Auxiliary-Tasks Learning for Physics-Informed Neural Network-Based Partial Differential Equations Solving

1 code implementation12 Jul 2023 Junjun Yan, Xinhai Chen, Zhichao Wang, Enqiang Zhou, Jie Liu

To alleviate these issues, we proposed auxiliary-task learning-based physics-informed neural networks (ATL-PINNs), which provide four different auxiliary-task learning modes and investigate their performance compared with original PINNs.

ST-PINN: A Self-Training Physics-Informed Neural Network for Partial Differential Equations

1 code implementation15 Jun 2023 Junjun Yan, Xinhai Chen, Zhichao Wang, Enqiang Zhoui, Jie Liu

To address the issue of low accuracy and convergence problems of existing PINNs, we propose a self-training physics-informed neural network, ST-PINN.
