Physics-Informed Error Field Learning (PIEFL) is a post‑training optimization framework for Physics‑Informed Neural Networks (PINNs). After a primary network reaches satisfactory accuracy, PIEFL introduces an auxiliary error network that learns the discrepancy between the current approximation and the exact solution by deriving error control equations under physical constraints. The learned error correction is then combined with the primary prediction, improving solution accuracy without modifying the primary network architecture and focusing computational resources on correcting existing prediction errors.

The paper presents Finite Basis Physics-Informed Neural Networks (FBPINNs) and their multilevel extensions as a new approach to solving the Helmholtz equation. By decomposing the computational domain into overlapping sub‑domains, each governed by a local neural network, the method aims to improve accuracy and computational efficiency for high‑frequency wave problems in complex two‑dimensional domains. The authors evaluate the technique on the homogeneous Helmholtz case, showing its potential to overcome limitations of traditional finite difference and finite element methods.

The paper introduces NEXT, a new physics-informed neural architecture that combines Neuro‑Spectral Architectures with high‑order exponential time‑differencing integrators. NEXT integrates the stiff linear part of PDEs exactly via matrix exponentials while a neural network models the remaining nonlinear dynamics, thereby overcoming spectral bias, causality issues, and numerical instability seen in previous PINNs and NeuSAs. Benchmark tests on stiff PDEs show NEXT remains stable and accurate, and it can also solve inverse problems by learning unknown parameters or boundary conditions from sparse data.
