New architecture learns mechanical system dynamics using position data on Lie groups

Researchers have developed a novel architecture for learning the dynamics of mechanical systems using discrete forced Euler-Lagrange equations on Lie groups. This method leverages only position data, naturally preserving geometric structures and conservation laws by formulating dynamics directly on manifold-valued configuration spaces. The approach is versatile, extending to multibody systems and external control inputs, and has shown effectiveness on both synthetic and real-world datasets, particularly in scenarios where velocity data is scarce or unreliable. AI
