摘要:
本研究提出一种神经网络训练算法,其损失函数可分解为两个待最小化的非负项。该方法是对Inexact Restoration(非精确恢复)算法的改进,构成一种施加下降条件的两阶段方法。研究在PINN(物理信息神经网络)训练中开展了若干性能测试。
英文摘要:
This work presents an algorithm for training Neural Networks where the loss function can be decomposed into two non-negative terms to be minimized. The proposed method is an adaptation of Inexact Restoration algorithms, constituting a two-phase method that imposes descent conditions. Some performance tests are carried out in PINN training.
