Researchers have developed a novel Spectral-Embedded Deep Operator Network (SEDONet) architecture to improve the approximation capabilities of DeepONets for complex problems in scientific computing. Unlike standard DeepONets that use fully connected layers on raw coordinates, SEDONet employs a Chebyshev spectral dictionary, providing an inductive bias suitable for bounded domains. This approach allows SEDONet to better capture fine-scale features, boundary layers, and non-periodic structures, outperforming baseline DeepONets and Fourier-embedded variants in terms of relative L2 errors across various benchmarks including the 2D Poisson equation and the Lorenz-96 chaotic system.
