Physics-Informed Machine Learning: Bridging Data-Driven Models and Physical Laws
Year: 2025
Type: preprint
Abstract: Physics-Informed Machine Learning (PIML) represents a paradigm shift in computational modeling by integrating physical laws and constraints directly into machine learning frameworks. This approach addresses fundamental limitations of traditional data-driven methods, which often fail to maintain physical consistency and struggle with sparse, noisy data in high-dimensional systems. In this paper, we provide a comprehensive overview of PIML, covering its theoretical foundations, mathematical formulations, and key methodologies including Physics-Informed Neural Networks (PINNs) and neural operators. We demonstrate how PIML techniques can be applied across diverse domains including fluid dynamics, quantum computing, and environmental modeling. Through detailed case studies and performance evaluations, we illustrate the superior accuracy and data efficiency of PIML approaches compared to conventional methods. Our work serves as a comprehensive reference for researchers and practitioners seeking to leverage the synergy between machine learning and physical modeling.
