PINN framework overcomes noise and dimensionality limits in heat diffusion

Researchers have developed a Physics-Informed Neural Network (PINN) framework to address the limitations of traditional numerical methods like the Finite Difference Method (FDM) when dealing with noisy, high-dimensional heat diffusion problems. In simulations with 20% boundary noise in 3D, the PINN maintained approximately 91% accuracy, while FDM accuracy dropped to 36%. The PINN also demonstrated superior performance in a physical copper thermal system, reducing boundary reconstruction error by 3.3 times under realistic noise conditions, and proved more efficient than FDM in 3D scenarios.

影响 PINN framework offers a more accurate and efficient solution for complex thermal simulations, potentially impacting engineering and scientific modeling.
