cXGBoost 适配降阶模型以用于工程模拟

研究人员开发了一个名为 Constrained Extreme Gradient Boosting (cXGBoost) 的新框架,以提高工程模拟中使用的降阶模型 (ROM) 的准确性。该方法通过将 Proper Orthogonal Decomposition (POD) 基预测为系统参数的函数来适配 ROM 的基构造。通过利用 Grassmann 流形上的几何表示并在训练期间施加范数约束,cXGBoost 确保了逆映射的有效性并保留了预测子空间的几何结构,在各种复杂系统中表现出稳健的性能。 AI

影响 引入了一种新颖的机器学习方法,以提高复杂工程模拟的效率和准确性。
