The paper introduces the Physics-Informed Stochastic Configuration Machine (PI‑SCM), a backpropagation‑free neural network designed for solving nonlinear differential equations. By analytically evaluating local Jacobians, PI‑SCM linearizes the physical loss, enabling optimal weight determination through generalized linear least squares and avoiding iterative nonlinear optimization. The authors present a progressive algorithmic suite—PI‑SC‑I, PI‑SC‑II, and PI‑SC‑III—prove their universal approximation properties, and show through experiments that PI‑SCM achieves high‑fidelity predictions and parameter identification while accelerating training by orders of magnitude compared to standard PINNs.

The paper introduces neural network nudging, a data‑driven method for learning observation‑driven control terms in nonlinear state‑space models. It builds on Kazantzis–Kravaris–Luenberger observer theory to prove the existence of such terms and demonstrates the approach on three chaotic benchmarks: Lorenz 96, Kuramoto–Sivashinsky, and Kolmogorov flow.

The paper introduces a linearized Physics-Informed Neural Network (lPINN), a reduced‑order neural basis approach for solving forward and inverse differential equations. In an offline phase, lPINN learns continuous, differentiable neural basis functions from numerical solutions, which are then frozen for new problem instances; the online solution is obtained by minimizing the governing‑equation residual with additional constraints. Experiments on advection‑diffusion, Burgers', and nonlinear pendulum equations show that lPINN achieves lower solution and parameter errors than vanilla PINNs while reducing online inference times by up to three orders of magnitude, and its continuous representation generalizes to finer meshes without retraining.

The paper introduces a two‑stage training framework for neural network observers that guarantees Lyapunov stability for uncertain dynamical systems. First, a point‑guided Lyapunov pre‑training phase quickly achieves high estimation accuracy and local stability over sampled states. Second, an LMI fine‑tuning phase efficiently enforces a strict global Lyapunov stability certificate, yielding provably stable observers that train faster than direct LMI methods and generalize robustly across diverse systems.
