TensorGalerkin 框架加速偏微分方程求解和学习

研究人员开发了一个名为 TensorGalerkin 的新算法框架,用于求解、优化和学习具有变分结构的偏微分方程 (PDE)。该框架利用高效的 Galerkin 离散化和 GPU 兼容的 TensorGalerkin 方法来装配线性系统。TensorGalerkin 方法在 PyTorch 的 autograd 中优化了逐元素操作,使得装配图与网格大小无关。跨各种 PDE 类型的基准测试表明,与现有的数值求解、约束优化和物理信息算子学习方法相比,在计算效率和准确性方面均有显著提升。 AI

影响 引入了一种新颖的物理信息算子学习框架,有望加速 AI 驱动的科学发现。
