arXiv:2601.20361v2 Announce Type: replace Abstract: Physics-informed neural networks (PINNs) solve time-dependent partial differential equations (PDEs) by learning a mesh-free, differentiable solution that can be evaluated anywhere in space and time. However, standard space-time PINNs take time as an input but reuse a single network with shared weights across all times, forcing the same features to represent markedly different dynamics. This coupling degrades error performance and can destabilize training when enforcing PDE, boundary, and initial constraints jointly. We propose Time-Induced Ne
This research addresses a known limitation in standard Physics-informed neural networks (PINNs) where shared weights across time steps degrade performance for time-dependent problems, indicating ongoing refinement in AI for scientific computing.
Improving the accuracy and stability of neural networks for solving time-dependent partial differential equations (PDEs) has broad implications for scientific discovery, engineering, and various simulation-intensive industries.
The proposal of Time-Induced Neural Networks (TINNs) suggests a more robust and potentially more efficient method for modeling complex dynamic systems, advancing the state-of-the-art in AI for scientific applications.
