Operator Boosting Produces Pareto-Efficient PDE Surrogates
Researchers have developed a new framework called Operator Boosting to create more efficient neural network surrogates for solving partial differential equations (PDEs). This method trains smaller neural operators on residual fields in stages, progressively refining the predictions. The approach has demonstrated significant reductions in parameter counts, often between 72-95%, while achieving comparable or improved accuracy on various PDE benchmarks, including Navier-Stokes and Darcy flow.
