Picking the Branch Is Not Solving the Problem: What an Imperfect Neural Operator Buys a Physics-Informed Network, Where Its Basin Information Comes From, and the Comparators That Decide Whether the Hybrid Pays
(c) 2026 Pranay Mahendrakar. Licensed under CC BY 4.0. Life of Research Physics-informed neural networks (PINNs) can minimise a PDE residual and still land on the wrong solution, while neural operators are cheap to evaluate but lose accuracy outside their training range. A 2026 study joins the…
