The novel framework introduced in this paper combines machine learning (ML) with traditional scientific methodologies to address computational and practical limitations. It synergizes physics-based priors with advanced ML techniques to tackle first-principle-based methods and brute-force approaches. The framework showcases four algorithms, each embedding a specific physics-based prior tailored to different classes of nonlinear systems. These priors preserve the system’s symmetries and conservation laws, ensuring physically plausible solutions and computational efficiency. The integration of these priors also enhances neural networks’ expressive power, capturing complex patterns in physical phenomena. As a result, the models outperform existing data-driven techniques in prediction accuracy, robustness, and predictive capability.

This paper introduces a new way to combine machine learning with science. It uses special rules based on physics to help machines learn about the world. This helps make predictions more accurate and reliable. The method is tested on different types of problems, like understanding how fluids move or predicting complex patterns in data. The results show that this approach can do better than other methods, even when working with small amounts of data.
