The field of physics-informed neural networks (PINNs) is rapidly advancing, with a focus on developing innovative methods for solving complex problems in various domains. Recent research has explored the application of PINNs to optimal control problems, phase-field models, and inverse problems, demonstrating their potential for improving accuracy and efficiency. Notably, the integration of physical laws and constraints into neural network architectures has enabled the development of more robust and interpretable models. Furthermore, the use of PINNs has been extended to areas such as speech production, ultrasound-derived flow fields, and principal-agent problems, showcasing their versatility and broad applicability.
Some noteworthy papers in this area include: The paper Solving Infinite-Horizon Optimal Control Problems using the Extreme Theory of Functional Connections, which presents a novel approach for synthesizing optimal feedback control policies using PINNs. The paper A DeepONet joint Neural Tangent Kernel Hybrid Framework for Physics-Informed Inverse Source Problems and Robust Image Reconstruction, which introduces a hybrid framework for solving inverse problems using DeepONets and Neural Tangent Kernels. The paper Structure-Preserving Physics-Informed Neural Network for the Korteweg--de Vries (KdV) Equation, which proposes a structure-preserving PINN framework for solving the KdV equation, ensuring physically consistent and energy-stable evolution throughout training and prediction.
