摘要
最近在计算方法上的进展导致了一种专为水平集界面对流设计的无数据物理信息神经算子的开发。这种创新方法允许将初始界面映射到其时空轨迹，而无需依赖参考解，这与传统的监督学习方法有显著不同。结果表明，这种新方法不仅与现有的监督模型竞争良好，而且在特定基准测试中显示出较低的相对L2误差，同时在对流过程中有效地保持了封闭区域。
Recent advancements in computational methods have led to the development of a data-free physics-informed neural operator specifically designed for level-set interface advection. This innovative approach allows for the mapping of an initial interface to its spatiotemporal trajectory without relying on reference solutions, which is a significant departure from traditional supervised learning methods. The results indicate that this new method not only competes well with existing supervised models but also demonstrates a lower relative L2 error in specific benchmarks, while effectively conserving the enclosed area during the advection process.
