TENG++: Time-Evolving Natural Gradient for Boundary-Enhanced PINNs
Published in arXiv preprint, 2025
Extended the Time-Evolving Natural Gradient (TENG) framework with Dirichlet boundary constraints in PINNs; implemented a Jacobian-based natural-gradient least-squares stepper and integrated it with Euler/Heun time-stepping. Validated on heat-equation benchmarks with analytical solutions.
