latent space, the proposed framework improves generalization and data-efficiency. The authors demonstrate the effectiveness of their approach by validating its ability to generalize to unseen spatial and temporal locations, as well as geometric transformations of the initial conditions.

This paper is about using a special kind of artificial intelligence called Conditional Neural Fields (NeFs) to solve complex math problems called partial differential equations (PDEs). PDEs are used to model many things in science and engineering, like how fluids flow or heat spreads. The problem with traditional ways of solving PDEs is that they don’t take into account the symmetries, or patterns, that exist in the real world. This new approach uses NeFs to capture those symmetries, which makes it better at predicting what will happen in different situations.
