Levi-Civita坐标在AI动力学研究中改善动力学,但恶化优化

研究人员探索了在学习到的Hamiltonian动力学中使用Levi-Civita坐标,并将其与扰动Kepler系统中的笛卡尔坐标形式进行了比较。Levi-Civita坐标在稳定性和准确性方面表现出优越性,尤其是在高偏心率下,但它们在原始基优化条件方面带来了挑战。研究发现,精确特征控制和正交化可以恢复L-BFGS的基线拟合,但即使在规范对称化后,小型MLP在滚动误差方面仍然存在困难,这表明这些动力学的精确神经残差学习仍然是一个开放性问题。 AI

影响 这项研究探索了Hamiltonian动力学的高级坐标系统,有可能提高复杂物理模拟中学习模型的准确性和稳定性。
