English(EN) Hybrid-time PINNs: Discontinuity-Aware Physics-Informed Neural Networks for Learning Hybrid Dynamical Systems

新的PINN模型学习具有离散跳跃的混合系统

研究人员开发了混合时间PINNs(HT-PINNs),这是一种用于模拟同时具有连续流和离散跳跃的混合动力系统的新方法。与难以处理不连续性的传统PINNs不同,HT-PINNs为每个流区间使用单独的网络,并联合训练它们以识别跳跃时间和未知参数。该方法在准确预测跳跃次数和估计模拟中的物理参数方面取得了成功,例如在弹跳球和机器人拆卸任务中。 AI

影响 引入了一种模拟具有连续和离散动力学特性的复杂系统的新方法,有可能提高AI模拟和控制现实世界物理过程的能力。

    混合时间PINN:用于学习混合动力系统的非连续感知物理信息神经网络

    arXiv:2610.33562v1 Announce Type: cross Abstract: Hybrid dynamical systems flow continuously but jump at discrete events. Physics-informed neural networks (PINNs) fit data while enforcing known dynamics, but a single network is smooth in time and cannot model these jumps. We show…
