Master Data‑Driven Neural Operators: DeepONet, POD‑DeepONet, FNO‑2D and Time‑Stepping FNO‑1D in One Tutorial

This tutorial presents a comprehensive JAX implementation and analysis of four neural‑operator methods—standard DeepONet, POD‑DeepONet, 2‑D Fourier Neural Operator, and time‑stepping 1‑D FNO—applied to the 1‑D advection equation, comparing their mathematical foundations, parameter counts, training efficiency, and prediction accuracy.

Spectral Division of Labor: How HINTS Blends Jacobi and DeepONet for Uniform PDE Convergence

The HINTS framework exploits the complementary spectral biases of classical Jacobi/Gauss‑Seidel relaxations and DeepONet neural operators, alternating them at a fixed ratio to achieve fast, uniform convergence for both positive‑definite and indefinite PDE systems, and integrates seamlessly with multigrid and Krylov solvers.
