Researchers have developed a novel method to improve the test-time generalization capabilities of neural operators, which are used to learn solutions for partial differential equations (PDEs). The proposed strategy involves splitting and composing existing neural operators at test time, enabling them to tackle unseen physics and parameter extrapolations without retraining. This approach achieves state-of-the-art zero-shot generalization results on challenging out-of-distribution tasks, demonstrating the potential of test-time computation for creating more flexible and compositional neural operators.
