arXiv:2509.24627v2 Announce Type: replace Abstract: Embedding physical intuition into network architectures allows the learning of dynamics that enforce fundamental properties, such as energy conservation laws, thereby leading to physically-plausible predictions. Yet, scaling these models to high-dimensional dynamical systems remains a significant challenge. This paper introduces Reduced-order Hamiltonian Neural Network (RO-HNN), a novel physics-inspired neural network that combines the conservation laws of Hamiltonian mechanics with the scalability of model order reduction. RO-HNN is built on
The increased scale and complexity of AI models, especially in physical simulations, necessitate more efficient and physically-grounded learning architectures.
This research addresses a critical limitation in AI's ability to model complex physical systems, opening avenues for more accurate and energy-conserving simulations in various scientific and engineering domains.
By combining Hamiltonian mechanics with model order reduction, AI models can now learn high-dimensional dynamics more scalably while inherently respecting fundamental physical laws, improving prediction accuracy and physical plausibility.

AI systems will become more adept at modeling and predicting complex physical phenomena with higher fidelity.
This could accelerate discoveries and optimizations in fields like materials science, aerospace engineering, and drug discovery by reducing computational costs and improving accuracy.
The enhanced predictive power might lead to novel designs and applications that were previously intractable due to computational limits or lack of physical coherence in AI models.
