物理信息神经网络的新评估协议和嵌入方法

研究人员推出了PINNeval,这是一个新的评估协议和配套的JAX软件包PINNpipe,旨在系统地评估物理信息神经网络(PINNs)。该协议通过将PINN训练管道视为一个集成系统,并要求对所有组件进行有竞争力的实现,而不仅仅是正在研究的组件,从而解决了现有基准测试的局限性。另外,另一篇论文提出将Ermakov-Pinney尺度函数作为无参数嵌入整合到PINNs的输入层,并在包括线性扩散和量子振荡器在内的各种问题家族中证明了其有效性。 AI

影响 这些进展旨在提高PINN研究和应用的严谨性和有效性,有望为复杂的科学问题带来更可靠的解决方案。

    PINNeval:物理信息神经网络的综合评估标准

    The Physics-Informed Neural Network (PINN) literature has produced a rapidly expanding catalogue of methods. We divide a PINN training pipeline systematically into four components and observe that many existing benchmarks study these components in isolation. These components are …

    Ermakov--基于嵌入作为物理信息神经网络的无参数层

    Evolution equations with time-dependent coefficients force a neural solver to spend capacity on a scale that the equation already determines. We show that a single classical object, the Ermakov-Pinney scale function $ρ$, can be written into the input layer of a physics-informed n…
