English(EN) Do physics-informed neural networks (PINNs) need to be deep? Shallow PINNs using the Levenberg-Marquardt algorithm

使用Levenberg-Marquardt算法的浅层PINNs显示出高精度

一篇新的研究论文探讨了使用Levenberg-Marquardt(LM)算法优化的浅层物理信息神经网络(PINNs)的有效性。研究表明,与Adam和BFGS等其他优化方法相比,当与LM结合使用时,浅层PINNs可以实现更快的收敛速度、更高的精度和更低的损失值。研究表明,对于各种非线性偏微分方程,具有有效二阶优化的浅层PINNs提供了一种计算效率高且准确的解决方案,其性能可能优于参数更少的深度网络。 AI

影响 提出了一种使用神经网络求解复杂微分方程的更有效、更准确的方法。
