New Hierarchical Representation Boosts Physics-Informed Neural Networks

By PulseAugur Editorial · [1 sources] ·

Researchers have introduced a novel Hierarchical Rank-Evolving (HRE) representation designed to enhance physics-informed neural networks (PINNs). This new method addresses limitations in existing tensor-based PINNs by automatically determining optimal ranks, thereby improving the capture of complex solution structures. Extensive experiments across various physics problems, including fluid dynamics and static equations, show that HRE-PINNs achieve superior accuracy compared to current state-of-the-art approaches.

    Hierarchical rank-evolving representation for physics-informed neural networks

    arXiv:2608.09483v1 Announce Type: new Abstract: Recently, tensor-based physics-informed neural networks (T-PINNs) have received increasing attention. However, existing T-PINNs still face a fundamental challenge: they mainly rely on pre-specified low-rank tensor decompositions wit…
