A new strategy for physics-informed neural networks based on hierarchical collocation point refinement

Minjae Choi, Dukhwan Shin, Youngsoo Yang +1

The paper proposes a multigrid-inspired training scheme for physics‑informed neural networks that starts with a coarse set of collocation points and progressively refines them, red…
