Researchers have developed a new method called Cut-DeepONet to improve how neural operators handle discontinuities and sharp transitions in partial differential equations. This approach partitions the domain into smooth regions and represents discontinuities as boundaries in a higher-dimensional space, avoiding direct approximation. An additional network predicts discontinuity locations for new inputs, guiding the main operator. Experiments show Cut-DeepONet outperforms existing methods, especially on low-resolution datasets, while using fewer parameters. AI
